[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is as follows:

[0019] Please see Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the horizontal cold chamber die-casting machine injection punch cooling device according to the first embodiment of this utility model. Figure 2 This is a schematic diagram of the cooling assembly according to the first embodiment of the present invention. Figure 3 This is a cross-sectional structural diagram of the connecting component of the first embodiment of this utility model. This utility model provides a cooling device for the injection punch of a horizontal cold chamber die casting machine, including a punch body 101, a cooling component, and a connecting component. The cooling component includes a cold jacket 102, a heat exchange tube 103, a water inlet pipe 104, a water outlet pipe 105, and a connecting tube 106. The connecting component includes a connecting sleeve 107, a connecting tube 108, a fixing spring 109, a fixing seat 110, a fixing ball 111, a connecting rod 112, and a sliding sleeve 113. The aforementioned solution solves the problem that when the injection punch cooling device of a horizontal cold chamber die casting machine is used, the connection of the pipe body through the threaded sleeve shaft makes it impossible to quickly disassemble and install the joint, resulting in low replacement efficiency of the device. It can be understood that the aforementioned solution can be used in scenarios where the injection punch cooling device of a horizontal cold chamber die casting machine is quickly installed and disassembled, and can also be used to solve the problem of cooling water circulation in the injection punch cooling device of a horizontal cold chamber die casting machine.

[0020] In this specific embodiment, the cold jacket 102 is slidably connected to the punch body 101 and located outside the punch body 101; the heat exchange tube 103 is fixedly connected to the cold jacket 102 and located inside the cold jacket 102; the water inlet pipe 104 is fixedly connected to the heat exchange tube 103 and located at the bottom of the heat exchange tube 103; the water outlet pipe 105 is fixedly connected to the heat exchange tube 103 and located at the top of the heat exchange tube 103; the connecting assembly is located outside the water inlet pipe 104 and the water outlet pipe 105; the punch body 101 is used to stamp the part to be die-cast; and the cold jacket 102 provides protection for the punch body 101. The heat exchange tube 103 is used to exchange heat between the cold jacket 102 and the punch body 101. The water inlet pipe 104 is used to introduce coolant into the heat exchange tube 103. The water outlet pipe 105 is used to discharge the cooled coolant after heat exchange from the heat exchange tube 103. During installation, the insertion tube 106 is inserted into the connecting sleeve 107 and fixed by the fixing ball 111 to facilitate the installation of the cooling assembly. During disassembly, the sliding sleeve 113 is moved upward, which simultaneously moves the connecting rod 112 and the fixing seat 110 upward, compressing the fixing spring 109 and releasing the fixing ball 111 from fixing the insertion tube 106, thus facilitating the disassembly of the cooling assembly.

[0021] The number of the insertion tubes 106 is two. The two insertion tubes 106 are fixedly connected to the water inlet pipe 104 and the water outlet pipe 105 respectively, and are located on the outside of the water inlet pipe 104 and the water outlet pipe 105 respectively. The insertion tubes 106 cooperate with the fixed ball 111 to connect the water inlet pipe 104 and the water outlet pipe 105 to the external cooling circulation device through the connecting assembly.

[0022] Secondly, there are two connecting sleeves 107, which are slidably connected to the insertion tube 106 and located on the outside of the insertion tube 106. There are also two connecting tubes 108, which are fixedly connected to the connecting sleeves 107 and pass through the connecting sleeves 107. The connecting sleeves 107 provide support for the connecting assembly, and the connecting tubes 108 are used to connect to an external circulation device to facilitate the recycling of coolant.

[0023] Furthermore, the fixing spring 109 is fixedly connected to the connecting tube 108 and located at the bottom of the connecting sleeve 107. The fixing seat 110 is fixedly connected to the fixing spring 109 and located at the bottom of the fixing spring 109. There are multiple fixing balls 111, which are rotatably connected to the fixing seat 110 and located in the middle of the fixing seat 110. The fixing spring 109 provides support and elasticity to the fixing seat 110. The fixing seat 110 is a boss seat that cooperates with the connecting sleeve 107 to fix the position of the fixing balls 111. The fixing balls 111 are used to clamp the insertion tube 106, which facilitates the connection and cooperation of the connecting tube 108 with the water inlet pipe 104 and the water outlet pipe 105.

[0024] Finally, there are multiple connecting rods 112, each fixedly connected to the fixed base 110 and passing through the sliding sleeve 113. The sliding sleeve 113 is fixedly connected to the connecting rod 112 and located outside the connecting rod 112. The connecting rod 112 provides support for the sliding sleeve 113. The sliding sleeve 113 is used to control the position of the fixed base 110. When the fixing ball 111 is released from fixing the insertion tube 106, the sliding sleeve 113 and the connecting rod 112 slide upward, causing the fixed base 110 to compress the fixing spring 109. At the same time, the cooperation between the fixed base 110 and the sliding sleeve 113 is released, so that the fixing ball 111 can retract into the interior of the fixed base 110. This releases the fixing ball 111 from fixing the insertion tube 106, making it easier to disassemble the cooling assembly.

[0025] Using the horizontal cold chamber die-casting machine injection punch cooling device of this embodiment, the punch body 101 is used to punch the part to be die-cast, the cold jacket 102 is used to protect the punch body 101, the heat exchange tube 103 is used to exchange heat between the cold jacket 102 and the punch body 101, the water inlet pipe 104 is used to introduce coolant into the heat exchange tube 103, and the water outlet pipe 105 is used to discharge the cooled coolant from the heat exchange tube 103. During installation, the insertion tube 106 is inserted into the connecting sleeve 107, and through the... The fixed ball 111 secures the insertion tube 106, facilitating the installation of the cooling assembly. During disassembly, the sliding sleeve 113 is moved upward, simultaneously driving the connecting rod 112 and the fixing seat 110 upward, compressing the fixing spring 109, and releasing the fixed ball 111 from securing the insertion tube 106, thus facilitating the disassembly of the cooling assembly. This solves the problem that in the use of the horizontal cold chamber die-casting machine's injection punch cooling device, the connection of the tube body via a threaded sleeve shaft makes it impossible to quickly disassemble and install the joint, resulting in low device replacement efficiency.
