Description
Technical Field
The utility model relates to a mould specifically is a split type mould.
Background
When the composite material vacuum infusion process is used for preparing large-scale complex parts, the composite material vacuum infusion process becomes the first choice in the industries of wind driven generators, luxury yachts and the like at present due to the characteristics of convenient manufacture, short manufacturing period and the like of the mold.
When complex parts are prepared, the mold is often disassembled to achieve demolding. The split mold forms a split mold, and the two split molds need to be matched to realize complete part production.
The problem generally faced by the industry at present is that when the split mold is made of glass fiber reinforced plastics, one split mold needs to be fixed on the other split mold by means of external tools such as a clamp, and when the glass fibers are layered, one split mold can generate displacement relative to the other split mold under the influence of external force; meanwhile, the vacuum infusion process needs to ensure the sealing of the mold, so that the clamp has to be taken down when the whole mold is sealed, and the clamp is fixed again after being coated with a vacuum bag, so that the two split molds generate larger displacement, and the appearance and the size of a product are influenced finally.
SUMMERY OF THE UTILITY MODEL
For overcoming one of the above-mentioned defect or the defect of current split mould, the utility model discloses a novel split mould, the technical scheme who takes is:
a split type die comprises split bodies which can be sequentially butted and combined, parting surfaces of adjacent split bodies horizontally extend towards two sides to form flanges, annular grooves are respectively formed in the flanges on two sides of one split body, and annular sealing strips are embedded in the annular grooves; and the flanges at two sides of one split body within the range corresponding to the annular groove are provided with a vacuumizing port with an opening on the parting surface of the split body, and the vacuumizing port is connected with one end of a vacuum tube.
Further, the other end of the vacuum tube is connected with a vacuum pump or a vacuum buffer tank.
Further, a vacuum valve is mounted on the vacuum tube.
Furthermore, more than 1 positioning pin is fixedly arranged on the flanges at two sides of one split body respectively, and correspondingly, more than 1 positioning hole which is in splicing fit with the positioning pin is arranged on the flanges at two sides of the other split body which is in butt joint combination with the split body respectively; when the positioning hole corresponds to the annular groove, the positioning hole is a blind hole.
Compared with the prior art, the utility model discloses need not the cladding vacuum bag, need not take off repeatedly and centre gripping anchor clamps, saved a large amount of manual operation time.

Detailed Description
The present invention will be further described with reference to the accompanying drawings by taking a split mold having an upper split body and a lower split body as an example.
A split mold as shown in fig. 1 to 5, comprising an upper split 1 and a lower split 2, wherein:
go up components of a whole that can function independently 1 and locate to both sides horizontal extension formation upper flange 11 at its lower die joint, go up the upper flange 11 of both sides and form 2 locating pins 12 from lower die joint downwardly extending respectively, and locating pin 12 cross-section is the fillet rectangle, wholly is big-end-up's wedge post.
The lower split body 2 horizontally extends to two sides from the upper parting surface to form a lower flange 21, the lower flanges 21 on the two sides respectively extend downwards from the upper parting surface to form 2 positioning holes 22 corresponding to the positioning pins 12, the cross section of each positioning hole 22 is a rounded rectangle, the lower end of each positioning hole is closed, and the whole positioning hole is a wedge-shaped groove with a large upper part and a small lower part; the lower flanges 21 on two sides of the lower split body 2 extend downwards from the upper parting surface to form annular grooves 23 respectively, the annular grooves 23 are integrally in a round corner rectangle shape, the two annular grooves 23 enclose the 2 positioning holes 22 respectively, an annular sealing strip 3 is embedded in each annular groove 23, the upper edge of each annular sealing strip 3 protrudes out of the upper parting surface, and when the upper split body 1 and the lower split body 2 are in butt joint combination, the lower surface of the upper flange 11 of the upper split body 1 abuts against the upper edge of each annular sealing strip 3 to realize sealing; the lower flanges 21 on the two sides are respectively fixedly provided with a vacuum-pumping port 24, and the upper end opening of the vacuum-pumping port 24 is positioned on the upper parting surface and is positioned in the range of the annular groove 23; the lower end of the vacuum-pumping port 24 is connected with one end of a vacuum tube 4, the other end of the vacuum tube 4 is connected with the vacuum buffer tank 5, and a vacuum valve is arranged in the middle of the vacuum tube 4 and used for controlling whether the area in the annular sealing strip 3 is vacuumized or not, and the vacuum valve is not shown in the figure.
The support positioning points are respectively arranged on the upper split body 1 and the lower split body 2, so that when the support is used for moving the upper split body 1 and the lower split body 2, the split die can be prevented from being damaged in the transportation and storage processes, and meanwhile, the storage space of the split die is saved.
When the mold is used, the upper split body 1 and the lower split body 2 are hoisted by the hoisting support, the positioning is carried out through the positioning pin and the positioning hole, the vacuumizing valve is opened, a vacuum sealing space is formed between the upper split body 1 and the lower split body 2, and the upper split body 1 and the lower split body 2 are butted, combined and fixed into the mold with the cuboid cavity. Because the vacuum tube is connected on the vacuum storage tank, the pressure maintaining of the mold is realized, so that the stable vacuum pressure is ensured to be maintained between the upper split body 1 and the lower split body 2, the vacuum bag does not need to be coated, the clamp does not need to be repeatedly taken down and clamped, and a large amount of manual operation time is saved.
