Description
Technical field
The present invention relates to a kind of arc core-pulling mechanism of injection mold.
Background technology
Plastics injection mould is the instrument for producing plastic products, using widely.In plastic products injection moulding, by
Have indent, side channel, side opening etc. in the inside of some plastic products, need to set mold cores and in plastic part after shaping
Mold cores are taken out by way of core pulling.
Because consumer is increasingly lifted to the quality requirement of product, in order to increase plastic product various aspects of performance, it is necessary to
By the separately part progress integrated injection moulding production of shaping assembling originally, this also just increases difficulty of processing.For example, wide-angle
Plastic bend tube or the bend pipe with straight length, conventional meanses are to take multisection type to be molded respectively to be assembled again, it is now desired to
Bend pipe is integrally formed, the arc core-pulling of the wide-angle of complexity is just designed among these.Prior art after completion of the injection-moulding, mould
The mold insert of tool can in itself be interfered when extracting out with die or moulding, lead to not the smoothly demoulding.The side of plastic mould core-extracting
Formula also has a lot, but less for the extraction mode with radian hole, be badly in need of in the industry it is a kind of can facilitate, stably, reliable arc
The drawing mechanism of core.
The content of the invention
In order to overcome the above-mentioned deficiency of prior art, the present invention provides a kind of arc core-pulling mechanism of injection mold.
The present invention solve its technical problem technical scheme be：A kind of arc core-pulling mechanism of injection mold, including mould
It is provided with to be provided with punch-pin, described lower mold base in upper mold base and lower mold base, described upper mold base in main body, the die main body and is provided with
Cavity plate, after described upper mold base is with described lower mold base matched moulds, the die cavity formed between described punch-pin and described cavity plate,
Provided with the first straight mold insert in described cavity plate, described lower mold base is provided with the first sliding block measured, the first described cunning
Block is connected with the first described mold insert；
The second mold insert provided with bending in described punch-pin, described upper mold base is provided with the second sliding block measured, described second
The front end of sliding block is provided with first connecting rod, and the upper end of second mold insert is hinged with second connecting rod, described first connecting rod with it is described
Second connecting rod be hinged；
The front end of first mold insert is connected with the lower end of second mold insert.
Further, the upper surface of second mold insert offers and limited block is provided with spacing hole, described upper mold base, described
The described spacing hole of limited block insertion in.
Further, fixed support is additionally provided with described upper mold base, the second described mold insert is cut with scissors with described fixed support
Connect.
Further, the rear end of second sliding block is provided with oil cylinder core-pulling mechanism.
Further, the second described mold insert semicircular in shape.
The beneficial effects of the present invention are：Core pulling is distinguished by the first mold insert and the second mold insert, and using first connecting rod and
Second connecting rod constitutes secondary connecting rod pulled core structure so that the second mold insert of bending is eliminated and injection-molded finished and upper mould in core pulling
The interference of benevolence, it is ensured that the second mold insert is smoothly stripped, so as to realize being integrally formed for wide-angle bend pipe, or even can produce bend pipe with
The integrally formed product of remaining housing.

Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Set in 1~Fig. 5 of reference picture, a kind of arc core-pulling mechanism of injection mold, including die main body 1, the die main body 1
Have to be provided with punch-pin 4, described lower mold base 3 in upper mold base 2 and lower mold base 3, described upper mold base 2 and be provided with cavity plate 5, when described
After upper mold base 2 and the described matched moulds of lower mold base 3, the die cavity formed between described punch-pin 4 and described cavity plate 5, described is recessed
Provided with the first straight mold insert 6 in mould 5, described lower mold base 3 is provided with the first sliding block 7 measured, described the first sliding block 7 with
The first described mold insert 6 is connected；
The second mold insert 8 provided with bending in described punch-pin 4, described upper mold base 2 is provided with the second sliding block 9 measured, described
The front end of second sliding block 9 is provided with first connecting rod 10, and the upper end of second mold insert 8 is hinged with second connecting rod 11, described first
Connecting rod 10 is hinged with described second connecting rod 11；
The front end of first mold insert 6 is connected with the lower end of second mold insert 8.
Due to being integrally formed the requirement of injection bend pipe 16, it is preferred that the described semicircular in shape of the second mold insert 8, so as to second
Mold insert 8 can be extracted out smoothly.
In the present embodiment, the upper surface of second mold insert 8 is offered in spacing hole 12, described upper mold base 2 provided with limit
Position block 13, described limited block 13 is inserted in described spacing hole 12.Because the second mold insert 8 is the knot of taking secondary connecting rod to extract out
Structure, second connecting rod 11 is connected with the second mold insert 8 by way of being hinged, therefore shake easily occurs in production and mobile, is made
Rise into moulding percent defective.By the cooperation of spacing hole in this implementation 12 and limited block 13, it can play good to the second mold insert 8
Good position-limiting action, so as to ensure the smooth production of moulding.
In the present embodiment, fixed support 14 is additionally provided with described upper mold base 2, the second described mold insert 8 is consolidated with described
Fixed rack 14 is hinged.It is preferred that, the fixed support 14 is attached to the both sides of the second mold insert 8, can both play the second mold insert 8 of connection
Effect, the displacement on the left and right direction of the second mold insert 8 can also be limited.
In the present embodiment, the rear end of second sliding block 9 is provided with oil cylinder core-pulling mechanism 15.Due to the core pulling of the second mold insert 8
Away from larger, take oil cylinder core-pulling mechanism 15 to play saving raw material, shorten the effect of molding cycle.
The present invention by the first mold insert and the second mold insert in use, distinguish core pulling, and use first connecting rod and second connecting rod
Constitute secondary connecting rod pulled core structure so that the second mold insert of bending is eliminated in core pulling to be done with injection-molded finished and upper cores
Relate to, it is ensured that the second mold insert is smoothly stripped, so as to realize being integrally formed for wide-angle bend pipe, or even bend pipe and remaining shell can be produced
The product of body by integral forming.
