[0033] Reference Figure 1-Figure 7 The driving member 4 includes an inclined rod 41 and a sliding seat 42. The sliding seat 42 is slidably connected to the ejector plate 14 along a direction perpendicular to the mold opening direction of the mold. A guide rod 151 is fixedly connected to the rear mold panel 15. The axial direction of the guide rod 151 is inclined to the mold opening direction of the mold. The end of the guide rod 151 away from the rear mold panel 15 is penetrated by the ejector plate 14 and the sliding seat 42 and is fixedly connected to the cavity plate 1. A slide rail 421 is fixedly connected to the sliding seat 42. A slider 422 is slidably connected to the slide rail 421 along the mold opening direction inclined to the mold. The inclined rod 41 is penetrated and slidably connected to the cavity plate 1 along the mold opening direction inclined to the mold. One end of the inclined rod 41 is fixedly connected to the inclined ejector block 11. The end of the inclined rod 41 away from the inclined ejector block 11 is hingedly connected to the sliding seat 42. The axial direction of the inclined rod 41 intersects with the axial direction of the guide rod 151.
[0034] Reference Figure 1-Figure 7 When the ejector plate 14 slides toward the cavity plate 1, the slide rail 421 slides along the guide rod 151 and slides relative to the ejector plate 14 in a direction perpendicular to the mold opening direction of the mold, and the slider 422 slides toward the sliding block along the slide rail 421. When the angle between the inclined rod 41 and the ejector plate 14 is large, the product can be ejected at a large angle, reducing the possibility of the inclined rod 41 getting stuck or broken during the sliding process.

The contact block 221 always contacts the guide block 222. The spring 223 is sleeved on the push block 21. The two ends of the spring 223 contact the sliding groove and the contact block 221 respectively. The spring 223 always drives the contact block 221 to slide toward the side of the guide block 222. When the inclined ejector block 11 slides toward the side away from the cavity plate 1, the contact block 221 slides along the surface of the guide block 222.
[0037] Reference Figure 1-Figure 7 When the mold is opened, the inclined ejector block 11 slides toward the side away from the cavity plate 1, so that the abutment block 221 slides along the surface of the guide block 222, and the push block 21 slides along the surface of the guide block 222, and then the push block 21 slides toward the side away from the inclined ejector block 11, pushing the rib 51 on the product out of the inclined ejector block 11, reducing the possibility of product damage during demoulding.
[0038] Reference Figure 1-Figure 7 , and also includes a side withdrawal mechanism 3 at the rib position 51, which is used for side withdrawal of the rib position 51 part on the product. The side withdrawal mechanism 3 at the rib position 51 includes a side withdrawal block 31 with a molding surface and a driving component 32. The side withdrawal block 31 is slidably connected to the cavity plate 1 at an angle to the mold opening direction of the mold, and the driving component 32 is used to drive the side withdrawal block 31 to slide.
[0039] Reference Figure 1-Figure 7The driving component 32 includes a guide block 33 and a cylinder 34. The guide block 33 is slidably connected to the cavity plate 1 along a mold opening direction perpendicular to the mold. A guide groove 334 is provided on the guide block 33.

The cylinder 34 is fixedly connected to the cavity plate 1, and one end of the piston rod of the cylinder 34 is fixedly connected to the guide block 33.
[0040] Reference Figure 1-Figure 7 , the cylinder 34 is started to drive the guide block 33 to slide, so that the side withdrawal block 31 slides along the guide groove 334, and the side withdrawal block 31 slides relative to the cavity plate 1. When the mold is opened, the driving component 32 drives the side withdrawal block 31 to slide toward the side away from the product, so that the side withdrawal block 31 is separated from the rib 51 on the product, reducing the possibility of the product being pulled up.
[0041] Reference Figure 1-Figure 7 In summary, when the mold is opened, the ejector plate 14 moves toward the side of the cavity plate 1, and through the connection of the inclined rod 41, the inclined ejector block 11 moves toward the side away from the cavity plate 1, so that the inclined ejector block 11 ejects the product. When the inclined ejector block 11 moves, the abutment block 221 slides along the surface of the guide block 222, so that the guide block 222 slides toward the side away from the receiving groove 12, so that the push block 21 slides toward the side away from the inclined ejector block 11, and the rib 51 of the product is pushed out from the inclined ejector block 11, reducing the possibility of product damage. At the same time, the cylinder 34 drives the guide block 33 to slide toward the side away from the receiving groove 12, so that the side drawer block 31 slides relative to the molding surface of the cavity plate 1 toward the side away from the molding surface of the cavity plate 1.
[0042] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
