The invention discloses a 
casting guide rail seat device, which includes a guide rail and an 
operating table. The 
operating table on the guide rail is fixedly equipped with a bracket. A roller shaft is rolling inside the bracket. A roller and a driving 
pulley are fixed on the roller shaft. The roller rolls with the guide rail.  Contact, the driving 
pulley is driven by the belt to the driven 
pulley, the driven pulley is fixedly installed on the worm gear shaft, the worm gear shaft rolls in the bracket, a worm gear is fixed on the worm gear shaft, the worm gear and the worm engage in meshing motion, the worm rotates inside the tank, and the tank body  Fixed on the bracket, there is a ring gear fixed under the worm, which avoids the tediousness of manually adding 
lubricant and cleaning up debris, and avoids the situation where the 
machine continues to work when the 
machine's 
lubrication is poor, thereby preventing the 
machine from being damaged due to lack of 
lubrication.  Wear caused by 
lubricant, the lubricating oil is added according to the 
lubrication degree of the guide rail, so that there will not be too much lubricating oil on the guide rail, causing waste and affecting the appearance. The invention has strong practicability and is easy to popularize.
