Description
Technical field
The utility model relates to the injection mold technical field, particularly a kind ofly can realize the bicolor injection mould of depoling rotational forming on common double coloured plastic injection machine.
Background technology
Double-color mold claims again many material injection molds, and injection machine used is furnished with two or more barrel, can be simultaneously or sequential injection different plastics more than two kinds or two kinds, be called for short double coloured plastic injection machine.Common double-shot moulding is to do two different die cavities on cover half, only needs cover half to change the chamber during injection mo(u)lding, uses common double coloured plastic injection machine just can complete, and common double-shot moulding has dynamic model rotation and two kinds of patterns of dynamic model translation at present.But common double-shot moulding is the injection mo(u)lding of applicable conventional double-colored product only, and when running into the product two sides and all need to carry out double-shot moulding, common double-shot moulding just can't meet the demands.For the common employing of such product is depoling rotation injection mo(u)lding, depoling rotation double-shot moulding is to adopt special-purpose double coloured plastic injection machine and depoling rotary die, moving, the cover half of depoling rotary die all needs to change the chamber in injection moulding process, its Shooting Technique flow process is: injection for the first time, then die sinking, moving platen is ejected Rotate 180 ° by piston rod again, then matched moulds, for the second time injection.Whole process injection-moulding device dynamic model template is not rotated, and just mould dynamic model integral body is ejected again and rotates.Because common double-shot moulding equipment can only be realized whole moving die system rotation, can't mate conventional depoling rotary die.Therefore to carry out depoling rotation injection mo(u)lding and can only adopt special-purpose injection-moulding device, certainly will cause like this idle of original common injection-moulding device, and need to buy special depoling rotational forming injection-moulding device, thereby increase production cost.
The utility model content
The utility model has solved the problem that can't complete depoling rotation injection mo(u)lding on common double-colored injection-moulding device, provides a kind of and can carry out the bicolor injection mould of depoling rotational forming on common double coloured plastic injection machine.
for solving the problems of the technologies described above, the utility model has adopted a kind of bicolor injection mould, comprise cover half, dynamic model, oil cylinder, piston rod, guide pillar and dynamic model flange, described dynamic model comprises moving platen A, moving platen B, moving platen C and dynamic model mould bases, described moving platen C is arranged on the dynamic model mould bases, described guide pillar is arranged on the dynamic model mould bases, moving platen A connects by guide pillar with moving platen C, moving platen B is arranged between moving platen A and moving platen C, described dynamic model flange is fixedly mounted on moving platen B, described oil cylinder is arranged on the dynamic model mould bases, in-oil cylinder piston rod connects moving platen A, be installed with fixed leg on described cover half, the other end of described fixed leg is connected with dynamic model flange on moving platen B.
The beneficial effect that the utlity model has: conventional depoling rotation injection mo(u)lding is to allow mavable module core eject rotation, and the dynamic model mould bases does not rotate, if allowing mavable module core eject does not rotate, and allows the rotation of dynamic model mould bases equally also can reach identical effect.Based on this design, this mould is by arranging fixed leg between the fixed half and moving half plate B of mould, cover half is fixedly connected with moving platen B, realization is the rotation of dynamic model mould bases in injection moulding process, but moving platen B is owing to being fixedly connected with cover half, do not rotate, reach the effect identical with depoling rotation injection mo(u)lding.Use this mould realizing depoling rotation injection mo(u)lding on common double coloured plastic injection machine, and do not need to buy in addition special-purpose double color injection machine, thereby reduced production cost.
Description of drawings
Fig. 1 is this utility model structural representation.
In figure: 1, moving platen A; 2, moving platen B; 3, moving platen C; 4, dynamic model mould bases; 5, dynamic model; 6, oil cylinder; 7, piston rod; 8, dynamic model flange; 9, guide pillar; 10, fixed leg.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
as shown be a kind of bicolor injection mould, comprise cover half 5, dynamic model, oil cylinder 6, piston rod 7, guide pillar 9 and dynamic model flange 8, dynamic model comprises moving platen A1, moving platen B2, moving platen C3 and dynamic model mould bases 4, moving platen C3 is arranged on dynamic model mould bases 4, guide pillar 9 is arranged on dynamic model mould bases 4, moving platen A1 is connected guide pillar 9 with moving platen C3 and connects, moving platen B2 is arranged between moving platen A1 and moving platen C3, dynamic model flange 8 is fixedly mounted on moving platen B2, oil cylinder 6 is arranged on dynamic model mould bases 4, piston rod 7 in oil cylinder 6 connects moving platen A1, be installed with fixed leg 10 on cover half 5, the other end of fixed leg 10 is connected with dynamic model flange 8 on moving platen B2.
Because common double coloured plastic injection machine can only be realized whole moving die system rotation, when using conventional mold injection, can only complete dynamic model and change the chamber, in order to allow this mould complete the depoling rotational forming on common double coloured plastic injection machine, realize that active and inactive mold changes the purpose in chamber.To allow mavable module core eject rotation according to the depoling rotation; and the dynamic model mould bases does not rotate to realize that active and inactive mold changes the principle in chamber; we adopt and to allow mavable module core eject not rotate; the design of dynamic model mould bases rotation has realized that completing active and inactive mold on common double coloured plastic injection machine changes the chamber, has reached the effect of depoling rotational forming.On this mould; by allowing moving platen B2 not rotate; 4 rotations of dynamic model mould bases realize that the active and inactive mold of mould changes the chamber; in order to allow moving platen B2 not rotate, due in injection moulding process, cover half 5 is non-rotary; so by fixed installation fixed leg 10 on cover half 5; connect moving platen B2 by fixed leg 10, thereby moving platen B2 is fixed, realized completing the purpose of depoling rotation injection mo(u)lding on common double coloured plastic injection machine.
use this mould to carry out the technical process of injection moulding as follows: injection at first for the first time, complete the rear active and inactive mold die sinking of injection, dynamic model is certain to the direction opposite with cover half 5, extract out in the driven modulus method orchid 8 of fixed leg 10 this moment, and and dynamic model flange 8 between be fixed, relatively rotating between restriction dynamic model flange 8 and fixed leg 10, oil cylinder 6 on dynamic model mould bases 4 ejects moving platen A1 by piston rod 7 along guide pillar 9, then whole dynamic model mould bases 4, moving platen A1, moving platen C3 is rotated under the effect of injection machine and changes the chamber, in this process owing to adopting fixed bar 10 to be connected between moving platen B2 and cover half 5, it is motionless that moving platen B2 keeps under the effect of fixed leg 10, thereby complete active and inactive mold and change the chamber, after dynamic model mould bases 4, moving platen A1, moving platen C3 were rotated in place, oil cylinder 6 pulled moving platen A1 to reset by piston rod 7, and whole active and inactive mold matched moulds is completed injection for the second time at last.
The project organization of this mould has very high requirement for the machining accuracy of mould, must guarantee the postrotational positioning accuracy of dynamic model, realize to fit by die cavity complete and moving platen B2 and cover half 5 after oil cylinder 6 retracts moving platen A1, and necessary consistent, the coincidence of the benchmark of each template is to guarantee the Forming Quality of final products.
