Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy front cover die-casting, in particular to a die-casting mold for an automobile aluminum alloy front cover. Background Art

[0002] Die casting is a metal casting process characterized by the use of high pressure to apply molten metal to the mold cavity. The mold is usually made of a higher strength alloy. This process is somewhat similar to injection molding. Most die-cast castings do not contain iron, such as zinc, copper, aluminum, magnesium, lead, tin, lead-tin alloys, and their alloys. The front cover of a car is generally produced by a die-casting process because the die-casting mold is an indispensable operating tool. However, there are still some problems in the use of existing die-casting molds. For example, a technical solution is disclosed in Patent No.: CN202222190574.2. This technical solution mentions that after the material is die-casted, the material temperature is too high, resulting in the material being unable to be quickly removed. Therefore, after the die-casting is completed, the equipment uses liquid to cool the material and then facilitate its removal. However, in actual use, after the liquid is sprayed on the surface of the material, it cannot completely evaporate, causing the liquid to flow into the mold. Once the material enters the mold, if it cannot be cleaned in time, the subsequent die-casting quality will be affected. At the same time, each manual cleaning will affect the working efficiency of the equipment, thereby reducing the practicality and convenience of the equipment.

[0003] Based on this, the utility model designs a die-casting mold for an automobile aluminum alloy front cover to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a die-casting mold for an automobile aluminum alloy front cover, so as to solve the problem that the mold is easily affected when the equipment proposed in the above background technology is used, thereby affecting the die-casting quality.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A die-casting mold for an automobile aluminum alloy front cover comprises a base plate, a mold is mounted on the base plate, a moving mechanism is mounted on the base plate, a driving mechanism is mounted on the base plate, the driving mechanism and the moving mechanism are movably engaged, two moving seats are threadedly connected to the moving mechanism, a rotating shaft is rotatably connected between the two moving seats, two one-way wheels are mounted on the rotating shaft, two racks are fixedly connected to the base plate, the one-way wheels and the racks are movably engaged, a rotating seat is mounted on the rotating shaft, a cooling mechanism is mounted on the rotating seat, and an adsorption mechanism is provided on the rotating seat.

[0007] Preferably, the moving mechanism includes a fixed plate, a threaded rod, a first torsion spring, a first rotating column and a full gear. Two groups of fixed plates are installed on the base plate. A threaded rod is rotatably connected between the two fixed plates. The two threaded rods are transmission-connected. One of the threaded rods is provided with a first torsion spring. The base plate is rotatably connected with a first rotating column. The first rotating column is transmission-connected to one of the threaded rods, and a full gear is installed on the first rotating column.

[0008] Preferably, the driving mechanism includes a driving motor and a half gear. The driving motor is installed on the base plate, and the output end of the driving motor is installed with a half gear. The half gear is meshed and connected with the moving mechanism.

[0009] Preferably, the cooling mechanism includes a water tank, a nozzle, a second rotating column, a second torsion spring and a water-absorbing sponge. The water tank is installed on the rotating seat, and a plurality of nozzles are provided on the water tank. The rotating seat is rotatably connected to the second rotating column, and the second rotating column is installed with a second torsion spring and a water-absorbing sponge.

[0010] Preferably, the adsorption mechanism includes a bellows, a suction cup and a negative pressure machine, the bellows is installed on the rotating seat, the suction cup is installed on the bellows, and the negative pressure machine is installed on one side of the bellows.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model puts the molten solution into the mold so that the solution is die-cast in the mold. After the material is die-cast, the drive motor is controlled to work. When the drive motor drives the half gear to rotate, the half gear drives the full gear to rotate. At this time, the first rotating column controls the rotation of the threaded rod. When the threaded rod rotates, the first torsion spring is compressed. At the same time, the movable seat threadedly connected to the threaded rod moves. When the movable seat moves, the nozzle sprays the liquid in the water tank to act on the die-cast material. At this time, the die-cast material is cooled by the liquid, which facilitates the removal of the material. When the movable seat moves, the torsion of the second torsion spring acts on the second rotating column. At this time, the absorbent sponge can pass through the position after the nozzle is sprayed, and then it can absorb excess liquid, thereby avoiding too much liquid, causing the liquid to enter the mold, thereby affecting the subsequent die-casting quality of the equipment.

[0013] 2. When the one-way wheel moves to the rack position, the half gear and the full gear disengage. At this time, the first torsion spring is reset, causing the threaded rod to rotate in the opposite direction. At this time, the one-way wheel controls the rotation seat to rotate under the drive of the rack, so that the suction cup rotates to the upper side of the die-casting material, and the cooling mechanism is away from the material. At this time, the negative pressure machine generates air pressure and adsorbs the material through the suction cup. At the same time, with the movement of the threaded rod, the material can be adsorbed and away from the mold, and then the material is taken out. This reduces the manual material taking when the equipment is in use, makes it more convenient to take out the material, and further improves the processing efficiency of the equipment.

The first rotating column 6 is installed with a full gear 7; it is convenient to control the movement of the cooling mechanism 16 and the adsorption mechanism 22, thereby facilitating the cooling and material removal of the material.

[0025] Among them, the driving mechanism 8 includes a driving motor 9 and a half gear 10. The driving motor 9 is installed on the base plate 1, and the half gear 10 is installed at the output end of the driving motor 9. The half gear 10 is meshed and connected with the moving mechanism 2; it is convenient to control the movement of the moving mechanism 2, thereby completing the cooling and material removal of the material, making the equipment more convenient when used.

[0026] Among them, the cooling mechanism 16 includes a water tank 17, a nozzle 18, a second rotating column 19, a second torsion spring 20 and a water-absorbing sponge 21. The water tank 17 is installed on the rotating seat 15, and multiple nozzles 18 are provided on the water tank 17. The second rotating column 19 is rotatably connected to the rotating seat 15, and the second rotating column 19 is installed with a second torsion spring 20 and a water-absorbing sponge 21; it is convenient to cool the material while preventing liquid from entering the mold 26, thereby affecting the quality of the product.

[0028] Working principle:

[0029] During operation, the molten solution is put into the mold 26 so that the solution is die-cast in the mold 26. After the material is die-cast, the drive motor 9 is controlled to work. When the drive motor 9 drives the half gear 10 to rotate, the half gear 10 drives the full gear 7 to rotate. At this time, the first rotating column 6 controls the threaded rod 4 to rotate. When the threaded rod 4 rotates, the first torsion spring 5 is compressed. At the same time, the movable seat 11 threadedly connected to the threaded rod 4 moves. When the movable seat 11 moves, the nozzle 18 sprays the liquid in the water tank 17 to act on the die-cast material. At this time, the die-cast material is cooled by the liquid, which facilitates the removal of the material. When the movable seat 11 moves, the torsion of the second torsion spring 20 acts on the second rotating column 19. At this time, the absorbent sponge 21 can pass through the position after the nozzle 18 sprays, and then it can absorb excess liquid, thereby avoiding too much liquid, causing the liquid to enter the mold 26, thereby affecting the equipment. The subsequent die-casting quality is improved. When the one-way wheel 13 moves to the position of the rack 14, the half gear 10 and the full gear 7 are disengaged. At this time, the first torsion spring 5 is reset, causing the threaded rod 4 to rotate in the opposite direction. At this time, the one-way wheel 13 controls the rotating seat 15 to rotate under the drive of the rack 14, so that the suction cup 24 is rotated to the upper side of the die-casting material, and the cooling mechanism 16 is away from the material. At this time, the negative pressure machine 25 generates air pressure and adsorbs the material through the suction cup 24. At the same time, with the movement of the threaded rod 4, the material can be adsorbed and away from the mold 26, and then the material is taken out, which reduces the manual material taking when the equipment is in use, makes it more convenient to take out the material, and further improves the processing efficiency of the equipment. The positions of the two racks 14 are located on both sides of the moving mechanism 2. The repeated cycle of the moving mechanism 2 can ensure the repeated rotation of the rotating seat 15, and then adjust the position of the cooling mechanism 16 and the adsorption mechanism 22, so as to ensure the continuous operation of the equipment.
