[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-2 As shown, this utility model embodiment provides a mold core fixing fixture for fixing a mold core 100, which includes a bracket 1, an adhesive support block 2 and a pressing component 3.

[0037] The adhesive support block 2 is mounted on the bracket 1, and the mold core 100 is mounted on the upper surface of the adhesive support block 2. Adhesive is applied between the mold core 100 and the upper surface of the adhesive support block 2. The pressing assembly 3 includes a pressing member 31 and a pressing block 32. The pressing block 32 is located on the side of the mold core 100 facing away from the adhesive support block 2. The pressing member 31 is connected to the bracket 1 and can move towards the pressing block 32 to press against it. By pressing against the pressing block 32, the pressing member 31 applies uniform pressure to the mold core 100, thereby allowing the mold core 100 to press against the adhesive support block 2.

[0038] The mold core fixing fixture can apply continuous and uniform pressure to the mold core 100, so that the mold core 100 and the bonding support block 2 are firmly bonded, avoiding the phenomenon of the mold core 100 tilting or falling off due to uneven manual pressing, and saving manpower and improving production efficiency.

[0039] Optionally, the upper surface of the adhesive support block 2 is provided with a plurality of protrusions 21. The plurality of protrusions 21 are evenly distributed around the axis of the adhesive support block 2 on the upper surface of the adhesive support block 2, and the plurality of protrusions 21 form grooves. The mold core 100 is supported on the protrusions 21, and the adhesive is disposed in the grooves. This structure facilitates the placement of the adhesive, and the upper surface of the adhesive support block 2 can accommodate sufficient adhesive, effectively preventing the adhesive from being squeezed out.

[0040] Furthermore, four protrusions 21 are provided, and the four protrusions 21 are evenly distributed around the axis of the adhesive support block 2 to form a cross-shaped groove. By forming a cross-shaped groove on the adhesive support block 2, the adhesive distribution is more uniform, and the bonding of the mold core 100 is more stable.

[0041] Optionally, the cross-section of the protrusion 21 is configured as a fan-shaped ring. This structure allows the center of the groove to hold more adhesive, further improving the bonding strength of the mold core 100.

[0042] Optionally, the bracket 1 includes a base plate 11 and a U-shaped frame 12. The adhesive support block 2 is disposed on the base plate 11, the U-shaped frame 12 is placed upside down on the base plate 11, and the pressing component 31 is connected to the crossbar of the U-shaped frame 12. The bracket 1 has a simple structure and is easy to process and assemble.

[0043] Optionally, the pressing component 31 includes a screw 311 and a rotating handle 312. The crossbar of the bracket 1 is provided with a threaded hole, and the screw 311 is screwed into the threaded hole. The rotating handle 312 is fixed to the screw 311. By rotating the rotating handle 312, the screw 311 can be driven to rotate, thereby enabling the screw 311 to move toward the pressing block 32 and press against the pressing block 32 to apply pressure to the pressing block 32. This structure is simple, and the pressure applied to the pressing block 32 can be adjusted when rotating the screw 311, making operation simple.

[0044] Optionally, the rotating handle 312 includes a rotating block 3121 and two nuts 3122. The rotating block 3121 is provided with a through hole, and the screw 311 passes through the through hole. The rotating block 3121 is located above the crossbar of the U-shaped frame 12. The two nuts 3122 are screwed to the screw 311 and press against the two sides of the rotating block 3121, so that the rotating block 3121 is fixed to the screw 311. This enables the rotating block 3121 to drive the screw 311 to rotate, making the rotation of the screw 311 convenient.

[0045] Optionally, such as Figure 3 As shown, the pressure block 32 is provided with a limiting hole 321 on the side away from the adhesive support block 2. The end of the screw 311 facing the pressure block 32 can be inserted into the limiting hole 321 and press against the bottom of the limiting hole 321, so that the screw 311 can press against the pressure block 32. This structure can prevent the pressure block 32 from being misaligned with the mold core 100 and improve stability.

[0046] In this embodiment, the pressure block 32 is provided with limit holes 321 on both sides facing away from and towards the adhesive support block 2, so that the pressure block 32 can be installed without distinguishing the direction, making it convenient to use.

[0047] Optionally, the adhesive support block 2 is connected to the base plate 11 by the first screw 4. The lower end face of the adhesive support block 2 is provided with a first threaded hole, and the bottom surface of the base plate 11 is provided with a first countersunk hole. The first screw 4 passes through the first countersunk hole and is screwed into the first threaded hole, so that the adhesive support block 2 is installed and fixed on the base plate 11.

[0048] Optionally, both vertical rods of the U-shaped frame 12 are connected to the base plate 11 by the second screws 5. Both vertical rods of the U-shaped frame 12 are provided with second countersunk holes. The base plate 11 is provided with two second threaded holes. The two second screws 5 are respectively inserted into the two second countersunk holes and screwed into the two second threaded holes, so that the U-shaped frame 12 is installed and fixed on the base plate 11.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
