Automotive upholstery production injection mold
Technical field
The utility model relates to automotive upholstery production field, particularly a kind of automotive upholstery production injection mold.
Background technology
By film transmitting machine, figuratum for print film is delivered between fixed half and moving half.After matched moulds, fixed half and moving half, by film clamp, vacuumizes die cavity, film and die cavity inwall is fitted, then carries out injection moulding.After injection moulding completes, pattern and thin film separation, and the technology being transferred to that plastic surface forms decoration, be injection surface decoration technique (hereinafter referred to as IMD technology).IMD technology is rely on injection mo(u)lding, realizes injection mo(u)lding and decoration integrated, is widely used in the production of automotive upholstery.But after dynamic model and cover half matched moulds, very easily there is the phenomenons such as wrinkling, cracking in the film in die cavity, directly affects pattern transferring effect, thus have influence on the decorative effect of automotive upholstery, reduce the quality of automotive upholstery.The wrinkling situation of film is serious, even can make the surface irregularity of final obtained automotive upholstery, depart from design shape originally, cause product rejection.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of automotive upholstery production injection mold avoiding film wrinkling.
For realizing above object, the utility model is achieved through the following technical solutions:
Automotive upholstery production injection mold, comprises fixed half and moving half; It is characterized in that, also comprise press box; Described press box between described cover half and described dynamic model, can near or arrange away from described cover half.
Preferably, at least one briquetting is also comprised; Described briquetting is arranged on described press box, is oppositely arranged with described cover half; Described briquetting protrudes the surface of described press box, and moves relative to described press box; After movement, described briquetting embeds in described press box.
Preferably, described press box is provided with the groove adapted with described briquetting; Described briquetting can embed in described groove.
Preferably, at least two briquettings are comprised; Described at least two briquettings are arranged at least two frames of described press box.
Preferably, at least one Compress Spring is provided with between each described briquetting and described press box; Described Compress Spring one end is against described briquetting; The other end is against described press box.
Preferably, described briquetting and described press box are respectively equipped with the first slot and the second slot that adapt with described Compress Spring; The two ends of described Compress Spring are inserted in the first slot and the second slot respectively.
Preferably, two Compress Springs are provided with between each described briquetting and described press box.
Preferably, each described briquetting is connected with described press box is removable by screw.
Preferably, described press box is provided with through hole; Described briquetting is provided with screwed hole; One end of described screw and described screwed hole threaded engagement; The other end of described screw is arranged in described through hole movably, and is provided with boss; The inwall of described through hole is provided with step, is blocked in described through hole by described boss.
Preferably, described cover half is provided with guide post; Described guide post runs through described press box and described dynamic model; Described press box and described dynamic model can along described guide post near or away from described cover half.
The automotive upholstery production injection mold that the utility model provides, the film after dynamic model and cover half matched moulds in die cavity can be effectively avoided to occur the phenomenons such as wrinkling, cracking, thus avoid the decorative effect of pattern transferring effect and automotive upholstery to be adversely affected, ensure that the high-quality of automotive upholstery.Also the profile of automotive upholstery can be avoided simultaneously to depart from design shape originally, avoid product rejection.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in figures 1 to 6, automotive upholstery production injection mold comprises cover half 1, dynamic model 2 and press box 3.Press box 3 is between cover half 1 and dynamic model 2.Cover half 1 is provided with guide post 8, and guide post 8 runs through dynamic model 2 and press box 3.Dynamic model 2 and briquetting 3 can along guide post 8 near or away from cover half 1.
Automotive upholstery production injection mold also comprises two briquettings 4.Each briquetting 4 is equipped with two screwed holes 41, and two frames be oppositely arranged 31 of press box 3 are respectively equipped with two through holes 32.Be threaded with briquetting 4 by the screwed hole 41 that briquetting 4 is inserted in the lower end of screw 5, upper end is arranged in through hole 32 movably, briquetting 4 is arranged on press box 3 movably, and is oppositely arranged with cover half 1.The upper end of screw 5 is provided with boss 51, and the inwall of through hole 32 is provided with step 33, and boss 51 is blocked in through hole 32 by step 33, avoids screw 5 to be separated with press box 3.
Two Compress Springs 6 are also provided with between each briquetting 4 and press box 3.Briquetting 4 and press box 3 are respectively equipped with the first slot 42 and the second slot 34 adapted with Compress Spring 6.The two ends of Compress Spring 6 are inserted in the first slot 42 and the second slot 34 respectively.Briquetting 4 is supported by Compress Spring 6, protrudes the surface of press box 3.Press box 3 is provided with the groove 35 adapted with briquetting 4.Pressed by external force briquetting 4, Compress Spring 6 compresses, and briquetting 4 finally embeds in groove 33.
The using method of automotive upholstery production injection mold is as follows:
Film feeding---as shown in Figure 1, cover half 1 and dynamic model 2 die sinking, press box 3 does not contact with cover half 1.Figuratum for print film 9 is delivered between cover half 1 and press box 3.
Press mold---mobile press box 3, makes press box 3 close to cover half 1.To be oppositely arranged with cover half 1 and the briquetting 4 protruding press box 3 surface first contacts with the region that creases easily on film 9.Press box 3 continues near cover half 1, and Compress Spring 6 compresses, and produces elastic force, briquetting 4 by this elastic force by the region that creases easily on film 9 by being pressed on cover half 1.Press box 3 continues near cover half 1, and treat that briquetting 4 embeds in groove 35 completely, press box 3 contacts with film 9, by its four frames 31 by film 9 by being pressed on cover half 1.Effectively prevent by briquetting 4 region generation fold that film 9 creases easily, thus avoid the decorative effect of pattern transferring effect and automotive upholstery to be adversely affected, ensure that the high-quality of automotive upholstery.Also the profile of automotive upholstery can be avoided simultaneously to depart from design shape originally, avoid product rejection.
Matched moulds---dynamic model 2 and cover half 1 closed (as shown in Figure 3), and carry out the operations such as follow-up thin film deep drawing, injection moulding, make the pattern on film 9 be transferred to plastic surface.
Die sinking---dynamic model 2 and cover half 1 are opened, and mobile press box 3 is separated with film 9.Take out plastic.So far a life cycle is completed.
Upper and lower in the present embodiment is all reference with Fig. 1, more clearly describes the relative concept that the utility model uses, does not form the restriction to right.
Embodiment in the utility model, only for being described the utility model, does not form the restriction to right, other equivalent in fact substituting, all in the utility model protection domain that those skilled in that art can expect.
