Description

Saving type mould for vulcanization molding of silica gel

Technical Field

The utility model belongs to the technical field of the mould technique and specifically relates to indicate a saving type silica gel vulcanization mould utensil for shaping.

Background

The mould is used for obtaining various moulds and tools of required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother". Besides the die, the die also needs a die holder, a die frame and a die core to cause a finished piece ejection device and the like.

Most of the dies are divided into an upper die and a lower die, the upper die is positioned right above the lower die, and the upper die moves downwards and is matched with the lower die during forming. The existing mold for silica gel vulcanization molding mostly adopts a flat upper mold to carry out hot-pressing vulcanization molding on silica gel, but the flat upper mold is used for hot-pressing vulcanization molding on silica gel, so that the size of the formed silica gel is unstable, the shape of the formed silica gel is difficult to expect, the cut excess material is difficult to recycle, waste is caused, and the material consumption of the molding process is serious. Therefore, there is a need for an improvement of the existing mold for silica gel vulcanization molding.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a saving-type mold for silica gel vulcanization molding, which has a stable size of the molded silica gel and a predictable shape, and can easily recycle the cut excess material without waste.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a saving-type mould for vulcanizing and forming silica gel comprises a lower mould and an upper mould; the lower die comprises a lower die base, wherein the periphery of the surface of the lower die base is convexly provided with an outer frame, the outer frame is formed into a forming cavity in a surrounding way, and the bottom surface of the forming cavity is convexly provided with at least two bosses upwards; the upper die is movably arranged right above the lower die up and down, and is in a flat plate shape and matched with the forming cavity.

As a preferred scheme, the outer frame is provided with at least two forming grooves, the forming grooves are positioned beside the forming cavity and communicated with the forming cavity, and each forming groove is opposite to the corresponding boss.

Preferably, the depth of the forming cavity is deeper than that of the forming groove.

Preferably, the top end face of the boss is higher than the bottom face of the forming groove.

As a preferred scheme, the number of the bosses is four, and the four bosses are arranged in a 'field' shape.

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:

through the protruding frame that is equipped with of the surface periphery at the die holder, this frame encloses the configuration and becomes to have the shaping chamber, and the frame is spacing to silica gel, and the size and the shape of control shaping back silica gel cooperate again and are equipped with two at least bosss to the epirelief at the bottom face in shaping chamber, and the boss can control the thickness of shaping back silica gel clout, prevents too much materials, leads to leading to causing the waste of silica gel after cutting to, improve for one from one and produce more, improve production efficiency.

To illustrate the structural features and functions of the present invention more clearly, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

20. And (5) an upper die.

Detailed Description

Referring to fig. 1 to 3, a specific structure of a preferred embodiment of the present invention is shown, including a lower mold 10 and an upper mold 20.

The lower die 10 comprises a lower die base 11, an outer frame 12 is convexly arranged on the periphery of the surface of the lower die base 11, the outer frame 12 is formed into a forming cavity 13 in a surrounding mode, and at least two bosses 14 are convexly arranged on the bottom surface of the forming cavity 13 upwards; in this embodiment, the outer frame 12 is provided with at least two forming grooves 15, the forming grooves 15 are located beside the forming cavity 13 and are communicated with the forming cavity 13, and in addition, each forming groove 15 is opposite to the corresponding boss 14; the depth of the molding cavity 13 is deeper than that of the molding groove 15; the top end surface of the boss 14 is higher than the bottom surface of the forming groove 15; the number of the bosses 14 is four, and the four bosses 14 are arranged in a shape like a Chinese character 'tian'.

The upper mold 20 is movably disposed right above the lower mold 10, and the upper mold 20 is shaped like a flat plate and is adapted to the molding cavity 13.

Detailed description the manufacturing process of this embodiment is as follows:

firstly, a silica gel primary material needing hot pressing vulcanization is placed in the forming cavity 13, then the upper die 20 moves downwards, the silica gel primary material is hot pressing vulcanization formed, and then the formed silica gel is cut into a required specification.

The utility model discloses a design focus lies in: through the protruding frame that is equipped with of the surface periphery at the die holder, this frame encloses the configuration and becomes to have the shaping chamber, and the frame is spacing to silica gel, and the size and the shape of control shaping back silica gel cooperate again and are equipped with two at least bosss to the epirelief at the bottom face in shaping chamber, and the boss can control the thickness of shaping back silica gel clout, prevents too much materials, leads to leading to causing the waste of silica gel after cutting to, improve for one from one and produce more, improve production efficiency.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
