Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a low-pressure casting mold for an automobile wheel hub. Background Art

[0002] The automobile wheel hub is the part in the center of the wheel where the axle is mounted. It is also called the rim or steel rim. The wheel hub is a cylindrical metal component whose inner profile supports the tire. The center is mounted on the axle and is used to connect the brake drum or brake disc, wheel disc and half-axle, and cooperate with the tire to support the wheel.

[0003] When making automobile wheels, liquid raw materials are generally poured into a dedicated mold and gradually cooled before being shaped. However, in the existing technology, most automobile wheel molds have a tight fit between the liquid raw materials and the inner wall of the mold, which makes it easy for the automobile wheel to adhere to the inner wall of the mold, making it difficult to quickly demold the automobile wheel after molding. In addition, there is no cooling device inside the mold, so the liquid raw materials solidify and shape slowly in the mold, which affects the processing efficiency of the automobile wheel and is not practical. Therefore, it is necessary to redesign a low-pressure casting mold for automobile wheels to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a low-pressure casting mold for an automobile wheel hub.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 A low-pressure casting mold for an automobile wheel hub includes a base 1. A plurality of supporting legs 2 are fixedly installed on the bottom wall of the base 1. A lower mold 3 is fixedly installed on the upper end surface of the base 1 through a fixing groove. A lifting plate 4 is slidably installed on the inner wall of the lower mold 3. A cylinder 6 is fixedly installed on the bottom wall of the lower mold 3 through a fixed frame 5. A push plate 9 is fixedly installed on the telescopic end of the cylinder 6. A limit plate 8 is fixedly installed on the bottom wall of the push plate 9 through a stabilizing mechanism. The stabilizing mechanism includes two stabilizing rods 7 fixedly installed on the bottom wall of the push plate 9. The two stabilizing rods 7 slide through the fixed frame 5. The push plate 9 cooperates with the lifting plate 4. The upper end surface of the base 1 is fixedly installed with a movable frame 1 through a supporting mechanism. 1. The supporting mechanism includes a supporting plate 10 fixedly mounted on the upper end surface of the base 1, a moving frame 11 fixedly mounted on the bottom wall of the supporting plate 10, a double-headed screw 12 is rotatably mounted on the inner wall of the moving frame 11, a motor 13 connected to the double-headed screw 12 is fixedly mounted on the outer wall of the moving frame 11, two moving sleeves 15 are threadedly mounted on the outer wall of the double-headed screw 12 through a limiting mechanism, and the limiting mechanism includes a limiting rod 14 fixedly mounted on the inner wall of the moving frame 11, the limiting rod 14 slides through the two moving sleeves 15, and the limiting rod 14 can limit the two moving sleeves 15 so that the two moving sleeves 15 can only move axially along the outer wall of the double-headed screw 12.

[0023] The bottom walls of the two movable sleeves 15 are fixedly mounted with a first connecting frame 16, and the interiors of the two first connecting frames 16 are rotatably connected to the second connecting frame 18 through a connecting mechanism. The connecting mechanism includes a connecting plate 17 rotatably mounted inside the first connecting frame 16, and the end of the connecting plate 17 is rotatably connected to the interior of the second connecting frame 18. The bottom walls of the two second connecting frames 18 are jointly mounted with an upper mold 19. Two fixed plates 20 are fixedly mounted on the upper end surface of the base 1, and a refrigerator 22 is fixedly mounted on the inner walls of the two fixed plates 20 through a telescopic mechanism. The refrigerator 22 is a semiconductor refrigerator, which does not use refrigerant, so there is no leakage and no pollution to the environment. The semiconductor refrigerator has a fast action speed, reliable operation, long service life, easy control, and convenient adjustment. The refrigeration capacity of the regulator can be adjusted by adjusting the working current. The telescopic mechanism includes an electric push rod 21 fixedly mounted on the outer wall of the fixed plate 20, and the telescopic end of the electric push rod 21 is fixedly connected to the outer wall of the refrigerator 22.

[0024] When the utility model is used, the liquid raw material is first put into the lower mold 3, and then the motor 13 drives the double-headed screw 12 to rotate. When the double-headed screw 12 rotates, it can drive the two movable sleeves 15 to move by cooperating with the limit rod 14, and the two movable sleeves 15 then respectively drive the first connecting frame 16 on the same side to move, thereby making the two first connecting frames 16 respectively drive the upper mold 19 to move through the cooperation of the connecting plate 17 and the second connecting frame 18, so that the upper mold 19 can contact the liquid raw material in the lower mold 3. The manufacturing of the automobile wheel hub can be realized through the cooperation of the upper mold 19 and the lower mold 3. When the automobile wheel hub is formed, the refrigerators 22 on both sides of the lower mold 3 can be driven to move to its outer wall to fit therewith under the telescopic action of the two electric push rods 21. The automobile wheel hub inside the mold can be cooled by the conduction of the temperature of the refrigerator 22, thereby accelerating the efficiency of cooling and molding of the automobile wheel hub, and at the same time improving the working efficiency of automobile wheel hub manufacturing;

[0025] At the same time, after the automobile wheel hub is cooled and formed, the lifting plate 4 can be driven to move upward by cooperating with the push plate 9 under the telescopic action of the cylinder 6. The push plate 9 can increase its stability during movement through two stabilizing bars 7 to prevent the push plate 9 from pushing the lifting plate 4 and causing the automobile wheel hub on its upper end surface to fall off. Subsequently, the lifting plate 4 can stably push the formed automobile wheel hub upward from the inside of the mold during movement, thereby facilitating the demoulding of the automobile wheel hub and preventing it from being stuck in the mold and unable to be removed, affecting subsequent work.
