Referring to fig. 1 to 4, a thermoforming mold having a movable carrier member according to a preferred embodiment of the present invention will be described in detail below. The thermoforming mould can make the material supporting part move in the horizontal direction, and the purpose of facilitating material taking is achieved by moving the material supporting part. The thermoforming mold comprises a mold body 10, a driving member 20 and a material supporting member 30.

The die body 10 includes a die frame 11 and a lower die holder 12. The lower die holder 12 is fixedly arranged on the die carrier 11, and a molding surface 101 is formed at the top of the lower die holder 12.

The driving member 20 is provided to the mold frame 11.

The material supporting part 30 includes a bending part 31 and a material supporting part 32. The bending member 31 is disposed at the output end of the driving member 20. The material holding part 32 is arranged on one side of the bending piece 31 far away from the driving piece 20 along the horizontal direction. When the driving part 20 moves to the farthest movable end, one side of the bending part 31, which is far away from the driving part, is close to the lower die holder 12, and the material supporting part 32 is located right above the forming surface 101 in parallel, so that the material supporting part 32 can support the material sheets. When the workpiece is molded through the lower die holder 12, the material supporting part 32 can support and position the material sheet, so that the molding of the workpiece is facilitated.

After the workpiece is machined, the workpiece needs to be taken out, at this time, the driving part 20 drives the material supporting part 30 to move, so that the material supporting part 30 is far away from the lower die holder 12, the workpiece can be taken out from the side face of the lower die holder 12, the purpose of taking out the workpiece conveniently is achieved, time is saved, and the machining period of the workpiece is shortened.

The bending member 31 includes a horizontal portion 311 and a vertical portion 312 which are vertically connected to each other, wherein an end of the horizontal portion 311 away from the vertical portion 312 is disposed at an output end of the driving member 20. The top of the vertical part 312 close to one side of the lower die holder 12 is provided with a chamfer.

Since the vertical portion 312 has an inclined slope, the inclined slope can guide the material sheet to fall on the material holding portion 32 in a correct state during the falling of the material sheet, and the material sheet is prevented from being jammed in the vertical portion 312 due to the inclination.

The thermoforming mould also comprises an auxiliary part 40. The auxiliary member 40 is fixed to the mold frame 11. The auxiliary member 40 forms a guide channel 401 along the direction of movement of the driving member 20. The horizontal portion 311 is fitted to the guide passage 401. When the driving element 20 drives the material supporting part 30 to move, the horizontal part 311 slides in the guide channel 401, so that the stability of the material supporting part 20 in the moving process is ensured, and the material supporting part 20 moves to the correct position.

The auxiliary member 40 includes a fixing member 41 and a guide member 42. The fixing member 41 is provided to the mold frame 11. The guiding element 42 is fixedly arranged on the top of the fixing element 41, and the guiding element 42 forms the guiding channel along the moving direction of the driving element 20.

The fixing member 41 is detachably provided to the mold frame 11. When the guide member 42 is worn, the fixing member 41 can be removed, so that the guide member 42 can be replaced.

The auxiliary member 40 includes at least one screw. The screw penetrates through the fixing member 41 and is fixedly connected with the mold frame 11, so that the purpose of disassembling the fixing member 41 is achieved.

The thermoforming mould further comprises a connecting piece 50. The connecting member 50 is configured to connect the horizontal portion 311 and the output end of the driving member 20, so that the horizontal portion 311 is detachably connected to the output end. If the material supporting part 30 has a problem and needs to be repaired or replaced, the connecting part 50 can be used for conveniently separating the material supporting part 30 from the output end of the driving part 20, so that the operation during disassembly is convenient.

Both ends of the connecting piece 50 are provided with external threads, the horizontal part 311 and the output end of the driving piece 20 are provided with internal thread grooves matched with the external threads, so that the connecting piece 50 can be detachably connected with the output end of the driving piece 20 and the horizontal part 311 to achieve the purpose of convenient disassembly.

The drive 20 is embodied as a cylinder. The mold frame 11 includes a support member. The support member is detachably provided to the mold frame 11. The cylinder is provided to the support. The supporting member can be detached from the mold frame 11 to change the distance from the cylinder to the mold frame 11 by replacing the supporting member with a different length, so that the distance from the material supporting member 30 to the molding surface 101 can be adjusted, and the material supporting portion 32 can support the material sheet with different heights.

The vertical portion 312 is provided with a mounting hole 301 in a direction parallel to the moving direction of the driving member 20. The material receiving portion 32 is adjustably disposed in the mounting hole 301.

The vertical portion 312 is provided with a plurality of positioning holes 302 communicating with the mounting hole 301. A plurality of positioning holes 302 are distributed in the vertical portion 312 along the vertical direction. The material supporting part 30 further comprises a rotation stopping rod 33. The rotation stopping rod 33 is disposed on the material supporting portion 32, the rotation stopping rod 33 is matched with the positioning hole 302, and the rotation stopping rod 33 may be rectangular or triangular. When the rotation-stopping rod 33 is inserted into the positioning hole 302, the material-holding portion 32 is fixed to the vertical portion 312. Since the vertical portion 312 is provided with a plurality of positioning holes 302, the rotation stop bar 33 is positioned inside different positioning holes 302, so that the position of the material supporting portion 32 on the vertical portion 312 can be adjusted, and the distance from the material sheet to the molding surface 101 is adjusted. Therefore, even if the thickness of the workpiece is too thick, the material sheet does not contact the workpiece when being positioned on the material supporting part 32, and the material supporting part 32 can stably receive the material sheet, so that different workpieces can be used for the hot forming die.

In a modified embodiment of the present invention, the material supporting portion 32 is rotatably close to or far from the lower die base 12, and when the material supporting portion 32 is close to the lower die base 12, the material supporting portion 32 is in a horizontal shape. The bending member 31 is rotatably disposed on the mold frame 11, and the driving member 20 is used for driving the bending member 31 to rotate on the mold frame 11. The drive 20 is still embodied as a cylinder. The output end of the cylinder is hinged with the bending piece 31, the bending piece 31 is also hinged with the die carrier 11, and when the output end of the cylinder moves to the maximum range, the material supporting part 32 is horizontally positioned above the forming surface 101.
