Description

Technical Field

[0001] This utility model relates to the technical field of motor housings, specifically a motor housing mold with a T-shaped flow channel. Background Technology

[0002] The motor housing is an important component of the motor. The motor stator and the high-speed rotating rotor are installed inside the motor housing, so the dimensional accuracy and mechanical properties determine the quality of the product.

[0003] For example, an explosion-proof motor housing mold with authorization announcement number "CN212419578U" solves the problem that existing explosion-proof motor housing molds are not easy to guarantee the positional accuracy of the core-pulling mechanism, which easily leads to low accuracy of the inner hole of the die-cast motor housing. The above-mentioned method connects the moving outer mold and the stationary outer mold, inserts the first limiting rod into the first limiting through hole, and then adjusts the position of the second abutting block so that the first limiting rod and the second abutting block are inserted and connected, improving the positional accuracy of the second mold part, thereby improving the inner hole accuracy of the explosion-proof motor housing. Considering the explosion-proof motor housing mold, fixing the channel into which the solution is injected internally makes the flow rate of the solution fixed, and it cannot disperse and flow into various positions in a short time, resulting in a decrease in the filling efficiency of the mold cavity, which will also increase porosity and air bubbles, and reduce production quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing explosion-proof motor housing molds cannot disperse the flow to various positions in a short time, resulting in reduced mold cavity filling efficiency, increased porosity and air bubbles, and reduced production quality. Therefore, a T-shaped flow channel motor housing mold is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a T-shaped flow channel motor housing mold, comprising a base and a support leg, wherein the lower end of the base is fixedly connected to the support leg, the upper end of the base is fixedly connected to an outer mold shell, the upper end of the outer mold shell is fixedly connected to an insertion post, the outer wall of the insertion post is movably connected to a cover plate, the upper end of the insertion post is threadedly connected to a threaded block, the lower end of the threaded block abuts against the cover plate, and a pusher mechanism is connected to the outer wall of the base.

[0006] Preferably, the booster mechanism includes a power cylinder, the lower end of which is fixedly connected to the base, the output end of which is fixedly connected to a fixed block, the outer wall of which is fixedly connected to a push plate, and the outer wall of which is fixedly connected to a first arc-shaped block.

[0007] Preferably, the outer wall of the outer mold shell is fixedly connected to the threaded ring, and the upper end of the base is connected to a T-shaped mechanism.

[0008] Preferably, the T-shaped mechanism includes an intercepting plate, the lower end of which is fixedly connected to the base, the inner wall of which is machined with a T-shaped flow groove, and the inner wall of which is slidably connected to the second arc-shaped block.

[0009] Preferably, the outer wall of the outer mold shell is fixedly connected to the inner threaded cover, and the inner wall of the inner threaded cover is fixedly connected to the inner mold.

[0010] Preferably, the upper end of the base is fixedly connected to the outer mold.

[0011] Preferably, the lower end of the base is connected to the injection molding tube, and a flow valve is installed on the outer wall of the injection molding tube.

[0012] The present invention proposes a T-shaped flow channel motor housing mold, which has the following advantages: the molten aluminum alloy raw material is injected into the cavity of the outer mold shell through the mold, and the power cylinder pushes the push plate on the fixed block to move, so that the push plate pushes the aluminum alloy raw material to the interception plate. The T-shaped flow channel disperses the flow of aluminum alloy raw material into the inner mold and the outer mold, thereby improving the mold cavity filling efficiency, reducing air holes and bubbles, and improving the production quality.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figure 1-6 In this embodiment, a T-shaped flow channel motor housing mold includes a base 1 and a support leg 2. The lower end of the base 1 is fixedly connected to the support leg 2, the upper end of the base 1 is fixedly connected to the outer mold shell 3, the upper end of the outer mold shell 3 is fixedly connected to the insertion post 4, the outer wall of the insertion post 4 is movably connected to the cover plate 5, the upper end of the insertion post 4 is threadedly connected to the threaded block 6, the lower end of the threaded block 6 abuts against the cover plate 5, and the outer wall of the base 1 is connected to a boosting mechanism 7.

[0023] The boosting mechanism 7 includes a power cylinder 701, which pushes the push plate 703 on the fixed block 702 to move, so that the push plate 703 pushes the aluminum alloy material to the intercepting plate 901, so that the push plate 703 has the effect of boosting the solution inside the outer mold shell 3. The lower end of the power cylinder 701 is fixedly connected to the base 1. The model of the power cylinder 701 is determined according to actual requirements, as long as it meets the working requirements. The output end of the power cylinder 701 is fixedly connected to the fixed block 702. The outer wall of the fixed block 702 is fixedly connected to the push plate 703. The outer wall of the push plate 703 is fixedly connected to the first arc-shaped block 704.

[0024] The outer wall of the outer mold shell 3 is fixedly connected to the threaded ring 8. The upper end of the base 1 is connected to a T-shaped mechanism 9. The aluminum alloy raw material flows into the inner mold 11 and the outer mold 12 through the T-shaped flow channel 902 to disperse the flow and accelerate the flow area of ​​the solution. The T-shaped mechanism 9 includes an intercepting plate 901. The lower end of the intercepting plate 901 is fixedly connected to the base 1. The inner wall of the intercepting plate 901 is machined with a T-shaped flow channel 902. The inner wall of the intercepting plate 901 is slidably connected to the second arc-shaped block 903.

[0025] The molten aluminum alloy material is injected into the cavity of the outer mold shell 3. The power cylinder 701 pushes the push plate 703 on the fixed block 702 to move, so that the push plate 703 pushes the aluminum alloy material to the intercepting plate 901. The T-shaped flow channel 902 disperses the aluminum alloy material flowing into the inner mold 11 and the outer mold 12, improving the mold cavity filling efficiency, reducing air holes and bubbles, and improving production quality.

[0026] The outer wall of the outer mold shell 3 is fixedly connected to the inner threaded cover 10, the inner wall of the inner threaded cover 10 is fixedly connected to the inner mold 11, the upper end of the base 1 is fixedly connected to the outer mold 12, the lower end of the base 1 is connected to the injection tube 13, and a flow valve 14 is installed on the outer wall of the injection tube 13. The flow valve 14 is a 650℃ ultra-high temperature explosion-proof solenoid valve.

[0027] Working principle:

[0028] By disassembling the threaded block 6 on the plug-in post 4 and removing the cover plate 5 on the outer mold shell 3, the cavity inside the outer mold shell 3 can be cleaned. The cover plate 5 then seals the upper end of the outer mold shell 3 again. The flow rate is controlled by the flow valve 14 on the injection pipe 13, allowing the aluminum alloy material to be injected into the cavity of the outer mold shell 3. The power cylinder 701 is activated, pushing the push plate 703 on the fixed block 702 to move, causing the push plate 703 to push the aluminum alloy material against the interceptor plate 901. Through the T-shaped flow channel 902, the aluminum alloy material flows more dispersed between the inner mold 11 and the outer mold 12, preventing uneven flow of the aluminum alloy material from causing air bubbles in the molding motor housing. During the process, aluminum alloy raw materials are attached to the inner wall of the outer mold 12 and the outer wall of the inner mold 11 to form a motor housing. Since the inner wall of the motor housing and the outer wall of the inner mold 11 are in a smooth and fitted molding relationship, when the inner thread cover 10 is twisted and separated from the threaded ring 8, and the inner thread cover 10 is pulled, the inner mold will be driven to detach from the inside of the already formed motor housing. At this time, the power cylinder 701 continues to push the push plate 703 on the fixed block 702 to move. The second arc block 903 on the push plate 703 will push the first arc block 704 to press the outer edge of the motor housing. The outer wall of the motor housing is separated from the inner wall of the outer mold 12, so that the formed motor housing can be taken out from the inside of the outer mold housing 3.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
