Abstract
The utility model discloses a simplified rapid secondary ejection mould which comprises an upper mould and a lower mould. A mould cavity for injecting products is arranged between the upper mould and the lower mould, and a contact pin for injecting through holes and a centre for pushing out products are also arranged in the lower mould; a fixed plate is arranged below the lower mould; a push plate, which can move longitudinally, is arranged between the fixed plate and the lower mould; a contact pin push rod is arranged on the push plate; the contact pin is arranged on the contact pin push rod; a cavity is formed in the push plate; a turning block is arranged in the cavity; an inclined plane is arranged at the lower right part of the turning block; a lower locking pin pointing at the inclined plane is arranged on the fixed plate; an upper locking pin pointing at the right side of the turning block is arranged at the lower end of the lower mould; and the lower end of the centre contacts the upper end surface on the left side of the turning block. The simplified rapid secondary ejection mould realizes that processes of mould opening and contact pin pulling after mould opening are combined through reasonable structural modification and particularly the design of the turning block, guarantees the mould opening quality, and has a simple and easy-to-use structure and a high use value.
Description
Technical field
The utility model relates to a kind of mould, and particularly the quick secondary of a kind of simplification ejects mould.
Background technology
The product of some injection mo(u)lding, according to demand at its outside meeting design small through hole, small through hole needs contact pin to realize injection moulding, but because the depanning of contact pin of injection moulding small through hole own is difficult, it is irregular particularly to work as the housing global shape, can further make this constructed products depanning difficulty strengthen, especially can't realize that contact pin extracts simultaneously in depanning, and must design other actuating unit in addition to extract contact pin, in order to make this constructed products make things convenient for depanning, be necessary the structure of mould is carried out new design.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the quick secondary of a kind of simplification to eject mould.
The technical scheme that its technical problem that solves the utility model adopts is:
The quick secondary of a kind of simplification ejects mould, comprise upper die and lower die, be provided with the die cavity for injecting products between the described upper die and lower die, also be provided with in the described counterdie for the contact pin of injection moulding through hole with for the thimble that ejects product, the below of described counterdie is provided with fixed head, be provided with push pedal movable up and down between described fixed head and the counterdie, this push pedal is provided with the contact pin push rod, described contact pin is arranged on the contact pin push rod, have cavity in the described push pedal, be provided with in the described cavity and stir piece, the described lower right of stirring piece is provided with the inclined-plane, described fixed head is provided with the following stop nail that points to the inclined-plane, and the lower end of described counterdie is provided with points to the last stop nail that stirs the piece right side, and the lower end of described thimble contacts with the upper surface, left side of stirring piece.
Be shifted for fear of stirring between piece and the thimble, the described left side of stirring piece has platform, the lower end of described thimble and the contact with platform of stirring piece.
The beneficial effects of the utility model are: this mould is by the rational structure transformation, particularly stir the design of piece, realize that by stirring piece the process of the plug pin after die sinking and the die sinking combines, and has guaranteed the die sinking quality, and simple in structure easy-to-use, have good use value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 stirs the schematic diagram of piece part when injection moulding in the utility model;
Fig. 3 stirs the schematic diagram of piece part when die sinking in the utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2.The quick secondary of a kind of simplification ejects mould, comprise patrix 1 and counterdie 2, be provided with the die cavity 3 for injecting products between described patrix 1 and the counterdie 2, also be provided with in the described counterdie 2 for the contact pin 21 of injection moulding through hole with for the thimble 22 that ejects product, be patrix 1 after die sinking, eject product by thimble 22, but under the less situation of through hole, contact pin 21 is not drawn out easily, and need extract contact pin 21 after patrix 1 is opened again.The below of described counterdie 2 is provided with fixed head 4, be provided with push pedal 5 movable up and down between described fixed head 4 and the counterdie 2, this push pedal 5 is provided with contact pin push rod 23, described contact pin 21 is arranged on the contact pin push rod 23, described push pedal has cavity 51 for 5 li, described cavity is provided with for 51 li and stirs piece 6, the space size requirements of cavity 51 is enough stirred piece 6 activities, the described lower right of stirring piece 6 is provided with inclined-plane 61, described fixed head 4 is provided with the following stop nail 41 that points to inclined-plane 61, inclined-plane 61 guarantees that stop nail 41 can just push up to level stirring piece 6 down, therefore the length of stop nail 41 is unsuitable long down, the lower end of described counterdie 2 is provided with points to the last stop nail 24 that stirs piece 6 right sides, 24 of last stop nails are used for making and stir piece 6 tops to sticking up, the described left side of stirring piece 6 has platform 62, the lower end of described thimble 22 contacts with the platform 62 that stirs piece 6, platform 62 can guarantee thimble 22 and stir between the piece 6 can not misplace, so platform 62 can be designed to cambered surface as required and also can realize equal effect.
When real work, with reference to Fig. 2, when injection moulding, push pedal 5 descends on fixed head 4, and the following stop nail 41 of fixed head 4 withstands and stirs piece 6 and make and stir piece 6 and lie in 51 li of cavitys; With reference to Fig. 3, after patrix 1 is opened, when push pedal 5 rises to counterdie 2 lower surfaces, the last stop nail 24 of counterdie 2 is stirring piece 6 tops to sticking up, stir 62 on the platform in piece 6 left sides thimble 22 jack-up, make thimble 22 eject product, at this moment, contact pin push rod 23 cooperates thimble 22 to make product finish the demoulding to contact pin 21 applied thrusts again.
According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
Through facts have proved, the utility model is by stirring the design of piece 6, namely grasp the process that thimble 22 ejects product and contact pin 21 disengaging products by stirring piece 6, the process of the plug pin 21 after realization die sinking and the die sinking combines, guaranteed the die sinking quality, and simple in structure easy-to-use, have good use value.
