Description

Technical Field

[0001] The present application relates to the technical field of explosion-proof motors, and in particular to a casting and molding device for an end cover of an explosion-proof motor. Background Art

[0002] A motor refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction, or converts one form of electrical energy into another. The motor is composed of a casing, a stator, a rotor and other parts. It rotates by generating different magnetic fields when the stator and rotor are energized. Generally, end covers are installed at both ends of the motor casing to fix and support the rotor shaft. The material of the motor end covers is mostly metal, and they are generally cast when produced.

[0003] The prior art also proposes an improved solution for the casting of motor end covers. For example, the application with publication number CN114951558A discloses a motor end cover casting mold, which relates to the field of motor end cover production technology, wherein the casting mold includes: a mold body; a demoulding assembly, which is installed on the outside of the mold body; wherein the demoulding assembly includes a telescopic rod, and the telescopic end of the telescopic rod is connected to a demoulding piece; the demoulding piece includes an electromagnetic plate and a movable plate, and the electromagnetic plate and the movable plate are connected by a spring. Since the demoulding assembly is installed externally and the interior of the mold is not modified, the technical problem that the demoulding of the existing motor end cover casting mold is cumbersome and requires subsequent processing during use is effectively solved, thereby achieving stable mold closing, and at the same time preventing the demoulding assembly from affecting the normal formation of the workpiece during mold closing.

[0004] Although the above technical solution solves the problem of stable mold closing, there are still other problems in specific use. After the motor end cover is formed, the upper mold base is generally opened, and then the staff manually assists in removing the end cover formed in the lower mold base. Since the end cover is too adhered to the lower mold base, it is difficult to operate when removing it.

[0005] Therefore, it is necessary to provide a casting molding device for an explosion-proof motor end cover to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] like Figure 1-Figure 4 As shown, the present application provides an explosion-proof motor end cover casting molding device, including a working bracket 1, a driving wheel 2 is rotatably installed on the top of the working bracket 1, and the end of the driving wheel 2 is connected to the output end of the external motor, a support rod 101 is fixedly installed on the side wall of the working bracket 1, and a liquid storage seat 3 is fixedly installed below the support rod 101, and multiple groups of mounting frames 4 are fixedly installed on the outer peripheral surface of the driving wheel 2, and a casting frame 5 is rotatably arranged between each group of mounting frames 4, and an upper mold base 501 and a lower mold base 502 are arranged above the casting frame 5, and the upper mold base 501 and the lower mold base 502 form a motor end cover cavity when combined, and a control mechanism is arranged below the liquid storage seat 3, and the control mechanism is used to pass molten liquid into the upper mold base 501 and the lower mold base 502, and a discharging mechanism is arranged inside the casting frame 5, and the discharging mechanism is used to automatically discharge the formed motor end cover;

[0037] When working, refer to the attached Figure 1As shown, at this time, the lower mold base 502 and the upper mold base 501 are combined together, and then the motor is controlled to drive the driving wheel 2 to rotate, so that the driving wheel 2 drives one group of mounting frames 4 and the casting frame 5 to move to the side close to the liquid storage seat 3. When the upper mold base 501 of one group of casting frames 5 is aligned with the liquid outlet of the liquid storage seat 3, under the action of the control mechanism, the driving wheel 2 is first controlled to stop running, and the molten liquid inside the liquid storage seat 3 can be passed into the liquid inlet of the upper mold base 501, and then flows into the cavity between the upper mold base 501 and the lower mold base 502. Then the driving wheel 2 is controlled to rotate. When the upper mold base 501 and the lower mold base 502 containing the molten liquid move to the left side of the working bracket 1, the molten liquid is just formed at this time. Then, under the action of the discharging mechanism, the formed motor end cover can be automatically discharged. With this design, the motor end cover can be produced continuously, and it can also be discharged automatically, avoiding manual assisted discharging by staff, and the operation is more convenient.

[0038] like Figure 2-Figure 5 As shown, the control mechanism includes a contact 1 6 fixedly mounted below the liquid storage seat 3, and a contact 2 7 is installed on the side wall of each group of the casting frames 5. The casting frames 5 will contact with the contact 1 6 during rotation; during operation, when the casting frame 5 rotates following the mounting frame 4 and the driving wheel 2, the casting frame 5 will simultaneously drive the contact 2 7 to rotate, and when the casting frame 5 rotates to one side of the liquid storage seat 3, the contact 1 6 and the contact 2 7 will contact, so that the external circuit is connected and the controller will control the driving wheel 2 to stop running, and at the same time, the molten liquid inside the liquid storage seat 3 will automatically pass into the upper mold seat 501, thereby realizing the automatic introduction of the molten liquid, and the operation is relatively convenient.

[0039] The casting frame 5 is rotatably arranged between two adjacent mounting frames 4 through a rotating rod. The casting frame 5 is in an arc shape, and a gravity ball 503 is installed at the lowest point of the arc.

[0040] During operation, since the casting frame 5 rotates between the two mounting frames 4 and under the action of the bottom gravity ball 503, the entire casting frame 5 can be kept in a vertical state, that is, the driving wheel 2 will not affect the state of the casting frame 5 during rotation, which makes it convenient to remove the formed motor end cover later and facilitates the continuous casting of the motor end cover, thereby improving the motor forming efficiency.

[0041] The side wall of the support rod 101 is fixedly installed with a connecting frame 8, and contact three 9 is installed at the position corresponding to contact two 7 on the surface of the connecting frame 8; during operation, when the upper mold base 501 and the lower mold base 502 containing the molten liquid are away from the liquid storage base 3, contact one 6 and contact two 7 are in contact, and the liquid storage base 3 stops working at this time, and with the rotation of the driving wheel 2, the upper mold base 501 and the lower mold base 502 containing the molten liquid move to the left side of the working bracket 1, at this time, contact two 7 on the side wall of the casting frame 5 will contact contact three 9, and the molten liquid is just formed. Under the contact between contact two 7 and contact three 9, the external circuit is connected, thereby controlling the discharging mechanism to automatically discharge the formed motor end cover, avoiding the problem that the formed motor end cover is too adhered to the inner wall of the upper mold base 501 and the lower mold base 502, which makes it difficult to remove the motor end cover later.

[0042] like Figure 4-Figure 8 As shown, the discharging mechanism includes a vertical rod 10 installed on the side wall of the casting frame 5, two vertical rods 10 are provided, and are symmetrically arranged relative to the casting frame 5, the opposite surfaces of the two vertical rods 10 are fixedly installed with a fixing seat 11, the insides of the two fixing seats 11 are slidably installed with an electric telescopic rod 12, the upper mold base 501 is fixedly installed between the two electric telescopic rods 12, and the outer side of the lower mold base 502 is provided with a ejection unit, and the ejection unit is used to automatically eject the formed motor end cover;

[0043] During operation, when contact two 7 and contact three 9 are in contact, the external circuit is connected, and the controller controls the electric telescopic rod 12 to drive the upper mold base 501 to move upward, so that the upper mold base 501 is away from the lower mold base 502. During the movement of the upper mold base 501, the ejecting unit on the outside of the lower mold base 502 will automatically eject the formed motor end cover to avoid the problem that the formed motor end cover is too adhered to the inner wall of the mold base, making it difficult to remove it.

[0044] like Figure 4-Figure 10 The ejecting unit shown includes a top plate 13 slidably arranged on the lower die seat 502, the diameter of the top plate 13 is adapted to the diameter of the lower die seat 502, a ejector rod 14 is slidably arranged inside the casting frame 5, the top end of the ejector rod 14 is connected to the bottom end of the top plate 13, a limit spring 15 is fixedly arranged below the ejector rod 14, the limit spring 15 is installed on the inner wall of the casting frame 5, a plurality of groups of fixed pulleys 16 are rotatably arranged inside the casting frame 5 through the mounting bracket 504, the outer surface of each group of fixed pulleys 16 is surrounded by an elastic pull rope 17, a limit arc plate 18 is slidably arranged inside the casting frame 5 through a support rod, a limit groove 131 is provided on the side wall of the ejector rod 14, the shape of the limit arc plate 18 is adapted to the shape of the limit groove 131, one end of the elastic pull rope 17 is connected to the surface of the limit arc plate 18, and the other end is connected to the side wall of the upper die seat 501 through the fixed pulley 16;

[0045] During operation, in the initial state, that is, when the upper die seat 501 and the lower die seat 502 are closed to each other, the limit arc plate 18 is located in the limit groove 131, and the limit spring 15 is in a pressure storage state; when the contact two 7 and the contact three 9 are in contact, that is, when the upper die seat 501 is away from the lower die seat 502, the upper die seat 501 will simultaneously pull the elastic pull rope 17 on its side wall, and then the elastic pull rope 17 will pull the limit arc plate 18 at the other end through the fixed pulley 16, so that the limit arc plate 18 is gradually pulled to the side away from the limit groove 131, and then the limit arc plate 18 is away from the limit groove 131. In the pressure storage state, the limit spring 15 is restored by elastic force, and will drive the ejector rod 14 to move up at a higher speed, so that the ejector rod 14 drives the top plate 13 to move up at a higher speed, and then the top plate 13 will drive the formed motor end cover to move out of the lower die seat 502, realizing the function of automatically ejecting it, which is convenient for subsequent re-operation.

[0046] The side wall of the limiting arc plate 18 is provided with a telescopic arc block 181, and the outer surface of the telescopic arc block 181 is sleeved with a telescopic spring 182, and the shape of the telescopic arc block 181 is adapted to the shape of the limiting groove 131; when working, the telescopic spring 182 is provided, which can make the telescopic arc block 181 tightly stuck in the limiting groove 131, which is convenient for the molding of the upper mold base 501 and the lower mold base 502, and can also facilitate the subsequent removal of the molded motor end cover.

[0047] The casting frame 5 is provided with a limiting slide rod adapted to the push rod 14 and the limiting arc plate 18, and the outer walls of the push rod 14 and the limiting arc plate 18 are provided with a limiting slide groove adapted to the limiting slide rod; such a design can facilitate the movement of the push rod 14 on the axis, thereby ensuring that the push rod 14 drives the top plate 13 to move upward and pushes out the motor end cover.

[0048] The lower end surface of the top plate 13 is fixedly mounted with an L-shaped limit rod 19, the outer surface of the L-shaped limit rod 19 is provided with a rectangular groove 20, and the side wall of the upper die seat 501 is mounted with a linkage rod 21, and the side of the linkage rod 21 away from the upper die seat 501 is slidably arranged in the rectangular groove 20; when working, refer to the attached Fig.10As shown, when the upper die seat 501 moves upward, the linkage rod 21 on the side wall of the upper die seat 501 will not contact the upper groove wall of the rectangular groove 20, and there is still a distance between the linkage rod 21 and the lower groove wall of the rectangular groove 20. When the top plate 13 follows the top rod 14 to move upward, the distance between the linkage rod 21 and the lower groove wall of the rectangular groove 20 is just enough to eject the formed motor end cover mold; after the motor end cover mold is taken out, the upper die seat 501 is controlled to move downward, so that the upper die seat 501 drives the linkage rod 21 to move downward, and then the linkage rod 21 contacts the lower groove wall of the rectangular groove 20, and drives the top plate 13 to move downward, so that the top plate 13 drives the top rod 14 and the limit spring 15 to move downward, until the telescopic arc block 181 is again stuck in the limit groove 131, and the limit spring 15 is in a pressure storage state, so it is convenient for the subsequent re-casting of the motor end cover.

[0049] The shape of the rectangular groove 20 is matched with the shape of the end of the linkage rod 21. When working, such a setting can facilitate the linkage rod 21 to drive the L-shaped limit rod 19 and the top plate 13 to move downward, which is convenient for the subsequent re-casting of the motor end cover.

[0050] Working principle: Refer to the attached Figure 1 As shown, at this time, the lower mold base 502 and the upper mold base 501 are combined together, and then the motor is controlled to drive the driving wheel 2 to rotate, so that the driving wheel 2 drives one group of mounting frames 4 and the casting frame 5 to move to the side close to the liquid storage seat 3. When the upper mold base 501 of one group of casting frames 5 is aligned with the liquid outlet of the liquid storage seat 3, under the action of the control mechanism, the driving wheel 2 is first controlled to stop running, and the molten liquid inside the liquid storage seat 3 can be passed into the liquid inlet of the upper mold base 501, and then flows into the cavity between the upper mold base 501 and the lower mold base 502. Then the driving wheel 2 is controlled to rotate. When the upper mold base 501 and the lower mold base 502 containing the molten liquid move to the left side of the working bracket 1, at this time The molten liquid is just formed, and then the formed motor end cover can be automatically discharged under the action of the discharge mechanism. Such a design can continuously produce the motor end cover, and can also automatically discharge, avoiding the manual assistance of the staff to discharge, and the operation is more convenient; when the casting frame 5 rotates with the mounting frame 4 and the driving wheel 2, the casting frame 5 will drive the contact 2 7 to rotate at the same time. When the casting frame 5 rotates to one side of the liquid storage seat 3, the contact 1 6 and the contact 2 7 will contact, so that the external circuit is connected and the controller will control the driving wheel 2 to stop running. At the same time, the molten liquid inside the liquid storage seat 3 will automatically pass into the upper mold seat 501, realizing the automatic introduction of the molten liquid, and the operation is more convenient;

[0051] When the upper die seat 501 and the lower die seat 502 containing the molten liquid are away from the liquid storage seat 3, the contact 1 6 and the contact 2 7 are in contact, and the liquid storage seat 3 stops working at this time. With the rotation of the driving wheel 2, the upper die seat 501 and the lower die seat 502 containing the molten liquid move to the left side of the working bracket 1. At this time, the contact 2 7 on the side wall of the casting frame 5 will contact the contact 3 9, and the molten liquid is just formed. Under the contact between the contact 2 7 and the contact 3 9, the external circuit is connected, so that the discharging mechanism will be controlled to automatically discharge the formed motor end cover, so as to avoid the problem that the formed motor end cover is too adhered to the inner wall of the upper die seat 501 and the lower die seat 502, which makes it difficult to remove the motor end cover later.

[0052] When the upper die seat 501 and the lower die seat 502 are in the initial state, that is, when the upper die seat 501 and the lower die seat 502 are closed to each other, the limit arc plate 18 is located in the limit groove 131, and the limit spring 15 is in the pressure storage state; when the contact point 2 7 and the contact point 3 9 are in contact, that is, when the upper die seat 501 is away from the lower die seat 502, the upper die seat 501 will simultaneously pull the elastic pull rope 17 of its side wall, and then the elastic pull rope 17 will pull the limit arc plate 18 at the other end through the fixed pulley 16, so that the limit arc plate 18 is gradually pulled to the side away from the limit groove 131, and then the limit arc plate 18 is away from the limit groove 131. In the pressure storage state, the limit spring 15 will restore through elastic force, and will drive the ejector rod 14 to move up at a higher speed, so that the ejector rod 14 drives the top plate 13 to move up at a higher speed, and then the top plate 13 will drive the formed motor end cover to move out of the lower die seat 502, realizing the function of automatically ejecting it, which is convenient for subsequent re-operation of it; refer to the attached Fig.10 As shown, when the upper die seat 501 moves upward, the linkage rod 21 on the side wall of the upper die seat 501 will not contact the upper groove wall of the rectangular groove 20, and there is still a distance between the linkage rod 21 and the lower groove wall of the rectangular groove 20. When the top plate 13 follows the top rod 14 to move upward, the distance between the linkage rod 21 and the lower groove wall of the rectangular groove 20 is just enough to eject the formed motor end cover mold; after the motor end cover mold is taken out, the upper die seat 501 is controlled to move downward, so that the upper die seat 501 drives the linkage rod 21 to move downward, and then the linkage rod 21 contacts the lower groove wall of the rectangular groove 20, and drives the top plate 13 to move downward, so that the top plate 13 drives the top rod 14 and the limit spring 15 to move downward, until the telescopic arc block 181 is again stuck in the limit groove 131, and the limit spring 15 is in a pressure storage state, so it is convenient for the subsequent re-casting of the motor end cover.

[0053] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
