Fig. 1 is the structural representation of band gear worm mould provided by the invention;
Fig. 2 is demoulding product structure schematic diagram not after the band gear worm lower mould provided by the invention injection moulding.
The specific embodiment
The invention discloses a kind of band gear worm mould, reduced the taking-up difficulty after the injection moulding of band gear drive worm screw.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is carried out clear, complete description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on embodiments of the invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, Fig. 1 is the structural representation of band gear worm mould provided by the invention; Fig. 2 is demoulding product structure schematic diagram not after the band gear worm lower mould provided by the invention injection moulding.
A kind of band gear worm mould comprises the patrix with screw thread injection molding cavity and the counterdie with gear injection molding cavity first mold insert 1 being set in the patrix that the screw thread injection molding cavity is arranged in first mold insert 1, and what first mold insert 1 rotated is arranged in the patrix.Finish injection moulding work with being with the injection moulding of the screw portion of gear worm by the screw thread injection molding cavity, because the helicitic texture screw rod when the demoulding of this part need produce relative rotation with mould, make and be with the gear worm demoulding smoothly, by this part screw thread injection molding cavity is arranged in rotating first mold insert 1, when the demoulding, first mold insert 1 in the rotatable mould is realized the smooth demoulding of the screw portion of band gear worm, make mould rely on self structure can realize the direct demold of screw thread injecting products, reduced demoulding difficulty.
Be provided with push pedal 5 between the upper die and lower die, push pedal 5 is provided with the connecting portion containing cavity of connecting thread injection molding cavity and gear injection molding cavity.The end of band gear worm is gear structure, therefore when the demoulding, push pedal 5 structures is set, and applies the demoulding thrust to its gear parts simultaneously when the demoulding, thereby is easier to realize the demoulding of product.The containing cavity of the threaded portion of the band gear worm of the present invention by rotation is set, make the demoulding work of product to finish automatically by the die cavity that rotates, avoid the input of equipment in the follow-up knockout course, reduced the use of product stripping parts, reduce mould structure, reduced demoulding difficulty.
In the present invention's one specific embodiment, also be provided with in the patrix and be provided with an end in second mold insert, 2, the second mold inserts 2 and be connected the dispensing creeping road that the other end is connected with the injection molding channel of patrix, second mold insert 2 and the 1 coaxial setting of first mold insert with the screw thread injection molding cavity.The structure of band gear worm is when injection moulding, injection hole is arranged at an end of its threaded portion, because the die cavity of this end is set to rotating first mold insert 1, because rotational structure between first mold insert 1 and the screw thread injection molding cavity, need design the injection hole structure, with the surface effect of product after the assurance injection moulding.Second mold insert 2 is set, dispensing creeping road is flow in the screw thread injection molding cavity by the inside of second mold insert 2, the reason of injection molding material pressure screw thread edge of product after the injection moulding did not produce as blemish such as burrs when second mold insert 2 and the 1 coaxial setting of first mold insert, the rotational structure that makes the mold insert 1 of winning can be because of injection mouldings.The injection hole of patrix arranges centring ring 7 and sprue bush 8, cooperates with the injection hole of injection molding machine.
In the present invention's one specific embodiment, the end that second mold insert 2 is connected with the screw thread injection molding cavity stretches in first mold insert 1, and fits tightly between the two.Second mold insert 2 extend in the screw thread injection molding cavity in first mold insert 1, when first mold insert 1 rotates, all the time fit tightly with first mold insert 1, design by the binding face to the two, guarantee the compactness of screw thread injection molding cavity, avoided being injection-moulded in the blemish that the turntable of screw thread injection molding cavity causes.
In the present invention's one specific embodiment, the lateral wall of second mold insert 2 is provided with the spacing latch 21 that is installed on the patrix.Spacing latch 21 is set, corresponding spacing latch 21 arranges limited impression on the patrix, when 1 rotation of first mold insert makes product stripping, second mold insert 2 can act on the bigger rotation friction of first mold insert 1, spacing latch 21 spacing spacing latch 21 and limited impression are set, second mold insert 2 can guarantee locations of structures more accurately, guarantees the uniformity of Product Status after the repeatedly injection moulding.
In the present invention's one specific embodiment, the 3rd mold insert 3, the three mold inserts 3 are set in the counterdie are fixed on the counterdie by pressing plate, the 3rd mold insert 3 surrounds the gear injection molding cavity with push pedal 5.Pressing plate comprises mold insert pressure strip 4 and to its pressing plate fixed head of fixing 6, offers the storage tank of ccontaining push pedal 5 on the pressing plate fixed head 6.The band gear worm is when the demoulding, upper and lower mould at first separates, the screw portion that first mold insert 1 in the die cavity rotates the band gear worm after the injection moulding that makes in the screw thread injection molding cavity is rotated release, counterdie with the push pedal 5 on it by pushing open on the pressing plate, separate the material space of getting that the back forms the band gear worm between push pedal 5 and the pressing plate, realize product stripping work.In Fig. 2, behind counterdie and the last moulding/demoulding, product 9 is by deviating from the patrix, and push pedal 5 parts such as grade work on the final demoulding of product.
In the present invention's one specific embodiment, be provided with the injection molding cavity of two band gear worms in the band gear screw rod mould., enhance productivity synchronously with the injection moulding of gear worm by two injection molding cavities.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments herein.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
