Grinding device for casting mold production

Abstract

The invention relates to the technical field of mold machining equipment, in particular to a grinding device for casting mold production. The grinding device comprises a shell, a motor is fixedly mounted at one side of the shell, a rotating shaft is fixedly connected to the output shaft end of the motor, and a connecting block is fixedly connected to the middle of the rotating shaft. According to the grinding device for casting mold production, through the arrangement of an annular cavity, a guide pipe, a connecting block and supporting blocks, when a left-side grinding belt is in a high-temperature state after long-time grinding, the left-side supporting block does not make contact with a driving roller any more, the left-side driving roller stops rotating, and the situation that the overheated left-side grinding belt continues to conduct grinding work can be avoided; and meanwhile, the supporting block in a right-side cavity makes contact with a right-side driving roller to drive a right-side grinding belt to continue to grind a workpiece, similarly, when the right-side grinding belt is at high temperature, the left-side grinding belt can be switched to continue grinding work, and therefore the alternate grinding effect is achieved, the loss of the device can be reduced, the service life of abrasive paper is prolonged, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mold processing equipment, in particular to a grinding device for casting mold production. Background technique [0002] Mold polishing generally uses oil stone, sandpaper, polishing paste, wool wheel, etc. to polish the cavity surface of the mold so that the working surface of the mold can be as bright as a mirror. It is called mold grinding. During the mold casting process, the casting is completed The final mold needs to be polished with burrs and polished on the surface of the mold. There are two purposes for mold grinding and polishing; It is easy to demould, so that the plastic is not stuck on the mold and cannot be taken off, so that the mold can fit better. Burrs refer to extremely fine microscopic metal particles on the surface of the workpiece. They are formed during cutting, grinding, milling and other Similar to chips formed during machining, if the burrs on the surface of the workpiece are n...

[0002] Mold polishing generally uses oil stone, sandpaper, polishing paste, wool wheel, etc. to polish the cavity surface of the mold so that the working surface of the mold can be as bright as a mirror. It is called mold grinding. During the mold casting process, the casting is completed The finished mold needs to be polished with burrs and polished on the surface of the mold. There are two purposes for mold grinding and polishing; It is easy to demould, so that the plastic is not stuck on the mold and cannot be taken off, so that the mold can fit better. Burrs refer to extremely fine microscopic metal particles on the surface of the workpiece. They are formed during cutting, grinding, milling and other If the burrs on the surface of the workpiece are not removed during the processing of similar chips, it will not only affect the precision of the product, but also the workers will be easily scratched during operation

[0003] However, the current mold grinding device still has the following deficiencies in the continuous processing process: most of them quickly dissipate heat from the processing position through additional heat dissipation components such as fans, so that the temperature of the processing position is controlled, thereby avoiding high-temperature wear of the sandpaper. During the processing, the heat dissipation cannot keep up with the processing in a timely and effective manner, resulting in the sandpaper still being processed at high temperature for a long time, which seriously affects the life of the sandpaper, increases the loss of the device, and the heat dissipation after shutdown seriously increases the cost, and the frequent replacement of sandpaper and other losses Parts also reduce processing efficiency and increase costs, so there is an urgent need for a low-loss alternative grinding device
