Injection molding machine

Abstract

The invention discloses an injection molding machine which comprises an injection molding pipe provided with a feed port, a screw rod positioned in the injection molding pipe, an injection mold and a cooling water tank, wherein a plurality of convex blocks are uniformly arranged on an inner wall of the injection molding pipe; a heat preservation layer is arranged on the outer surface of the injection molding pipe; the injection molding pipe is connected with a strong heating electricity box and a weak heating electricity box; the cooling water tank is communicated with the injection mold mutually through a water inlet pipe and a water outlet pipe; and an air compressor is arranged on the water inlet pipe. The injection molding machine shortens the service time of a material pushing process, and improves the production efficiency of a product; the air compressor can provide high pressure to cooling water, to allow that no melt in the mold deforms easily in a cooling process; and the quality of the product is ensured.

Description

technical field [0001] The invention specifically relates to an injection molding machine. Background technique [0002] Injection molding machine is a very common machine in modern industrial production. Its principle is to heat the plastic raw material to melt it to obtain a melt formed by the plastic raw material. The injection molding machine then injects the obtained melt into the plastic mold. Then use the hydraulic cylinder to drive the upper mold to press down the lower mold. After the pressing is completed, the lower mold is cooled. After cooling, the corresponding plastic products can be obtained. However, the injection tubes used to melt plastic raw materials in existing injection molding machines are usually The inner wall is very smooth, so that the screw used to push the plastic material is easy to drive the plastic material to rotate around the screw during the process of rotating and pushing, which makes the progress of the whole pushing process quite slo...

Then use the hydraulic cylinder to drive the upper mold to press down the lower mold. After the pressing is completed, the lower mold is cooled. After cooling, the corresponding plastic products can be obtained. However, the injection tubes used to melt plastic raw materials in existing injection molding machines are usually The inner wall is very smooth, so that the screw used to push the plastic material is easy to drive the plastic material to rotate around the screw during the process of rotating and pushing, which makes the progress of the whole pushing process quite slow, and the production efficiency is also greatly affected. The pressure of the melt in the mold is too small, and the melt is prone to deformation during the cooling process, which seriously affects the molding quality of the product.
