One end of the product Pt (such as Figure 4 The product Pt is shown in the dotted area RG (shown in the dotted area RG). The hook Hk is adjacent to the opening Pg). In this embodiment, the product Pt may be a tri-proof lamp, and one end of the tri-proof lamp is a sensing interface; the opening Pg is located on the sensing interface of the tri-proof lamp, and it has the hook Hk. In another embodiment, the product Pt may also be various existing lighting devices; the opening Pg is located on the connector of the lighting device, and it has the hook Hk.
[0031] The slider module 12 includes a slider 121, a slider pressing plate 122, an inclined guide column 123 and a slider core 124. The upper surface of the slider 12 has a first hole H1, a second hole H2 and an inclined guide groove H3. The slider pressing plate 122 is movably disposed in the first hole H1. The inclined guide column 123 passes through the mold body 12 (the inclined guide column 123 passes through the mold frame A plate 111 of the mold body 12) and is inserted into the inclined guide groove H3. There is an angle between the inclined guide column 123 and the upper surface of the slider 12; this angle can be an acute angle (this angle can be between 45 degrees and 85 degrees). The slider core 124 is movably placed in the second hole H2, one end of the slider core 124 is inserted into the opening Pg and one side of the slider core 124 has a groove Gv. In this embodiment, the slider core 124 is cylindrical. In another embodiment, the slider core 124 is a rectangular body (a cuboid or a cube). The slider pressing plate 122 may be a rectangular body. In the present embodiment, the slider pressing plate 122 is a cuboid. In another embodiment, the slider pressing plate 122 may also be a cube.
[0032] When the slider 121 moves, the slider pressing plate 122 in the first hole H1 on the upper surface of the slider 121 also moves simultaneously. When the slider pressing plate 122 reaches the position corresponding to the groove Gv, a part of the slider pressing plate 122 falls into the groove, while another part of the slider pressing plate 122 remains in the first hole H1. Then, the slider 121 continues to move, so that the slider pressing plate 122 pushes the slider core 124 in a direction away from the product Pt, so that the slider core 124 and the end of the product Pt having the opening Pg and the undercut Hk are separated from each other, so as to complete the demoulding.
[0033] As can be seen from the above, in this embodiment, the mold 1 includes a mold body 11 and a slider module 12. The mold body 11 has a containing space.

The slider module 12 includes a slider 121, a slider pressure plate 122, an inclined guide column 123 and a slider core 124. The upper surface of the slider 121 has a first hole H1, a second hole H2 and an inclined guide groove H3. The slider pressure plate 122 is movably arranged in the first hole H1. The inclined guide column 123 passes through the mold body 11 and is inserted into the inclined guide groove H3, and an angle is formed between the inclined guide column 123 and the upper surface. The slider core 124 is movably placed in the second hole H2, one end of the slider core 124 is inserted into the opening Pg and one side of the slider core 124 has a groove Gv. The above-mentioned slider undercut forced demoulding mechanism adopts an integrated structure of the slider 121 and the slider pressure plate 122, which can realize the one-time demoulding of the slider 121 and the slider core 124, so it can effectively prevent the product Pt from being damaged and better meet the needs of practical applications.
[0034] In addition, in this embodiment, the mold 1 has a slider undercut forced demoulding mechanism, which adopts an integrated structure of a slider 121 and a slider pressure plate 122. The above integrated structure is small in size and does not take up too much space. Therefore, the mold 1 can be more widely used and more flexible in use.
[0035] In addition, in this embodiment, the mold 1 has a slider undercut forced demoulding mechanism, which adopts an integrated structure of a slider 121 and a slider pressure plate 122. The above integrated structure is small in size and does not take up too much space. Therefore, the mold 1 can also reduce the cost of processing operations to enhance the market competitiveness of the product.
[0036] Furthermore, in this embodiment, the mold 1 has a slider undercut forced demoulding mechanism, which adopts an integrated structure of the slider 1211 and the slider pressing plate 22. The structure of the integrated structure is simpler, so the overall cost of the mold 1 can be effectively reduced.
[0037] Of course, this embodiment is only used for illustration and is not intended to limit the scope of the present invention. Equivalent modifications or changes made to the mold with a slider undercut forced demolding mechanism according to this embodiment should still be included in the patent scope of the present invention.
[0038] It is worth mentioning that most of the existing injection molding processes use an integrated structure of a large slider and a small slider (the small slider is arranged in the large slider) to assist in demolding. Some undercuts in the product design cannot be demolded in one go, and require secondary demolding to complete, so it is easy to damage the product. However, the volume of the above-mentioned integrated structure is too large and will take up a lot of space. In addition, the above-mentioned integrated structure also greatly increases the cost of the mold. On the contrary, according to an embodiment of the utility model, the mold includes a mold body and a slider module. The mold body has a accommodating space. The product is arranged in the accommodating space, and one end of the product has an opening and a hook, and the hook is adjacent to the opening. The slider module includes a slider, a slider pressure plate, an inclined guide column and a slider core. The upper surface of the slider has a first hole, a second hole and an inclined guide groove. The slider pressure plate is movably arranged in the first hole. The inclined guide column passes through the mold body and is inserted into the inclined guide groove, and there is an angle between the inclined guide column and the upper surface. The slider core is movably placed in the second hole, one end of the slider core is inserted into the opening and one side of the slider core has a groove. The above-mentioned slider undercut forced demoulding mechanism adopts an integrated structure of a slider and a slider pressure plate, which can realize one-time demoulding of the slider and the slider core, thereby effectively preventing the product from being damaged and better meeting the needs of practical applications.
[0039] Furthermore, according to the embodiment of the utility model, the mold has a slider undercut forced demoulding mechanism, which adopts an integrated structure of a slider and a slider pressure plate. The above integrated structure is small in size, so it does not take up too much space. Therefore, the mold with the slider undercut forced demoulding mechanism can be more widely used and more flexible in use.

At this time, the inclined guide column 123 will drive the slider 12 to move away from the product Pt (as shown by the arrow A1 in the figure).
[0044] Then, when the slider 121 moves, the slider pressing plate 122 in the first hole H1 on the upper surface of the slider 121 also moves simultaneously. When the slider pressing plate 122 reaches the position corresponding to the groove Gv, a part of the slider pressing plate 122 falls into the groove, while another part of the slider pressing plate 122 remains in the first hole H1. Then, the slider 121 continues to move, so that the slider pressing plate 122 pushes the slider core 124 in a direction away from the product Pt, so that the slider core 124 and the end of the product Pt having the opening Pg and the undercut Hk are separated from each other, so as to complete the demoulding, and realize the undercut strong release of the product Pt.
