Abstract
The invention relates to an internal-thread forming mechanism with an ejecting plate, which is applied to a die. The internal-thread forming mechanism comprises the ejecting plate, at least four thimbles and at least four inserts, wherein the ejecting plate is arranged in a core insert of the die, the ejecting plate is provided with two guide pins; one ends of the thimbles are in contact with the ejecting plate; one ends of the inserts are provided with threads and are in contact with a product, and the other ends of the inserts are provided with static pressure bearings. The internal-thread forming mechanism has the advantages of simple structure and reduced cost of the die.
Description
[technical field]
The present invention relates to a kind of mechanism of moulding internal thread, be specifically related to a kind of top board moulding internal threaded mechanisms.
[background technology]
When product had female thread structure, as cosmetics plastic casing product, auto parts series products etc., female thread structure needed the mould of plastics moulding.Existing moulding internal threaded mechanisms common mechanism is taken out concentric mechanism for the multiple-threaded screw gear.
See also Fig. 1, shown in Figure 2, it illustrates the structural representation of existing moulding internal threaded mechanisms, the floor map of existing moulding internal threaded mechanisms respectively, and this moulding internal threaded mechanisms is applied in the mould, and it comprises:
Go into son 13 for four, this is gone into son 13 1 ends and is provided with screw thread and contacts with product 5, and this is gone into 13 of sons and is provided with two balance gears 16;
Two multiple-threaded screws 12 are respectively equipped with a gear 14 on this multiple-threaded screw 12, the number of teeth of this gear 14 is gone into sub 13 number of threads and matched with above-mentioned, and this gear 14 is provided with hydrostatic bearing 15.
During the mould die sinking, mother module core 10 separates with male model benevolence 11, multiple-threaded screw 12 driven gears 14 rotate and move to the direction at mother module core 10 places, gear 14 drives son 13 rotations, go into son 13 to the rightabouts motion of multiple-threaded screw 12 motion and from product 5, deviate from, product 5 is ejected, then next mould product of mould matched moulds reshaping.This moulding internal threaded mechanisms complex structure and die cost height.
In view of this, be necessary to provide a kind of top board moulding internal threaded mechanisms in fact, the simple in structure and die cost of this top board moulding internal threaded mechanisms has obtained reduction.
[summary of the invention]
Therefore, the purpose of this invention is to provide a kind of top board moulding internal threaded mechanisms, the simple in structure and die cost of this top board moulding internal threaded mechanisms has obtained reduction.
In order to achieve the above object, top board moulding internal threaded mechanisms of the present invention is applied in the mould, and this top board moulding internal threaded mechanisms comprises:
One liftout plate, it is located in the mould male model benevolence, and this liftout plate is provided with two pilot pins;
At least four thimbles, this thimble one end contacts with above-mentioned liftout plate;
Go into son at least four, this is gone into a sub end and is provided with screw thread, and the other end is provided with hydrostatic bearing, and an end that is provided with screw thread contacts with product.
Compared to prior art, the simple in structure and die cost of top board moulding internal threaded mechanisms of the present invention has obtained reduction.

[specific embodiment]
See also Fig. 3, shown in Figure 4, it illustrates the structural representation of top board moulding internal threaded mechanisms of the present invention, the floor map of top board moulding internal threaded mechanisms of the present invention respectively.
Top board moulding internal threaded mechanisms of the present invention is applied in the mould, and this mould is the multi-point mould structure in present embodiment, and this top board moulding internal threaded mechanisms comprises:
One liftout plate 22, it is located in the mould male model benevolence 21, and this liftout plate 22 is provided with two pilot pins 26, and these pilot pin 26 1 ends contact with mould male model benevolence 21;
Four thimbles 23, these thimble 23 1 ends contact with above-mentioned liftout plate 22;
Go into son 24 for four, this is gone into son 24 1 ends and is provided with screw thread, and an end is provided with hydrostatic bearing 25, and an end that is provided with screw thread contacts with product 50.
See also Fig. 5, shown in Figure 6, its schematic diagram, one embodiment of the invention that illustrates one embodiment of the invention product is respectively gone into the schematic diagram of son.In present embodiment, during the mould die sinking, mother module core 20 separates with male model benevolence 21, and four thimble 23 synchronous jack-up liftout plates 22, liftout plate 22 drive products 50 motions, goes into son 24 rotation and deviating from from product 50 under the effect of hydrostatic bearing 25; When mother module core 20 separates fully with male model benevolence 21, take out product 50; Thimble 23 is with liftout plate 22 returns and drive pilot pin 26 returns, mould matched moulds; Continue next mould product of moulding behind the mould matched moulds.
Compared to prior art, the simple in structure and die cost of top board moulding internal threaded mechanisms of the present invention has obtained reduction.
