Mold for injection molding

Abstract

The invention relates to the field of molds, in particular to a mold for injection molding. The mold comprises an upper mold and a lower mold, the upper mold is installed above the lower mold, a sealing mechanism is arranged above the lower mold and comprises blocking plates and sealing gaskets, blocking plates are slidably installed on the periphery of the upper portion of the lower mold, the sealing gaskets are connected to the sides, facing the lower mold, of the blocking plates, transverse plates are horizontally connected to the two ends of the side face of the upper portion of the lower mold, the blocking plates are slidably installed above the transverse plates, and sliding grooves are formed in the interiors of the transverse plates in the sliding direction of the blocking plates. When the mold is not used, dust cannot enter a space between the upper mold and the lower mold easily through the sealing gaskets, cleaning is not needed during subsequent reuse, the step of cleaning the mold is omitted, when the blocking plates move to the joint between the upper mold and the lower mold, the end part is blocked through an elastic plate, blocking between the upper mold and the lower mold is more sufficient and comprehensive, and the blocking effect is better.

Description

technical field [0001] The invention relates to the field of molds, in particular to a mold for injection molding. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] Injection molds are usually divided into upper mold and lower mold. After the upper mold and lower mold are engaged, the raw materials are formed. After the upper mold and the lower mold are engaged, there will be a gap at the joint, and the gap is connected with the cavity, so that external dust and impurities can easily enter the cavity, and the residual impurities inside...

AI Technical Summary

Problems solved by technology

After the upper mold and the lower mold are engaged, there will be a gap at the joint, and the gap is connected with the cavity, so that external dust and impurities can easily enter the cavity, and the residual impurities inside the cavity will affect the subsequent products. , which reduces the quality of the product

During the placement of the mold, the external dust will also enter the interior of the mold cavity, and the mold needs to be cleaned when the mold is used again, which will affect the efficiency of the work

Moreover, if there are too many raw materials inside the cavity, it is easy to leak from the connection, causing the raw materials to spill on the working surface, requiring follow-up cleaning, causing inconvenience to normal work
