Description
Technical field
The utility model relates to the unsteady strong release mechanism of a kind of large specification sealed card ring mould, belongs to injection mold field, mainly for the production of plastic pipe sealing collar etc.
Background technology
In pipeline is laid, prior art generally adopts collar to be connected and fixed between will each plastic pipe mutual, so the sealing to collar and intensity have very high requirement.Therefore, this developer has designed a kind of enlarging shape collar, upper oral part at enlarging shape collar arranges back-off, infraoral at enlarging shape collar is provided with clasp, between clasp and back-off, form a sealing caulking groove, in sealing caulking groove, sealing ring is installed, is had good sealing, the intensity of enlarging shape collar is also fine.Producing sealing collar is generally to adopt the moulding of injection mold integral molded plastic, owing to being provided with sealing caulking groove in sealing collar, sealing has the caulking groove existence of inserting in caulking groove, so sealing collar cannot directly be ejected the demoulding after injection mo(u)lding, need first caulking groove to be inserted and deviate from from sealing caulking groove, sealing collar just can be ejected outside mould.General straight top and the lifter combination Double-ejection mode of adopting of the prior art sealing caulking groove demoulding, its shortcoming is mould inside complex structure, and Double-ejection action is unstable, and mould easily breaks down, and affects production efficiency.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, provides a kind of and adopts unsteady ejecting with pressure to eject and combine, simple in structure, having stable behavior, and the demoulding is smooth, the unsteady strong release mechanism of large specification sealed card ring mould that production efficiency is high.
The technical scheme of the unsteady strong release mechanism of the large specification sealed card of the utility model ring mould is: comprise stationary mould for mould plate and moving platen, cover half die cavity is set in solid plate, dynamic mould core is set in moving platen, gap between dynamic mould core and cover half die cavity forms die cavity, in die cavity, there is the sealing collar of moulding, the upper oral part of sealing collar is provided with back-off, the infraoral of sealing collar is provided with clasp, described moving platen is arranged on two mould pin, two mould underfooting are equipped with base plate, between two mould pin, upper plate and lower roof plate are set, push rod is installed on upper plate, it is characterized in that described dynamic mould core comprises back-off panelling, clasp panelling and core base plate form, back-off panelling matches with back-off, clasp panelling matches with clasp, described push rod is through moving platen, core base plate is connected back-off panelling with clasp panelling, mounting spring between core base plate and moving platen, in core base plate, be shaped with stopper slot, stop screw is set in stopper slot, stop screw connects moving platen through spring.
The large specification sealed card ring mould of the present utility model strong release mechanism that floats, when the demoulding, first mould die sinking, by injection machine power driven mold dynamic model part and the die sinking of cover half part, moving platen separates with solid plate, spring is under the locked mode pressure that there is no solid plate, by core base plate together with clasp panelling, back-off panelling and upwards floating-jacking of sealing collar, the outer wall that seals collar is deviate from from moving platen, die sinking finishes, again by injection machine powered lower roof plate and upper plate, upper plate drives push rod to promote upwards jack-up of back-off panelling, back-off panelling drives sealing collar, the clasp of sealing collar infraoral is forced to pull out from clasp panelling, clasp demoulding success, in clasp pull-out process, the ductility of having utilized plastic material itself to have, clasp can restore automatically, can not impact the quality of sealing collar.And back-off panelling itself is positioned at the inner side of back-off, in the time of the demoulding, can not block back-off, therefore, now only need again other die ejector pin will seal outside collar ejection die, or by artificial taking-up sealing collar, the demoulding complete.What the sealing collar demoulding of this programme adopted is also Double-ejection mode, but is ejected and pressure ejects and constitutes by spring floating, and structure is very simple, simplifies mould inside structure, saves cost, having stable behavior, reliable, and the demoulding is smooth, and production efficiency is high.
The large specification sealed card ring mould of the present utility model strong release mechanism that floats, between described push rod and moving platen, core base plate and clasp panelling, be equipped with guide pin bushing, there is guide pin bushing, both play the guiding role, avoided again rubbing between push rod and moving platen, core base plate and clasp panelling.Described push rod is connected through screw with back-off panelling, easy to connect, firm.
Brief description of the drawings
Fig. 1 is the unsteady strong release mechanism structural representation of large specification sealed card ring mould of the present utility model.
Detailed description of the invention
The utility model relates to the unsteady strong release mechanism of a kind of large specification sealed card ring mould, as shown in Figure 1, comprise stationary mould for mould plate 1 and moving platen 2, cover half die cavity is set in solid plate 1, in moving platen 2, dynamic mould core is set, gap between dynamic mould core and cover half die cavity forms die cavity, in die cavity, there is the sealing collar 4 of moulding, the upper oral part of sealing collar is provided with back-off 41, the infraoral of sealing collar is provided with clasp 42, described moving platen 2 is arranged on two mould pin 5, two mould pin 5 times are equipped with base plate 6, upper plate 7 and lower roof plate 8 are set between two mould pin 5, push rod 9 is installed on upper plate 7, described dynamic mould core comprises back-off panelling 10, clasp panelling 11 and core base plate 12 form, back-off panelling 10 matches with back-off 41, clasp panelling 11 matches with clasp 42, described push rod 9 is through moving platen 2, core base plate 12 is connected back-off panelling 10 with clasp panelling 11, mounting spring 13 between core base plate 12 and moving platen 2, in core base plate 12, be shaped with stopper slot 14, stop screw 15 is set in stopper slot, stop screw 14 connects moving platen 2 through spring 13.When the demoulding, first mould die sinking, by injection machine power driven mold dynamic model part and the die sinking of cover half part, moving platen 2 separates with solid plate 1, spring 13 is under the locked mode pressure that there is no solid plate 1, by core base plate 12 together with clasp panelling 11, back-off panelling 10 and upwards floating-jacking of sealing collar 4, the outer wall that seals collar 4 is deviate from from moving platen 2, die sinking finishes, again by injection machine powered lower roof plate 8 and upper plate 7, upper plate 7 drives push rod 9 to promote upwards jack-up of back-off panelling 10, back-off panelling 10 drives sealing collar 4, the clasp 42 of sealing collar 4 infraorals is forced from 11 pull-outs of clasp panelling, clasp 42 demoulding successes, in clasp pull-out process, the ductility of having utilized plastic material itself to have, clasp can restore automatically, can not impact the quality of sealing collar.And back-off panelling 10 itself is positioned at the inner side of back-off 41, in the time of the demoulding, can not block back-off, therefore, now only need again other die ejector pin will seal outside collar 4 ejection dies, or by artificial taking-up sealing collar, the demoulding complete.What the sealing collar demoulding of this programme adopted is also Double-ejection mode, but is ejected and pressure ejects and constitutes by spring floating, and structure is very simple, simplifies mould inside structure, saves cost, having stable behavior, reliable, and the demoulding is smooth, and production efficiency is high.Between described push rod 9 and moving platen 2, core base plate 12 and clasp panelling 11, be equipped with guide pin bushing 16, had guide pin bushing, both play the guiding role, avoid again friction between push rod and moving platen 2, core base plate 12 and clasp panelling 11.Described push rod 9 is connected through screw 17 with back-off panelling 10, easy to connect, firm.
