Problems solved by technology

There are certain defects in this production method, because the columnar upper body and the arched lower body are made of two pieces of wet cardboard respectively, and the characteristics of the product cannot be glued together, so it is difficult to combine the transition rounded corners well, and it is easy to delaminate after drying Cracking, resulting in unqualified product quality

Embodiment 1

[0019] Such as figure 1 and figure 2 Commonly shown, a wet forming device for insulating special-shaped parts, including: a mandrel 1 for special-shaped parts and an elastic force applying device. The special-shaped mandrel 1 includes a columnar mandrel 11 and an arched mandrel 12, the columnar mandrel 11 is arranged on the radial direction of the arc surface of the arched mandrel 12, the junction of the columnar mandrel 11 and the arched mandrel 12 It is a rounded transition surface 13; the elastic force applying device includes a force applying plate 21 and a special-shaped piece pressing plate 22 which are arranged oppositely. The arc surface of the mandrel 12 is matched, and the through hole 3 for fitting the cylindrical mandrel 11 is opened on the pressure plate 22 of the special-shaped part. A force applying spring 4 is arranged between the piece pressing plates 22, and the force applying spring 4 is sleeved on the stud 5, and the stud 5 is threadedly connected with t...

Embodiment 2

[0022] Such as image 3 and Figure 4 Commonly shown, a wet forming device for insulating special-shaped parts, its structure is basically the same as that of Embodiment 1, the difference is that an annular elastic body 7 is provided between the special-shaped part pressing plate 22 and the rounded transition surface 13, and the corresponding , the edge of the through hole 3 is provided with a cavity 8 for accommodating the annular elastic body 7, by means of the contraction and expansion of the annular elastic body 7, the wet cardboard layer between the special-shaped piece pressing plate and the fillet transition surface 13 can be more effectively The combination is good, the elastic deformation of the annular elastic body 7 changes with the thickness of the product during the drying process, the applied force is more uniform, and the compressed state is always maintained to ensure the product quality. The shape of the two end surfaces 9 of the cavity 8 located on the speci...

Abstract

The invention discloses an insulating irregular part wet method forming device which comprises an irregular part core mold and an elastic forcing device, wherein the irregular part core mold comprises a cylindrical core mold and an arched core mold, the cylindrical core mold is arranged in the radial direction of an arc surface of the arched core mold, the combination part of the cylindrical core mold and the arched core mold is a fillet transition surface, the elastic forcing device comprises a forcing plate and an irregular part pressure plate which are oppositely arranged, the forcing plate is fixedly installed at the end of the cylindrical core mold, the irregular part pressure plate is provided with an arc surface matched with the arched core mold and a through hole for being sleeved with the cylindrical core mold, the edge of the through hole is adapted to a shape of the fillet transition surface, and a forcing spring is arranged between the forcing plate and the irregular part pressure plate. According to the insulating irregular part wet method forming device disclosed by the invention, the transition part of an upper body and a lower body is good to combine, so that the qualified rate of a product is increased.

Description

technical field [0001] The invention relates to the technical field of molds for insulating shaped parts, in particular to a wet forming device for insulating shaped parts. Background technique [0002] There are many types of insulating special-shaped parts, among which a large number of special-shaped parts are composed of the lower body of the arched surface and the upper body of the hollow column. At present, when making such special-shaped parts, the insulating wet cardboard is first wrapped in the cylindrical core. mold and arched mandrel, then hand-pat and roll the wet cardboard, paste the wet cardboard evenly on the mold, then vacuum dehydrate, wrap the elastic band and put it into the oven to dry and shape, and finally put the mold and the dried The special-shaped parts are separated, and then refined to obtain the finished insulating special-shaped parts. There are certain defects in this production method, because the columnar upper body and the arched lower body...
