Problems solved by technology

[0002] Injection mold is a tool for producing plastic products. It consists of two parts: a movable mold and a fixed mold. During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to remove the plastic. The product, the elbow is a large-angle arc. According to the existing technology, according to the ordinary core-pulling mechanism, the mechanism takes up a lot of space, the movement distance is long, and it cannot be demoulded quickly. It will interfere with the structure of other parts of the product, so that the arc cannot be realized at all. Core pulling, poor movement stability

Abstract

The invention discloses an automobile elbow core-pulling mechanism, which includes a product and a lower template, the product is located on the lower template, an arc-shaped groove is arranged inside the product, and an annular protrusion is arranged at the front end of the product. A circular groove is arranged inside the annular protrusion, the diameter of the circular groove is greater than the diameter of the arc groove and the circular groove communicates with the arc groove, and the circular groove for forming is provided in the described circular groove. The first core insert on the inner wall, the arc groove is provided with a second insert core for forming the inner wall of the arc groove, it also includes the first linear core pull for the circular groove core pull mechanism and the second arc core-pulling mechanism for core-pulling the arc groove, the first core insert and the second insert core are connected together, and the second arc core-pulling mechanism is located under On the formwork, the invention provides an automobile bent pipe core-pulling mechanism that is not easy to damage the product and has high reliability.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an automobile elbow core-pulling mechanism. Background technique [0002] Injection mold is a tool for producing plastic products. It consists of two parts: a movable mold and a fixed mold. During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to remove the plastic. The product, the elbow is a large-angle arc. According to the existing technology, according to the ordinary core-pulling mechanism, the mechanism takes up a lot of space, the movement distance is long, and it cannot be demoulded quickly. It will interfere with the structure of other parts of the product, so that the arc cannot be realized at all. Core pulling, poor movement stability. Contents of the invention [0003] The technical problem to be solved by the present invention is: to ...
