Abstract
The invention relates to a locating mechanism of an automobile acoustic component punching die. A locating nail base is fixed to the upper surface of a lower die carrier. An installation hole is formed in the locating nail base in the length direction of the locating nail base. A locating nail is inserted in the installation hole of the locating nail base in a sliding mode. A pin is inserted in the lower end of the locating nail. A spring is installed in the installation hole of the locating nail base. The upper end of the spring abuts against the lower end face of the locating nail and the lower end of the spring abuts against the upper surface of the lower die carrier. A pin slide way is formed in the locating nail base in the length direction of the locating nail base. The pin is installed in the pin slide way in a sliding mode. A locating recessed portion matched with the top end of the locating nail is formed in the lower surface of an upper die carrier. The locating mechanism is simple, compact and reasonable in structure, the locating nail is combined with a product, the problem existing in locating cooperation of two dies is solved, locating accuracy of a semi-finished product in the following working procedure is improved, product quality is improved, scraped products are reduced, and resource waste of raw materials and each link is reduced.
Description
Technical field
The present invention relates to a kind of detent mechanism of using on follow-up die-cut, the laminating class mould of the automotive upholstery products such as automobile ceiling, sunshading board product of being applicable to, the present invention especially relates to a kind of detent mechanism of acoustic part of automobile die cutting die, the invention belongs to automobile die technical field.
Background technology
At present, many automotive upholstery products are taked two-step method moulding process in process of production, i.e. first precompressed substrate forming, then be positioned in laminating mould, carry out the laminating of fabric or first carry out after formed product, then be positioned over carrying out on die cutting die product clout die-cut.In this type of process of producing product, two secondary moulds become most important for the location of product.In semi-finished product forming process, locating pin is installed on mould, so that semi-finished product can accurately locate in next procedure, but after semi-finished product moulding, often has larger distortion (as: product perk etc.), when semi-finished product are positioned on rear road mould, product often can not accurately be located.Cause two secondary mould location to coordinate the upper larger problem that exists, make semi-finished product in later process, have low precision, product quality is low, causes large-tonnage product to scrap simultaneously, causes raw material and the links wasting of resources.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can the in the situation that of deformation of products, accurately locate, make semi-finished product in later process, accurately locate, improve product quality, reduce product rejection and can reduce the detent mechanism of the acoustic part of automobile die cutting die of raw material and the links wasting of resources.
According to technical scheme provided by the invention, the detent mechanism of described acoustic part of automobile die cutting die, comprise top mold frame and lower mold holder, upper surface at lower mold holder is fixed with locating pin base, in locating pin base, along its length direction, offer installing hole, in the installing hole of locating pin base, sliding plug has locating pin, bottom in locating pin is plugged with latch, in the installing hole of locating pin base, spring is installed, the upper end of spring and the lower surface of locating pin offset, the bottom of spring and the upper surface of lower mold holder offset, on locating pin base, along its length direction, offer latch slideway, described latch is slidably mounted in latch slideway, lower surface in top mold frame offers the location depression coordinating with locating pin top ends.
The length of described latch slideway is 40 ~ 80mm, and latch slideway is long kidney-shaped hole.
The upper surface of described locating pin is hemisphere face.
The present invention is simple in structure, compact, reasonable, locating pin is combined with product, not only solve two secondary mould location and coordinated the upper problem existing, increased semi-finished product accurate positioning in later process, improved product quality, reduce product rejection, reduced raw material and the links wasting of resources.

The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
The detent mechanism of this acoustic part of automobile die cutting die, comprise top mold frame 6 and lower mold holder 1, upper surface at lower mold holder 1 is fixed with locating pin base 2, in locating pin base 2, along its length direction, offer installing hole, in the installing hole of locating pin base 2, sliding plug has locating pin 5, it is characterized in that: in the bottom of locating pin 5, be plugged with latch 4, spring 3 is installed in the installing hole of locating pin base 2, the lower surface of the upper end of spring 3 and locating pin 5 offsets, the upper surface of the bottom of spring 3 and lower mold holder 1 offsets, on locating pin base 2, along its length direction, offer latch slideway 8, described latch 4 is slidably mounted in latch slideway 8, lower surface in top mold frame 6 offers the location depression 7 coordinating with locating pin 5 top ends.
The length of described latch slideway 8 is 40 ~ 80mm, and latch slideway 8 is long kidney-shaped hole.
The upper surface of described locating pin 5 is hemisphere face.
Described locating pin base 2 is fixed on lower mold holder 1 by bolt and alignment pin, spring 3 is positioned in locating pin base 2, locating pin 5 is made pin hole, and locating pin 5 is positioned in locating pin base 2, and by latch 4, locating pin base 2 and locating pin 5 is mounted to this detent mechanism.
The course of work of the present invention is:
Top mold frame 6 is individually fixed in the upper and lower platform in press with lower mold holder 1, and after die sinking, product is positioned on lower mold holder 1, and the location depression 7 of product pre-molding is embedded mutually with the locating pin 5 of later process mould.Press sends instruction, top mold frame 6 moves downward with press upper mounting plate, 7 contact products cave in location in top mold frame 6, in descending process, locating pin 5 also compresses product orientation with location depression 7, and move downward thereupon, correcting product in the process pressing down, makes product can be good at fitting in lower mould profile, makes accurately carrying out of later process.After completing, press sends instruction, and top mold frame 6 moves upward with press upper mounting plate, and the spring 3 in locating pin base 2 resets, and realizes locating pin 5 and resets.
