Abstract
The present invention relates to injection structure field, specifically disclose mould structure and using method that a kind of nothing realizing high-quality and high-efficiency production ejects, this mould structure, including solid plate, fixed mold core, take-up housing, slider core, mavable module core, moving platen and plastic, fixed mold core is fixed on the framed interior of solid plate, mavable module core is fixed on the framed interior of moving platen, also include push pedal, baffle plate and clamping plate, slider core passes baffle plate, and be pressed on take-up housing by clamping plate, the bore of baffle plate is less than the maximum outside diameter of plastic, and baffle plate is fixed in push pedal.After being molded, when active and inactive mold separates, dynamic model die cavity is the most first made to depart from plastic with cover half die cavity, plastic is finally made to hold tightly in slider core, follow slider core to loose core together, until plastic blocks to the baffle plate being fixed in push pedal, thus realize slider core and depart from plastic, finally fall down due to action of gravity plastic, it is achieved without ejecting the production of full-automatic high-quality and high-efficiency.
Description
Technical field
The present invention relates to injection structure field, the mould structure ejected more particularly, to a kind of nothing realizing high-quality and high-efficiency production and using method.
Background technology
Ejecting after current tubing products is molded, the most frequently used connects several rubbishs in product die joint position exactly, the product while being ejected rubbish by thimble, it connected ejects die cavity simultaneously, then manually rubbish is excised, so product exist rubbish clip print affect outward appearance, and when product sticking to mould power is bigger, rubbish top is difficult to ejecting product, bigger drawback is to waste a large amount of labour forces to go to excise these rubbishs.And another way is thimble directly withstands in the appearance of product, although so removing labour force to go to cut rubbish, but often thimble and slide block have interference, some complex mechanism must be increased on mould go to prevent from interfering, and on Surface Appearance, also have top print, the maintenance rate of mould is higher, and these are all unfavorable for producing.The most more advanced mechanical hand that utilizes exactly takes out product, but equipment cost puts into too big, and product variations is various, and mechanical hand can only set work for specific products, and the suitability is the highest.It is necessary on mould structure to improve for these present situations and solves these problems.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention proposes the mould structure that a kind of nothing ejects, and this mould structure is not on the premise of increasing equipment, cost, it is achieved that after the tubing products demoulding without top print, it is not necessary to cut rubbish, it is possible to high-quality and high-efficiency complete produce.
To achieve these goals, the technical scheme is that
The mould structure that a kind of nothing ejects, including solid plate, fixed mold core, take-up housing, slider core, mavable module core, moving platen and plastic, described fixed mold core is fixed on the framed interior of solid plate, mavable module core is fixed on the framed interior of moving platen, also including push pedal, baffle plate and clamping plate, described slider core passes baffle plate, and is pressed on take-up housing by clamping plate, the bore of described baffle plate is less than the maximum outside diameter of plastic, and baffle plate is fixed in push pedal.
The mould structure of the present invention is not provided with ejecting mechanism, makes product automatically fall down with regard to break away from moulds during loosing core by a baffle plate.
Further, having the logical frame of a peripheral band gradient in the middle of described push pedal, described mavable module core periphery is with inclined-plane, and after matched moulds, to lead to the gradient face of frame suitable with mavable module core face in push pedal.
Further, described push pedal is connected with moving platen by limited screw.
Further, described push pedal is provided with under the product for accepting the plastic that comes off to fall to force dead slot.
Further, described push pedal is connected with solid plate by positioning tie bar.
Further, described baffle plate is screwed in push pedal.
The present invention also proposes the using method of the mould structure that a kind of nothing ejects, and uses the mould structure injection without ejecting, after completing injection, first makes active and inactive mold separate, side core-pulling then.
Compared with prior art, the invention have the benefit that
1) flaws such as this product appearance does not exist thimble print, rubbish clip；
2) simple to the comparison of mould, cost of manufacture and maintenance decrease；
3) without ejecting action, injection cycle can lower the 2-4 second；
4) suitability is strong, and being applicable to various pipe fitting such as straight-through, threeway, elbow etc. has the product of side core-pulling.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further, but embodiments of the present invention are not limited to this.
Such as Fig. 1, the mould structure that a kind of nothing ejects, including solid plate 1, fixed mold core 2, positioning tie bar 3, push pedal 4, limited screw 5, baffle plate 6, clamping plate 7, take-up housing 8, slider core 9, mavable module core 10, moving platen 11 and plastic 12, fixed mold core 2 is fixed on the framed interior of solid plate 1, mavable module core 10 is fixed on the framed interior of moving platen 11, and slider core 9 is through baffle plate 6, and is pressed on take-up housing 8 by clamping plate 7, the bore of baffle plate 6 is less than the maximum outside diameter of plastic 12, and baffle plate 6 is fixed in push pedal 4.Wherein having the logical frame of a peripheral band gradient in push pedal 4, mavable module core 10 periphery is with inclined-plane, and after matched moulds, to lead to the gradient face of frame suitable with mavable module core face in push pedal 4.Between push pedal 4 with moving platen 11, limited location screw 5 is connected, and push pedal 4 is connected by controlled interval pull rod 3 with solid plate 1, and baffle plate 6 is screwed in push pedal 4, and slider core 9, through baffle plate 6, is pressed on take-up housing 8 by clamping plate 7.Slider core 9, mavable module core 10, fixed mold core 2 dress participates in molding plastic 12 after closing.
The mold actions of this reality invention is as follows:
After mould completes injection, when active and inactive mold separates, first opening from A-A die joint, until spacing by limited screw 5 during mavable module core 10 completely disengaged plastic 12, now A-A die joint opens S2.
Then B-B die joint is opened, until fixed mold core 2 completely disengages from during plastic 12 spacing by controlled interval pull rod 3, now B-B die joint opens S1.
Now hydraulic oil cylinder driving take-up housing 8 is loosed core, slider core 9 is i.e. driven to loose core, owing to plastic 12 is still held tightly in slider core 9, and active and inactive mold die cavity has disengaged from plastic 12, then plastic 12 can be followed slider core 9 and moved, until plastic 12 arrives baffle plate 6, gear mouth due to baffle plate 6 is less than the maximum outside diameter of plastic 12, so slider core 9 continues to loose core, plastic 12 then stops following loosing core, and finally makes slider core 9 depart from plastic 12, after loosing core, owing to action of gravity makes plastic 12 fall down, push pedal 4 is forced dead slot do not affect under plastic and fall.
In sum, whole production process does not eject action, the drowned print of product appearance, need not manually cut rubbish, simple in construction, it is achieved the production of high-quality and high-efficiency.
The embodiment of invention described above, is not intended that limiting the scope of the present invention.Any amendment, equivalent and improvement etc. done within the spiritual principles of the present invention, within should be included in the claims of the present invention.
