[0002] The mold is the main tool for molding plastic products. Its precision, surface finish and structural complexity directly affect the quality of plastic products. If there is dirt, rust or damage on the mold surface, it will affect the fluidity and filling of the plastic material in the mold, thereby affecting the molding quality and appearance of the plastic product. For this reason, the mold needs to be cleaned and maintained regularly. A patent authorization announcement number of CN 219360144 is retrieved, which is an injection mold that is easy to clean. The patent needs to replace the mold cover with a side cover on the top of the mold body, and then spray the cleaning water through the nozzle on the connecting pipe to flush the inside of the injection cavity.
