Specific embodiment
Referring to shown in Fig. 1-6, a kind of sliding block band internal loose core injection mold, including sequentially connected slide block assembly, limit group
Part and driving assembly；The slide block assembly includes slide block insert 1, the first connecting plate 2 and the second connecting plate 3, slide block insert tail end
Be sequentially connected by the downside of 4, left sliding shoe 5 on the upside of tail, tail 6 and right sliding shoe 7 surround cylindricality and sequentially pass through the first connecting plate and
Second connecting plate；The slide block insert is connect through end end with dovetails 8；The left and right sliding shoe medial surface is equipped with
The dovetail groove 10 being used cooperatively with the dovetail flanges 9 in dovetails, left and right sliding shoe are all provided on the lateral surface of product one end
There is screw thread 11 corresponding with product.It is used by dovetails, to make 22 female thread portion of product both direction in demoulding
Simultaneously to slide block insert center movement core pulling；Limiting device connection sliding block component and driving assembly limit the movement of slide block assembly
Stroke, driving assembly drive slide block assembly mobile.
It is slide block demolding mechanism introduction below:
First time core pulling: under the action of two spring forces, slide block insert, the first connecting plate, the second connecting plate (uses spiral shell
Silk is fixed as an entirety) first remain stationary.Oil cylinder drives take-up housing to move backward, and dovetails are fixed on take-up housing, work as cunning
When block moves backward, the tapered dovetail flange of dovetails can force the block that horizontally slips to be transported to center in extraction process
Dynamic (to center movement both left slider, sliding block direction is mobile to the right, and right sliding block is mobile to left slider direction), makes to horizontally slip on block
Screw thread and product be detached from.After opening certain distance between the second connecting plate and take-up housing, the limit on the second connecting plate is locked
Position screw can hold take-up housing, so that cannot open again between the second connecting plate and take-up housing.
Second of core pulling: oil cylinder continuation moves backward, and forcing entire sliding block includes take-up housing, and the first connecting plate, second connects
Fishplate bar, the continuation such as slide block insert move backward, complete after slide block insert is entirely fully drawn out product, and for sliding block opening action
At.
The driving component includes drive cylinder 12, the take-up housing 13 of drive cylinder movable end connection.Pass through drive cylinder
Drive take-up housing mobile.
The drive cylinder can use oil cylinder, cylinder.It is bigger using oil cylinder power.
The limit assembly includes the spring 15 being arranged on the limited screw 14 and limited screw being oppositely arranged；The limit
Screw one end connects the second connecting plate, and the other end is telescopic to be mounted on take-up housing；The peace that two limited screw is surrounded
Dress is placed with dovetails in space.By the way that limited screw is arranged, and the limited screw other end is telescopic is mounted on take-up housing,
In this way when drive cylinder driving take-up housing is mobile, take-up housing will first be located at the limited screw in take-up housing and remove, when being moved to
When the extreme position of limited screw, the mobile drive limited screw of take-up housing is mobile, drives the second connecting plate mobile indirectly, thus
Slide block assembly is taken out of outside product；Guarantee that the second connecting plate and take-up housing are opened by setting spring and completes first time core pulling.
Two guide rods 16 are additionally provided between second connecting plate and take-up housing, the guide rod one end and the second connecting plate
Connection, the other end is telescopic to be arranged on take-up housing.When by setting guide rod convenient for slide block assembly and mobile take-up housing
Guiding.
Sliding shoe sliding slot 17 is equipped on the upside of the tail and on the downside of tail；It is equipped with and slides on the left and right sliding shoe
The boss 19 that block sliding slot is used cooperatively.Sliding block block sliding block two sides on the upside of tail and on the downside of tail are that (through slot is sliding to through slot
The plane of block sliding slot two sides), left and right sliding shoe boss two sides all have flange 20 corresponding with through slot 18, and (through slot is convex
The plane of platform two sides), by the cooperation of sliding shoe sliding slot and boss 19, through slot and flange with the use of in order to will it is upper and lower,
Left and right sliding shoe fits together, and the block that horizontally slips can be in through slot slide inside.
The take-up housing is relatively set with two pressing plates 21 on the side of dovetails, which is with take-up housing side
Beginning position extends on the first connecting plate side.Take-up housing, the first connecting plate are pushed down by the way that pressing plate is arranged, the second connecting plate, and
And inside is equipped with guide rail in order to play guiding role when take-up housing is mobile.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, it is all according to
According to any simple modification to the above embodiments in technical spirit of the invention, equivalent variations, guarantor of the invention is each fallen within
Within the scope of shield.
