The existing soft mould is generally cut into a plurality of pieces by adopting a natural rubber plate, and then the pieces are bonded and formed by using glue, and due to the bonding and forming, the shape of each transition part of the barrel is inaccurate, the protruding angle of the pressed blank is easy to damage, and due to the fact that the blank is easy to bend because the rubber is very soft, the column body is provided with the dent generated by the crease of the rubber barrel, and therefore, the blank needs to be turned to a large part to produce products conforming to the size.
The utility model comprises the following steps:
the utility model provides a novel insulator isostatic pressing soft die for solving the problems in the prior art.
The utility model adopts the technical scheme that:
the novel isostatic compaction soft die for the insulator comprises a barrel body and a cover cap, wherein the barrel body and the cover cap are integrally molded by casting polyurethane materials, the barrel body is of an upper end opening and lower end closing type structure, the cover cap is covered on the barrel body and closes an upper port of the barrel body, a binding belt is arranged on the outer wall surface of the cover cap, and the barrel body and the cover cap are fixed by the binding belt; the outer wall surface of the upper port of the barrel body is provided with a convex rib which protrudes outwards, and the inner wall of the cap is provided with an assembly groove which is matched with the convex rib.
Further, a binding groove is formed in the outer wall of the cap, and the binding belt is bound in the binding groove.
Further, a turned-out edge which is turned outwards and is arranged along the axial direction of the barrel body is arranged at the barrel opening of the barrel body, and a hanging groove is formed between the inner wall surface of the turned-out edge and the outer wall surface of the barrel body.
Further, at least two convex ribs are arranged and layered on the outer wall surface of the flanging.
Further, the strapping slot is located between two of the fitting recesses.
The utility model has the following beneficial effects:
1) According to the utility model, the polyurethane material is selected as the rubber barrel (namely the barrel body and the cap) aiming at the defects of the traditional soft mold, the hardness of the polyurethane material is higher than that of natural rubber, and the defects of bending crease pits and the like in compression molding can be avoided. Compared with natural rubber, the polyurethane material has better oil resistance and fatigue resistance, can greatly prolong the service life of the soft mold, save materials and reduce cost.
2) In addition, the barrel body and the cap are integrally molded through casting, the end face angle of the cylindrical barrel can be made into an accurate chamfer angle and a round angle, and the conditions of corner falling, breakage and the like in the pressing process are avoided.
3) Be equipped with the assembly recess and the protruding muscle that are used for the assembly between staving and block, guarantee the cooperation effect, guarantee the leakproofness, tie up the groove and be located between two wherein assembly recesses, bind behind the tie up the groove at the tie up, make protruding muscle and recess can combine inseparabler.
Description of the drawings:
fig. 1 is a structural diagram of the present utility model.
Fig. 2 is a structural view of the tub.
Fig. 3 is a structural view of the cap.
The specific embodiment is as follows:
the utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the novel isostatic compaction soft mould for the insulator comprises a barrel body 1 and a cap 2, wherein the barrel body 1 and the cap 2 are integrally molded by casting polyurethane materials, and the barrel body 1 is of a closed structure with an open upper end and a closed lower end. The cap 2 is covered on the barrel body 1 and seals the upper port of the barrel body 1. The outer wall surface of the cap 2 is provided with a binding belt which fixes the barrel body 1 and the cap 2.
In order to ensure the matching effect between the barrel body 1 and the cap 2 and the tightness, the outer wall surface of the upper port of the barrel body 1 is provided with convex ribs 11 which are outwards protruded, the convex ribs 11 are at least provided with two, and the convex ribs are arranged on the outer wall surface of the flanging 12 in a layering way.
