detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to the figure, in the embodiment of the utility model, a fixture for mold production includes a base 1, a screw rod 2, a fixed table 3 and a movable table 4; the base 1 is fixed on the processing equipment by screws, and the fixed table 3 is fixed Set on the left end of the base 1, the movable table 4 is slidably arranged on the base 1, and is arranged opposite to the fixed table 3, and the first rubber pad 12 and the second rubber pad 12 are respectively arranged on the opposite side of the fixed table 3 and the movable table 4. Pad 13, the thickness of the first rubber pad 12 and the second rubber pad 13 is 10-15mm, and a pressure sensor 14 is installed inside the first rubber pad 12, which can check the pressure after extrusion; the inside of the base 1 is set There is a horizontal inner cavity 16, and a screw mandrel 2 is horizontally arranged in the inner cavity 16, and the screw mandrel 2 is sheathed with an internally threaded nut 5 that is threaded, and the upper end of the internally threaded nut 5 is fixed on the movable platform 4. The upper surface of the base 1 corresponding to the threaded nut 5 is provided with a groove body, which is convenient for the movable table 4 to move; The screw mandrel 2 is driven to rotate, and a clamping device is provided above the corresponding gear 8.
