[0015] Both sides of the lower die base 10 are provided with fixing grooves 13 , and the centers of the two opposite sides of the two fixing movable plates 14 respectively pass through the interiors of the two fixing grooves 13 and are engaged with the fixing grooves 13 .

[0016] Two positioning grooves 11 are provided inside the lower mold base 2 at the center position corresponding to the bottom of the mounting groove 9. Positioning strips 12 are fixedly connected to both sides of the bottom of the lower mold base 10. The bottom of the positioning strip 12 passes through the interior of the positioning groove 11 and is clamped with the positioning groove 11.

[0017] The tops of the four supporting slide bars 3 are fixedly connected to the top plate 4, the center of the top of the top plate 4 is fixedly connected to the cylinder 6, and the output end of the bottom of the cylinder 6 passes through the interior of the top plate 4 and is fixedly connected to the top of the lifting plate 5.

[0018] An output end of one side of the variable frequency motor 15 passes through the interior of the groove 16 and is fixedly connected to the threaded rotating rod 20 .

[0019] Slots 22 are provided on both sides of the bottom of the upper die seat 7 , and clamping plates 23 are fixedly connected to both sides of the top of the upper die seat 8 . The top of the clamping plate 23 passes through the interior of the slot 22 and is clamped with the slot 22 .

[0020] A limiting groove 24 is provided in the center of the opposite side of the two clamping plates 23, and a cylinder 25 is fixedly installed on both sides of the bottom position in the upper mold top seat 7. The output ends of the two cylinders 25 on the opposite side are fixedly connected to the limiting rod 26, and the limiting rod 26 extends from the side of the cylinder 2 25 to the interior of the limiting groove 24 and is clamped with the limiting groove 24.

[0022] Working principle: Place the lower die base 10 in the installation groove 9, ensure that the positioning bar 12 at the bottom of the lower die base 10 is accurately aligned and engaged with the positioning groove 11 in the lower die base 2 to achieve the initial positioning of the lower die base 10, start the frequency conversion motor 15, and its output end drives the threaded rotating rod 20 to rotate in the groove 16. Since the threaded rotating rod 20 is threadedly connected to the movable plate 18, the movable plate 18 will move axially along the threaded rotating rod 20. The movement of the movable plate 18 drives the fixed movable plate 14 to move toward the center in the installation groove 9 through the connecting rod 19 until the central part of the fixed movable plate 14 penetrates and enters the fixed grooves 13 on both sides of the lower mold base 10, thereby achieving a firm clamping of the lower mold base 10. The cylinder 1 6 is started, and its bottom output end pushes the lifting plate 5 and the upper mold top seat 7 to slide downward along the supporting slide rod 3 until the upper mold base 8 is in close contact with the lower mold base 10, completing the mold closing action. At this time, the card groove 22 at the bottom of the upper mold top seat 7 and the card plate 23 at the top of the upper mold base 8 penetrate and clamp each other, further enhancing the stability of the mold closing. During the mold closing process or after the mold closing, the cylinder 2 25 is started, and its output end pushes the limit rod 26 to move toward the card plate 23. The limiting rod 26 penetrates into the limiting groove 24 at the center of the card plate 23 to further fix the card plate 23 and prevent the card plate 23 from being separated from the card groove 22 due to pressure during the injection molding process. After the mold is closed, the injection molding machine injects the molten plastic into the mold cavity. After the plastic is cooled and solidified, the mold is ready to be opened. The cylinder 25 contracts first to disengage the limiting rod 26 from the limiting groove 24; then the cylinder 1 6 contracts, driving the lifting plate 5 and the upper mold top seat 7 to rise to realize mold opening. At this time, the injection molded product can be taken out, and the frequency conversion motor 15 reverses, driving the threaded rotating rod 20 to rotate in the opposite direction, so that the movable plate 18 and the fixed movable plate 14 move to both sides of the installation groove 9, reset to the initial state, and prepare for the next installation of the lower mold base 10.

[0023] In summary: The hot-pressing injection mold for the production of automotive interior decoration, by setting a groove 16 in the lower mold base 2 and installing a frequency conversion motor 15 to drive the threaded rotating rod 20 to rotate, driving the movable plate 18 and the fixed movable plate 14 on the connecting rod 19 to slide in the installation groove 9, realizes the precise clamping and fixation of the lower mold base 10. This design enables the mold to quickly adapt to lower mold bases 10 of different sizes without the need to frequently replace the entire lower mold base 10, which significantly improves the flexibility and adaptability of the mold. The cylinder 16 is used to drive the lifting plate 5 and the upper mold top base 7 to perform lifting and lowering movements. Combined with the clamping design of the upper mold base 8, the clamping plate 23, and the clamping groove 22, the stability and accuracy of the mold closing process are ensured. Through the precise control of the frequency conversion motor 15, the fixed movable plate 14 is quickly adjusted, which further shortens the time for mold replacement and adjustment and improves production efficiency. In addition, the additional cost and resource waste caused by frequent replacement of the lower mold base 10 are avoided. The positioning groove 11 in the lower mold base 2 cooperates with the positioning bar 12 at the bottom of the lower mold base 10 to ensure the accurate positioning of the lower mold base 10 during the installation process. At the same time, the fixed movable plate 14 is firmly connected with the lower mold base 10 by passing through the fixing groove 13, which further enhances the stability and reliability of the mold. This design effectively avoids product molding quality problems and dimensional deviations caused by inaccurate mold positioning or loose fixation.
