Description

Technical Field

[0001] This utility model belongs to the field of metal parts manufacturing technology, and in particular relates to a rapid cooling device for a wax casting machine. Background Technology

[0002] When producing high-precision metal parts, due to the complex structure of the metal parts, investment casting is used. This involves making a wax model, then placing a refractory plaster mold on the surface of the wax model, melting and removing the wax model, solidifying the refractory plaster mold, and then pouring the molten metal into it for cooling, thereby obtaining the high-precision metal part.

[0003] When cooling plaster molds in batches, air cooling or water cooling is often used. However, since traditional air cooling or water cooling methods usually cool from one end to the other, the temperature at the inlet is lower, while the temperature closer to the outlet is the same as the mold temperature. This results in the mold temperature near the inlet cooling faster and the mold temperature closer to the outlet cooling slower, leading to different cooling rates for each mold core and poor cooling effect.

[0004] Therefore, how to provide a rapid cooling device for a wax casting machine is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a rapid cooling device for a wax casting machine, which aims to solve the problems mentioned in the background art.

[0006] This utility model is implemented as follows: a rapid cooling device for a wax casting machine, comprising;

[0007] Cooling frame;

The inner end of the multi-stage bent cooling pipe is fixedly connected to the bottom of the second drain pipe. Air-cooling units are symmetrically arranged on the front and rear sides of the cooling frame to provide auxiliary cooling for the multi-stage bent cooling pipe.

[0015] Preferably, the water storage structure includes a water storage frame and a sealing plate. The water storage frame is located at the top of the outer side of the mold placement groove, and adjacent water storage frames are fixedly connected. The sealing plate is movably inserted into the bottom of the inner side of the water storage frame, and a spring is fixedly installed on its top, which is fixedly connected to the top of the water storage frame. The water storage frames on both sides are fixedly connected to the pumping structure.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of a rapid cooling device for a wax casting machine according to an embodiment of the present invention, comprising:

[0032] Cooling frame 1;

[0033] Mold placement slot 2, the mold placement slot 2 array is set at the upper end of cooling frame 1;

[0034] Water storage base plate 13 is set at the bottom edge of the mold placement groove 2;

[0035] Water storage tank 6 is located at the lower end of cooling frame 1;

[0036] A water storage structure, the water storage structure array is set at the top of the outer side of the mold placement groove 2;

[0037] The pumping structure is located on both sides of the water storage tank 6 and is fixedly connected to both sides of the water storage structure.

[0038] In this embodiment of the invention, when in use, water is injected into the interconnected water storage structures at the top of the outer side of the mold placement slot 2 through the water pumping structure. When all the water storage structures are full of water, when water is injected again, the water pressure of the water storage structures will increase and open synchronously, thereby simultaneously cooling all the mold placement slots 2 with water, so that all the mold placement slots 2 cool at the same rate, thus facilitating synchronous removal.

[0039] like Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, a water storage tank 14 is arrayed on the top of the water storage base plate 13, a lifting plate 4 is provided in the middle of the cooling frame 1, and a cooling structure is provided between the water storage tank 14 and the water storage tank 6.

[0040] The cooling structure includes a second drain pipe 15 and a water injection pipe 17. The second drain pipe 15 is arrayed and inserted into the bottom of the water storage tank 14, and its bottom penetrates the surface of the lifting plate 4. The water injection pipe 17 is symmetrically installed on the top of both sides of the water storage tank 6, and the top is symmetrically connected to a multi-stage bent cooling pipe 16. The inner end of the multi-stage bent cooling pipe 16 is fixedly connected to the bottom of the second drain pipe 15. Air-cooling units are symmetrically arranged on the front and rear sides of the cooling frame 1 to provide auxiliary cooling for the multi-stage bent cooling pipe 16.

[0041] In this embodiment of the utility model, when in use, the water cooling the mold placement groove 2 flows to the water storage base plate 13, and then along the water storage groove 14 at the bottom of the water storage base plate 13, and then into the second drain pipe 15, thereby entering the multi-stage bent cooling pipe 16. Then, with the cooperation of the ventilation groove 18 and the fan 19, the water in the multi-stage bent cooling pipe 16 is rapidly cooled, and then discharged back into the water storage tank 6 through the water injection pipe 17.

[0042] By setting up a cooling structure, the water used for cooling the mold placement tank 2 can be cooled down quickly, thereby realizing the recycling of water resources.

[0043] like Figure 2, Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the water storage structure includes a water storage frame 10 and a sealing plate 12. The water storage frame 10 is disposed at the top of the outer side of the mold placement groove 2, and adjacent water storage frames 10 are fixedly connected. The sealing plate 12 is movably inserted into the bottom of the inner side of the water storage frame 10, and a spring 11 is fixedly installed on the top and fixedly connected to the top of the water storage frame 10. The water storage frames 10 on both sides are fixedly connected to the pumping structure.

[0044] In this embodiment of the utility model, when in use, water is discharged into the water storage frame 10, which then fills the water storage frame 10, which is connected to each other and distributed at the top of the mold placement groove 2, with water. When water is injected, the pressure of the water storage frame 10 increases, which causes the sealing plate 12 to overcome the elasticity of the spring 11, and then causes the water storage frame 10 distributed at the top of the mold placement groove 2 to open synchronously.

[0045] By setting up a water storage structure, water flows synchronously to the surface of all mold placement slots 2 and flows from top to bottom to cool the mold placement slots 2. This allows all mold placement slots 2 to be cooled rapidly and synchronously, so that the molds in the mold placement slots 2 can be removed synchronously.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the water pumping structure includes a water pumping pipe 7 and a first drain pipe 9. The water pumping pipe 7 is fixedly installed on the left side of the water storage tank 6, and a water distribution pipe 8 is fixedly installed on the top. The first drain pipe 9 is inserted into the top of the water distribution pipe 8 in an array, and penetrates the surface of the cooling frame 1 and is movably inserted into both sides of the water storage structure.

[0047] In this embodiment of the utility model, when in use, the water pump of the water pumping pipe 7 is started to pump the water in the water storage tank 6 into the water distribution pipe 8, and then into the first drain pipe 9 to discharge the water in the water storage tank 6 into the water storage frame 10, thereby filling the water storage structure that is distributed all over the top of the mold placement groove 2 and interconnected with each other with water.

[0048] By setting up a pumping structure, all the first drain pipes 9 are filled with water simultaneously, and the water storage structure expands and leaks water synchronously.

[0049] like Figure 2 As shown, in a preferred embodiment of the present invention, lifting screws 3 are symmetrically arranged on both sides of the cooling frame 1 and are movably connected to both sides of the lifting plate 4. Top rods 5 are arrayed on the top of the lifting plate 4 and are movably inserted into the mold placement groove 2.

[0050] In this embodiment of the utility model, when in use, the motor at the bottom of the lifting screw 3 is started, which causes the lifting screw 3 to rotate, thereby controlling the lifting plate 4 to rise and fall, and driving the top rod 5 to rise and fall, pushing the mold in the mold placement slot 2 out, thus facilitating the removal of the mold.

[0051] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the air-cooled unit includes a ventilation slot 18, which is symmetrically opened on the front and rear sides of the lower end of the cooling frame 1, and a fan 19 is fixedly installed in the middle of the ventilation slot 18.

[0052] In this embodiment of the utility model, when in use, the fan 19 is started, and then the outside air is drawn into the cooling frame 1 to cool the multi-stage bent cooling pipe 16, and then blown out from the ventilation slot 18 on the other side.

[0053] By setting up an air-cooling unit, the cooling speed of the multi-stage bent cooling pipe 16 is accelerated, which in turn facilitates the recycling of water.

[0054] like Figure 2 As shown, in a preferred embodiment of this utility model, the number of ejector pins 5 corresponds to the number of mold placement slots 2, and the diameter of the ejector pin 5 is equal to the inner diameter of the mold placement slot 2.

[0055] In this embodiment of the utility model, when in use, the number of ejector pins 5 is set to correspond to the number of mold placement slots 2, and the diameter of the ejector pins 5 is equal to the inner diameter of the mold placement slots 2, thereby facilitating the ejection of the mold from the mold placement slots 2.

[0056] The present invention provides a rapid cooling device for a wax casting machine in the above embodiments. When in use, the mold is placed in the mold placement groove 2 and wax liquid is injected in sequence.

[0057] Then, the water pumping pipe 7 is activated to pump the water in the water storage tank 6 into the water distribution pipe 8, and then into the first drain pipe 9 to discharge the water in the water storage tank 6 into the water storage frame 10. This fills the water storage frame 10, which is connected to each other and covers the top of the mold placement slot 2. As water is injected, the pressure in the water storage frame 10 increases, which causes the sealing plate 12 to overcome the elasticity of the spring 11. This causes the water storage frames 10 covering the top of the mold placement slot 2 to open simultaneously, allowing water to flow to the surface of the mold placement slot 2 and flow from top to bottom to cool the mold placement slot 2. This allows all the mold placement slots 2 to be cooled rapidly and simultaneously, so that the molds in the mold placement slots 2 can be removed simultaneously.

[0058] The water then flows onto the water storage base plate 13, and then along the water storage tank 14 at the bottom of the water storage base plate 13, into the second drain pipe 15, and then into the multi-stage bending cooling pipe 16. With the cooperation of the ventilation slot 18 and the fan 19, the water in the multi-stage bending cooling pipe 16 is quickly cooled, and then discharged back into the water storage tank 6 through the water injection pipe 17, thus realizing the circulation of water resources.

[0059] Then, the lifting screws 3 on both sides of the cooling frame 1 are activated, which causes the lifting plate 4 to rise and simultaneously drive the ejector rod 5 to rise, so that the mold placed in the slot 2 can be ejected at the same time.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
