Description

Technical Field

[0001] This utility model relates to the technical field of casting production and maintenance equipment, specifically to an internal cavity grinding device for centrifugal casting molds. Background Technology

[0002] Centrifugal casting molds are molding tools that use centrifugal force to uniformly adhere liquid materials (such as resin or metal) to the inner wall of a rotating mold, which then solidifies upon cooling or chemical reaction, ultimately producing tubular or hollow cylindrical products. The principle is that the high-speed rotation of the mold generates centrifugal force, causing the material to spread and solidify evenly. This process is particularly suitable for producing hollow products, offering advantages such as low internal stress, high surface finish, and good structural strength. Grinding the inner cavity of the mold is a core step in ensuring molding quality. Grinding eliminates surface defects such as tool marks and oxide layers left from machining and heat treatment processes, significantly improving the smoothness of the inner cavity. Cleanliness and dimensional accuracy are important considerations. Fine grinding can reduce the flow resistance of molten material in the mold, reduce friction during product demolding, and delay mold wear. At the same time, it enhances the fit of the parting surface, avoids overflow during injection molding, and ensures product accuracy. In addition, optimizing surface roughness can reduce stress concentration and microcracks during mold use, thereby extending mold life and improving production efficiency. However, for molds of different sizes, it is necessary to balance grinding compatibility and processing efficiency through process optimization. Existing technologies may already have solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: an internal cavity grinding device for centrifugal casting molds, comprising: a device base, a cooperating base, and a propulsion power housing, wherein the propulsion power housing is installed on the device base, an insert-type grinding structure is installed on the cooperating base, and a load-bearing drive structure is installed on the device base, wherein the load-bearing drive structure comprises: a propulsion power motor, a propulsion screw, a covering propulsion sleeve, a connecting propulsion column, a supporting side column, a top support plate, an electric slide rail, a pair of electric sliders, several hydraulic telescopic rods, several semi-arc support blocks, several covering transfer wheels, a centrifugal casting mold body, a secondary extension track, a spin-moving housing, a spin-power motor, a spin-transmission shaft, a split gearbox, and a pair of drive rubber wheels; The propulsion motor is installed inside the propulsion housing. The propulsion screw is inserted into the covering propulsion sleeve. The connecting propulsion column is movably inserted into the device base and connected to the covering propulsion sleeve. The propulsion screw is connected to the propulsion motor. The support side column is installed on the connecting propulsion column and connected to the top support plate. The electric slide rail is installed on the top support plate. A pair of electric sliders are respectively installed on the electric slide rail. A pair of hydraulic telescopic rods are respectively installed on a pair of electric sliders and installed on the connecting propulsion column. Several semi-circular support blocks are respectively installed on several hydraulic... On the telescopic rod, several covered transfer wheels are respectively mounted on several semi-arc support blocks via rotating shafts. The centrifugal casting mold body is movably connected to several covered transfer wheels. The secondary extension track is mounted on the device base. The spin-moving outer shell is mounted on the secondary extension track. The spin-power motor is mounted inside the spin-moving outer shell. The spin-drive rotating shaft is connected to the spin-power motor. The transfer gearbox is mounted on the spin-moving outer shell and is connected to the hydraulic telescopic rod. A pair of drive rubber wheels are respectively connected to the transfer gearbox via rotating shafts. A pair of drive rubber wheels are movably connected to the centrifugal casting mold body. It should be noted that, as described above, the centrifugal casting mold body is placed on the device base, so that multiple covered transfer wheels and multiple drive rubber wheels on the device base come into contact with the surface of the centrifugal casting mold body. This drives the electric slide rail on the top support plate, thereby causing a pair of electric sliders to move to a designated position, driving three hydraulic telescopic rods to extend, thus causing three semi-circular support blocks to fully adhere to the outer surface of the centrifugal casting mold body. This ensures that the multiple covered transfer wheels are in close contact with the centrifugal casting mold body. Subsequently, the spin drive motor inside the spin moving shell is driven to rotate, thereby causing the spin drive shaft to rotate, which in turn drives the distribution gearbox to rotate, causing the shaft to rotate and driving the pair of drive rubber wheels to rotate. The rotating drive rubber wheel then rotates the centrifugal casting mold body, causing it to spin stably on the device base using multiple covered transfer wheels. Simultaneously, the propulsion motor inside the propulsion housing operates, causing the propulsion screw to rotate. Because the covered propulsion sleeve has coupling threads, it is pushed towards the connecting propulsion column, causing the connecting propulsion column to move outwards. Under the pressure of gravity from the centrifugal casting mold body, the spinning transfer shell slides on the secondary extension track. In summary, the centrifugal casting mold body, under the operation of the propulsion motor, slowly moves towards the connecting propulsion column while maintaining its spinning state.

[0004] Preferably, the insert-type grinding structure includes: several cooperating facility hubs, cooperating covering shells, cooperating counterweights, interlocking through columns, through column positioning magnetic blocks, base connecting positioning electromagnets, electrically adjustable telescopic rods, and diamond grinding heads. Several of the aforementioned collaborative facility hubs are respectively installed on the collaborative base, the collaborative covering shell is installed on the collaborative base, the collaborative counterweight is installed on the collaborative covering shell, the through-post is installed on the collaborative covering shell, the through-post positioning magnet is installed on the through-post, the base connecting positioning electromagnet is installed on the device base, the electric adjusting telescopic rod is installed on the through-post, the diamond grinding head is installed on the electric adjusting telescopic rod, and the diamond grinding head is connected to the centrifugal casting mold body, and the through-post is inserted into the centrifugal casting mold body; It should be noted that, as described above, the through-pipe is inserted into the centrifugal casting mold body, driving the electric adjusting telescopic rod to extend, thereby making the diamond grinding head fit into the inner cavity of the centrifugal casting mold body. At the same time, the positioning magnetic block of the through-pipe and the positioning electromagnet of the base attract and connect for alignment. Then, the stop buckle set on the hub of the coordinating facility is fixed and locked in place. The coordinating counterweight block plays a counterweight role, and the coordinating shell plays a counterweight connection role. After the diamond grinding head is tightly attached to the inside of the centrifugal casting mold body, the centrifugal casting mold body gradually rotates and shifts under the rotation of the propulsion motor, thereby allowing the diamond grinding head to perform a comprehensive grinding treatment on the inner cavity of the centrifugal casting mold body.

[0005] Preferably, the propulsion power housing is provided with a maintenance and inspection port; Preferably, the collaborative covering shell is provided with a counterweight maintenance port; Preferably, the hub of the coordinating facility is provided with a stop buckle; Preferably, the encapsulated propulsion sleeve is provided with a coupling thread.
