Plastic mold technology application

Pieces of injection molding is the most widely used in plastics processing methods. This method is applicable to all thermoplastics and part of thermosetting plastics, plastic kids playgrounds made the great number of them is the other forming methods of dust, as the main tool of injection molding processing, one of the injection mould, the quality of precision, manufacturing cycle and injection molding production efficiency in the process of the level of high and low, directly affect the product quality, yield, cost and product updates, at the same time also determines the enterprise in the market competition ability and speed of reaction.
Pieces of injection mold is made up of several steel plate with various parts, basic is divided into:
A forming device (die and punch)
B positioning device (guide pin, guide sleeve)
C fixtures (h board, code die hole)
D cooling system (hole)
E thermostatic system (heating tube, hot line)
F jungle playground system (pumping of nozzle hole flow channel slot and port holes)
G ejection system (thimble, top stick)
5, depending on the system of pouring system type of mould can be divided into three categories:
(1) the gate of mould, the runner and gate on the parting line, together with the product in the mould stripping, the simplest design, easy processing, low cost, so more people using gate system operation.
(2) nozzle mould: the runner and gate is not the parting line, generally directly on the product, so to design a set of shuikou parting line, design is relatively complex, processing more difficult, often depending on the product requirements to choose fine nozzle system.
(3) the hot runner mold: this kind of mold is approximately the same structure and fine shuikou, the biggest difference is that flow into one or more of the temperature of heat flow but and heat pumping mouth, no cold feeding demoulding, runner and gate directly on the product, so the port don't need mold release, also known as no runner system, this system can save raw materials, applicable to the raw material is more expensive, high requirement of products, design and processing difficulties, mould cost is higher.
