1. the device comprises a precast pin, 2, an inner pipe, 3, an outer pipe, 4, a connecting seat, 5, a sealing ring, 11, a cooling cavity, 31, a clearance part, 41, a water inlet, 42 and a water return port.
Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1-3, a front end point cooling assembly for a die casting die comprises a precast pin 1, an inner pipe 2, an outer pipe 3 and a connecting seat 4, wherein a cooling cavity 11 is axially concavely arranged on the precast pin 1, the outer pipe 3 is sleeved outside the inner pipe 2, and a gap is arranged between the inner pipe 2 and the outer pipe 3 and is used for backwater of cooling water. One end of the inner tube 2 and one end of the outer tube 3 are arranged on the connecting seat 4, a water inlet 41 and a water return opening 42 are arranged on the connecting seat 4, the water inlet 41 is connected with the inner tube 2, and the water return opening 42 is connected with the outer tube 3. The end of the outer tube 3 is in sealing connection with the cooling chamber 11. When in use, cooling water is injected into the cooling cavity 11 through the inner pipe 2, then backwater is returned from the gap between the inner pipe 2 and the outer pipe 3, and is discharged from a backwater port; since the end of the outer tube 3 is sealed with the cooling chamber 11, the cooling water cannot overflow, and therefore, the effective cooling position is only at the end of the outer tube 3, and then the partial cooling of the thick-wall region of the support column is realized, and the thin-wall region at the upper part of the support column is not cooled. The quality of the outer tube of the product is guaranteed, the internal quality is guaranteed, the qualification rate is greatly improved, and the air tightness of the product is guaranteed.
In one embodiment, as shown in fig. 1-3, the front end of the outer tube 3 is provided with a sealing ring 5. Specifically, the front end of the outer tube 3 is provided with an assembly groove, the sealing ring 5 is arranged in the sealing groove, the sealing ring 5 is axially limited, the sealing ring 5 is prevented from axially displacing, and the effective cooling range is further changed. In addition, the outer tube 3 is contacted with the precast pin 1 through a sealing ring, so that heat transfer is reduced, and cooling water is better controlled to be cooled.
In one embodiment, as shown in fig. 1-3, the outer wall of the outer tube 3 is recessed radially inward with a clearance 31. By arranging the clearance part 31, the contact area of the outer tube 3 and the precast pin 1 is reduced, heat transfer is reduced, and cooling water is prevented from being matched with the precast pin 1 through the outer tube 3 to cool the upper part of the support column.
In one embodiment, as shown in fig. 1-3, the front end of the inner tube 2 protrudes from the outer tube 3.
When the cooling device is used, as shown in fig. 1-3, cooling water enters the inner tube 2 from the water inlet 41, the cooling water is guided into the cooling cavity through the inner tube 2, the outer tube 3 is matched with the precast pin through the sealing ring to form an effective cooling cavity, and the cooling water flows back to the water return port 42 from a gap between the outer tube 3 and the inner tube 2 after filling the effective cooling cavity. The cooling water is only used for circularly cooling the bottom of the cooling cavity.
The foregoing is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model; modifications and equivalent substitutions are intended to be included in the scope of the claims without departing from the spirit and scope of the present utility model.
