Description

TECHNICAL FIELD

[0001] The utility model relates to the mould design field especially is related to a quick dismounting device for automobile metal fitting mould. BACKGROUND

[0002] After automobile metal fittings are formed in the mould, the common demoulding mode is to use the ejector pin to push out, which needs to use the ejector pin plate to drive the ejector pin to ascend, so that the upper ends of the plurality of ejector pins abut against the bottom side edge of the automobile metal fitting, and then the formed automobile metal fitting is pushed out of the mould.

[0003] In the above scheme, since the temperature of the automobile metal fitting is very high immediately after forming, directly pushing out the automobile metal fitting with the ejector pin is easy to leave the ejector pin mark at the position of the ejector pin of the automobile metal fitting, especially for the die casting mould, it is necessary to wait until the metal liquid cools to a certain extent before using the ejector pin to push out, otherwise it is very likely to damage the bottom side edge of the automobile metal fitting, therefore, it is necessary to design a pouring mould without the ejector pin mark and capable of demoulding more quickly.

[0004] In view of the above defects, the prior art (publication number: CN205393499U, publication date: 2016.07.27) discloses a mould structure without ejector pin mark for alloy metal frame die casting, which cancels the original design of the product ejector pin inside the cavity, and designs the ejector pin on the runner and the plurality of ladles outside the product, so as to push out the die casting product and make the surface of the product without the ejector pin mark.

[0005] In the above scheme, since the ejector pin is pushed out of the product through the runner and the plurality of ladles outside the product, the water gap between the runner, the ladle and the product needs to be designed to be relatively large, so as to ensure the effective pushing out of the product, but the product with the large water gap is difficult to clean the water gap subsequently, which leads to low production efficiency and the surface of the product may be damaged when cleaning the water gap; in addition, since the scheme is not directly pushed out of the product, the demoulding may not be complete, which affects the quality of the product.
