Description

Technical Field

[0001] The utility model relates to the technical field of wax mold casting, in particular to a wax mold casting device capable of rapid cooling. Background Technique

[0002] The wax mold is a core component in the investment casting (lost wax casting) process. It is a precision model used to make metal castings. The wax mold is usually made of low-melting-point wax material, with high precision and good surface finish, and can precisely replicate the shape and details required for the casting.

[0003] At present, the existing wax mold casting devices capable of rapid cooling usually first install the molds to be used, and then inject the wax material heated to the molten state into the molds. Under the action of the condenser, the wax molds in the molds are rapidly cooled. After the wax molds are cooled and solidified, they are taken out of the molds. However, the existing devices are prone to cause uneven local cooling, resulting in thermal stress caused by temperature difference, leading to deformation or cracking of the wax molds during the cooling process, and the cost of using the condenser is relatively high.

[0004] Therefore, in view of the above problems, a wax mold casting device capable of rapid cooling that can improve the cooling uniformity, reduce the risk of deformation or cracking of the wax molds during the cooling process, and reduce the cost has now been developed. Content of the Utility Model

[0005] In order to overcome the shortcomings that the existing devices are prone to cause uneven local cooling, resulting in deformation or cracking of the wax molds during the cooling process, and the high cost, the utility model provides a wax mold casting device capable of rapid cooling that can improve the cooling uniformity, reduce the risk of deformation or cracking of the wax molds during the cooling process, and reduce the cost.

[0006] The technical solution of the utility model is: a wax mold casting device capable of rapid cooling, including a water storage tank, a rotating frame, an electric telescopic rod, a bolt, a mold, a wax injector, a wax injection head, and a motor. The left side of the upper part of the water storage tank is connected with a wax injector, and the wax injector is connected with a wax injection head. The right side of the upper part of the water storage tank is connected with a motor, and the output shaft of the motor is connected with a rotating frame. A plurality of electric telescopic rods are connected to the rotating frame. The telescopic ends of the electric telescopic rods are clamped with a mold, and bolts are clamped between the telescopic ends of the electric telescopic rods and the mold to fix the mold through the bolts. The lower half of the mold is immersed in the water in the water storage tank. The wax material is injected into the mold through the wax injection head to cast the inside of the mold. After the casting is completed, the rotating frame is driven to rotate by the rotation of the output shaft of the motor. The rotation of the rotating frame drives the mold to rotate through the electric telescopic rod. During the rotation process, the mold is evenly contacted with the water for cooling. After the cooling is completed, the mold is driven to separate by the telescopic end of the electric telescopic rod. The wax mold inside the mold contacts the water, and the wax mold is demolded into the water, using the water as the demolding medium to reduce the adhesion between the wax mold and the mold.

[0007] In one of the embodiments, a supporting wheel frame is further included. The supporting wheel frame is symmetrically connected to the inner wall of the water reservoir. The supporting wheel frame is in contact with the rotating frame. The rotating frame is supported by the supporting wheel frame to improve the stability of the supporting wheel frame when rotating.

[0008] In one of the embodiments, a limiting frame is further included, and the limiting frame is connected between the electric telescopic rod and the rotating frame, and the stability of the electric telescopic rod is ensured by the limiting frame.

[0009] In one of the embodiments, a water pump is also included. The water pump is connected to the right side of the lower part of the water reservoir. The water in the water reservoir is replaced by the water pump to keep the water in the water reservoir at a low temperature.

[0010] In one of the embodiments, a buffer cloth is further included. The buffer cloth is connected to the inside of the water reservoir. When the wax model is separated from the mold, the buffer cloth is used to support and buffer the wax model to prevent it from falling into the water and colliding with the bottom of the water reservoir and causing damage.

[0011] In one of the embodiments, an air pump and a bubble generator are also included. The lower part of the water reservoir is connected to the air pump, and the air pump is connected to the bubble generator. The bubble generator is located in the lower part of the water reservoir. A large number of bubbles are generated through the bubble generator under the action of the air pump. The generation of bubbles during demolding reduces the contact pressure between the wax model and the mold, forming a layer of air cushion, making it easier to remove the wax model from the mold, reducing the difficulty of demolding and possible damage.

[0012] The beneficial effects are as follows: 1. The utility model drives the rotating frame to rotate through the rotation of the motor output shaft, and the rotation of the rotating frame drives the mold to rotate through the electric telescopic rod. During the rotation process, the mold is evenly contacted with water for cooling, which can improve the cooling uniformity, reduce the risk of deformation or cracking of the wax mold during cooling, and reduce costs.

[0013] 2. The utility model uses a buffer cloth to support and buffer the wax model, and generates a large number of bubbles through a bubble generator under the action of an air pump, thereby reducing the contact pressure between the wax model and the mold, forming a layer of air cushion, which can reduce the difficulty of demolding and possible damage.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

The left side of the upper part of the water storage tank 1 is connected to the wax injection machine 5, the wax injection machine 5 is connected to the wax injection head 51, the right side of the upper part of the water storage tank 1 is connected to the motor 6, the output shaft of the motor 6 is connected to the rotating frame 3, four electric telescopic rods 31 are connected to the rotating frame 3, the mold 4 is clamped between the telescopic ends of the electric telescopic rods 31, and pins 33 are clamped between the telescopic ends of the electric telescopic rods 31 and the mold 4 respectively to fix the mold 4 through the pins 33. The lower half of the mold 4 is immersed in the water in the water storage tank 1. The wax material is injected into the mold 4 through the wax injection head 51 to cast the inside of the mold 4. After the casting is completed, the rotating frame 3 is driven to rotate by the rotation of the output shaft of the motor 6. The rotation of the rotating frame 3 drives the mold 4 to rotate through the electric telescopic rod 31. During the rotation process, the mold 4 is evenly contacted with water for cooling. After the cooling is completed, the mold 4 is driven to separate by the telescopic end of the electric telescopic rod 31. The wax mold inside the mold 4 contacts with water, and the wax mold is demolded into the water, making water as the demolding medium to reduce the adhesion between the wax mold and the mold 4;

[0024] It also includes a support wheel frame 2, and the inner wall of the water reservoir 1 is symmetrically connected to the support wheel frame 2, and the support wheel frame 2 is in contact with the rotating frame 3. The rotating frame 3 is supported by the support wheel frame 2 to improve the stability of the support wheel frame 2 when rotating;

[0025] It also includes a limiting frame 32, and the electric telescopic rod 31 is connected to the rotating frame 3 by the limiting frame 32, and the stability of the electric telescopic rod 31 is ensured by the limiting frame 32;

[0026] It also includes a water pump 7, which is connected to the right side of the lower part of the water reservoir 1. The water in the water reservoir 1 is replaced by the water pump 7 to keep the water in the water reservoir 1 at a low temperature;

[0027] It also includes a buffer cloth 8, which is connected to the inside of the water reservoir 1. When the wax model is separated from the mold 4, the buffer cloth 8 is used to receive and buffer the wax model to prevent it from falling into the water and colliding with the bottom of the water reservoir 1 and causing damage;

[0028] It also includes an air pump 9 and a bubble generator 10. The air pump 9 is connected to the lower part of the water reservoir 1, and the bubble generator 10 is connected to the air pump 9. The bubble generator 10 is located in the lower part of the water reservoir 1. Under the action of the air pump 9, a large number of bubbles are generated through the bubble generator 10. The generation of bubbles during demolding reduces the contact pressure between the wax model and the mold 4, forming a layer of air cushion, making it easier for the wax model to be removed from the mold 4, reducing the difficulty of demolding and possible damage.

[0029] When the utility model is in use, first, the utility model needs to be installed in the operation area. Then, a suitable mold 4 is selected for installation and fixed by a bolt 33. The lower half of the mold 4 is immersed in the water in the reservoir 1. After the installation is completed, the wax material is injected into the mold 4 through the wax injection head 51 to cast the inside of the mold 4. After the casting is completed, the output shaft of the motor 6 rotates to drive the rotary frame 3 to rotate. The rotation of the rotary frame 3 drives the mold 4 to rotate through the electric telescopic rod 31. During the rotation process, the mold 4 is evenly contacted with the water for cooling. The rotary frame 3 is supported by the support wheel frame 2 to improve the stability during the rotation of the support wheel frame 2. After the cooling is completed, the mold 4 is separated by the telescopic end of the electric telescopic rod 31. The wax mold inside the mold 4 contacts the water, and the wax mold is demolded into the water, using water as the demolding medium to reduce the adhesion between the wax mold and the mold 4. When the wax mold is separated from the mold 4, the wax mold is received and buffered by the buffer cloth 8 to prevent damage to the wax mold caused by hitting the bottom of the reservoir 1 after falling into the water. Under the action of the air pump 9, a large number of bubbles are generated by the bubble generator 10. The generation of bubbles during demolding can reduce the contact pressure between the wax mold and the mold 4, forming an air cushion, making it easier for the wax mold to be removed from the mold 4, reducing the difficulty of demolding and possible damage. Then, the wax mold can be taken out of the water. Then, the water in the reservoir 1 is often replaced by the water pump 7 to keep the water in the reservoir 1 in a low-temperature state. When the mold 4 needs to be replaced, first, the bolt 33 is disengaged from the mold 4 and the telescopic end of the electric telescopic rod 31. Then, the mold 4 is disengaged from the telescopic end of the electric telescopic rod 31. Next, the required mold 4 is clamped to the telescopic end of the electric telescopic rod 31. Then, the bolt 33 is clamped to the mold 4 and the telescopic end of the electric telescopic rod 31 to fix the mold 4.
