Abstract

The utility model discloses a car sun visor mold which comprises an upper mold (1) and a lower mold (2), wherein a side slide block (3) is arranged on the corresponding position of one side of the lower mold (2). The car sun visor mold is characterized in that a support block (4) is arranged under the long and thin convex part of the lower mold (2), and the support block (4) can move up and down; and the support block is additionally arranged on the long and thin convex part formed on the lower mold, so that the strength of the mold is increased, the long and thin convex structure of the mold is protected from being bent or cracked, and further, the service life of the mold is increased, the production cost is reduced and the product quality is stabilized.

Description

A kind of automobile sun-shading board mold

Technical field:

The utility model relates to technical field of mold, is a kind of automobile sun-shading board mold specifically.

Background technology:

Development along with automobile industry; The sunshading board of vehicle dormer window also develops towards low cost, light weight and the high direction of intensity; So occurred the sunshading board product of kinds of processes at present; The sunshading board product of PHC, PP glass plate technology is light weight mostly, and for intensity and the product profile tolerance that guarantees sunshading board, turnup structure is mostly adopted in the product structure moulding of its front end (700mm left and right sides length).And the mould of this series products is too poor in the mould molding bossing intensity of product flange shape, has a strong impact on the service life of mould.

In the sunshading board compression molding process, at first the base material heating expand into certain thickness (being close to more than 1.5 times of product thickness), is sent in the mould by conveyer belt, and mold descends, and molded product is to the shape and the thickness of design.The bed die bulge-structure bears very big pressure owing to pushing base material in this process; Its thin and long structure is easy to bend even rupture; Afterwards slide block advance the action accomplishing the product flange and cut off can not regular event, can't realize the compression molding of this infrastructure product.

Present this kind constructed products, all adopted the product front end to launch compression molding mostly after, post bake flange position utilizes frock to carry out the technology of flanged edge making.But this kind technology directly causes equipment to have high input, and operation is many and efficient is low, problems such as the outward appearance of product and poor stability.

Summary of the invention:

The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, and a kind of automobile sun-shading board mold is provided, and mainly solves existing sunshading board mould molding bossing intensity difference and the flexible even problems such as influencing service life that ruptures.

In order to achieve the above object; The utility model is achieved in that a kind of automobile sun-shading board mold; It comprises mold and bed die; Side slide block is established in position in that bed die one side is corresponding, and its special character is that the length of described bed die and the below of thin boss establish back-up block, and back-up block can move up and down; Back-up block is up, can the support protrusion position, and prevent to carry in the mold pressing and be out of shape; Back-up block is descending, can reserve the running space of side slide block.

Compared with present technology the described a kind of automobile sun-shading board mold of the utility model has following good effect: owing to increased back-up block at the long and thin bossing of bed die moulding; Thereby increased the intensity of mould; Protected the long and thin bulge-structure of mould can crooked even fracture; Thereby increased the life-span of mould, reduced production cost, stabilized product quality.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and specify a kind of automobile sun-shading board mold of the utility model.

Embodiment 1, referring to Fig. 3, according to product specification Design and Machining mold 1, bed die 2 and side slide block 3; Side slide block 3 is corresponding with the position level of bed die 2; Side slide block 3 can move horizontally, and below the length of bed die 2 and thin boss, back-up block 4 is installed, and back-up block 4 can move up and down; The length of back-up block 4 and bed die 2 and thin boss are corresponding, need not fit like a glove; Back-up block 4 is up, can the support protrusion position, and prevent to carry in the mold pressing and be out of shape; Back-up block 4 is descending, can reserve the running space of side slide block 3.

The described a kind of automobile sun-shading board mold of the utility model, its operation principle are sent to (see figure 3) on the mould referring to Fig. 3,4,5,6 after base material 5 heating; Before mold 1 decline mold pressing base material 5; On bed die 2, increased the back-up block 4 that rises, back-up block 4 and bed die 2 length and thin boss applying (see figure 4) can play good support, humidification during mold pressing; Thereby protected the long and thin boss of bed die 2 can crooked even fracture; The back-up block 4 of bed die 2 drops to the initial position (see figure 5) after the mold pressing, and side slide block 3 moves ahead smoothly, accomplishes the flange structure of product and cuts off the product (see figure 6).

Claims

1. automobile sun-shading board mold; It comprises mold (1) and bed die (2); Side slide block (3) is established in position in that bed die (2) one sides are corresponding; It is characterized in that the length of described bed die (2) and the below of thin boss establish back-up block (4), back-up block (4) can move up and down.
