Description

Mould

Technical field

The utility model relates to mechanical field, relates in particular to a kind of mould.

Background technology

The product that our daily life is used much comes out through mould molding, and current mould is made up of mother module core, male model benevolence, slide block, guide pillar, thimble etc. usually, and this mould can the simple product of moulding.

Yet, when the shape of product of needs is special, want two holes of moulding such as an end of product; An inclination, one is straight, if use conventional molds; A slide block demoulding is moved and can only can not be satisfied an above-mentioned angling hole, the synchronous withdrawing pattern in a straight hole toward a direction.

Therefore, demand a kind of mould that can solve the problems of the technologies described above urgently, have the formed product of above-mentioned double-pore structure thereby accomplish smoothly.

The utility model content

The purpose of the utility model is to the deficiency of above-mentioned prior art a kind of mould to be provided, thereby realizes that an end has the smooth moulding of the product of angling hole peace straight hole.

To achieve these goals; The utility model provides a kind of mould, is used for moulding one side and has the angling hole of gradient and the product in straight straight hole, and it comprises mother module core, male model benevolence, slide block, gradient slide block, guide pillar and thimble; The upper surface of said slide block has a gradient; Said gradient slide block closely places the upper surface of said slide block, forms die cavity between said mother module core, male model benevolence, slide block, the gradient slide block, and said slide block has second pilot hole that connects self; The gradient slide block has first pilot hole that connects self; The diameter of said first pilot hole is greater than the diameter of said second pilot hole, and an end of said guide pillar is fixed on the said mother module core, and the other end is inserted in said first, second pilot hole; The axis of said second pilot hole is positioned at the side of the axis of said first pilot hole near die cavity during matched moulds; Thereby an end of the corresponding die cavity of said gradient slide block is the skewed product that makes and forms an angling hole in a corresponding end, and the gradient of said angling hole is identical with the gradient of the upper surface of said slide block, thereby the horizontal product that makes of an end of the corresponding die cavity of said slide block forms straight hole in a corresponding end; Said male model benevolence has the centre hole that is connected with said die cavity, and said thimble slidably is inserted in the said centre hole.

As stated; The utility model mould has slide block and gradient slide block, and the upper surface of said slide block has a gradient, and said gradient slide block places on the said slide block slidably; Thereby an end of the corresponding die cavity of said gradient slide block is the skewed product that makes and forms an angling hole in a corresponding end; The gradient of said angling hole is identical with the gradient of the upper surface of said slide block, thereby the horizontal product that makes of an end of the corresponding die cavity of said slide block forms straight hole in a corresponding end, and the gradient slide block breaks away from the angling hole with gradient during the demoulding along the slide block upper surface; Slide block breaks away from straight straight hole more then, just can easily accomplish shaping and demoulding.

The specific embodiment

Be the technology contents that specifies the utility model, structural feature, the effect that realized, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1, the utility model mould is used for the product 200 that moulding one side has angling hole 210 and straight hole 220, and it comprises mother module core 10, male model benevolence 20, slide block 30, gradient slide block 40, guide pillar 50 and thimble 60.The upper surface of said slide block 30 has a gradient, and said gradient slide block 40 closely places the upper surface of said slide block 30, forms die cavity (figure does not show) between said mother module core 10, male model benevolence 20, slide block 30, the gradient slide block 40.Said gradient slide block 40 has first pilot hole 41 that connects self, and slide block 30 has second pilot hole 31 that connects self, and the diameter of said first pilot hole 41 is less than the diameter of said second pilot hole 31.One end of said guide pillar 50 is fixed on the said mother module core 10; The other end is inserted in said first, second pilot hole; The axis of said first pilot hole 41 is positioned at the side of the axis of said second pilot hole 31 near product during matched moulds; Side away from die cavity of corresponding said second pilot hole 31 of the upper surface of said slide block 30 also is provided with locating part 32, when being used for the demoulding and extracting guide pillar 50, prevent gradient slide block 40 from the upper surface landing of slide block 30 so that damage gradient slide block 40.Thereby an end of said gradient slide block 40 corresponding die cavities is the skewed product 200 that makes forms an angling hole 210 in a corresponding end; The gradient of said angling hole 210 is identical with the gradient of the upper surface of said slide block 30; Thereby the horizontal product 200 that makes of an end of said slide block 30 corresponding die cavities forms straight hole 220 in a corresponding end; Said male model benevolence 20 has the centre hole 21 that is connected with said die cavity, and said thimble 60 slidably is inserted in the said centre hole 21.

The operation principle of the utility model mould 100 is following:

During matched moulds, male model benevolence 20, slide block 30 and gradient slide block 40 place on the pedestal 300, and gradient slide block 40 places the upper surface of said slide block 30, and on gradient slide block 40, then die cavity forms mother module core 10 matched moulds.One end of guide pillar 50 is fixed on the mother module core 10, and the other end is inserted in said first, second pilot hole, and extends in the cushion hole 310 of pedestal 300, and shovel machine 400 is pressed in mother module core 10, slide block 30 and gradient slide block 40 side away from die cavity.The interior injection moulding of past die cavity is formable products 200 just.

Consult Fig. 2 to Fig. 5; During the demoulding, mother module core 10 is upwards opened, and moves to the direction away from die cavity; At this moment; Drive gradient slide block 40 moves to the direction away from die cavity along the upper surface of slide block 30 thereby guide pillar 50 moves up, and gradient slide block 40 slowly breaks away from from the angling hole 210 of product 200, and then guide pillar 50 contacts with the side inwall of second pilot hole 31 away from die cavity; And then promotion gradient slide block 40 moves to the direction away from die cavity with slide block 30; Thereby slide block 30 is spun off from the straight hole 220 of product 200, and mother module core 10 and guide pillar 50 continues upwards to open to guide pillar 50 and breaks away from gradient slide blocks 40 afterwards, and then thimble 60 moves up and ejects product 200 and get final product.

As stated; The utility model mould has slide block 30 and gradient slide block 40; The upper surface of said slide block 30 has a gradient; Said gradient slide block 40 places on the said slide block 30 slidably, forms an angling hole 210 thereby an end of said gradient slide block 40 corresponding die cavities is the skewed product 200 that makes in a corresponding end, and the gradient of said angling hole 210 is identical with the gradient of the upper surface of said slide block 30; Thereby the horizontal product 200 that makes of an end of said slide block 30 corresponding die cavities forms straight hole 220 in a corresponding end; Gradient slide block 40 breaks away from the angling hole 210 with gradient along slide block 30 upper surfaces during the demoulding, and slide block 30 breaks away from straight straight hole 220 more then, just can easily accomplish shaping and demoulding.
