Technical Field

[0001] The utility model relates to the technical field of mold cooling, in particular to a mold cooling mechanism with recyclable cooling water. Background Art

[0002] Molds generally refer to tools or equipment used in manufacturing molding processes, which can be used to produce products of various shapes. Molds play a vital role in industrial production and are commonly found in metal processing, plastic molding, glass manufacturing and other fields. When in use, molds generally require a matching cooling mechanism, which generally uses water cooling. The current cooling mechanism requires the water pipe to be separated from the mold when the mold is changed, and cooling water will remain in the water pipe or the mold, which may cause the water channel of the mold to rust and the water to fall to the ground, affecting the factory's 5S. Therefore, those skilled in the art provide a mold cooling mechanism with recyclable cooling water to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0021] Example

[0022] See also Figure 1 to Figure 4In this embodiment, a mold cooling mechanism with recyclable cooling water is provided, including a mold 1, a chiller 2 and a drain plate 3. The chiller 2 is connected to the inlet of the drain plate 3 through an inlet pipe 4, and the outlet of the drain plate 3 is connected to the chiller 2 through a return pipe 5. At the same time, pipe joints 31 are provided at the corresponding inlet pipe 4 and return pipe 5 on the drain plate 3. A conduit 32 is installed on both pipe joints 31, and the other end of the conduit 32 is connected to the mold 1. When cooling the mold 1, the cooling water in the chiller 2 enters the drain plate 3 through the inlet pipe 4, and is transported to the mold 1 through the corresponding pipe joint 31 and conduit 32 to achieve a cooling effect, and then the used cooling water is returned to the drain plate 3 through the conduit 32 corresponding to the return pipe 5, and then the water is transported to the chiller 2 again through the return pipe 5 connected thereto, so that the water that absorbs the superheat is cooled and recycled;

[0023] In this process, after the cooling water passes through the mold 1, some impurities may exist, so a filter 7 is installed on the return pipe 5. The filter 7 is detachably connected to the return pipe 5, which is convenient for disassembly and cleaning.

[0024] Moreover, a valve 6 is installed on the water inlet pipe 4. At the same time, an air pipe 33 is also provided on the drain plate 3. The air pipe 33 is connected to the pipe joint 31 of the water inlet pipe 4. This design can drain the water inside the mold 1 when the mold 1 is changed, and discharge the water into the chiller 2, thereby avoiding the residual water flowing to the ground when changing the mold and affecting the factory 5S and the rust of the water channel of the mold 1;

[0025] Its working process is that when changing the mold, the valve 6 is closed, and then the external air source is connected to the air pipe 33. At this time, the return pipe 5, the mold 1 and the drain plate 3 form a passage. After the gas is introduced into the air pipe 33, it is introduced into the mold 1 through the conduit 32 originally connected to the water inlet pipe 4, and the residual water is pushed by pressure, and finally returned to the chiller 2 from the return pipe 5, realizing the recovery of the residual water and preventing it from spilling on the ground and remaining in the mold 1;

[0026] The filter 7 includes a housing 1 71 and a housing 2 72. The housing 1 71 and the housing 2 72 are connected by threads. After the housing 1 71 and the housing 2 72 are disassembled, they can be easily separated and the inside can be cleaned, which is convenient to operate.

[0027] At the same time, flange 2 73 is provided at the outer ends of shell 1 71 and shell 2 72, and flange 2 73 is connected to the return pipe 5. Flange 1 51 is provided on the return pipe 5 corresponding to flange 2 73, and flange 1 51 and flange 2 73 are fixed by screws 8. Therefore, when installing the filter 7, flange 1 51 and flange 2 73 are aligned, and then screw 8 is screwed on, otherwise it can be removed;

[0028] The filter element 74 is disposed inside the housing 1 71 and the housing 2 72. The filter element 74 is disposed separately from the housing 1 71 and the housing 2 72. Therefore, after the housing 1 71 and the housing 2 72 are twisted apart, the filter element 74 can be taken out and cleaned separately.

[0029] The filter element 74 includes two filter screens 741. Arranging multiple filter screens 741 can improve the filtering effect. The two filter screens 741 are connected and fixed by a connecting rod 742. At the same time, multiple elastic rods 743 are arranged on the side away from the filter screens 741. The elastic rods 743 can facilitate the removal of the filter element 74 from the filter 7. During installation, the shell 1 71 and the shell 2 72 are tightened and approached to each other, thereby compressing the elastic rods 743. Conversely, when the two are separated, the elastic rods 743 lose the compression force and automatically pop out from the shell 1 71 and the shell 2 72, which facilitates the removal of the filter element 74.

[0030] The utility model installs a valve 6 on the water inlet pipe 4 and sets an air pipe 33 on the drain plate 3, so that when changing the mold, after the valve 6 is closed, the drain plate 3, the air pipe 33, the mold 1 and the return pipe 5 form a passage, and after the gas is passed through the air pipe 33, the remaining cooling water can be pressurized and returned to the chiller 2, thereby avoiding the problem that the remaining cooling water flows to the ground or remains in the mold 1 during the mold change, affecting the factory's 5S standard and causing the mold 1 water channel to rust.

[0031] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
