A special wave-shaped centralized venting structure for die casting molds

Abstract

This utility model relates to the field of die-casting molds, and more particularly to a special wave-shaped centralized venting structure for die-casting molds. It includes an upper cavity punching mold, a lower cavity punching mold, and a mold cavity. It includes a special wave-shaped venting groove. The lower cavity punching mold has an annular block with a height higher than the outer ring around its perimeter. The annular block has multiple first venting channels, which bend downwards along the edge steps of the annular block and extend to the outer ring. The ends of the first venting channels connect to the special wave-shaped venting groove. The cross-section of the special wave-shaped venting groove is wave-shaped, and the inner contour line of the groove is serrated. The special block is inserted into the special wave-shaped venting groove to form a wave-shaped venting structure. This device uses a special wave-shaped venting groove with the same width as existing venting grooves, but improves the thickness by making it wave-shaped, thereby indirectly increasing the width of the venting groove and accelerating the venting efficiency.

Description

Technical Field

[0001] This utility model relates to the field of die casting molds, and in particular to a special wave-shaped centralized venting structure for die casting molds. Background Technology

[0002] When die-casting products, the mold itself is filled with air. When the upper mold is pressed into the lower mold, the air needs to be expelled quickly so that the die-cast products can reduce the generation of air holes. However, the current molds use rectangular toothed venting channels, which have low venting efficiency. Therefore, based on this technical problem, we designed a special wave-shaped centralized venting structure for die-casting molds. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a special wave-shaped centralized venting structure for die casting molds, including an upper cavity punching mold, a lower cavity punching mold, and a mold cavity, including a special wave-shaped venting groove. The lower cavity punching mold has an annular block with a height higher than the outer ring around its cavity. The annular block has multiple first venting channels. The first venting channels bend downwards along the edge steps of the annular block and extend to the outer ring of the annular block. The end of the first venting channel is connected to the special wave-shaped venting groove. The cross-section of the special wave-shaped venting groove is wave-shaped, and the outline of the inner side of the groove is toothed. The upper cavity punching mold has a special block that matches the special wave-shaped venting groove. The special block is inserted into the special wave-shaped venting groove to form a wave-shaped venting structure.

[0004] The first exhaust channel has an isosceles trapezoidal connecting groove at its end. One end of the short horizontal side of the connecting groove is connected to the first exhaust channel, and the long horizontal side of the connecting groove is connected to a special wave-shaped exhaust groove.

[0005] Three quick exhaust slots are symmetrically arranged on both sides above the annular block, and each quick exhaust slot is connected to a first exhaust channel.

[0006] The beneficial effects of this utility model are as follows:

[0007] This device uses a special wavy exhaust groove with the same width as the exhaust groove in the existing technology, but improves the thickness by setting it in a wavy shape, thereby indirectly increasing the width of the exhaust groove and accelerating the exhaust efficiency.

[0014] See Figure 1-4 .

[0015] This case involves improvements to the venting plate area of ​​a die-casting mold, while other structures are existing technologies. Therefore, this case will not elaborate on the other structures.

[0016] This utility model discloses a special wave-shaped centralized venting structure for die casting molds, including an upper cavity punching mold, a lower cavity punching mold, and a mold cavity 2. It includes a special wave-shaped venting groove 5. The lower cavity punching mold has an annular block 3 with a height higher than the outer ring around its cavity. The annular block has multiple first venting channels 4, which bend downwards along the edge steps of the annular block and extend to the outer ring. The end of each first venting channel is connected to the special wave-shaped venting groove 5. The cross-section of the special wave-shaped venting groove is wave-shaped 51, and the inner contour line of the groove is toothed 52. The upper cavity punching mold has a special block 61 that matches the special wave-shaped venting groove 5. The special block is inserted into the special wave-shaped venting groove 5 to form a wave-shaped venting structure.

[0017] The first exhaust channel has an isosceles trapezoidal connecting groove 7 at its end. One end of the short horizontal side of the connecting groove is connected to the first exhaust channel, and the long horizontal side of the connecting groove is connected to the special wave-shaped exhaust groove 5.

[0018] Three quick exhaust slots 8 are symmetrically arranged on both sides above the annular block, and each quick exhaust slot is connected to a first exhaust channel.

[0019] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
