Description

Technical Field

[0001] This utility model relates to the field of auxiliary forming device for the production of irregular-shaped sealing rings, and in particular to an auxiliary forming device for the production of irregular-shaped sealing rings. Background Technology

[0002] U-shaped seals are a type of seal used at the piston ring position. Most of them are made of rubber or PU materials. The production of these materials requires casting with corresponding molds and then pressing to form the seal.

[0003] In Chinese utility model patents, such as CN220314035U, this utility model relates to a U-shaped sealing ring forming device. This utility model optimizes the setting of the U-shaped sealing ring forming device, changes the traditional casting structure, and designs a design to reduce the impact of internal pressure problems. The structure adopts a three-layer clamping design, and the forming structure adopts a secondary pressure casting method, which reduces the drawbacks of its stability after production. In addition, the structure adopts a fully disassembled parts design, which makes it more convenient and simple to use and maintain, and is suitable for widespread use.

[0004] However, when using the above technology, after the raw materials have cooled in the molding tank, each sealing ring needs to be removed manually, and the surface of the sealing ring is easily damaged during the removal process. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art by proposing an auxiliary forming device for the production of irregular-shaped sealing rings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary molding device for producing irregularly shaped sealing rings includes a base, with rotating seats rotatably connected to both ends of the base via rotating shafts. A molding plate is slidably connected inside the rotating seats, and a spring is provided inside the rotating seats, with one end of the molding plate connected to the spring. A motor is fixedly installed at one end of the base, and the output shaft of one of the rotating shafts is connected to the motor. Two vibration boxes are symmetrically fixedly installed on the side of the rotating seats. Each vibration box has a drive mechanism connected to one of the rotating shafts. Each vibration box has a vibrating plate, and the drive mechanism drives the vibrating plate to reciprocate. Two through slots are symmetrically opened inside the rotating seats, and each through slot corresponds to the vibrating plate.

[0008] Preferably, the driving mechanism includes a reciprocating screw, which is rotatably connected to a vibration box at a corresponding position. A screw sleeve is threaded onto the reciprocating screw, and multiple connecting shafts are fixedly installed on the side of the screw sleeve. The other end of each connecting shaft is fixedly installed on the side of a vibration plate at a corresponding position.

[0009] Preferably, each of the vibration boxes has a cavity, and the cavity is square in shape, and the side of each lead screw sleeve is slidably connected to the inner wall of the cavity at the corresponding position.

[0010] Preferably, a baffle is fixedly installed at one end of each reciprocating screw, and the diameter of the baffle is greater than the diameter of the reciprocating screw.

[0011] Preferably, a drive gear is mounted on one of the rotating shafts, and a driven gear is mounted on one end of each of the reciprocating screws, and each driven gear meshes with the drive gear.

[0012] Preferably, the pitch circle diameter of each driven gear is smaller than the pitch circle diameter of the driving gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves the synchronous rotation of the rotating seat and the plastic plate by setting up a motor, rotating shaft and other devices. Then, the formed sealing ring can be separated by its own gravity, without the need for workers to use tools to pry up the sealing ring, thus avoiding damage to the sealing ring.

[0015] 2. This utility model achieves reciprocating vibration of the molding plate by setting up a reciprocating screw, a vibrating plate, a spring, etc., which avoids the irregular sealing ring from sticking to the molding plate during the cooling process because the groove cross section of the sealing ring is not rectangular or circular. The rapid reciprocating vibration can accelerate the detachment of the irregular sealing ring.

[0016] In summary, this utility model is simple to operate. It can detach the formed sealing ring by its own weight, and at the same time, it can vibrate the plastic plate through the vibrating plate to accelerate the detachment of the irregular sealing ring. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 An auxiliary molding device for producing irregular sealing rings includes a base 1. Both ends of the base 1 are rotatably connected to a rotating seat 2 via a rotating shaft 4. A plastic molded plate 3 is slidably connected inside the rotating seat 2. A spring 7 is provided inside the rotating seat 2, and one end of the plastic molded plate 3 is connected to the spring 7. A motor 5 is fixedly installed at one end of the base 1, and the output shaft of one of the rotating shafts 4 is connected to the motor 5. Two vibration boxes 6 are symmetrically fixedly installed on the side of the rotating seat 2.

[0023] Furthermore, each vibration box 6 is equipped with a drive mechanism, and the drive mechanism is connected to one of the rotating shafts 4. A drive gear 9 is installed on one of the rotating shafts 4. A driven gear 10 is installed at one end of each reciprocating screw 11, and each driven gear 10 meshes with the drive gear 9. By starting the motor 5, the rotating shaft 4 is driven to rotate, and then the driven gear 10 is driven to rotate through the drive gear 9, thereby driving the drive mechanism to operate.

[0024] It should be noted that the pitch circle diameter of each driven gear 10 is smaller than that of the drive gear 9, thereby increasing the transmission ratio and accelerating the operation speed of the drive mechanism.

[0025] Furthermore, the drive mechanism includes a reciprocating screw 11, which is rotatably connected to the vibrating box 6 in the corresponding position. A screw sleeve 12 is threaded onto the reciprocating screw 11. Multiple connecting shafts 13 are fixedly installed on the side of the screw sleeve 12, and the other end of each connecting shaft 13 is fixedly installed on the side of the vibrating plate 14 in the corresponding position. The reciprocating screw 11 is driven to rotate by the driven gear 10, and the vibrating plate 14 is driven to perform reciprocating linear motion by the multiple connecting shafts 13 installed on the screw sleeve 12.

[0026] It should be noted that each vibration box 6 has a cavity, and the cavity is square in shape. The side of each lead screw sleeve 12 is slidably connected to the inner wall of the cavity at the corresponding position. Thus, the cavity limits the lead screw sleeve 12, so that it can only move linearly and cannot rotate.

[0027] It should be noted that a baffle 15 is fixedly installed at one end of each reciprocating screw 11, and the diameter of the baffle 15 is greater than the diameter of the reciprocating screw 11. Thus, the baffle 15 limits the screw sleeve 12, preventing it from disengaging from the reciprocating screw 11.

[0028] Furthermore, each vibration box 6 is equipped with a vibration plate 14, and the driving mechanism drives the vibration plate 14 to reciprocate. Two through slots 8 are symmetrically opened in the rotating seat 2, and each through slot 8 corresponds to the vibration plate 14. The vibration plate 14 passes through the through slot 8 to abut against the molding plate 3. The reciprocating vibration of the molding plate 3 is achieved through the process of the vibration plate 14 abutting against and separating from the molding plate 3, and the molding plate 3 is reset by the spring 7.

[0029] When this utility model is in use, the motor 5 is started, which drives one of the rotating shafts 4 to rotate, which in turn drives the rotating seat 2 to rotate, so that the plastic plate 3 inside the rotating seat 2 rotates synchronously. Then, the formed sealing ring can be naturally detached by its own gravity, without the need for workers to use tools to pry up the sealing ring, thus avoiding damage to the sealing ring.

[0030] Simultaneously, during the rotation of the rotating seat 2, the drive gear 9 meshes with the driven gear 10, thereby driving the reciprocating screw 11 to rotate. During the rotation, the screw sleeve 12 is threadedly connected to the reciprocating screw 11, causing the screw sleeve 12 to reciprocate. Through multiple connecting shafts 13, the vibrating plate 14 is pushed through the through groove 8 and comes into contact with the molding plate 3, achieving repeated contact between the vibrating plate 14 and the molding plate 3. During the process of the vibrating plate 14 separating from the molding plate 3, the spring 7 resets the molding plate 3, thereby achieving reciprocating vibration of the molding plate 3. Due to the irregularly shaped sealing ring, during the cooling process, since the groove cross-section of the sealing ring is not rectangular or circular, the sealing ring will stick to the molding plate 3. Rapid reciprocating vibration can accelerate the separation of the irregularly shaped sealing ring.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
