Summary of the invention
The utility model has overcome above-mentioned the deficiencies in the prior art, and a kind of bottle moulding that improves is provided, and improves the punching press assembly of processing quality.
The technical solution of the utility model is achieved in that
A kind of bottle moulding punching press assembly, comprise a mouthful mould, mouthful circle and drift, in enclosing, mouth mould and mouth be respectively equipped with for drift turnover mobile the first through hole and the second through hole, the mouth circle is arranged in mouthful mould, the mouth circle is comprised of collar and support circle one, the diameter of support circle is less than collar, collar blocks a mouthful mould, drift is set in the first through hole, the second through hole and the head of drift is exposed to a mouthful mould, mouth mould surrounding convexes with a set ring of embracing pincers in order to connect, along being circumferentially with a plurality of radiating grooves, described radiating groove is along the setting of drift travel direction on set ring.
Because therefore speed during the drift punching press can produce than normal atmosphere, can increase drift pressure like this, in order to reduce drift pressure, as preferably, offer a plurality of air discharge ducts bottom the mouth mould.Thereby gas can be discharged, reduce drift pressure.
In order to improve the concentricity of machine, reduce the instruction time, and it is more smooth that drift is moved, as preferably, in mouth mould bottom punch ingress, the internal diameter of the first through hole is from large to small; In mouth circle bottom punch ingress, the internal diameter of the second through hole from large to small.All form certain tapering in the first through hole, the second through hole ingress like this, thereby drift has been played the effect of guiding.
As preferably, the spacing between Kou Quan bottom and mouthful mould bottom is 0.8~1.1cm.The bulge loop of lower portion of ram can be blocked by a mouthful circle, and the Kou Quan bottom is 0.8~1.1cm with spacing between mouthful mould bottom, thus, has shortened the stroke of drift, is beneficial to product weight control, reduces drift pressure.
As preferably, the top of the support circle on mouthful circle is 0.2~0.3cm with the width of the contact surface of mouthful mould.Thus, the support circle is very little with the contact area of mouthful mould, thereby reduces the die sinking amplitude of mouthful mould,
As preferably, be provided with the first arc slope on the top of set ring, the diameter of the first arc slope increases from top to bottom gradually; Be provided with the second arc slope in the bottom of set ring, the diameter of the second arc slope increases from down to up gradually.The set ring top and the bottom all are provided with arc transition, thereby encounter blank mould in the time of can preventing the upset of seam mould.
Adopted the beneficial effects of the utility model of technique scheme to be:
Along being circumferentially with a plurality of radiating grooves, described radiating groove is along the setting of drift travel direction to the utility model on the set ring of mouth mould; Thereby can the Quick diffusing heat, make and improve the bottle moulding, improve processing quality.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: a kind of bottle moulding punching press assembly, as shown in Figure 1, comprise mouthful mould 1, mouthful circle 2 and drift 3, enclose at mouth mould 1 and mouth and be respectively equipped with the first through hole 4 and the second through hole 5 that supplies the drift turnover mobile in 2, mouth encloses 2 and is arranged in mouthful mould 1, and mouth circle 2 is comprised of collar 6 and support circle 7 one, support circle 7 is positioned at collar 6 upper ends, the diameter of support circle 7 is less than collar 6, and collar 6 blocks mouthful mould 1, thereby a mouthful circle 2 is fixed in mouthful mould 1.
Drift 3 is set in the first through hole 4, the second through hole 5 and the head of drift 3 is exposed to outside mouthful mould 1, mouth mould 1 surrounding convexes with a set ring 8 of embracing pincers in order to connect, along being circumferentially with a plurality of radiating grooves 9, described radiating groove 9 is along drift 3 travel direction settings on set ring 8.
Offer a plurality of air discharge ducts 10 in mouth mould 1 bottom.At mouth mould bottom punch entrance 11 places, the internal diameter of the first through hole 4 from large to small; At mouth circle bottom punch entrance 12 places, the internal diameter of the second through hole 5 from large to small.
Mouthful circle 2 bottoms are 1.0cm with spacing d1 between mouth mould 1 bottom.The top of the support circle 7 on the mouth circle is 0.2cm with the width of the contact surface d2 of mouthful mould 1.The diameter that is provided with the first arc slope 13, the first arc slopes 13 on the top of set ring 8 increases from top to bottom gradually; The diameter that is provided with the second arc slope 14, the second arc slopes 14 in the bottom of set ring 8 increases from down to up gradually.
