Through the utility model discloses an implement, reached good result of use: the utility model provides a avoid mould of automobile engine drive end cover eccentric core defect, effectively avoided the eccentric core problem when the drive end cover is cast through setting up two-way location core print on positive, the back pressure board, makes the casting core can fix the accuracy in the mould, eliminates the uneven and deformation phenomenon of wall thickness after the casting shaping, has guaranteed foundry goods size precision and uniformity, has improved the yield and the quality of product.
Drawings
Fig. 1 is a schematic view of the die pressing plate structure of the present invention.
In the figure: 1. the die comprises a die pressing plate, 2, an electromagnetic switch die cavity, 3, a driving gear die cavity, 4, positioning core heads A and 5, positioning core heads B and 6, positioning core heads C and 7 and positioning pin holes.
Detailed Description
The present invention will be described with reference to the accompanying drawings.
As shown in figure 1, the die for avoiding the core deviation defect of the driving end cover of the automobile engine comprises die pressing plates 1 which are arranged in a positive and negative symmetry mode, wherein each die pressing plate 1 is a rectangular pressing plate which is vertically arranged, four driving end cover cavities are uniformly distributed and arranged at the front part of each pressing plate, positioning pin holes 7 are symmetrically arranged at two ends of each driving end cover cavity, and each driving end cover cavity is communicated through a pouring channel; the driving end cover cavity consists of an electromagnetic switch cavity 2 and a driving gear cavity 3, the electromagnetic switch cavity 2 is arranged above the left side of the driving gear cavity 3, and the electromagnetic switch cavity 2 is communicated with the driving gear cavity 3; the driving gear die cavity 3 is an inverted semi-cone, the upper part of the semi-cone is transversely provided with a positioning core print A4, and the lower part of the positioning core print A4 is longitudinally provided with a positioning core print B5; electromagnetic switch die cavity 2 be the semicircle cylinder of inversion, transversely be provided with location core C6 on the upper portion of electromagnetic switch die cavity 2, location core A4 is the level setting with location core C6, location core B5 is vertical setting, the core of two-way location more enough more effectual fixed casting core in level, vertical two directions, the core off-centre problem when avoiding casting.
