The inner end of the slot 42 passes through the middle of the corresponding positioning hole 41, and the two sides of the slot 42 are connected to the inner limit groove 43 formed on the inner side wall of the middle part of the positioning hole 41. The top of the push rod of the large oil cylinder 30 is screwed with a limit rod, and the end of the limit rod is formed with a limit block 31. The limit block 31 is in the fixed position. In the positioning hole 41, a small cylinder 50 is installed in the middle of the side wall corresponding to the movable mold frame 10, and a slider 51 is installed on the push rod of the small cylinder 50. The slider 51 is inserted into the slot 42, and the two sides of the slider 51 are inserted into the corresponding inner limit groove 43. The limit rod is inserted into the positioning groove 511 formed in the middle of the inner side wall of the slider 51, the bottom surface of the edge of the limit block 31 is pressed against the top surface of the slider 51, and the bottom surface of the edge of the slider 51 is pressed against the bottom surface of the inner limit groove 43.

[0028] Furthermore, two movable mold frame oil cylinder fixing grooves 11 are formed on the side wall of the movable mold frame 10 , and the large oil cylinder 30 is inserted into the movable mold frame oil cylinder fixing grooves 11 and fixed on the inner wall surface of the movable mold frame oil cylinder fixing grooves 11 .

[0029] Furthermore, the diameter of the limit block 31 is greater than the diameter of the push rod of the large oil cylinder 30 .

[0030] Furthermore, a connecting portion 44 is formed on the inner wall surface of the locking seat 40, and the connecting portion 44 is inserted into the fixed mold frame cylinder fixing groove 21 formed on the corresponding side wall of the static mold frame 20, and the locking seat 40 is fixed on the corresponding side wall of the static mold frame 20.

[0031] Furthermore, two fixed mold frame cylinder fixing grooves 21 are formed on the corresponding side walls of the static mold frame 20, two small cylinder fixing seats 1 are fixed on the side walls of the static mold frame 20 between the two fixed mold frame cylinder fixing grooves 21, the small cylinder 50 is fixed on the corresponding small cylinder fixing seat 1, a slider fixing seat 52 is fixed on the push rod of the small cylinder 50, and a slider 51 is fixed on the slider fixing seat 52.

[0032] Furthermore, a guide rod 2 is fixed on the side wall of the locking seat 40 , and the guide rod 2 is inserted into a guide through hole formed on the corresponding slider fixing seat 52 .

[0033] Furthermore, a limiting transverse rod 53 is fixed on the slider fixing seat 52, two positioning blocks 54 are fixed on the limiting transverse rod 53, a travel switch 4 is fixed on the small oil cylinder 50, and the roller on the lever of the travel switch 4 is located between the corresponding two positioning blocks 54, and the roller rests on one of the positioning blocks 54.

[0034] Furthermore, two large oil cylinders 30 are installed on the front side wall, left side wall and right side wall of the movable mold frame 10, and corresponding locking seats 40 are installed on the front side wall, left side wall and right side wall of the static mold frame 20.

A guide sleeve is also fixed in the guide through hole, and the guide rod 2 is inserted into the guide sleeve.

[0036] Working principle: When in use, after the machine tool presses and locks the static mold frame 20 and the dynamic mold frame 10 into place, at this time, the end of the push rod of the large oil cylinder 30 and the limit block 31 are in the corresponding positioning hole 41 of the locking seat 40, and then, the push rod of the small oil cylinder 50 pushes, so that the slider 51 extends into the slot 42, and the two sides of the slider 51 are inserted into the corresponding inner limit groove 43 for locking. After the slider 51 moves into place, at this time, the roller on the lever of the travel switch 4 is moved by the corresponding positioning block 54 presses against and pushes, and is triggered, and the travel switch 4 transmits a signal to the machine tool. After receiving the signal, the machine tool controls the control valve of the hydraulic system, so that the push rod of the large oil cylinder 30 is pulled back, so that the edge bottom surface of the limit block 31 presses against the top surface of the slider 51, and the edge bottom surface of the slider 51 is close to the bottom surface of the inner limit groove 43, thereby ensuring that the static mold frame 20 and the dynamic mold frame 10 are pressed and locked more firmly, and the dynamic mold and static mold therein are further locked, thereby solving the mold flash problem, and the effect is very good. In the mold design process, the structure in this embodiment can be added to different molds according to design requirements. This design is suitable for all die-casting molds and plastic molds.
