Abstract

The utility model discloses an injection mould which comprises a female mould, a male mould and a jacking mechanism, wherein the male mould is vertically and correspondingly matched with the female mould and is open or closed. The female mould comprises a female mould plate and a female mould core fixed below the female mould plate, the male mould comprises a male mould plate and a male mould core fixed above the male mould plate, the jacking mechanism comprises a pressing rod and an elastic element, the pressing rod is vertically and slidably mounted in the female mould core, and the elastic element is placed in the female mould plate. By the aid of the design of the jacking mechanism, the injection mould is opened at two stages, so that a product is separated from the female mould and then separated from the pressing rod of the jacking mechanism, deformation of the product due to excessive pulling force of the female mould in mould opening is avoided, and the yield of the product is improved.

Description

Injection mold

Technical field

The utility model relates to a kind of mould, particularly relates to a kind of injection mold.

Background technology

The various tool and the product that are used in daily production, the life have confidential relation with mould invariably, and most consumer goods all are plastic cement products, and this product forms out through injection mold.Injection mold before is when the processing plastic product, and the plastic cement after normally will melting waters and casts from the mould, and the cooling back demoulding to be formed just can obtain needed product.When the comparatively complicated product of moulding shape; Corresponding structure need be set on injection mold; Moulding one product 200 (as shown in Figure 3) for example, this product 200 is provided with position, a hole 202 near edge, and this position, hole 202 need moulding on the master mold of injection mold.

For example the said goods 200 is being owing to be provided with position, a hole 202 near edge, and then injection mold is can Yin Lali when die sinking excessive and make the part generation buckling deformation of product terminal 201 outside the position, hole 202 of product 200, increases the fraction defective of product.

The utility model content

The purpose of the utility model is that the deficiency to above-mentioned prior art provides a kind of excessive and injection mold that product is deformed of pulling force when preventing die sinking.

The utility model provides a kind of injection mold, comprise a master mold, one and master mold up and down corresponding matching be the male model and a top-pressure mechanism of die sinking or matched moulds.Master mold comprises that a caster and is fixed in the mother module core of caster below; The caster lower surface upwards offers a containing hole; The mother module core upper surface offers the spacing hole that is connected with containing hole downwards; The mother module core lower surface upwards offers the sliding eye that is connected with spacing hole, and the mother module core lower surface convexes with forming part downwards, and forming part is positioned at the sliding eye inboard; Male model comprises that a male model plate and is fixed in the male model benevolence of male model plate top; This top-pressure mechanism comprises a depression bar and a flexible member, and in the sliding eye that is installed in mother module core that depression bar can slide up and down, the depression bar upper end has a holding section; The holding section can slide up and down and is installed in the spacing hole of mother module core; The depression bar lower surface upwards is concaved with a gap, and gap and mother module core and male model benevolence surround a die cavity, and flexible member is placed in the containing hole of caster; The upper end is resisted against the containing hole inner bottom part, and the lower end presses on the holding section upper surface.

In sum; The utility model injection mold relies on the design of top-pressure mechanism; Make die sinking be divided into two stages completion; Thereby break away from the depression bar of top-pressure mechanism again after product and master mold are broken away from, and then avoid when die sinking improving the yield of product thus because of the excessive product that makes of master mold pulling force deforms.

The specific embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.

See also Fig. 1, the utility model injection mold 100 comprises a master mold 1, one and the male model 2 and a top-pressure mechanism (indicating among the figure) of master mold corresponding matching about in the of 1.

Master mold 1 comprises that a caster 11 and is fixed in the mother module core 12 of caster 11 belows.Caster 11 lower surfaces upwards offer a containing hole 111, and mother module core 12 upper surfaces offer the spacing hole 121 that is connected with containing hole 111 downwards, and the aperture of spacing hole 121 is greater than the aperture of containing hole 111.Mother module core 12 lower surfaces upwards offer the sliding eye 122 that is connected with spacing hole 121, and the aperture of sliding eye 122 is less than the aperture of spacing hole 121, and mother module core 12 lower surfaces convex with forming part 123 downwards, and forming part 123 is positioned at sliding eye 122 inboards.

Male model 2 and master mold about in the of 1 corresponding matching be die sinking or matched moulds, comprise that a male model plate 21 and is fixed in the male model benevolence 22 of male model plate 21 tops.

Top-pressure mechanism comprises a depression bar 31 and a flexible member 32.In the sliding eye that is installed in mother module core 12 122 that depression bar 31 can slide up and down, depression bar 31 upper ends have a holding section 311, and holding section 311 can slide up and down in the spacing hole 121 that is installed in mother module core 12.Depression bar 31 lower surfaces upwards are concaved with a gap 312, and gap 312 surrounds a die cavity (figure does not show) with mother module core 12 and male model benevolence 22.Flexible member 32 is placed in the containing hole 111 of caster 11, and the upper end is resisted against containing hole 111 inner bottom parts, and the lower end presses on holding section 311 upper surfaces.In the present embodiment, flexible member 32 is a spring.

See also Fig. 1; The utility model injection mold 100 is when the matched moulds state; Master mold 1 and male model 2 closures; Depression bar 31 lower ends of top-pressure mechanism are resisted against male model benevolence 22 upper surfaces, and depression bar 31 is contained in the sliding eye 122 of mother module core 12 fully, and holding section 311 upper surfaces of depression bar 31 are resisted against caster 11 lower surfaces.Holding section 311 is contained in flexible member 32 compressions in the containing hole 111 with caster 11.

See also Fig. 2 and Fig. 3; The 100 die sinking phase I of the utility model injection mold; Master mold 1 relative male model 2 moves upward; The flexible member 32 of top-pressure mechanism produces a downforce by compressive state in the process that nature is recovered, make depression bar 31 lower ends the product terminal 201 of product 200 continued to be pressed on the upper surface of male model benevolence 22.

See also Fig. 4, the utility model injection mold 100 die sinking second stage, master mold 1 relative male model 2 continues to move upward; Cause flexible member 32 to leave depression bar 311; When the holding section 311 of depression bar 31 slided into spacing hole 121 bottoms downwards with respect to mother module core 12, master mold 1 drove depression bar 31 and moves upward with respect to male model 2 together, thereby when product 200 is broken away from mother module core 12; Depression bar 31 lower ends still press on the product terminal 201 of product 200; After treating that mother module core 12 breaks away from the position, hole 202 of product 200, depression bar 31 breaks away from the product end 201 of product 200 again, so far accomplishes the demoulding of product 200.

In sum; The utility model injection mold 100 relies on the design of top-pressure mechanism; Make die sinking be divided into two stages completion; Thereby break away from the depression bar 31 of top-pressure mechanism again after product 200 and master mold 1 are broken away from, and then avoid when die sinking improving the yield of product 200 thus because of the excessive product 200 that makes of master mold 1 pulling force deforms.
