A cooling pool 3 and two side plates 2 are fixed on the upper surface of the base 1. A push plate 4 is fixed on one side of one side plate 2. A mounting plate 5 is slidably matched on one side of the push plate 4. Another mounting plate 5 is fixed on one side of the other side plate 2. The right mold 6 and the left mold 7 are respectively fixed on one side of the two mounting plates 5. A group of buckle components 9 are fixed on one side of the right mold 6 and the left mold 7. A mounting groove is provided on one side of the mounting plate 5. 8. Buckle grooves 10 are provided on both groove walls of the mounting groove 8, and an inner groove 11 is provided on the bottom groove of the mounting groove 8. The buckle assembly 9 is located on the inner side of the mounting groove 8. The buckle assembly 9 includes a group of buckle plates 95. The buckle plates 95 are slidably fitted in the buckle grooves 10. A vertical plate 12 is slidably fitted in the inner groove 11. A group of extrusion plates 13 for extruding the buckle plates 95 is fixed on one side of the vertical plate 12, and a threaded screw 22 is rotatably connected to the other side of the vertical plate 12. The threaded screw 22 passes through the mounting plate 5 and is threadedly connected to the mounting plate 5.

[0024] A set of take-up plates 16 is fixed to one side of the right mold 6 , and a clearance groove 17 adapted to the take-up plates 16 is provided on the inner side of the left mold 7 .

[0025] Through the cooperation of the material taking plate 16 and the clearance groove 17, after the die-casting of the workpiece is completed, the material taking plate 16 will push the workpiece in the left mold 7 outward during the process of sliding outward in the clearance groove 17, so as to realize the automatic removal of the workpiece, and make the removed workpiece fall into the cooling pool 3, so as to realize the cooling treatment of the workpiece, accelerate the cooling speed of the workpiece, and avoid the workpiece from scalding the workers.

[0026] Among them, the buckle assembly 9 also includes a back plate 91, a partition plate 92 is fixed on one side of the back plate 91, two first guide rods 93 are fixed on the partition plate 92, a buckle plate 95 is slidably sleeved on the first guide rod 93, a first beveled surface 96 is provided on one side of the buckle plate 95, the two buckle plates 95 are symmetrically arranged relative to the partition plate 92, a plurality of tension springs 94 are fixed between the partition plate 92 and the buckle plate 95, the tension spring 94 surrounds the outside of the first guide rod 93, two second beveled surfaces 15 are opened on the extrusion plate 13, the second beveled surfaces 15 are in sliding contact with the first beveled surfaces 96, a knob is fixed at one end of the threaded screw 22, a strip groove 14 is opened on one side of the vertical plate 12, and one end of the partition 92 is slidably fitted in the strip groove 14.

[0027] The screw rod 22 can be easily turned by turning the knob, and the screw rod 22 can push the vertical plate 12 to move inside the inner groove 11, so that the extrusion plate 13 squeezes the buckle plate 95. After the buckle plate 95 is squeezed, the buckle plate 95 slides outward along the first guide rod 93, the tension spring 94 is stretched, and the buckle plate 95 slides into the inner side of the buckle groove 10. The partition plate 92 slides between the two extrusion plates 13 and enters the strip groove 14. The mounting plate 5 is fixedly connected to the right mold 6 and the left mold 7 through the buckle plate 95. When the mold needs to be replaced, it is only necessary to reversely screw the threaded screw 22 to make the extrusion plate 13 slide into the inner groove 11. After the buckle plate 95 loses the extrusion of the extrusion plate 13, under the elastic restoring force of the tension spring 94, the two buckle plates 95 will automatically slide out of the buckle groove 10. At this time, the buckle assembly 9 can be easily pulled out of the mounting groove 8, and the right mold 6 and the left mold 7 can be easily removed. The setting of the second bevel 15 and the first bevel 96 makes it easier for the extrusion plate 13 to squeeze the buckle plate 95.

[0028] Among them, a plurality of sliding rods 20 are fixed on one side of one of the mounting plates 5, and the pushing plate 4 is slidably sleeved on the outside of the sliding rod 20. A spring 21 is fixed between the pushing plate 4 and the mounting plate 5. A hydraulic cylinder 18 is fixedly installed on one side plate 2, and the output end of the hydraulic cylinder 18 is fixedly connected to the side of the pushing plate 4. A plurality of second guide rods 19 are fixed on one side of the pushing plate 4, and one end of the second guide rod 19 slides through the side plate 2.

[0029] The pushing plate 4 is pushed by the hydraulic cylinder 18 to move, so that the right mold 6 and the left mold 7 are close to each other and fit together. The setting of the spring 21 and the slide bar 20 plays a buffering role, slowly increasing the fitting pressure between the right mold 6 and the left mold 7, so that the right mold 6 and the left mold 7 are slowly fixed together, which plays a role in protecting the mold. The second guide rod 19 can make the pushing plate 4 move sideways stably, and the setting of the slide bar 20 can make the right mold 6 move sideways stably.

[0030] The working principle and use process of this utility model:

[0031] After the hydraulic cylinder 18 is started, the push plate 4 is connected to the right mold 6 and moves toward the left mold 7. During the process of the left mold 7 and the right mold 6 being tightly fitted, the spring 21 will be slowly squeezed, and the material taking plate 16 is located in the give way groove 17. Then, the solution is injected into the die-casting cavity formed by the left mold 7 and the right mold 6 through the injection port on the top of the left mold 7. When the die-casting is completed, the hydraulic cylinder 18 controls the push plate 4 to move outward, and the right mold 6 and the left mold 7 are separated. The material taking plate 16 pushes the workpiece in the left mold 7 outward, and the workpiece falls into the cooling pool 3 to achieve cooling treatment of the workpiece. When installing the right mold 6 and the left mold 7, it is only necessary to place the buckle assembly 9 on the inner side of the mounting groove 8, and screw the threaded screw 22 to move the vertical plate 12 inward, so that the right mold 6 and the left mold 7 can be fixed on the mounting plate 5. When disassembly is required, it is only necessary to screw the threaded screw 22 in the opposite direction to separate the right mold 6 and the left mold 7 from the mounting plate 5.
