Even if 5 each dimensioned precision above-mentioned all control very well, because the part that will coordinate is more, to joining, mould installation requirement is higher, also needs skilled pincers worker just can complete.
6, during lifter ejection, tilted footstock relative motion, oblique top produces torsion, and oblique top angle is larger, and torsion is larger, and oblique top needs flexural strength high.If oblique top angle changes little, the depanning back-off of same size, ejection stroke needs to strengthen, and oblique top length also will increase, and require that oblique flexural strength is higher equally.
7, oblique top is by ejecting action, and ejecting force is comparatively large, is applied to power in oblique top also just very large.If oblique top is blocked, serious to the damage of mould, the even part rejection such as oblique top and tilted footstock.Delay the volume production of mould.
Therefore, for overcoming the deficiency of above-mentioned technology and designing the side force that can reduce above thimble fixed head and Ejector Retainer Plate, eject action and more balance the pneumatic ramp-roof structure of reliable a kind of mould, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide the pneumatic ramp-roof structure of a kind of mould, its device is simple, easy to operate, can reduce the side force above thimble fixed head and Ejector Retainer Plate, eject action and more balance reliably, have extraordinary practical value.
The technical solution adopted for the present invention to solve the technical problems is: the pneumatic ramp-roof structure of a kind of mould, comprise dynamic model, moving platen, thimble fixed head, Ejector Retainer Plate, moving clamping plate, cover half, oblique top, mould pin, it is characterized in that: the pneumatic ramp-roof structure of described mould also comprises cylinder, described moving clamping plate top is provided with Ejector Retainer Plate, Ejector Retainer Plate top is provided with thimble fixed head, between moving platen and thimble fixed head, space defines mould pin, cylinder is provided with in thimble fixed head and Ejector Retainer Plate, one end of cylinder is connected with oblique top, oblique top is through moving platen and dynamic model, the top of oblique top is provided with cover half.
The invention has the beneficial effects as follows:
1, oblique top accessory reduces, and install simple, general technology person just can complete.
2, oblique top length shortens, and oblique top mismachining tolerance is less, also more easily processes.
3, the angle of traditional oblique top can not be done greatly, and pneumatic oblique top angle is just unrestricted, just can design the mould structure of more complex product.
4, the angle of pneumatic oblique top is done greatly, and the ejection stroke completing the back-off demoulding just can shorten, as long as the distance that ejects of mould just considers the demoulding in die sinking direction, and need not calculate oblique top back-off size again, this just likely reduces mold height.
5, on thimble fixed head and Ejector Retainer Plate not in side force, eject action and more balance reliably.
