Description

Technical Field

[0001] The utility model relates to the technical field of precision casting, in particular to a wax piece module hanger for precision casting. Background Art

[0002] Precision casting refers to the general term for the process of obtaining castings with precise dimensions. Compared with the traditional sand casting process, the castings obtained by precision casting are more precise in size and have better surface finish. It includes: investment casting, ceramic casting, metal casting, pressure casting, and lost foam casting.

[0003] During the precision casting process, no matter the wax module is dipped in slurry or sprinkled with sand, the wax module is generally hoisted. The traditional method is to suspend it by passing a rope through a handle. Although this method can realize the hanging of the wax module, the wax module is very easy to swing, and in severe cases, it will cause collision damage to the wax module. In order to improve the stability of the hanging of the wax module, the wax module hoist in the prior art is to connect the wax module hoist rod equipped with the wax module to the lower end of the connecting sleeve of the hoist. The connection method generally adopts threaded connection or hook connection. However, the threaded connection method requires the staff to repeatedly perform the screwing operation, which has high labor intensity. Although the hook connection method improves the hanging efficiency, the hook will still produce displacement and sliding in the subsequent processing process, affecting the subsequent wax module processing and production effect.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0026] Please refer to the instruction manual Figure 1-5 , the utility model provides a technical solution:

[0027] Embodiment 1, a wax mold hanger for precision casting, comprising a hanger 1, and a handle 8 on the upper part of the wax mold, a hanging rod 6 perpendicular to the handle 8 is provided on the upper end of the handle 8, and both ends of the lower surface of the hanging rod 6 are fixedly connected to the upper ends of the handle 8 through connecting plates 7, respectively. The handle 8 is connected to the hanging rod 6 through two connecting plates 7, which not only facilitates the staff to carry the wax mold, but also ensures that the wax mold is located in the middle of the hanging rod 6 during the subsequent hanging process, providing strong support for the subsequent stable hanging;

[0028] A hanging hole 3 is provided on one side of the lower part of the rod body of the hanging rod 1, which penetrates the rod body of the hanging rod 1 and is used for hanging and clamping the hanging rod 6. An opening 5 for hanging and installing the hanging rod 6 is provided on the inner wall of one side of the hanging hole 3. In order to ensure that the hanging hole 3 can effectively clamp the hanging rod 6 stably, the width of the hanging hole 3 is adapted to the width of the hanging rod 6. In order to prevent the hanging rod 6 from detaching from the opening 5, the lower edge of the opening 5 is higher than the lower end surface of the inner cavity of the hanging hole 3;

[0029] In order to further limit and fix the hanging rod 6 in the hanging opening 3, a spring 2 arranged axially along the hanging rod 1 is provided on the upper end surface of the inner cavity of the hanging opening 3, and a pressing plate 4 for pressing and limiting the hanging rod 6 is provided at the lower end of the spring 2.

[0030] In the second embodiment, during the hanging process of the wax module, as the wax module rotates or moves, although the pressure plate 4 can press and limit the hanging rod 6, the hanging rod 6 may still be displaced and slide, thereby causing the wax module to tilt. In order to prevent the hanging rod 6 from sliding, a limiting ridge 12 is provided on the lower end surface of the inner cavity of the hanging port 3, and a limiting snap-in 9 is provided on the lower surface of the hanging rod 6 that matches the limiting ridge 12. Specifically, after the hanging rod 6 is inserted into the hanging port 3, the width of the hanging port 3 matches the width of the hanging rod 6, and the hanging rod 6 will not slide left and right. In order to prevent the hanging rod 6 from sliding back and forth along the axial direction of the hanging port 3, the limiting ridge 12 should be set perpendicular to the hanging rod 6. The limiting ridge 12 and the limiting snap-in 9 on the lower surface of the hanging rod 6 can effectively prevent the hanging rod 6 from sliding.

[0031] Embodiment three, during the assembly line processing of wax part modules, it is usually necessary to hang a large number of wax part modules. At this time, multiple suspension rods 1 are often installed in fixed positions. In order to achieve the positioning installation of the suspension rod 1, a mounting plate 11 is provided at the upper end of the suspension rod 1, and a mounting hole 10 is provided on the surface of the mounting plate 11. After the mounting plate 11 is fixedly installed by screws passing through the mounting holes 10, the positioning installation of the suspension rod 1 can be guaranteed.

[0032] Embodiment 4: During the mobile hanging operation of the wax component module, it is often necessary to move the suspension rod 1 to different positions of the hanger according to needs. In order to facilitate the mobile hanging of the suspension rod 1, a cross bar 13 perpendicular to the suspension rod 1 is provided at the upper end of the suspension rod 1. One end of the cross bar 13 is fixedly connected to the upper end of the suspension rod 1 through an inclined connecting rod 15. In order to ensure that the cross bar 13 can be firmly and stably hung on the hanger, a clamping plate 14 and a driving mechanism that drives the clamping plate 14 to slide and adjust along the axial direction of the cross bar 13 are provided on the lower surface of the cross bar 13. Specifically, a slide groove 19 arranged along the axial direction of the cross bar 13 is provided on the lower surface of the cross bar 13. The surface is provided with a sliding block 18 that slidably cooperates with the slide groove 19, and a screw rod 16 axially arranged in the eye slide groove 19 is rotatably installed in the slide groove 19. The screw rod 16 passes through the sliding block 18 and is threadedly cooperated with the sliding block 18. One end of the screw rod 16 passes through the slide groove 19, and a handle 17 is provided at its end. The screw rod 16 is rotated to rotate the handle 17, thereby driving the sliding block 18 to slide along the slide groove 19, and then driving the splint 14 to move. By adjusting the position of the splint 14 and utilizing the cooperation between the splint 14 and the connecting rod 15, the cross bar 13 can be fixedly suspended on the hanger, thereby ensuring the safety and stability of the subsequent wax module hanging.
