An existing mold structure with repeatable positioning includes an outer ring mold, an inner ring mold and a positioning pin. The outer ring mold is sleeved on the inner ring mold. The outer ring mold and the inner ring mold have an interference fit. A positioning pin hole is provided at the connection between the outer ring mold and the inner ring mold. The positioning pin is inserted into the positioning pin hole. When removing the mold, the high heat may easily cause burns to the staff. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a mold structure that can be repeatedly positioned, which has a simple structure, can be easily disassembled, and has a good positioning effect.

[0004] The technical solution is: a repeatedly positionable mold structure, including a lower mold, characterized in that a positioning groove is opened on the inner upper part of the lower mold; positioning lifting frame structures are respectively arranged on the left and right sides of the lower mold; and a disassembly upper mold structure is arranged on the upper part of the lower mold.

[0005] Preferably, the positioning lifting frame structure includes a fixing plate, the lower bolt of the fixing plate is installed with a lifting motor; a lifting screw is installed on the output shaft of the lifting motor; and a movable ear plate is threadedly connected to the outer upper part of the lifting screw.

[0006] Preferably, the removable upper mold structure includes an upper mold, the left and right sides of which are connected to movable ear plates; a positioning ring is provided at the lower part of the upper mold; feed ports are provided at the left and right sides of the upper part of the upper mold; and a handle is installed at the middle and upper part of the upper mold.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] When the utility model is in use, the lifting motor can be used to drive the lifting screw to rotate from the movable ear plate, thereby facilitating the disassembly of the height of the upper mold structure for adjustment, and avoiding the influence of high heat dissipation on the staff when the mold is opened for the first time.

[0009] In the utility model, after the movable ear plate is lifted to the highest position, it can play a positioning role and prevent the movable ear plate from falling off the lifting screw easily, and the upper mold can be lifted upward conveniently by using a tool to penetrate the handle.

[0015] The utility model is further described below in conjunction with the accompanying drawings:

[0016] Example:

[0017] As attached Figure 1 and attached Figure 2 As shown, the utility model provides a repeatedly positionable mold structure, including a lower mold 1, characterized in that a positioning groove 2 is opened on the inner upper part of the lower mold 1; a positioning lifting frame structure 3 is respectively arranged on the left and right sides of the lower mold 1; a disassembly upper mold structure 4 is arranged on the upper part of the lower mold 1; the positioning lifting frame structure 3 includes a fixed plate 31, and a lifting motor 32 is installed on the lower bolt of the fixed plate 31; a lifting screw 33 is installed on the output shaft of the lifting motor 32; a movable ear plate 34 is threadedly connected to the outer upper part of the lifting screw 33, and when in use, the lifting motor 32 can be used to drive the lifting screw 33 to rotate from the movable ear plate 34, so as to facilitate the adjustment of the height of the disassembly upper mold structure 4 and avoid the influence of high heat dissipation on the staff when the mold is opened for the first time.

[0018] As attached Figure 3 As shown, in the above embodiment, specifically, the removable upper mold structure 4 includes an upper mold 41, and the left and right sides of the upper mold 41 are connected to the movable ear plate 34; a positioning ring 42 is provided at the lower part of the upper mold 41; a feed port 43 is provided at the left and right sides of the upper part of the upper mold 41; a handle 44 is installed in the middle and upper part of the upper mold 41, and the positioning ring 42 is inserted into the positioning groove 2 to play a good positioning role.

[0019] In the above embodiment, specifically, the fixing plates 31 are installed on the left and right sides of the lower mold 1 .

[0020] In the above embodiment, specifically, the upper end of the lifting screw 33 is a cylindrical rod, which can play a positioning role after the movable ear plate 34 is lifted to the highest point, and prevent the movable ear plate 34 from easily falling off the lifting screw 33, and use a tool to penetrate the handle 44 to facilitate lifting the upper mold 41 upward.

[0021] In the above embodiment, specifically, the positioning ring 42 is inserted into the inner side of the positioning groove 2 .

[0022] How it works

[0023] During the operation of the utility model, the positioning ring 42 can be inserted into the inner side of the positioning groove 2 when in use. At this time, the raw material can be injected into the lower mold 1 and the upper mold 41 from the feed port 43. When the mold needs to be opened, the lifting motor 32 can be used to drive the lifting screw 33 to rotate from the movable ear plate 34, and the movable ear plate 34 can be input to the outer side of the cylindrical rod. Then the staff can use the tool to lift the upper mold 41 up and down through the handle 44.
