Description
Technical field
The present invention relates to molding field, specifically, the present invention relates to a kind of mould casting corner core pulling method and dress
Put, the mould casting is extracted out after being molded with corner core-pulling device, more particularly it relates to a kind of new mould casting
With corner core pulling method and device, the mould casting is used in particular for the mould casting of automobile lamp with corner core pulling method and device
Modeling.
Background technology
In the past, when mould casting part intermediate demand core pulling, for example, it is desired on the mould casting part
Form the situation when concave-convex structure such as specific groove, side and additional member, traditional way be exactly using outer core-pulling device or
Ramp-roof structure.
Die space is taken needed for outer core-pulling device more, and ramp-roof structure is then only applicable to less stroke and can not expired
Foot die sinking direction is more than 15 degree of situation.In this regard, conventional only two roads of mentality of designing can be walked.First, for using a mould one
The structure of chamber；Secondly the injection molding machine to use the big one-level of tonnage, because the bigger mould table top that can be carried of tonnage is also bigger.On
Stating both of which causes no small waste.
Particularly, in mould casting auto parts machinery, for example, during mould casting Automobile Lamp, in order to meet vehicle body individual character
The modeling requirement of change, particularly in the lens of mould casting headlamp, in order to meet headlamp lens moulding renewal
While, the clearance requirement of Metal Sheets for Body-manufacturing is also met, the mould casting of lens is often required for setting other core pulling dress
Put to carry out.The increase of core-pulling device, the utilization rate for die space also just proposes higher requirement.
For example, as described previously for the situation of mould intermediate demand core pulling, traditional way is exactly using outer core-pulling device
Or ramp-roof structure.And occupancy die space needed for outer core-pulling device is more, ramp-roof structure is then only applicable to less stroke and nothing
Method meets the situation that die sinking direction is more than 15 degree, and conventional only two roads of mentality of designing can be walked.First, to use a cavity per mould
Structure；Secondly the injection molding machine to use the big one-level of tonnage, because the bigger mould table top that can be carried of tonnage is also bigger.It is above-mentioned
Both of which causes the no small waste of the utilization rate, equipment and its cost of die space and rack space.
