At present, in the oil blanket course of working, the mould die sinking often can appear getting the problem of a difficulty often, need adopt appurtenance help unloading, often for adopting ejector pin analogize material spare. However, when the existing oil seal ejector rod is demolded, the existing oil seal ejector rod is positioned by means of equipment and a mold cavity, the situation that positioning is not accurate can often occur, products are difficult to accurately cooperate with the stress surface of the ejector rod, the problems of ejection damage and framework deformation of the products are caused, the reject ratio is high, the product quality is seriously influenced, and the manufacturing cost is greatly increased.
SUMMERY OF THE UTILITY MODEL
Based on the problem, the utility model aims to provide an oil blanket product demoulding mechanism improves the ejector pin and moves accurate nature, realizes product and the accurate cooperation of ejector pin, improves the problem that the product drawing of patterns warp and ejecting damage.
In order to achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides an oil blanket product demoulding mechanism, its includes forming die and drawing of patterns ejector pin, the last die cavity that is provided with the shaping product of forming die, the die cavity expands the accent outward in forming die's surface formation, the drawing of patterns ejector pin includes pole somatic part and location portion, location portion be with expand accent mouth complex toper outward, pole body portion wears to locate in the location portion and can relative axial motion for location portion and outer accent cooperation back pole somatic part move again, realize accurate ejecting product.
Particularly, the inner wall of the positioning portion is provided with a blocking edge in a protruding mode, the outer wall of the rod body portion is provided with a limiting block in a protruding mode, the limiting block is stopped by the blocking edge, and the rod body portion is limited to be separated from the positioning portion.
Particularly, the top of the rod body part is designed according to the shape profile of the product, and a position giving opening is arranged aiming at the convex part of the product.
In particular, the positioning part is provided with a stop block which is attached to the outer wall of the forming die in a radial protruding mode.
In particular, the top of the locating portion does not touch the product in the cavity.
To sum up, the beneficial effects of the utility model are that, oil blanket product demoulding mechanism has realized the ejector pin drawing of patterns action through unique cooperation structure, has improved the accurate nature and the convenience of ejector pin location, has avoided the condition of drawing of patterns deformation and ejecting damage, has improved product quality and yields, has reduced manufacturing cost.
