Abstract
The invention provides a rotary retreating barb type insert, which comprises an inert and a male die core. The inert is embedded into the male die core, a square groove is formed at a barb of the insert, and the bottom of the square groove is provided with an ejection pin; the insert is a rotary insert, one end face of the insert is a broken face, three faces of the insert are inclined planes, and the lateral surface of the rotary insert body is provided with a through hole; a positioning pin passes through the through hole on the lateral surface of the rotary insert body to fix the rotary insert in the square groove on the insert; and a spring and an ejection pin are arranged in ejection pin holes at the bottom of the square groove. The rotary retreating barb type insert has a simple structure and short processing period, and replaces a traditional sliding block or oblique pin retreating mechanism to reduce the size of a die holder.
Description
Technical field
The present invention relates to into son, specifically a kind of rotation is withdrawed from fluking type and is 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.
Summary of the invention
Because above-mentioned problem the objective of the invention is to overcome the deficiencies in the prior art and defective, provide a kind of rotation to withdraw from fluking type and go into son.
The invention provides a kind of rotation and withdraw from fluking type and go into son, include 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 present invention 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.
Description of drawings
Fig. 1 is for the structural representation that fluking type is gone into son is withdrawed from the present invention's rotation.
Fig. 2 is for the die sinking schematic diagram that fluking type is gone into son is withdrawed from the present invention's rotation.
The specific embodiment
For describing technology contents of the present invention, 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 present invention's 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 present invention's 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 invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by the scope of claims of the present invention.
