Description

Technical Field

[0001] This utility model relates to the field of wax mold technology, specifically to a wax mold forming mold structure that facilitates demolding of handicrafts made using the wax mold method. Background Technology

[0002] Wax molding is a traditional craft technique that uses wax as raw material and molds to create the blank of a craft. It is widely used in metal casting, precision sculpture, and other fields. Its core principle is to inject molten wax into a specific mold cavity. After the wax cools and solidifies, it forms a wax model that matches the shape of the mold cavity. Subsequent processing (such as coating with refractory materials, dewaxing, and casting) is then carried out based on the wax model to obtain the finished craft. Due to the good fluidity and plasticity of wax, wax molding can accurately replicate the details of the mold, making it especially suitable for making crafts with complex shapes and intricate patterns. Therefore, it occupies an important position in craft production. As the key tool for wax molding, the structure design of the mold directly affects the molding accuracy, production efficiency, and ease of demolding. Therefore, special molds adapted to the characteristics of wax molding are needed to ensure the quality of the craft and the continuity of production.

[0003] Traditional wax molds for crafts typically employ a fixed structure, with a rigid connection between the mold cavity and the mold base. Demolding requires manual prying or striking of the mold, a method with significant drawbacks: firstly, rigid prying easily leads to edge damage and detail deformation of the wax mold, especially for thin-walled, hollow, or complexly patterned wax molds, resulting in a very high breakage rate and severely impacting the finished product's pass rate; secondly, manual demolding is cumbersome, consuming considerable manpower and time. Furthermore, as production batches increase, the inner wall of the mold cavity is prone to wear due to repeated friction, leading to a decrease in the dimensional accuracy of subsequent wax molds, further increasing the defect rate of the crafts and hindering the large-scale, efficient production of wax mold crafts. Therefore, we propose a wax mold structure that facilitates demolding. Utility Model Content

[0017] Compared with the prior art, this utility model provides a mold structure for wax modeling crafts that facilitates demolding, and has the following beneficial effects:

[0018] 1. This wax mold forming mold structure facilitates demolding. Through the cooperation of a sliding structure and mold components, flexible demolding is achieved. The mold cavity and mold are fixed inside a pressure plate that slides along a sliding rod. During demolding, simply moving the sliding rod via a turntable allows the mold and mold cavity to separate smoothly, avoiding damage to the wax mold from external impacts. The auxiliary components' adjustment and clamping structures enable automated clamping and rapid separation. Rotating the adjustment wheel drives the clamping rod synchronously via a connecting rod, quickly clamping and fixing the mold. During demolding, reversing the adjustment structure releases the clamp, and the sliding rod facilitates one-click separation. Multiple structural designs reduce mold wear. On one hand, the clamping block at the bottom of the clamping rod flexibly contacts and fixes the pressure plate, avoiding squeezing damage to the mold from rigid clamping. On the other hand, the sliding structure composed of the sliding rod and turntable ensures smooth and frictionless mold separation, reducing direct wear between the cavity and mold core. The round hole design of the wax injection port in the wax injection structure ensures uniform wax injection, preventing mold deformation caused by excessive local pressure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A mold structure for molding wax-based handicrafts that facilitates demolding, comprising:

[0026] The base plate 1, fixing plate 1 2, fixing plate 2 3 and top plate 14 are fixedly connected to the top of the base plate 1 by a set of vertical and parallel support feet 4. The fixing plate 1 2 and fixing plate 2 3 are parallel to each other. The side of the fixing plate 1 2 has a through hole. The top of the fixing plate 2 3 is rotatably connected to the top plate 14. The top plate 14 is L-shaped. The vertical end of the L-shaped top plate 14 is connected to the fixing plate 1 2.

[0027] The wax injection structure is located on the side of the fixing plate 12 and is located in the through hole on the side of the fixing plate 12.

[0028] The mold assembly is disposed between the first fixed plate 2 and the second fixed plate 3. The mold assembly includes an installation structure and a mold structure, with the mold structure disposed on top of the installation structure.

[0029] The auxiliary components are located at the top and include a fixing structure, an adjusting structure, and a clamping structure. The fixing structure is located at the center of the top of the top plate 14. The top of the vertical fixing structure is equipped with an adjusting structure, and the side of the adjusting structure is connected to a clamping structure.

[0030] Furthermore, the wax injection structure includes a wax injection mounting post 5 and a wax injection port 6. The wax injection mounting post 5 is fixedly installed in the through hole on the side of the fixing plate 2. The wax injection port 6 is fixedly connected inside the wax injection mounting post 5. A through round hole is opened on the side of the wax injection port 6. In the wax injection structure, the wax injection mounting post 5 not only serves to fix the wax injection port 6, but its tight fit with the through hole on the side of the fixing plate 2 can also prevent the wax material from leaking from the gap during the injection process, ensuring that all the wax material enters the cavity formed by the mold 13 and the mold cavity 12. The through round hole design on the side of the wax injection port 6, in addition to ensuring uniform wax injection, can also reduce the wax backflow phenomenon after the wax injection is completed, avoid the occurrence of voids or missing material inside the cavity, and improve the integrity of the wax model forming.

[0031] Furthermore, the installation structure includes a support plate 7 and an installation groove 8. The support plate 7 is fixedly connected to the fixing plates 2 and 3 on both sides by screws. The installation groove 8 is provided in the center of the top of the support plate 7. The installation groove 8 is provided with a sliding structure. The support plate 7 of the installation structure is fixed to the fixing plates 2 and 3 by screws. This detachable connection method makes it easy to replace the support plate 7 or adjust its installation position according to the size requirements of different crafts, which enhances the versatility of the mold. The size of the installation groove 8 is adapted to the turntable 9, which not only provides a stable rotation space for the turntable 9, but also restricts the lateral displacement of the turntable 9 through the groove wall, ensuring the linear accuracy of the sliding rod 10 when driving the pressure plate 11 to slide, and avoiding the deviation during the separation of the mold 13 and the mold cavity 12.

[0032] Furthermore, the sliding structure includes a turntable 9, a sliding rod 10, and a pressure plate 11. The turntable 9 is movably installed inside the mounting groove 8. A set of parallel sliding rods 10 are fixedly installed on the top of the turntable 9. A set of pressure plates 11, symmetrically distributed along the lateral axis, are slidably installed on the top of the sliding rods 10. The top of the pressure plates 11 is bent. The turntable 9 of the sliding structure is connected to the mounting groove 8 using high-precision bearings, making the rotation process smoother and less labor-intensive, reducing the intensity of manual operation. The surface of the sliding rods 10 is smoothed to reduce the frictional resistance between them and the pressure plates 11, ensuring the stability of the pressure plates 11 during sliding. Especially during the demolding stage, it can avoid uneven local force on the wax mold caused by jamming. The bent design of the top of the pressure plate 11, in addition to facilitating the clamping of the clamping rod 20, can also increase the contact area with the clamping blocks, disperse the clamping force, and prevent the pressure plate 11 from deforming during the clamping process.

[0033] Furthermore, the mold structure includes a mold cavity 12 and a mold 13. The mold 13 is fixedly installed inside the pressure plate 11 on the side near the fixed plate 2, and the mold cavity 12 is fixedly installed inside the pressure plate 11 on the side near the fixed plate 3. A model groove is opened on the side of the mold cavity 12. The mold 13 mates with the model groove on the side of the mold cavity 12. The edge of the model groove opened on the side of the mold cavity 12 of the mold structure adopts a rounded corner transition design, which can reduce stress concentration when the wax material cools and avoid cracks on the edge of the wax model. It can also reduce the risk of the wax model sticking to the cavity when demolding. The fitting gap between the mold 13 and the mold cavity 12 is precisely calculated to ensure the sealing when the two are closed and to reserve space for the slight shrinkage of the wax material after cooling, which facilitates the subsequent separation operation.

[0034] Furthermore, the fixing structure includes a second mounting groove 15 and a mounting block 16. The second mounting groove 15 is provided in the center of the top of the top plate 14. The mounting block 16 is connected inside the second mounting groove 15. The mounting block 16 is fixedly connected to the top plate 14 by a fixing pin 21. The inner wall of the second mounting groove 15 of the fixing structure is provided with a positioning protrusion, which cooperates with the groove on the side of the mounting block 16 to quickly achieve the positioning and installation of the mounting block 16, reducing the debugging time. The fixing pin 21 adopts an anti-loosening design. By increasing the friction between the pin and the mounting block 16 and the top plate 14, it prevents the connection from loosening due to vibration during long-term use, ensuring the stable operation of the adjustment structure and the clamping structure.

[0035] Furthermore, the adjustment structure includes an adjustment rod 17 and an adjustment wheel 18. The adjustment wheel 18 is rotatably mounted on the top of the mounting block 16. One end of the adjustment wheel 18 is rotatably connected to the mounting block 16, and the other end of the mounting block 16 is rotatably connected to the adjustment rod 17. The adjustment rod 17 is F-shaped, and the middle part of the adjustment rod 17 is movably connected to the mounting block 16 through a fixing pin 21. The adjustment rod 17 of the adjustment structure is F-shaped, and its two ends are connected to the adjustment wheel 18 and the mounting block 16 respectively, forming a force-saving lever structure. The operator only needs to apply a small force to drive the adjustment wheel 18 to rotate, which reduces the difficulty of operation. The surface of the adjustment wheel 18 is provided with anti-slip texture to increase the friction between the hand and the wheel body, avoid slippage during operation, and improve the safety and accuracy of operation.

[0036] Furthermore, the clamping structure includes a connecting rod 19 and clamping rods 20. The connecting rod 19 is Y-shaped, and one side of the Y-shaped connecting rod 19 is fixedly installed on the adjusting wheel 18 and is axially symmetrically distributed on the adjusting wheel 18. A set of axially symmetrically distributed clamping rods 20 are rotatably installed on the side of the mounting block 16. The top of the clamping rod 20 is rotatably connected to the connecting rod 19, and the bottom of the clamping rod 20 is fixedly connected to a clamping block. The clamping block at the bottom of the clamping rod 20 is on the outside of the top of the pressure plate 11. The connecting rod 19 of the clamping structure is made of high-strength alloy material, which has good toughness and fatigue resistance. It can maintain structural stability during long-term repeated movement and avoid uneven clamping force due to deformation. The clamping block at the bottom of the clamping rod 20 is wrapped with elastic material, which can enhance the friction with the top of the pressure plate 11 to ensure firm clamping, and reduce the rigid impact on the pressure plate 11 through elastic buffering, protecting the surface of the pressure plate 11 from damage.

[0059] Working principle: First, the mounting block 16 in the fixed structure is fixed in the mounting groove 15 of the top plate 14 by the fixing pin 21, providing a stable foundation for the overall operation. When the wax mold is formed, the adjusting wheel 18 of the adjusting structure is rotated. Since the connecting rod 19 is Y-shaped and one side is fixed on the adjusting wheel 18 and is axially symmetrically distributed, the rotation of the adjusting wheel 18 will drive the connecting rod 19 to move, thereby pulling the clamping rod 20 of the clamping structure, so that the clamping block at the bottom of the clamping rod 20 tightens inward, clamping the bend at the top of the pressure plate 11, so that the mold 13 of the mold structure and the model groove on the side of the mold cavity 12 are precisely matched to form a closed cavity. Then, the wax injection structure starts to work. The molten wax enters through the through round hole on the side of the wax injection port 6 and is transported to the cavity formed by the mold 13 and the mold cavity 12 through the wax injection mounting column 5. The round hole design of the wax injection port 6 ensures that the wax is injected evenly and avoids excessive local pressure that could cause mold deformation. After the wax cools and solidifies, the adjusting wheel 18 is rotated in the opposite direction. The throttle wheel 18 and connecting rod 19 drive the clamping rod 20 to open outward, releasing the clamping of the pressure plate 11. At this time, the turntable 9 of the sliding structure is rotated, and the sliding rod 10 at the top of the turntable 9 will drive the pressure plate 11 to slide along the direction of the sliding rod 10. Since the mold 13 and the mold cavity 12 are respectively fixed inside the pressure plates 11 on both sides, the two are smoothly separated with the sliding of the pressure plate 11, realizing the flexible demolding of the wax mold. In this process, the support plate 7 of the mounting structure is fixed to the fixing plate 1 2 and the fixing plate 2 3 by screws, providing stable support for the sliding structure and mold assembly. The rotational connection between the L-shaped top plate 14 and the fixing plate 2 3 makes it easy to quickly open the mold and take out the wax mold after demolding. This linkage method not only avoids the damage to the wax mold caused by traditional manual prying, but also improves the demolding efficiency through mechanized adjustment and sliding structure. At the same time, it reduces the direct friction between the mold 13 and the mold cavity 12, effectively extending the service life of the mold and ensuring the dimensional accuracy and molding quality of the wax mold in long-term production.
