Description

Silica gel brush forming die

Technical Field

The utility model relates to the technical field of mold, concretely relates to silica gel brush forming die.

Background

The silica gel brush is in production forming process, need with inside the silica gel injection mould, wait to open the mould after the silica gel cooling shaping, it can to take out the silica gel brush.

However, in the process of injecting silica gel, the existing silica gel brush forming die cannot discharge air due to the fact that air exists in the cavity, the injected silica gel and the air in the cavity are extruded, and the silica gel cannot be conveyed to the top of the cavity, so that the formed silica gel brush head is incomplete, the forming quality of the silica gel brush is affected, the processing efficiency is reduced, material waste is caused, and the production cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a silica gel brush forming die in order to solve the above-mentioned problem.

The utility model achieves the purpose through the following technical scheme, and the silica gel brush forming die comprises a structure main body, wherein the structure main body comprises an upper template, a middle template and a lower template which are arranged in sequence; the upper template is provided with a plurality of groups of brush head mold cores and top flash tanks, the brush head mold cores are positioned at the inner side of the upper template, and the top flash tanks penetrate through the upper template; the middle template is provided with a plurality of groups of brush head forming grooves and a middle flash groove, and the middle flash groove penetrates through the middle template; the lower template is provided with a plurality of groups of silica gel brush skirt edge forming grooves, and the silica gel brush skirt edge forming grooves are formed in the inner side of the lower template.

Preferably, the plurality of groups of brush head mold cores and the top flash tanks are distributed on the upper template in a staggered manner.

Preferably, the plurality of groups of brush head forming grooves and the middle flash grooves are distributed on the middle template in a staggered manner.

Preferably, the top flash tanks correspond to the middle flash tanks one by one.

Preferably, the brush head mold core, the brush head forming groove and the silica gel brush skirt forming groove correspond to each other.

Preferably, the upper template, the middle template and the lower template are provided with an upper positioning through hole, a middle positioning through hole and a lower positioning through hole which are correspondingly distributed.

The beneficial effects of the utility model are that: through the setting of middle part flash tank and top flash tank, play the effect of the unnecessary silica gel of discharge, back in the silica gel injection mold, the air in the die cavity is extruded by silica gel, through the discharge of shaping groove surface, unnecessary silica gel is discharged through the shaping groove, discharges from middle part flash tank and top flash tank for silica gel gets into the die cavity completely, avoids appearing the incomplete condition of brush head shaping, has improved the shaping quality.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-4: the silica gel brush forming die in the embodiment comprises an upper template 3, a middle template 2 and a lower template 1 which are sequentially arranged; a plurality of groups of brush head mold cores 11 and top flash tanks 7 are arranged on the upper template 3, the brush head mold cores 11 are positioned at the inner side of the upper template 3, and the top flash tanks 7 penetrate through the upper template 3; a plurality of groups of brush head forming grooves 4 and middle flash tanks 6 are arranged on the middle template 2, and the middle flash tanks 6 penetrate through the middle template 2; the lower template 1 is provided with a plurality of groups of silica gel brush skirt edge forming grooves 5, and the silica gel brush skirt edge forming grooves 5 are formed in the inner side of the lower template 1.

Wherein, a plurality of groups of brush head mould cores 11 and top flash chutes 7 are distributed on the upper template 3 in a staggered way; a plurality of groups of the brush head forming grooves 4 and the middle flash grooves 6 are distributed on the middle template 2 in a staggered manner; the top flash tanks 7 correspond to the middle flash tanks 6 one by one; the brush head mold core 11, the brush head forming groove 4 and the silica gel brush skirt edge forming groove 5 correspond to each other; the upper template 3, the middle template 2 and the lower template 1 are provided with an upper positioning through hole 8, a middle positioning through hole 10 and a lower positioning through hole 9 which are correspondingly distributed.

It should be noted that the top flash tank 7 corresponds to the middle flash tank 6.
