[0002] In the actual processing of automobile filter housing, refer to Figure 1 As shown, the semi-finished housing 100 obtained by stretching has flash 200, which needs to be processed by a mold. In the actual processing of oil filter housings, the shapes of automotive filter housings are similar, and many housings only differ in diameter. However, in the existing technology, traditional molds for housings of different diameters require multiple complete sets of molds to process the flash of various sizes of housings, which leads to increased mold costs and low processing efficiency. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model proposes a flash mold for an automobile filter housing with quickly replaced cutouts. It can realize the flash of multiple housings by quickly replacing the cutouts under a set of mold architecture, thereby improving efficiency and saving mold costs.

[0004] In order to realize the above technical solution, the utility model provides a flash mold for automobile filter housing with which the notch can be quickly replaced, comprising: a flash upper mold and a flash lower mold, the flash lower mold comprising a lower mold notch, a lower base plate, a lower mold frame, a lower mold notch positioning block, a lower mold stripping block and a housing positioning block, wherein the lower base plate is fixed on the lower mold frame, the lower mold notch positioning block is fixed on the lower base plate, the lower mold notch is sleeved on the lower mold notch positioning block, the lower mold stripping block is sleeved on the outer side of the lower mold notch and the lower mold notch The top of the die protrudes upward to the top of the lower die stripping block, the shell positioning block is fixed at the top center of the lower die notch, the flash upper die includes an upper die frame, an upper base plate, an upper die stripping block, an upper die notch positioning block and an upper die notch, the upper base plate is fixed to the bottom of the upper die frame, the upper die stripping block is installed at the bottom of the upper base plate, the upper die notch positioning block is fixed to the bottom of the upper die stripping block, the upper die notch is fixed to the bottom of the upper die notch positioning block by screws, and the upper die notch is downwardly arranged facing the shell positioning block.

[0005] In the above technical solution, during actual operation, the semi-finished shell that needs to be flashed is placed on the shell positioning block of the flash lower die, and is punched down by the flash upper die. Under the action of the force of the punch press, the upper die cut is pressed downward, and the shell flash is punched and sheared in cooperation with the upper die cut and the lower die cut to complete the flashing operation. After the flashing operation is completed, the upper die stripping block, under the action of the internal spring, pushes out the shell after the flash is completed. This mold design adopts a design that can quickly replace the cut. By setting the lower die cut positioning block at the flash lower die, since the lower die cut is directly connected to the lower die cut positioning block, the lower die stripping block is directly connected to the outside of the lower die cut. Therefore, when it is necessary to process shells of different specifications, it is only necessary to remove the lower die stripping block from the lower die cut, and then remove the lower die cut from the lower die cut positioning block, and directly replace the lower die cut of different specifications. Similarly, the flash upper die is designed with an upper die notch positioning block, and the upper die notch is fixed to the bottom of the upper die notch positioning block by screws. When the upper die notch of different specifications needs to be replaced, only the screws need to be removed to quickly replace the same die with upper die notches of different specifications. The above structural design can achieve the flash punching and shearing of multiple shells of different specifications by quickly replacing the upper die notch and the lower die notch under a set of mold structure (this can be done on a stamping machine without disassembling the upper and lower mold frames by replacing key accessories such as the notch), thereby improving efficiency, saving mold materials, and saving manufacturing costs.

[0006] Preferably, a guide sleeve arranged vertically downward is installed on the upper mold frame, and a guide column matching the guide sleeve is arranged vertically upward on the lower mold frame. By arranging the guide sleeve and the guide column, it can be ensured that the downward stamping can be guided correctly to prevent the stamping from being offset.

[0007] Preferably, the lower die frame is fixed on the base plate of the machine tool, and the upper die frame is fixed on the punch head of the machine tool. During actual operation, the lower die frame is fixed, and the upper die frame moves up and down driven by the punch head of the machine tool.

[0008] The utility model provides a quick-change notch flash mold for automobile filter housings, which has the beneficial effect that: the quick-change notch flash mold for automobile filter housings has a simple structure and a reasonable design, and can realize the flash of multiple housings by quickly changing the notch under a set of mold structures, thereby improving efficiency and saving mold costs. The mold design adopts a quick-change notch design, by providing a lower mold notch positioning block at the flash lower mold. Since the lower mold notch is directly sleeved on the lower mold notch positioning block, and the lower mold stripping block is directly sleeved on the outer side of the lower mold notch, when it is necessary to process housings of different specifications, it is only necessary to remove the lower mold stripping block from the lower mold notch, and then remove the lower mold notch from the lower mold notch positioning block, and directly replace the lower mold notch of different specifications. Similarly, the flash upper die is designed with an upper die notch positioning block, and the upper die notch is fixed to the bottom of the upper die notch positioning block by screws. When the upper die notch of different specifications needs to be replaced, only the screws need to be removed to quickly replace the same die with upper die notches of different specifications. The above structural design can achieve the flash punching and shearing of multiple shells of different specifications by quickly replacing the upper die notch and the lower die notch under a set of mold structure (this can be done on a stamping machine without disassembling the upper and lower mold frames by replacing key accessories such as the notch), thereby improving efficiency, saving mold materials, and saving manufacturing costs.
