Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides a titanium alloy injection mold that can be quickly disassembled and assembled, including two fixed plates 1 arranged on the left and right sides respectively. A positioning frame 2 is fixed on the opposite side of the fixed plate 1. A mold core 3 is installed on the positioning frame 2. The side of the mold core 3 that is far away from each other is located inside the positioning frame 2. The part of the mold core 3 located inside the positioning frame 2 protrudes forward and backward to form positioning ear plates 4. The positioning ear plates 4 are located inside the positioning frame 2. A plurality of positioning pins 5 are fixed on the positioning ear plates 4 at equal intervals. Positioning holes 6 are opened on the positioning frame 2 at positions that match the positioning pins 5. The positioning pins 5 extend into the positioning holes 6 to initially limit the mold core 3, ensuring that the mold core 3 will not move in the front-back, back-up, or down directions. When disassembling and assembling the mold core 3, only the mold core 3 needs to be moved, which improves the disassembly and assembly speed. A positioning component 7 is provided on the positioning frame 2 at a position corresponding to the mold core 3. By placing the stop bar 704 between the mold core 3 and the fixed plate 1, the position of the mold core 3 can be fixed to ensure that the mold core 3 will not move in the left-right direction, thus ensuring the stability of the mold core 3 when it is fixed.

[0026] Specifically, fixing holes 8 are provided at the four corners of the fixing plate 1, and the fixing plate 1 is fixed and installed at the four corners by fixing bolts.

[0027] Furthermore, a guide groove 9 is provided on the side of the mold core 3 that is far away from the guide groove 9. A guide strip 10 is fixed on the fixed plate 1 at the position corresponding to the guide groove 9. The guide strip 10 guides the mold core 3 when it is installed in the positioning frame 2, so that the positioning ear plate 4 side of the mold core 3 can smoothly enter the positioning frame 2.

[0028] Further, the positioning assembly 7 comprises a lead screw 701 arranged below the positioning frame 2, the lead screw 701 is provided with symmetrically arranged threads with opposite directions, the lead screw 701 is threadedly connected with two symmetrically arranged moving blocks 702 with opposite moving directions, the top of the moving block 702 is fixedly connected with a vertical rod 703, the vertical rod 703 is arranged at the front and back sides of the positioning frame 2, the vertical rod 703 is fixedly connected with two up and down corresponding arranged blocking rods 704, the blocking rod 704 extends into the fixed plate 1 and the mold core 3, the blocking rod 704 is driven to extend into the fixed plate 1 and the mold core 3 through the structure of the lead screw 701, so as to block the displacement of the mold core 3, so as to fix the position of the mold core 3.

[0029] It is worth noting that the bottom of the positioning frame 2 is fixedly connected with two front and back symmetrically arranged fixed blocks 705, the fixed block 705 is rotatably connected with the lead screw 701, one end of the lead screw 701 is fixedly connected with a handle 706, so as to facilitate the rotation of the lead screw 701.

[0030] It is worth noting that the front and back sides of the positioning frame 2 are provided with guide grooves 707 corresponding to the positions of the blocking rods 704, the blocking rods 704 pass through the guide grooves 707.

[0031] It is worth noting that the edges of the blocking rods 704 corresponding to the positioning lug plates 4 are all formed with inclined surfaces, so as to facilitate the extrusion of the blocking rods 704 into the fixed plate 1 and the mold core 3.

[0032] Working principle and process: when the mold core 3 is disassembled, the lead screw 701 is rotated through the handle 706, and then the moving block 702 drives the vertical rod 703 and the blocking rod 704 to move away from each other under the action of the thread, until the end of the blocking rod 704 is in the guide groove 707, the mold core 3 can be displaced, the positioning lug plate 4 can move in the inner cavity of the positioning frame 2, the positioning column 5 leaves the positioning hole 6, the guide slide 10 enters the guide sliding groove 9, and the mold core 3 moves upward, so that the mold core 3 can be disassembled, when the mold core 3 is installed, one side of the positioning lug plate 4 of the mold core 3 is inserted into the positioning frame 2 from top to bottom, the positioning column 5 is arranged corresponding to the position of the positioning hole 6, the handle 706 is rotated, and then the moving block 702 drives the vertical rod 703 and the blocking rod 704 to move close to each other, so that the blocking rod 704 is extruded into the fixed plate 1 and the mold core 3, in this process, the mold core 3 is pushed, so that the positioning column 5 extends into the positioning hole 6, so as to fix the mold core 3, compared with the traditional bolt connection, a large amount of disassembly and assembly time can be saved, which is beneficial to the use of titanium alloy injection mold.
