[0025] See also Figures 1 to 5The utility model provides a technical solution: an injection mold for parts production, comprising: an upper mold base 1 and a lower mold base 2, a mounting groove 3 is provided at the top of the lower mold base 2, a mold 4 is installed inside the mounting groove 3, a clamping block 5 is fixedly installed at the bottom end of the mold 4, and one end of the clamping block 5 is connected to a protrusion 7; a clamping groove 6 is provided on the inner bottom wall of the mounting groove 3 near the clamping block 5, a plurality of protrusions 7 are provided and symmetrically installed at both ends of the clamping block 5, and a groove 8 is correspondingly provided on the inner side wall of the clamping groove 6 near each protrusion 7, so that the clamping block 5 can be inserted into the clamping groove 6 along the groove 8, thereby limiting the clamping block 5.
[0026] One end of the clamping block 5 is provided with a fixing groove 10, to which a fixing rod 9 is connected. A connecting rod 11 is mounted on one end of the fixing rod 9. One end of the connecting rod 11 passes through the lower die base 2 and extends out of the lower die base 2. One end of the connecting rod 11 is fixedly connected to the fixing rod 9, and the other end of the connecting rod 11 passes through the lower die base 2 and is fixedly connected to a pull ring 17, which facilitates pulling the pull ring 17 to drive the fixing rod 9 to move. Two guide blocks 18 are symmetrically mounted on the outer wall of the end of the fixing rod 9 near the connecting rod 11. A contraction groove 13 is connected to the inner wall of the clamping groove 6 near the end of the fixing rod 9. A guide groove 19 is provided on the inner wall of the contraction groove 13 near the two guide blocks 18 to facilitate guiding the fixing rod 9 and the connecting rod 11, making them less likely to rotate during movement.
[0027] A reinforcement groove 14 and a removal groove 15 are provided on the outer wall of the end of the connecting rod 11 away from the fixed rod 9, and a limit pin 16 is installed on the top of the lower mold base 2 near the reinforcement groove 14. A spring 12 is sleeved on the outer side of the end of the connecting rod 11 near the fixed rod 9. One end of the spring 12 is fixedly connected to the fixed rod 9, and the other end of the spring 12 is fixedly installed on the inner wall of the contraction groove 13. When the fixed rod 9 is inserted into the fixed groove 10, the spring 12 is in a compressed state, which is convenient for strengthening the fixing effect of the clamping block 5. The bottom end of the limit pin 16 passes through the lower mold base 2 and slides into the reinforcement groove 14. The reinforcement groove 14 and the removal groove 15 are provided on the outer wall of the top end of the connecting rod 11, and the removal groove 15 is located on the side of the reinforcement groove 14 near the fixed rod 9, which is convenient for fixing and disassembling the clamping block 5.
[0028] When the device is working, the clamping block 5 is installed at the bottom end of the mold 4, and a protrusion 7 is installed on the side wall of the clamping block 5, which is convenient for inserting the clamping block 5 into the clamping groove 6 along the groove 8, so that the mold 4 is not easily offset in the installation groove 3, and the fixing groove 10 is opened at one end of the clamping block 5, so that the fixing rod 9 is inserted into the fixing groove 10, which is convenient for fixing the clamping block 5. At this time, the spring 12 is in a compressed state, which is convenient for strengthening the fixing effect of the clamping block 5. By inserting the limit pin 16 into the reinforcement groove 14, the connecting rod 11 is not easy to move, thereby strengthening the fixing effect of the clamping block 5. The guide hole 18 installed on the outer wall of the rod is convenient for guiding the fixed rod 9, so that the movable rod 11 and the fixed rod 9 are not easily rotated during the movement, so that the reinforcement groove 14 and the removal groove 15 are always facing upwards. By pulling out the limit pin 16 and pulling the pull ring 17, the fixed rod 9 leaves the fixed groove 10. At this time, the limit pin 16 is inserted into the removal groove 15 to prevent the fixed rod 9 from moving toward the fixed groove 10 under the elastic action of the spring 12, thereby facilitating the disassembly of the mold 4, solving the problem of needing to remove multiple bolts when disassembling and installing the mold 4, the operation is more labor-saving, and the disassembly and assembly time is shorter.
[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
