Detailed Implementation

[0020] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1: As Figures 1-3 As shown, a slider release structure with synchronous mechanical drive for ejection includes a slider 1, a guide rail 2, and a guide block 3; the slider 1 is slidably fitted to the rear mold core 4 and the rear mold plate 5, the front end of the slider 1 is the forming part 101, and the main body of the rear end of the slider 1 is provided with a groove with an inclined surface; the guide rail 2 is connected to the ejector plate 6, the top end of the guide rail 2 is slidably fitted to the groove, the top end of the guide rail 2 is provided with an inclined surface, and the inclined surface of the guide rail 2 fits against the inclined surface of the groove.

[0022] The rear mold core 4 is connected to the rear template 5 by bolts, and the forming part 101 is slidably fitted to the rear mold core 4; the main body is slidably fitted to the rear mold core 4 and the rear template 5.

[0023] The bottom of the main body is provided with protrusions 102 on both sides, and two pressure strips 7 are connected to the rear template 5. The upper surface of the protrusions 102 is slidably fitted to the upper surface of the pressure strips 7.

[0024] A lower wear-resistant block 8 is connected to the rear template 5 at the bottom of slider 1, and a rear wear-resistant block 9 is connected to the rear end of slider 1.

[0025] A further improvement of this utility model is that the guide rail 2 includes a vertical part 201 and an inclined part 202, and the slide groove includes a vertical groove part 103 and an inclined groove part 104. The vertical part 201 is slidably engaged with the vertical groove part 103, and the inclined part 202 is slidably engaged with the inclined groove part 104.

[0026] The vertical part 201 of the guide rail 2 is slidably fitted to the guide block 3.

[0027] A limit block 10 is connected to the rear template 5, and the rear end of the slider 1 can contact the limit block 10.

[0028] The specific working principle of this utility model is as follows: like Figures 4-6 As shown, the plastic product 11 is a hook cover. The snap-fit ​​of the product 11 with the undercut 1101 is formed on the slider 1 structure of the rear mold. This slider 1 structure is driven by the guide rail 2 structure, which is fixed on the ejector plate 6. When the mold ejects, the inclined part 202 at the top of the guide rail 2 presses the inclined groove 104 inside the slider 1, causing it to move backward. At the same time, the product 11 is ejected upward along with the ejection structure on the ejector plate 6 during the backward movement of the slider 1, avoiding the problem of scraping glue when the slider 1 structure moves. By calculating the mating surface angle at the top of the guide rail 2, it can be ensured that the product 11 can smoothly disengage from the undercut 1101 and complete the ejection and removal of the part.

[0029] The mold structure of this utility model features a slider 1 that disengages during the ejection process, resulting in a simpler structure, smaller mold size, and reduced mold manufacturing cycle and cost.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
