DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-Figure 4A mold frame with a cooling mechanism shown in the figure includes an upper mold frame 1 and a lower mold frame 2. A feed hole 101 is opened at the central axis of the upper mold frame 1, and upper mold forming grooves 102 are arranged on both sides of the feed hole 101. An upper cooling channel tube 103 is arranged inside the upper mold frame 1, and a plurality of inner joints 104 are arranged inside the upper cooling channel tube 103. The upper mold frame 1 is slidably connected to the lower mold frame 2, and a plurality of sliding rods 201 are arranged on the top of the lower mold frame 2. A lower cooling channel tube 202 is arranged inside the lower mold frame 2, and an external joint 203 is fixedly connected inside the lower cooling channel tube 202. The utility model arranges a plurality of inner joints inside the upper cooling channel tube in the upper mold frame, and a lower cooling channel tube is arranged inside the lower mold frame, and an external joint is fixedly connected inside the lower cooling channel tube, and a plurality of sealing pads are arranged inside the external joint, and are plugged with the inner joint to ensure perfect docking under any water pressure, thereby effectively avoiding the problem of cooling water flowing to the forming groove.

[0021] Furthermore, a plurality of sealing rings 204 are provided inside the external joint 203, and a filter plate 1 207 is provided below the sealing ring 204. The external joint is equipped with a plurality of sealing rings, and the main function of the sealing ring is to ensure that the cooling water does not leak from the joint. The sealing ring is made of highly elastic material, and can still maintain a good sealing effect under the impact of high-pressure water flow, effectively preventing the waste of water resources, and also avoiding mold damage or product quality problems that may be caused by water leakage. A filter plate 1 is provided below the sealing ring inside the external joint, and its main function is to prevent impurities and particulate matter from entering the cooling water channel and prevent the sealing pad from falling inside the lower cooling channel tube when it is installed.

[0022] Furthermore, the outer joint 203 is plugged into the inner joint 104, and a filter plate 105 is provided inside the inner joint 104. By snap-fitting the outer joint and the inner joint and adding a filter plate 2 inside the inner joint, it is ensured that the cooling water can flow smoothly between the two joints, and the sealing and stability of the connection are greatly enhanced, and these possible impurities are intercepted again to ensure the purity of the cooling water, thereby protecting the cooling system of the mold from contamination.

[0023] Furthermore, the lower cooling channel tube 202 is composed of a main water pipe 205 and a connecting pipe 206. The main water pipe 205 is fixedly connected to the external joint 203, and the connecting pipe 206 is fixedly connected to the main water pipe 205. The lower cooling channel tube is composed of the main water pipe and the connecting pipe, which effectively ensures that the cooling water can flow into the mold stably and continuously, and there will be no leakage or interruption due to unstable connection. The cooling system can still maintain normal operation under high pressure, greatly improving the cooling efficiency and stability of the mold.

[0024] Furthermore, the upper cooling channel tube 103 is composed of a water outlet pipe 106 and a connecting pipe 107. The water outlet of the water outlet pipe 106 is provided with a connector 108. The inner diameter of the connector 108 is smaller than the inner diameter of the water outlet pipe 106. The upper cooling channel tube is composed of the water outlet pipe, the connecting pipe 2 and the connector. Since the inner diameter of the connector is small, when the fluid passes through the channel with a reduced cross-sectional area, its flow rate will increase accordingly, which helps to prevent the cooling water from being blocked at the water outlet and ensures that the cooling water can be quickly and effectively discharged from the mold, thereby improving the cooling efficiency.

[0025] Furthermore, the lower cooling channel tube 202 and the upper cooling channel tube 103 are provided with a plug 3 at one end of the channel. By providing the plug at one end of the channel of the lower cooling channel tube and the upper cooling channel tube, the main function of the plug is to close one end of the channel of the cooling channel tube, ensuring that the cooling water flows in the channel according to a predetermined path without leaking from one end of the channel, thereby preventing the waste of water resources and avoiding other problems that may be caused by cooling water leakage.

[0026] In this solution, the working process is as follows: while the raw materials are being injected, the cooling system starts to work. The cooling water flows in through the lower cooling channel tube inside the lower mold frame, and then passes through the external joint to be plugged into and matched with the internal joint in the upper cooling channel tube inside the upper mold frame, thus achieving the cooling water channel docking of the upper and lower mold frames. In this process, the filter plate 2 inside the internal joint will perform secondary filtration on the cooling water to further ensure the cleanliness of the water quality; after the cooling water flows through the upper cooling channel tube, it will flow out through the channel composed of the outlet pipe and the connecting pipe 2. The outlet of the outlet pipe is provided with a connector, the inner diameter of which is smaller than the inner diameter of the outlet pipe. Such a design can speed up the flow rate of the cooling water and improve the cooling efficiency.

[0027] During the entire cooling process, plugs are provided at one end of the channels opened by the lower cooling channel tube and the upper cooling channel tube to ensure that cooling water will not leak from one end of the channel, thus improving the sealing and stability of the cooling system.
