the utility model provides a die-casting drift lubricating structure, is close to the one end of drift at the connector and offers first oil groove, and the one end that is close to the jumper bar at the connector offers the second oil groove, the outer circumference of first oil groove on evenly set up the emollient spout of perpendicular intercommunication with it, set up intercommunication first emollient runner each other between first oil groove and second oil groove, the third oil groove that communicates with the second oil groove is seted up to the one end that the jumper bar is close to the connector, opens the second emollient runner that has communicated with the third oil groove on the jumper bar.
Furthermore, a sealing groove is formed in the punch and used for placing a sealing washer.
Furthermore, an oil groove pressing plate is fixedly connected to the position, close to the punch, of the first oil groove.
The utility model also provides a drift lubricating arrangement, including drift, connector and jumper bar, drift and jumper bar pass through the connector to be connected, still include foretell die-casting drift lubricating structure.
Furthermore, a lubricant inlet and a cooling water inlet are formed at one end of the punch rod, which is far away from the connector.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a die-casting drift lubricating structure offers the emollient runner on jumper bar and connecting head respectively to evenly set up emollient spout on the outer circumference of connector jumper bar end oil groove, spray emollient in pressing the room, realize the drift and the even lubrication of pressing the room, effectively improve the guard action to the die-casting drift, improve the inside quality of foundry goods.
