Technical Field

The utility model relates to the field of bicycle manufacturing, in particular to a high-gloss inner wall carbon fiber bicycle frame forming die.

Background

Carbon fiber bicycle frames have been popular in recent years because of their light weight, high strength, corrosion resistance, etc., and in the process of manufacturing carbon fiber bicycle frames, the interior space of the frames is molded by a mold as shown in fig. 1, for example, in chinese patent application: the application number 2017107163338, the name of which is a bicycle frame and an integrated forming manufacturing method thereof disclose that an EPS mould is used for forming the inner space of a frame girder, and the EPS mould finds the following defects in the use process: firstly, the inner wall of a product frame produced by the die is rough, wrinkles, glue accumulation or glue shortage are easy to generate sand holes, and secondly, the rigidity, strength and stability of the die are gradually deteriorated in the use process, so that the die is difficult to demould.

Disclosure of Invention

Aiming at the defects in the prior art, the technical problem to be solved by the utility model is how to improve the die structure to enable the inner wall of the produced frame to be smooth and to be capable of stably and rapidly demoulding, and the specific technical scheme is as follows:

a molding die for a bicycle frame with a high-gloss inner wall and carbon fibers comprises a die body with a split structure, wherein the outer side of the die body is coated with a high-gloss film.

As a preferable scheme of the utility model, the die body is made of high-tearing-resistance silica gel.

As a preferable scheme of the utility model, the die body is formed by split assembly of two triangular sections.

As a preferable scheme of the utility model, the die body is formed by split assembly of two split bodies with square sections.

As a preferable scheme of the utility model, the die body is formed by split assembly of two split bodies with trapezoidal sections.

As a preferable scheme of the utility model, the two ends of the die body are provided with the convex pieces which are convenient for demoulding.

As a preferred embodiment of the present utility model, the protruding member is a screw.

As a preferable embodiment of the present utility model, the high-gloss film is a high-temperature-resistant high-gloss film.

The beneficial effects are that: the outside cladding of mould body has the highlight membrane, ensures that the internal face of shaping frame is smooth, not wrinkled, and the convenient drawing of patterns of the mould body of components of a whole that can function independently structure moreover, and the mould body adopts high anti tearing silica gel to make, can not break when moving back the mould, complete separation, and the practicality is strong.

Detailed Description

The following describes the embodiments of the present utility model further with reference to the accompanying drawings:

in the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the positions or elements referred to must have specific directions, be configured and operated in specific directions, and thus should not be construed as limiting the present utility model.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood as appropriate by those of ordinary skill in the art.

As shown in fig. 2 and 3, embodiment one: the utility model provides a highlight inner wall carbon fiber bicycle frame forming die, includes the mould body 1 of split type structure, and the cladding of mould body 1 outside has the highlight membrane, and mould body 1 adopts high tear-resistant silica gel to make, and mould body 1 is assembled by the components of a whole that can function independently of two cross-sections for triangle-shaped.

As shown in fig. 4, embodiment two: the utility model provides a highlight inner wall carbon fiber bicycle frame forming die, includes the mould body 1 of split type structure, and the cladding of mould body 1 outside has the highlight membrane, and mould body 1 is assembled by the components of a whole that can function independently that two cross-sections are square.

As shown in fig. 5, embodiment three: the utility model provides a highlight inner wall carbon fiber bicycle frame forming die, includes the mould body 1 of split type structure, and the cladding of mould body 1 outside has the highlight membrane, and mould body 1 is assembled by the components of a whole that can function independently of two cross-sections for trapezoidal.

Specifically, in all the above embodiments, the two ends of the die body are provided with the protruding parts 2 which are convenient for demolding, the protruding parts 2 are screws, the high-tear-resistance silica gel is coated with the screws during molding, and the high-gloss film is a high-temperature-resistant high-gloss film which can not be melted during molding.
