Description

Technical Field

[0001] The utility model relates to the technical field of motor housing processing, and specifically, to a multi-axis positioning die-casting device for an integrated motor housing. Background Technique

[0002] At present, die-casting technology is a process of using high pressure to force molten metal into a metal mold with a complex shape, and then rapidly solidifying under high pressure to obtain precision castings; when die-casting a motor housing, by pouring a high-temperature solution into the mold, and then quickly squeezing and closing the high-temperature solution by turning on the die-casting device, and then cooling and forming to form a finished motor housing.

[0003] For die-casting devices for motor housings, there are many existing technologies, for example:

[0004] Chinese Patent Publication No. CN218452589U discloses a die-casting device for a motor housing, which includes a base, a support column, a top plate, a power device and a die-casting plate; the top of the base is fixedly connected with a support column; the top of the support column is fixedly connected with a top plate; the top of the top plate is fixedly connected with a power device; when the positioning block slides downward, it compresses the positioning groove to generate elastic force, and then turns on the power device to drive the die-casting plate to slide downward, so that the die-casting plate covers the top of the die-casting template for die-casting and forming. When the die-casting is completed, by turning on the pulling unit, the locking block slides out of the locking groove, and then the second spring generates elastic force to push the die-casting template upward, facilitating the machine to hook the corners of the die-casting template to take out the die-casting template from the forming cavity, and then taking out the formed motor housing. This process can reduce the contact between the staff and the formed motor housing and improve the die-casting efficiency of the motor housing.

[0005] It can be seen that most die-casting devices for motor housings form the motor housing by squeezing and closing the die-casting plate and the template. Since the shapes and sizes of motor housings are different, different sizes of die-casting plates and templates need to be replaced. However, the replaced die-casting plates and templates will inevitably deviate, reducing the accuracy of motor housing die-casting, and also affecting the working efficiency of motor housing die-casting. Seriously, it will increase the defective rate of motor housing die-casting production, cause waste of time and increase economic losses, thereby reducing the practicability of the die-casting device for motor housings.

[0006] In view of this, we propose a multi-axis positioning die-casting device for an integrated motor housing. Content of the Utility Model

[0007] The purpose of the present utility model is to solve the above-mentioned drawbacks and provide a multi-axis positioning die-casting device for an integrated motor housing with a positioning component for positioning the downward pressing direction of the template.

[0010] The template is installed on the lower surface of the mounting plate through the installation components. The die-casting plate is installed on the upper surface of the operation table through the installation components. Positioning components are arranged at the four corners of the die-casting plate and the template. The positioning components are used to limit the direction of the downward pressure on the template and improve the accuracy of producing the motor housing by the template and the die-casting plate.

[0011] As a further improvement of the technical solution, the installation components at least include installation grooves. Installation grooves are opened on the lower surface of the mounting plate and the upper surface of the operation table. A two-way cylinder is arranged inside the installation groove. Piston rods at both ends of the two-way cylinder are provided with clamping plates. Fixing plates are arranged below the clamping plates on the side close to the two-way cylinder. Fixing grooves are opened on the lower surface of the die-casting plate and the upper surface of the template.

[0012] As a further improvement of the technical solution, the positioning components at least include four positioning shafts. Positioning holes for sliding connection with the positioning shafts are opened on the four sides of the die-casting plate and the four sides of the template. Fixing components are arranged at both ends of the four positioning shafts.

[0013] As a further improvement of the technical solution, the fixing components at least include multi-stage cylinders. Multi-stage cylinders are arranged inside both ends of the positioning shafts. A piston rod of the multi-stage cylinder is provided with a fixing shaft.

[0026] Most die-casting devices for motor casings form the motor casing by squeezing and closing the die-casting plate and the template. Since the shapes and sizes of the motor casings are different, it is necessary to replace the die-casting plates and templates of different sizes. However, deviations are inevitable in the replaced die-casting plates and templates, which reduces the accuracy of die-casting the motor casing, and also affects the working efficiency of die-casting the motor casing. Seriously, it will increase the defective rate of die-casting the motor casing, cause waste of time, increase economic losses, and thus reduce the practicability of the die-casting device for the motor casing.

[0027] Please refer to Figures 1-4 the embodiment of the present utility model shown in the figure. The device includes an operating table 10. Support columns 11 are provided at the four corners of the upper surface of the operating table 10. A top plate 12 is provided at the top of the support columns 11. A hydraulic cylinder 13 is provided on the lower surface of the top plate 12. A mounting plate 14 is provided on the piston rod of the hydraulic cylinder 13. A template 21 is installed on the lower surface of the mounting plate 14 through an installation component 22. A die-casting plate 20 is installed on the upper surface of the operating table 10 through the installation component 22. Positioning components 30 are provided at the four corners of the die-casting plate 20 and the template 21. The positioning components 30 are used to limit the direction of the downward pressure of the template 21 and improve the accuracy of producing the motor casing by the template 21 and the die-casting plate 20.

[0028] First, the specific structure of the installation component 22 is disclosed. The installation component 22 at least includes an installation groove 221. Installation grooves 221 are provided on both the lower surface of the installation plate 14 and the upper surface of the operation table 10. A double-acting cylinder 222 is arranged inside the installation groove 221. Clamping plates 223 are arranged on the piston rods at both ends of the double-acting cylinder 222. A fixing plate 224 is arranged below the clamping plate 223 on the side close to the double-acting cylinder 222. Fixing grooves 225 are provided on both the lower surface of the die-casting plate 20 and the upper surface of the template 21.

[0029] The improvement lies in: Connect the double-acting cylinder 222 to the power supply to make it work. Through the work of the piston rod of the double-acting cylinder 222 pushing, move the clamping plate 223 towards the inner wall of the installation groove 221. At this time, the fixing groove 225 can be inserted and matched with the clamping plate 223, and through the work of the piston rod of the double-acting cylinder 222 resetting, the fixing groove 225 is clamped. At the same time, the fixing plate 224 enters the innermost part of the fixing groove 225, increasing the stability of the installation of the die-casting plate 20 and the template 21. The installation is convenient, facilitating the replacement of die-casting plates 20 and templates 21 of different sizes, improving the flexibility of the die-casting device in use, reducing the production cost of the die-casting device, and thus improving the practicality of the die-casting device.

[0030] Secondly, the specific structure of the positioning component 30 is disclosed. The positioning component 30 at least includes four positioning shafts 32. Positioning holes 31 for sliding connection with the positioning shafts 32 are provided on the four sides of both the die-casting plate 20 and the template 21. Fixing components 33 are arranged at both ends of the four positioning shafts 32.

[0031] The improvement lies in: Pass the four positioning shafts 32 through the corresponding positioning holes 31 respectively, and install the positioning shafts 32 between the operation table 10 and the top plate 12 through the fixing components 33. The installation and disassembly are convenient, and it also plays a role in positioning during the operation of the die-casting device, improving the accuracy of the die-casting of the motor housing, increasing the yield of the motor housing production, improving the economic benefits, and thus improving the practicality of the die-casting device.

[0032] Thirdly, the specific structure of the fixing component 33 is disclosed. The fixing component 33 at least includes a multi-stage cylinder 331. Multi-stage cylinders 331 are arranged inside both ends of the positioning shaft 32. A fixing shaft 332 is arranged on the piston rod of the multi-stage cylinder 331.

[0033] The improvements are as follows: After the positioning shaft 32 passes through the die-casting plate 20 and the template 21, the multi-stage cylinder 331 is powered on to make it work. Through the pushing work of the multi-stage cylinder 331, the two fixed shafts 332 are respectively moved closer to the upper surface of the operating table 10 and the lower surface of the top plate 12, and are pressed against them, achieving the effect of stabilizing the positioning shaft 32. The operation is simple and the installation is convenient. Similarly, through the reset work of the piston rod of the multi-stage cylinder 331, at this time, the positioning shaft 32 can be taken out from the die-casting plate 20 and the template 21, disconnecting the positioning shaft 32 from the positioning hole 31, which is convenient for replacing die-casting plates 20 and templates 21 of different sizes. This not only improves the flexibility of the die-casting device in use, but also improves the practicality of the die-casting device, reduces production costs, and thus avoids economic losses.

[0034] In order to prevent the positioning shaft 32 from being unstable after installation and affecting the die-casting work of the motor housing, therefore, an anti-slip pad 34 is provided at the end of the fixed shaft 332 away from the multi-stage cylinder 331.

[0035] The improvements are as follows: By providing the anti-slip pad 34, when the fixed shaft 332 contacts the operating table 10 and the top plate 12, it can prevent slipping. This not only improves the stability of the installation of the positioning shaft 32, improves the accuracy of die-casting of the motor housing, but also improves the safety of using the positioning assembly 30, reduces the frequency of work accidents, and thus avoids economic losses.

[0036] In summary, the working principle of this solution is as follows: First, the double-acting cylinder 222 is powered on to make it work. Through the pushing work of the piston rod of the double-acting cylinder 222, the clamping plate 223 is moved towards the inner wall of the installation groove 221. At this time, the fixed groove 225 can be inserted and matched with the clamping plate 223, and through the reset work of the piston rod of the double-acting cylinder 222, the fixed groove 225 is clamped. At the same time, the fixing plate 224 enters the innermost part of the fixed groove 225. After the template 21 is installed, then the four positioning shafts 32 are respectively passed through the four positioning holes 31 on the template 21. Then, the four positioning shafts 32 are respectively passed through the four positioning holes 31 on the die-casting plate 20, and the die-casting plate 20 is installed through the installation component 22. Then, the multi-stage cylinder 331 is powered on to make it work. Through the pushing work of the multi-stage cylinder 331, the two fixed shafts 332 are respectively moved closer to the upper surface of the operating table 10 and the lower surface of the top plate 12, and are pressed against them. Finally, the motor housing can be produced, and the installation work of the die-casting device can be completed.
