Abstract

The utility model discloses a forming mould for U-shaped bending pieces. The forming mould comprises an upper mould plate, a lower mould plate, a guiding component, a male mould, a female mould, and an unloading plate, and is characterized in that a groove is formed at the upper part of the lower mould plate; the dimension of the inner chamber of the groove is in accordance with the dimension of a part; the width of a groove is the width of the splitted blocks of the female mould; and the female mould adopting a splitting structure is embedded in the groove of the lower mould plate with 5mm embedded depth. The utility model has the advantages of easy assembly and simple structure; by adopting the structure that the female mould is embedded in the groove, error in forming dimension can be reduced and the forming dimension precision can be ensured; and as the forming mould adopts the manner of fixing on four sides, lateral forces can be compensated, and the forming mould is durable.

Description

U type bending part mould

Technical field

The utility model relates to a kind of mould, especially relates to a kind of U type bending part mould that is used for white domestic appliances.

Background technology

In daily life, white domestic appliances are seen everywhere, and U type bending part is usually arranged in the white domestic appliances, but the forming parts size that has is bigger, generally about 1650mm * 300mm * 30mm, in manufacturing process size and surface state thereof are all had relatively high expectations, therefore the mould design for this kind part also has higher difficulty, especially molding procedure.For the bigger part of this type of compact dimensions, there is following drawback in the manufacturing of tradition mould: 1, mould generally adopts the piece structure, but in the piece process, has bigger scale error, especially easily the parallelogram phenomenon occurs, the mould assembly difficulty is big; 2, mould is offset side force with pin, but in the long-term production process, makes pin distortion or fracture easily, causes accessory size inaccurate.

The utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of forming parts scale error that makes little, and mould is easy to assemble, U type bending part mould simple in structure.

The utility model is achieved through the following technical solutions:

A kind of U type bending part mould comprises cope match-plate pattern, lower bolster, guidance set, punch, die, stripper, it is characterized in that: groove is formed at the top of described lower bolster, die is the piece structure, is embedded in the groove of lower bolster, and insert depth is 5mm.

The inner cavity size of described groove is consistent with accessory size, and width is the width of cavity splits.

The beneficial effects of the utility model are: the utility model is easy to assembling, simple in structure, employing die embedding groove structure, can subdue the error of compact dimensions, guarantee the precision of compact dimensions, because employing is the fixing mode in four sides, can offset side force, durable in use.

Description of drawings

Fig. 1 is the structural representation of U type bending part mould described in the utility model;

Fig. 2 is the A portion enlarged drawing of Fig. 1.

Main Reference numeral implication is among the figure:

1, die 2, lower bolster 3, cope match-plate pattern 4, punch 5, stripper 6 guiding parts

The specific embodiment

Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:

Fig. 1 is the structural representation of U type bending part mould described in the utility model; Fig. 2 is the A portion enlarged drawing of Fig. 1.

As depicted in figs. 1 and 2: a kind of U type bending part mould, comprise cope match-plate pattern 3, lower bolster 2, guidance set 6, punch 4, die 1, stripper 5, it is characterized in that: groove is formed at the top of described lower bolster 2, die 1 is the piece structure, in the groove of masterplate 2, insert depth is 5mm. under being embedded into

The inner cavity size of described groove is consistent with accessory size, and width is the width of die 1 piece.

In assembling process, at first mill and process groove on the top of lower bolster 2, the die 1 that will have the piece structure is embedded in the above-mentioned groove, according to lower bolster 2 assembling punch 4, guarantees that finally the size of whole mould is accurate again.

Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.

Claims

1. a U type bending part mould comprises cope match-plate pattern, lower bolster, guidance set, punch, die, and stripper is characterized in that: groove is formed at the top of described lower bolster, and die is the piece structure, is embedded in the groove of following masterplate.

2. U type bending part mould according to claim 1 is characterized in that the inner cavity size of described groove is consistent with accessory size.
