The connecting rod moves to the left and pulls the rope to move to the left, and is limited by the turning column, and the baffle plate 1 is pulled to the right by the rope. The baffle plate 1 and the L-shaped push plate are coordinated with each other through the expansion and contraction of the spring plate, so that they move back and forth left and right, so that the baffle plate 1 blocks the mold plate that continues to feed on the conveyor belt to prevent the machine from welding and causing the mold plate to collide, resulting in damage to the mold plate and causing unnecessary losses.

[0007] Preferably, the fixing device includes a motor, a reciprocating screw, a movable plate, a connecting plate, a pushing plate 1, a spring telescopic column, a pushing plate 2, a sliding rod, a guide block, and a steering column.

The moving plate 1 moves left and right and drives the spring telescopic column to move left and right. The moving spring telescopic column moves left and right and drives the pushing plate 2 to move left and right and closer to the middle. , clamp and fix the mold plate to prevent the mold plate from being clamped not firmly enough, resulting in the welding point of the mold being offset during welding, so that the mold cannot be used normally after welding.

At the same time, the connecting plate moves left and right to drive the slide bar to move left and right, so that the slide bar contacts the guide block when it moves left and right, and the steering column is rotated through the internal slide groove of the guide block to make the steering column align the pushed mold plate, so that the welded part of the mold plate can be more convenient for machine welding.

Because the circumferential surface of the moving rod is provided with a non-self-locking spiral groove, when the limit block moves left and right and contacts with the non-self-locking spiral groove on the circumferential surface of the moving rod, a rotation is formed, so that the second baffle follows and rotates toward the bottom, so that the welding slag generated during the welding of the mold is blocked to prevent welding. The welding slag splashes, causing difficulties in subsequent cleaning. At the same time, it further prevents the high-temperature welding slag from scalding the operator during the splashing process, thereby playing a protective role. The scraper is slidably connected to the inner wall of the second baffle, and the arc plate is fixedly connected to the rear of the clamping device body; the rear of the scraper is slidably connected to the front of the arc plate, and the circumferential surface of the second baffle is in contact with the left side of the arc plate.

When the clamping device is started, the cylinder drives the L-shaped push plate to move left, so that the L-shaped push plate drives the connecting rod to move left when it moves left. When the conveyor belt transports the mold plate to the workbench, the L-shaped push plate will push the mold plate to the area to be welded, eliminating the step of manually carrying the mold plate to the workbench, while saving the time for welding the mold, and further improving the working efficiency of the machine. The connecting rod moves to the left and pulls the rope to move to the left, and is limited by the turning column. The baffle plate 1 is pulled to the right by the rope, and the baffle plate 1 is extended and retracted to cooperate with the L-shaped push plate to move back and forth, so that the baffle plate 1 blocks the mold plate that continues to feed on the conveyor belt to prevent the machine from welding and causing the mold plate to collide, resulting in damage to the mold plate and unnecessary losses.

[0011] 2. The welding clamping device for mold manufacturing operates through the cooperation among the motor, reciprocating screw, moving plate, connecting plate, pushing plate one, spring telescopic column, pushing plate two, sliding rod, guide block and steering column. When the clamping device is started, the reciprocating screw is driven to rotate by the motor, and the moving plate is moved left and right to the middle through the cross spiral groove on the reciprocating screw. The moving plate moves left and right to drive the connecting plate to move left and right, and the connecting plate moves left and right to drive the pushing plate one to move left and right. The pushing plate one moves left and right to drive the spring telescopic column to move left and right, and the spring telescopic column moves left and right to drive the pushing plate two to move left and right to the middle to clamp and fix the mold plate to prevent the mold plate from being clamped not firmly enough, resulting in the displacement of the welding point of the mold during welding, so that the mold cannot be used normally after welding. At the same time, the connecting plate moves left and right to drive the sliding rod to move left and right, so that the sliding rod contacts the guide block when it moves left and right, and is guided by the internal slide groove of the guide block to rotate the steering column, so that the steering column can straighten the pushed mold plate, so that the welding part of the mold plate can be more convenient for machine welding.

[0012] 3. The welding clamping device for mold manufacturing, through the coordinated operation among the limit block, the moving rod, the second baffle, the scraper, and the arc plate, drives the limit block to move left and right by pushing the first plate to move left and right. Because the circumferential surface of the moving rod is provided with a non-self-locking spiral groove, when the limit block moves left and right and contacts with the non-self-locking spiral groove on the circumferential surface of the moving rod, rotation is formed, so that the second baffle follows and rotates toward the bottom, so that the welding slag generated during the welding of the mold is blocked to prevent the welding slag from splashing during welding and causing difficulties in subsequent cleaning. At the same time, it further prevents the high-temperature welding slag from scalding the operator during the splashing process, thereby playing its protective role. When the second baffle follows and rotates toward the bottom, the scraper follows the second baffle to rotate toward the bottom, and at the same time, the scraper contacts with the arc plate when it rotates toward the bottom, and the arc plate guides the scraper to scrape the welding slag attached to the second baffle forward and backward.
