Description

Device is assembled in a kind of post forming precompressed

Technical field

The utility model belongs to car trim former, and in particular to device is assembled in a kind of post forming precompressed.

Background technology

Automobile decorative panel is typically the secondary injection molding method production being combined using ebonite and flexible glue, due to its strip The characteristics of, when an ebonite is molded, having to fluctuate in terms of size has certain deformation and the margin of tolerance, is carrying out secondary flexible glue During injection, one-time formed ebonite product can not possibly be bonded completely with the mould of secondary injection molding.Conventional method：First by ebonite Product is put into mould, with hammer, hand pressure, the methods of, ebonite product is put into mould, the method can cause product bounce-back bending or Deformation, can produce leak adhesive when carrying out the injection of secondary flexible glue, the problems such as flexible glue skewness uniform edge damage, product qualification rate it is low and It is inefficient.

Utility model content

The purpose of this utility model is the post forming precompressed assemble mechanism for providing a kind of good forming effect.

Realize that the technical scheme that the utility model purpose uses is as follows：

Device is assembled in post forming precompressed provided by the utility model, including is respectively equipped with the preceding mould of die cavity, rear mold, also wraps Include hold-down mechanism, the die cavity direction along the rear mold that the hold-down mechanism includes before being hinged on mould sets and can be with Strip briquetting corresponding to the die cavity of the rear mold.

Locating slot is respectively equipped with the preceding mould and rear mold, the top and bottom of the strip briquetting are respectively equipped with and the preceding mould The locating piece coordinated with the locating slot in rear mold.

The bottom shape of the strip briquetting matches with being positioned over shape above the product of the rear model cavity.

The beneficial effects of the utility model

During post forming, using the utility model precompressed assemble device, can make one-time formed ebonite product with it is secondary The mould of injection molding is bonded completely, preferably solves that during secondary flexible glue injection leak adhesive, flexible glue skewness, edge damage can be produced The problems such as being rebounded with deformation of products, improve product qualification rate and production efficiency.

The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.

Embodiment

See Fig. 1, device is assembled in post forming precompressed provided by the utility model, including the preceding mould 1 with double-colored model cavity, Rear mold 2, in addition to the hold-down mechanism 3 being hinged on preceding mould 1, the preceding mould 1 are provided with quadric injection mould die cavity 101 and locating slot 102, the rear mold 2 is provided with the die cavity 201 and locating slot 202 of ebonite product, and the hold-down mechanism 3 includes one along rear mold 2 On the direction of die cavity 201 set and can strip briquetting 301 corresponding with the die cavity of rear mold, the both ends of strip briquetting 301 pass through Connecting plate 303 and support plate 101 before being fixed on mould 1 are be hinged, the top and bottom of strip briquetting 301 be respectively equipped with preceding mould 1 Locating piece 304,302, the bottom shape of strip briquetting 301 and placement corresponding to locating slot 202 on locating slot 102 and rear mold 2 Shape matches above ebonite product in die cavity 201.

Exemplified by producing car trim, application method of the present utility model is as follows：

1st, Fig. 2, Fig. 3 are seen, preceding mould 1 opens up, and the ABS bodies skeleton being molded in monochromatic mould is one-time formed ebonite Product a；Ebonite product a is inserted into the die cavity 201 in double-colored model cavity in rear mold 2, it can be seen that ebonite product a is not pasted completely The die cavity 201 of next mould 5；

2nd, see Fig. 2, Fig. 3, the strip briquetting 301 in hold-down mechanism 3 is rotated into 180 degree, the locating piece in strip briquetting 301 304 are engaged with the locating slot 102 on preceding mould 1, position strip briquetting 301；

3rd, Fig. 4, Fig. 5 are seen, preceding mould 1 is closed downwards, passes through the strip briquetting in injection machine mould assembling action hold-down mechanism 3 301 compress ebonite product a, and ebonite product a bottom fits like a glove with the die cavity 201 in rear mold 2, then open preceding mould 1, and will Hold-down mechanism 3 is by manual reversion original state, as shown in Figure 6；

4th, Fig. 7 is seen, matched moulds, the quadric injection mould die cavity 101 on molding anterior mold 1, then quadric injection mould, die sinking, ejection take out Finished product.Finished product bends or deformed as shown in figure 8, not producing product bounce-back, or produces leak adhesive when carrying out quadric injection mould, The problems such as flexible glue skewness uniform edge damage.

Claims (3)

1. device is assembled in a kind of post forming precompressed, including is respectively equipped with the preceding mould of die cavity, rear mold, it is characterized in that also including compressing Mechanism, the die cavity direction along the rear mold that the hold-down mechanism includes before being hinged on mould set and can with it is described after Strip briquetting corresponding to the die cavity of mould.
