[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: an automotive gearbox mold with rapid cooling function, including a base 1, an upper mold 2, a core 3, a sprue 4, a lower mold 5, a cavity 6, a heat sink 7, a cooling pipe 8, a water outlet pipe 9, a water inlet pipe 10, a sliding plate 11, a telescopic rod 12, a first electric push rod 13, a limit block 14, and a second electric push rod 15.

[0031] An upper mold 2 is fixedly mounted on top of the base 1 via a bracket. A lower mold 5 is positioned below the upper mold 2. The outer surface of the lower mold 5 is aligned with the inner surface of the upper mold 2. The lower surface of the upper mold 2 is open, and the upper surface of the lower mold 5 is open. A core 3 is fixedly installed on the inner wall of the upper mold 2, and a cavity 6 is fixedly installed on the inner wall of the lower mold 5. The core 3 and the cavity 6 are engaged and matched. A sprue 4 is provided through the surface of the upper mold 2. The sprue 4 is a through-tube structure, and its lower end penetrates the surface of the core 3. A drive structure is provided on the upper surface of the base 1. The drive structure uses a first electric push rod 13 and a second electric push rod 15 to move the lower mold 5 in two directions, thereby realizing the mold closing and... The discharge and drive structure includes a sliding plate 11, which is slidably disposed on the upper surface of the base 1. A telescopic rod 12 is fixedly installed on the upper surface of the sliding plate 11, and the upper end of the telescopic rod 12 is fixed to the lower surface of the lower mold 5. A first electric push rod 13 is fixedly installed on the upper surface of the sliding plate 11, and the output end of the first electric push rod 13 is fixed to the lower surface of the lower mold 5. Limiting blocks 14 are respectively provided on both sides of the sliding plate 11. The limiting blocks 14 have an L-shaped structure and are fixedly installed on the upper surface of the base 1. The two sliding plates 11 constitute the limiting structure. A second electric push rod 15 is fixedly installed on the upper surface of the base 1, and the output end of the second electric push rod 15 is fixedly connected to the side surface of the sliding plate 11.

[0032] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, when using this device to mold an automotive gearbox, the second electric push rod 15 is activated. The second electric push rod 15 drives the sliding plate 11 to slide on the surface of the base 1. When the sliding plate 11 contacts the limit block 14, the second electric push rod 15 is stopped. At this time, the lower mold 5 and cavity 6 on the upper surface of the sliding plate 11 are aligned with the upper mold 2 and core 3. The first electric push rod 13 is then activated. The first electric push rod 13 drives the lower mold 5 and cavity 6 to rise, so that the lower mold 5 is inserted downward into the interior of the upper mold 2. At this time, the cavity 6 and the core 3 engage to complete the mold closing. Molten raw material is injected into the cavity 6 and the core 3 through the injection port 4 to form the automotive gearbox. After the product is formed, the first electric push rod 13 is activated to drive the lower mold 5 and the cavity 6 to descend, so that the lower mold 5 and the upper mold 2 are separated. The first electric push rod 13 is activated, and the first electric push rod 13 drives the sliding plate 11 to slide on the surface of the base 1, so that the upper mold 2 and the lower mold 5 are misaligned, exposing the upper end of the cavity 6, which facilitates the demolding of the formed product.

[0033] Cavity 6 is a hollow sandwich structure. An auxiliary heat dissipation structure is provided inside the sandwich of cavity 6. The auxiliary heat dissipation structure achieves rapid temperature exchange within cavity 6 through heat sinks 7, increasing the cooling speed of the device. The auxiliary heat dissipation structure includes heat sinks 7, which are embedded and fixed on the outer surface of cavity 6. Multiple heat sinks 7 are arranged in a ring on the outer surface of cavity 6. One end of heat sink 7 is inserted into the sandwich of cavity 6, and the other end of heat sink 7 is inserted into the interior of lower mold 5. The interior of lower mold 5 is hollow, and the outer surface of lower mold 5 is provided with circular ventilation holes. Upper mold 2 is a hollow sandwich structure. A water cooling structure is provided inside the sandwich of upper mold 2. The water cooling structure increases the heat dissipation efficiency of the device through cooling pipes 8. The water cooling structure includes cooling pipes 8, which are spirally arranged in the sandwich of upper mold 2. One end of cooling pipe 8 is connected to water outlet pipe 9, which is installed through the upper surface of upper mold 2. The other end of cooling pipe 8 is connected to water inlet pipe 10, which is installed through the side surface of upper mold 2.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inlet pipe 10 and outlet pipe 9 are connected to the water circulation mechanism, so that cooling water enters from the inlet pipe 10, enters the interior of the cooling pipe 8, and flows out from the outlet pipe 9. During the product molding process, the high temperature in the cavity 6 is transferred to the interior of the cavity 6, and the heat is concentrated on the heat sink 7. The heat is transferred along the heat sink 7 to the interior of the lower mold 5. The circular ventilation holes on the outer surface of the lower mold 5 allow the air inside to flow, realizing the rapid exchange of heat in the cavity 6 and reducing the temperature inside the cavity 6. At the same time, the inlet pipe 10 is connected to an external cold water source, and the cold water flows inside the cooling pipe 8. During the flow, the cold water fully absorbs the heat on the surface of the lower mold 5. The two work together to ensure that the mold temperature drops rapidly.

[0035] Working principle: When using this automotive gearbox mold with rapid cooling function, the first electric push rod 13 is activated, which drives the lower mold 5 to move upward, thereby causing the core 3 on the inner wall of the upper mold 2 to engage with the cavity 6 on the inner wall of the lower mold 5, completing the mold closing. The raw material is injected into the device through the injection port 4, and the raw material is formed in the cavity 6 and the core 3. During the product forming process, the high temperature in the cavity 6 transfers heat to the heat sink 7, and the heat is conducted to the interior of the lower mold 5 through the heat sink 7. The heat is dissipated into the surrounding air through the circular ventilation holes on the outer surface of the lower mold 5. At the same time, cooling water flows in the cooling pipe 8 in the upper mold 2 to further cool the device and ensure that the product solidifies and forms quickly. After the product cools and forms, the first electric push rod 13 is activated to drive the lower mold 5 downward to separate from the upper mold 2. The second electric push rod 15 is activated, which drives the sliding plate 11 to slide horizontally on the upper surface of the base 1, causing the lower mold 5 to be misaligned with the upper mold 2, which facilitates the demolding of the product and increases the overall practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
