Description

Technical Field

[0001] The utility model relates to the technical field of thermoplastic plate product processing, in particular to an auxiliary tooling for thermoplastic plate product molding processing. Background Art

[0002] Thermoplastic composite sheets are made by laminating multiple layers of unidirectional tapes together at 0° / 90°. Continuous fibers can provide maximum strength and stiffness. The lamination method, thickness, reinforcement material type, and fiber volume content of the sheet can all be customized and processed into composite functional fabric core materials that meet the requirements. Thermoplastic composite sheets have excellent physical and mechanical properties.

[0003] When using thermoplastic plates to make different products, the thermoplastic plates must first be heated to a certain temperature and then quickly molded. The transfer time from the heating equipment to the molding equipment will greatly affect the molding quality of the product. Therefore, after being heated, the thermoplastic plates must be quickly transferred from the heating equipment to the compression molding hydraulic press for molding. The shape of the heated thermoplastic plates is relatively soft, and the thermoplastic plates are prone to sagging during the transfer process, thereby affecting the quality of the products after hot pressing. Therefore, an auxiliary tooling is designed to reduce the sagging of the thermoplastic plates during the transfer process and the impact on the quality of the molded products. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an auxiliary tooling for molding of thermoplastic plate products.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an auxiliary tooling for molding of thermoplastic plate products, including a frame, a mounting frame extending from a heating device toward a molding hydraulic press is fixed on the top of the frame, a sliding seat and a driving component for driving the sliding seat to reciprocate along the extension direction of the mounting frame are slidably mounted on the mounting frame, a vertical mounting seat is fixed on the sliding seat, a connecting frame and a lifting component for driving the connecting frame to rise and fall are slidably mounted on the vertical mounting seat, a rectangular frame is fixed on one side of the connecting frame away from the frame, and stretching components for grabbing and stretching the heated thermoplastic plate are arranged around the rectangular frame.

[0006] By adopting the above technical solution, the driving component can drive the sliding seat to reciprocate along the extension direction of the mounting frame, the vertical mounting seat is fixed on the sliding seat, and the lifting component drives the connecting frame to rise and fall along the vertical mounting seat, so that the connecting frame and the rectangular frame can move from the heating device toward the compression molding hydraulic press, so that the stretching component that grabs the heated thermoplastic plate moves from the heating device toward the compression molding hydraulic press, and the stretching component can stretch the heated thermoplastic plate outward, reducing the probability of the middle part of the thermoplastic plate sagging due to the relatively soft heated thermoplastic plate, which is beneficial to keep the heated thermoplastic plate in a tensioned state to a certain extent and improve the quality of the product after hot pressing.

[0007] Furthermore, the stretching assembly includes a base fixed to the bottom of the rectangular frame, a stretching motor fixed to the top of the base, a driving wheel fixed to the output shaft of the stretching motor, a screw rod rotatably installed on the base, a driven wheel fixedly sleeved on one end of the screw rod, a transmission belt for connecting the driven wheel and the driving wheel, a lower rail fixed to the bottom of the base, a movable block sleeved on the screw rod and threadedly connected to the screw rod, a side frame fixed to the movable block, a lower slider fixed to the top of the side frame and slidably matched with the lower rail, a connecting block arranged on the side frame, and a clamping cylinder fixed on the connecting block, wherein a plurality of the connecting blocks and the clamping cylinder are provided, and the clamping claw of the clamping cylinder extends toward a side close to the inside of the rectangular frame.

[0008] By adopting the above technical solution, after the stretching motor works, it drives the driving wheel to rotate, and the driven wheel rotates under the transmission action of the transmission belt, and drives the screw to rotate. Since the movable block is threadedly connected to the screw, the movable block and the side frame fixed on the movable block extend along the screw toward the side close to the inside of the rectangular frame. When the clamping claw cylinder grabs the edge of the heated thermoplastic plate, the stretching motor works in the reverse direction and drives the movable block, the side frame and the clamping claw cylinder to move in the reverse direction, and pulls the edge of the heated thermoplastic plate, so that the heated thermoplastic plate is kept in a tensioned state to a certain extent, reducing the probability of the middle part of the thermoplastic plate sagging due to the relatively soft heated thermoplastic plate.

[0009] Furthermore, the side frame is provided with an adjusting assembly for driving the connecting block to extend toward a side close to or away from the inside of the rectangular frame, the adjusting assembly includes an adjusting cylinder fixed to a side of the side frame away from the inside of the rectangular frame, a connecting plate fixed to an end of a piston rod of the adjusting cylinder, and a guide rod fixed to a side of the connecting plate close to the side frame, an end of the guide rod away from the connecting plate passes through the side frame and is slidably matched with the side frame, and the end of the guide rod is fixed to the connecting block.

[0010] By adopting the above technical solution, when the gripper cylinder grabs the edge of the heated thermoplastic plate, the adjustment cylinder works and drives the connecting plate to move toward the side away from the inside of the rectangular frame. The connecting plate drives the connecting block to move through the guide rod, so that the gripper cylinder on the connecting block moves toward the side away from the center of the rectangular frame, which is conducive to the gripper cylinder tightening the edge of the heated thermoplastic plate.

[0011] Furthermore, the lifting assembly includes a lifting motor fixed on the side wall of the vertical mounting seat, a lifting gear fixed to the end of the output shaft of the lifting motor, a lifting rack fixed on the connecting frame and meshing with the lifting gear, and a vertical slide rail fixed on the vertical mounting seat and slidingly matched with the connecting frame.

[0012] By adopting the above technical solution, the lifting motor drives the lifting gear to rotate after it starts working. Since the lifting gear is meshed with the lifting rack, the lifting rack is fixed on the connecting frame, and the connecting frame is slidably installed on the vertical mounting seat, so that the connecting frame can be lifted and lowered in the vertical direction, thereby driving the rectangular frame fixed on the connecting frame to lift and lower vertically, so that the clamping cylinder after grabbing the thermoplastic plate can be lowered to the thermoplastic plate molding hydraulic press for molding processing.

[0013] Furthermore, the driving assembly includes a driving motor fixed to the top of the sliding seat, a helical gear fixed to the output shaft of the driving motor, and a helical rack fixed to the top of the mounting frame and meshing with the helical gear.

[0014] By adopting the above technical solution, the driving motor drives the bevel gear to rotate after it starts working. Since the bevel gear is engaged with the bevel rack, and the bevel rack is fixed to the top of the mounting frame, the sliding seat can slide along the mounting frame from the heating device toward the compression molding hydraulic press, so as to move the thermoplastic plate from the heating device to the compression molding hydraulic press.

[0015] Furthermore, a transverse slide rail is fixed on the top of the mounting frame, and an upper slide block slidably matched with the transverse slide rail is fixed on the bottom of the sliding seat.

[0016] By adopting the above technical solution, the upper sliding block and the transverse sliding rail are slidably matched, thereby enhancing the stability of the sliding seat during the sliding process along the mounting frame.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The present application reduces the probability of sagging in the middle of the thermoplastic plate due to the softness of the heated thermoplastic plate, which is beneficial to keep the heated thermoplastic plate in a tensioned state to a certain extent and improve the quality of the product after hot pressing;

[0019] 2. In the present application, after the stretching motor works, it drives the driving wheel to rotate, and the driven wheel rotates under the transmission action of the transmission belt, and drives the screw to rotate. Since the movable block is threadedly connected to the screw, the movable block and the side frame fixed on the movable block extend along the screw toward the side close to the inside of the rectangular frame. When the clamping claw cylinder grabs the edge of the heated thermoplastic plate, the stretching motor works in the reverse direction and drives the movable block, the side frame and the clamping claw cylinder to move in the reverse direction, and pulls the edge of the heated thermoplastic plate, so that the heated thermoplastic plate is kept in a certain tension state, reducing the probability of the middle part of the thermoplastic plate sagging due to the relatively soft heated thermoplastic plate;

[0020] 3. In the present application, after the gripper cylinder grasps the edge of the heated thermoplastic plate, the adjustment cylinder works and drives the connecting plate to move toward the side away from the inside of the rectangular frame. The connecting plate drives the connecting block to move through the guide rod, thereby causing the gripper cylinder on the connecting block to move toward the side away from the center of the rectangular frame, which is beneficial for the gripper cylinder to tighten the edge of the heated thermoplastic plate.
