Problems solved by technology

[0005] The disadvantages of the structure of the above method are: when the inclined guide post is introduced into the two-color mold slider structure, since the two-color mold slider structure does not perform side core pulling, the alignment between the inclined guide post and the introduction hole is not accurate, and the inclined guide post cannot be inserted into the introduction hole

Embodiment Construction

[0038] The technical solutions in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back...) in this embodiment are only used to explain the relative relationship between the various components in a certain posture (as shown in the drawing). When the positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, in the present invention, descriptions such as "first", "second" and so on are...

Abstract

The invention discloses a bicolor die sliding block structure. The bicolor die sliding block structure comprises a sliding block body, an extending platform and a telescopic buckle mechanism. The extending platform comprises a guiding-in hole which is in a long bar shape. The telescopic buckle structure comprises a buckle. The buckle comprises a buckle body and an extending arm. A containing space partly containing the side wall of an inclined guide pillar is formed between the extending arm and the buckle body. The side wall of the inclined guide pillar abuts against the extending arm. The inclined guide pillar drives the extending arm so as to achieve the side core pulling action. The invention further discloses a sliding block core pulling mechanism. The sliding block core pulling mechanism comprises the inclined guide pillar and the bicolor die sliding block structure. The bicolor die sliding block structure is connected to a rear die in a sliding manner, and the inclined guide pillar is fixed to a front die. The inclined guide pillar is guided in the extending platform from the guiding-in hole. By means of the technical scheme, it can be ensured that in the second-time injection molding process of a bicolor die, the inclined guide pillar can be accurately aligned with the guiding-in hole.

Description

technical field [0001] The invention relates to a two-color mold slider structure for two-color mold forming and a slider core-pulling mechanism using the two-color mold slider structure. Background technique [0002] The two-color mold requires two injection moldings: the first injection of hard rubber and the second injection of soft rubber. [0003] In the existing process flow, it is usually required that the two-color mold slider structure cannot be core-pulled after the first injection molding. After the mold is opened, the mold is rotated 180°, and then the mold is closed. After the second injection molding is completed, the mold is opened again. At this time, the two-color mold slider structure can perform core-pulling action. [0004] The structure of the two-color mold slider has an introduction hole for the introduction and extraction of the inclined guide post. In the related technology, the cross section of the introduction hole is circular, and the inclined g...
