Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and more specifically, to a high-efficiency cooling die casting mold. Background Technology

[0002] A die-casting mold is a component that presses sheet metal into a certain shape. A die-casting mold includes an upper mold and a lower mold. The lower mold has a lower cavity on top, and the upper mold has an upper cavity on the bottom. The lower cavity and the upper cavity are combined to form an integral mold cavity, in which the product is formed.

[0003] A search revealed that Chinese patent CN214920385U discloses a molding die for magnesium-aluminum alloy die castings, relating to the field of die casting mold technology. The use of a demolding mechanism facilitates the ejection of the molded product from the lower mold cavity, making it easier for workers to remove the product from the lower mold and preventing collisions between the product and the cavity. This also improves production efficiency.

[0004] While the aforementioned die-casting molds facilitate the removal of the molded product from the workpiece during use, the lack of a rapid heat dissipation structure after processing makes the molded workpiece, due to its high temperature, susceptible to burns. Furthermore, although the workpiece has already taken shape, using clamps to handle it at high temperatures can easily damage it. Therefore, how to rapidly dissipate heat from the molded workpiece is a problem that needs to be solved. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-efficiency cooling die casting mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cooling die-casting mold, comprising a lower mold base, a mold cavity at the top of the lower mold base, a heat exchange assembly installed inside the lower mold base at a position outside the mold cavity, and a vertical plate fixedly connected to the top edge of the lower mold base along the vertical direction. A top plate is fixedly connected to the top outer wall of the vertical plate, a motor is installed on the top of the top plate, and a fixing plate is fixedly connected to the middle outer wall of the vertical plate at a position below the top plate. A rotating shaft is connected vertically downward between the output end of the motor and the top of the fixing plate. An externally fixed rotating plate is provided. A hydraulic cylinder is fixedly installed at the top center of the rotating plate.

A limit stop is fixedly connected vertically at the top end of the lower mold base near the outer side of the protruding plate. A horizontal bar is fixedly connected horizontally on the outer side wall of the end of the rotating plate near the vertical plate. Several fans are installed at the bottom of the horizontal bar. A control switch is installed on the outer wall of the vertical plate.

[0007] As a further improvement to the technical solution of this utility model, the heat exchange assembly includes a bottom heat exchange tube installed inside the lower mold base and located below the mold cavity. Both ends of the bottom heat exchange tube are connected to side heat dissipation tubes at positions on both sides of the mold cavity. One end of the side heat dissipation tube extends to the outside of the lower mold base and is provided with a water inlet. The other end of the side heat dissipation tube is connected to a return pipe, and one end of the return pipe extends to the outside of the lower mold base and is provided with a water outlet.

[0008] As a further improvement to the technical solution of this utility model, the heat exchange component is made of stainless steel, and the lower mold base is provided with a cavity for installing the heat exchange component.

[0009] As a further improvement to the technical solution of this utility model, the top plate and the fixed plate are welded to the outer wall of the vertical plate, and a bearing seat is provided at the top of the fixed plate corresponding to the end position of the rotating shaft.

[0010] As a further improvement to the technical solution of this utility model, the interior of the rotating plate is provided with a through hole for the piston movement at the output end of the hydraulic cylinder, and the exterior of the hydraulic cylinder is provided with a fixing frame, which is fixedly connected to the top of the rotating plate by screws.

[0011] As a further improvement to the technical solution of this utility model, the two ends of the lifting plate are fixedly connected with limit rods in the vertical direction on both sides of the hydraulic cylinder. The top of the limit rods passes through and extends to the top of the rotating plate. Limit holes are provided inside the rotating plate at the connection point of the limit rods.

[0012] As a further improvement to the technical solution of this utility model, the crossbar and the outer wall of the rotating plate are fixedly connected by welding or screws, and the fan is fixedly installed at the bottom of the crossbar by screws.

[0013] The beneficial effects of this utility model are:

[0014] 1. A heat exchange component is installed inside the lower mold base at a position outside the mold cavity. The heat exchange component consists of a bottom heat exchange pipe, a side heat dissipation pipe, a water inlet, a return pipe, and a water outlet. The entire heat exchange component is made of stainless steel and is used to circulate water with an external circulating water pump and water tank. Cold water enters the interior of the heat exchange component to exchange heat with the heat around the die-cast workpiece, thereby achieving a cooling effect.

[0015] 2. By setting a rotating air-cooled heat dissipation structure above the mold cavity, after the upper module is raised during die casting, the motor is controlled to drive the rotating shaft to rotate, which in turn controls the rotating plate to rotate.

[0028] Working principle: This utility model designs a high-efficiency cooling die-casting mold, the specific structure of which is shown in the attached instruction manual. Figure 1-4 As shown, in this technical solution, the liquid to be die-cast is poured into the mold cavity 2. The piston of the hydraulic cylinder 10 is extended to control the lifting plate 11 and the upper module 12 to descend and die-cast the workpiece. After die-casting, the piston of the hydraulic cylinder 10 is retracted to control the upper module 12 to rise and detach from the mold cavity 2, thus completing one die-casting process. A heat exchange component is installed inside the lower mold base 1 at a position outside the mold cavity 2. This heat exchange component consists of a bottom heat exchange pipe 21, a side heat dissipation pipe 22, a water inlet 19, a return pipe 23, and a water outlet 20. The entire heat exchange component is made of stainless steel and is used for water circulation with an external circulating water pump and water tank, allowing cold water to enter the interior of the heat exchange component. The heat around the die-cast workpiece is exchanged to achieve a cooling effect. At the same time, a rotating air-cooled heat dissipation structure is set above the mold cavity 2. When the die-casting process raises the upper module 12, the control motor 5 drives the rotating shaft 6 to rotate, which in turn controls the rotating plate 9 to rotate. The control fan 17 rotates to the upper position of the mold cavity 2 to dissipate heat from the workpiece inside the mold cavity 2, further improving the cooling treatment after the die-casting mold is processed. After the cooling is completed and the workpiece is removed, the rotor of the control motor 5 reverses to drive the rotating plate 9 to reset. The convex plate 14 and the limit stop 15 are set to limit the upper module 12 to accurately rotate to the upper position of the mold cavity 2 for the processing of the next workpiece.
