Abstract
The invention provides a structure of protecting appearances of metal inserts in a mould, which is characterized in that the surfaces of the metal inserts are not easy to pull, mould cores are not easy to pull, and further, the production cost is low. The structure of protecting the appearances of the metal inserts in the mould comprises product mould cavities, a runner, a front mould core, a rear mould core and the metal inserts, wherein the runner is communicated with the product mould cavities, and the metal inserts are communicated with the product mould cavities. The structure of protecting the appearances of the metal inserts in the mould is characterized in that engineering plastic sleeves are respectively arranged between the outer surfaces of the metal inserts and the inner surfaces of the front mould core and the rear mould core; the outer surfaces of the metal inserts are fitted with mounting slots on the inner surfaces of the engineering plastic sleeves; and the outer surfaces of the engineering plastic sleeves are fitted with the inner surfaces of the front mould core and the rear mould core.
Description
Technical field
The present invention relates to the technical field of structures of mould, be specially the structure of protection metal insert outward appearance in the mould.
Background technology
In the existing injection mold, often run into elder generation after mould inside is placed metal insert, the situation of injection moulding because metal insert directly contacts with die, is prone to cause the situation that pull on the metal insert surface, die is pulled then, causes production cost big.
Summary of the invention
To the problems referred to above, the invention provides the structure of protection metal insert outward appearance in the mould, it makes, and the metal insert surface is difficult for pulling, die is difficult for pulling, and then production cost is low.
The structure of protection metal insert outward appearance in the mould; Its technical scheme is such: it comprises product die cavity, runner, preceding die, back die, metal insert; Said runner is communicated with said product die cavity; Said metal insert is communicated with said product die cavity; It is characterized in that: said metal insert outer surface and said before the engineering plastics sleeve is housed between the inner surface of die, back die, the fit mounting groove of inner surface of said engineering plastics sleeve of the outer surface of said metal insert, the outer surface of said engineering plastics sleeve fit said before the inner surface of die, back die.
After adopting said structure of the present invention, because the outer surface of metal insert contacts with the inner surface of said engineering plastics sleeve, and the material surface pliability of engineering plastics sleeve is good, makes the outer surface of metal insert in injection molding process, be difficult for pulling; In addition, the inner surface of said preceding die, back die makes that die is difficult for pulling because the outer surface of engineering plastics sleeve is fitted; Even the engineering plastics sleeve weares and teares, the cost of its replacing is also very low; To sum up, it makes production cost low.
Description of drawings
Fig. 1 is a front view structural representation of the present invention.
The specific embodiment
See Fig. 1; It comprises product die cavity 1, runner 2, preceding die 3, back die 4, metal insert 5; Runner 2 is communicated with the product die cavity, and metal insert 5 is communicated with product die cavity 1, between the inner surface of metal insert 5 outer surfaces and preceding die 3, back die 4 the engineering plastics sleeve is housed; The mounting groove 7 of the inner surface of the outer surface applying engineering plastics sleeve of metal insert 5, the inner surface of die 3, back die 4 before the outer surface of engineering plastics sleeve is fitted.The engineering plastics sleeve is put together by upper bush 6, lower sleeve 8 two parts, and the mounting groove 7 of inner surface is put together by upper bush 6, lower sleeve 8 two parts.
