Problems solved by technology

Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. However, when processing similar products such as air conditioner filters, since both sides of the filter need to be injected, two injection molding processes are required, resulting in a process. It is cumbersome, and when the product is injected, the material is often solidified before it fills the cavity, which affects the product quality

Abstract

The invention discloses an injection mold for a filter screen and belongs to the technical field of injection molds. By means of the injection mold for the filter screen, the filter screen can be molded at a time and a cavity is made to be filled with materials. According to the technical scheme, the injection mold is characterized by comprising a movable mold, an intermediate plate and a fixed mold; the movable mold comprises a concave mold fixing plate; the fixed mold comprises a cushion plate; the concave mold fixing plate is provided with a first concave mold; the side, facing the concave mold fixing plate, of the intermediate plate is provided with a second concave mold matched with the first concave mold; the side, deviating from the second concave mold, of the intermediate plate is provided with a runner; the inner side, facing the intermediate plate, of the runner is provided with a secondary runner perpendicular to the intermediate plate; the side, facing the first concave mold, of the intermediate plate is provided with a plurality of fixing rods used for suspension of the filter screen, and the fixing rods are perpendicular to the intermediate plate; and the concave mold fixing plate is provided with first fixing holes matched with the fixing rods.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a filter net injection mold. 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 material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. However, when processing similar products such as air conditioner filters, since both sides of the filter need to be injected, two injection molding processes are required, resulting in a process. It is cumbersome, and when the product is injected, the material is often solidified before the cavity is filled, which affects the product quality. Contents of the invention [0003] Aiming at the defici...
