A kind of IMD inserts and wears mould
Technical field
The utility model relates to the slotting mould of wearing of a kind of IMD.
Background technology
IMD is a kind of surface decoration technique, generally comprises surface sclerosis transparent membrane, middle printing pattern layer and back side injection molded layers, in the middle of ink is placed on, can make product rub resistance, prevents that surface from being scratched, and can keep for a long time the distinctness of color to be difficult for fading.In actual production, diaphragm is generally by hot-forming, and therefore diaphragm can cause moulding diaphragm can not mate completely with injection moulding die cavity because shrinking after hot-forming, and diaphragm can be pressed onto diaphragm because fixing shakiness easily exceeds when die joint causes matched moulds and cause product rejection.The utility model provides a kind of mould that reaches fixing diaphragm by increasing the degree of depth of die cavity for this reason.
Utility model content
In order to address the above problem, the utility model provides a kind of IMD to insert and wears mould.
The utility model solves the technical scheme that its technical problem adopts:
A kind of IMD inserts and wears mould, comprising:
Patrix, is provided with sprue gate, first passage and some die cavitys, and sprue gate is communicated with first passage entrance, and first passage exports between some die cavitys;
Counterdie, is provided with some core rods that mate with die cavity, is also provided with some second channels on counterdie, and second channel entrance is communicated with first passage outlet after matched moulds, and second channel outlet is positioned on core rod.
Described die cavity comprises cavity forming portion and die cavity location division, and described core rod comprises core rod forming part and core rod location division, and described die cavity location division and core rod location division match.
Described die cavity location division is provided with a columniform cavity, and described core rod location division is set to a cylindrical column.
Described second channel inner chamber is ox horn type, and large one end is second channel entrance, and little one end is second channel outlet.
The utility model also comprises some supplemental core, and supplemental core one end is plugged on core rod, and the other end is positioned at die cavity.
Described die cavity and core rod are respectively arranged with two.
The beneficial effects of the utility model are: the utility model leads to die cavity location division is set in die cavity, extended the degree of depth of die cavity, to reach the effect of fixing diaphragm, core rod location division is set on core rod in order to coordinate die cavity location division, plays the effect of location core rod and further fixing diaphragm simultaneously.The utility model is simple in structure, practical, and effect is splendid.

Detailed description of the invention
With reference to Fig. 1~Fig. 3, the utility model be a kind of IMD insert wear mould, comprising:
Patrix 1, is provided with sprue gate 3, first passage and two die cavitys, and sprue gate 3 is communicated with first passage entrance, and first passage exports between two die cavitys;
Counterdie 2, is provided with two core rods that mate with die cavity, is also provided with two second channels 23 on counterdie 2, and second channel 23 entrances are communicated with first passage outlet after matched moulds, and second channel 23 outlets are positioned on core rod;
Die cavity comprises cavity forming portion 11 and die cavity location division 12, core rod comprises core rod forming part 21 and core rod location division 22, die cavity location division 12 matches with core rod location division 22, and die cavity location division 12 is provided with a columniform cavity, and core rod location division 22 is set to a cylindrical column.The utility model leads to die cavity location division 12 is set in die cavity, extended the degree of depth of die cavity, to reach the effect of fixing diaphragm, core rod location division 22 is set on core rod in order to coordinate die cavity location division 12 simultaneously, play the effect of location core rod and further fixing diaphragm.The utility model is simple in structure, practical, and effect is splendid.
As shown in the figure, second channel 23 inner chambers are ox horn type, and large one end is second channel 23 entrances, and little one end is that second channel 23 exports.Adopt ox horn to enter rubber moulding formula and can improve the yields of the utility model in the time producing.
The utility model also comprises some supplemental core 4, is used to form the suspension column on product 5, and supplemental core 4 one end are plugged on core rod, and the other end is positioned at die cavity.
Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replace is all included in the scope that the application's claim sets.
