Problems solved by technology

[0006] Aiming at the problem that the existing injection mold mentioned in the background technology needs to be additionally equipped with a driving device to take off, upside down, and out of the mold, resulting in complex mold structure and cumbersome operation steps, the present invention provides a handle forming mold, which is matched with conventional opening and closing by a transmission mechanism. The mold and mold closing procedure can realize that the inte

Abstract

The invention discloses a handle forming mold. The handle forming mold comprises a mold body, the mold body comprises an upper compound plate and a lower compound plate assembly, a mold cavity is formed below the upper compound plate, a mold core is arranged above the lower compound plate assembly, a handle internal forming device is arranged between the mold core and the lower compound plate assembly, the handle interior forming device comprises a transmission mechanism and a forming assembly connected to the transmission mechanism, the forming assembly can be driven by the transmission mechanism through mold closing force to carry out interior forming of a handle product, and the forming assembly can be driven by the transmission mechanism through mold opening force to carry out undercut removing of the handle product. According to the transmission mechanism, in the mold closing process, the handle interior forming device is abutted with the handle product for forming, in the mold opening process, the product is ejected out, the undercut part is avoided, the undercut removing action is completed, demolding is achieved, the mold structure is effectively simplified, additional auxiliary power participation is reduced, the continuous action of mold opening, undercut removing and demolding is achieved, and the production cost is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a handle forming mold. Background technique [0002] Injection mold is a tool for producing plastic products; it can mass produce certain plastic parts with complex shapes. Injection molds are usually composed of a movable mold and a fixed mold. During production, the mold is installed in the injection molding machine, and the plastic that is heated and melted is injected into the cavity of the injection mold by high pressure by the injection molding machine. After cooling and solidifying, the injection molding machine operates to make The movable mold is separated from the fixed mold, and then the injection-molded finished product is pushed out by the ejector mechanism to complete one injection. [0003] Especially for the handles of some box and frame products, the inner R angle is usually increased due to the needs of daily use, so as to ensure that daily use will ...
