Detailed Product Description: | Version: basic knowledge of plastic mold products and technology applications a the modular plastic mold for compression molding, extrusion, injection molding, blow molding, and low-foam molding, which mainly includes the substrate by die combination, die components and die combination of card board the variable cavity die punch combinations substrate, the punch assembly punch combination card board, cavity the truncated components and side cut-off combination plates with variable core punch. Mold convex, die and assisted molding system coordination change. Machinable different shapes, different sizes series of plastic parts. Our day-to-day production, life used to a variety of tools and products, large machine tool base, body shell, small embryo head screws, buttons and a variety of household appliances shell, all with the mold has a close relationship. The shape of the mold determines the shape of these items, the quality and accuracy of the machining of the mold will determine the quality of these products. Different because of a variety of products, materials, appearance, specifications, and use, the mold is divided into a casting mold, forging mold, die casting mold, stamping mold and other non-plastic mold, plastic mold. 1, in recent years, with the continuous improvement in the strength and accuracy of the rapid development of the plastics industry and general engineering plastics, plastic products range is constantly expanding, such as: household appliances, instruments and meters, construction equipment, automotive industry , daily hardware, and many other areas, the proportion of plastic products is rapidly increasing. A well-designed plastic parts can often replace multiple traditional metal pieces. Industrial products and consumer products, plastic of the trend is rising. 2, the general definition of the mold: in industrial production, with a variety of presses and a special tool is mounted on the press, through the pressure of metal or non-metallic materials, the desired shape of the parts or articles, such special tools are collectively referred to as the mold . 3, the injection molding process: mold tool is a production of plastic products. It consists of several groups of parts to the mold cavity, this combination successful. When injection molding, the mold clamping, the injection molding machine, the molten plastic is injected into the mold cavity, and cooling and shaping in the cavity, and then separated from the upper and lower molds via the top of the system, the top of the article from the mold cavity leaving the die, and finally the mold is closed again, the next injection, the injection molding process cycle. 4, the general classification of the mold: can be divided into plastic molds and non-plastic mold: (1) non-plastic mold: the casting mold, forging mold, stamping mold, die casting mold. A. Casting mold - faucets, pig iron platform B. The forging die - car body C. The stamping mold - computer panel D. Die-casting mold - super alloy cylinder block (2) plastic mold according to the different production processes and production products are divided into: A. Injection Molding - TV shell, keyboard button (most common) B. The blowing mold - drink bottles C. Compression molding die - Bakelite switch, science bowl dish D. The Transfer Molding mold - integrated circuit products E. Extrusion mold - glue tubes, plastic bags and F. Thermoforming mold - is transparent molded packaging shell G. Rotational molding mold - the soft rubber dolls ◆ injection molding method is most commonly used in plastic processing. The method is suitable for all thermoplastics and thermosetting plastics, obtained by the large number of plastic products is unmatched by other forming methods, as injection molds for injection molding tools, quality precision manufacturing cycle and injection molding process level in production efficiency, a direct impact on product quality, yield, cost and product updates, and also determines the ability to respond to market competition and speed. ◆ injection mold by a number of steel plates with a variety of parts, basically divided into: A molding device (die, punch) B-positioning device (I.-I. sets) C fixtures (the word board code mode pits ) D cooling system (carrying water hole) E thermostat system (heating pipe, the hotline) F runner system (jack Tsui hole, runner slot, runner holes) G ejector system (thimble, top stick) 5, according to the pouring system made different and the mold is divided into three categories: (1) the large nozzle mold: the flow channel and the gate at the parting line, with product in the open mold releasing, the most simple design, easy to process, cost than low, so more and more people using the large nozzle system operations. (2) fine outlet molds: the runner and gate is not parting line, the general directly on the product, so you want to design more than a group of outlet parting line, the design is more complex, more difficult processing, generally depending on the product requirements and selection fine nozzle system. (3) hot runner mold: such a mold structure, and the fine nozzle substantially the same, the maximum difference is the flow channel in one or more of the thermostat of the hot runner plate and the thermal jack mouth, without releasing of cold material, the flow channel and the pouring port directly on the product, so the flow path does not require stripping, no intake system, this system is also called to saving raw materials applicable to the expensive, raw materials and products require a higher design and processing difficulties, high cost of the mold. Hot runner system, also known as hot runner system, mainly composed of hot sprue bush, hot runner plate, thermostat electrical box. Common hot runner hot runner single point and multi-point hot runner system has two kinds of forms. Single-point thermal gate directly with a single hot sprue bush molten plastic is injected into the cavity, it applies to a single-chamber single plastic mold gate; multi-point thermal gate hot runner plate the molten material Mycobacterium each sub hot sprue bush into the cavity, it applies to the single-chamber multi-point into the material or multi-cavity mold the runner system's advantages (1) outlet material, does not require post-processing the entire molding process is completely automated. save time, improve work efficiency. (2) the pressure loss is small. Equal to the temperature of the hot runner temperature and the injection molding machine nozzle, to avoid surface condensation phenomenon of the raw material within the sprue, the injection pressure loss is small. (3) outlet material reuse cause the plastic performance degradation, and no outlet material using a hot runner system, can reduce the loss of raw materials, thereby reducing the cost of the product. Uniform temperature and pressure in the cavity, the stress of plastic parts, uniform density, the smaller injection pressure, shorter molding time better than the injection system, injection products. For transparent pieces of thin pieces of large plastic parts or high-demand plastic parts to better display its advantages, and can use smaller models to produce a larger product. (4) hot nozzle standardization, serialization design, with a variety to choose from the nozzle head, good interchangeability. The unique design of the electric heating coil processing, to achieve uniform heating temperature, long service life. Hot runner system is equipped with hot runner plate, thermostat, compact design, species diversity, and easy to use, stable and reliable quality. Hot runner system applications inadequacies (1) overall mold shut height increase, and increase the overall height of the mold due to the installation of hot runner plate. (2) thermal radiation is difficult to control, the hot runner runner of the biggest problems is the heat loss is a need to address the major issue. (3) presence of thermal expansion, thermal expansion and contraction to consider when we design. (4) mold manufacturing cost increases, higher prices of hot runner system standard accessories, affect the popularity of hot runner mold. |
