Description

Technical Field

[0001] This utility model relates to the field of wax pattern casting technology, specifically to a casting wax pattern cooling pool with uniform cooling. Background Technology

[0002] In the precision casting production process, there is an important question: where to place the wax pattern after it is removed from the mold? Currently, more than half of the industry places the wax pattern in water after it is removed. Whether it is medium-temperature wax or low-temperature wax, placing it in water is the first choice. The reason is simple: the wax pattern cools down quickly and is not easy to stick or break. Therefore, most wax patterns are now cooled down by cooling pools.

[0003] The existing wax model cooling tank has an extremely simple structure; it's simply a pool filled with water. After the wax model is formed, it's placed directly into the tank to exchange heat with the cooling water and cool down. Since the wax model's density is less than water, it floats, ensuring even support for all parts of the model and preventing deformation due to gravity. Furthermore, the cooling water in the existing wax model cooling tank doesn't require special cooling, avoiding excessive shrinkage and deformation caused by excessively low water temperatures, making it very convenient to use.

[0004] However, there is also a problem with cooling pools for cooling wax models: the water circulation and heat convection are relatively weak, and there is a temperature difference between the top and bottom of the water. This can easily cause uneven cooling of the wax model, leading to deformation. Existing cooling pools simply use water pipes connected to circulation pumps for circulation. Due to the small inlet and outlet area of ​​the water pipes, it is difficult to ensure that the water circulation rate is similar in all parts of the large-volume cooling pool, thus making it difficult to cool the model evenly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a uniformly cooled casting wax mold cooling pool, which solves the problem that the large differences in water circulation rates at different locations within the existing wax mold cooling pool make it difficult to uniformly cool the wax mold.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A uniformly cooled casting wax mold cooling pool includes a U-shaped cooling pool placed in front of the wax injection station. A permeable canvas is arranged along the inner wall of the U-shaped cooling pool. The upper and lower edges of the permeable canvas are fixed to the inner wall of the U-shaped cooling pool. A gauze mesh is arranged on the inner side of the area surrounded by the permeable canvas. The edge of the gauze mesh is fixed to the permeable canvas.

[0008] The U-shaped cooling pool has water inlet pipes on both sides of its back side. The water inlet pipes pass through the U-shaped cooling pool and are connected to the diversion pipe between the inside of the U-shaped cooling pool and the permeable canvas. The bottom of the U-shaped cooling pool is connected to the front side with a water outlet pipe. A circulation pump is connected between the water outlet pipe and the water inlet pipe.

[0009] Preferably, pressure strips are provided on the outer sides of both the upper and lower edges of the permeable canvas, and the pressure strips clamp the permeable canvas and fix it to the inner wall of the U-shaped cooling pool with screws.

[0010] Preferably, the permeable canvas is positioned in the middle and near the top of the U-shaped cooling pool, and the gauze mesh corresponds to the upper half of the permeable canvas.

[0011] Preferably, the diversion pipe includes multiple horizontal pipes equidistantly arranged in a vertical direction, and the middle parts of the multiple horizontal pipes are connected by a vertical connecting pipe, and the water inlet pipe is connected to the center of the diversion pipe.

[0012] Preferably, the outlet pipe is located on the vertical surface of the U-shaped cooling pool, and the circulating pump is connected to the inlet pipes symmetrically arranged on both sides through a tee pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model sets up a permeable canvas and a gauze mesh in the U-shaped cooling pool. Wax molds are placed in the gauze mesh, which avoids the wax molds from gathering and helps to prevent the wax molds from colliding with each other. Water flows out from the water inlet pipe and the branch pipe, flows along the area between the permeable canvas and the U-shaped cooling pool, and seeps out from the permeable canvas to the center of the U-shaped cooling pool. Water is discharged from the center of the bottom of the U-shaped cooling pool near the front, which avoids local water ingress. This makes the water circulation rate in the U-shaped cooling pool more uniform, which is conducive to the uniform cooling of the wax molds that are placed evenly. It avoids large abnormal deformation caused by temperature difference and solves the problem that the water circulation rate in the existing wax mold cooling pool is large and it is difficult to cool the wax molds evenly.

[0015] (2) Existing wax model cooling pools are rectangular water tanks placed on one side of the workstation. Due to the limitation of arm length, the staff can only place the wax model in the cooling pool near the workstation when standing at the workstation. The wax model tends to gather together, which is not conducive to uniform cooling. This utility model is designed with a U-shaped cooling pool according to the workstation and the staff's position. It is convenient to place the wax model taken out by wax injection into the cooling pool to the left, right and back. The operation is more convenient. Moreover, the angle and frequency of the staff turning left and right when placing the wax model are relatively close, which is more friendly to the health of the staff. Attached Figure Description

[0021] 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.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a uniformly cooled casting wax mold cooling pool, including a U-shaped cooling pool 2 placed in front of the wax injection station 1. A permeable canvas 3 is arranged along the inner wall of the U-shaped cooling pool 2. The upper and lower edges of the permeable canvas 3 are fixed to the inner wall of the U-shaped cooling pool 2. Pressure strips 9 are arranged on the outer sides of the upper and lower edges of the permeable canvas 3. The pressure strips 9 clamp the permeable canvas 3 and fix it to the inner wall of the U-shaped cooling pool 2 with screws.

[0023] The permeable canvas 3 is set in the middle and near the top of the U-shaped cooling pool 2. A gauze mesh 4 is set on the inner side of the area surrounding the permeable canvas 3. The edge of the gauze mesh 4 is fixed on the permeable canvas 3. The gauze mesh 4 corresponds to the upper part of the permeable canvas 3.

[0024] Water inlet pipes 5 are provided on both sides of the back of the U-shaped cooling pool 2. The water inlet pipes 5 pass through the U-shaped cooling pool 2 and are connected to the diversion pipe 6 between the interior of the U-shaped cooling pool 2 and the permeable canvas 3. The diversion pipe 6 includes multiple horizontal pipes 601 arranged at equal intervals in the vertical direction. The middle of the multiple horizontal pipes 601 are connected by a vertical connecting pipe 602. The water inlet pipe 5 is connected to the center of the diversion pipe 6.

[0025] The bottom of the U-shaped cooling pool 2 is connected to a water outlet pipe 7 near the front. The water outlet pipe 7 is located on the vertical surface of the U-shaped cooling pool 2. A circulation pump 8 is connected between the water outlet pipe 7 and the water inlet pipe 5. The circulation pump 8 is connected to the water inlet pipes 5 symmetrically arranged on both sides through a three-way pipe 10.

[0026] Working principle:

[0027] Based on the workstation and staff positioning design, a U-shaped cooling pool 2 is set up to facilitate the placement of wax molds removed from the wax injection process into the gauze mesh 4 in the cooling pool, which is convenient for operation and avoids wax mold aggregation and collision. Water flows out from the inlet pipe 5 and the branch pipe 6, flowing along the area between the permeable canvas 3 and the U-shaped cooling pool 2. At the same time, it seeps out from the permeable canvas 3 into the center of the U-shaped cooling pool 2 and exits at the bottom center near the front of the U-shaped cooling pool 2, avoiding local water ingress. This makes the water circulation rate in the U-shaped cooling pool 2 more uniform, which is conducive to the uniform cooling of the wax molds.
