Description
Technical Field
[0001] The utility model relates to the technical field of sand box turning machines, in particular to a sand box turning machine with an active limiting mechanism. Background Art
[0002] Sand casting is a casting method that uses sand as the main molding material to prepare the mold. Sand casting is the most traditional casting method. The process of traditional sand casting includes: sand preparation, mold making, core making, molding, pouring, sand removal, grinding, inspection and other steps. In the traditional sand box casting production line, the upper sand box is placed with its front side facing upward. After the sand core is placed in the upper sand box, it needs to be turned 180°, that is, facing downward, so that it can be combined with the lower sand box for the subsequent step of combining the boxes and finally completing the casting. The traditional box turning step is mostly done manually with the help of simple tools. This method is not only labor-intensive and inefficient, but also the weight of the upper sand box itself plus the quality of the sand inside it make it very difficult to turn it over. In order to solve the problem of the weight of the sand box, the prior art uses lifting tools to lift the upper sand box, and then manually turns it over. The newly added lifting equipment not only increases the additional investment cost, but also requires a sufficiently large equipment operating space. In addition, there are safety hazards such as the sand box falling during the lifting process of the sand box. In addition, impurities remaining on the surface of the sand box during the operation are not removed, which will cause product defects. The sand box needs to be cooled during the operation to accelerate the cooling and molding of the product.
[0003] There are two driving modes for the flipping machine. One is that the motor drives the vulcanizing wheel to achieve the purpose of flipping through friction, and the other is that the motor drives the chain to achieve the purpose of flipping.
[0004] When the flip machine is driven by a motor to drive the vulcanizing wheel, slippage will occur. When the flip machine is driven by a motor to drive the chain, the chain will be loose, causing violent shaking when it reaches the stop position. These two passive limit mechanisms will cause certain impacts, making the flipping action unstable. Summary of the invention
