Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a die-casting mold for the outer shell of livestock machinery. Background Technology

[0002] Livestock machinery refers to the mechanical equipment used in various stages of livestock production, including feeding, management, transportation, and processing. For example, feed processing machinery processes various raw materials into feed suitable for livestock; environmental control machinery regulates environmental parameters such as temperature, humidity, and ventilation within the farm to provide a favorable growth environment for livestock; and milking machinery efficiently collects milk. These machines play a crucial role in large-scale, modern livestock farming, significantly improving the efficiency and quality of livestock production.

[0003] Die-casting molds are molds used to produce various metal shells. In the die-casting process, molten metal is injected into the mold cavity under high pressure. After the metal cools and solidifies, the mold is opened to obtain shell products with specific shapes and sizes. For livestock machinery, the shell not only protects the internal mechanical parts from the influence of the external environment, such as preventing dust and moisture from entering and causing mechanical failure, but also improves the overall aesthetics and safety of the machinery.

[0004] The existing die-casting mold for livestock machinery shells has the following shortcomings:

[0005] On the one hand, existing die-casting molds rely on a limited range of heat dissipation methods, primarily natural cooling or simple air cooling. This makes it difficult to quickly remove the large amount of heat generated during the die-casting process, resulting in excessively high mold temperatures. This affects the cooling rate and solidification effect of the molten metal, ultimately negatively impacting the die-casting precision and surface quality of the livestock machinery shells. On the other hand, existing die-casting molds lack convenient and effective ejection structures after die-casting. They require manual operation or the use of additional complex tools to eject the formed shell workpieces, which is cumbersome, inefficient, and extremely inconvenient to use. This severely restricts the efficiency and large-scale production of the die-casting process for livestock machinery shells. Utility Model Content

Through the cooperation of metal heat dissipation fins, cooling medium flow path, and vortex fan and heat exhaust fan, the heat dissipation efficiency is greatly improved.

Dustproof nets are fixedly connected to both the front and rear sides of the inner surface of the through-channel groove. A connecting pipe is fixedly connected to the inner wall of the through-channel groove on the side away from the flow channel. Four through-tubes are fixedly connected to the side of the connecting pipe near the flow channel. The end of the through-tube away from the connecting pipe extends into the inner surface of the flow channel.

[0010] Preferably, a connection port is fixedly connected to the rear side of the connecting pipe away from the conductive pipe, and the end of the connection port away from the conductive pipe extends through to the outside of the connecting slide plate.

[0011] Preferably, a rotating shaft running through the front and rear is rotatably connected to the middle of the four conductive tubes, and four vortex fans are fixedly connected to the outer surface of the rotating shaft, with the vortex fans rotatably connected to the middle of the conductive tubes.

[0012] Preferably, a heat exhaust fan is fixedly connected to the rear end of the rotating shaft, and the heat exhaust fan is rotatably connected inside the guide groove.

[0013] Preferably, the top of the die-casting lower template is provided with a cavity, and the lower surface of the inner wall of the cavity is provided with a plurality of ejection holes.

[0015] Preferably, a tightening spring is fixedly connected to the outer side of the bottom end of the sliding column, and the bottom end of the tightening spring is fixedly connected to the lower surface of the inner wall of the limiting slide groove.

[0016] Preferably, a connecting column is fixedly connected to the middle of the bottom end of the sliding column, and a sliding groove is provided in the middle of the bottom end of the die-casting lower template.

[0017] Preferably, the bottom ends of the four connecting columns all penetrate into the interior of the sliding groove and are fixedly connected to a sliding push plate, wherein the outer surface of the sliding push plate is slidably connected to the inner surface of the sliding groove.

[0018] Preferably, a mounting plate is fixedly connected to the top center of the sliding push plate, and a plurality of ejector rods are fixedly installed on the top of the mounting plate.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0020] 1. In this utility model, when the mold generates heat during the die-casting process, the heat is conducted to the metal heat dissipation fins. At the same time, the connecting pipe can be connected to a cooling medium through the connecting port. The cooling medium flows in the connecting pipe and the guide pipe. When it flows through the flow groove, it can quickly remove the heat from the lower die-casting mold. In addition, the vortex fan in the guide pipe rotates under the action of the cooling medium flow, which further enhances the turbulence of the cooling medium in the guide pipe and increases the heat exchange efficiency. The exhaust fan rotates in the guide groove and exhausts the air heated by the metal heat dissipation fins in the guide groove, forming an air flow to assist in heat dissipation. Through the cooperation of the metal heat dissipation fins, the flow path of the cooling medium, and the vortex fan and the exhaust fan, the heat dissipation efficiency is greatly improved, the mold temperature is effectively reduced, and the molten metal can be cooled and solidified quickly and evenly, thereby improving the die-casting precision and surface quality of the livestock machinery shell.

[0021] 2. In this utility model, after die casting is completed, an upward force is applied to the upper mold base to separate it from the lower mold base. At this time, the clamping spring is in a compressed state, and the elastic force it generates pushes the sliding column upward, thereby driving the connecting column and the sliding push plate to move upward. The mounting plate and the ejector rod rise accordingly. The ejector rod passes through the ejector hole and ejects the formed livestock machinery shell workpiece from the cavity. Through the cooperation between the clamping spring, the sliding column, the connecting column, the sliding push plate, the mounting plate and the ejector rod, a convenient and efficient automatic ejection function is achieved. There is no need for manual operation or the use of additional complex tools, which greatly improves the efficiency of the die casting process of livestock machinery shells and is conducive to large-scale production.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a technical solution: it includes a lower mold base 1, an upper mold base 2 slidably connected to the top of the lower mold base 1, a die-casting lower template 3 fixedly installed in the middle of the upper surface of the lower mold base 1, a die-casting upper template 4 fixedly installed in the middle of the lower surface of the upper mold base 2, heat dissipation components 5 fixedly installed on both the left and right sides of the die-casting lower template 3, an ejection component 6 slidably connected to the middle of the bottom end of the lower mold base 1, connecting grooves 34 are opened in the middle of the left and right sides of the die-casting lower template 3, four through-flow grooves 35 are opened on the opposite surfaces of the two connecting grooves 34, a plurality of metal heat dissipation fins 36 are fixedly connected to the inner surface of the connecting grooves 34, the heat dissipation component 5 includes a connecting slide plate 51, two connecting slide plates 51 are respectively fixedly installed on the left and right sides of the die-casting lower template 3 and slidably connected to the inner surface of the connecting grooves 34, a through-flow groove 52 is opened in the middle of the connecting slide plate 51, and the metal heat dissipation fins 36 are far from the middle of the die-casting lower template 3. One end of the connecting slide 34 extends into the interior of the guide groove 52. Dustproof nets 53 are fixedly connected to both the front and rear sides of the inner surface of the guide groove 52. A connecting pipe 54 is fixedly connected to the inner wall of the guide groove 52 away from the flow groove 35. Four guide pipes 55 are fixedly connected to the side of the connecting pipe 54 close to the flow groove 35. The end of the guide pipe 55 away from the connecting pipe 54 extends into the inner surface of the flow groove 35. A connecting port 56 is fixedly connected to the rear of the side of the connecting pipe 54 away from the guide pipe 55. The end of the connecting port 56 away from the guide pipe 55 extends into the exterior of the connecting slide plate 51. A rotating shaft 57 that extends from front to back is rotatably connected to the middle of the four guide pipes 55. Four vortex fans 58 are fixedly connected to the outer surface of the rotating shaft 57. The vortex fans 58 are rotatably connected to the middle of the guide pipes 55. A heat exhaust fan 59 is fixedly connected to the rear end of the rotating shaft 57. The heat exhaust fan 59 is rotatably connected to the interior of the guide groove 52.

[0031] The overall effect of Embodiment 1 is as follows: During the die casting process, the heat generated by the mold is rapidly transferred to the metal heat dissipation fins 36 on the lower die casting template 3. The cooling medium is connected to the external cooling medium through the connection port 56. After flowing into the connecting pipe 54, the cooling medium enters the flow groove 35 through the conduction pipe 55. Utilizing the good thermal conductivity of the metal heat dissipation fins 36, the heat on the lower die casting template 3 can be efficiently removed. At the same time, the flow of the cooling medium drives the vortex fan 58 in the conduction pipe 55 to rotate, which enhances the turbulence of the cooling medium in the conduction pipe 55 and further improves the heat exchange efficiency. The exhaust fan 59 rotates in the conduction groove 52 to exhaust the air heated by the metal heat dissipation fins 36, forming an airflow to assist in heat dissipation. This effectively reduces the mold temperature and ensures that the molten metal can cool and solidify quickly and evenly, thereby improving the die casting precision and surface quality of the livestock machinery shell.

[0032] Example 2: Figure 2 and Figure 5As shown, this utility model provides a technical solution: a cavity 31 is provided at the top of the die-casting lower template 3, and a plurality of ejection holes 32 are provided on the lower surface of the inner wall of the cavity 31. Two limiting grooves 33 are provided on both the front and rear sides of the upper surface of the die-casting lower template 3. The ejection assembly 6 includes four sliding pillars 61, which are slidably connected above the inner surface of the limiting grooves 33. A clamping spring 62 is fixedly connected to the outer side of the bottom end of the sliding pillar 61, and the bottom end of the clamping spring 62 is fixedly connected to the lower surface of the inner wall of the limiting groove 33. A connecting column 63 is fixedly connected to the bottom center of the sliding column 61. A sliding groove is opened in the bottom center of the die-casting lower template 3. The bottom ends of the four connecting columns 63 all penetrate into the interior of the sliding groove and are fixedly connected to a sliding push plate 64. The outer surface of the sliding push plate 64 is slidably connected to the inner surface of the sliding groove. A mounting plate 65 is fixedly connected to the top center of the sliding push plate 64. Several ejector rods 66 are fixedly installed on the top of the mounting plate 65. The top of the ejector rods 66 penetrates the ejector hole 32 and is slidably connected to the wall of the ejector hole 32.

[0033] The effect achieved by the entire embodiment 2 is as follows: After the die casting is completed, the upper mold base 2 is lifted upward. At this time, the top spring 62 is in a compressed state. The elastic force generated by it pushes the sliding column 61 to move upward along the limiting slide groove 33. The rise of the sliding column 61 drives the connecting column 63 to rise synchronously, thereby causing the sliding push plate 64 to move upward in the sliding groove. When the sliding push plate 64 moves upward, the mounting plate 65 and the ejector rod 66 fixed at its top also rise. The ejector rod 66 passes through the ejector hole 32 and ejects the formed livestock machinery shell workpiece from the cavity 31. This realizes a convenient and efficient automatic ejection function, without the need for manual operation or additional complex tools, which greatly improves the efficiency of the livestock machinery shell die casting process and is conducive to large-scale production.

[0034] The working principle of the entire equipment is as follows: When performing die casting of livestock machinery shells, the upper mold base 2 and the lower mold base 1 are first closed. Molten metal is injected under high pressure into the cavity 31 formed by the upper die casting template 4 and the lower die casting template 3 through the feed port on the upper mold base 2. During the die casting process, the mold generates a large amount of heat due to the injection and solidification of the molten metal. The heat is transferred to the metal heat dissipation fins 36 of the lower die casting template 3. The external cooling medium enters the connecting pipe 54 through the connecting port 56, and then flows into the flow channel 35 through the guide pipe 55. During the flow process, the cooling medium exchanges heat with the lower die casting template 3, carrying away the heat. At the same time, the cooling medium... The flow of the medium drives the vortex fan 58 to rotate, enhancing the heat exchange efficiency. The exhaust fan 59 discharges the hot air in the guide groove 52 to assist in heat dissipation, reduce the mold temperature, and ensure that the molten metal can cool and solidify quickly and evenly. After the die casting is completed, the upper mold base 2 is moved upward. At this time, the tension spring 62 releases its elasticity and pushes the sliding column 61 to move upward. The sliding column 61 drives the sliding push plate 64 to slide upward in the sliding groove through the connecting column 63. The sliding push plate 64 drives the mounting plate 65 and the ejector rod 66 to rise. The ejector rod 66 passes through the ejector hole 32 and ejects the formed livestock machinery shell workpiece from the cavity 31, completing the entire die casting and workpiece ejection process.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
