Description

Mould parting technology for special-shaped glass fiber reinforced plastic product

Technical Field

The utility model relates to a technical field of shaped glass steel processing auxiliary device especially relates to a mould divides mould technique for shaped glass steel product.

Background

As is well known, glass fiber reinforced plastic materials are increasingly used in the railway passenger car industry due to their characteristics of light weight, stable structure, impact resistance, corrosion resistance, and the like.

In order to meet the requirements of design, use and the like of customer products, part of glass fiber reinforced plastic products are designed into special-shaped pieces, and in the production process, the special-shaped pieces with certain specific structures have the following problems: due to the special structural design of some special-shaped glass fiber reinforced plastic products, after pasting and curing on a die body (as shown in figure 4), negative angle interference exists during demolding (as shown in figure 5), so that demolding cannot be carried out.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a mould divides mould technique for shaped glass steel product through change mould design technology, at the interference position of mould, divide into two parts with the mould to realize the complete drawing of patterns of product.

The utility model discloses a mould divides mould technique for shaped glass steel product, including the mould body, the mould body includes first mould and second mould, and the junction of first mould and second mould all is provided with the mould turn-ups, and two sets of the mould turn-ups passes through multiunit bolted connection.

The utility model discloses a dysmorphism mould parting technique for glass steel product, first mould and second mould seam crossing are handled through smooth transition.

Compared with the prior art, the beneficial effects of the utility model are that: the mould is divided into the mould structural design, the manufacture of the mould is simple and feasible, the mould copying period is shortened, the production efficiency of the product is improved, the structural design of the special-shaped glass fiber reinforced plastic product is not required to be changed, the integrity of the special-shaped glass fiber reinforced plastic product is ensured, the appearance integrity, the high strength, the excellent stability and the like of the product are ensured, the design and use requirements of customers are met, the daily maintenance cost is greatly reduced, the service life of the part is prolonged, meanwhile, the device conforms to the design concept of safety, economy, high efficiency and attractiveness of a railway passenger car, and the overall quality of the glass fiber reinforced plastic product is improved.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1 to 5, the mold splitting technology for the shaped glass fiber reinforced plastic product of the present invention comprises a mold body, wherein the mold body comprises a first mold 1 and a second mold 2, mold flanges are arranged at the joints of the first mold 1 and the second mold 2, and two sets of mold flanges are connected through a plurality of sets of bolts; the joint of the first die and the second die is defined as a parting surface, the parting surface is arranged at the maximum projection edge part of the demoulding direction of the electrical cabinet coaming product, namely, the glass fiber reinforced plastic part can be taken out from the die body, meanwhile, the parting surface meets the requirement of the demoulding axial degree direction, two parts of the parting are just divided into two vertical axis directions at the parting surface position, so that respective demoulding is facilitated, after the parting surface is selected, a die flanging is added at the joint of the first die 1 and the second die 2 of the parting, and the first die 1 and the second die 2 are connected by adopting a bolt, so that the first die 1 and the second die 2 are convenient to disassemble and assemble in a connecting mode, therefore, after the electrical cabinet coaming product is pasted and solidified, the bolt is removed, the second die 2 is firstly removed along the transverse direction, and then the first die 1 is separated from the product along the longitudinal direction, thereby realizing the complete and nondestructive demoulding of the product.

The utility model discloses a mould parting technique for special-shaped glass fiber reinforced plastic products, the joint of a first mould 1 and a second mould 2 is processed by smooth transition; the appearance of electrical cabinet bounding wall is not influenced to split mould face department, has avoided the convex-concave position on the mould, and the seam crossing of first mould 1 and second mould 2 is through smooth transition processing, can not cause the influence to the surface of product.

The utility model discloses a mould die parting technique for special-shaped glass steel product, it is at work, first mould and second mould junction definition are the parting face, the parting face position has been established at the biggest projection edge position of electrical apparatus cabinet bounding wall product drawing of patterns direction, can make glass steel spare take out from the mould body, simultaneously, this parting face satisfies drawing of patterns axiality direction requirement, two parts of parting are just divided into two vertical axis directions at the parting face position, do benefit to drawing of patterns respectively, after the parting face selection is accomplished, increase the mould turn-ups in the first mould 1 of parting and second mould 2 seam crossing, and adopt bolted connection, the mode of connection makes the dismantlement and the equipment of first mould 1 and second mould 2 convenient like this, therefore, after the electrical apparatus cabinet bounding wall product is pasted and is solidified, remove the bolt, drop second mould 2 along transversely earlier, then break away from the product along vertically with first mould 1, thereby realize the complete harmless drawing of patterns of product, die parting face department does not influence the outward appearance of electrical apparatus cabinet bounding wall, has avoided the convex-concave position on the mould, and the seam crossing of first mould 1 and second mould 2 is through smooth transition processing, can not cause the influence to the surface of product.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
