[0034] Reference Figure 2-Figure 4The left side of the table body 1 is fixedly connected with a pneumatic device 17, and the right side of the pneumatic device 17 is fixedly connected with a plurality of limit columns 10. The pneumatic device 17 here is used to provide power and high-pressure gas. The outside of the limit column 10 is slidably connected to the left inner wall of the box body 6. The outside of the plurality of limit columns 10 is fixedly connected with a movable mold 9. The left side of the movable mold 9 contacts the left side of the inner wall of the box body 6. The box body 6 here provides a stable support for the movable mold 9. The outside of the plurality of limit columns 10 is slidably connected with a pressing plate 11. The right side of the pressing plate 11 contacts the left side of the fixed mold 5. The pressing plate 11 here is tightly fitted with the fixed mold 5. The right side of the movable mold 9 is rotatably connected with a plurality of support rods 12. Every two adjacent support rods 12 The other end is rotatably connected to a slider 13. When the pressure plate 11 is fitted with the fixed mold 5, the support rod 12 here will start to rotate, and the right side of the slider 13 is slidably connected to the left side of the pressure plate 11. The inner walls of the two sliders 13 are slidably connected to a long rod 14, and a spring 15 is sleeved on the outside of the long rod 14.

[0036] Working principle: First, the staff will grind the raw materials to be injected into powder and pour them into the hopper 2. At this time, the heat pipe 3 and the pushing device 4 can be started. The heat pipe 3 will start to transport the raw materials inside and perform hot melting operations on them, and the pushing device 4 here will push the heat pipe 3 to move to the left, and then the raw materials inside the heat pipe 3 will be poured into the fixed mold 5. At this time, the pneumatic device 17 can be started, and the pneumatic device 17 will push the movable mold 9 to move to the right. After the pressing plate 11 contacts the fixed mold 5, the limiting column 10 here will be inserted into the holes at the four corners of the fixed mold 5 to prevent it from falling off. At this time, the two sliders 13 begin to slide to both sides on the long rod 14, and the support rods 12 begin to rotate around their left axis points, thereby stretching the spring 15 to generate a reaction force, so that the pressing plate 11 and the fixed mold 5 are squeezed tighter to prevent the raw materials from overflowing during injection molding, thereby causing powder loss problems and improving the quality of the product.

[0037] At the same time, the cavity 20 will also extend into the hole in the center of the left side of the fixed mold 5. When the pressure plate 11 contacts the surface of the fixed mold 5, the gas delivery rod 18 can be controlled to drive the top box 19 to move to the right. When the top box 19 is completely moved into the hole, the pneumatic device 17 can be controlled to transmit compressed gas to the inside of the gas delivery rod 18. After the gas is transmitted to the cavity 20, the steel ball 21 and the limit plate 22 are squeezed outward, thereby completing the engagement with the fixed mold 5. This operation ensures the stability of the shell during injection molding.

[0038] During the injection molding process, the staff can observe the injection molding situation inside the box body 6 through the observation window 8 provided on the box door 7, thereby reducing the risk of accidents.
