Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing reducer housings, in particular to a molding die-casting device for reducer housings. Background Art

[0002] With the rapid development of modern industrial technology, reducers are indispensable transmission devices in various mechanical equipment. Their performance and stability directly affect the operating efficiency and safety of the entire mechanical system. Reducer housing is a key component of the reducer. Its molding quality is directly related to the overall performance and service life of the reducer. With the continuous development of die-casting technology, its application in the field of metal forming is becoming more and more extensive, especially in the manufacturing of parts with complex shapes and high precision requirements. It has shown significant advantages.

[0003] For example, patent CN202210450185.0 discloses a stamping forming equipment for manufacturing reducer housing. In the present invention, the hydraulic cylinder drives the connecting plate and the U-shaped plate to descend, and the extrusion plate connected to the connecting plate contacts the rectangular plate. When the sharp corner of the extrusion plate contacts the inner side of the rectangular plate, the rectangular plate has moved outward to the maximum extent, giving the reducer housing enough falling space. The reducer housing falls onto the rotating plate and slides slowly. During this period, the extrusion plate continues to descend and then fills the space to prevent the housing from continuing to fall. Then the pressure plate has pushed the cross plate outward, and the roller moves outward indirectly to ensure that the housing can slide smoothly to the rotating plate. The stamping operation is carried out in an orderly manner with a low probability of error, thereby improving the stamping efficiency.

[0004] However, during the die-casting operation, the temperature of the die-casting parts will be very high after being die-cast and needs to be cooled immediately to improve its mechanical properties and dimensional stability. Traditional die-casting equipment often lacks a mechanism for fast and effective cooling of die-casting parts, which makes it easy for die-casting parts to have defects such as deformation and cracks after molding, reducing the product qualification rate.

[0005] Based on this, the utility model designs a molding die-casting device for a reducer housing to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4, a die-casting device for forming a reducer housing, a workbench 1, a die-casting mechanism 2 and a cooling mechanism 3, characterized in that: the die-casting mechanism 2 and the cooling mechanism 3 are arranged on the top of the workbench 1, the top of the workbench 1 is fixedly connected with a slide rail 4, the die-casting mechanism 2 comprises a die-casting mold 1 21, a die-casting mold 2 22 and a clamping assembly 23, the die-casting mold 1 21 is fixedly connected to the right side of the top of the workbench 1, the die-casting mold 2 22 is arranged on the left side of the die-casting mold 2 22, the bottom of the die-casting mold 2 22 is slidably connected to the slide rail 4, and the left side of the die-casting mold 2 22 is drivingly connected with the clamping assembly 23;

[0024] The cooling mechanism 3 includes a fixed frame 31, a horizontal moving component 32, a vertical moving component 33 and a cooling component 34. The fixed frame 31 is fixedly connected to the top of the workbench 1, the horizontal moving component 32 is fixedly installed on the top of the fixed frame 31, the vertical moving component 33 is movably connected to the horizontal moving component 32, and the cooling component 34 is movably connected to the horizontal moving component 32.

[0025] Specifically, when in use, the movable mold part of the die-casting mechanism 2, that is, the die-casting mold 2 22, is driven by the mold clamping assembly 23 to move horizontally on the slide rail 4, so that the die-casting mold 1 21 and the die-casting mold 2 22 are separated or closed, ensuring that the mold remains tightly closed during injection filling, and the injection mechanism is used to push the molten metal into the mold cavity composed of the die-casting mold 1 21 and the die-casting mold 2 22 to fill the workpiece formed into a die-casting part. The die-casting workpiece is driven again by the mold clamping assembly 23 to separate the die-casting mold 1 21 and the die-casting mold 2 22, and the cooling mechanism 3 is started, and the horizontal moving assembly 32 is used to drive the cooling mechanism 3 to move. The cooling component 34 moves horizontally to the top between the die-casting mold 1 21 and the die-casting mold 2 22, and the cooling component 34 is driven by the vertical moving component 33 to move vertically downward to the right side of the die-casting. Then, the die-casting is spray-cooled by the nozzle 343 in the cooling component 34, so as to quickly reduce the temperature of the die-casting, and quickly solidify the die-casting, thereby improving production efficiency and product quality. At the same time, through the synergistic effect of the horizontal moving component 32 and the vertical moving component 33, the cooling component 34 can be flexibly moved to the top of the die-casting at different positions for cooling, which greatly improves the flexibility and applicability of the equipment.

[0026] Furthermore, the horizontal moving assembly 32 includes a mounting frame 321, a servo motor 322 and a lead screw 323. The mounting frame 321 is fixedly connected to the top of the fixing frame 31. The servo motor 322 is fixedly installed on the right side of the inner cavity of the mounting frame 321. The output end of the left side of the servo motor 322 is fixedly connected to the lead screw 323. The lead screw 323 is rotatably connected in the mounting frame 321. After the servo motor 322 is started, its rotational power is transmitted to the lead screw 323 through the output end, so that the lead screw 323 rotates in the inner cavity of the mounting frame 321. The rotation of the lead screw 323 drives The slider 331 threadedly connected thereto moves linearly in the horizontal direction, thereby realizing precise horizontal position adjustment of the cooling assembly 34. In addition, in order to ensure the stability and accuracy of the slider 331 during the horizontal movement, the inner cavity of the mounting frame 321 can be designed with a corresponding guide structure so that the slider 331 can slide smoothly within a limited track. At the same time, the servo motor 322 realizes precise speed and steering control through the control system, ensuring the accuracy of the moving speed and position of the slider 331 and the cooling assembly 34.

[0027] Furthermore, the vertical moving component 33 includes a slider 331, and the internal thread of the slider 331 is connected to the screw 323. The slider 331 is slidably connected to the mounting frame 321 through the screw 323. In the vertical direction, through the coordinated action of the vertical moving component 33, the cooling component 34 can be accurately moved vertically to the top of the die casting.

[0028] Furthermore, the vertical moving component 33 also includes a fixed plate 332, a guide rail 333 and a slider 2 334. The fixed plate 332 is fixedly connected to the front side of the slider 1 331. The guide rail 333 is fixedly installed on the front side of the fixed plate 332. The slider 2 334 is slidably connected to the guide rail 333. When the cooling component 34 needs to be moved vertically, the slider 2 334 slides on the guide rail 333 to drive the cooling component 34 connected thereto to move vertically up and down.

[0029] Furthermore, the cooling assembly 34 includes a connecting plate 341, a conveying block 342, a nozzle 343 and a water inlet 344. The connecting plate 341 adopts an L-shaped structure, which provides a stable connection for the entire cooling assembly 34. The top of the connecting plate 341 is fixedly connected to the front side of the slider 334, and the bottom of the connecting plate 341 is fixedly connected to the conveying block 342. A number of nozzles 343 are fixedly installed at equal intervals on the bottom of the conveying block 342. A water inlet 344 is opened on the front side of the conveying block 342. The water inlet 344 is externally connected to a cooling water source to ensure that the nozzle 343 can continuously supply cooling water, so that the cooling assembly 34 can evenly cover the surface of the die-casting during spray cooling, effectively improving the cooling efficiency and cooling uniformity, and further ensuring product quality.

[0030] Specifically, when the cooling component 34 moves to one side of the die-casting under the joint action of the horizontal moving component 32 and the vertical moving component 33, the cooling water source enters the conveying block 342 through the water inlet 344, and is evenly sprayed on the die-casting through the nozzle 343. The nozzle 343 enables the cooling water to form a fine water mist, thereby increasing the contact area with the die-casting, accelerating the heat transfer, and achieving rapid cooling. At the same time, since the nozzles 343 are installed at equal intervals on the conveying block 342, the cooling uniformity of various parts of the die-casting surface can be ensured, thereby avoiding product quality problems caused by local overheating or overcooling.

[0031] Furthermore, the clamping assembly 23 is fixedly installed on the right side of the top of the workbench 1, and the die-casting mold 2 22 is slidably connected to the slide rail 4 through the clamping assembly 23. The clamping assembly 23 is a commonly used elbow clamping method in the prior art. When the pressure oil enters the clamping cylinder, the clamping piston is pushed to drive the connecting rod, so that the triangular hinge swings around the fulcrum, and the force is transmitted to the movable mold mounting plate through the force arm, generating a clamping action, thereby closing the die-casting mold 1 21 and the die-casting mold 2 22 to facilitate subsequent die-casting operations.

[0032] The working principle of the utility model is as follows: after the die casting is completely cooled and solidified, the mold clamping assembly 23 is started again, pushing the die casting mold 22 to slide on the slide rail 4, so that the die casting mold 1 21 and the die casting mold 22 are separated, so that the die casting workpiece is exposed to the outside, and the cooling mechanism 3 will start quickly to cool the die casting. At this time, the servo motor 322 receives the command of the control system and starts to rotate, driving the lead screw 323 to rotate in the inner cavity of the mounting frame 321. The rotation of the lead screw 323 drives the slider 1 331 to move linearly in the horizontal direction, so that the cooling assembly 34 connected to the slider 1 331 moves horizontally to the upper part between the die casting mold 1 21 and the die casting mold 2 22. When the cooling assembly 34 moves to the appropriate position, the vertical moving assembly 3 3 starts to work. Under the guidance of the guide rail 333, the slider 334 drives the connecting plate 341 and the cooling assembly 34 to move in the vertical direction, ensuring that the nozzle 343 can accurately reach one side of the die casting. At the same time, the cooling water source is transported to the conveying block 342 through the water inlet 344, and then evenly sprayed on the die casting by the nozzle 343 at the bottom of the conveying block 342. The mist-like cooling water quickly covers the surface of the die casting, increases the contact area with the die casting, accelerates the heat transfer, and realizes rapid cooling. During the cooling process, the cooling mechanism 3 can flexibly move to the top of the die castings at different positions for cooling through the coordinated action of the horizontal moving assembly 32 and the vertical moving assembly 33, ensuring that all the die castings can be cooled in time and evenly.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
