A water-cooled mold for a gear support

Abstract

This application relates to a water-cooled mold for a gear bracket, specifically within the technical field of gear bracket die-casting molds. The mold includes an upper mold and a lower mold. An upper mold base is fixedly mounted on the upper surface of the upper mold, and a lower mold base is fixedly mounted on the bottom surface of the lower mold. Water tanks are located on both the left and right sides of the upper mold. This application utilizes components such as a first water pump, a first water pipe, a second water pump, and a second water pipe. After the upper and lower molds are closed for die casting, the first and second water pumps are activated. Cooling water is drawn from the corresponding water tanks via the first and second water pumps and their respective pipes, and then transferred through the first water pipe, hose, and second water pipe. This allows the cooling water to remove heat from the upper mold, lower mold, upper mold base, and lower mold base. The heat-carrying cooling water is then discharged through the first and second drain pipes, thereby shortening the cooling time of the die-cast parts, accelerating the solidification of the die-cast parts, and improving production efficiency.

Description

Technical Field

[0001] This application relates to the field of gear bracket die casting mold technology, and in particular to a water-cooled mold for a gear bracket. Background Technology

[0002] Gear bracket molds are high-precision forming tools designed and manufactured specifically for gear bracket parts. They are typically made of metal materials through machining, heat treatment, and precision grinding. The mold uses processes such as die casting to inject molten metal into a closed cavity, where it is cooled and solidified under high pressure to form a gear bracket structure that meets the design requirements. It is widely used in automotive transmission systems, industrial speed reducers, power tools, and other fields. Its design must comprehensively consider material flowability, mold strength, and product operating conditions, making it a key piece of equipment for ensuring the quality and cost of mass production of gear brackets.

[0003] However, in the existing technology, it has been found that when die-casting gear supports, the temperature of the upper mold, upper mold base, lower mold and lower mold base gradually increases because molten material needs to be fed into the mold cavities of the upper and lower molds for forming. This results in a long cooling time and a long solidification time for the gear support, which in turn leads to low production efficiency. Summary of the Invention

[0004] Technical problems to be solved

[0005] The purpose of this application is to provide a water-cooled mold for a gear bracket, which has the advantages of shortening the cooling time of the die-casting, accelerating the solidification of the die-casting, and improving production efficiency. It solves the problem in the prior art that during die casting, the temperature of the molten material causes the temperature of the upper mold, upper mold base, lower mold and lower mold base to gradually rise, resulting in a long cooling time and long solidification waiting time for the gear bracket, which in turn leads to low production efficiency.

[0006] The water-cooled mold for a gear bracket provided in this application adopts the following technical solution: it includes an upper mold and a lower mold. An upper mold base is fixedly installed on the upper surface of the upper mold, and a lower mold base is fixedly installed on the bottom surface of the lower mold. Water tanks are provided on the left and right sides of the upper mold. A first water pump is fixedly installed in one of the water tanks through a pipe. The bottom surface of the first water pump is fixedly connected to the upper surface of the corresponding water tank. A first water pipe is fixedly installed at the output end of the first water pump. The other end of the first water pipe is fixedly connected to a first drain pipe. A second water pump is fixedly installed in the other water tank through a pipe. The bottom surface of the second water pump is fixedly connected to the upper surface of the corresponding water tank. A flexible hose is fixedly installed at the output end of the second water pump. A second water pipe is fixedly connected to the top end of the flexible hose. The other end of the second water pipe is fixedly connected to a second drain pipe. The outer surface of the first water pipe is fixedly connected to the interior of the lower mold and the lower mold base, and the outer surface of the second water pipe is fixedly connected to the interior of the upper mold and the upper mold base.

[0007] By adopting the above technical solution, an upper mold base is installed on the upper surface of the upper mold. When the upper mold base moves, the upper mold can move accordingly. A lower mold base is installed on the bottom surface of the lower mold to support the lower mold. The upper and lower molds can close together. A water tank is provided on the left and right sides of the upper mold. A first water pump and a second water pump can respectively draw cooling water from the corresponding water tank. A first water pipe runs through the lower mold and the lower mold base, allowing the cooling water to be transferred through the first water pump and the first water pipe, thus carrying away the heat from the lower mold and the lower mold base. Finally, the heat is transferred out through the first drain pipe. A second water pipe runs through the inside of the upper mold and upper mold base, and the second water pipe is connected to a hose. The hose is then connected to a second water pump, allowing the second water pump, hose, and second water pipe to transfer the cooling water. This removes heat from the upper mold and upper mold base, and the heat is then transferred out through the second drain pipe. This allows the heat generated by the upper mold, lower mold, upper mold base, and lower mold base during die casting to be quickly removed, thereby shortening the cooling time of the die casting, accelerating the solidification of the die casting, and improving production efficiency.

[0008] Preferably, a mounting base is fixedly connected to the bottom surface of the lower mold base, and the left and right sides of the mounting base are fixedly connected to the corresponding water tank side that is close to each other.

[0009] By adopting the above technical solution, an installation seat is set on the bottom surface of the lower mold base. The installation seat can be used to install the lower mold base and the lower mold at a designated position, thereby supporting the lower mold and the lower mold base. The left side of the installation seat is connected to the corresponding water tank, so that the water tank can be installed on the left and right sides of the installation seat.

[0010] Preferably, the upper surface of the mounting base is fixedly connected with guide posts arranged at equal intervals, and each guide post has a sliding sleeve slidably connected to its outer surface.

[0011] By adopting the above technical solution, a guide post is set on the upper surface of the mounting base to support the guide post. A sliding sleeve is set on the surface of the guide post, and the guide post and the sliding sleeve are set as a sliding connection to limit the movement of the sliding sleeve.

[0012] Preferably, the outer surface of each of the sliding sleeves is fixedly connected to the inner wall of the upper mold base.

[0013] By adopting the above technical solution, the sliding sleeve is fixed to the inner wall of the upper mold base, so that the upper mold base can move up and down on the surface of the guide column through the sliding sleeve, thereby ensuring the stability of the upper mold base when it moves up and down.

[0014] Preferably, a top plate is provided above the upper mold base, and the top of each guide post is fixedly connected to the bottom surface of the top plate.

[0015] By adopting the above technical solution, a top plate is set above the upper mold base, and the bottom surface of the top plate is fixed to the top of the corresponding guide column to achieve support for the top plate.

[0016] Preferably, a die-casting pipe is fixedly installed on the inner wall of the upper mold, and a feed pipe is fixedly connected to the upper surface of the die-casting pipe.

[0017] By adopting the above technical solution, the die-casting pipe fitting is installed on the inner wall of the upper mold and fixed. A feed pipe is connected to the upper surface of the die-casting pipe fitting, so that the die-casting material inside the feed pipe is input into the interior of the die-casting pipe fitting.

[0018] Preferably, a tapered component is fixedly installed on the inner wall of the lower mold, and a guide groove is formed on the outer surface of the tapered component.

[0019] By adopting the above technical solution, a conical part is installed on the inner wall of the lower mold. When the upper mold and the lower mold are closed, the die-casting pipe and the conical part can be matched. A guide groove is opened on the surface of the conical part. Through the conical shape of the conical part and the guide groove on the surface, the die-casting material can enter between the upper mold and the lower mold and flow through the channel between the upper mold and the lower mold.

[0020] Preferably, each of the water tanks has a sealing cap on its upper surface.

[0021] By adopting the above technical solution, a sealing cover is set on the upper surface of the water tank, and the sealing cover can be opened to facilitate the replenishment of cooling water into the water tank.

[0022] Beneficial effects

[0023] This water-cooled mold for a gear bracket, by setting up components such as a first water pump, a first water pipe, a second water pump, and a second water pipe, allows the first and second water pumps to be activated after the upper and lower molds are closed for die casting. Cooling water is drawn from the corresponding water tanks through the first and second water pumps and pipes, and then transferred through the first water pipe, the flexible hose, and the second water pipe. This allows the cooling water to carry away the heat from the upper and lower molds, the upper mold base, and the lower mold base. The cooling water carrying the heat is then discharged through the first and second drain pipes, thereby shortening the cooling time of the die casting, accelerating the solidification of the die casting, and improving production efficiency.

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0033] Example 1: A water-cooled mold for a gear support, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 6 The system includes an upper mold 1 and a lower mold 2. An upper mold base 3 is fixedly installed on the upper surface of the upper mold 1, and a lower mold base 4 is fixedly installed on the bottom surface of the lower mold 2. By installing the upper mold base 3 on the upper surface of the upper mold 1, the upper mold 1 can move along with the upper mold base 3. The lower mold base 4 is installed on the bottom surface of the lower mold 2 to support the lower mold 2. The upper mold 1 and the lower mold 2 can be closed. Water tanks 5 are provided on the left and right sides of the upper mold 1. One of the water tanks 5 is fixedly installed with a first water pump 6 through a pipe.

The first water pump 6 and the second water pump 9 can respectively draw the cooling water inside the corresponding water tank 5. The first water pipe 7 passes through the lower mold 2 and the lower mold base 4, so that the cooling water can be transferred through the first water pump 6 and the first water pipe 7, and the heat of the lower mold 2 and the lower mold base 4 is carried away. Finally, it is transferred out through the first drain pipe 8.

[0034] Please see Figure 1 , Figure 2 and Figure 6Another water tank 5 is fixedly equipped with a second water pump 9 via a pipe. The bottom surface of the second water pump 9 is fixedly connected to the upper surface of the corresponding water tank 5.

The second water pipe 11 runs through the part and connects the second water pipe 11 to the hose 10. The hose 10 is then connected to the second water pump 9, so that the second water pump 9, hose 10, and second water pipe 11 can transfer cooling water, thereby removing the heat from the upper mold 1 and upper mold base 3. Finally, the heat is transferred out through the second drain pipe 12, so that the heat generated by the upper mold 1, lower mold 2, upper mold base 3, and lower mold base 4 during die casting can be quickly removed, thereby shortening the cooling time of the die casting, accelerating the solidification of the die casting, and improving production efficiency.

[0035] Example 2: A water-cooled mold for a gear support, please refer to... Figure 2 , Figure 3 and Figure 4 A mounting base 14 is fixedly connected to the bottom surface of the lower mold base 4. The left and right sides of the mounting base 14 are fixedly connected to the sides of the corresponding water tanks 5 that are close to each other. The mounting base 14 is provided on the bottom surface of the lower mold base 4. The lower mold base 4 and the lower mold 2 can be installed in a designated position through the mounting base 14, thereby achieving support for the lower mold 2 and the lower mold base 4. The left side of the mounting base 14 is connected to the corresponding water tank 5, so that the water tank 5 can be installed on the left and right sides of the mounting base 14. The upper surface of the mounting base 14 is fixedly connected to guide posts 15 arranged at equal intervals. The outer surface of each guide post 15 is slidably connected to a sliding sleeve 16. The outer surface of each sliding sleeve 16 is fixedly connected to the inner wall of the upper mold base 3. Next, guide posts 15 are set on the upper surface of the mounting base 14 to support the guide posts 15. A sliding sleeve 16 is set on the surface of the guide posts 15, and the guide posts 15 and the sliding sleeve 16 are slidably connected to limit the sliding sleeve 16. The sliding sleeve 16 is fixed to the inner wall of the upper mold base 3, so that the upper mold base 3 can rise and fall on the surface of the guide posts 15 through the sliding sleeve 16, thereby ensuring the stability of the upper mold base 3 when rising and falling. A top plate 17 is set above the upper mold base 3. The top of each guide post 15 is fixedly connected to the bottom surface of the top plate 17. The bottom surface of the top plate 17 is fixed to the top of the corresponding guide post 15 to support the top plate 17.

[0036] Please see Figure 4 and Figure 5A die-casting pipe 18 is fixedly installed on the inner wall of the upper mold 1. A feed pipe 19 is fixedly connected to the upper surface of the die-casting pipe 18. The die-casting pipe 18 is installed on the inner wall of the upper mold 1 and fixed. The feed pipe 19 is connected to the upper surface of the die-casting pipe 18 so that the die-casting material inside the feed pipe 19 is input into the interior of the die-casting pipe 18. A conical part 20 is fixedly installed on the inner wall of the lower mold 2. A guide groove 21 is opened on the outer surface of the conical part 20. The conical part 20 is installed on the inner wall of the lower mold 2. When the upper mold 1 and the lower mold 2 are closed, the die-casting pipe 18 and the conical part 20 can be matched. The guide groove 21 is opened on the surface of the conical part 20. Through the conical shape of the conical part 20 and the guide groove 21 on the surface, the die-casting material can enter between the upper mold 1 and the lower mold 2 and flow through the channel between the upper mold 1 and the lower mold 2.

[0037] Please see Figure 1 , Figure 2 and Figure 6 Each water tank 5 has a sealing cover 13 on its upper surface. The sealing cover 13 can be opened to facilitate the replenishment of cooling water into the water tank 5.

[0038] The implementation principle of this application embodiment is as follows: By setting the connection between the guide column 15 and the sliding sleeve 16, the upper mold 1 and the upper mold base 3 are limited, improving the stability of the upper mold 1 and the upper mold base 3 when they are raised and lowered. After the upper mold 1 and the lower mold 2 are closed, the die-casting material is input through the feed pipe 19 and transmitted through the die-casting pipe fitting 18, so that the die-casting material enters the space between the upper mold 1 and the lower mold 2 under the guidance of the conical part 20 and the guide groove 21 until the gap between the upper mold 1 and the lower mold 2 is filled. Then, the first water pump 6 and the second water pump 9 are started, and the water tank 5 on the left side is pumped through the first water pump 6 and the pipe. Cooling water is drawn from the lower mold 2 and the lower mold base 4 and transferred through the first water pipe 7. At this time, the cooling water can remove the heat from the lower mold 2 and the lower mold base 4. The cooling water carrying the heat is discharged through the first drain pipe 8. The cooling water in the right water tank 5 is drawn from the second water pump 9 and the pipeline and transferred through the hose 10 and the second water pipe 11. At this time, the cooling water can remove the heat from the upper mold 1 and the upper mold base 3 and the cooling water carrying the heat is discharged through the second drain pipe 12. Thus, this device can remove the heat during die casting by cooling water, shorten the cooling time of the die casting, accelerate the solidification of the die casting, and improve production efficiency.
