A kind of ladder somatotype, the mould structure that push rod is released
The present invention relates to die cast metal mould and plastic injection mould, is a kind of ladder somatotype, the mould structure that push rod is released.
At present, on mould somatotype and ejecting mechanism, have on curved surface somatotype, arc somatotype, plane somatotype, vertical-parting, the ejecting mechanism, have that hydraulic pressure is released, vapour pressure is released, tiltedly pushing tow goes out, push pedal release, rack-and-pinion rotation release; Mechanisms such as guide release are arranged; There are the following defective in these somatotypes and ejecting mechanism, the presentation quality that the product weld mark is big, influence goods, and the goods precision does not reach matching requirements; Difficulty of processing is big when mould design and manufacturing simultaneously; Maintenance, installation and die debugging difficulty when matching with corresponding pressure forming machinery, not directly change the shape of material; Relative position and character, difficulty of qualified product makes it to be shaped.In order to overcome the not enough point of above-mentioned each mould somatotype and ejecting mechanism, I am combined in production line design and manufacturing experience spy for many years provides following a kind of structure to solve this difficult problem.
Summary of the invention
The present invention provides a kind of ladder somatotype, the mould structure that push rod is released.It is to realize like this.As shown in the figure, be to offer overflow launder and air discharge duct by the filling liquid direction in the last filling position of product, moving die insert, dynamic model cage plate and fixed die insert; The cover half cage plate adopts the ladder somatotype, designs push rod again and releases goods; When releasing goods, accomplish, because push rod (3) and push rod (4) are installed in the push pedal (1) by push rod (3) and push rod (4); After accomplishing cast, the mould active and inactive mold is opened, under the effect of former pressure; It is up to promote push pedal (1), push pedal (1) drive push rod (3) and (4) goods from moving die insert (5) outside the launch mode, accomplish whole push.The mould structure that a kind of ladder somatotype push rod is released, it has solved the big difficult problem of product weld mark, can access perfect product requirements; Solved the big problem of difficulty when mould manufactures and designs; Solve the difficult problem of installation and maintenance, debugging inconvenience simultaneously, also reached when matching with corresponding pressure forming machinery, directly changed material shape; Relative position and character, the qualified product that makes it to be shaped is easier to.A kind of ladder somatotype; The mould structure that push rod is released is characterized in that: a kind of ladder somatotype, the mould structure that push rod is released; It is characterized in that: push pedal (1) is communicated with release link (2) and push rod (3) push rod (4); Moving die insert (5) cooperates with push rod (3) and push rod (4) glade plane space, and fixed die insert (6) is installed in the cover half cage plate (8) and with screw and is fastenedly connected on top clamping plate, and dynamic model cage plate (7) is communicated with backing plate and screw with moving die insert (5) matched in clearance afterwards.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified
Sectional side elevation when Fig. 1 is mould matched moulds situation
Fig. 2 is the mould vertical view
Sequence number is represented respectively among the figure:
1--push pedal 2--release link 3--push rod
4--push rod 5--moving die insert 6--fixed die insert
7--dynamic model cage plate 8--cover half cage plate
The specific embodiment:
As shown in the figure: as to be a kind of ladder somatotype; The mould structure that push rod is released; Its specific embodiment is following: it is to fill direction by liquid to offer overflow launder and air discharge duct in the last filling position of goods; Moving die insert (5), dynamic model cage plate (7) adopt step portion profile somatotype to reduce molding product weld marks with fixed die insert (6), cover half cage plate (8) and reduce release power, guarantee the products appearance quality.During release; After the mould active and inactive mold is opened, goods with dynamic model insert (5) move to dynamic model on one side, when die sinking to regularly; Dynamic model moves after stopping; At this moment push rod (3) that former promotion mould push pedal (1) drive is mounted thereto and push rod (4) outside mould moving die insert (5) is gone up launch mode, have guaranteed the requirement that mould release power reduces to goods, the purpose of the goods that improve simultaneously.
