Description

Technical Field

[0001] The utility model relates to the technical field of die casting, in particular to a shunt core for a knuckle die. Background Technique

[0002] The shunt core is a very important component in the die demolding process and is used to eject the casting from the die.

[0003] Patent Publication No. CN210587014U discloses a shunt core convenient for demolding, including a mounting plate. A limit seat is integrally formed on the top of the mounting plate. A cylinder is fixedly installed inside the limit seat near the top position through a partition. The output end of the cylinder is fixedly installed with a connecting head. An external thread is arranged on the outer side of the connecting head. A connecting rod is movably sleeved on the outer side of the connecting head. A connecting hole is opened on the inner side of the connecting rod. An internal thread is arranged on the inner side of the connecting hole. A guiding head is integrally formed at the top end of the connecting rod. An arc-shaped block is integrally formed at the top of the guiding head. A demolding groove is arranged around the outer surface of the guiding head.

[0004] The defects of the existing shunt core are as follows: when the shunt core is used for a long time, the thickness between adjacent demolding grooves on the guiding head is relatively thin, and it is easily corroded and causes water leakage after being washed by high-temperature molten aluminum for a long time, resulting in a batch of defective products; and the shunt core needs to be replaced frequently, wasting the wire-changing working hours and resulting in a relatively high production cost. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shunt core for a knuckle die to solve the problems raised in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a shunt core for a knuckle die, including a shunt core body. The top of the shunt core body is set as a round head. A demolding groove is opened at the top of the shunt core body. An external thread is arranged at the lower end of the shunt core body. A groove is opened in the middle of the bottom of the shunt core body, and the groove extends upward to the middle of the top of the shunt core body. A cooling pipe is arranged in the groove. A connecting sleeve is sleeved on the shunt core body at the position corresponding to the external thread. A through hole for the cooling pipe to pass through is opened inside the connecting sleeve.

[0007] The demolding groove at the top of the shunt core body is used to increase the demolding force. The cooling pipe is arranged in the groove, so that the coolant flows in the cooling pipe to cool the shunt core body and improve the service life of the shunt core.

[0008] Preferably, at least two demolding grooves are opened along the outer circumference of the top of the shunt core body and are parallel to each other. The overall area of demolding is increased, and the demolding force is increased, which is beneficial to demolding.

[0009] Preferably, the through hole is an inverted T shape, and both ends of the cooling pipe pass through both ends of the through hole respectively, enabling the coolant to flow in from one end of the cooling pipe and flow out from the other end, thus improving the cooling efficiency.

[0010] Preferably, a connector is threadedly installed at the bottom of the connecting sleeve, and a limit seat is movably sleeved at the bottom of the connector.

[0011] Preferably, a cavity is formed inside the limit seat, a partition is fixedly installed in the middle of the cavity, a cylinder is fixedly installed on the partition, and the output end of the cylinder is fixedly connected to the bottom of the connector. The connector is pushed out by the cylinder to drive the demolding of the split core body.

[0012] Preferably, a storage battery is fixedly installed at a position below the partition in the cavity, and the storage battery is electrically connected to the cylinder.

[0013] Preferably, a mounting plate is fixedly installed at the bottom of the limit seat, threaded holes are formed at both ends of the mounting plate, and threaded bolts are movably installed in the threaded holes.

[0014] Compared with the prior art, the utility model adopts the above technical solutions and has the following technical effects:

[0015] By setting the top of the split core body as a round head, the problem that the top of the split core body is easily corroded after being washed by high-temperature molten aluminum for a long time due to the thin thickness between adjacent demolding grooves is avoided, and the demolding pulling force is increased by using the lifting groove instead of the demolding groove; by forming a groove in the split core body and arranging a cooling pipe, the coolant in the cooling pipe cools the split core body, thereby improving the service life of the split core body.
