Description

Technical Field

[0001] This utility model relates to the technical field of wax film splicing devices, specifically to wax mold splicing devices. Background Technology

[0002] In the process of making castings, wax models are a commonly used intermediate casting component. They are obtained by injecting wax into a mold and removing the mold after the wax cools. At this time, the wax model is basically the same size as the actual object. Then, the operators gradually make the casting by applying sand to the outside of the wax model, boiling the wax, pouring in molten iron and cooling it.

[0003] With the rapid development of industry and the increasing trend of customization, in the precision casting process of valve castings, situations often arise where wax molds need to be assembled to produce non-standard valves or to use other molds to produce different products. In such cases, the wax molds must be modified and assembled. The most common method is to place several standard wax molds together and assemble them to obtain a completely new non-standard wax mold. However, in current technology, there are generally no auxiliary devices to assist in this type of wax mold assembly. Operators still rely primarily on traditional manual methods, which results in slow assembly speed, extremely low work efficiency, difficulty in aligning the mating surfaces, inaccurate length control after assembly, high product error rate, and unstable product dimensions, seriously affecting product quality and increasing production costs. Utility Model Content

[0004] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a wax mold splicing device, which can effectively solve the problems in the existing technology.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a wax model splicing device, including a chassis, a rack fixed on the chassis, and a top cover disposed on the outside of the rack. An adjustment assembly is fixed to the top of the top cover. The adjustment assembly includes two sets of L-shaped plates and toothed blocks fitted inside the L-shaped plates. A deflection block is disposed at the bottom of each toothed block, and the bottom of the deflection block abuts against the tooth groove of the toothed block. The bottom of the deflection block is also fixedly connected to a connecting block. Multiple sets of adjustment assemblies are equidistantly arranged on the top of the top cover. A spring is fixed between the outer side of each set of deflection blocks and the L-shaped plate. The toothed blocks mesh with the rack. The connecting blocks are fixedly connected to each other via the outer side of a lifting ring. Multiple sets of toothed holes are opened in the middle of the top cover, and the rack is disposed within the toothed holes. A main rotating shaft is fixed to the middle of each toothed block, and a deflection shaft is fixed to the middle of each deflection block.

[0006] Furthermore, the dimensions of the toothed hole and the toothed rack are matched.

[0007] Furthermore, multiple sets of racks are fixedly arranged in an equidistant array on the chassis, the top of the top cover is fixedly connected to the pressure table, and the pressure table is a frustum-shaped structure that is larger at the top and smaller at the bottom.

[0008] Furthermore, the toothed holes and the adjusting components are positioned opposite each other, and two sets of springs are provided, symmetrically arranged on the outer side of the deflection shaft.

[0009] Furthermore, the outer side of each set of connecting blocks is fixedly connected to the lifting ring.

[0010] Furthermore, two sets of rotating holes are provided on the side wall of the L-shaped plate, and the main rotating shaft is disposed in the rotating holes of the two sets of L-shaped plates, and the deflection shaft is disposed in the other set of rotating holes.

[0011] Beneficial effects The technical solution provided by this utility model has the following advantages compared with the known public technology: This invention, through its adjustable component structure, allows the user to lift the ring structure upwards, thereby causing the connecting block to deflect and stretch the spring structure. This eliminates the locking effect between the connecting block and the toothed block structure, allowing the toothed block to rotate via the main shaft. Because the toothed block structure contacts the toothed structure of the rack, the top cover and the adjustable component move up and down. At this point, the wax film is placed on the chassis, and the top cover is lowered to the top of the wax film. Pressure is applied through the pressure table structure, ensuring high alignment of the wax mold mating surfaces, low product misalignment rate, and stable product dimensions.

[0012] In this device, the pressure platform structure at the top is a truncated cone structure that is larger at the top and smaller at the bottom. The user can contact the external pressing power source through this cone structure, press down on the top cover structure, and drive the toothed block structure to rotate. The toothed block structure contacts the front end of the deflection block through the tooth groove. The outer side of the deflection block rotates with the deflection shaft, driving the spring to compress and rebound. Therefore, it can be controlled to a specified position as the user presses down. It can be used for splicing wax films of different thicknesses, as well as splicing and pressing with different displacements, thus expanding the application effect of this device.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example: Wax mold assembly device, see attached document. Figure 1 - Appendix Figure 3 The system includes a chassis 1, a rack 2 fixed to the chassis 1, and a top cover 3 disposed on the outside of the rack 2. An adjustment assembly 4 is fixed to the top of the top cover 3. The adjustment assembly 4 includes two sets of L-shaped plates 41 and toothed blocks 42 fitted inside the L-shaped plates 41. A deflection block 43 is disposed at the bottom of each toothed block 42. The bottom of the deflection block 43 abuts against the tooth groove of the toothed block 42, and the bottom of the deflection block 43 is fixedly connected to a connecting block 431. The top of the top cover 3... Multiple sets of adjustment components 4 are fixed in an equidistant array, and a spring 46 is fixed between the outer side of each deflection block 43 and the L-shaped plate 41. The toothed block 42 meshes with the rack 2. The connecting blocks 431 are fixedly connected by the outer side of the lifting ring 47. Multiple sets of toothed holes 31 are opened in the middle of the top cover 3, and the rack 2 is set in the toothed hole 31. A main rotating shaft 45 is fixed in the middle of the toothed block 42, and a deflection shaft 44 is fixed in the middle of the deflection block 43. The dimensions of the toothed hole 31 and the rack 2 are compatible. Through the adjustment component 4, the user can lift the ring 47 upwards, thereby causing the connecting block 431 to deflect, which in turn stretches the spring 46, canceling the tooth groove locking effect between the connecting block 431 and the toothed block 42. The toothed block 42 can then rotate via the main shaft 45. Since the toothed block 42 contacts the toothed structure of the rack 2, the top cover 3 and the adjustment component 4 move up and down. At this time, the wax film is placed on the chassis 1, and the top cover 3 is lowered to the top of the wax film. Pressure is applied by the pressure table 5, ensuring high alignment of the wax mold mating surfaces, low product mis-molding rate, and stable product dimensions.

[0019] Multiple sets of racks 2 are fixedly arranged in an equidistant array on the chassis 1. The top of the top cover 3 is fixedly connected to the pressure table 5, and the pressure table 5 is a frustum-shaped structure with a larger top and a smaller bottom. The positions of the toothed holes 31 and the adjusting components 4 are opposite. Two sets of springs 46 are provided, and the outer sides of the deflection shafts 44 are symmetrically arranged. The outer side of each set of connecting blocks 431 is fixedly connected to the lifting rings 47. Two sets of rotating holes 411 are opened on the side wall of the L-shaped plate 41, and the main rotating shaft 45 is set in the rotating holes 411 of the two sets of L-shaped plates 41, and the deflection shaft 44 is set in the other set of rotating holes 411. In this device, the pressure platform 5 at the top is a frustum structure that is larger at the top and smaller at the bottom. The user can contact the external pressing power source through this frustum, press down the top cover 3 structure, and drive the toothed block 42 structure to rotate. The toothed block 42 structure contacts the front end of the deflection block 43 through the tooth groove. The outer side of the deflection block 43 rotates with the deflection shaft 44, which drives the spring 46 to compress and rebound. Therefore, it can be controlled to a specified position as the user presses down. It can be used for splicing wax films of different thicknesses and for splicing and pressing with different displacements, thus expanding the application effect of this device.

[0020] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
