Plastic extruding machine

Abstract

The invention discloses a plastic extruding machine. The plastic extruding machine comprises a machine frame, a raw material processing mechanism comprises a heating cavity arranged in the machine frame, a first motor is fixedly installed on the end surface of the top of the machine frame, an output shaft at the lower side of the first motor is fixedly connected with a motor shaft, the motor shaft penetrates through the heating cavity and is matched with the bottom wall of the heating cavity in a rotating mode, the plastic raw material is conveyed into a hopper, the plastic raw material in the hopper enter the heating cavity through a feeding pipeline, and a heating assembly heats the raw material in the heating cavity. An air cylinder is used for pushing the raw material to carry out injection molding, the internal clearance is small, so that plastic in an injection molding cavity can be completely used up, before the injection molding, the melted plastic can be extruded firstly, so that air inside the injection molding cavity is completely removed, and the injection molding effect is ensured.

Description

Technical field [0001] The invention relates to the field of injection molding, in particular to a plastic extruder. Background technique [0002] Plastic products are generally processed by injection molding. General injection molding machines use screw rods for plastic injection. However, this injection molding method is likely to cause uneven heating of the plastic. The screw rod is always rotating in the injection cavity, and the internal clearance is relatively large. Large, the inside is easy to be adhered to by plastic when not in use, making the second use difficult and the inside of the injection molded plastic is rich in air, which makes the plastic injection molded product effect poor. Summary of the invention [0003] The object of the present invention is to provide a plastic extruder for overcoming the above-mentioned defects in the prior art. [0004] The plastic extruder according to an embodiment of the present invention includes a frame, and a material processing ...

Problems solved by technology

[0002] Plastic products are generally processed by injection molding. Ordinary injection molding machines use screw rods to transport the injection materials. However, this injection molding method tends to cause uneven heating of the plastics. The screw rods are always rotating in the injection cavity, and the internal clearance is relatively large. Large, the inside is easy to be attached by plastic when not in use, making it difficult to use for the second time. At the same time, the inside of the injection molded plastic is rich in air, which makes the product effect of the injection molded plastic poor
