[0002] With the development of society, plastic products are being used more and more widely. When plastic products are produced and processed, they are mainly produced by injection molding. When assembling the injection mold with the injection molding machine, the injection mold is usually fixed on a stable base inside the injection molding machine.
[0003] A search revealed that publication number "CN216578927U" discloses a base for injection molds that is easy to disassemble and install, comprising a base, a movable block, a positioning pin, a cylinder, a guide pin, and a positioning pin; the base has positioning holes at all four corners for installation. In this injection mold, the cylinder drives the movable block to move on the guide pin, causing the positioning pin on the movable block to insert through a pin hole and connect with the hole on the positioning pin, thus tightly connecting the base to the positioning pin on the worktable. This completes the installation, and disassembly is convenient, requiring no bolts for fastening, and installation is quick.

[0018] Please see Figure 1-3 This utility model provides a technical solution for a stable base structure for injection molds:
[0019] according to Figure 1-3 As shown, the system includes a base 1 and an injection mold 2. Two fixing strips 3 are fixedly provided on the front of the base 1. The two fixing strips 3 are detachably fixedly connected to the bottom of the injection mold 2. Inverted T-shaped grooves 6 are provided at both corners on both sides of the base 1. Inverted T-shaped sliders 9 are slidably connected inside the inverted T-shaped grooves 6. An L-shaped pressure block 5 is fixedly installed on the top of the inverted T-shaped slider 9. The L-shaped pressure block 5 contacts the top of the injection mold 2. An electric push rod 7 is fixedly installed on one side of the inner wall of the inverted T-shaped groove 6. The telescopic end of the electric push rod 7 is fixedly connected to one side of the inverted T-shaped slider 9.
[0020] Specifically, the installation between the base 1 and the injection mold 2 is achieved by fixing the fixing strip 3 and the connecting strip 8. At the same time, the four L-shaped pressure blocks 5 press down on both sides of the injection mold 2, which effectively improves the stability of the assembly between the injection mold 2 and the base 1.
[0021] according to Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a stable base structure for an injection mold. The top of the fixing strip 3 is provided with a strip-shaped groove 11, and both sides of the strip-shaped groove 11 are threadedly connected with threaded rods 4. Both sides of the bottom end of the injection mold 2 are fixedly provided with connecting strips 8 that are adapted to the strip-shaped groove 11. Both ends of the connecting strip 8 are provided with threaded holes 10. The connecting strip 8 is embedded into the interior of the strip-shaped groove 11, and the threaded rods 4 are threadedly connected to the corresponding threaded holes 10.
[0022] Specifically, the threaded connection between the threaded rod 4 and the threaded hole 10 facilitates the fixing of the connecting strip 8 inside the strip groove 11, thereby achieving the connection between the base 1 and the injection mold 2.
[0023] according to Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a stable base structure for an injection mold. A support plate 15 is slidably connected to the side of the L-shaped pressure block 5. The top of the support plate 15 is in contact with the bottom of the injection mold 2. A limiting groove 16 is provided on the side of the L-shaped pressure block 5. The limiting groove 16 is convex. A limiting slider 13 is slidably connected inside the limiting groove 16. The limiting slider 13 is fixedly connected to the center of the side of the support plate 15.
[0024] A fixing rod 12 is fixedly installed between the top and bottom ends of the limiting slide groove 16. A through hole is opened in the middle of the limiting slider 13. The fixing rod 12 is inserted and connected to the through hole. A return spring 14 is nested at the bottom of the fixing rod 12. The bottom end of the return spring 14 is fixedly connected to the bottom end of the limiting slide groove 16 and the bottom of the limiting slide groove 16. The top end of the return spring 14 is fixedly connected to the bottom end of the limiting slider 13.
[0025] Specifically, the reset force of the reset spring 14 pushes the limit slider 13 to move upward. The upward movement of the limit slider 13 causes the support plate 15 to come into close contact with the bottom end of the injection mold 2. Through the cooperation of the support plate 15 and the L-shaped pressure block 5, the injection mold 2 is further limited and fixed.
[0026] The control switch for the electric push rod 7 is fixedly installed on the side of the base 1. The electric push rod 7 is electrically connected to an external power source through the control switch.
[0027] Working principle: This utility model discloses a stable base structure for an injection mold. When the base 1 is used to install the injection mold 2, firstly, the connecting strips 8 on both sides of the bottom end of the injection mold 2 are pressed into the strip-shaped groove 11 opened at the top of the fixing strip 3. Then, the threaded rods 4 at both ends of the fixing strip 3 are manually rotated to make the threaded rods 4 threadedly connected and fixed with the threaded holes 10. Next, the electric push rod 7 is turned on, and the inverted T-shaped slider 9 is moved by the electric push rod 7. The movement of the inverted T-shaped slider 9 drives the L-shaped pressure block 5 to move, so that the bottom of the L-shaped pressure block 5 contacts the top of the injection mold 2. At this time, the support plate 15 contacts the bottom end of the injection mold 2 through the pushing force of the return spring 14, which facilitates further limiting and fixing of the injection mold 2, and improves the stability of the assembly of the injection mold 2 and the base 1.
