Problems solved by technology
[0003] In the process of preparing plastic products, the existing injection molding machines have certain defects in melting plasticization and feeding. Among them, in melting plasticization, it is easy to fail to fully melt the plastic raw materials entering the pouring delivery pipe, resulting in There are differences in the process of pressure injection, and the product molding cannot be carried out well, resulting in a decrease in the yield; in addition, in terms of feeding, when granular or powdery plastics are added to the feeding channel, it is easy to be blocked, and Raw materials cannot be allowed to enter the pouring conveying pipe, resulting in production stagnation

The invention discloses an anti-blocking plastic injection molding machine comprising an operating platform. The operating platform is fixed to ground by anchor bolts, and the upper surface of the operating platform is provided with a moving die, a fixed die, an injection delivery pipe and a support platform, wherein the moving die, the fixed die, the injection delivery pipe and the support platform are connected to each other from left to right in sequence; and the left end of the moving die is connected to a telescopic cylinder, and one end, far away from the moving die, of the telescopic cylinder is connected to an air pipe. The anti-blocking plastic injection molding machine has the beneficial effects that plastic particles entering the injection delivery pipe can be uniformly heated by heating rings installed along the periphery of the injection delivery pipe, and products are formed uniformly after pressure injection; the production efficiency is improved; and in addition, through a dispersion device and an injection device which are arranged in a feeding channel, excessive negative pressure in the feeding channel is avoided through a pressure-relief channel and the injectionchannel, and the effect of circulation is good.
Description
technical field [0001] The invention relates to the technical field of injection molding machines, in particular to an anti-blocking plastic injection molding machine. Background technique [0002] The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous flow state) into the closed cavity. The process of obtaining products after curing and setting. Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and picking. After taking out the plastic parts, the mold is closed again, and the next cycle is carried out. Injection molding machine operation items: Injection molding machine operation items include three aspects: control keyboard operation, electrical control system operation and hydrauli...
