Description
Technical field
The present invention relates to a kind of sectional die.
Background technology
RTM is the abbreviation of resin transfer molding process, is a kind of technology adopting rigidity close die to manufacture composite.Its general principle is placed through appropriate design in the mold cavity designed in advance, to cut out or through the preformed reinforcing material of mechanization, after to be clamped and good seal mould, from the hole for injecting glue being arranged at appropriate location, the resin adhesive liquid prepared under uniform temperature and pressure is injected mould, make it to soak into reinforcing material, then heating makes composite material solidification, and finally demould obtains moulded products.RTM technique have production efficiency high, invest the series of advantages such as low, good work environment, energy consumption are low, Technological adaptability is strong, therefore gain great popularity, development rapidly, has been widely used in the fields such as building, traffic, telecommunication, health, Aeronautics and Astronautics.A kind of novel RTM mold disclosed in Chinese patent literature 201410294177.7, it comprises former and formpiston, the former L-type plate that former comprises former level board and is connected with former level board two ends, the formpiston L-type plate that formpiston comprises formpiston level board and is connected with formpiston level board two ends, the width of former level board is longer than the width of formpiston level board, formpiston level board is provided with gum-injecting port and bleeding point, the edge of former lower surface is provided with sealing joint strip along surrounding, sealing joint strip is compressible, the crossbeam of former L-type plate is provided with locating hole, the crossbeam of formpiston L-type plate is provided with the alignment pin matched with locating hole on former L-type plate, the crossbeam two ends of formpiston L-type plate are provided with the first screwed hole, sealing strip under the crossbeam of former L-type plate is provided with the second screwed hole closed with the first corresponding threaded holes, adjusting screw is successively through the first screwed hole and the second screwed hole, and contact with the crossbeam lower surface of former L-type plate, the other end of adjusting screw is connected with rocking bar, increased by pivots rocker in use or reduce the cavity thickness between former and formpiston, injecting glue speed is controlled with this, control product thickness and resin pocket etc., but, for large-sized resin transfer moulding goods, to ensure quality of item, metal die must be adopted, but metal die not easily manufactures, and expense costly, the series of products of particularly identical for shape and size difference (especially width dimensions is different), if manufacture multiple mould, cost is very high.
Summary of the invention
The object of this invention is to provide a kind of sectional die, the mold cavity width size being intended to solve RTM mold in prior art fixes the problem of brought poor universality.
In order to realize above object, in the present invention, the technical scheme of sectional die is as follows:
Sectional die, comprise first and second cover plate be oppositely arranged and the body be folded between first and second cover plate, the two ends of body are formed into die cavity by first and second cover plate shutoff respectively, first cover plate and/or the second cover plate offer the locating hole of fixed cover body position, locating hole has the distributed architecture corresponding with at least two kinds of different sizes and/or difform body on residing cover plate.
Body is surrounded with end to end direction around first and second cover plate relative direction by two or more coaming plate.
Locating hole corresponding to same body is annularly spaced apart and form centring ring on residing cover plate, and the centring ring that body not of the same race is corresponding respectively distributes along body spaced radial.
Body is the circle cover erected on residing cover plate, and residing for each centring ring, circumference on the cover board distributes with one heart.
Cover plate residing for locating hole offers the charging hole at the position, the center of circle being in circumference residing for centring ring.
First and second cover plate is provided with the fastening structure being clamped in body two ends in opposite directions.
Fastening structure have two or more and in the periphery of body circumferentially interval arrange.
Fastening structure comprises two dead rings fixed respectively or be wholely set on the edge of first and second cover plate and the fastening bolt be installed in two dead rings, and dead ring stretches out from the edge of residing cover plate, and described fastening bolt is installed in the extension of dead ring.
Locating hole offered by first cover plate, and on the first cover plate, offers the charging hole be in body, the second cover plate offers and is in spout hole in body and aspirating hole.
Be oppositely arranged in the present invention first, body is folded between the two by two cover plates, again by first, two cover plates are in the shutoff at body two ends, forming cavity is formed to be closed by the endoporus of body, in the process, body relies on the locating hole on the first cover plate and/or the second cover plate to carry out position and fixes, because this locating hole has the distributed architecture corresponding with at least two kinds of different sizes and/or difform body on residing cover plate, so for the situation of different forming cavity size or shape need, by selecting different bodies, again body is arranged on corresponding locating hole, realize the assembling of mould, the product of often kind of corresponding a kind of size of mould or shape compared to existing technology, in the present invention, the scope of application of mould is larger, adjust also convenient.
