Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a steering gear housing mold. Background Technology

[0002] The function of the steering gear is to appropriately transform the steering torque and steering angle from the steering wheel and then output them to the steering tie rod mechanism, thereby turning the car. The steering gear housing is mostly produced using molds, which results in high production efficiency.

[0003] Because the existing steering gear structure is complex, the mold is not convenient for demolding the steering gear housing during use, which can easily affect work efficiency. Therefore, this utility model proposes a steering gear housing mold to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as complex steering gear structure, difficulty in demolding the steering gear housing during use, and easy impact on work efficiency, and to propose a steering gear housing mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steering gear housing mold includes a base, a first electric push rod, a second electric push rod, a third electric push rod, and a bracket. The bracket is fixedly mounted on the top of the base. The first, second, and third electric push rods are respectively fixedly mounted on the left side, rear side, and top of the bracket. The steering gear housing mold also includes...

[0007] The lining mechanism and the demolding mechanism are respectively engaged with the lining mechanism and the base;

[0008] A mold mechanism, comprising: a lower mold and an upper mold;

[0009] The lower mold is fixedly installed on the top of the base, and the upper mold is fixedly installed on the top of the third electric push rod.

[0010] As a preferred embodiment of this utility model, the inner lining mechanism includes: a first inner lining and a second inner lining;

[0011] The left side of the first inner liner is fixedly connected to the output shaft of the first electric push rod, and the second inner liner is fixedly installed on the front side of the output shaft of the second electric push rod. Both the first inner liner and the second inner side are in sliding contact with the inner walls of the upper mold and the lower mold.

[0012] Furthermore, the first inner liner is driven to move left and right by the first electric push rod, and the second inner liner is driven to move back and forth by the second electric push rod. Both can slide in contact with the inner walls of the upper and lower molds. This structure can flexibly adapt to the shape changes of the inner cavity of the steering gear housing, ensuring accurate molding of complex inner cavity structures and solving the problem of high demolding resistance or product damage caused by complex inner cavities.

[0013] As a preferred embodiment of this utility model, the demolding mechanism includes: three ejector rods, a sliding plate, five support rods, a rotating frame, a turntable, and a push rod;

[0014] The top of the ejector rod extends into the lower mold. The ejector rod is fixedly installed on the top of the sliding plate. The support rod is fixedly installed on the top of the base. The top of the support rod slides in contact with the bottom of the sliding plate. The rotating frame is fixedly installed on the top of the base. The turntable is rotatably connected to the front side of the rotating frame. The push rod is rotatably connected to the sliding plate and the turntable respectively.

[0015] Furthermore, three ejector rods are connected to a sliding plate and extend into the lower mold. The support rod provides sliding support for the sliding plate. The rotating turntable drives the sliding plate to move up and down through the push rod, thereby simultaneously driving the three ejector rods to eject the casting. This centralized operation structure utilizes the lever principle to uniformly lift the complex shell with a smaller operating force, effectively overcoming demolding resistance, significantly improving demolding efficiency and success rate, and reducing the risk of product damage.

[0016] As a preferred embodiment of this utility model, the bottom of the lower mold is provided with symmetrically arranged vertical grooves, and the left and right sides of the sliding plate are slidably connected to the inner walls of the two vertical grooves respectively.

[0017] Furthermore, a vertical groove is provided at the bottom of the lower mold for the sliding plate to slide, providing precise guidance for the up and down movement of the sliding plate, ensuring that the ejector rod moves smoothly and vertically, and avoiding damage to the casting due to uneven ejection.

[0018] As a preferred embodiment of this utility model, the bottom of the lower mold is provided with a plurality of circular through holes arranged at equal intervals, and the outer side of the push rod slides in contact with the inner wall of the circular through holes.

[0019] Furthermore, a circular through hole is provided at the bottom of the lower mold for the ejector pin to slide. The through hole provides a tight constraint on the ejector pin, ensuring that the ejector pin's movement trajectory is accurate and the ejection position is accurate and reliable.

[0020] As a preferred embodiment of this utility model, the top of the upper mold has two symmetrically arranged injection ports.

[0021] Furthermore, symmetrical injection ports are opened at the top of the upper mold. The dual-inlet design helps the molten material to fill the complex mold cavity more quickly and evenly, reducing injection defects and improving the quality of the casting.

[0022] As a preferred embodiment of this utility model, a rectangular block is fixedly installed on the inner side of the second inner lining, the rectangular block slides in contact with the first inner lining, a circular through hole is opened on the rectangular block, and a round rod is fixedly installed on the bottom of the upper mold, the bottom of the round rod slides in contact with the inner wall of the circular through hole.

[0023] Furthermore, the second inner liner fixing rectangular block slides in contact with the first inner liner, and the rectangular block has a through hole that slides with the round rod of the upper mold. This structure uses the round rod inserted into the through hole to assist in the precise positioning of the inner liner when the mold is closed, ensuring the accurate position of the inner liner and preventing misalignment from affecting the internal structural accuracy of the casting.

[0024] Beneficial effects:

[0025] 1. The first inner liner is driven to move left and right by the first electric push rod, and the second inner liner is driven to move back and forth by the second electric push rod. Both can slide to contact the inner walls of the upper and lower molds. This structure can flexibly adapt to the shape changes of the inner cavity of the steering gear housing, ensuring accurate molding of complex inner cavity structures and solving the problem of large demolding resistance or product damage caused by complex inner cavities.

[0026] 2. Three ejector rods are connected to a sliding plate and extend into the lower mold. The support rod provides sliding support for the sliding plate. The rotating turntable drives the sliding plate to move up and down through the push rod, thereby simultaneously driving the three ejector rods to eject the casting. This centralized operation structure utilizes the lever principle to uniformly lift the complex shell with a smaller operating force, effectively overcoming demolding resistance, significantly improving demolding efficiency and success rate, and reducing the risk of product damage.

[0027] In this utility model: by setting an inner lining mechanism and a demolding mechanism in conjunction with a mold mechanism, the inner lining mechanism is used to form the internal structure of the complex shell, and the demolding mechanism is specifically designed to solve the problem of difficult demolding. The third electric push rod drives the upper mold to open and close, the first and second electric push rods drive the inner lining mechanism to move, and the lower mold is fixed to the base.

The steering gear housing mold also includes...

[0036] The inner lining mechanism and the demolding mechanism are respectively matched with the inner lining mechanism and the base 1;

[0037] The mold mechanism includes: lower mold 2 and upper mold 7;

[0038] The lower mold 2 is fixedly installed on the top of the base 1, and the upper mold 7 is fixedly installed on the top of the third electric push rod 8.

[0039] With the above structure: by setting an inner lining mechanism and a demolding mechanism in conjunction with the mold mechanism, the inner lining mechanism is used to form the complex internal structure of the shell, and the demolding mechanism is specifically designed to solve the problem of demolding difficulty. The third electric push rod 8 drives the upper mold 7 to open and close, the first and second electric push rods 5 drive the inner lining mechanism to move, and the lower mold 2 is fixed to the base 1. The overall structure is designed for the complex shape of the steering gear shell, which improves the molding accuracy and demolding convenience.

[0040] To achieve the molding of the steering gear housing, the inner lining mechanism includes: a first inner lining 4 and a second inner lining 6;

[0041] The left side of the first inner liner 4 is fixedly connected to the output shaft of the first electric push rod 3, and the second inner liner 6 is fixedly installed on the front side of the output shaft of the second electric push rod 5. The first inner liner 4 and the second inner side are both in sliding contact with the inner walls of the upper mold 7 and the lower mold 2. The first inner liner 4 is driven to move left and right by the first electric push rod 3, and the second inner liner 6 is driven to move back and forth by the second electric push rod 5. Both can slide in contact with the inner walls of the upper and lower molds 2. This structure can flexibly adapt to the shape changes of the inner cavity of the steering gear housing, ensure accurate molding of complex inner cavity structures, and solve the problem of large demolding resistance or product damage caused by complex inner cavities.

[0042] To achieve demolding of the steering gear housing, the demolding mechanism includes: three push rods 10, a sliding plate 11, five support rods 12, a rotating frame 13, a turntable 14, and a push rod 15;

[0043] The top of the ejector rod 10 extends into the lower mold 2. The ejector rod 10 is fixedly installed on the top of the sliding plate 11. The support rod 12 is fixedly installed on the top of the base 1. The top of the support rod 12 slides in contact with the bottom of the sliding plate 11. The rotating frame 13 is fixedly installed on the top of the base 1. The turntable 14 is rotatably connected to the front side of the rotating frame 13. The push rod 15 is rotatably connected to the sliding plate 11 and the turntable 14 respectively. The three ejector rods 10 are connected to the sliding plate 11 and extend into the lower mold 2. The support rod 12 provides sliding support for the sliding plate 11. The rotating turntable 14 drives the sliding plate 11 to move up and down through the push rod 15, thereby simultaneously driving the three ejector rods 10 to eject the casting. This centralized operation structure utilizes the lever principle to uniformly lift the complex shell with a smaller operating force, effectively overcoming demolding resistance, significantly improving demolding efficiency and success rate, and reducing the risk of product damage.

[0044] In order to install the sliding plate 11, the bottom of the lower mold 2 is provided with symmetrically arranged vertical grooves.

The vertical grooves at the bottom of the lower mold 2 provide precise guidance for the sliding plate 11 to move up and down, ensuring that the ejector rod 10 moves smoothly and vertically, and avoiding damage to the casting due to uneven ejection.

[0045] In order to demold the steering gear housing, the bottom of the lower mold 2 is provided with multiple circular through holes arranged at equal intervals. The outer side of the ejector rod 10 slides in contact with the inner wall of the circular through holes. The circular through holes at the bottom of the lower mold 2 allow the ejector rod 10 to slide. The through holes form a tight constraint on the ejector rod 10, ensuring that the movement trajectory of the ejector rod 10 is accurate and the ejection position is accurate and reliable.

[0046] In order to achieve injection molding of the upper mold 7 and the lower mold 2, the top of the upper mold 7 is provided with two symmetrically arranged injection ports. The dual-inlet design of the symmetrical injection ports on the top of the upper mold 7 is conducive to the molten material filling the complex mold cavity more quickly and evenly, reducing injection defects and improving the quality of castings.

The second inner liner 6 fixes the rectangular block and slides in contact with the first inner liner 4. The rectangular block has a through hole that slides in cooperation with the round rod of the upper mold 7. This structure uses the round rod inserted into the through hole to assist in the precise positioning of the inner liner during mold closing, ensuring the accurate position of the inner liner and preventing misalignment from affecting the internal structural accuracy of the casting.

[0048] The working principle of this utility model is as follows: By setting up an inner lining mechanism and a demolding mechanism in conjunction with the mold mechanism, the first inner lining 4 is driven to move left and right by the first electric push rod 3, and the second inner lining 6 is driven to move back and forth by the second electric push rod 5. Both can slide to contact the inner walls of the upper and lower molds 2, respectively inserting into the left side and the rear side of the upper mold 7 and the lower mold 2. This structure can flexibly adapt to the shape changes of the steering gear housing cavity, ensuring accurate molding of complex inner cavity structures, and solving the problem of high demolding resistance or product damage caused by complex inner cavities. The demolding mechanism is specifically designed to solve the problem of difficult demolding. Three push rods 10 are connected to sliding plates 11. The support rod 12 extends into the lower mold 2, and provides sliding support for the sliding plate 11. The rotating turntable 14 drives the sliding plate 11 to move up and down through the push rod 15, thereby simultaneously driving the three push rods 10 to eject the casting. This centralized operation structure utilizes the lever principle to uniformly lift the complex shell with a smaller operating force, effectively overcoming demolding resistance, significantly improving demolding efficiency and success rate, and reducing the risk of product damage. The third electric push rod 8 drives the upper mold 7 to open and close, and the first and second electric push rods 5 drive the inner liner mechanism to move. The lower mold 2 is fixed to the base 1. The overall structure is designed for the complex shape of the steering gear shell, improving molding accuracy and demolding convenience.
