Abstract

The utility model discloses a foaming mould. The foaming mould comprises a female die and a male die; each of the female die and the male die consists of a core, a core installing plate and a back plate; a plurality of support rods are arranged between each core and the back plate and between each core installing plate and the back plate respectively; and the cross section of each support rod has a shape of hexagram. According to the foaming mould, the cross section of each support rod has the shape of hexagram; compared with the support rods which have the shape of the common hexagram, the support rods which have the shape of hexagram have the advantages that support intensity can be provided to the maximum extent under the condition of the same section area; and under the condition of the same support intensity, the using amount of materials is reduced, and the cost is low.

Description

Foaming molding mold

Technical field

The utility model belongs to the injection molding technology field, is specifically related to a kind of foaming molding mold.

Background technology

Foaming molding mold (foaming mould) claim plastic foaming mould again, and its foaming principle is: the foaminess resin is directly inserted in the mould cavity, in the outside vaporium of die cavity, charged into high-temperature steam; Make the foaminess resin melted by heating in the die cavity; Form the gas-liquid saturated solution,, form a large amount of small complexs through nucleation; Complex increases, and processes the foam plastic.

Foaming molding mold comprises die and punch, and during the moulding foaming, die and punch combine.The concave, convex mould is made up of core, core installing plate and backboard separately, and core is installed on the core installing plate.For the concave, convex mould that makes mould becomes as a whole respectively, when moulding, obtain reliable supporting intensity, be equipped with the complex root support bar between core and the backboard and between core installing plate and the backboard.

With die shown in Figure 1 is example, present foaming molding mold between core and the backboard and the cross section of the support bar that is provided with between core installing plate and the backboard be regular hexagon, reliable supporting intensity is provided when moulding.But under the identical situation of sectional area, orthohexagonal profile is not maximum in all geometric figures, can not maximizedly provide support intensity; On the other hand, under the identical situation of support strength, orthohexagonal sectional area is not minimum in all geometric figures, and material usage is more, and cost is high.

For solving the problems of the technologies described above, need provide a kind of and have under the identical situation of sectional area the maximized intensity that provides support; Under the identical situation of support strength, material usage reduces, the foaming mould of the support bar that cost reduces.

Summary of the invention

The utility model purpose provides a kind of foaming molding mold, through architecture advances, and under the identical situation of sectional area, the maximized intensity that provides support; Under the identical situation of support strength, material usage reduces, and cost reduces.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of foaming molding mold; Comprise die and punch; Said concave, convex mould is made up of core, core installing plate and backboard separately, is equipped with the complex root support bar between said core and the backboard and between said core installing plate and the backboard, and the cross section of said support bar is a hexagram.

In the technique scheme, offer centre bore on the said support bar.

Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:

1. the cross section of the support bar of the utility model is a hexagram, compare with regular hexagon commonly used, and under the identical situation of sectional area, the maximized intensity that provides support; Under the identical situation of support strength, material usage reduces, and cost reduces.

Description of drawings

Fig. 1 is the structural representation of die in the background technology;

Fig. 2 is the structural representation of die among the utility model embodiment one;

Fig. 3 is the vertical view of support bar among the embodiment one;

Wherein: 1, core; 2, core installing plate; 3, backboard; 4, support bar.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment one: referring to Fig. 2 and shown in Figure 3; A kind of foaming molding mold; Comprise die and punch, said concave, convex mould is made up of core 1, core installing plate 2 and backboard 3 separately, is equipped with complex root support bar 4 between said core 1 and the backboard 3 and between said core installing plate 2 and the backboard 3; The cross section of said support bar 4 is a hexagram, and offers centre bore on the support bar 4.

Through said structure, the cross section of support bar is a hexagram, compare with regular hexagon, and under the identical situation of sectional area, the maximized intensity that provides support; Under the identical situation of support strength, material usage reduces, and cost reduces.

Claims (2)

1. foaming molding mold; Comprise die and punch; Said concave, convex mould is made up of core (1), core installing plate (2) and backboard (3) separately; Be equipped with complex root support bar (4) between said core (1) and the backboard (3) and between said core installing plate (2) and the backboard (3), it is characterized in that: the cross section of said support bar (4) is a hexagram.

2. foaming molding mold according to claim 1 is characterized in that: said support bar offers centre bore on (4).
