Embodiment Construction
[0036] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0037] Please refer to the attached Figure 1-5 As shown, the embodiment of the present invention discloses a sprue bushing cooling structure, including a sprue bushing main body 10, and the middle part of the sprue bushing main body 10 is provided with a pouring hole 11 passing through opposite ends, and the sprue bushing main body One end of 10 is provided with a plurality of cooling holes 12 extending axially to the other end around the circumference of the pouring hole 11. The cooling holes 12 extend to the other end of the sprue bushing main body 10 without passing through the sprue bushing main body 10. The cooling holes 12 are evenly spaced apart, and each cooling hole 12 is provided with a cooling device corresponding to it.

The invention discloses a sprue sleeve cooling structure and a temperature control method. The sprue sleeve cooling structure includes a sprue sleeve main body, and the sprue sleeve main body is provided with a plurality of cooling holes, each of which corresponds to A cooling device is provided; the cooling device includes an adapter, a first water receiving pipe, a second water receiving pipe and a water passage, the adapter is provided with a first water flow channel and a second water flow channel, and one end of the water passing pipe is connected to One end of the second water flow channel, the first water connection pipe is installed on the adapter to communicate with the first water flow channel, and the second water connection pipe is installed on the adapter to communicate with the second water flow channel; the adapter is installed on the cooling hole At the open end, the water pipe extends into the bottom of the cooling hole and a water passage is formed between the outer peripheral wall of the water pipe and the wall of the cooling hole. Adopting the above sprue sleeve cooling structure has good cooling effect and high efficiency, and can increase the service life of the sprue sleeve.
Description
technical field [0001] The invention relates to the field of molds, in particular to a sprue sleeve cooling structure and a temperature control method. Background technique [0002] The sprue sleeve is also called the sprue, the sprue, and the sprue (English translation: Ingate Sleeve). It is a part of the flow channel that allows the molten plastic material to be injected from the nozzle of the injection molding machine into the interior of the mold. It is used to connect the molding mold and the mold. Metal accessories for injection molding machines. [0003] During the injection molding process, the temperature of the sprue sleeve is increased by the heat transfer of the pouring liquid, so it is necessary to cool down the sprue sleeve to prevent the temperature of the sprue sleeve from overheating. There are cooling methods such as water cooling and air cooling in the prior art. Among them, the cooling efficiency of air cooling is insufficient, and water cooling tends to...
