[0008] In an embodiment of the utility model, the bottom die is fixedly installed on the bottom plate, and the bottom die is a convex die.

[0009] In an embodiment of the utility model, the stamping driving part is a cylinder, the cylinder body is hingedly connected to the top plate, and the piston rod of the cylinder extends below the top plate.

[0010] In an embodiment of the utility model, the upper die comprises a connecting plate and a concave die.

[0011] One end of the connecting plate is hingedly connected to the support frame, and the concave die is fixedly installed at the bottom of the connecting plate away from the support frame. The concave die is located directly above the convex die.

[0012] The piston rod of the cylinder is hingedly connected to the connecting plate.

[0013] In one embodiment of the present invention, a positioning elastic sheet is provided inside the cavity mold, and a groove for accommodating the positioning elastic sheet is provided on the inner wall of the cavity mold.

[0014] In one embodiment of this utility model, the groove depth is equal to the thickness of the positioning elastic sheet.

[0015] This utility model also provides a PE board shaping machine, including the PE board bending fixture and a heating box as described above. The PE board bending fixture is fixedly installed on the top of the heating box. The heating box is provided with a heating chamber for heating the PE board. A sealing door for sealing the heating chamber is hinged to the heating box.

[0016] As described above, the PE board bending fixture and shaping machine of this utility model have the following beneficial effects:

[0017] 1. The heating box is used to heat the PE sheet to give it a certain plastic deformation ability. Then, the heated PE sheet is placed on the bottom mold. When the stamping drive drives the upper mold to press down on the PE sheet on the bottom mold, the stamping drive is hinged to the frame, and the upper mold is hinged to the moving end of the stamping drive and the frame.
