Description
Technical field
The present invention relates to a kind of plastic object forming method more than injection locomotive wall size, refer in particular to a kind of mould that can be sized more than injection locomotive wall size, and the method that molding can be stablized.
Background technology
Existing ejaculator mainly has clamping mechanism, ejecting mechanism; this clamping mechanism has fixing car wall, moveable cart wall; and on fixing car wall, moveable cart wall, it is respectively provided with fixed bolster plate, active side template; and it is respectively provided with master mold, male model in fixed bolster plate, active side template; its forming step makes this moveable cart wall be engaged locked mode action with fixed bolster plate by suitable pressure by power source band command of execution active side template displacement again, then makes ejecting mechanism that mould is penetrated fused raw material molding.
The ejaculator fixed bolster plate of this existing injection method, active side template area are respectively smaller than fixing car wall, moveable cart wall, thus the clamp force of this administration activities side template can make fixed bolster plate, active side template stably to engage, and unlikely in time bearing injection pressure can there be flash or the injection bad situation of end product quality.
But the size of the mould of this shoot mode and finished product is necessarily limited to the fixing car wall of ejaculator, moveable cart wall size, although according to more than fixed bolster plate after locked mode during the mould of aforementioned car wall size, active side template central authorities can have setting clamp force, but easily cause this can not bear injection pressure beyond position and produce flash and the injection the best disappearance of quality because clamp force is not enough beyond Che Bi position, thus existing shoot mode is when must possessing and fix more than this thing by molding one object, the ejaculator of moveable cart wall size, cause forming machine to have equipment cost and increase disappearance.
Additionally, at present ejaculator is limited to cost and industry applications has commercially viable full-size, cause buy in practice this largest ejaculator still can not molding fix beyond this ejaculator, the product situation of moveable cart wall size.
Summary of the invention
It is an object of the invention to provide a kind of plastic object forming method more than injection locomotive wall size, it can have the forming method of good forming stability and end product quality.
In order to reach above-mentioned purpose, the solution of the present invention is:
A kind of plastic object forming method more than injection locomotive wall size, it comprises the following steps:
A ejaculator is fixed, be respectively provided with width or length on moveable cart wall more than fixing car wall, the fixed bolster plate of moveable cart wall, active side template, and arranges in fixed bolster plate, active side template more than fixing car wall, moveable cart wall width or the mould of length；
B fixed bolster plate, active side template install auxiliary lock die device beyond fixing car wall, the extending part of moveable cart wall；
C moveable cart wall makes mould locked mode towards fixing car wall force；
D auxiliary lock die device action makes the extension position pressurization locked mode of fixed bolster plate, active side template；
E injection machine filling molding.
Above-mentioned step B fixed bolster plate, active side template form extension beyond fixing car wall, moveable cart wall position; this auxiliary lock die device is located at this extension position again; and include multiple locking mechanism and multiple clamping mechanism; wherein this locking mechanism is located on a side template; having holder, this holder has deployable, the clip slot of condensation；This clamping mechanism is located in opposite side template, has mode locking cylinder and locked mode post, and this locked mode post is fixed on the corresponding aforementioned clip slot of side template；This mode locking cylinder provides locked mode post clamp force again；The holder clip slot making again locking mechanism is deployed condition, and this step C makes moveable cart wall towards fixing car wall displacement matched moulds, make correspondence fix, the die location of moveable cart wall has the original clamp force of ejaculator, during mould assembling action, this locked mode post is extended through the clip slot position of holder again, make again clip slot clamping locked mode post so that mode locking cylinder force makes the fixed bolster plate of extension position, active side template have clamp force.
Above-mentioned locking mechanism is located in active side template, and clamping mechanism is located on fixed bolster plate again.
Above-mentioned locking mechanism also includes locking cylinder, this holder has deployable, the upper and lower fixture block of condensation, and these upper and lower fixture block central authorities have clip slot, and arrange the blocking part on concavo-convex surface in fixture block, this locking cylinder is located on holder, drives the expansion of upper and lower fixture block, condensation action；The locked mode post front outer of this clamping mechanism arranges the holding section engaged with aforementioned blocking part convex-concave surface again, and mode locking cylinder provides locked mode post condensation direction clamp force.
After using said structure, the fixed bolster plate of step A in the present invention, active side template width or length are respectively greater than fixing car wall, the width of moveable cart wall or length, and have more than fixing car wall, the mould of moveable cart wall width, this step B fixed bolster plate, active side template is beyond fixing car wall, moveable cart wall position forms extension, this auxiliary lock die device is located at this extension position, and include multiple locking mechanism, multiple clamping mechanisms, wherein this locking mechanism is located in active side template, there is holder, locking cylinder, this holder has deployable, be condensed is upper, lower fixture block, on this, lower fixture block central authorities have clip slot, and the blocking part on concavo-convex surface is set in fixture block, this locking cylinder is located on holder again, can drive, lower fixture block launches, condensation action；This clamping mechanism is located on fixed bolster plate, has mode locking cylinder and locked mode post, and this locked mode post externally protrudes out in outside fixed bolster plate, and the corresponding aforementioned clip slot in axle center, arranges again the holding section that can engage with aforementioned blocking part convex-concave surface in front outer；This mode locking cylinder can provide locked mode post condensation direction clamp force；This step C makes moveable cart wall towards fixing car wall displacement matched moulds again, make corresponding fixing car wall, moveable cart wall has die location can have the original clamp force of ejaculator, during mould assembling action, this locked mode post can be extended through the clip slot position of holder again, the blocking part making holder can firm with the holding section of locked mode post engage, D step the most of the present invention makes mode locking cylinder force that the active side template correspondence fixed bolster plate direction of extension position can be made to have suitable clamp force, thus the present invention can stablize matched moulds by the clamp force of auxiliary lock die device, make to be not result in that mould correspondence extending part is equipped with flash or penetrates bad situation by this injection pressure during E step injection molding, can promote and preferably penetrate end product quality, and make the mould of the present invention and finished product can not yield to ejaculator size to have the preferable suitability and industry applications.
