Description

Technical Field

[0001] The utility model relates to an improved tooling structure for solving cracks in cassette products, belonging to the technical field of molds. Background Art

[0002] When the cassette product 11 is formed by the gap between the upper mold and the lower mold 2, the bottoms of the two cassette products 11 are symmetrically attached to the two sides of the core 3, and the ends 12 of the cassette products 11 are connected to the side surfaces of the insert 4 and the top surface of the core 3, as shown in FIG. Figure 5 shown.

[0003] When the core 3 is demolded from the lower mold 2 with the cassette-like product 11, the end 12 of the cassette-like product 11 is not easily separated from the side surfaces of the insert 4 and the top surface of the core 3. The end 12 is easily torn by the tensile force of the side surfaces of the insert 4 and the top surface of the core 3, resulting in a crack, which leads to a low yield of the cassette-like product 11. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an improved tooling structure for solving cracks in cassette products.

[0005] The utility model is realized through the following technical solutions.

[0007] An upper mold and a lower mold with a core installed;

[0008] The lower mold located at both ends of the core is provided with grooves for installing inserts; the upper mold is provided with grooves for installing inserts, and the inserts are symmetrically half-stuck in the upper mold and the lower mold;

[0009] The end of the core has a reserved section for the cassette product to form a part to be punched.

[0010] The lower die is provided with a groove on which a core is installed; the insert is positioned and installed with the upper die and the lower die through a positioning pin A.

[0011] The core surface is provided with a mold removal recess, and the mold removal recess corresponds to the middle part of the insert.

[0012] The middle sides of the upper die and the lower die are positioned and installed by positioning pins B.

[0013] The lower mold corresponding to the core is provided with a top hole, and a top column is installed in the top hole.

[0014] The top posts are distributed in multiple intervals; the bottom of the top posts is fixed on the stripping plate, and the stripping plate is spaced apart from the bottom surface of the lower mold.

[0015] The sides of the upper mold and the lower mold are provided with force handles for performing mold closing or demoulding operations.

[0016] The beneficial effect of the utility model is that during demoulding, the part to be punched on the reserved section is torn and cracked, and the part to be punched is punched out after the demoulding of the cassette product is completed, thereby improving the yield rate of the cassette product and solving the problem that the end of the cassette product directly contacts the insert during demoulding and removal, which is easy to be torn and cracked, and has a low yield rate.
