[0024] Example:
[0025] Reference Figure 1-Figure 5, a composite mechanism of a slider with double inclined tops, comprising: a wear-resistant block 5, which is fixed to one of the molds by bolts, and a sliding seat 2 is slidably connected to the wear-resistant block 5 by a pressure strip, and a slider insert 207 is fixedly arranged at one end of the sliding seat 2, and the slider insert 207 corresponds to the position of the product fastener, and a water transport adapter block is fixedly arranged on the side wall of the sliding seat 2 for convenient cooling; a shovel machine 1 is fixedly arranged on the other mold, and the two molds are used in conjunction with each other, and an inclined guide column 101 is fixedly arranged on the shovel machine 1, and an inclined guide hole 201 corresponding to the inclined guide column 101 is opened on the sliding seat 2. When the two molds are close, the inclined guide column 101 on the shovel machine 1 slides into the inclined guide hole 201 and drives the sliding seat 2 and the slider insert 207 to slide to achieve mold closing. On the contrary, when the two molds are far away, the inclined guide column 101 slides out of the inclined guide hole 201 to achieve demoulding; two groups of symmetrically arranged inclined top pieces 4, on the wear-resistant block 5 is slidably provided with an inclined ejector seat 3, one end of the two groups of inclined ejector pieces 4 are slidably provided on the inclined ejector seat 3, and the other ends of the two groups of inclined ejector pieces 4 are slidably connected to the slider insert 207, and the other ends of the two groups of inclined ejector pieces 4 are fixedly provided with inserts corresponding to the product undercuts. When in use, when the sliding seat 2 slides, the two groups of inclined ejector pieces 4 approach or move away from each other to achieve a mold closing or demoulding effect. When closing the mold, the inclined guide column 101 slides into the inclined guide hole 201 to drive the sliding seat 2 and the slider insert 207 to approach the undercut position on the product. During this process, the sliding seat 2 can drive the two groups of inclined ejector pieces 4 to approach each other to achieve a mold closing effect; conversely, when demoulding, the inclined guide column 101 drives the sliding seat 2 and the slider insert 207 to move away from the product, and then the sliding seat 2 can drive the two groups of inclined ejector pieces 4 to move away from each other, thereby achieving demoulding. The structure is simple, the demoulding effect is reliable, and the demoulding stroke is short, which helps to improve production efficiency.
[0026] Reference Figure 3 and Figure 4 A mounting groove 202 is provided at the bottom of the sliding seat 2, and one end of the inclined top seat 3 away from the wear-resistant block 5 is slidably connected in the mounting groove 202. Through grooves 203 connected to the mounting groove 202 are respectively provided on both sides of the sliding seat 2, and limiting blocks 204 are respectively fixedly provided in the two groups of through grooves 203. Driving grooves 304 are respectively provided on both sides of the inclined top seat 3, and the two groups of limiting blocks 204 are slidably connected with the corresponding driving grooves 304. When in use, by fixing the limiting blocks 204 on both sides of the sliding seat 2, during demoulding, when the sliding seat 2 is away from the product for a certain distance, the limiting blocks 204 and the inner wall of the driving groove 304 away from the slider insert 207 are abutted, which can push the inclined top seat 3 to move with the sliding seat 2, thereby improving the demoulding effect.

During this process, since the limit pin 6 on the inclined top seat 3 is engaged with the second groove 501 on the wear-resistant block 5, the inclined top seat 3 cannot move, and the sliding seat 2 can drive the ends of the two groups of inclined top members 4 with inserts to move away from each other, thereby achieving the demoulding effect from the fasteners of the product. When the inserts of the inclined top members 4 are completely detached from the product, the first groove 205 slides to the top of the limit pin 6, and the limit block 204 also just abuts against the inner wall of the driving groove 304 away from the slider insert 207. When the sliding seat 2 continues to move, the bottom of the limit pin 6 disengages from the second groove 501, disengaging from the engagement state with the second groove 501, and the top slides into the first groove 205. At this time, the limit block 204 can push the inclined top seat 3 to move with the sliding seat 2 to achieve demoulding.
