[0007] Preferably, rollers are rotatably sleeved on both sides of the mounting block, and sliding grooves for the rollers to slide are provided on the outer walls of both sides of the pressure plate.

[0008] Preferably, a through hole is formed on the top of the pressing plate.

[0009] Preferably, a pair of mounting ears are fixedly mounted at a central position on the top of the limiting plate, and the bottom of the second bolt is rotatably connected to the mounting ears.

[0010] Preferably, the corner connections of the mounting block are all rounded for smooth transition.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model clamps and fixes the mold in two directions through the cooperation of the pressure plate, the mounting block, the rotating plate and the limit plate. Compared with the method of only longitudinally fixing the mold by the pressure plate in the prior art, the utility model effectively improves the stability of the automobile mold during processing, reduces the risk of the mold loosening and being damaged, thereby improving the product processing quality.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a car mold pressing plate structure, including a pressing plate 1, a slider 3, a first bolt 4 and a mounting block 2 slidably mounted on the pressing plate 1. In the present application, the slider 3 is slidably mounted on the machine tool, and the mounting block 2 and the pressing plate 1 are pressed downward by locking the nut on the first bolt 4 to fix the mold above the machine tool. A through hole is provided on the top of the pressing plate 1, and the first bolt 4 is set through the through hole. The corners of the mounting block 2 are all rounded and smoothly transitioned. The advantage of this arrangement is that the sharp corners can avoid scratching the skin, and the mounting block 2 Rollers 9 are rotatably sleeved on both sides, and the rollers 9 are made of rubber. The purpose of this arrangement is to reduce the wear between the rollers 9 and the pressure plate 1. The outer walls of both sides of the pressure plate 1 are provided with sliding grooves 5 for the rollers 9 to slide. A rotating plate 6 is rotatably installed at the bottom of the mounting block 2. The rotating plate 6 is a U-shaped structure. The two ends of the rotating plate 6 extend to the two sides of the mounting block 2 for rotational connection. A wave section is provided on the side wall of the rotating plate 6. The top of the mounting block 2 is movably installed with a limit plate 8 through a second bolt 7. A pair of mounting ears are fixedly installed at the central position of the top of the limit plate 8. The bottom of the second bolt 7 is rotatably connected to the mounting ear, and the two ends of the top of the limiting plate 8 are respectively provided with protrusions 10 adapted to the wave section, so that the second bolt 7 can be screwed to drive the limiting plate 8 to contact the wave section of the rotating plate 6 and complete the angle limit of the rotating plate 6. During assembly, firstly, the pressing plate 1 is slid on the machine tool to adjust the distance according to the width of the mold, and then the end of the pressing plate 1 is placed on the top of the mold edge, and then the mounting block 2 is slid in the through hole, and one side of the rotating plate 6 is parallel to the side of the mold, and then the nut on the second bolt 7 is screwed to make the protrusion 10 of the limiting plate 8 and the rotating plate 6 parallel to the side of the mold. The wave section on the side wall of the movable plate 6 is in conflict, and the limit plate 8 provides an upward pulling force through the second bolt 7, so that the rotating plate 6 is pressed against the side of the mold, and then the nut on the first bolt 4 is tightened to make the mounting block 2 and the pressure plate 1 press the mold to complete the clamping and fixing of the mold. The present application clamps and fixes the mold in both directions through the cooperation of the pressure plate 1, the mounting block 2, the rotating plate 6 and the limit plate 8. Compared with the prior art method of only fixing the pressure plate longitudinally, the present application effectively improves the stability of the automobile mold during processing, reduces the risk of the mold loosening and being damaged, and thus improves the product processing quality.
