[0030] Please see Figure 1-7 This utility model provides a technical solution:

[0031] A mold cooling system for a zinc alloy production line includes an upper mold 1, a hydraulic rod 2, and a lower mold assembly 3. The hydraulic rod 2 is fixedly connected to the bottom of the upper mold 1, and its bottom is fixedly connected to the inner side of the lower mold assembly 3. A conveying assembly 5 is fixedly connected to the inner side of the lower mold assembly 3, and a cooling assembly 4 is fixedly connected to the top of the conveying assembly 5. The lower mold assembly 3 includes a lower mold shell 31, a lower mold base 32 fixedly connected to the upper end of the lower mold shell 31, a square groove 33 formed on the inner side of the lower mold shell 31 near the square groove 33, a column groove 34 formed on the inner side of the lower mold shell 31, an electric telescopic rod 35 fixedly connected to the inner side of the lower mold shell 31, and a guide rod fixedly connected to the bottom end of the lower mold base 32. The hot copper plate 36 and the cooling component 4 include a vertical plate 41. A first through hole 42 is opened on the inner side of the vertical plate 41. A second through hole 43 is opened on the inner side of the vertical plate 41 near the first through hole 42. A third through hole 44 is opened on the inner side of the vertical plate 41. The conveying component 5 includes a slide plate 51. A rubber ring 52 is fixedly connected to the outer side of the slide plate 51. A water inlet hose 53 and an air inlet hose 54 are fixedly connected to the bottom end of the slide plate 51. A switch hole 55 is opened on the inner side of the slide plate 51. A solenoid valve 56 is fixedly connected to the inner side of the switch hole 55. A double through hole 57 is opened on the inner side of the slide plate 51. The bottom end of the vertical plate 41 is fixedly connected to the top end of the slide plate 51. The top end of the electric telescopic rod 35 is fixedly connected to the bottom end of the slide plate 51.

[0032] As a further implementation of this solution, a limit telescopic rod 6 is fixedly connected to the inner side of the lower mold shell 31, and a hydraulic rod 2 is fixedly connected to the inner side of the lower mold shell 31. There are two hydraulic rods 2, and hydraulic rods 2 are installed at diagonal positions inside the lower mold shell 31. Through the above settings, the stability of the upper mold 1 when it moves can be improved, thereby improving the quality of zinc alloy forming.

[0033] As a further implementation of this scheme, the square groove 33 is connected to the column groove 34. The square groove 33 is rectangular in shape. The bottom end of the heat-conducting copper plate 36 is flush with the bottom end of the square groove 33. There are multiple heat-conducting copper plates 36, and there is a gap between the multiple heat-conducting copper plates 36. The vertical plate 41 is inserted into the gap between the heat-conducting copper plates 36. The outer side of the vertical plate 41 is in clearance fit with the outer side of the heat-conducting copper plate 36. The top end of the slide plate 51 is attached to the bottom end of the heat-conducting copper plate 36. The top end of the vertical plate 41 is attached to the bottom end of the lower mold base 32. Through the above arrangement, the heat-conducting copper plate 36 plays the role of absorbing and conducting heat to the lower mold base 32, improving the cooling efficiency of the lower mold base 32. At the same time, the heat-conducting copper plate 36 and the vertical plate 41 can support the lower mold base 32 to prevent the lower mold base 32 from deforming during the zinc alloy forming process.

[0034] As a further implementation of this solution, the groove 34 is cylindrical, the slide plate 51 is cylindrical, the outer side of the slide plate 51 fits against the inner side of the groove 34 in the lower mold shell 31, the outer side of the rubber ring 52 fits tightly against the inner side of the groove 34 in the lower mold shell 31, the center of the electric telescopic rod 35 is on the same vertical line as the center of the slide plate 51, and the diameter of the slide plate 51 is the same as the diameter of the groove 34. With the above settings, the cooling component 4 and the conveying component 5 can be moved as a whole by the electric telescopic rod 35, so that the vertical plate 41 can support the heat-conducting copper plate 36, the lower mold base 32 and the vertical plate 41. At the same time, the cooling component 4 can be stored inside the groove 34 to prepare for the cooling of the mold.

[0035] As a further implementation of this solution, the first through hole 42 penetrates the inner side of the vertical plate 41 from front to back, the second through hole 43 communicates with the first through hole 42, and the third through hole 44 penetrates the lower end of the vertical plate 41. Multiple first through holes 42 are provided. The third through hole 44 in the vertical plate 41 communicates with the through-hole 55. The through-hole 55 penetrates the inner side of the sliding plate 51 vertically. The inner side of the water inlet hose 53 is connected to the water inlet hose 53. There are two through-holes 55, which are connected through a double through hole 57. The inner side of the air inlet hose 54 is connected to the rear end. The through holes 55 are connected, and the number of through holes 55 is the same as the number of the third through holes 44. The lower mold shell 31 has mounting holes on the inner side near the water inlet hose 53 and the air inlet hose 54. The water inlet hose 53 and the air inlet hose 54 are both inserted into the mounting holes of the lower mold shell 31. Through the above settings, the effect of forming molten zinc alloy is achieved. This cooling method can gradually reduce the temperature of the mold and the molten zinc alloy, which can effectively prevent cracking of thinner parts of the mold caused by rapid cooling and improve the service life of the mold.

[0036] Workflow: During aluminum alloy production, molten zinc alloy is injected into the lower mold base 32. At this time, the top of the vertical plate 41 is in close contact with the bottom of the lower mold base 32, and the bottom of the heat-conducting copper plate 36 is in close contact with the top of the slide plate 51. This arrangement provides support for the lower mold base 32 during the forming of the molten zinc alloy, preventing deformation. When the hydraulic rod 2 is activated, it moves the upper mold 1 downward, and the limiting telescopic rod 6 retracts. The upper mold 1 forms the aluminum alloy, while the molten zinc alloy inside the lower mold base 32 undergoes initial forming. During cooling, the air inlet hose 54 is connected to the air outlet of the fan, and the water inlet hose 53 is connected to the water outlet of the cooling water pump. Activating the electric telescopic rod 35 moves the conveying assembly 5 and the cooling assembly 4 downwards as a whole. The sliding plate 51 slides inside the column groove 34, sliding out through the gaps between the multiple heat-conducting copper plates 36. After the cooling assembly 4 is retracted into the column groove 34, the existing fan delivers external cold air to the on / off hole 55 opened in the sliding plate 51. At this time, the rear solenoid valve 56 is open, and the front solenoid valve 56 is closed, allowing cold air to flow from the on / off hole. 55 and the double through-hole 57 enter the third through-hole 44, the second through-hole 43, and the first through-hole 42, and then flow out from the first through-hole 42. The outflowing cold air blows onto the heat-conducting copper plate 36, which plays the role of conducting and absorbing heat from the lower mold base 32. The air flows out from the through-hole near the left end of the square groove 33. At this time, the molten zinc alloy inside the lower mold base 32 is initially cooled. After cooling for a certain period of time, the rear solenoid valve 56 is closed and the front solenoid valve 56 is opened, and water is delivered into the water inlet hose 53 by the existing water pump. Following the same principle, water flows out from the first through hole 42 and enters the interior of the square groove 33 and the upper part of the sliding plate 51. Through the seal of the rubber ring 52, water can be prevented from contacting the electric telescopic rod 35, and then flows out from the through hole at the left end of the square groove 33. This process achieves the effect of cooling the heat-conducting copper plate 36 and the lower mold base 32, and achieves the effect of forming the molten zinc alloy. This cooling method can gradually reduce the temperature of the mold and the molten zinc alloy, which can effectively prevent cracking of thinner parts of the mold caused by rapid cooling and improve the service life of the mold.

[0037] 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.
