Abstract

The utility model provides a rotating quitting barb type insert core, comprising an insert core and a core insert, wherein the core insert is inlaid with the insert core, and the barb position of the insert core is provided with a square groove the bottom part of which is provided with a knock-out pin. The insert core is a rotating insert core, one end face is a shut off face, and three faces are inclined faces. The side face of a rotating insert core body is provided with a through hole, and a location pin penetrates through the through hole of side face of the rotating insert core body to fix the rotating insert core into the square groove of the insert core. A spring and the knock-out pin are arranged in a knock-out pin hole of the square groove. The utility model has the advantages of simple structure and short processing cycle. The traditional slide block and an angle pin quitting body are replaced by the rotating quitting barb type insert core, so the size of a die holder is reduced.

Description

Rotation is withdrawed from fluking type and is gone into son

Technical field

The utility model relates to into son, and specifically a kind of rotation is withdrawed from fluking type and gone into son.

Background technology

In the middle of the plastic mould manufacturing industry, when the plastic cement finished product has barb directly during die sinking, barb withdrawing mode commonly used such as often adopt slide block to withdraw from, taper pin withdraws from makes it finish the die sinking action smoothly and takes out the plastic cement finished product.

On plastic cement finished product madial wall, barb is arranged, and under the situation of die space deficiency, can advise that then the product design personnel revise finished product cancellation barb or the withdrawing mode of barb is designed to the inner slide withdrawing mode.Adopt the withdrawing mode of inner slide, the die holder of this mould can become greatly, and expense 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, provides a kind of rotation to withdraw from fluking type and goes into son.

The utility model provides a kind of rotation to withdraw from fluking type to go into son, includes son and male model benevolence.Male model benevolence, it studs with into son, and the barb place of going into son has square groove, and its square groove bottom is provided with and ejects pin-and-hole, and the length of this square groove is gone into sub length and is equated with rotatable; Go into son, it goes into son for rotatable, and an end face is a breaking face, and three is the identical inclined-plane of gradient, and this is rotatable goes into sub-body side and be provided with circular through hole; Alignment pin, it passes this rotatable circular through hole of going into sub-body side, and its two ends are arranged on into the dual-side in the sub-square groove, go into son and are fixed in the square groove on the son rotatable; Ejecting of square groove bottom is provided with spring and knock pin in the pin-and-hole, this knock pin one end is a hanging platform, and its hanging platform is connected with spring, and the other end passes and ejects pin-and-hole and prop up the rotatable inclined-plane of going into sub-bottom surface.

More excellent, described rotatable go into the end limit of sub-breaking face and the distance that there is 3mm to 5mm on the finished product limit.

More excellent, described male model benevolence middle part edge go into son, this width of going into son is with rotatable to go into sub width identical.

Compared with prior art, fluking type is withdrawed from the utility model rotation, and to go into minor structure simple, process-cycle is short, and the matched moulds difficulty is little, when on the plastic cement finished product madial wall barb being arranged, needn't revise product, realization product design personnel's that just can be complete initial design theory, withdraw from fluking type with rotation and go into son and substituted traditional slide block, taper pin drawing-out mechanism, reduced the size of die holder integral body.

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, for the structural representation that fluking type is gone into son is withdrawed from the utility model rotation.Rotatablely go into son 1 end face is arranged is breaking face 2 and three inclined-

planes

3,4,5 that gradient is identical.Wherein there is the distance 16 of 3mm to 5mm on the end limit of breaking face 2 and finished product 15 limits, and when matched moulds, the breaking face of this segment distance 16 and mother module core 6 lumping together tightly forms one section sealing face, can prevent that burr from appearring in finished product 15 when injection mo(u)lding.And this is rotatable goes into sub 1 body side and is provided with a circular through hole 7 near middle position, is used to be provided with alignment pin 8.In addition, stud with one in the middle of this male model benevolence 9 and go into son 10, the rotary son 1 of going into is installed for convenience, it is gone into son 10 width and goes into sub 1 width and equate with rotary, this barb place of going into son 10 has a square groove 11, square groove 11 bottoms are provided with and eject pin-and-hole 12, and square groove 11 is used to place the rotary son 1 of going into, and its length is gone into sub 1 length and equated with rotary.Make alignment pin 8 pass rotatable manhole 7 of going on sub 1 body, its two ends are arranged on the dual-side in the square groove 11, and this is rotatablely gone into son 1 and be fixed in the square groove 11 on the son 10.Ejecting of square groove 11 bottoms is provided with spring 13 and knock pin 14 in the pin-and-hole 12, an end of knock pin 14 is a hanging platform, and its hanging platform is connected with spring 13, and the other end passes and ejects pin-and-hole 12 and prop up the rotatable inclined-plane 3 of going into sub 1 bottom surface.

When the matched moulds state, the breaking face of mother module core 6 is pushed down rotatable breaking face 2 of going into son 1, under the effect of this downward force, rotatablely go into son 1 and be rotated counterclockwise around alignment pin 8, fit to move downward again the time up to mother module core 6 and male model benevolence 9, rotatable barb of going on the son 1 resets, and stops the rotation, at this moment injection mo(u)lding finished product 15 smoothly just.Because the rotatable inclined-plane 3 of going into sub 1 bottom surface is connected with knock pin 14, rotatablely to go into son 1 and be rotated counterclockwise and knock pin 14 will be depressed, knock pin 14 moves downward the spring 13 that makes below being fixed on and is compressed the generation strain.

Please continue to consult Fig. 2, for the die sinking schematic diagram that fluking type is gone into son is withdrawed from the utility model rotation.When die opening state, mother module core 6 moves upward, acting on rotatable power of going on the sub 1 breaking face 2 disappears, spring 13 below the knock pin 14 recovers strain, the elastic force promotion knock pin 14 that spring 13 recovers the strain generation moves upward, by the rotatable inclined-plane 3 of going into sub 1 bottom surface of knock pin 14 contacts, rotatablely go into son 1 and turn clockwise around alignment pin 8 and withdraw from the barb of finished product 15, finished product 15 can be ejected 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.
