[0016] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0017] In an embodiment of the present utility model, Figure 1 This is a structural schematic diagram provided according to the specific structure of a mold position rapid correction structure of the utility model. Figure 1 As shown, the utility model specifically includes: a positioning push-pull rod 4, a mold frame 1, a mold core 8, and an equipment bed slide block 6.

[0018] Wherein, the mold frame 1 and the equipment bed slide block 6 are positioned by a positioning structure, such as Figure 2 As shown, a guide groove 41 is provided on the positioning push-pull rod 4 along the length direction, one end of the positioning push-pull rod 4 is fixed to the mold frame 1, and the guide groove 41 is sleeved on the positioning drive rotation center 5.

[0019] Specifically, the positioning structure includes a mold handle 11 and a bed positioning hole 61 . The mold handle 11 is arranged on the top of the mold frame 1 . The equipment bed slider 6 is provided with a bed positioning hole 61 . The mold handle 11 is placed in the bed positioning hole 61 .

[0020] The specific fixing method of the positioning push-pull rod 4 and the mold frame 1 is as follows: a push-pull rod positioning hole 42 is provided at one end of the positioning push-pull rod 4, and a first mold frame positioning hole 12 is provided on the mold frame 1. The push-pull rod positioning hole 42 and the first mold frame positioning hole 12 are positioned by a mold frame positioning pin 3. The positioning push-pull rod 4 is fixed to the mold frame 1 by a screw 2.

[0021] First, pre-install the mold frame 1 on the work surface of the equipment bed, and align the mold handle on the mold frame with the positioning hole on the equipment bed slider to position the mold frame and the equipment bed slider. Insert the guide groove of the positioning push-pull rod 4 into the positioning drive rotation center 5, and the other end of the positioning push-pull rod 4 is positioned with the mold frame 1 through the mold frame positioning pin 3. After positioning, it is fixed with screws 2. By moving the positioning drive rotation center 5 back and forth radially, the position of the mold frame 1 is aligned. After correction, the mold frame 1 and the equipment bed slider 6 are fixed with bolts 7. After correction, remove the push-pull rod 4, mold frame positioning pin 3, and screws 2.

[0022] like Figure 3 As shown, the mold core 8 is positioned with the mold frame 1 by a mold core locating pin 9, the upper mold 81 of the mold core 8 is provided with an upper mold locating hole, and the lower mold 82 of the mold core 8 is provided with a lower mold locating hole (not shown in the figure), and the upper mold center locating hole and the lower mold center locating hole are positioned by a mold pin 10.

[0023] The mold core 8 is provided with a mold core positioning hole, the mold frame 1 is provided with a second mold frame positioning hole, and the upper mold positioning hole and the second mold frame positioning hole are positioned by a mold core positioning pin 9 .

[0024] Correction of the position of the mold frame and the mold center: After correcting the position of the upper mold of the mold center and the mold frame through the mold center locating pin, fix the upper mold of the mold center and the mold frame with bolts; then close the upper mold and the lower mold of the mold center, and use the mold pin to correct the concave and convex mold gap in the upper and lower molds of the mold center. After correction, fix the lower mold of the mold center and the mold frame with bolts, and remove the mold pin.

[0025] The positioning push-pull rod of the utility model is provided with a guide groove and a positioning pin hole. The guide groove on the push-pull rod is inserted into the positioning drive rotation center. The position of the push-pull rod center and the mold frame is ensured by positioning the pins. The push-pull rod and the mold frame are fixed, and the positioning drive mode of the radial sliding device is performed back and forth, thereby correcting the mold frame center and the equipment rotation positioning drive center. The mold frame and the mold core are positioned by the mold core positioning pins. The position of the pin holes on the mold core and the mold frame components is ensured by the machining process, thereby correcting the position of the mold frame and the mold core by the mold core positioning pins. The installation dimensions of the mold pins are unified, which is convenient for the universalization of the mold frame. When replacing the mold, only the mold core needs to be disassembled. At the same time, the die and the punch on the mold core adopt a die pin structure design. The position of the pin holes on the die and the punch components is ensured by the machining process, thereby ensuring the uniformity of the gap between the die and the punch through the die pins.

[0026] Through the above structure, the positioning drive rotation center and the mold frame position correction, the mold frame and the mold center position correction, the mold center upper and lower concave and convex gap uniformity correction. In addition, when changing the mold, only the mold core needs to be replaced, so as to achieve fast mold change, flexible, convenient and simple operation, and the mold frame is universal, reducing the mold opening cost.

[0027] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
