Description

Technical Field

[0001] This utility model relates to the field of compressor volute mold manufacturing technology, and in particular to a quick-change connector device for conformal cooling water channels in compressor volute molds. Background Technology

[0002] In the die-casting process of compressor volutes, the cooling effect of the mold directly affects the molding quality, production efficiency, and mold lifespan. Due to the complex and irregular structure of the compressor volute, conformal cooling channels adapted to the shape of the volute are usually installed inside the mold to achieve uniform cooling. These conformal cooling channels need to be connected to an external cooling system via connectors to ensure the circulation and supply of coolant. Currently, most cooling water channel connectors on the market are threaded connections. Threaded connectors require multiple rotations during installation and disassembly, making the operation cumbersome. Especially in the confined space of a mold, the disassembly and assembly efficiency is extremely low, seriously affecting the production cycle. Furthermore, the sealing structure of traditional connectors often uses a single sealing ring. Under the impact of high-pressure coolant, the sealing ring is prone to aging and failure, further exacerbating the risk of leakage.

[0003] To address the issues of cumbersome disassembly and assembly and poor sealing performance of traditional cooling water channel joints, we propose a quick-change joint device for conformal cooling water channels in compressor volute molds. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-change connector device for conformal cooling water channels in compressor volute molds, which aims to solve the technical problems in the prior art.

[0005] To achieve the above objectives, this utility model employs a quick-change connector device for conformal cooling water channels in a compressor volute mold, comprising a slider snap-fit ​​sealing assembly. The slider snap-fit ​​sealing assembly includes a tube body, a sealing sleeve, a double sealing ring, and a pressure chamber. The sealing sleeve is disposed on one side of the tube body, the double sealing ring is disposed on the inner arm of the sealing sleeve, and the pressure chamber is disposed at the center of the inner arm of the double sealing ring.

[0006] The slider snap-fit ​​sealing assembly further includes a groove and a slider. The groove is disposed on one outer surface of the tube body, and the slider is slidably disposed on the outer surface of the tube body. The slider is also disposed inside the groove.

[0007] The slider snap-fit ​​sealing assembly further includes a control button and a lifting column. The control button is located on the inner side of the slider away from the tube body, and the lifting column is located inside the tube body. The end of the lifting column near the slider passes through the tube body and is fixedly connected to the control button, and is located on the side of the control button near the slider.

[0008] The slider snap-fit ​​sealing assembly further includes a return spring and a locking plate. The return spring is disposed on the outer surface of the lifting column, and the locking plate is disposed on the side of the lifting column away from the tube body, and the locking plate is disposed in the form of a semi-circular arc plate.

[0009] The slider snap-fit ​​sealing assembly further includes a connecting thread and a positioning bracket. The connecting thread is disposed on the inner wall of the tube body, and the positioning bracket is disposed on the outer surface of the tube body and the sealing sleeve, respectively.

[0010] Beneficial effects: 1. The present invention relates to a quick-change connector device for conformal cooling water channels of a compressor volute mold. During installation, the tube body and the sealing sleeve are placed in the designated position according to the positioning frame. Then, the operator manually slides the slider to the inside of the groove near the sealing sleeve. Then, the operator presses the control button to lock the lifting column and the locking plate to the installation part, thereby achieving the purpose of quick installation or disassembly.

[0011] 2. The present invention provides a quick-change connector device for conformal cooling water channels of a compressor volute mold. After installation, the double sealing ring inside the sealing sleeve will be used for composite sealing. The air pressure chamber forms a negative pressure effect due to the different external pressures, thereby achieving multiple seals and solving the problem of poor sealing effect.

[0017] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a side view of the entire utility model. Figure 3 This is a utility model Figure 2 The AA-line structural cross-sectional view shows that this utility model provides a quick-change connector device for the conformal cooling water channel of a compressor volute mold, including the slider snap-fit ​​sealing assembly. The slider snap-fit ​​sealing assembly includes the tube body 101, the sealing sleeve 103, the double sealing ring 104, and the air pressure chamber 105. The sealing sleeve 103 is disposed on one side of the tube body 101, the double sealing ring 104 is disposed on the inner arm of the sealing sleeve 103, and the air pressure chamber 105 is disposed at the center of the inner arm of the double sealing ring 104.

[0018] In this embodiment, the pipe body 101 is the core channel for coolant flow and also provides a mounting carrier for other components. The sealing sleeve 103 serves a dual function of "transition connection + sealing protection," preventing external impurities from entering the sealing area and enhancing the connection stability between the pipe body 101 and the external pipeline. The double sealing rings 104 are fixed to the inner wall of the sealing sleeve 103 in a "stacked" or "nested" manner, forming two independent sealing barriers to prevent coolant leakage from the connection gap. When the external pipeline is inserted into the sealing sleeve 103, the air pressure chamber 105 will experience a slight volume change due to pipeline compression, forming a local negative pressure.

[0019] Furthermore, the slider snap-fit ​​sealing assembly also includes the groove 102 and the slider 107. The groove 102 is disposed on one side of the outer surface of the tube body 101, and the slider 107 is slidably disposed on the outer surface of the tube body 101, and the slider 107 is also disposed inside the groove 102.

[0020] In this embodiment, the slide groove 102 has limiting protrusions at both ends to prevent the slider 107 from sliding excessively and disengaging from the tube body 101. The slider 107 is adapted to the curvature of the outer wall of the tube body 101, and has a "protruding tenon" on its inner side that matches the slide groove 102, allowing it to slide axially along the slide groove 102. The outer side of the slider 107 has anti-slip textures for easy manual operation by workers. At the same time, a "locking protrusion" is provided at the end of the slider 107 near the sealing sleeve 103 for locking with the slot of the external pipeline.

[0021] Furthermore, the slider snap-fit ​​sealing assembly also includes the control button 108 and the lifting column 109. The control button 108 is disposed on the inner side of the slider 107 away from the tube body 101, and the lifting column 109 is disposed inside the tube body 101. The end of the lifting column 109 near the slider 107 passes through the tube body 101 and is fixedly connected to the control button 108, and is located on the side of the control button 108 near the slider 107.

[0022] In this embodiment, the control button 108 conforms to the inner curvature of the slider 107 and is fixedly connected to the slider 107 by screws. Its surface is provided with pressing protrusions for easy pressing by the operator's fingers. The control button 108 has a through hole in the middle for connecting to one end of the lifting column 109 to realize the transmission of force. The outer surface of the lifting column 109 is provided with a guide ring to ensure that it moves without deviation along the axial direction. At the same time, the inner wall of the guide hole of the tube body 101 is provided with a sealing ring to prevent coolant from leaking from the hole.

[0023] Furthermore, the slider snap-fit ​​sealing assembly also includes the return spring 110 and the locking plate. The return spring 110 is disposed on the outer surface of the lifting column 109, and the locking plate is disposed on the side of the lifting column 109 away from the tube body 101, and the locking plate is disposed in the form of a semi-circular arc plate.

[0024] In this embodiment, the return spring 110 is sleeved on the outer surface of the lifting column 109 located inside the tube 101. One end abuts against the inner wall step of the tube 101, and the other end abuts against one side of the locking plate. In the initial state, it is in a slightly compressed state to provide a restoring force for the lifting column 109. The curvature of the locking plate is adapted to the inner curvature of the tube 101, and its inner side matches the annular locking groove of the external pipeline port. The two ends of the locking plate are provided with guide holes and are connected to the fixed seat inside the tube 101 through pins. It can rotate slightly around the pins to achieve "opening and closing" locking.

[0025] Furthermore, the slider snap-fit ​​sealing assembly also includes the connecting thread 112 and the positioning bracket 106. The connecting thread 112 is disposed on the inner wall of the tube body 101, and the positioning bracket 106 is disposed on the outer surface of the tube body 101 and the sealing sleeve 103 respectively.

[0026] In this embodiment, the connecting thread 112 is used to connect with the external thread port of the conformal cooling water channel to fix the joint to the mold cooling water channel. The positioning bracket 106 is an "L-shaped" bracket made of stainless steel, which is fixed to the outer surface of the middle part of the tube body 101 and the outer surface of the sealing sleeve 103 by welding to achieve precise installation and positioning of the joint on the mold.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
