Demoulding product structure schematic diagram not after the band gear worm lower mould injection moulding that Fig. 2 provides for the utility model.
The specific embodiment
The utility model discloses a kind of band gear worm mould, reduced with the taking-up difficulty after the injection moulding of gear drive worm screw.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the structural representation with gear worm mould that Fig. 1 provides for the utility model; Demoulding product structure schematic diagram not after the band gear worm lower mould injection moulding that Fig. 2 provides for the utility model.
A band gear worm mould, comprises the patrix with screw thread injection molding cavity and the counterdie with gear injection molding cavity, and the first mold insert 1 is set in patrix, and screw thread injection molding cavity is arranged in the first mold insert 1, and what the first mold insert 1 rotated is arranged in patrix.The injection moulding of the screw portion with gear worm is completed to injection moulding by screw thread injection molding cavity works, because this part helicitic texture screw rod when the demoulding need to produce relative rotation with mould, make to be with the gear worm demoulding smoothly, by this part screw thread injection molding cavity is arranged in rotating the first mold insert 1, when the demoulding, the smooth demoulding that the first mold insert 1 in rotatable mould is realized with the screw portion of gear worm, make mould rely on self structure can realize the direct demold of screw thread injecting products, reduced demoulding difficulty.
Between upper die and lower die, be provided with push pedal 5, in push pedal 5, be provided with the connecting portion accommodating cavity of connecting thread injection molding cavity and gear injection molding cavity.End with 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, thereby be easier to realize the demoulding of product when the demoulding.The utility model is by arranging the accommodating cavity of the threaded portion with gear worm of rotation, the demoulding work of product can be completed automatically by the die cavity rotating, avoid the input of equipment in follow-up knockout course, reduced the use of product stripping parts, reduce mould structure, reduced demoulding difficulty.
In the utility model one specific embodiment, in patrix, be also provided with the second mold insert 2, in the second mold insert 2, be provided with one end and be connected with screw thread injection molding cavity, minute injection molding channel that the other end is connected with the injection molding channel of patrix, the second mold insert 2 and the first mold insert 1 coaxially arrange.With the structure of gear worm when the injection moulding, injection hole is arranged at one end of its threaded portion, because the die cavity of this end is set to rotating the first mold insert 1, due to rotational structure between the first mold insert 1 and screw thread injection molding cavity, need to design injection hole structure, to guarantee the surface effect of product after injection moulding.The second mold insert 2 is set, divide injection molding channel to be flow in screw thread injection molding cavity by the inside of the second mold insert 2, the second mold insert 2 and the first mold insert 1 coaxially arrange, and when the rotational structure that makes the first mold insert 1 can be because of injection moulding, the reason of injection molding material pressure does not produce as blemish such as burrs to the screw thread edge of product after injection moulding.The injection hole of patrix arranges centring ring 7 and sprue bush 8, coordinates with the injection hole of injection molding machine.
In the utility model one specific embodiment, one end that the second mold insert 2 is connected with screw thread injection molding cavity stretches in the first mold insert 1, and fits tightly between the two.The second mold insert 2 extend in the screw thread injection molding cavity in the first mold insert 1, when the first mold insert 1 rotates, all the time fit tightly with the first mold insert 1, by the binding face to the two, design, 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 utility model one specific embodiment, on the lateral wall of the second mold insert 2, be provided with the spacing latch 21 being installed on patrix.Spacing latch 21 is set, on patrix, corresponding spacing latch 21 arranges limited impression, when the first mold insert 1 rotation makes product stripping, the second mold insert 2 can act on the larger rotation friction of the first mold insert 1, spacing latch 21 spacing spacing latch 21 and limited impression are set, the second mold insert 2 can guarantee locations of structures more accurately, the uniformity of Product Status after assurance Multi-step injection molding.
In the utility model one specific embodiment, the 3rd mold insert 3, the three mold inserts 3 are set in counterdie and by pressing plate, are fixed on counterdie, the 3rd mold insert 3 surrounds gear injection molding cavity with push pedal 5.The pressing plate fixed head 6 that pressing plate comprises mold insert pressure strip 4 and it is fixed, offers the storage tank of accommodating push pedal 5 on pressing plate fixed head 6.Band gear worm is when the demoulding, first upper and lower mould separates, the first mold insert 1 in die cavity rotates and makes the screw portion with gear worm after the injection moulding in screw thread injection molding cavity be rotated release, counterdie by the push pedal on it 5 by pushing open on pressing plate, between push pedal 5 and pressing plate, separately rear formation, with the feeding space of gear worm, realizes product stripping work.In Fig. 2, after counterdie and upper moulding/demoulding, product 9 is by deviating from patrix, and push pedal 5 parts such as grade work on the final demoulding of product.
In the utility model one specific embodiment, with being provided with two in gear worm mould with the injection molding cavity of gear worm.By two injection molding cavities, synchronously with the injection moulding of gear worm, enhance productivity.
In this description, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
