Abstract

The utility model provides a novel built-in demoulding mechanism, wherein an insert end surface is a slope leaning surface, inclined chamfers are arranged between two sides and the bottom end, and an insert is arranged at a male mould core of the mould. A cushion block is arranged below the insert, a thimble is clamped in the cushion block, a hanging table is arranged at one end of the thimble, an elastic member is arranged below the hanging table, and the other end penetrates through the cushion block and props against the inclined chamfers at the bottom ends of the insert. The novel built-in demoulding mechanism has simple structure, the inverse hooking and retreating mechanism of the mould is simplified, and the design conception of designers for products can be completely implemented.

Description

System mould emptier in novel

Technical field

The utility model relates to the mould emptier of plastic mould, specifically a kind of novel interior system mould emptier.

Background technology

In the plastic mould manufacturing industry, the barb of plastic cement products generally adopts the mode of slide block and taper pin to withdraw from, mould is opened after, can take out the plastic cement finished product in the die cavity smoothly.

When barb is in the madial wall of product, and the die space deficiency, in the time of can't arranging taper pin mechanism, tends to suggestion product design personnel and revise finished product cancellation barb or the withdrawing mode of barb is designed to the inner slide withdrawing mode.Adopt inner slide to withdraw from the product barb, can make the die holder of mould become big, its expense also can increase accordingly, and inner slide mechanism is made up of a plurality of parts, its processed complex, and the process-cycle is long, and the matched moulds difficulty is big.

The utility model content

Because above-mentioned problem, the purpose of this utility model is to overcome the deficiencies in the prior art and defective, and a kind of novel interior system mould emptier is provided.

The utility model provide a kind of novel in the system mould emptier, going into sub-end face is breaking face, both sides and bottom are provided with chamfer, this goes into the male model benevolence that son is located at mould, and can be in this male model benevolence rotary moveable.Cushion block is located at the below into son, and thimble is sticked in the cushion block, and an end of this thimble is a hanging platform, and its hanging platform below is provided with an elastic component, and the other end passes cushion block and props up chamfer into sub-bottom.

More excellent, described chamfer of going into sub-both sides and bottom, its gradient equates.

More excellent, the elastic component that described thimble hanging platform below is provided with is a spring.

Compared with prior art, the utility model is simple in structure, has simplified the barb drawing-out mechanism of mould, makes product design personnel's design concept be able to complete enforcement.

The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

See also Fig. 1, be the structural representation of the novel interior system mould emptier of the utility model.But mould comprises the mother module core 106 and male model benevolence 109 of folding.Going into sub 101 end faces is breaking face 102, and both sides are provided with the identical chamfer of gradient 103,104,105 with the bottom, and this goes into the male model benevolence 106 that son 101 is located at mould, and can be in this male model benevolence 106 rotary moveable.Cushion block 107 is located at the below into son 101, thimble 108 is fastened in this cushion block 107, one end of this thimble 108 is a hanging platform, its hanging platform below is provided with an elastic component 110, this elastic component 110 is a spring, but be not limited only to this, present embodiment is that example is illustrated with the spring, and the other end of thimble 108 passes cushion block 107 and props up chamfer 105 into sub 101 bottoms.During matched moulds, go into son 101 breaking face 102 and fit, forms one section sealing face, and make, go into son 101 when resetting, the thimble 108 and the elastic component 110 of its below are depressed, make elastic component 110 generation elastic deformations into sub 101 spinning reductions with mother module core 106.

Please continue to consult Fig. 2, be the die sinking action schematic diagram of the novel interior system mould emptier of the utility model.After the product injection mo(u)lding, mother module core 106 separates with male model benevolence 109, the pressure that mother module core 106 acts on the sub 101 breaking faces 102 disappears, the elastic component 110 of thimble 108 belows recovers strain, the elastic force promotion thimble 108 that elastic component 110 recovers the elastic deformation generation moves upward, by the chamfer 105 that thimble 108 contacts are gone into sub 101 bottoms, go into the barb that product is withdrawed from son 101 rotations, make product can break away from mold cavity smoothly.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.

Claims

1. a novel interior system mould emptier is characterized in that, comprising:

Go into son, its end face is a breaking face, and both sides and bottom are provided with chamfer, and this goes into the male model benevolence that son is located at mould, and can be in this male model benevolence rotary moveable;

Cushion block, it is located at the above-mentioned below of going into son, and thimble is sticked in the cushion block, and an end of this thimble is a hanging platform, and its hanging platform below is provided with an elastic component, and the other end passes cushion block and props up chamfer into sub-bottom.

2. according to claim 1 novel in the system mould emptier, it is characterized in that: described chamfer of going into sub-both sides and bottom, its gradient is equal.

3. novel interior system mould emptier according to claim 1, it is characterized in that: the elastic component that described thimble hanging platform below is provided with is a spring.
