Description

Technical Field

[0001] This utility model relates to the field of tooling technology for injection molding of automotive stabilizer bars, specifically to a clamping tooling for injection molding the central ring structure of an automotive stabilizer bar. Background Technology

[0002] Automotive stabilizer bars are high-strength cast iron parts in automobiles. Depending on the vehicle model, both ends need to be bent into specific shapes. At the junction of the bend and the straight line, a ring sleeve is often needed to facilitate stable installation on the vehicle. This ring sleeve often needs to be die-cast onto the automotive stabilizer bar, which requires the use of specialized clamping fixtures. The arc groove on the clamping fixture can often meet the die-casting operation of most common automotive stabilizer bars. However, the base of traditional clamping fixtures is fixed, and the input and output directions of the workpiece during the die-casting operation are also fixed, which cannot meet the needs of flexible switching between production workshops in modern times.

[0003] The existing clamping fixtures specifically used for die casting of automotive stabilizer bar ring sleeves have fixed input and output directions, resulting in a narrow range of applications. For example, the die casting machine tooling fixture for brake housings disclosed in CN214557282U includes a worktable, on which a clamping device is fixedly mounted. A bottom mold is provided on the top of the worktable, and the bottom of the bottom mold contacts the top of the worktable. A mounting bracket is fixedly connected to the top of the worktable, and an electric push rod is fixedly mounted on the top of the mounting bracket. This utility model allows for quick assembly and disassembly of the die-casting machine's bottom mold when it needs to be replaced or repaired. The operator controls the separation of the clamping device from the bottom mold, enabling its removal. This facilitates rapid assembly and disassembly of the bottom mold. The top mold is then installed inside the positioning device, and an electric push rod moves the positioning device and top mold downwards simultaneously until they contact the bottom mold. Subsequently, the brake housing can be die-cast. This solves the problem that previous die-casting machine fixtures could not quickly assemble and disassemble the mold for brake housings. However, this solution uses a fixed die-casting material and direction, which cannot meet the requirement of conveying workpieces in multiple directions.

[0004] Therefore, it is necessary to invent a clamping fixture for injection molding the central ring structure of a car stabilizer bar to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a clamping fixture for injection molding the central ring structure of an automotive stabilizer bar, thereby solving the problem that existing fixtures for injection molding the ring structure of automotive stabilizers have limited functionality, only satisfying conveying and operation in one direction and lacking overall functionality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamping fixture for injection molding a central ring structure of an automotive stabilizer bar includes a feeding mechanism, an extrusion mechanism, a hot-melt mechanism, a spare hydraulic cylinder, and a clamping mechanism. The feeding mechanism is connected to a heating chamber at the bottom of the hot-melt mechanism via a pipe. The heating chamber at the bottom of the hot-melt mechanism is directly connected to an upper clamping seat within the clamping mechanism. An extrusion mechanism is installed at the bottom of the feeding mechanism. The bottom of the extrusion mechanism is connected to the hot-melt mechanism and the spare hydraulic cylinder, which provides a backup drive source for the extrusion mechanism. The clamping mechanism contains multiple telescopic rods and an upper clamping seat and a lower clamping seat. The upper and lower clamping seats are positioned opposite each other. An arc-shaped groove is formed on the lower clamping seat, and multiple contact rods of the same height are arranged in the arc-shaped groove to fix the central part of the automotive stabilizer bar. The multiple contact rods are distributed symmetrically about the extrusion groove, and an extrusion groove is also formed at the corresponding position of the upper clamping seat. A through hole for extruding material is provided in the extrusion groove of the upper clamping seat.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] This invention uses upper and lower clamping seats within a clamping mechanism to hold the vehicle stabilizer bar between them. Simultaneously, an extrusion groove is used to install extruded injection-molded material onto the stabilizer bar. Rubber rods, springs, and damping mechanisms buffer the force exerted during the closing and pressing of the upper and lower clamping seats, extending the service life of the lower clamping seat. Rotating components installed on both the upper and lower clamping seats allow for rotation, meeting the processing needs of stabilizer bars transported from multiple directions. Furthermore, the operation of rotating and fixing the upper and lower clamping seats is simple, efficient, and the entire clamping fixture is highly functional. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown, a clamping fixture for injection molding the central ring structure of a car stabilizer bar includes a feeding mechanism 1, an extrusion mechanism 2, a hot melt mechanism 3, a spare hydraulic cylinder 4, and a clamping mechanism 5. The feeding mechanism 1 is connected to the heating chamber at the bottom of the hot melt mechanism 3 via a pipe. The heating chamber at the bottom of the hot melt mechanism 3 is directly connected to the upper clamping seat 7 inside the clamping mechanism 5. The extrusion mechanism 2 is installed at the bottom of the feeding mechanism 1. The bottom of the extrusion mechanism 2 is connected to the hot melt mechanism 3 and the spare hydraulic cylinder 4. The spare hydraulic cylinder 4 provides a backup drive source for the extrusion mechanism 2. The clamping mechanism 5 is equipped with multiple telescopic rods 6 and an upper clamping seat 7. The lower clamp seat 8 and the upper clamp seat 7 are positioned opposite each other. The lower clamp seat 8 has an arc-shaped groove, and multiple contact rods 805 of the same height are arranged in the arc-shaped groove to fix the middle part of the vehicle stabilizer bar. The multiple contact rods 805 are distributed symmetrically about the extrusion groove 806, and the corresponding position of the upper clamp seat 7 also has an extrusion groove 806. The extrusion groove 806 of the upper clamp seat 7 is provided with a through hole for extruding material. The clamping mechanism 5 is used to extend the middle part of the vehicle stabilizer bar and extrude injection molding material at the extrusion groove 806. The injection molding material wraps around the middle part of the vehicle stabilizer bar.

[0018] The entire clamping fixture can accommodate injection molded parts transported from production lines in different directions. It can rotate the upper clamping seat 7 and the lower clamping seat 8 by 90 degrees to meet the installation operation of injection molded parts from different production line directions. The entire clamping fixture is highly adaptable.

[0019] The clamping mechanism 5 is rotatably connected to a rotating component 801 at its bottom. A pin 802 is provided through the rotating component 801. A limiting insertion hole 9 is provided on the clamping mechanism 5, which is adapted to the diameter of the pin 802. The lower clamp seat 8 includes a lower split seat 807 and an upper split seat 808 installed on the rotating component 801. The lower split seat 807 and the upper split seat 808 can slide relative to each other. The side formed by the lower split seat 807 and the upper split seat 808 has a cavity. Multiple rubber rods 803 and springs 804 are installed in the cavity and distributed between the lower split seat 807 and the upper split seat 808. The springs 804 are provided with damping rods to buffer the squeezing force on the lower clamp seat 8.

[0020] When the upper clamp seat 7 moves downward until it is in contact with the surface of the lower clamp seat 8, the lower clamp seat 8 is subjected to a large compressive force. This compressive force is partially released by multiple rubber rods 803 and springs 804 through elastic potential energy, which can reduce the impact and wear on the lower clamp seat 8 and extend the service life of the lower clamp seat 8.

[0021] The top of the upper clamping seat 7 is also provided with a component with the same shape as the rotating part 801 for rotational connection, and a threaded rod 701 is also provided through it. The top of the clamping mechanism 5 is provided with a threaded hole with a diameter that matches the threaded rod 701. There are four limiting holes 9. The rotating part 801 rotates 90 degrees at one time. The limiting holes 9 are interference-fitted with the pin 802. The top of the upper clamping seat 7 is also provided with four threaded holes, which are threadedly engaged with the threaded rod 701.

[0022] The lower clamp seat 8 can rotate 90 degrees at a time by rotating the rotating member 801, and can be inserted into the matching limit socket 9. The upper clamp seat 7 can also rotate 90 degrees at a time to match the lower clamp seat 8.

[0023] During operation, the middle part of the car stabilizer bar to be installed is first placed on multiple contact rods 805, and its position is defined by the multiple contact rods 805. The extrusion mechanism 2 is activated to drive the entire clamping mechanism 5 downward to extrude until the upper clamp seat 7 and the lower clamp seat 8 are completely in contact. At the same time, the injection material in the feeding mechanism 1 is conveyed from the hot melt mechanism 3 to the extrusion groove 806 in the upper clamp seat 7. The material is firmly formed in the extrusion groove 806. The force during the extrusion process is consumed by multiple springs 804, damping and rubber rods 803, reducing the impact force on the lower clamp seat 8 and extending the service life of the lower clamp seat 8.

[0024] After the upper clamp seat 7 and the lower clamp seat 8 are released, the upper clamp seat 7 returns to its original position, and the car stabilizer bar that has been fitted with the injection molded part will be released within the range of multiple contact rods 805 and can be removed. When the conveying direction of the car stabilizer bar on the production line is different, the lower clamp seat 8 can be rotated at a right angle and fixed in position using the pin 802 and the limiting hole 9. At the same time, the upper clamp seat 7 should also be rotated so that the positions of the arc grooves of the upper clamp seat 7 and the lower clamp seat 8 correspond, so that the extrusion groove 806 can be completely closed.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
