Abstract
The utility model discloses an injection mold for forming a two-color product. The injection mold comprises a moving mold and a fixing mold, wherein the fixing mold corresponds to a two-color injection device, and a first color portion mold cavity of the product is formed between the fixing mold and the moving mold. The injection mold is characterized in that a moving insert of the moving mold is arranged on a mold cavity portion of the moving mold, a sliding block is arranged between the fixing mold and the moving mold, a second color portion mold cavity of the plastic product is formed between opposite end faces of the moving insert of the moving mold and the sliding block, the moving insert of the moving mold and the sliding block move vertical to a mold-opening direction, and the stroke distance of the reciprocating movement of the moving insert of the moving mold and the sliding block is designed to the thickness of a second color portion of the plastic product. The injection mold has the advantages that the two-color injection molding is achieved through a mold in a mold opening process, and the two-color injection molding product cost is reduced.
Description
Technical field
The utility model involves the plastic products mould, particularly relates to the injection mold of the double-colored goods of a kind of moulding.
Technical background
Moulding dual-color plastic goods generally adopt the double coloured plastic injection machine injection moulding to finish, but the double coloured plastic injection machine cost is very high, also there is the mould of two dynamic model die devices of a kind of adapted to realize double-shot moulding, one of them dynamic model cooperates formed cavity dimension to cooperate formed cavity dimension with cover half greater than the another one dynamic model in described two dynamic models with cover half, the difference of its injection moulding process and common double-shot molding method is that the traveling priority of two dynamic models by moving platen on same mould comes successively and the cover half matched moulds, finishes the Double colour double-deck injection moulding.This mould need two dynamic models, so its cost is also higher.
The utility model content:
It is that technical problem is to overcome the deficiencies in the prior art that the utility model will solve, and a kind of simple in structure, a kind of injection mold for the double-colored goods of moulding that cost is low is provided.
A kind of injection mold for the double-colored goods of moulding of the utility model, comprise dynamic model and cover half, cover half is corresponding with the double color injection device, the the first color part die cavity that forms goods is arranged between dynamic model and the cover half, it is characterized in that: the cavity section of described dynamic model is equipped with the movable insert of dynamic model, between cover half and dynamic model, slide block is housed, form the second color part die cavity of plastic products between the movable insert of dynamic model and the slide block opposing end surface, the movable insert of dynamic model and slide block are perpendicular to the activity of die sinking direction, mould is to change like this die cavity: the control device of die drive unit is connected by RCA with the double color injection device, the movable insert of dynamic model and slide block are driven by drive unit respectively and do the synchronous reciprocating motion, because the movable insert of described dynamic model is connected with drive unit with slide block, and under the effect of drive unit, move back and forth perpendicular to the die sinking direction, first drive the movable insert of dynamic model and slide block in the direction perpendicular to die sinking by drive unit, move to the second assigned address by the first assigned address, movable insert and slide block by drive unit driving dynamic model returns to the first assigned address in the direction perpendicular to die sinking by the second assigned address again, and described the first assigned address is the position that the first color part die cavity and the second color part die cavity are isolated mutually; The second assigned address is the position that the first color part die cavity and the second color part die cavity are interconnected; The reciprocating stroke distances of the movable insert of described dynamic model and slide block is designed to the thickness of goods the second color part, and so, a mold just can be finished double-shot moulding.
The beneficial effects of the utility model are: can only use once cover (cover half and a dynamic model) mould, a die sinking and can realize double-shot moulding.Alleviated the cost of double-shot moulding product.
Description of drawings
Accompanying drawing 1 is in the die structure dwg of the first assigned address for dynamic model movable insert, slide block among the utility model embodiment.
Accompanying drawing 2 is in the die structure dwg of the second assigned address for dynamic model movable insert, slide block among the utility model embodiment.
The specific embodiment
A kind of injection mold for the double-colored goods of moulding, comprise dynamic model 1 and cover half 2, cover half 2 is corresponding with the double color injection device, the the first color part die cavity 3 that forms goods is arranged between dynamic model 1 and the cover half 2, it is characterized in that: the cavity section of described dynamic model 1 is equipped with the movable insert 4 of dynamic model 1, between cover half 2 and dynamic model 1, slide block 5 is housed, form the second color part die cavity 7 of plastic products between the movable insert 4 of dynamic model 1 and slide block 5 opposing end surfaces, the movable insert 4 of dynamic model and slide block 5 are perpendicular to the activity of die sinking direction, mould is to change like this die cavity: the control device of die drive unit is connected by RCA with the double color injection device, the movable insert 4 of dynamic model 1 is driven by drive unit respectively with slide block 5 and does the synchronous reciprocating motion, because the movable insert 4 of described dynamic model 1 is connected with drive unit with slide block 5, and under the effect of drive unit, move back and forth perpendicular to the die sinking direction, movable insert 4 by drive unit driving dynamic model 1 moves to second assigned address perpendicular to the die sinking direction by the first assigned address with slide block 5 first, movable insert 4 by drive unit driving dynamic model 1 returns to first assigned address perpendicular to the die sinking direction by the second assigned address with slide block 5 again, and described the first assigned address is the positions that the first color part die cavity 3 and the second color part die cavity 7 are isolated mutually; The second assigned address is the position that the first color part die cavity 3 and the second color part die cavity 7 are interconnected; Movable insert 4 and the slide block 5 reciprocating stroke distances of described dynamic model 1 are designed to the thickness of goods the second color part, and so, a mold just can be finished double-shot moulding.
