In the design of the top liner hot-pressing die structure, the guide mechanism, the design for parallel embedded oil passages and the design for a water-cutting positioning structure are combined, so that the top liner hot-pressing die structure has the technical advantages that the manual operation for forming is convenient, the oil temperature for forming is even, the cycle for forming is short, the accurate positioning for the follow-up water-cutting processing is ensured and the like.

Description

A kind of roof liner hot pressing die structure

Technical field

The utility model relates to automobile manufacturing field, relates in particular to a kind of roof liner hot pressing die structure.

Background technology

The hot pressing die that is used for the automobile roof liner moulding at present; Structure is comparatively complicated, and forming process oil temperature is uneven, and roof liner is because of sheet forming characteristics-bounce-back; And not corresponding location; Problems such as product can not meet design requirement after being prone to cause moulding, and follow-up water cutting technique location is inaccurate make the roof liner product percent of pass low.

The utility model content

In order to solve roof liner hot pressing die complex structure of the prior art, manually-operated is complicated, and molding cycle is long; The temperature control of process oil is uneven, the inaccurate problem in water cutting location, and the utility model provides a kind of roof liner hot pressing die structure; The counterdie Renhe upper cores that comprises mutual butt joint; Said counterdie Renhe upper cores connects through lock module, comprises that also one of them that be arranged in said die down or the upper cores is provided with guide pillar, and wherein another in said die down or the upper cores is provided with the guide pin bushing that cooperates with guide pillar; Also comprise the bridging pin, said bridging pin is arranged on said die down or upper cores outside through hinge means.

As the further improvement of the utility model, also comprise lower limit post and upper limit post, be provided with the adjusting pad in the middle of lower limit post and the upper limit post.Lower limit post and upper limit post are used to control accurately spacing when hot-forming, auxiliary guide pillar guide pin bushing jointly.

As the further improvement of the utility model, said counterdie Renhe upper cores is one-time formed die.

As the further improvement of the utility model, said lock module is at least four, is evenly distributed on said die 2 and upper cores 3 joints down.

As the further improvement of the utility model, said guide pillar and guide pin bushing are equally distributed at least four.

As the further improvement of the utility model, said counterdie Renhe upper cores set inside parallel connection oil circuit, said parallelly connected oil circuit comprises two inlets and two imports.

As the further improvement of the utility model, said die down is provided with water cutting reference column, and said water cutting reference column is for being arranged on four jiaos of mould insides.The water cutting technique location that is used for roof liner part after the moulding can guarantee water cutting accurate positioning, and processing puts in place.

The beneficial effect of the utility model is: it is even that the utility model roof liner hot pressing die is simple in structure, oil pipe buries cloth, easy to operate, and accurate positioning guarantees that subsequent product water cutting technique puts in place.

Guiding mechanism, parallelly connected pre-buried oil circuit design among the design, water cutting location structure composite design realization moulding manually-operated is convenient, the oily temperature of moulding is even, technical advantages such as molding cycle is short, the accurate positioning of the follow-up water cutting technique of assurance.

The specific embodiment

Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.

A kind of roof liner hot pressing die structure comprises the following die 2 and upper cores 3 of mutual butt joint, and said die 2 down is one-time formed die with upper cores 3.Said die 2 down is connected through lock module 4 with upper cores 3, and said lock module 4 is at least four, is evenly distributed on said die 2 and upper cores 3 joints down.Comprise that also one of them that be arranged in said down die 2 or the upper cores 3 is provided with guide pillar 5, wherein another in said die 2 down or the upper cores 3 is provided with the guide pin bushing 6 that cooperates with guide pillar 5, and said guide pillar 5 and guide pin bushing 6 are equally distributed at least four.Also comprise bridging pin 9, said bridging pin 9 is arranged on said die 2 or upper cores 3 outsides down through hinge means 10.Also comprise lower limit post 7 and upper limit post 13, lower limit post 7 is regulated pad 8 with upper limit post 13 middle being provided with.

Said die 2 down is provided with water cutting reference column 14, and said water cutting reference column is positioned at four jiaos of mould insides.

Said die 2 down and upper cores 3 set inside parallel connection oil circuit, said parallelly connected oil circuit comprises two inlets and two imports.

The utility model structure is mainly used in the automobile roof liner wet moulding, this hot pressing die structure such as Fig. 1 and Fig. 2, and die adopts casting aluminium material up and down; One-shot forming, guiding mechanism and detent mechanism are simple, guarantee that the moulding manually-operated is convenient; Designed the bridging pin; The location that is used for the preceding lining of moulding, lining is pullled in the cancellation manual work, guarantees that operation is convenient and shortens molding cycle;
