Abstract

The invention discloses a cooling structure inside a mold. The mold comprises a male mold core and a female mold core. An ejector pin is arranged in the male mold core. The cooling structure comprises a cold water jacket, a first sealing ring and a second sealing ring, wherein the periphery of the ejector pin is sleeved with the cold water jacket, and the periphery of the cold water jacket is provided with a first sealing ring groove and a second sealing ring groove; the first sealing ring is arranged in the first sealing ring groove; and the second sealing ring is arranged in the second sealing ring groove. The female mold cold water jacket is arranged around a hot pouring nozzle of the female mold core, and thus an effective cooling effect can be achieved, the molding time is shortened, and the production efficiency is improved. Because the cold water jacket is close to the centers and a tilting pin or the ejector pin of the mold cores, the centers and the tilting pin or the ejector pin of the mold cores can be cooled effectively, and the molding time is shortened.

Description

Cooling structure in mould

[technical field]

The present invention relates to cooling structure, particularly relate to cooling structure in a kind of mould.

[background technology]

Some plastic cement products, when shaping, need use to hot filling nozzle structure, and the temperature around this hot filling nozzle Very high, correspondingly the molding time of product is longer.

In view of this, it is necessary in fact to develop cooling structure in a kind of mould, to solve the problems referred to above.

[content of the invention]

Therefore, it is an object of the invention to provide cooling structure in a kind of mould, to solve in existing mold structure Owing to there is hot filling nozzle, temperature is very high, the problem of molding cycle length.

In order to achieve the above object, the present invention provide mould in cooling structure, this mould include male die core and Mother module core, is provided with thimble in described male die core, and this cooling structure includes:

Cold water jacket, it is sheathed on around described thimble, described cold water jacket has and around has the first sealing ring Groove and the second seal groove；

First sealing ring, is located in described first seal groove；

Second sealing ring, is located in described second seal groove.

Optionally, described cold water jacket is near described male die core and mother module core binding site.

Optionally, also having taper pin in described male die core, described cold water jacket is near described taper pin.

Optionally, described cold water jacket is near described thimble.

Optionally, the internal diameter of described first sealing ring is less than the internal diameter of described second sealing ring.

Optionally, this cooling structure also includes master mold cold water jacket, is located at around the hot filling nozzle in described mother module core.

Optionally, described master mold cold water jacket is near described male die core and mother module core binding site.

Optionally, there is the 3rd seal groove and the 4th seal groove around this master mold cold water jacket, the described 3rd It is provided with the 3rd sealing ring in seal groove, in described 4th seal groove, be provided with the 4th sealing ring.

Optionally, the internal diameter of described 3rd sealing ring is more than the internal diameter of described 4th sealing ring.

Compared to prior art, utilize cooling structure in the mould of the present invention, due to the heat filling of described mother module core Mouth is provided around described master mold cold water jacket, such that it is able to reach cooling effect effectively, shortens molding time, Improve production efficiency；Owing to described cold water jacket is near described die center and described taper pin or thimble position Put, can effectively cool down die center and described taper pin or thimble, shortening forming time.

[detailed description of the invention]

Refer to Fig. 1, Fig. 2, Fig. 1 be the present invention mould in cooling structure schematic diagram, Fig. 2 be in Fig. 1 The perspective view of cold water jacket.

In order to achieve the above object, cooling structure in the mould that the present invention provides, this mould includes male die core 101 With mother module core 102, being provided with thimble 103 in described male die core 101, this cooling structure includes:

Cold water jacket 104, it is sheathed on around described thimble 103, described cold water jacket 104 has and around has First seal groove and the second seal groove；

First sealing ring 105, is located in described first seal groove；

Second sealing ring 106, is located in described second seal groove.

Wherein, described cold water jacket 104 is near described male die core 101 and mother module core 102 binding site；Described Also having taper pin (not shown) in male die core 101, described cold water jacket 104 is near described taper pin；Described cold Water jacket 104 is near described thimble 103.Thus can effectively cool down die center and described taper pin or thimble 103, Shortening forming time.

Wherein, the internal diameter of described first sealing ring 105 is less than the internal diameter of described second sealing ring 106.

Please in conjunction with refering to Fig. 1, Fig. 3, Fig. 3 is the perspective view of master mold cold water jacket in Fig. 1.

Wherein, this cooling structure also includes master mold cold water jacket 107, is located at the hot filling nozzle in described mother module core 102 Around 108；Described master mold cold water jacket 107 is near described male die core 101 and mother module core 102 binding site；From And can effectively cool down die center and hot filling nozzle 108, shortening forming time.

Wherein, there is the 3rd seal groove and the 4th seal groove around this master mold cold water jacket 107, described It is provided with the 3rd sealing ring 109 in three seal grooves, in described 4th seal groove, be provided with the 4th sealing ring 110, The internal diameter of described 3rd sealing ring 109 is more than the internal diameter of described 4th sealing ring 110.

Compared to prior art, utilize cooling structure in the mould of the present invention, due to described mother module core 102 Hot filling nozzle 108 is provided around described master mold cold water jacket 107, such that it is able to reach cooling effect effectively, shortens Molding time, improves production efficiency；Due to described cold water jacket 104 near described die center and Described taper pin or thimble 103 position, can effectively cool down die center and described taper pin or thimble 103, shorten into The type time.

It is noted that the invention is not restricted to above-mentioned embodiment, any those skilled in the art's base Any simple modification, equivalent variations and the modification made above-described embodiment in technical solution of the present invention, all falls Enter in protection scope of the present invention.
