Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a cooling device for investment casting. Background Art

[0002] Investment casting is also called lost wax casting, which includes the processes of pressing wax, trimming wax, forming trees, dipping slurry, melting wax, pouring molten metal and post-processing. Lost wax casting is to use wax to make a wax mold of the part to be cast, and then apply mud on the wax mold, which is the mud mold. After the mud mold is dried, put it into hot water to melt the wax mold inside. Take out the mud mold with melted wax mold and bake it into a ceramic mold. Once baked. Generally, a pouring port is left when making the mud mold, and then the molten metal is poured from the pouring port. After cooling, the required parts are made.

[0003] When cooling the casting, the existing investment casting cooling device has a slow cooling speed and a long solidification time, which easily leads to pinhole defects in certain parts of the casting, reducing the applicability of the device. Summary of the invention

[0007] The utility model creatively arranges a bottom plate, a top plate, a screw, a guide rod, a movable plate, a cooling fan and a placement plate. First, a main motor is started to drive the screw to rotate, thereby driving the movable plate to move downward, and then the casting is placed on the placement plate. The main motor is started again to drive the screw to rotate and drive the movable plate to move upward until it is close to the air outlet duct of the cooling fan. At this time, the driving component is started to drive the placement plate to rotate, and the cooling fan is started at the same time to air-cool the casting on the placement plate. Since the casting on the placement plate is cooled during the rotation process, the casting can be cooled more comprehensively and evenly, the cooling speed is improved, the solidification time is reduced, it is not easy to cause pinhole defects in certain parts of the casting, and the applicability of the device is improved.

[0008] Since the distance between the casting and the air outlet pipe can be adjusted, not only is the operation more convenient, but it can also adapt to castings of different heights for air cooling, further improving the applicability of the device.

The support frame is fixedly connected to the bottom of the movable plate, and the linkage motor is fixedly installed on the support frame. The pulley one and the pulley two are both rotatably connected between the movable plate and the support frame. The output shaft of the linkage motor is connected to pulley one, and a belt is wound between pulley one and pulley two.

[0010] The linkage motor drives the pulley 1 to rotate. Since a belt is wound between the pulley 1 and the pulley 2, the pulley 2 rotates synchronously in the same direction as the pulley 1.

[0011] In the above-mentioned investment casting cooling device, the placement plate is circular in shape and has a concave placement groove.

[0012] The casting is placed in the placement tank.

[0013] In the above-mentioned investment casting cooling device, the number of the placing plates is two, one of which is fixedly connected to the first pulley, and the other is fixedly connected to the second pulley.

[0014] The arrangement of two placing trays increases the number of castings that can be placed.

[0015] In the above-mentioned investment casting cooling device, the number of the air outlet pipes is several, and the several air outlet pipes are evenly arranged at the bottom of the cooling fan and directly opposite to the moving plate.

[0017] In the above-mentioned investment casting cooling device, the clamping assembly includes a fixed block and a clamping block, the fixed block is fixedly connected to the placement plate, the side of the fixed block has a groove, a spring is fixedly connected in the groove, the clamping block and the spring are connected, the fixed block, the spring and the clamping block form a positioning unit, the number of the positioning units is two, the two positioning units are arranged opposite to each other and the two positioning units constitute a clamping assembly.

[0018] The casting is placed between two clamping blocks. Under the elastic force of the spring, the clamping blocks always have an inward force, so that the two positioning units can clamp and position the casting on the dewaxing plate to prevent the casting from tipping over.

[0019] In the above-mentioned investment casting cooling device, the number of the clamping assemblies is several, and the several clamping assemblies are evenly distributed circumferentially with the center of the placement disk as the center.

[0020] Several clamping assemblies can clamp multiple castings simultaneously.

[0021] Compared with the prior art, the present investment casting cooling device creatively arranges a bottom plate, a top plate, a screw, a guide rod, a movable plate, a cooling fan and a placement plate. First, the main motor is started to drive the screw to rotate, thereby driving the movable plate to move downward, and then the casting is placed on the placement plate. The main motor is started again to drive the screw to rotate and drive the movable plate to move upward until it is close to the air outlet duct of the cooling fan. At this time, the drive assembly is started to drive the placement plate to rotate, and the cooling fan is started at the same time to air-cool the casting on the placement plate. Since the casting on the placement plate is cooled during the rotation process, the casting can be cooled more comprehensively and evenly, the cooling speed is improved, the solidification time is reduced, and it is not easy to cause pinhole defects in certain parts of the casting, thereby improving the applicability of the device.

[0022] Since the distance between the casting and the air outlet pipe can be adjusted, not only is the operation more convenient, but it can also adapt to castings of different heights for air cooling, further improving the applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
