Description

Technical Field

[0001] The utility model relates to the technical field of plastic machines, in particular to a plastic machine which is convenient for cleaning molds. Background Art

[0002] Plastics processing is the process of transforming plastic raw materials into various finished products through a series of processes. These products can range from daily necessities to industrial parts and packaging materials. Plastics processing requires a variety of processing machines, including plastic molding machines, blow molding machines, extruders, and calenders. A plastic molding machine is a device used to process plastic raw materials and shape them into various shapes. A heating system melts the plastic raw material, injects it into a mold, and then cools it under pressure to form the finished product. Plastic molding machines play a vital role in modern industry.

[0003] However, the existing plastic machines have the following disadvantages. During the processing of the plastic machine, the plastic raw materials are molded in the inner cavities of the upper mold and the lower mold, and then the molded plastic workpiece is taken out. However, due to various conditions of the plastic material, some residues will adhere to the inner wall of the upper mold, and the upper mold is not easy to clean. The residues are retained in the inner cavity of the upper mold, which will reduce the quality of subsequent plastic processing. Therefore, the existing plastic machines need to be improved.
