Technical Field
[0001] This utility model relates to the field of mold cleaning technology, specifically a mold cleaning device. Background Technology
[0002] With technological advancements and improved living standards, automobiles have become a common part of everyday life. To enhance driving safety and protect drivers and passengers, airbags are generally installed in vehicles to protect them in the event of a dangerous situation. An airbag assembly mainly consists of the airbag, a gas generator, and an igniter. The gas generator typically includes a diffuser. The diffuser guides the gas generated in the gas generator into the airbag to inflate it. The diffuser is generally formed by stamping and stretching, and after stamping and stretching, it requires side punching.
[0003] Based on the above, the inventors have discovered the following problem: after the diffuser is side-punched, there may be residual debris in the die cavity and inner wall of the die holder. Before cleaning, the debris in the die cavity of the die holder needs to be cleaned manually, and then it is placed in the cleaning tank for cleaning. Manual cleaning of debris is slow, thereby reducing the cleaning efficiency of the die holder.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a mold cleaning device in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a mold cleaning device to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A mold cleaning device includes a cleaning component, a placement component, a cleaning component, and a rinsing component. The cleaning component includes a pair of hydraulic rods, with a mounting plate installed between the movable ends of the pair of hydraulic rods. An adsorption cylinder is installed at the bottom end of the mounting plate, and the outer wall of the adsorption cylinder has several adsorption ports arranged in a ring at equal intervals. A negative pressure box is installed on the top surface of the mounting plate, and a connecting pipe is connected to one side of the negative pressure box. The connecting pipe passes through the mounting plate at the end away from the negative pressure box and is connected to the adsorption cylinder. A negative pressure fan is installed between the upper and lower ends of the negative pressure box. A cavity is opened on one side of the negative pressure box, and filter screens are installed on both sides of the negative pressure fan and inside the cavity. A door is hinged to the back of the negative pressure box. The cleaning component includes a base, with an ultrasonic cleaner installed on one side of the top surface of the base. The outer wall of the ultrasonic cleaner is fixedly connected to the outer wall of the pair of hydraulic rods.
[0008] Furthermore, linear motors are installed on both the front and back of the base. Each of the two linear motors has a column mounted on its moving end. Each column has a square groove inside. A screw is rotatably connected inside one of the square grooves, and a sliding rod is installed inside the other square groove. A first square plate is threaded onto the outside of the screw, and a second square plate is slidably connected to the outside of the sliding rod. The outer walls of both the first and second square plates are clearance-fitted with the inner wall of the square groove. A first motor is installed at the upper end of one of the columns, and the output end of the first motor is connected to the screw via a transmission connection.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the opposite ends of the first square plate and the second square plate are respectively fixed to the two connecting seats. By setting a linear motor, when the linear motor is started, it is convenient to drive the entire placement assembly to move horizontally in a straight line under the action of the two columns, the first square plate and the second square plate, so that the placement assembly at the ultrasonic cleaner can be moved to the rinsing box. Since the screw is threadedly connected to the first square plate and the slide rod is slidably connected to the second square plate, by setting a first motor, when the first motor is started, it is convenient to drive the screw to rotate, thereby realizing the vertical movement of the entire placement assembly in a straight line and adjusting the height of the placement assembly. When the placement assembly moves downward at the ultrasonic cleaner, it is convenient to perform preliminary fine cleaning. When the placement assembly is at the rinsing box, it moves upward to avoid the inconvenience of flipping it over at the rinsing box later.
[0010] Furthermore, the placement assembly includes two connecting seats, the opposite sides of the two connecting seats are fixedly connected to the first square plate and the second square plate respectively, and the interior of the two connecting seats near the bottom is rotatably connected to the first rotating shaft and the second rotating shaft respectively, and the placement seat is rotatably connected between the first rotating shaft and the second rotating shaft.
[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting a placement seat, it is convenient to place the stamping die holder to be cleaned on the placement seat, and the bottom end of the placement seat is hollow.
[0012] Furthermore, one of the connecting seats has an internal mounting cavity, and a second motor is mounted on the inner wall of the mounting cavity. The output end of the second motor and the outside of the second rotating shaft are both fitted with synchronous pulleys, and a synchronous belt is wound between a pair of synchronous pulleys.
[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting a second motor, when the second motor is started, it is convenient to realize the rotation of the second shaft under the action of the synchronous pulley and the synchronous belt, thereby making the placement seat rotate in the rinsing box, so that the water jet from the high-pressure nozzle can re-rinse the bottom surface of the stamping mold base and the mold cavity.
[0014] Furthermore, each of the four corners of the top surface of the placement base is provided with a limiting plate, and each of the four limiting plates is provided with a first threaded hole. Each of the four corners of the upper end of the placement base is provided with a second threaded hole, and bolts are threadedly connected between adjacent first threaded holes and second threaded holes.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the stamping die holder is placed on the placement seat, at which time the outer wall of the four corners of the stamping die holder is clearance-fitted with the inner wall of the four corners of the placement seat. Then, the limiting plate is placed on the placement seat, and the limiting plate and the placement seat are fixed by bolts to limit the stamping die holder and prevent the stamping die holder from separating from the placement seat during the flipping process.
[0016] Furthermore, the rinsing assembly includes a rinsing tank, which is located on the side of the ultrasonic cleaner away from the hydraulic rod. The bottom end of the rinsing tank is fixedly connected to the upper end of the base. A high-pressure nozzle is installed at the bottom inside the rinsing tank, and a high-pressure pump is installed on the outer wall of the rinsing tank. A high-pressure water pipe is connected between the water outlet of the high-pressure pump and the high-pressure nozzle.
[0017] The beneficial effect of adopting the above-mentioned further solution is that by using a high-pressure pump, a high-pressure water pipe and a high-pressure nozzle in combination, the external water pipe is connected to the water inlet of the high-pressure pump, and then the high-pressure pump is started, so that water can be pumped into the high-pressure nozzle through the high-pressure water pipe and then sprayed out by the high-pressure nozzle to rinse the bottom surface, mold cavity and both sides of the stamping mold base.
[0018] Furthermore, both the rinsing tank and the ultrasonic cleaner have drain pipes connected to their backs, and each of the two drain pipes has a solenoid valve installed at one end.
[0019] The beneficial effect of adopting the above-mentioned further solution is that by connecting the drain pipe to the back of the rinsing tank and the ultrasonic cleaner, the cleaning solution in the ultrasonic cleaner and the water in the rinsing tank can be discharged through the drain pipe after the solenoid valve is opened.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: When the diffuser is side-punched, debris may remain in the die cavity and inner wall of the die holder after the die is side-punched. Before cleaning, the debris in the die cavity of the die holder needs to be cleaned. The die holder is then placed on the placement seat, with the outer walls of the four corners of the die holder and the inner walls of the four corners of the placement seat fitted with a clearance. Then, the limiting plate is placed on the placement seat, and bolts are used to fix the limiting plate to the placement seat, thus limiting the die holder. Then, the hydraulic rod is activated, causing the mounting plate to move downwards, causing the adsorption cylinder to be halfway up. Located inside the mold cavity, several adsorption ports on the adsorption cylinder are aligned with the mold holes on the inner wall of the mold cavity. At this time, the negative pressure fan is activated, creating a negative pressure inside the negative pressure box. Under the action of the adsorption ports, adsorption cylinder, and connecting pipe, the mold holes and residual debris in the mold cavity are forced into the negative pressure box to complete the debris cleaning operation. By installing filter screens on both sides inside the negative pressure fan, debris is prevented from directly entering the negative pressure fan and causing damage. The box door is hinged at the back of the negative pressure box for easy opening and cleaning of debris inside the negative pressure box. An ultrasonic cleaner filled with cleaning solution is installed to perform preliminary fine cleaning of the stamping mold base. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-5 This utility model provides a technical solution: Limiting plates 2006 are provided at the four corners of the top surface of the placement base 2005. Each of the four limiting plates 2006 has a first threaded hole inside. Second threaded holes are provided at the four corners of the upper end of the placement base 2005. Bolts are threadedly connected between adjacent first and second threaded holes. The rinsing assembly 400 includes a rinsing tank 4001, which is located on the side of the ultrasonic cleaner 1002 away from the hydraulic rod 3001. The bottom end of the rinsing tank 4001 is fixedly connected to the upper end of the base 1001. A high-pressure nozzle 4003 is installed at the bottom inside the rinsing tank 4001, and a high-pressure pump 4002 is installed on the outer wall of the rinsing tank 4001. A high-pressure water pipe connects the outlet end of the high-pressure pump 4002 to the high-pressure nozzle 4003. Both the back of the 1 and the ultrasonic cleaner 1002 are connected to drain pipes, and a solenoid valve is installed at one end of each drain pipe. The lower die base is placed on the placement seat 2005. At this time, the outer wall of the four corners of the lower die base is fitted with the inner wall of the four corners of the placement seat 2005 with clearance. Then, the limiting plate 2006 is placed on the placement seat 2005, and the limiting plate 2006 is fixed to the placement seat 2005 with bolts to limit the lower die base and prevent the lower die base from separating from the placement seat 2005 during the flipping process. The external water pipe is connected to the water inlet of the high pressure pump 4002, and then the high pressure pump 4002 is started to facilitate the pumping of water through the high pressure water pipe into the high pressure nozzle 4003, and then sprayed out by the high pressure nozzle 4003 to rinse the bottom surface, mold cavity and sides of the lower die base.
[0033] Specifically, the working principle of this mold cleaning device is as follows: During use, after side punching of the diffuser, debris may remain in the mold cavity and inner wall of the lower die holder. Before cleaning, the debris in the mold cavity of the lower die holder needs to be cleaned. The lower die holder is placed on the placement seat 2005, with a clearance fit between the outer walls of the four corners of the lower die holder and the inner walls of the four corners of the placement seat 2005. Then, the limiting plate 2006 is placed on the placement seat 2005, and bolts are used to fix the limiting plate 2006 to the placement seat 2005, thus limiting the lower die holder. The hydraulic system is then activated. Rod 3001 causes mounting plate 3002 to move downwards, resulting in half of adsorption cylinder 3003 being located inside the mold cavity. Simultaneously, several adsorption ports 3004 on adsorption cylinder 3003 align with the mold holes on the inner wall of the mold cavity. At this point, negative pressure fan 3007 is activated, creating negative pressure within negative pressure box 3005. Under the action of adsorption ports 3004, adsorption cylinder 3003, and connecting pipe 3006, residual debris from the mold holes and mold cavity is forced into negative pressure box 3005, completing the debris cleaning operation. Filter screens are installed on both sides of the inside of negative pressure fan 3007 to prevent debris from directly entering and damaging it. Then, when the first motor 1008 is started to drive the screw 1006 to rotate, the height of the placement component 200 is adjusted. When the placement component 200 moves downward at the ultrasonic cleaner 1002, the placement seat 2005 and the stamping die seat are immersed in the cleaning solution inside the ultrasonic cleaner 1002. The ultrasonic cleaner 1002 is then started for preliminary fine cleaning. Afterward, the linear motor 1003 is started, which, under the action of the two columns 1004, the first square plate, and the second square plate 1005, drives the entire placement component 200 to move horizontally in a straight line, so that the placement component 200 at the ultrasonic cleaner 1002 moves to the rinsing tank. At position 4001, the first motor 1008 moves the placement component 200 upward to prevent it from flipping over in the rinsing tank 4001 later. When the second motor 2003 is started, the second shaft rotates under the action of the synchronous pulley 2004 and the synchronous belt, which in turn makes the placement seat 2005 rotate in the rinsing tank 4001. The high-pressure pump 4002 is started to pump water through the high-pressure water pipe into the high-pressure nozzle 4003, and then spray it out from the high-pressure nozzle 4003 to rinse the bottom surface, cavity and sides of the lower stamping mold base again, so as to prevent the chemical components in the cleaning solution from remaining on the metal surface of the lower stamping mold base.
