Description
Technical Field
The invention relates to the field of molds, in particular to a mold for injection molding.
Background
The injection mold is a tool for producing plastic products; is also a tool for endowing plastic products with complete structure and precise dimensions. Injection molding is a process used in mass production of parts of complex shape. Specifically, the heated and melted plastic is injected into a die cavity under high pressure by an injection molding machine, and a formed product is obtained after cooling and solidification.
The injection mold is often divided into an upper mold and a lower mold, and the raw materials are molded after the upper mold and the lower mold are clamped. Because there is the gap in junction after last mould and lower mould block, gap and die cavity intercommunication for outside dust impurity easily enters into the inside of die cavity, and the inside remaining impurity of die cavity can cause the influence to the product of making subsequently, makes the quality of product reduce to some extent. The dust outside the mould can also enter the inside of die cavity in the placing process, and the mould needs to be cleaned when the mould is used again subsequently, so that the working efficiency is affected. And the raw materials in the die cavity are excessive and then easily leak from the joint, so that the raw materials are scattered on the working surface, and the raw materials need to be cleaned later, thereby causing inconvenience to normal work.
