Abstract

The invention provides a multivalve elbow mold. The multivalve elbow mold comprises an elbow inner core assembly, an elbow soft sleeve, carrying dies and rotating supporting rods; the elbow inner core assembly comprises more than two elbow inner cores, the elbow inner cores are connected with one another through chains, and every two adjacent elbow inner cores are positioned through a pin key; the elbow soft sleeve covers the elbow inner core assembly; two bearing dies are respectively fixed on two ends of a die body which is formed by the elbow inner core assembly and the elbow soft sleeve; one rotating supporting rod is fixed on a top cover of each carrying die, and each rotating supporting rod is positioned on an extension line of a rotating central line of the die body. The multivalve elbow mold has the advantages that the convenience in mold stripping can be achieved, and the production efficiency can be improved; when the two ends of a product are respectively provided with a bell mouth with large diameter, the product can be integrally formed; the weight of the mold is light, so that the mold is convenient to move and assemble.

Description

The multi-clove type elbow module

Technical field

The present invention relates to a kind of multi-clove type elbow module.

Background technology

Traditional glass reinforced plastic elbow die is the expansion type overall structure, at the intrados of elbow the wide arc seam of b=10 ~ 20mm is arranged, the swollen bar of filling between the arc seam.

During the demoulding, take off first the swollen bar in the arc seam, make mold shrinkage, take off again product.

Because the contact-making surface of mould and product is large, often the demoulding is difficult.

When two ends were the larger bellmouth of diameter, unitary mould can't the demoulding, and product can not global formation, needed after the respectively moulding hand to stick with paste docking again.

Summary of the invention

The technical problem to be solved in the present invention is traditional glass reinforced plastic elbow die demoulding difficulty, when two ends are the larger bellmouth of diameter, unitary mould can't the demoulding, product can not global formation.

For solving the problems of the technologies described above, the technical solution used in the present invention is: the multi-clove type elbow module comprises elbow inner core group, elbow mantle cover, holds mould, rotary support bar; Described elbow inner core group comprises the elbow inner core more than two, connects by chain between the elbow inner core, and adjacent elbow inner core is located by pin key; The outer illiteracy on elbow inner core group of described elbow mantle cover; Two are held the two ends that mould is separately fixed at the die body that is combined into by elbow inner core group and elbow mantle cover; Each holds on the top cover of mould and fixes a rotary support bar, and the rotary support bar is positioned on the extended line of rotation centerline of die body.

The elbow die body is divided into some assembling parts forms, not only make mold weight lighter, be convenient to the carrying assembling, and solved the shortcoming of traditional glass steel elbow module demoulding time and effort consuming; When the elbow two ends were the larger bellmouth of diameter, unitary mould can't the demoulding, the defective that product can not global formation.

As a kind of improvement project of the present invention, the two ends of described mould can respectively add and hold mould, hold mould by dismountable screw mandrel connecting bend inner core group, and described screw mandrel one end holds mould by the nut connection, the other end is connected and fixed elbow inner core group, and described swivel bearing bar is fixed on the top cover that holds mould.

Advantage of the present invention is: be convenient to the demoulding, enhance productivity; When two ends are the larger bellmouth of diameter, but the product global formation; Mold weight is lighter, is convenient to the carrying assembling.

Fig. 2 is that Figure 1A-A is to cutaway view.

Fig. 3 is structural representation of the present invention.

The specific embodiment

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, traditional glass reinforced plastic elbow die is the expansion type overall structure, comprises elbow die body 1 and rotary support bar 2, at the intrados of elbow die body 1 the wide arc seam of b=10 ~ 20mm is arranged, the swollen bar 3 of filling between the arc seam.

During the demoulding, take off first the swollen bar 3 in the arc seam, make mold shrinkage, take off again product.

As shown in Figure 3, the present invention includes elbow inner core group, elbow mantle cover 6, hold mould 4, rotary support bar 2; Described elbow inner core group comprises the elbow inner core 5 more than two, connects by single strand chain 7 between the elbow inner core 5, and adjacent elbow inner core 5 is by pin key 8 location; Described elbow mantle overlaps 6 outer illiteracies on elbow inner core group; Two are held mould 4 is fixed on respectively elbow inner core group by dismountable screw mandrel 9 two ends, and described screw mandrel one end is connected and fixed by nut 10 and holds mould 4, and the other end is connected and fixed elbow inner core group; Be to improve fixed effect, nut 10 and hold between the top cover of mould 4 and also be pressed with pad, increasing friction, each holds an affixed rotary support bar 2 on the top cover of mould 4, and rotary support bar 2 is positioned on the extended line of rotation centerline of die body.

The mould assembling:

Single strand chain 7 is penetrated between elbow inner core 5, each elbow inner core 5 is coupled together;

To hold on the elbow inner core group after mould 4 is contained in combination with screw mandrel 9;

Tighten screw mandrel 9, single strand chain 7 is tightened;

Cover with elbow mantle cover 6.

The mould dismounting:

The nut 10 of releasing lever 9 takes off pull bar 9 and holds mould 4;

Pulling single strand chain 7 takes off each elbow inner core 5;

Take out elbow mantle cover 6.

Claims
