Problems solved by technology

[0003]However, there are still obvious defects in its use: 1. The above-mentioned device cools the upper mold core by passing cold water from the water inlet pipe, Therefore, cooling water needs to be continuously fed and discharged during use, and the water consumption is large. Moreover, additional devices are required to store cold water before use and hot water after use. The equipment is cumbersome and the overall floor space is also large. ;2. After cooling, it is necessary to perform demoulding treatment. If the above device is used, it is impossible to know when the cooling is completed, and demoulding also requires manual assistance, which is inconvenient to use

Embodiment 1

[0032] An upper mold core for a low-pressure mold, comprising:

[0033] The main mold 1 is provided with an intermediate cavity 101, a side cavity 102, a horizontal cavity 103, an accommodating cavity 104 and a groove 105. 105 each has two, and symmetrically opened on both sides of the middle cavity 101, the inner wall of the middle cavity 101 is fixedly provided with an open box body 2, the open box body 2 is made of a material with good thermal conductivity, such as aluminum Alloy, pure copper, etc., the top of the open box body 2 is provided with an elastic gasket 3, the elastic gasket 3 has good ductility, such as heat-conducting rubber, etc., the open box body 2 and the elastic gasket 3 are surrounded by The cavities are filled with cooling liquid, which increases in volume when frozen and freezes, and decreases in volume after the ice cube melts. For example, in this embodiment, the cooling liquid can directly choose water, which is commonly used Easy to obtain and low ...

Embodiment 2

[0041] In this embodiment, on the basis of the first embodiment, the structure of "the end of the blocking block 8 away from the second spring 9 can be snapped and fixed in the transverse cavity 103" is further specifically defined: the blocking block 8 is far away from the second spring 9 An extension rod 10 is fixedly arranged at one end of the extension rod 10, a first raised portion 11 is fixedly arranged on the extension rod 10, a positioning frame 12 is fixedly arranged on the inner side wall of the transverse chamber 103, and a second raised portion 13 is fixedly arranged in the positioning frame 12 , the second protruding portion 13 can limit and fix the first protruding portion 11, and when in use, the blocking block 8 can be pushed toward the direction close to the positioning frame 12 until the first protruding portion 11 on the extension rod 10 When being limited by the second protrusion 13 in the positioning frame 12, the blocking block 8 at this time is relatively...

Embodiment 3

[0043] On the basis of Embodiment 1, this embodiment further specifically defines the buckle structure of "the pressing plate 18 can move up and down, and is snapped and fixed under the open box body 2": the upper part of the pressing plate 18 is fixed There is a clamping rod 19, the third protruding part 20 is fixedly arranged on the clamping rod 19, and the fourth protruding part 22 is fixedly provided on the inner wall of the groove 105, and the fourth protruding part 22 can carry out the third protruding part 20. The limit is fixed. When in use, the main mold 1 is lowered as a whole, and the pressure plate 18 will be restricted by the lower mold core below, and then passively pushed upward, so that the clamping rod 19 above the pressure plate 18 is inserted into the groove 105 until the first When the three protruding parts 20 are limited by the fourth protruding part 22, the pressing plate 18 at this time is fastened and fixed on the bottom of the open box body 2.

Abstract

The invention provides an upper mold core of a low-pressure mold and the low-pressure mold thereof, a cavity defined by an open box body and an elastic sealing gasket is filled with cooling liquid, a refrigeration sheet is embedded in the side, close to the elastic sealing gasket, of a transverse plate, and a first connecting rope is connected to the transverse plate; and the end, away from the transverse plate, of the first connecting rope is fixedly arranged on a stop block, and the bottom of a third spring is connected with a demolding rod. The pressing plate can move up and down and is fixed to the lower portion of the open type box body in a buckled mode, a refrigeration piece closing button is arranged at the top of the groove, when the demolding rod descends, the cleaning brush is pushed outwards through the transmission structure, and then the outlet end of the elastic telescopic pipe is cleaned and blocked. According to the upper mold core of the low-pressure mold and the low-pressure mold thereof, cooling liquid is arranged in the upper mold core, the upper mold core can be repeatedly used and is more convenient to use, automatic jacking and demolding can be achieved after cooling is finished, automatic cleaning and blocking prevention are achieved, the using effect is better, and the lower mold core is very worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of low-pressure molds, in particular to an upper mold core of a low-pressure mold and a low-pressure mold thereof. Background technique [0002] In the prior art, a water-cooled upper mold core with the publication number "CN108941510A" specifically relates to the technical field of casting molds, including an annular upper mold core body, a water-cooling mechanism and several air holes. V-shaped tube group, the inverted V-shaped tube group includes strip-shaped first water-cooled grooves and second water-cooled grooves arranged on the side wall of the upper mold core body, the bottom end of the first water-cooled groove intersects with the bottom end of the second water-cooled groove, The opening end of the first water-cooling groove of the inverted V-shaped tube group intersects the opening end of the second water-cooling groove of the adjacent inverted V-shaped tube group, and the intersection of several ...
