Description

Technical Field

[0001] This utility model relates to the field of casting molds, specifically a casting mold for the split body of a heavy industrial robot arm. Background Technology

[0002] The shapes of the main arms of heavy industrial robots are typically quite complex. To meet the requirements of their complex geometry and dimensional accuracy, the structure of the casting molds also becomes correspondingly complex. The mold interior requires numerous cores, cavities, and a complex runner system to shape the various parts of the main arm. These complex structures make the heat transfer path within the mold tortuous and lengthy, making it difficult to dissipate heat quickly and effectively. Therefore, existing casting molds for heavy industrial robot main arms generally suffer from slow cooling rates.

[0003] To address the aforementioned issues, a casting mold for the split arm of a heavy industrial robot is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a casting mold for the split arm of a heavy industrial robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a casting mold for a heavy-duty industrial robot boom, comprising a lower mold base and an upper mold base, wherein the lower mold base and the upper mold base are engaged and connected. A first cooling structure is fixedly disposed inside the lower mold base, and a second cooling structure is fixedly disposed inside the upper mold base. Both the first and second cooling structures include a first heat exchange pipe. Connecting pipes are fixedly connected to both ends of one side of the first heat exchange pipe. A second heat exchange pipe is fixedly connected to the end of the two connecting pipes away from the first heat exchange pipe. A first forming cavity is formed in the middle of the top of the lower mold base, and a second forming cavity is formed in the middle of the bottom of the upper mold base. The second forming cavity corresponds to the first forming cavity. The first and second cooling structures have identical structures and are respectively fixedly disposed inside the lower and upper mold bases. This design, which integrates the cooling structure inside the mold base, makes full use of the internal space of the mold base without occupying additional external space, making the overall structure of the mold more compact. At the same time, the close integration of the cooling structure with the mold base enables more effective cooling of the mold and improves cooling efficiency. Cold water is introduced into two second heat exchange pipes through two inlet pipes, and then into four connecting pipes and two first heat exchange pipes. After heat exchange between the cold water and the upper and lower mold bases, the cooling speed of the product is accelerated, thereby improving work efficiency. The multi-pipe series cooling method increases the contact area and contact time between the cooling medium and the mold, which can more quickly and evenly remove the heat absorbed by the mold during the casting process, effectively control the mold temperature, improve the cooling speed and cooling uniformity of the casting, and thus improve the internal structure and mechanical properties of the casting.

[0006] Preferably, positioning posts are fixedly provided at the four corners of the bottom of the upper mold base, and positioning holes are provided at the four corners of the top of the lower mold base. The four positioning holes are respectively set to correspond to the four positioning posts. Through the cooperation of the positioning posts and positioning holes, and the design of the upper and lower corresponding forming cavities, the mold can be guaranteed to have extremely high alignment accuracy when the mold is closed, thereby accurately forming the shape and size of the heavy industrial robot arm.

[0007] Preferably, an injection port is provided at the center of the top of the upper mold base, and the injection port is connected to the second molding cavity. The optimized injection port design can ensure that the molten metal is injected into the cavity evenly and stably, avoid problems such as molten metal splashing and eddy currents, and reduce defects such as porosity and slag inclusions inside the casting.

[0008] Preferably, a number of evenly distributed heat exchange fins are fixedly provided at the top end of the first heat exchange tube and at one end of the second heat exchange tube. The arrangement of heat exchange fins can improve heat exchange efficiency.

[0009] Preferably, a cold water inlet pipe is fixedly connected to the middle of the side of the first heat exchange tube away from the connecting pipe, and a water outlet pipe is fixedly connected to the middle of the side of the second heat exchange tube away from the connecting pipe. The end of the water outlet pipe away from the second heat exchange tube and the end of the cold water inlet pipe away from the first heat exchange tube both extend to the outside.

[0010] Preferably, the upper mold base has a first decorative groove on its front side.

[0011] Preferably, the lower mold base has a second decorative groove on its front side.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the first cooling structure and the second cooling structure have the same structure and are respectively fixedly installed inside the lower mold base and the upper mold base. This design of integrating the cooling structure inside the mold base makes full use of the internal space of the mold base and does not occupy the external space of the mold, making the overall structure of the mold more compact. At the same time, the cooling structure is closely integrated with the mold base, which can cool the mold more effectively and improve the cooling efficiency. Cold water is introduced into the two second heat exchange pipes through two cold water inlet pipes, and then into the four connecting pipes and the two first heat exchange pipes. After the cold water exchanges heat with the upper mold base and the lower mold base, the cooling speed of the product is accelerated, thereby improving the working efficiency. Through the multi-pipe series cooling method, the contact area and contact time between the cooling medium and the mold are increased, which can remove the heat absorbed by the mold during the casting process more quickly and evenly, effectively control the mold temperature, improve the cooling speed and cooling uniformity of the casting, and thus improve the internal structure and mechanical properties of the casting.

[0017] In this embodiment, the first cooling structure 4 and the second cooling structure 7 have the same structure and are respectively fixedly installed inside the lower mold base 1 and the upper mold base 5. This design, which integrates the cooling structure inside the mold base, makes full use of the internal space of the mold base without occupying additional external space of the mold, making the overall structure of the mold more compact. At the same time, the cooling structure is closely integrated with the mold base, which can more effectively cool the mold and improve the cooling efficiency. Cold water is introduced into the two second heat exchange pipes 43 through two cold water inlet pipes 45, and then into the four connecting pipes 43 and the two first heat exchange pipes 41. After the cold water exchanges heat with the upper mold base 5 and the lower mold base 1, the cooling speed of the product is accelerated, thereby improving the working efficiency. The cooling method of multi-pipe series increases the contact area and contact time between the cooling medium and the mold, which can more quickly and evenly remove the heat absorbed by the mold during the casting process, effectively control the mold temperature, improve the cooling speed and cooling uniformity of the casting, and thus improve the internal structure and mechanical properties of the casting.

The lower mold base 1 and the upper mold base 5 are engaged and connected. A first cooling structure 4 is fixedly installed inside the lower mold base 1, and a second cooling structure 7 is fixedly installed inside the upper mold base 5. Both the first cooling structure 4 and the second cooling structure 7 include a first heat exchange pipe 41. Both ends of one side of the first heat exchange pipe 41 are fixedly connected to a connecting pipe 42, and the end of the two connecting pipes 42 away from the first heat exchange pipe 41 is fixedly connected to a second heat exchange pipe. 43. A first forming cavity 2 is formed at the center of the top of the lower mold base 1, and a second forming cavity 9 is formed at the center of the bottom of the upper mold base 5.

The first cooling structure 4 and the second cooling structure 7 have the same structure and are respectively fixedly installed inside the lower mold base 1 and the upper mold base 5. This design of integrating the cooling structure inside the mold base makes full use of the internal space of the mold base and does not occupy the external space of the mold, making the overall structure of the mold more compact. At the same time, the cooling structure is closely integrated with the mold base, which can cool the mold more effectively and improve the cooling efficiency. Cold water is introduced into the two second heat exchange pipes 43 through the two cooling water inlet pipes 45, and then into the four connecting pipes 43 and the two first heat exchange pipes 41. After the cold water exchanges heat with the upper mold base 5 and the lower mold base 1, the cooling speed of the product is accelerated, thereby improving the working efficiency. Through the cooling method of multiple pipes in series, the contact area and contact time between the cooling medium and the mold are increased, which can remove the heat absorbed by the mold during the casting process more quickly and evenly, effectively control the mold temperature, improve the cooling speed and cooling uniformity of the casting, and thus improve the internal structure and mechanical properties of the casting.

[0019] In use, the positioning pins 6 and positioning holes 3, along with the design of corresponding upper and lower forming cavities, ensure that the mold has extremely high alignment accuracy when the mold is closed. This allows for precise forming of the shape and size of the heavy industrial robot arm, effectively reducing casting defects and improving the quality and consistency of the castings. The optimized injection port 8 design ensures that the molten metal is injected into the cavity uniformly and stably, avoiding problems such as molten metal splashing and eddies, and reducing defects such as porosity and inclusions inside the castings.

Cold water is introduced into two second heat exchange pipes 43 through two cold water inlet pipes 45, and then into four connecting pipes 43 and two first heat exchange pipes 41. After the cold water exchanges heat with the upper mold base 5 and the lower mold base 1, the cooling speed of the product is accelerated, thereby improving work efficiency. The cooling method of multi-pipe series increases the contact area and contact time between the cooling medium and the mold, which can remove the heat absorbed by the mold during the casting process more quickly and evenly, effectively control the mold temperature, improve the cooling speed and cooling uniformity of the casting, and thus improve the internal structure and mechanical properties of the casting.

[0021] In this application embodiment, the design of the two decorative grooves is not merely for aesthetic purposes, but also has multiple practical significances. From the perspective of product identification, product model, manufacturer, production date, and other information can be engraved or printed in the decorative grooves, facilitating product identification and management during production, storage, and sales. Even after the mold has been used for a period of time, this information can still be clearly retained, helping to trace the product's production source and quality information. From the perspective of mold maintenance, the decorative grooves can serve as an observation window for the mold's condition. During the use of the mold, due to long-term exposure to high temperatures and pressures, defects such as wear and cracks may occur. By observing the surface condition around the decorative grooves, such as whether there is discoloration or peeling, the damage inside the mold can be preliminarily judged, and potential problems can be detected in time for repair or replacement, avoiding production accidents or the generation of a large number of scraps due to mold failure.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
