Description
Technical field
It the utility model is related to technical field of mold, and in particular to a kind of mould for applying special-shaped thimble.
Background technology
Thimble is a kind of plastic mould accessory, is the thin bar shape zero that a kind of directly contact product ejects product break away from moulds
Part, thimble are small to the surface breakdown power of plastic products, suitable for there is the situation of precision and surface requirements to ejection position.
The selection principle of die ejector pin is the big thimble of preferred diameter, should be tried one's best less from the specification of thimble, the top of selection
Pin should meet to eject intensity requirement.Wherein the last item will bear larger power due to thimble, sometimes due to vacuumizing phenomenon
Cause thimble stress excess load, cause thimble flexural deformation, once and thimble flexural deformation, then the thimble will cancel, simultaneously
Centre hole on mould may be destroyed, virtually add the cost of manufacture of thimble and mould.
The mould product of this patent, because part is small, thimble requires relatively fine, thimble hole machined on its mould nor
It is often difficult, mould processing technology and mold use effect are directly affected, the problem annoyings my company technique personnel always.
In view of the above-mentioned problems of the prior art, the present inventor combines the design and use of related die field for many years
Experience, it is aided with too strong professional knowledge, there is provided a kind of mould for applying special-shaped thimble, to overcome drawbacks described above.
The content of the invention
For the problems of in the prior art, a kind of mould for applying special-shaped thimble provided by the utility model, leading to
Improvement thimble structure is crossed, it is ensured the intensity of thimble, additionally it is possible to preferably improves the quality of production of product.
To achieve these goals, the technical solution adopted in the utility model is as follows：A kind of mould for applying special-shaped thimble,
Including top plate and bottom plate, the bottom plate is provided with mould leg, and upper die and lower die, the lower mould bottom are provided between the mould leg and top plate
Portion is provided with ejector retainner plate, and the ejector retainner plate is provided with thimble, and the thimble is stretched into inside lower mould；
The upper mould is provided with some upper cavities, and the lower mould is provided with some lower mode cavities, when the upper die and lower die fasten, on
Die cavity and lower mode cavity form product injection molding cavity, and the lower mould is additionally provided with centre hole, and the thimble slides in centre hole；
The thimble includes push rod, and the push rod bottom is provided with supporting plate, and the push rod other end is axially arranged with slot, described
Slot extends radially through push rod and is provided with two screwed holes, is provided with paddle in the slot, the paddle is fixed by the screwed hole.
As preferable technical scheme, each lower mode cavity is equipped with two centre holes, and two centre holes are symmetrical
Set.
As preferable technical scheme, the width of the paddle is less than the diameter of the push rod.
The utility model is beneficial in that：
1. the thimble structure solves the problems, such as small part mould ejection difficulty, the intensity of thimble is not only increased, and
And by paddle and the detachable connection of slot, reduce the cost that thimble is changed.
2. the arrangement of thimble and centre hole further ensures ejection dynamics, the quality of production of product is improved.
