Description

Technical Field

[0001] The utility model relates to the technical field of wax injection equipment, in particular to a novel wax injection machine fixture lifting box. Background Art

[0002] The wax injection machine is a molding equipment for making wax molds. In the actual application of the wax injection machine, clamps of various specifications are transported to the clamping device, which clamps the mold and performs other operations, and then the wax injection nozzle of the wax injection device injects the molten liquid wax into the mold cavity. After it cools, the wax mold is taken out for subsequent processing operations; when the position of the clamp needs to be adjusted up and down, it is mainly driven by the lifting mechanism of the clamp to move the clamp up and down, but the existing lifting mechanism is not provided with a self-locking function. When the lifting mechanism clamp moves to the specified position, it is basically achieved by pin-connecting the transmission gear to achieve limit fixation. When adjustment is required later, the pin is pulled out to release the limit on the transmission gear, so that adjustment can be achieved. The lifting mechanism is locked by repeatedly inserting and pulling out the pin, which increases the wear of the transmission gear and causes the transmission gear to generate a large noise when the lifting mechanism is working, thereby affecting the normal use of the lifting mechanism and reducing the working accuracy of the lifting mechanism.

DETAILED DESCRIPTION

[0019] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0020] As attached Figure 1 、 2 As shown in Figures 3, 4, 5 and 6, the utility model provides a new type of wax injection machine fixture lifting box, including a box body 1, a transmission gear assembly 2 is arranged inside the box body 1, a rotating assembly 3 is arranged on one side of the box body 1, one end of the rotating assembly 3 extends into the box body 1 and is connected to the transmission gear assembly 2, a screw 4 is arranged at one end of the transmission gear assembly 2 away from the rotating assembly 3, one end of the screw 4 extends upward from the box body 1, and is provided with a threaded sleeve 5, and a self-locking module 6 is provided on the outer surface of the rotating assembly 3.

[0021] When the clamp is lifted or lowered: the user manually rotates the assembly 3, thereby driving the transmission gear assembly 2 to rotate by rotating the assembly 3. Subsequently, when the transmission gear assembly 2 rotates, it can further drive the screw rod 4 to rotate. Subsequently, the screw rod 4 is threadedly connected to the screw sleeve 5. When the screw rod 4 rotates, the screw sleeve 5 can be moved up and down by thread transmission. When the screw sleeve 5 moves up and down, it can drive the clamp fixed on the upper part of the screw sleeve 5 to move up and down, thereby realizing the lifting operation of the clamp;

[0022] Subsequently, when the rotating assembly 3 rotates to the specified position, the rotating assembly 3 can be quickly locked by the self-locking module 6, thereby preventing the screw 4 from reversing and avoiding the displacement of the sleeve 5, ensuring the normal use of the device. The use of the self-locking module 6 to lock the lifting box can reduce the wear on the transmission gear assembly 2, reduce the noise generated by the device during lifting operation, and improve the working accuracy and service life of the lifting mechanism.

[0023] Preferably, the screw sleeve 5 is a T-shaped structure. By using the T-shaped screw sleeve 5 to drive the lifting of the tool, the stability during lifting can be ensured, and the vertical accuracy of the screw sleeve 5 during operation can be improved to prevent lifting deviation.

[0024] As attached Figure 1 、 2 , 3, 4, 5 and 6, the rotating assembly 3 includes a knob 31 and a transmission shaft 32. The knob 31 is arranged on one side of the box body 1, and the transmission shaft 32 is arranged inside the box body 1. One end of the transmission shaft 32 extends out of the box body 1 and is connected to the knob 31, and the other end is rotatably arranged inside the box body 1. The outer surface of the transmission shaft 32 is provided with a transmission gear assembly 2;

[0025] The subsequent transmission gear assembly 2 includes a driving gear 21 and a driven gear 22. The driving gear 21 is arranged on the outer surface of the transmission shaft 32, and the driven gear 22 is arranged inside the box body 1. The driving gear 21 and the driven gear 22 are meshed with each other, and a screw 4 is arranged inside the driven gear 22.

[0026] When it is necessary to drive the screw 4 to rotate: by twisting the knob 31, the transmission shaft 32 can be driven to rotate, and the rotation of the transmission shaft 32 can drive the rotation of the driving gear 21. The driving gear 21 is engaged with the driven gear 22. When the driving gear 21 rotates, it can further drive the rotation of the driven gear 22. When the driven gear 22 rotates, it can synchronously drive the rotation of the screw 4.

[0027] It should be noted that the structures of the driving gear 21 and the driven gear 22 are consistent. The driving gear 21 and the driven gear 22 are spiral bevel gears. Using two sets of spiral bevel gears as transmission parts can ensure that the transmission gear assembly 2 has the advantages of stable transmission ratio and low noise during operation, and the transmission efficiency of the spiral bevel gear is the highest, so the stability and reliability of the transmission gear assembly 2 during operation can be guaranteed.

[0028] Subsequently, a locking groove 311 is formed on the outer surface of one end of the knob 31 close to the transmission shaft 32, and a self-locking module 6 is clamped on the outer surface of the locking groove 311. The self-locking module 6 includes a fixed block 61 and a clamping assembly 62. The fixed block 61 is sleeved on the outside of the locking groove 311, and a through hole 611 is provided inside the fixed block 61. The clamping assembly 62 is arranged inside the through hole 611, and the clamping end of the clamping assembly 62 faces the locking groove 311.

[0029] When the knob 31 of the rotating assembly 3 is rotated to a specified position, the clamping assembly 62 of the self-locking module 6 can be directly pressed against the locking groove 311, thereby locking the knob 31 and preventing the knob 31 from remaining in a stable state when not in operation, thereby preventing the screw from reversing and causing the T-shaped screw sleeve to move;

[0030] Subsequently, the clamping assembly 62 includes an adjusting screw 621 and a clamping bead 622. The adjusting screw 621 is arranged inside the through hole 611, and the clamping bead 622 is arranged at one end of the adjusting screw 621 close to the locking groove 311. The clamping bead 622 and the locking groove 311 abut against each other. A spring member 623 is arranged between the clamping bead 621 and the adjusting screw 621. One end of the spring member 623 abuts against the adjusting screw 621, and the other end abuts against the clamping bead 622.

[0031] When the knob 31 is locked: When the knob 31 is rotated to the designated position, the spring member 623 exerts its elastic force to push the bead 622 into the locking groove 311, thereby locking the knob 31.

[0032] When the knob 31 is subsequently unlocked, the knob 31 is rotated so that the bead 622 can be disengaged from the locking groove 311, thereby moving the bead 622 toward the adjusting screw 621 and compressing the spring member 623. Subsequently, when the knob 31 is rotated to the subsequent lifting position, the bead 622 can be directed toward the adjacent locking groove 311, which can eliminate the pressure on the bead 622 and release the compression of the spring member 623, so that the spring member 623 can push the bead 622 into the locking groove 311, thereby realizing continuous locking and releasing of the knob 31, which can improve the overall practicality of the lifting box.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
