A thermostat base casting device

Abstract

This utility model discloses a thermostat seat casting device, relating to the field of thermostat technology. The utility model includes a base, a mold, and a robotic arm, as well as a lifting mechanism, a spraying mechanism, and a transmission assembly. The utility model uses the elastic force of a limiting spring to pull a limiting component to slide, inserting it into the limiting groove of a rotating cylinder, thus limiting and fixing the rotating cylinder and preventing it from rotating inside the slider. At this time, the motor drives the screw to rotate, which in turn drives the slider and the rotating cylinder to slide up and down along the inside of the sliding sleeve, driving the spraying mechanism to move up and down. Adjusting the spraying mechanism to the die-casting cavity of the mold or away from the mold, the limiting component is magnetically pulled by an electromagnet, overcoming the elastic force of the rotating cylinder and disengaging from the limiting groove. The rotating cylinder can then rotate freely inside the slider. At this time, the motor drives the screw to rotate, which in turn drives the transmission wheel at the top of the rotating cylinder to rotate. Through the transmission wheel and the transmission belt, the transmission wheel at the top of the support plate rotates.

Description

Technical Field

[0001] This utility model relates to the field of thermostat technology, specifically to a thermostat seat casting device. Background Technology

[0002] The thermostat is a key component in the automotive engine cooling system. It can adjust the amount of water entering the radiator according to the temperature of the coolant, change the water circulation range, and adjust the heat dissipation capacity of the cooling system. Its housing is mass-produced using a die-casting process.

[0003] In the die-casting production process, after each die-casting cycle, the mold cavity surface needs to be cleaned and sprayed with a release agent to remove residual aluminum shavings and oil stains, ensuring smooth demolding of the castings in the next cycle. A sprayer is commonly used for this task. After the die-casting mold is removed and the robotic arm takes it off, atomized release agent solution is sprayed onto the mold cavity surface through multiple densely arranged nozzles of the sprayer.

[0004] To ensure that the water flow or droplets sprayed from a large number of nozzles can fully and effectively cover the complex-shaped thermostat seat mold cavity, a large number of nozzles are usually required on the sprayer. However, the surge in the number of nozzles leads to a significant increase in the total flow rate required per unit time, necessitating the use of a pump system with greater power and higher output pressure. Furthermore, nozzles are prone to clogging in the sprayer, as scale, mold release agent residue, aluminum slag, and other substances in the die-casting environment can easily clog the tiny spray holes of the nozzles. Daily inspection of the working status of each nozzle is tedious and time-consuming. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a thermostat seat casting device, which solves the issues of the large number of nozzles required, increased output pressure demand, and cumbersome and time-consuming daily maintenance during the casting of thermostat seats.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a thermostat seat casting device, including a base, a mold and a robotic arm, and further including a lifting mechanism, a spraying mechanism and a transmission component. The top left and right sides of the base are provided with a horizontally movable mold, the top rear side of the base is fixedly installed with a robotic arm, the top front side of the base is fixedly installed with a lifting mechanism, the moving end of the lifting mechanism is fixedly connected to the spraying mechanism, and the inside of the spraying mechanism is provided with a transmission component.

[0007] The lifting mechanism includes a motor, a screw, and a rotating drum. The output end of the motor is fixedly connected to the screw, and the rotating drum is threaded onto the surface of the screw.

[0008] The spraying mechanism includes a support plate, a nozzle component, a fixing ring, and a collar. The collar is fixedly installed on the top of the support plate, and the fixing ring is fixedly installed on the top of the nozzle component. The fixing ring is rotatably installed inside the collar.

[0009] The collar and the rotating drum are connected by a transmission assembly for transmission.

[0010] The lifting mechanism also includes a fixed frame, a sliding sleeve, a slider, and a limiting groove. The fixed frame is fixedly installed on the top front side of the base, and the sliding sleeve is fixedly installed on the bottom of the fixed frame. The motor is located on the top of the fixed frame and is rotatably connected to the sliding sleeve. The slider is slidably installed on the surface of the rotating cylinder, and the slider fits against the inner wall of the sliding sleeve. A limiting groove is opened on the surface of the rotating cylinder.

[0011] The spraying mechanism also includes a delivery pipe, a deflector plate, and a return spring. The support plate is fixedly installed on the moving end surface of the lifting mechanism. The delivery pipe passes through the fixed ring and is connected to the nozzle. The deflector plate is fixedly installed on the surface of the fixed ring. One end of the return spring is fixedly connected to the top of the support plate, and the other end is rotatably connected to the bottom of the deflector plate.

[0012] The transmission assembly includes a transmission wheel, a transmission belt, and a push plate. There are two sets of transmission wheels. One set of transmission wheels is fixedly sleeved on the top of the rotating drum, and the other set of transmission wheels is rotatably mounted on the top of the support plate. The transmission belt is sleeved on the surface of the two sets of transmission wheels and is meshed with them. A push plate is fixedly installed on the top of the transmission wheel located on the support plate.

[0013] The transmission assembly also includes an electromagnet, a limiting member, and a limiting spring. The electromagnet is disposed inside the support plate, the limiting member is slidably installed inside the support plate, and the limiting spring is sleeved on the surface of the limiting member, with one end connected to the inner wall of the support plate and the other end connected to the limiting member.

[0014] The limiting component consists of a rod, an adsorption block, and a limiting insert. An adsorption block is fixedly installed at the end of the rod near the electromagnet, and a limiting insert is fixedly installed at the end of the rod near the rotating drum.

[0015] The nozzles on the surface of the nozzle component are arranged at equal intervals along the vertical direction, and the vertical spray range covers the die-casting cavity of the thermostat seat of the mold.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention utilizes the elastic force of a limiting spring to slide a limiting component into the limiting groove of a rotating cylinder, thus limiting and fixing the cylinder and preventing it from rotating inside the slider. At this time, the motor drives the screw to rotate, which in turn drives the slider and the rotating cylinder to slide up and down along the inside of the sliding sleeve, causing the spraying mechanism to move vertically. The spraying mechanism can be adjusted to the die-casting cavity of the mold or away from the mold. An electromagnet magnetically pulls the limiting component, causing it to overcome the elastic force of the rotating cylinder and disengage from the limiting groove. The rotating cylinder can then rotate freely inside the slider. The motor then drives the screw to rotate, which in turn drives the transmission wheel at the top of the rotating cylinder. Through the transmission wheel and the transmission belt, the transmission wheel at the top of the support plate rotates. The push plate pushes the deflector plate to overcome the traction of the return spring, causing the nozzle component to rotate until the push plate and deflector plate separate. The return spring pulls the nozzle component back to its original position. The combined pushing action of both components causes the nozzle component to oscillate continuously, ensuring that even a single row of nozzles can still provide sufficient spraying treatment to the mold. This reduces the number of nozzles while maintaining normal equipment operation and minimizing daily maintenance workload. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0026] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 6 The present invention will be further described below.

[0027] A thermostat seat casting device includes a base 1, a mold 2, and a robotic arm 3. It also includes a lifting mechanism 4, a spraying mechanism 5, and a transmission assembly 6. The mold 2, which can move horizontally, is located on the left and right sides of the top of the base 1. The robotic arm 3 is fixedly installed on the rear side of the top of the base 1. The lifting mechanism 4 is fixedly installed on the front side of the top of the base 1. The moving end of the lifting mechanism 4 is fixedly connected to the spraying mechanism 5. The transmission assembly 6 is located inside the spraying mechanism 5. The lifting mechanism 4 includes a motor 403, a screw 404, and a rotating drum 406. The output end of the motor 403 is fixedly connected to the screw 404, and the rotating drum 406 is threaded onto the surface of the screw 404. The spraying mechanism 5 includes a support plate 501, a nozzle 502, a fixing ring 504, and a collar 505. The collar 505 is fixedly installed on the top of the support plate 501, and the fixing ring 504 is fixedly installed on the top of the nozzle 502. The fixing ring 504 is rotatably installed inside the collar 505. The collar 505 and the rotating drum 406 are connected and driven by the transmission assembly 6.

[0028] Specifically, the thermostat seat is removed from the die-cast mold 2 by the robotic arm 3, and the spraying mechanism 5 is moved up and down by the lifting mechanism 4. The spraying mechanism 5 sprays water mist into the cavity of the mold 2. The lifting power of the lifting mechanism 4 is changed by the transmission component 6, thereby driving the spraying end of the spraying mechanism 5 to rotate.

[0029] The lifting mechanism 4 also includes a fixed frame 401, a sliding sleeve 402, a slider 405, and a limiting groove 407. The fixed frame 401 is fixedly installed on the top front side of the base 1. The sliding sleeve 402 is fixedly installed on the bottom of the fixed frame 401. The motor 403 is located on the top of the fixed frame 401. The motor 403 is rotatably connected to the sliding sleeve 402. The slider 405 is slidably installed on the surface of the rotating cylinder 406. The slider 405 is in contact with the inner wall of the sliding sleeve 402. The limiting groove 407 is opened on the surface of the rotating cylinder 406, and the limiting groove 407 is correspondingly set with the limiting member 605.

[0030] Specifically, the screw 404 is driven to rotate by the motor 403. When the slider 405 and the rotating drum 406 are connected and fixed by the limiting member 605, the slider 405 moves up and down against the surface of the sliding sleeve 402. When the slider 405 and the rotating drum 406 are slidably connected, the rotating drum 406 rotates freely inside the slider 405. The fixed connection or sliding connection between the slider 405 and the rotating drum 406 is switched and controlled by the connection between the limiting groove 407 and the limiting member 605.

[0031] The spraying mechanism 5 also includes a delivery pipe 503, a deflector plate 506, and a return spring 507. The support plate 501 is fixedly installed on the surface of the slider 405. The delivery pipe 503 passes through the fixing ring 504 and is connected to the nozzle 502. The deflector plate 506 is fixedly installed on the surface of the fixing ring 504. One end of the return spring 507 is fixedly connected to the top of the support plate 501, and the other end is rotatably connected to the bottom of the deflector plate 506.

[0032] Specifically, the spray liquid is delivered to the nozzle 502 via the conveying pipe 503 connected to the pump, and sprays the mold 2. The nozzle 502 is supported to rotate stably at the bottom of the support plate 501 by the sliding of the fixing ring 504 inside the collar 505. The return spring 507 pulls the lever 506, so that the nozzle 502 is tilted in the opposite direction to the push plate 603.

[0033] The transmission assembly 6 includes a transmission wheel 601, a transmission belt 602, and a push plate 603. There are two sets of transmission wheels 601. One set of transmission wheels 601 is fixedly sleeved on the top of the rotating drum 406, and the other set of transmission wheels 601 is rotatably mounted on the top of the support plate 501. The transmission belt 602 is sleeved on the surface of the two sets of transmission wheels 601 and is meshed with them. The push plate 603 is fixedly installed on the top of the transmission wheel 601 located at the support plate 501. The push plate 603 is correspondingly arranged with the push plate 506.

[0034] Specifically, the rotation of the drum 406 is caused by the transmission of the transmission wheel 601 and the transmission belt 602, which drives the push plate 603 to rotate. The push plate 603 then drives the dial plate 506 to rotate the fixed ring 504.

[0035] The transmission assembly 6 also includes an electromagnet 604, a limiting member 605, and a limiting spring 606. The electromagnet 604 is disposed inside the support plate 501. The limiting member 605 is slidably installed inside the support plate 501, and one end of it passes through the support plate 501 to the inside of the slider 405, and is slidably inserted into the limiting groove 407. The limiting spring 606 is sleeved on the surface of the limiting member 605, one end of which is connected to the inner wall of the support plate 501, and the other end is connected to the limiting member 605.

[0036] Specifically, the limiting spring 606 pushes the limiting member 605 to slide into the limiting groove 407 of the rotating drum 406, and the slider 405 and the rotating drum 406 maintain a fixed connection. The electromagnet 604 magnetically pulls the limiting member 605, causing it to overcome the elastic force of the limiting spring 606 and disengage from the limiting groove 407, while the slider 405 and the rotating drum 406 maintain a sliding connection.

[0037] The limiting component 605 consists of a rod 6051, an adsorption block 6052, and a limiting insert 6053. The adsorption block 6052 is fixedly installed at one end of the rod 6051 near the electromagnet 604, and the limiting insert 6053 is fixedly installed at one end of the rod 6051 near the rotating drum 406.

[0038] Specifically, the adsorption block 6052 is magnetically pulled by the electromagnet 604, thereby pulling the limiting member 605 to slide inside the support plate 501. The limiting insert 6053 is inserted into the limiting groove 407 to restrict the rotation of the rotating cylinder 406 inside the slider 405.

[0039] The nozzles on the surface of the nozzle component 502 are arranged at equal intervals along the vertical direction, and the vertical spray range covers the thermostat seat die-casting cavity of the mold 2.

[0040] Specifically, the vertically arranged nozzles cover the die-casting cavity of the mold 2 in the vertical direction. When the nozzle 502 is driven by the transmission component 6 to swing back and forth, it covers the die-casting cavity of the mold 2 in the horizontal direction.

[0041] In summary: When using this utility model, after the operator completes the die-casting of the thermostat seat by operating mold 2, the two sets of molds 2 are separated and the die-cast product is removed by robotic arm 3. To clean the die-casting cavity of mold 2, drive motor 403 drives screw 404 to rotate. At this time, limit spring 606 pushes limit member 605 into the limit groove 407. Slider 405 and rotating cylinder 406 are in a fixed connection state. The rotating screw 404 drives slider 405 and rotating cylinder 406 to move downward against the inner wall of sliding sleeve 402, adjusting the height position of spray mechanism 5 so that the nozzle of nozzle 502 faces the die-casting cavity of mold 2. Electromagnet 604 is activated to magnetically pull limit member 605, causing limit spring 606 to be pulled and extended, and limit member 605 to disengage from the limit. Inside the groove 407, the slider 405 and the rotating drum 406 are in a sliding connection state. The drive motor 403 drives the screw 404 to rotate, the screw 404 drives the rotating drum 406 to rotate, and the rotating drum 406 drives the transmission wheel 601 at its top to rotate. Through the transmission wheel 601 and the transmission belt 602, the transmission wheel 601 located at the top of the support plate 501 is driven to rotate, so that the push plate 603 rotates and pushes the dial plate 506 to overcome the elastic force of the return spring 507, and drives the fixed ring 504 to rotate inside the collar 505 until the push plate 603 and the dial plate 506 separate. The return spring 507 then pulls the fixed ring 504 to reset, so that the nozzle 502 at the bottom of the fixed ring 504 swings back and forth, and delivers the sprayed water mist to fully cover the die-casting cavity of the mold 2, completing the required cleaning work.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
