[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1-Figure 6 The utility model provides an embodiment: a plastic mold forming structure, comprising: a male mold core 1; one side of the male mold core 1 cooperates with a plurality of oblique pin structures 2, a processing piece 3 is arranged on the outside of the male mold core 1 and the oblique pin structure 2, a slider 4 is arranged on the outside of the processing piece 3, the slider 4 cooperates with the oblique pin structure 2, one side of the oblique pin structure 2 is subjected to force, so that the processing piece 3 moves in the direction of the forming section 21, performs extrusion molding, and performs mold closing molding on the processing piece 3; one side of the oblique pin structure 2 is provided with a beveled edge, which cooperates with the processing piece 3;
[0031] In this embodiment, one side of the male mold core 1 cooperates with the oblique pin structure 2, and the male mold core 1 and the oblique pin structure 2 are inserted into the inner side of the workpiece 3. The forming section 21 on the oblique pin structure 2 is pressed to mold the workpiece 3. When the oblique pin structure 2 cooperates with the workpiece 3, the oblique pin structure 2 is located at the workpiece 3 to form a gap. During assembly, the oblique pin structure 2 and the male mold core 1 are quickly positioned and inserted into the inner side of the workpiece 3. When the die is disassembled, the gap formed also facilitates the disassembly and removal of the oblique pin structure 2.
[0032] The oblique pin structure 2 includes: a forming section 21 and a connecting section 22 , which are integrally connected; the side of the forming section 21 away from the male mold core 1 is recessed inward, so that the slider 4 squeezes the workpiece 3 and extends to the inner side of the forming section 21 .
[0033] In this embodiment, the molding section 21 and the connecting section 22 of the oblique pin structure 2 are integrally connected, and an inclined surface is provided on both side end faces of the molding section 21. When the molding process is performed, a cylinder is connected to one side of the slider 4 to push the slider 4 to move in the direction of the molding section 21 and extend into the inner side of the recessed part of the molding section 21 to form the workpiece 3. There is a certain gap between the inclined surfaces on both sides of the molding section 21 and the workpiece 3, so that the oblique pin structure 2 can be easily removed after the molding is completed.
[0034] The extending section 21 and the forming section 21 are provided with inclined surfaces on both sides, and the angle between the inclined surfaces and the vertical direction is 3°-5°.
[0035] In this embodiment, inclined surfaces are provided on both sides of the molding section 21. During the die-casting process, the molding section 21 extends into the inner side of the workpiece 3 so that the positions of the molding section 21 and the slider 4 correspond. During the die-casting process, there is a gap between the molding section 21 and the workpiece 3 to prevent the molding section 21 from deforming and squeezing the outer side of the workpiece 3 to produce burrs during the die-casting process.
[0036] The connecting section 22 is disposed on an end surface of the molding section 21 away from the workpiece 3 ; the side surface of the connecting section 22 and the side surface of the molding section 21 form a step shape.
[0037] In this embodiment, the connecting section 22 is integrally connected to the forming section 21 and forms a step shape on the side of the forming section 21. When the die is pressed, the connecting section 22 cooperates with one side of the male mold core 1 to limit the position in the vertical direction.
[0038] The connecting section 22 is inclined toward one side of the forming section 21 , and the inclination angle is 2°-4°.
[0039] In this embodiment, the connecting section 22 is bent toward the outside of the male mold core 1, and the bending angle is greater than or equal to the angle of the conical barrel of the male mold core 1, so as to avoid the connecting section 22 being squeezed into the inner side of the workpiece 3 during the molding process, resulting in the molding section 21 and the slider 4 not being able to fit accurately, and at the same time facilitate the removal of the oblique pin structure 2 through the connecting section 22.
[0040] The workpiece 3 and the male mold core 1 are conical, and the male mold core 1 is inserted into the inner side of the workpiece 3; the side of the workpiece 3 with a larger opening extends outward to form a gap with the male mold core 1, and the molding section 21 extends into the inner side of the gap.
[0041] In this embodiment, the side with the larger opening of the workpiece 3 is set to a rectangle, and corresponding oblique pin structures 2 can be set in four directions, so that the four end surfaces can be die-formed. The four oblique pin structures 2 can be die-formed at one time, which improves the processing efficiency.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
