[0028] In order to facilitate the understanding of the insert mold provided by the embodiments of the present application, first of all, the application scenario thereof will be described. At present, the single ear hinge is a key component for hoisting operation of large and medium-sized equipment in the engineering machinery industry, and therefore the performance requirements for the single ear hinge are strict, and it must be a forged product without any forging defects. However, there are many varieties of single ear hinges, and the forging is performed by using an 8000T friction press. The overall mold structure is used, and a mold needs to be designed and manufactured for each variety of single ear hinge. According to the calculation of the striking force of the 8000T equipment, the mold module size needs to be 700x800x350. The cost of a single mold is high, and once the mold is deformed or cracked, the entire mold will be scrapped, resulting in a sharp increase in manufacturing cost. In view of this, the present application provides an insert mold. By manufacturing a plurality of insert molds, a unified mold seat is used, the manufacturing cost is reduced, the replacement operation is simple and convenient, and high safety is ensured.

[0029] Reference should be made to Figure 1 , Figure 1It is a structure schematic view of the insert mold provided by the embodiment of the application; the insert mold comprises a lower mold base 100 and an upper mold base 200; in the application, the insert mold for single product manufacturing of diversified single ear hinges is installed and combined by using the unified upper mold base 200 and the lower mold base 100, so that the production cost is reduced while the high yield is ensured, and the overall disassembly is more convenient. Meanwhile, the steel material cost of the upper mold base 200 and the lower mold base 100 is lower than that of the insert mold, so that the service life of the insert mold is prolonged, and the damage of the single product insert mold does not affect the use of the upper mold base 200 and the lower mold base 100.

[0030] Specifically, the lower mold insert 120 is detachably fixed and assembled on the lower mold base 100, and the upper mold insert 220 matched with the lower mold insert 120 is detachably fixed and assembled on the upper mold base 200; in the application, the lower mold insert 120 is positioned along the side edge of the lower mold base 100, and the upper mold insert 220 is positioned along the side edge of the upper mold base 200, so that the high fitting degree is ensured, the overall replacement positioning is more convenient, and the rapid and efficient production is realized.

[0031] In addition, in the application, the lower pad 110 for supporting the lower mold insert 120 is assembled on the lower mold base 100; the upper pad 210 for supporting the upper mold insert 220 is assembled on the upper mold base 200; by the lower pad 110 and the upper pad 210, the pressure generated in the production process can be effectively transmitted to the lower mold base 100 and the upper mold base 200, so that the damage of the lower mold insert 120 and the upper mold insert 220 is reduced, thereby prolonging the service life.

[0032] In the application, in order to further control the production cost, the upper mold base 200 and the lower mold base 100 are both seat bodies made of 45 steel material. The production cost is reduced. The upper pad 210 and the lower pad 110 are both block bodies made of 45 steel material. The production cost is reduced. In the case of manufacturing multiple lower mold inserts 120 and upper mold inserts 220 for multiple single products, the lower mold insert 120 and the upper mold insert 220 are mold bodies made of die steel material. It has strong rigidity and prolongs the service life. As can be seen, the lower mold base 100 and the upper mold base 200 are both made of 45 steel material, which is 50% lower in cost than the previous die steel material, and the lower mold insert 120 and the upper mold insert 220 of multiple categories have a longer service life, which ensures the production quality. In addition, the first assembly groove structure matched with the lower pad 110 is formed on the lower mold base 100; the second assembly groove structure matched with the upper pad 210 is formed on the upper mold base 200. The detachable fixed connection relationship is realized. Through the setting of the lower pad 110 and the upper pad 210, the generated pressure support can be transmitted to the upper mold base 200 and the lower mold base 100, and the lower pad 110 or the upper pad 210 can be replaced in time after being damaged by pressure, so that the overall operation has high convenience.

[0033] Combining Figure 2 And Figure 3 As shown in the first limiting assembly for positioning the lower die insert 120 is arranged on the lower die seat 100; the second limiting assembly for positioning the upper die insert 220 is arranged on the upper die seat 200. The lower die insert 120 is positioned on the lower die seat 100 through the first limiting assembly, and the upper die insert 220 is positioned on the upper die seat 200 through the second limiting assembly.

[0034] Specifically, the overall size of the upper die insert 220 and the lower die insert 120 is consistent, which is different from the internal mold size, so as to realize diversified and rapid installation. The lower die assembly cavity 130 matched with the lower die insert 120 is arranged on the lower die seat 100; the upper die assembly cavity 230 matched with the upper die insert 220 is arranged on the upper die seat 200. The matching installation is more compact.

[0035] The first limiting assembly is a first inclined wedge 140 arranged at the first side top of the lower die assembly cavity 130; the second limiting assembly is a second inclined wedge 240 arranged at the first side bottom of the upper die assembly cavity 230. Precise positioning is realized, and overall disassembly and replacement is more convenient. The first inclined wedge 140 and the second inclined wedge 240 are mutually oriented and mirror image distributed. The first inclined wedge 140 is inclined toward the inner cavity of the lower die assembly cavity 130; the second inclined wedge 240 is inclined toward the inner cavity of the upper die assembly cavity 230. Mirror image distribution realizes the limiting installation of the upper die insert 220 and the lower die insert 120.

[0036] In this application, the lower die insert 120 on the lower die seat 100 and the upper die insert 220 on the upper die seat 200 are replaced more conveniently, the production of various products is replaced quickly, and the unified lower die seat 100 and upper die seat 200 are adopted, which can effectively reduce the production cost. During use, the damage of the upper die insert 220 or the lower die insert 120 does not affect the use of the upper die seat 200 and the lower die seat 100; at the same time, the upper die seat 200 and the lower die seat 100 bear a large pressure, thereby improving the service life of the upper die insert 220 and the lower die insert 120.
