Abstract
The utility model provides a structure for protecting the metal insert appearance in a mould, and the structure is characterized in that the surface of a metal insert has small possibility of being strained, and a mould core has small possibility of being strained, therefore the production cost is low. The structure comprises a product cavity, a runner, a front mould core, a rear mould core and the metal insert, wherein the runner is communicated with the product cavity, and the metal insert is communicated with the product cavity. The structure is characterized in that an engineering plastic sleeve is arranged between the outer surface of the metal insert and the inner surfaces of the front mould core and the rear mould core; the outer surface of the metal insert is bound with a mounting slot on the inner surface of the engineering plastics sleeve; and the outer surface of the engineering plastics sleeve is bound with the inner surfaces of the front mould core and the rear mould core.
Description
Technical field
The utility model relates to the technical field of structures of mould, is specially the structure of protection metal insert outward appearance in a kind of 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 utility model provides the structure of protection metal insert outward appearance in a kind of mould, and 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 a kind of 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 the said structure of the utility model, 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 the front view structural representation of the utility model.
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.
