Description

Technical Field

[0002] High-pressure point cooling plays a pivotal role in changing the mold temperature gradient and shifting the location of shrinkage defects in products during high-pressure casting. It is mostly used for cooling pins with slender structures. In the existing high-pressure cooling water structure, the pin head is connected to the high-pressure cooling water pipe through a tapered pipe thread. The high-pressure cooling water pipe passes through a hollow quick-change rod to fix the pin. The overall structure adopts a split structure, which leads to a series of problems such as cumbersome and complicated on-site replacement operations and easy damage due to the thin diameter of the high-pressure cooling water pipe.

[0003] The existing high-pressure point cooling water pipe is connected to the dynamic model pin through a tapered pipe thread and passes through a hollow structure of the mold pin quick-change rod to achieve quick replacement of the dynamic model pin. The water pipe of this structure has low rigidity and is easily damaged during on-site use and assembly. The high-pressure point cooling water pipe needs to be replaced frequently, and the quick-change structure takes into account the water inlet and outlet problems of the high-pressure water pipe during installation. The dynamic model pin can only be installed on the back of the dynamic mold frame and can only be quickly replaced. When replacing the pin and the high-pressure cooling water pipe, the bottom plate, ejector plate and push plate behind the dynamic mold frame must be removed, which makes replacement inconvenient, time-consuming and labor-intensive to disassemble, and has low compatibility with different castings.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] The utility model is further described in detail below with reference to the accompanying drawings:

[0041] See also Figures 1 to 5 The embodiment of the utility model discloses a high-pressure cooling water pipe quick-change structure, including a quick-change water pipe 213, one end of the quick-change water pipe 213 is connected to the dynamic model pin 210 to be cooled, and the other end is connected to the water pipe connector 215; the water pipe connector 215 is provided with a water outlet and a water inlet, the water pipe connector 215, the quick-change water pipe 213 and the dynamic model pin 210 cooperate to form a connected cavity, a spot cooling tube core 212 is arranged in the cavity, the inlet end of the spot cooling tube core 212 is connected to the water inlet, and the water outlet is connected to the cavity. In this embodiment, a water channel is opened inside the quick-change water pipe 213 to replace the original water pipe, thereby improving the rigidity of the water pipe, making it not easy to be damaged during on-site use and assembly, and there is no need to frequently replace the high-pressure spot cooling water pipe.

[0042] Furthermore, in the present embodiment, the interior of the water pipe connector 215 includes a first cavity and a second cavity; wherein, the water inlet is opened on the side wall corresponding to the first cavity, and the water outlet is opened on the side wall corresponding to the second cavity, and a spot cooling core positioning column 216 is arranged in the first cavity, and the interior of the cooling core positioning column 216 is a hollow structure, and the hollow structure is connected to the water inlet, and the spot cooling core 212 extends into the interior of the spot cooling core positioning column 216 and is connected to the hollow structure, and there is a gap between the inner wall of the cavity formed by the spot cooling core 212 and the water pipe connector 215, the quick-change water pipe 213 and the dynamic model pin 210, thereby providing a water channel for the return of cooling water.

[0043] Furthermore, in this embodiment, a plug 217 is provided at the end of the water pipe connector 215 away from the quick-change water pipe 213, and the plug 217 is stuck in the port of the second cavity. The plug 217 and the water pipe connector 215 can fix the cold tube core positioning column 216 through the tapered pipe thread, and can also realize the water channel sealing of the head of the water pipe connector 215.

[0044] Furthermore, in this embodiment, the spot cooling core 212 and the spot cooling core positioning column 216 are connected by threads to realize the inlet and outlet of high-pressure cooling water. The independent setting of the spot cooling core positioning column 216 facilitates the processing of the water pipe connector 215.

[0045] Furthermore, in the present embodiment, the quick-change water pipe 213 is connected to the water pipe connector 215 by threads, wherein two second O-rings 214 are axially arranged in the corresponding grooves of the quick-change water pipe 213 to realize the water channel sealing of the pin end.

[0046] Furthermore, in this embodiment, the dynamic model pin 210 is tightly connected to the quick-change water pipe 213 through threads, and two first O-rings 211 are axially installed at the connection to achieve water channel sealing.

[0047] See also Figure 6 to Figure 7 The present embodiment also discloses an installation structure of a high-pressure cooling water pipe quick-change structure.

In the past, the dynamic model pin or the high-pressure spot cooling pipe had to be stopped for replacement, and the blocking parts had to be removed through a series of tedious operations, which was time-consuming and laborious. The new integrated high-pressure cooling water structure can directly quickly replace the dynamic model pin to the bottom plate surface, thereby realizing the direct replacement of the vulnerable pin on the die-casting machine, which brings great convenience to on-site production.

[0050] The device has a high degree of application matching and can be applied to die-casting molds of different sizes by adjusting the specifications and dimensions.

[0051] The working of this embodiment is far from:

[0052] After assembly is completed, the water inlet is connected to the high-pressure water inlet pipeline of the external high-pressure spot cooling machine. The inlet water passes through the spot cooling tube core positioning column 216 and flows along the inner wall of the spot cooling tube core 212 to the head of the dynamic model pin 210. The circulating high-pressure cooling water realizes the cooling of the forming part of the dynamic model pin, and the return water flows through the outer wall of the spot cooling tube core 212 to the water outlet of the water pipe connector 215, thereby realizing the entire high-pressure cooling water circuit circulation.
