[0002] Headlights are tools for lighting the road at night and are also tools for issuing various driving signals. Headlights are generally divided into headlights, taillights, turn signals, etc. The combined headlights are at the front of the car, and they mainly play the role of lighting and signaling. The combined taillights are at the rear of the car, and they mainly play the role of lighting and signaling, and are used to indicate left or right turns to other road users. The license plate light is mainly used to illuminate the license plate, so that people can identify the vehicle license plate in the dark. When producing automobile headlight accessories molds, it is often necessary to use a mold opening machine to assist in production in order to improve the production efficiency of the mold.

The positioning slider 92 can be used to support and fix the position of the guide rod 94, so that the middle section of the guide rod 94 is in a suspended state, so that the connecting block 95 can pass smoothly.

[0025] Specifically, a limiting ring 97 is bolted to the surface of the forward and reverse threaded rod 93, a turntable 98 is fixedly connected to the side surface of the forward and reverse threaded rod 93, and a fixed block 99 is bolted to the upper surface of the guide rail 91. Through the turntable 98, the operator can control the rotation of the forward and reverse threaded rod 93, so that the forward and reverse threaded rod 93 can drive the connecting block 95 to move.

[0026] Specifically, there are two guide rails 91 , which are symmetrically arranged about the base 1 , and the connecting block 95 is threadedly connected to the surface of the positive and negative threaded rod 93 . There are two connecting blocks 95 , which are symmetrically arranged about the positive and negative threaded rod 93 .

[0027] In this embodiment, the guide rail 91 is used to guide the moving direction of the positioning slider 92, thereby reducing the problem of the positioning slider 92 being offset during movement.

[0028] Specifically, there are two limit rings 97, which are symmetrically arranged about the forward and reverse threaded rods 93. The fixing block 99 is plugged into the inner wall of the assembly groove. The side end of the guide rail 91 can be restricted by the fixing block 99, thereby constraining the maximum guide spacing of the guide rail 91.

[0029] In this embodiment: the auxiliary component 10 includes a buckle block 101, which is slidably connected to the surface of the guide rail 91, and a circular hole is provided on the side surface of the buckle block 101.

[0034] Working principle: When clamping the mold, place the mold seat on the side close to the ejector rod 8, and then rotate the turntable 98 in front. The rotation of the turntable 98 drives the positive and negative threaded rod 93 to rotate, and the positive and negative threaded rod 93 engages with the connecting blocks 95 on both sides. Under the action of the positive and negative threaded rod 93, the connecting blocks 95 on both sides drive the clamping plate 96 to move toward the mold. When the clamping plate 96 reaches the mold surface and is clamped, rotate the knob 105 on the rear clamping structure. The knob 105 is forced to rotate the bolt 104. The bolt 104 disengages from the limit hole 106 during the rotation and loses the constraint on the buckle block 101. When the buckle block 101 loses its constraint, push the turntable 98 at the rear, the turntable 98 pushes the positive and negative threaded rod 93, and the positive and negative threaded rod 93 pushes the positioning slider 92 When the parts move and the clamping plate 96 moves to the range of the movable mold, the operation of rotating the turntable 98 is repeated. The clamping plate 96 clamps the movable mold under the operation of the staff. Then when the equipment ejects the movable mold, the movable mold will pull the clamping plate 96. The clamping plate 96 pulls the connecting block 95 under force. The connecting block 95 pulls the positive and negative threaded rods 93. The positive and negative threaded rods 93 pull the positioning slider 92. The positioning slider 92 moves under the guidance of the guide rail 91 and guides the movable mold. By setting the clamping component 9 and the auxiliary component 10, the equipment can clamp the movable mold and the mold seat respectively, thereby reducing the problem that the equipment is difficult to clamp the movable mold, resulting in the displacement of the movable mold during the movement and causing damage, and further improving the stability and practicality of the mold opening machine.
