It mainly realizes the processing of the object's appearance by changing the physical state of the molded material.

[0003] The prior art patent publication number CN218361607U is a motor housing aluminum extrusion die. The above patent squeezes the spring by pulling the latch, so that the latch moves out of contact with the hydraulic cylinder. The rotating cover drives the clamping block into the slot to limit the latch. The above steps are repeated for the other set of latches. At this time, the upper die can be separated from the hydraulic cylinder. The above operation makes it easy to replace the upper die of the extrusion die to meet the processing requirements of different motor housings.

[0004] However, from a practical point of view, the lower mold is fixed on the device housing and cannot be moved flexibly. It is also located below the upper mold. As a result, before and after the aluminum profile is formed, manual work is required to take and place the profile below the upper mold. If the operation is not timely, the hands of the personnel can easily be crushed by the upper mold, causing irreversible damage, which is dangerous. Utility Model Content

The outer wall of the nut seat 8 is slidably connected to the inner wall of the sliding groove 6. One end of the screw rod 7 is rotatably connected to the inner wall of one side of the sliding groove 6, and the other end of the screw rod 7 rotates to pass through the base 1;

[0025] By installing the pushing mechanism, when the upper mold 3 completes the extrusion molding of the aluminum profile and separates from the lower mold 5, the screw rod 7 in the safety pushing mechanism rotates, and the nut seat 8 can slide on the inside of the sliding groove 6 by the threaded structure when the screw rod 7 rotates, carrying the lower mold 5 to slide directly under the upper mold 3, so that manual work can be carried out for taking and placing materials not directly under the lower mold 5, thereby improving the safety of taking and placing materials.

[0026] Further, refer to Figure 2As shown, it is worth noting that one end of the screw rod 7 located outside the base 1 is tightly sleeved with a driven gear 9, and a control rod 10 is provided between the two driven gears 9 and is vertically connected to the outer wall of the base 1. A driving gear 11 meshing with the driven gear 9 is tightly sleeved on the rod body of the control rod 10;

[0027] By turning the knob control rod 10, the driving gear 11 can be synchronously meshed with the driven gears 9 at the ends of the two screw rods 7, so that the two screw rods 7 can rotate synchronously, allowing the lower mold 5 to move smoothly.

[0028] Further, refer to Figure 3 As shown, it is worth noting that a punch mechanism is provided in the die cavity of the lower die 5, and a pressure supply member cooperating with the punch mechanism is provided on the inner side of the sliding groove 6;
