[0002] As we all know, zinc alloy is an alloy composed of zinc and other elements. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium, etc. Zinc alloy has a low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, and waste materials are easy to recycle and remelt, but the creep strength is low and it is easy to cause dimensional changes due to natural aging.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] Reference Figure 1-5 A zinc alloy die-casting machine with a cooling mechanism comprises a hollow disk 1, an upper side wall of the hollow disk 1 is fixedly connected to a die base 2, a side wall of the hollow disk 1 is fixedly connected to a hydraulic cylinder 4 located above the die base 2 through an inverted C-shaped plate 3, a driving end of the hydraulic cylinder 4 is vertically downward and fixedly connected to a die core 6 through a lifting plate 5, and a die groove 7 matching the die core 6 is formed on the upper side wall of the die base 2. When in use, the raw material is placed in the die groove 7, and then the hydraulic cylinder 4 is started to drive the lifting plate 5 to move downward, so that the die core 6 starts to die-cast the raw material.

[0027] An airflow cavity is provided in the mold core 6, and a plurality of airflow holes 8 are provided on the inner wall of the airflow cavity at equal intervals. An inner toothed ring 9 is movably sleeved on the outer wall of the hollow disk 1, and the inner wall of the inner toothed ring 9 is fixedly connected with two support rings movably embedded on the outer wall of the hollow disk 1, which play a supporting and limiting effect on the inner toothed ring 9. A motor 10 is fixedly connected to the inner bottom wall of the hollow disk 1, and the output shaft end of the motor 10 is vertically upward and fixedly connected with a gear 11 that penetrates the inner wall of the hollow disk 1 and meshes with the inner toothed ring 9. A hollow blast plate 12 is fixedly connected to the upper side wall of the inner toothed ring 9, and a plurality of blast holes 13 are provided on the side wall of the hollow blast plate 12 close to the mold base 2, and a filter tube 14 is connected to the side of the hollow blast plate 12 away from the blast holes 13. The filter tube 14 is connected to the air cooler 16 through the transition tube 15. When the die casting is completed, the motor 10 is started to drive the gear 11 to rotate, so that the inner gear ring 9 meshing therewith rotates, thereby driving the hollow blast plate 12 to move in a circular motion around the mold base 2. At this time, the air cooler 16 is also started synchronously, and cold air is blown into the hollow blast plate 12 through the transition tube 15 and the filter tube 14, and sprayed toward the mold base 2 from each blast hole 13. The circular motion of the air cooler 16 can realize the all-round cooling of the mold base 2 by the hollow blast plate 12. At the same time, during the circular motion, the cold air can also pass through the corresponding air flow hole 8 into the air flow cavity to flow and cool the mold groove 7, thereby improving the cooling effect on the parts.

[0028] Each air flow hole 8 is provided with a heat dissipation mechanism, which includes a sealing plate 28 that is slidably fitted in the air flow hole 8, a side wall of the sealing plate 28 is connected to a telescopic rod 29 that is fixedly connected to the air flow cavity, a spring three 30 is connected between the telescopic rod 29 and the sealing plate 28, and an outer wall of the sealing plate 28 is fixedly connected to two heat conducting blocks 31 through two support rods. When the cold air enters the air flow hole 8, it pushes the sealing plate 28 to move inward, causing the telescopic rod 29 to contract and compress the spring three 30 until the heat conducting block 31 contacts the inner wall of the air flow cavity on one side close to the mold groove 7, conducts the heat to the heat conducting block 31, and then the cold air flows into the next air flow hole 8, and the air flow hole 8 Under the action of spring three 30, the heat-conducting block 31 inside will move outward until it is separated from the inner wall of the airflow cavity, and then the airflow entering the next airflow hole 8 will flow in the airflow cavity to cool the heat-conducting block 31 in the previous airflow hole 8, thereby realizing the reciprocating contact and collision between each heat-conducting block 31 and the inner wall of the airflow cavity, which can continuously discharge the heat in the mold groove 7, and cooperate with the flow of cold air in the airflow cavity, which greatly improves the cooling effect of the parts. At the same time, through the knocking of each heat-conducting block 31 on the inner wall of the airflow cavity, the inner wall of the mold groove 7 can vibrate, so that the parts and the inner wall of the mold groove 7 and the mold core 6 are loose, which is conducive to the demolding of the parts.

[0029] The upper side wall of the inner gear ring 9 is fixedly connected with a hollow dust collecting plate 26 which is located opposite to the hollow blast plate 12. A plurality of dust collecting holes are provided on the left side of the hollow dust collecting plate 26. The hollow dust collecting plate 26 and the input port of the air cooler 16 are connected with an air flow pipe 27. When the air cooler 16 blows air to the mold base 2 through the hollow blast plate 12, the air flow pipe 27 can also be used to absorb the blown dust through each dust collecting hole of the hollow dust collecting plate 26 to avoid dust flying.

[0030] A filter plate 32 is provided in the filter tube 14, and the lower side wall of the filter tube 14 is connected to a dust exhaust pipe 38 located on the left side of the filter plate 32. An electromagnetic valve is provided on the dust exhaust pipe 38. The filter plate 32 can filter impurities in the gas entering the filter tube 14. After cooling is completed, the electromagnetic valve can be opened to discharge the filtered impurities through the dust exhaust pipe 38.

[0031] Two vibration anti-blocking mechanisms are provided on the left side of the filter plate 32, and the vibration anti-blocking mechanisms include a moving rod 33 slidably inserted on the side wall of the filter plate 32, and the two ends of the moving rod 33 are respectively fixedly connected with a baffle 36 and a sealing ball 34 slidably fitted on the inner wall of the transition pipe 15, and a spring four 37 is connected between the baffle 36 and the filter plate 32. The outer wall of the moving rod 33 is embedded with a plurality of magnetic blocks 35, and both sides of the moving rod 33 are provided with a swing rod 39 rotatably connected to the filter tube 14, and the opposite ends of the two swing rods 39 are fixedly connected with a magnetic block 2 40 with an opposite magnetic pole to the magnetic block 1 35, and two springs 5 ​​41 are connected between each swing rod 39 and the filter plate 32, and the side wall of each swing rod 39 is fixedly connected with two The vibrating ball 42 and the air cooler 16 can push the sealing ball 34 to move right when blowing air, and drive the moving rod 33 and the baffle 36 to move right to stretch the spring four 37. When the magnetic block 1 35 and the magnetic block 2 40 are opposite to each other, the adsorption force between the two can drive the swing rod 39 to rotate, and compress and stretch the corresponding spring four 37, until the vibrating ball 42 close to the moving rod 33 hits the surface of the filter plate 32. When the magnetic block 1 35 is away from the magnetic block 2 40, the swing rod 39 will rotate and reset under the action of the spring four 37. Therefore, under the adsorption of multiple magnetic blocks 1 35 and the magnetic block 2 40 in turn, the vibrating ball 42 can continuously hit the filter plate 32, causing it to vibrate, and shake off the impurities on the surface of the filter plate 32 to avoid clogging.

[0032] A lifting plate 17 is provided at the bottom of the die groove 7, and a lifting rod 21 penetrating the upper side wall of the hollow disk 1 is fixedly connected to the lower side wall of the lifting plate 5, and an automatic lifting mechanism is provided between the lifting rod 21 and the lifting plate 17. The automatic lifting mechanism includes two movable rods 18 fixedly connected to the lower side wall of the lifting plate 17 and slidably inserted at the bottom of the die groove 7, and the two movable rods 18 are commonly connected with a positioning plate 1 20, and a spring 19 is commonly connected between the positioning plate 1 20 and the inner top wall of the hollow disk 1, and the lower end of the lifting rod 21 is fixedly connected with a positioning plate 22, and a groove 2 and a groove 1 are respectively provided on the side wall opposite to the positioning plate 1 22, and an electromagnet 24 is fixedly connected in the groove 1, and an iron rod 23 is connected in the groove 2 through a spring 25. When the lifting plate 5 moves downward, the positioning plate 22 can be driven by the lifting rod 21 to move down to be flush with the positioning plate 1 20. Then when the motor 10 is started, the electromagnet 24 is energized to adsorb the iron rod 23 until it is clamped in the groove two and the spring two 25 is stretched, thereby realizing the connection and fixation of the positioning plate one 20 and the positioning plate two 22. After the die casting is completed and cooled for a period of time, the hydraulic cylinder 4 drives the lifting plate 5 to move up and can drive the positioning plate one 20 and the positioning plate two 22 to move up synchronously through the lifting rod 21, and use the two movable rods 18 to drive the lifting plate 17 to move up and push the parts out of the die groove 7, so as to realize the automatic lifting of the parts, facilitate the removal of the parts, and have a high degree of automation. At the same time, the spring one 19 is compressed and the parts are cooled for a while. After the cooling is completed, the motor 10 is turned off and the electromagnet 24 is powered off. Under the action of the spring two 25, the iron rod 23 moves to the left and resets to disengage from the groove two, so that the positioning plate one 20 moves downward under the action of the spring one 19, so that the lifting plate 17 returns to the initial position.

[0033] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
