[0020] In one embodiment, the left side of the inclined top is provided with a first inclined surface, and the inclination direction of the first inclined surface is the same as the length direction of the inclined guide rod;

[0021] The right side of the large pusher block is provided with a second inclined surface, which matches the first inclined surface.

[0022] In one embodiment, the straight-top and angled-top structure further includes a longitudinal guide rod that passes through the bottom of the large push block and connects to the bottom of the small push block; the longitudinal guide rod is arranged parallel to the longitudinal ejector rod.

[0023] The inclined guide rod passes through the bottom of the large push block and connects to the bottom of the inclined top. Attached Figure Description

[0040] Combination Figures 1 to 7 As shown, this utility model provides a structure with a straight top and an inclined top, which is applied to a fixed template 50. It includes a push block assembly comprising a large push block 210, a small push block 220, and an inclined top 230 located between the large push block 210 and the small push block 220. The large push block 210 is movably connected to the fixed template, the inclined top 230 is movably connected to the large push block 210, and the small push block 220 is movably connected to the inclined top 230. The small push block 220 and the inclined top 230 together form the forming surface of the product 10; a reserved gap 240 is also provided between the small push block 220 and the inclined top 230, the reserved gap 240 is used to accommodate the longitudinal extension 110 of the product 10; a longitudinal ejector rod 310 is connected to the bottom of the large push block 210; an inclined guide rod 320 is connected to the inclined top 230; a transverse guide rod 330 passes through the small push block 220 and is connected to the inclined top 230;

[0041] Specifically, during mold closing, the large push block 210, the small push block 220, and the inclined ejector 230 together form the forming surface of the product 10. Furthermore, a reserved gap 240 is provided between the small push block 220 and the inclined ejector 230 so that the product 10 can be formed and the longitudinal extension 110 can be formed in the reserved gap 240.

[0042] During mold opening, the push block assembly is ejected once under the action of the longitudinal ejector rod 310, that is, the large push block 210, the inclined ejector 230 and the small push block 220 are ejected upward together, so that the product 10 is partially separated from the fixed mold plate. Subsequently, the inclined ejector 230 moves obliquely upward along the length direction of the inclined guide rod 320, and moves away from the small push block 220 along the length direction of the transverse guide rod 330 to perform a second ejection and increase the reserved gap 240. At this time, the upper end of the inclined ejector 230 is higher than the large push block 210 and the small push block 220, thereby ejecting the product 10. Due to the increased space of the reserved gap 240, the longitudinal extension 110 can be demolded smoothly.

[0043] Compared with the prior art, the straight ejector with inclined ejector 230 structure of this application completes the first ejection of the entire push block assembly under the action of the longitudinal ejector rod 310, causing the product 10 to partially detach from the fixed mold. Subsequently, the inclined ejector 230 moves obliquely upward, and the small push block 220 moves away from the inclined ejector 230 to perform a second ejection and increase the reserved gap 240, so that there is enough space for the longitudinal extension 110 of the product 10 to be demolded, thus solving the problem of difficult demolding of the product 10.

[0044] In this embodiment, the right side of the inclined ejector 230 is also provided with a plurality of positioning blocks 231; the upper side of the small push block 220 is provided with a plurality of positioning grooves 221, the positioning grooves 221 matching the positioning blocks 231; when the mold is closed, the positioning blocks 231 are located in the positioning grooves 221, and the cooperation between the positioning grooves 221 and the positioning blocks 231 ensures the position of the inclined ejector 230 and the small push block 220 when the mold is closed, and ensures that the longitudinal extension 110 is formed within the reserved gap 240.

[0045] In this embodiment, the right side of the inclined top 230 is provided with a plurality of first protrusions 232, and the plurality of first protrusions 232 match the longitudinal through holes 111 on the longitudinal extension 110 so that the longitudinal through holes 111 on the longitudinal extension 110 are formed.

[0046] In this embodiment, a support portion 233 is also provided on the right side of the inclined top 230, and the support portion 233 is located below the positioning block 231. When the mold is closed, the upper part of the small push block 220 is in contact with the upper side of the support portion 233, and the lower part of the small push block 220 is in contact with the right side of the support portion 233. The support portion 233 supports the small push block 220, thereby reducing the weight of the transverse guide rod 330 from the small push block 220.

[0047] In this embodiment, the product 10 is further provided with a lateral extension 120, and the lateral extension 120 is provided with a lateral through hole 121; when the mold is closed, the lateral extension 120 is attached to the upper side of the small push block 220, and the upper side of the small push block 220 is provided with a second protrusion 222, which matches the lateral through hole 121 so that the lateral extension 120 and the lateral through hole 121 are formed.

[0048] In this embodiment, the left side of the inclined top 230 is provided with a first inclined surface, and the inclination direction of the first inclined surface is the same as the length direction of the inclined guide rod 320; the right side of the large push block 210 is provided with a second inclined surface, and the second inclined surface matches the first inclined surface so that the inclined top 230 can move obliquely upward along the second inclined surface.

[0049] In this embodiment, the straight-top and angled-top structure further includes a longitudinal guide rod 340, which passes through the bottom of the large push block 210 and connects to the bottom of the small push block 220; the longitudinal guide rod 340 is arranged parallel to the longitudinal ejector rod 310; the angled guide rod 320 passes through the bottom of the large push block 210 and connects to the bottom of the angled-top 230.

[0050] Specifically, during the second ejection, the longitudinal guide rod 340 pushes the small push block 220 upward, and the small push block 220 moves upward. Due to the relationship between the small push block 220 and the inclined push 230, the inclined push 230 then moves obliquely upward, thereby increasing the reserved gap 240.

[0051] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
