Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0031] like Figures 1 to 6As shown together, the utility model provides a stripping mechanism for a press machine, including a solid seat 1, a concave cavity 2 is opened on the top of the solid seat 1, a solid block 6 is fixedly installed at the middle position inside the concave cavity 2, a pressing mold 5 is installed on the top of the solid block 6, a lifting drive 3 is fixedly installed inside the concave cavity 2, a wrapping frame 4 is fixedly connected to the movable end of the lifting drive 3, and the pressing mold 5 is located in the inner cavity of the wrapping frame 4, and the wrapping frame 4 completely wraps the pressing mold 5. When the press machine presses down on the mold cavity, the pressure on the side of the pressing mold 5 will be directly blocked by the wrapping frame 4 to prevent the side of the pressing mold 5 from being pushed outward due to excessive pressure;

[0032] The pressing mold 5 includes a bottom plate 51, side baffles 52 are rotatably mounted on both sides of the bottom plate 51, side baffles 53 are rotatably mounted on the front and rear sides of the bottom plate 51, and a mold cavity is formed between the bottom plate 51, the two side baffles 1 52 and the two side baffles 2 53.

[0033] According to a stripping mechanism for a press machine according to an embodiment of the utility model, a linear motor 32 drives the wrapping frame 4 to move upward, and pushes the two side baffles 1 52 and the two side baffles 2 53 to rotate in the direction of the bottom plate 51. The bottom plate 51, the two side baffles 1 52 and the two side baffles 2 53 form a mold cavity, and the material is placed in the mold cavity, and is pressed down by the downward pressing end of the press machine to form. When the pressing is completed, the linear motor 32 shortens and drives the wrapping frame 4 to move downward, and the wrapping frame 4 releases the limit on the two side baffles 1 52 and the side baffle 2 53, and rotates it in the direction away from the bottom plate 51, so that the side baffles 1 52 and the side baffle 2 53 are directly separated from the contact between the mold wall, so that the mold is exposed to the outside world, which is convenient for taking out the formed molded mold.

[0034] like Figure 1 to Figure 2As shown together, in this embodiment, the lifting drive 3 includes two linear motors 32, and the two linear motors 32 are installed on both sides of the concave cavity 2 in an opposite state. At the same time, the movable ends of the linear motors 32 are connected to the sides of the wrapping frame 4, and the linear motors 32 drive the wrapping frame 4 to move upward, pushing the two side baffles 1 52 and the two side baffles 2 53 to rotate in the direction of the bottom plate 51. When the wrapping frame 4 wraps the side baffles 1 52 and the side baffles 2 53 in all directions, the side baffles 1 52 and the side baffles 2 53 are restricted to be in a vertically straight state, and the two side baffles 1 52 The four sides of the bottom plate 51 are wrapped with the two side baffles 53. At this time, the bottom plate 51, the two side baffles 1 52 and the two side baffles 2 53 form a mold cavity. The material is placed in the mold cavity and pressed down by the downward pressing end of the press. When the pressing is completed, the linear motor 32 shortens and drives the wrapping frame 4 to move downward. The wrapping frame 4 releases the limit on the two side baffles 1 52 and the side baffle 2 53, and rotates it away from the bottom plate 51, so that the side baffles 1 52 and the side baffle 2 53 are directly separated from the contact between the wall of the module, so that the module is exposed to the outside world, which is convenient for taking out the formed module.

[0035] like Figure 1 to Figure 2 As shown together, in the present embodiment, two limit slides 31 are installed at the four sides of the concave cavity 2, limit guide blocks 33 are welded at the four sides of the wrapping frame 4, and a sliding cavity slidably connected to the limit guide blocks 33 is opened on the top of the limit slide 31, so as to limit the position of the wrapping frame 4, so that it can only be lifted and lowered vertically, and its position is ensured not to be offset when subjected to force.

[0036] like Figures 3 to 6 As shown together, in this embodiment, a rotating chamber 522 is opened at the bottom of the side baffle 52, and a rotating shaft 523 is rotatably installed inside the rotating chamber 522 through a bearing, and rotating blocks 524 are rotatably installed at both ends of the outer wall of the rotating shaft 523, and the rotating block 524 is welded to the side end of the bottom plate 51.

[0037] like Figures 3 to 6 As shown together, in this embodiment, a rotating chamber 532 is opened at the bottom of the side baffle plate 53, and a rotating shaft 533 is rotatably installed inside the rotating chamber 532 through a bearing, and rotating blocks 534 are rotatably installed at both ends of the outer wall of the rotating shaft 533, and the rotating blocks 534 are welded to the bottom plate 51.

[0038] like Figures 4 to 5As shown together, in this embodiment, magnet strip 1 511 is embedded and installed on both sides of the bottom plate 51, and magnet strip 2 525 is embedded and installed on the side of the side baffle 1 52 close to the bottom plate 51, and the opposite surfaces of magnet strip 1 511 and magnet strip 2 525 are in a state of magnetic repulsion. When the two side baffles 1 52 and the two side baffles 2 53 are combined together, magnet strip 1 511 and magnet strip 2 525 are also placed in a relative state. When the wrapping frame 4 releases the limit of the side baffles 1 52 and the side baffles 2 53, in the state of magnetic repulsion between magnet strip 2 525 and magnet strip 1 511, the two side baffles 1 52 will be pushed outward, so that the side baffles 1 52 will be out of contact with the mold parts.

[0039] like Figure 5 to Figure 6 As shown together, in the present embodiment, the front and rear sides of the side baffle plate 1 52 are both inlaid with magnet plates 1 521, and the opposite sides of the two side baffle plates 2 53 are both inlaid with magnet plates 2 531, and the opposite surfaces of the magnet plates 1 521 and 2 531 on the same side are in a state of magnetic repulsion. When the two side baffle plates 1 52 and the two side baffle plates 2 53 are combined together, the magnet plates 1 521 and 2 531 are placed in a relative state. When the wrapping frame 4 releases the limiting of the side baffle plates 1 52 and 2 53, the magnetic repulsion between the magnet plates 1 521 and 2 531 will push the two side baffle plates 2 53 outward, and the self-driving side baffle plates 2 53 rotate outward and separate from the mold parts.

[0040] When taking material from the mold, the two side baffles 1 52 and the two side baffles 2 53 are driven by magnetic repulsion to rotate outward and separate from the mold. There is no need to manually drive the side baffles 1 52 and the side baffles 2 53 to rotate, which is simple and convenient.
