Arrange further: described driving means includes being located at the inclined hole of slide block, is located at cope match-plate pattern and is embedded the Angle Pin coordinated with inclined hole to inclined hole.
It is arranged such, by using the cooperation tiltedly caused with inclined hole, is provided that the power that slide block is the most reciprocal, it is to avoid increase complicated driving means, increase die cost.
Arrange further: described slideway is that T-shape is arranged, and the matching form of slide block and slideway closes.
Being arranged such, slideway is T-shape, has the part of lateral Displacement, it is to avoid slide block comes off on slideway.
Arranging further: the bottom of described slideway is provided with the groove worn for Angle Pin, Angle Pin is arranged with groove gap.
Being arranged such, lead during batter post and inclined hole cooperate, lead batter post and can pass inclined hole, arranging of groove can avoid Angle Pin to interfere with slide block.
Arrange further: a wherein sidewall of described plunger tip is conflicted to the sidewall of forming cavity.
Being arranged such, the roof of plunger tip can be conflicted to any position of diapire of side core, and the sidewall retelling plunger tip is conflicted to the sidewall of forming cavity, can the opening of molding side opening side.
Arranging further: described side core is provided with two or more, one of them side core is conflicted to the sidewall of side core, other positions of another or several conflict to core.
Being arranged such, side core has multiple, can adapt to the difform requirement of product with the different position of molding.
Arrange further: and each side core is provided with the second frustum along slide block glide direction, the sidewall of forming cavity is provided with second taper hole suitable with the second frustum.
It is arranged such, and the first frustum and the functional similarity of the second taper hole, when injection, it is ensured that newly-increased side core is conflicted the stability to forming cavity and the precision of the product after later stage injection.
Arranging further: described plunger tip is provided with two or more, one of them is conflicted to the diapire of side core, other positions of another or several conflict to core.
Being arranged such, plunger tip has multiple, can adapt to the difform requirement of product with the different position of molding.
In sum, this utility model has the advantages that this mould is by the plunger tip after improving and side core, plunger tip and side core with the use of, meet product to a great extent porous, shaped, complete under conditions of the said goods needs molding, farthest simplify structure, reduce die manufacturing cost.
