Problems solved by technology

However, in general, when installing the filter screen, many companies directly restrict the movement of the filter screen by pressing the dynamic mold on the filter screen. Before the dynamic mold presses the filter screen, the filter screen is still relatively easy to move, which will affect the quality of the final product

Abstract

Provided is an injection mold for a net rack. The injection mold comprises a fixed mold with a concave mold template. A connection plate is arranged on one side face of the fixed mold. The connection plate and the fixed mold are provided with a conveying device with a conveying filter screen. One set of side faces of the fixed mold are each provided with two first lifting air cylinders. The first air cylinders are close to the top corners of the concave mold template; the ends of the first air cylinders are provided with pressing rods; lifting rods corresponding to the ends of the pressing rods are arranged in the fixed mold; and the concave mold template is provided with through holes allowing the lifting rods to penetrate through. According to the injection mold for the net rack, the filter screen is clamped through cooperation of the pressing rods and the lifting rods so that the filter screen can be placed on the concave die template accurately, and thus the accuracy is ensured when the filter screen is placed on the concave mold template, the filter screen is prevented from slipping or creasing when a movable mold covers the fixed mold, and the production efficiency and quality of the finished filter screen are greatly improved accordingly.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to a grid 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. For the grid frame used for injection molding to fix the air conditioner filter screen, the filter screen needs to be placed on the concave mold of the fixed mold before injection molding, and then the screen of the filter screen is injected according to the flow channel of the grid structure structure that needs to be injected. frame, so that the filter screen is integrated with the grid frame. However, in gener...
