Hexagonal cap production die

Abstract

The utility model provides a hexagonal cap production die, and belongs to the technical field of dies. The die solves the problem that the die service life is short due to the fact that the size of a cavity of a lower die of an existing hexagonal cap production die is easy to increase. The hexagonal cap production die comprises an upper die body with a cavity formed in the bottom and a lower die body with a hexagonal boss at the top, a groove body is formed in the middle of the lower die body in a downward penetrating mode from the hexagonal boss, a lower ejection device is arranged in the groove body, a groove cavity with the columnar upper end and the trapezoidal lower end is formed in the upper die body, and a positioning shaft is arranged in the groove cavity. The cavity is communicated with the groove cavity, and the positioning shaft is pressed on the top of the hexagonal cap blank. The utility model has the advantages of preventing the cavity from becoming larger, improving the working efficiency and prolonging the service life.

Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and relates to a production mold, particularly a hexagonal cap production mold. Background Technology

[0002] Hexagonal cap, with an opening at the bottom and a closed structure at the top.

[0003] Currently, the production of hexagonal caps involves molding the product into a lower mold, which has a cavity for product molding. However, in actual processing, it has been found that prolonged production can lead to an increase in cavity size, resulting in a shorter mold life. Furthermore, with the increased size and no change in the upper mold, flash at the hexagonal position is prone to ejection, causing material jamming in the cavity during processing. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a hexagonal cap production mold to solve these problems.

[0005] The purpose of this utility model can be achieved through the following technical solution: A hexagonal cap production mold, characterized in that it includes an upper mold with a cavity at the bottom and a lower mold with a hexagonal boss at the top. The lower mold has a groove extending downward through the hexagonal boss in the middle. A lower ejector device is provided in the groove. The upper mold has a groove with a columnar upper end and a trapezoidal lower end. A positioning shaft is provided in the groove. The cavity is connected to the groove, and the positioning shaft presses against the top of the hexagonal cap blank.

[0006] In the aforementioned hexagonal cap production mold, the lower ejection device is a hydraulic cylinder with a cylinder rod.

[0007] In the aforementioned hexagonal cap production mold, the upper mold has a guide rod, and the lower mold has a guide groove.

[0008] Compared with existing technologies, this hexagonal cap production mold has the advantages of preventing the cavity from becoming larger, improving work efficiency and service life. Attached Figure Description

[0010] Figure 2 This is an exploded cross-sectional view of the production mold for the hexagonal cap.

[0011] In the diagram, 1 is the cavity; 2 is the upper mold; 3 is the hexagonal boss; 4 is the lower mold; 5 is the groove; 6 is the lower ejector device; 7 is the cavity; 8 is the positioning shaft; 9 is the guide rod; and 10 is the guide groove. Detailed Implementation

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, this hexagonal cap production mold includes an upper mold 2 with a cavity 1 at the bottom and a lower mold 4 with a hexagonal boss 3 at the top. A groove 5 extends downwards from the hexagonal boss 3 through the middle of the lower mold 4, and a lower ejector device 6 is installed within the groove 5. The upper mold 2 has a cavity 7 with a columnar upper end and a trapezoidal lower end, and a positioning shaft 8 is installed within the cavity 7. The cavity 1 communicates with the cavity 7, and the positioning shaft 8 presses against the top of the hexagonal cap blank. The hexagonal cap blank is placed on the hexagonal boss manually or by a robot. The upper mold presses down, and the positioning shaft 8 contacts the hexagonal cap blank. The blank is deformed by forging to form the hexagonal cap product. Through the combination of a lower convex shape and an upper concave shape, with the positioning shaft 8 abutting against it, the product is positioned during processing, preventing deviation and thus avoiding wear from contact with the cavity 1 wall, which could lead to increased space.

[0014] Furthermore, after the product is formed, it corresponds to and overlaps with each side of the hexagonal boss 3.

[0015] Preferably, the lower ejector device 6 is a hydraulic cylinder with a cylinder rod.

[0016] To elaborate further, the upper mold 2 has a guide rod 9 on its exterior, and the lower mold 4 has a guide groove 10 on its exterior, which serve to cooperate and guide each other during operation.

[0017] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0018] Although this document frequently uses terms such as cavity 1, upper mold 2, hexagonal boss 3, lower mold 4, groove 5, lower ejector device 6, cavity 7, positioning shaft 8, guide rod 9, and guide groove 10, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
