Accelerated demoulding mechanism of injection mold of automobile interior trim

Abstract

The invention discloses an accelerated demoulding mechanism of an injection mold of an automobile interior trim. The mechanism comprises a B plate (1), a face needle plate (2), a bottom needle plate (3), a bottom plate (4) and a first ejector rod (5), and further comprises an accelerated driving mechanism. The accelerated driving mechanism comprises a second ejector rod (6), the top of the secondejector rod (5) is movably telescopic inside and outside a second through hole of the B plate (1), one part of the bottom of the second ejector rod (6) is attached to the top surface of the bottom needle plate (3), the other part of the bottom of the second ejector rod (6) is connected with the accelerated driving mechanism, and the accelerated driving mechanism is positioned in an internal cavityformed by the surface needle plate (2) and the bottom needle plate (3). Two-step mould opening is realized through the accelerated driving mechanism for demoulding, demoulding is realized through one-time demoulding and two-time ejection actions, the structure is simple, the reliability is realized, and a protrusion can be prevented from being torn.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an accelerated demoulding mechanism for injection molds of automotive interior parts. Background technique [0002] Such as figure 1 As shown, there is currently an automotive interior part, including an interior part 101, and a protrusion 102 is provided on the bottom surface of the interior part 101. The existing injection molding is that when the mold is opened again, the conventional ejector pin is used for demoulding, which will cause the raised ribs to wrap around the ejector pin, making it difficult to pick up the parts with a robot, and it is impossible to achieve the goal of fully automatic unmanned. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of automotive interior parts that realizes demoulding by one demoulding and two ejecting actions, and has a simple structure and reliability, realiz...
