Description

Technical Field

[0001] This invention relates to the field of plastic frame technology, specifically to a plastic frame molding device for automotive stabilizer bars. Background Technology

[0002] A stabilizer bar, also known as a car stabilizer bar, is a lateral device installed between the vehicle frame and the control arms. It is part of the car's suspension system. Sometimes it is also called an anti-roll bar or anti-hitch bar. Its function is to reduce the movement of the suspension system and the sway of the vehicle body. Especially when a car is cornering, the centrifugal force causes the car body to tilt, and the stabilizer bar's counteracting torque is sufficient to reduce the degree of outward deviation of the car.

[0003] Stabilizer bars are typically protected with protective sleeves during use. These sleeves consist of an inner sleeve and an outer sleeve. The inner sleeve prevents corrosion and wear on the stabilizer bar, while the outer sleeve withstands friction and impacts from the outside environment. Both the inner and outer sleeves are composed of two semi-circular sleeves, which protect the bar by being installed on its outer wall. In special environments, such as high temperature, cold, humidity, or corrosive conditions, a plastic frame is installed between the inner and outer sleeves to support the entire structure. This plastic frame also consists of two semi-circular plastic skeletons to enhance its stability and strength. The plastic frame is formed using a molding device.

[0004] The existing molding equipment forms the plastic skeleton. Since the newly formed skeleton is relatively stable, workers may risk burns if they take it out directly. Therefore, they need to wait for a certain period of time before taking it out, which affects efficiency. In addition, the newly formed plastic may have some burrs on both sides, which will affect its use. Workers need to use a hand-held grinder to polish it, which increases the workload of the workers.

[0005] Therefore, this invention designs a plastic frame molding device for automotive stabilizer bars to solve the problems existing in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a plastic frame molding device for automotive stabilizer bars to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a plastic frame molding device for automotive stabilizer bars, comprising: a machine base, a hydraulic cylinder mounted on one side of the top of the machine base, an upper mold connected to the output end of the hydraulic cylinder, a lower mold fixedly mounted to the inner wall of the bottom of the machine base directly below the upper mold, a transverse moving assembly at one end of the machine base, an adsorption assembly one and an adsorption assembly two mounted on the transverse moving assembly, a grinding machine mounted on the side of the machine base away from the lower mold, an adjusting assembly at the top of the machine base, a cleaning assembly below the grinding machine, and an air pump mounted on the transverse moving assembly.

[0008] Preferably, the transverse moving component includes a transverse groove, which is formed on the inner wall of the machine base near the lower mold. A transverse moving screw is provided in the transverse groove and is rotatably mounted with the machine base. A transverse moving plate is slidably mounted on the outer wall of the transverse moving screw via threads. The first adsorption component and the second adsorption component are respectively arranged at the bottom ends of the transverse moving plate.

[0009] Preferably, the transverse groove is provided with a guide rod that is slidably connected to the transverse plate, and both the upper and lower ends of the transverse plate are provided with rollers that are slidably connected to the machine platform. The guide rod guides the transverse plate, and the movement of the transverse plate drives the rollers to roll with the machine platform, which can reduce friction.

[0010] Preferably, the adsorption assembly includes a bottom groove located at one bottom end of the transverse plate. An adsorption screw, rotatably mounted to the transverse plate, is disposed within the bottom groove. A slider is slidably mounted on the outer wall of the adsorption screw via threads. An adsorption electric cylinder is mounted at the bottom of the slider. An arc-shaped box is mounted at the bottom of the adsorption electric cylinder. Several suction nozzles are located at the bottom of the arc-shaped box. The arc-shaped box is connected to a vacuum pump via a flexible hose. When the arc-shaped box moves to the top of the frame, the adsorption electric cylinder lowers the arc-shaped box, allowing the suction nozzles to adsorb onto the top of the frame, facilitating grinding of the bottom of the frame by the grinding machine.

[0011] Preferably, the second adsorption component includes a second bottom groove, which is located at the bottom of the other end of the transverse plate. An adsorption screw second, rotatably mounted to the transverse plate, is disposed within the second bottom groove. A slider second is slidably mounted on the outer wall of the second adsorption screw via threads. An adsorption electric cylinder second is mounted at the bottom of the slider second. The output end of the adsorption electric cylinder second is connected to one end of a hollow arc-shaped plate via a connecting frame. Several suction nozzles second are provided on the top of the hollow arc-shaped plate. The hollow arc-shaped plate is connected to a vacuum pump via a flexible hose. When the hollow arc-shaped plate moves to the bottom of the frame, the adsorption electric cylinder second drives the hollow arc-shaped plate upward, allowing the suction nozzles second to adsorb the bottom of the frame. Then, the first adsorption component separates from the frame, exposing the top of the frame for easy grinding by the grinding machine.

[0012] Preferably, the adjusting component includes a top groove, which is located on the inner wall of the top of the machine base away from the upper mold. A screw rod rotatably mounted within the top groove is provided. A screw block is slidably mounted on the outer wall of the screw rod via threads. An electric push rod is mounted at the bottom of the screw block. An electric push rod 1 is connected to an electric push rod 2 at its output end. The output end of the electric push rod 2 is connected to a frame. An adjusting motor is installed within the frame. The output end of the adjusting motor is connected to one end of a U-shaped frame. A rotating block is rotatably mounted between the two sides of the U-shaped frame via a pin. The bottom of the rotating block is connected to the top of the grinding machine. The rotating block drives the grinding machine to rotate, allowing adjustment of the grinding machine angle for convenient grinding of the curved surface of the frame. By adjusting the motor to drive the U-shaped frame to rotate, the grinding machine can be adjusted upwards or downwards for convenient grinding of both sides of the frame.

[0013] Preferably, the cleaning component includes a through groove located on the lower side of the inner wall of one end of the machine base away from the lower mold. A cleaning screw, rotating and mounted with the machine base, is installed within the through groove. A slider is slidably mounted on the outer wall of the cleaning screw via threads. One end of the slider has a mounting groove containing a cleaning motor. The output end of the cleaning motor is connected to a brush plate. A magnetic plate is mounted on one side of the machine base, and a metal collection box is placed on top of the magnetic plate. After the cleaning screw moves the slider to the side of the lower mold, the cleaning motor rotates the brush plate downwards by 90 degrees. Then, the cleaning screw moves the slider towards the metal collection box, thus collecting debris. The magnetic plate can attract the metal collection box, improving its stability.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention, through the setting of a transverse component and an adsorption component, allows the transverse screw to move the transverse plate above the lower mold, and then the adsorption electric cylinder to lower the arc-shaped box so that the suction nozzle adsorbs the plastic frame. Then the adsorption electric cylinder retracts, which can drive the plastic frame to rise and leave the lower mold. Then the transverse screw drives the transverse plate to move, which can make the frame leave the top of the lower mold, thus completing the unloading of the plastic frame. There is no need to wait for the plastic frame to cool down, which improves the unloading efficiency and avoids burns to the workers.

[0016] 2. By adjusting the mechanism and the second adsorption component, the bottom of the frame can be ground by first pointing the grinder upwards. The angle of the grinder can be adjusted to facilitate grinding different parts of the curved surface. After the bottom is ground, the second adsorption component adsorbs the bottom of the frame. Then the first adsorption component moves away from the top of the frame, and the grinder points downwards to grind and remove burrs from the top of the frame. This eliminates the need for workers to hold the grinder while grinding, reducing the workload of workers.

[0017] 3. The present invention, through the setting of the cleaning component, the cleaning screw drives the slider to move the brush plate to the side close to the lower mold, and then the cleaning motor drives the brush plate to rotate 90 degrees to make the brush plate contact the machine. Then the slider drives the brush plate to move towards the metal collection box. The brush plate can then carry the grinding debris into the metal collection box, eliminating the need for manual cleaning by the staff and further reducing the workload of the staff.

[0034] Working principle: Hydraulic cylinder 2 drives the upper mold 3 to descend and contact the lower mold 4 to form the skeleton. Then, the upper mold 3 rises, and the transverse screw 502 drives the transverse plate 503 to move above the lower mold 4. The suction electric cylinder 604 drives the arc box 605 to descend, so that the suction nozzle 606 can pick up the skeleton. The suction electric cylinder 604 then drives the fixed part to rise. Then, the transverse plate 503 returns to its original position, causing the skeleton to leave the upper part of the lower mold 4, thus completing the automatic unloading. The adjusting motor 907 drives the U-shaped frame 908 to rotate, so that the grinding machine 8 faces upward. Then, the electric push rod 904 drives the electric push rod 905 to descend. Electric push rod 905 then extends the grinder 8, moving it to the bottom of the frame. Electric push rod 904 then raises the grinder 8 to contact the bottom of the frame. Screw 902 moves screw block 903, deburring the bottom of the frame. The angle of the grinder 8 can be adjusted by rotating block 909, facilitating deburring at different locations on the frame's curved surface. After deburring the bottom, the grinder 8 moves away from the frame. Adsorption screw 702 moves slider 703, moving the hollow curved plate 706 to the bottom of the frame. Then, adsorption electric cylinder 704... The hollow arc-shaped plate 706 rises, causing the suction nozzle 707 to adhere to the bottom of the skeleton. Then, the suction nozzle 606 releases its grip on the skeleton, and the suction screw 602 moves the arc-shaped box 605 closer to the suction electric cylinder 704, moving the arc-shaped box 605 away from the top of the skeleton. Then, the motor 907 rotates the U-shaped frame 908, causing the grinder 8 to face downwards. The electric push rod 905 moves the grinder 8 to the top of the skeleton, and then the electric push rod 904 lowers the grinder 8, deburring the top of the grinder 8. After deburring both the top and bottom, the skeleton can be removed. The frame is deburred for easier subsequent use. When debris accumulates on the inner wall of the bottom of the machine 1, the cleaning screw 102 can be rotated to move the slider 103 and the brush plate 106 to the side of the mold 4. Then, the cleaning motor 105 drives the brush plate 106 to rotate 90 degrees so that the brush plate 106 faces downward and contacts the machine 1. Then, the cleaning screw 102 reverses and drives the brush plate 106 to move towards the metal collection box 108, thus sweeping the debris to the metal collection box 108. Through automatic cleaning, the workload of the workers is reduced. The contents not described in detail in the description are existing technologies known to those skilled in the art.
