Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to figs. 1 to Fig. 5：Two core socket injection molds, including mould bases 1, preceding mould 2, rear mold 3 and liftout attachment 4, preceding mould 2
It is set on mould bases 1 with rear mold 3, preceding mould 2 and rear mold 3 are equipped with runner 5, and preceding mould 2 is equipped with the first cavity, and rear mold 3 is equipped with second
Cavity, the first cavity and the second cavity are corresponding, and are connected with runner, and liftout attachment 4 includes the first thimble 41 and the second top
Needle 42, the first thimble 41 can be abutted against with one end of two core sockets, and the second thimble 42 is equipped with boss 6,6 and two core socket of boss
The other end it is corresponding.
In injection, preceding mould 2 is fitted close the two cores socket mold with rear mold 3, and the first cavity and the second cavity closely paste
It closes, sizing material enters the first cavity through runner and Second-Type intracavitary is molded, and liftout attachment 4 pushes up product after the completion of molding
Go out.
Second thimble 42 includes the first service portion 421 and the second service portion 422, the first service portion 421 and the second service portion
422 are respectively coated by the outside of two core sockets, and boss 6 is located on the second service portion 422.
When the second thimble 42 acts on two core sockets, the end face of boss 6 and the other end of two core sockets abut against.Two cores
At the time of molding, the 6 and two core socket other end of boss has certain distance to socket；When product needs to release, external force pushes second
Thimble 42 moves so that boss 6 is moved to the other end of two core sockets, can be by the end face of two core sockets and type by boss 6
Chamber detaches, and reduces the knockout press of the first thimble 41.
For the two core socket injection molds of the utility model after the completion of injection molding, external force pushes the second thimble 42 to move,
The end face of product is first detached with cavity；Product is axially ejected by the first thimble 41 again, realizes entire product
Demoulding.So as to which the injection mold, without increasing the complexity of mold, passes through when being molded two core socket irregular products
Two thimbles can realize the demoulding of product, and ensure that product end surface is indeformable, have preferable stripping result.
The distance of first service portion, 421 bottom and 422 bottom of the second service portion is more than the outer diameter of two core socket one end.By
This, it is possible to reduce the contact area of the second thimble 42 and product reduces knockout press required during demoulding, improves working efficiency.
First cavity and the second cavity are four, and are distributed on respectively on preceding mould 2 and rear mold 3.It as a result, once can be into
Four products of type improve the production efficiency of product.
Installation of the preceding mould 2 on mould bases 1 for convenience, two core socket injection molds further include front template 7,7 sets of front template
2 outside of mould before being located at, external force can be acted on front template 7 as a result, then is acted on preceding mould 2 by front template 7, before convenient
The connection of mould 2 and other component.
In order to facilitate installation of the rear mold 3 on mould bases 1, two core socket injection molds further include rear pattern plate 8,8 sets of rear pattern plate
3 outside of rear mold is located at, external force can be acted on rear pattern plate 8 as a result, then is acted in rear mold 3 by rear pattern plate 8, after convenient
The connection of mould 3 and other component.
Preceding mould 2 is equipped with positive stop lug boss 21, and rear mold 3 is equipped with and 21 matched groove 31 of positive stop lug boss.It is thus, it is possible to convenient
Preceding mould 2 and the installation of rear mold 3 are conducive to the two and are fitted close, improve product quality, improve mold installation effectiveness.
Above is only the preferred embodiment of the utility model, it is noted that for those of ordinary skill in the art
For, under the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this
