Description

TYPE C split structure and forming method thereof

Technical Field

The invention belongs to the field of TYPE C connectors, and particularly relates to a TYPE C split structure.

Background

The outer mold of TYPE C connector is mostly holistic external mold structure, adopts the mould shaping to set up on the centre form in the connector outside, but in the forming process, the easy unsaturated mould of appearance of holistic external mold one shot forming and surface shrink or decorative pattern scheduling problem, causes these bad reasons mainly be in the forming process, and the centre form can't carry out effectual fixing.

The connector structure with the structure has extremely low external mold forming yield, causes the defects of the whole product to reach more than 50 percent, causes great waste, and greatly increases the production cost of enterprises.

Disclosure of Invention

The invention aims to solve the problems and provides a TYPE C split structure, which adopts a sectional TYPE external mold structure design, and secondary molding, wherein in the molding process, the internal mold is easy to fix, effective fixation can be formed, the external mold is high in molding yield, the product yield is improved, and the production cost of enterprises is greatly reduced.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a TYPE C components of a whole that can function independently structure, includes connector, centre form, first shaping external mold and second shaping external mold, and the centre form sets up in the connector outside, and first shaping external mold mould shaping is in centre form outside front end, and second shaping external mold secondary die shaping is in centre form outside rear end.

Furthermore, the front end of the connector is also provided with a front plug.

In the molding method of the TYPE C split structure, the outer mold adopts a mold molding process, specifically, a secondary molding mode is adopted during molding, a first position mold is fixed on the connector during the first molding, a second position mold is fixed on the inner mold at the rear end, a third position mold at the rear end wire is fixed at the same time, and then the first molding outer mold is molded;

after molding, the mold at the second position is switched to be fixed to a fourth position which is located outside the first molding outer mold, and then molding of the second molding outer mold is performed.

In summary, the invention has the following advantages:

the invention provides a TYPE C split structure, which adopts a sectional TYPE external mold structure design, and secondary molding, wherein in the molding process, the internal mold is easy to fix, effective fixation can be formed, the external mold has high yield, the product yield is improved, and the production cost of an enterprise is greatly reduced.

FIG. 2 is a schematic view of the first mold fixing position of the outer mold;

FIG. 3 is a schematic view of the second overmold fixation position.

Detailed Description

The invention is further described with reference to the following figures and examples:

example 1:

a TYPE C split structure is shown in figure 1 and comprises a connector 1, an inner die 2, a first forming outer die 3, a second forming outer die 4 and a front plug 5 at the front end of the connector 1.

The inner die 2 is arranged on the outer side of the connector 1, the first forming outer die 3 is formed at the front end of the outer side of the inner die 2, and the second forming outer die 4 is formed at the rear end of the outer side of the inner die 2.

According to the molding scheme of the TYPE C split structure, a mold molding process is adopted, a secondary segmented molding method is adopted, segmented fixation is carried out in the segmented molding process, and effective fixation of the inner mold in the molding process is effectively guaranteed, so that the molding effect of the outer mold is guaranteed.

Specifically, referring to fig. 2, in the first molding, the connector is subjected to a first position 100 for mold fixing, and the inner mold 2 is subjected to mold fixing at a rear end second position 200, and simultaneously, a third position 300 at the rear end wire 6 is subjected to mold fixing, and then the first molding outer mold 3 is molded.

After molding, the mold at the second position 200 is switched to be fixed to a fourth position 400, specifically referring to fig. 3, the fourth position 400 is located outside the first molding outer mold 3, specifically the first position and the third position are kept fixed in the mold, and molding of the second molding outer mold 4 is performed.

This secondary forming scheme adopts the fashioned mode of segmentation, carries out the segmentation fixed, utilizes the fashioned front and back order poor, with fixed position conversion between second position and fourth position, realizes the fixed knot structure in the mould of different stages to can effectively fix the position of centre form in the mould die cavity by the segmentation, make it can not appear the displacement of individual direction, overcome the not full mould of product external mold shaping or the problem of surperficial shrink/decorative pattern.

To sum up, this scheme adopts the external mold structural design of sectional type, and secondary forming, in the shaping process, the centre form is fixed easy, can form effectively fixedly, and the external mold shaping yields is high, improves the product yields, greatly reduced enterprise manufacturing cost.
