Description
Technical Field
[0001] This utility model belongs to the technical field of coating mixers, and particularly relates to a coating mixer for lost foam casting. Background Technology
[0002] When using lost foam casting to produce aluminum alloy products, a fire-retardant coating needs to be applied to the surface of the foam plastic model. The fire-retardant coating can improve the strength and rigidity of the foam plastic model. During pouring, the fire-retardant coating separates the molten metal from the mold, resulting in a casting with a smooth surface and no sand adhering. At the same time, it can prevent dry sand from entering the mold, causing mold collapse, and prevent defects such as porosity and carbon black. Therefore, the fire-retardant coating plays a very important role in lost foam casting.
[0003] In the prior art, utility model patent CN204469648U discloses a defoaming mixer for fire-retardant coatings used in lost foam casting. It includes two connected sets of first and second mixing devices. Both the first and second mixing devices are equipped with mixing containers and electric stirring paddles. A circulation pump is provided between the first and second mixing devices to draw the fire-retardant coating from the bottom of the mixing container of the first mixing device to the mixing container of the second mixing device. A return trough is provided at the top of the mixing container of the second mixing device to return the surface layer of fire-retardant coating to the mixing container of the first mixing device. A fire-retardant coating inlet is located near the electric stirring paddle in the mixing container of the second mixing device. This utility model, by setting up two connected mixing devices, performs initial mixing in the first mixing device and then uses a circulation pump to further mix the fire-retardant coating in the second mixing device. The two mixing processes and the circulation pump ensure more uniform mixing and better defoaming of the fire-retardant coating.
[0004] In existing coating mixers for lost foam casting, the mixing tank is placed directly below the mixing assembly, making it prone to tipping over due to its own inertia during mixing. Therefore, we propose a new coating mixer for lost foam casting. Utility Model Content
[0005] The purpose of this invention is to provide a coating mixer for lost foam casting, which avoids the problem that the mixing tank is prone to tipping over due to its own inertia during mixing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A mixing cylinder is fitted to the outer wall of the installation block. The mixing assembly is located above the mixing cylinder and is used to mix the casting coating inside the mixing cylinder.
[0008] Preferably, the sliding block forms a horizontal sliding structure between the lifting slider adjusting support rod and the limiting slide groove. In this embodiment, the lifting slider drives the sliding block to slide along the groove of the limiting slide groove through the adjusting support rod, thereby realizing the sliding operation of the sliding block.
[0009] Preferably, the mounting block has an arc shape, and the mixing cylinder is fixed to the mounting assembly through the mounting block. In this embodiment, the sliding block drives the mounting block at one end of the connecting frame to fit tightly against the outer wall of the mixing cylinder, so as to prevent the mixing cylinder from shaking or even tipping over when the coating is being mixed.
[0010] Preferably, the stirring assembly includes a bracket; the outer wall of the mounting assembly is fixedly connected to the bracket, the bottom end of the bracket is fixedly connected to the base, the outer wall of the bracket is fixedly connected to a pneumatic push rod, the output end of the pneumatic push rod is fixedly connected to a lifting frame, a guide groove is provided at the connection between the bracket and the lifting frame, the top end of the lifting frame is fixedly connected to a stirring motor, the output end of the stirring motor is fixedly connected to a rotating shaft, the bottom end of the rotating shaft is fixedly connected to a stirring block, the outer wall of the stirring block is fixedly connected to a stirring rod, and one end of the stirring rod is fixedly connected to a stirring plate. In this embodiment, the pneumatic push rod drives the lifting frame to slide vertically along the guide groove, so that the stirring block below the lifting frame extends into the stirring cylinder. Then, the stirring motor drives the stirring block to rotate through the rotating shaft. The rotation of the stirring block drives the stirring rod and the stirring plate to rotate synchronously, thus fully stirring the lost foam casting coating.
[0011] Preferably, the bracket is triangular in shape and the base is U-shaped. In this embodiment, by setting the triangular bracket and the U-shaped base, the stability of the paint mixer can be improved.
[0012] Preferably, there are two sets of mounting blocks, which are symmetrical about the rotating shaft. The rotating shaft and the central axis of the stirring drum coincide. In this embodiment, the rotating shaft is prevented from colliding with the stirring drum during stirring.
[0013] Preferably, the stirring rods are provided in three sets, and the stirring plate is inclined. In this embodiment, the stirring motor drives the stirring block to rotate through the rotating shaft. The rotation of the stirring block drives the stirring rods and the stirring plate to rotate synchronously, so as to fully stir the lost foam casting coating.
[0014] Compared with the prior art, the beneficial effects of the coating mixer for lost foam casting described in this utility model are:
[0015] 1. An installation block is provided. Rotating the knob drives the lifting slider to slide vertically via a screw. The lifting slider drives the sliding block to slide along the groove of the limiting slide through the adjusting support rod. The sliding block causes the installation block at one end of the connecting frame to fit tightly against the outer wall of the mixing drum. The installation block is arc-shaped to prevent the mixing drum from shaking or even tipping over during the mixing of the coating.
[0016] 2. Equipped with a stirring rod and a stirring plate, the pneumatic push rod drives the lifting frame to slide vertically along the guide groove, causing the stirring block below the lifting frame to extend into the stirring drum. Then, the stirring motor drives the stirring block to rotate through the rotating shaft. The rotation of the stirring block drives the stirring rod and stirring plate to rotate synchronously, thus fully stirring the lost foam casting coating. Attached Figure Description

[0025] The stirring assembly is located above the stirring tank 10 and is used to stir the casting coating inside the stirring tank 10.
[0026] Based on the above structure, the rotation of knob 3 drives the lifting slider 4 to slide vertically through screw 2. The lifting slider 4 drives the sliding block 6 to slide along the groove of the limiting slide groove 7 through the adjusting support rod 5. The sliding block 6 drives the mounting block 9 at one end of the connecting frame 8 to fit tightly against the outer wall of the mixing drum 10, so as to prevent the mixing drum 10 from shaking or even tipping over when the coating is being mixed.
[0027] In one embodiment, the sliding block 6 is adjusted by the lifting slider 4 to form a horizontal sliding structure between the support rod 5 and the limiting groove 7. The lifting slider 4 drives the sliding block 6 to slide along the groove of the limiting groove 7 through the adjustment support rod 5, thereby realizing the sliding operation of the sliding block 6.
[0028] In one embodiment, the mounting block 9 is arc-shaped, and the mixing drum 10 is fixed to the mounting assembly 1 through the mounting block 9. The sliding block 6 slides to make the mounting block 9 at one end of the connecting frame 8 fit tightly against the outer wall of the mixing drum 10, preventing the mixing drum 10 from shaking or even tipping over during the mixing of the coating.
[0029] In one embodiment, the stirring assembly includes a bracket 11. The bracket 11 is fixedly connected to the outer wall of the mounting assembly 1.
