Detailed Description
In order to make the above features and advantages of the present utility model more comprehensible, embodiments accompanied with figures are described in detail below, but the present utility model is not limited thereto.
Refer to fig. 5 and 7
The utility model provides a pump cover shaping wax matrix structure, includes sprue 1, the lower extreme of sprue is connected with sprue 2, is located the both sides of sprue and is provided with the pump cover die cavity 3 of annular terminal surface orientation sprue respectively, and the front and back side at sprue middle part is provided with vertical runner 4 respectively, the upper and lower portion both sides of sprue are provided with the sprue runner 5 that is connected with the annular terminal surface upper and lower part of pump cover die cavity respectively, the both sides of vertical runner outside end are provided with the vertical runner 6 that is connected with the front and back portion of the annular terminal surface of pump cover die cavity respectively, the both sides of sprue are connected with the slope decurrent runner 7 respectively, the lower extreme of runner has the runner portion 8 of decurrent perpendicularly, the inboard of runner portion is provided with the horizontal runner 9 that is connected with the side terminal surface of pump cover die cavity respectively.
In this embodiment, for better casting, the main runner is in an inverted truncated cone shape. The straight pouring gate is in a quadrangular shape, and is matched with the longitudinal pouring gate to form a cross shape.
In this embodiment, the sprue gate and the longitudinal sprue gate are uniformly arranged on the annular end face of the pump cover cavity along the circumferential direction, so that the annular end portion is uniformly cast.
In this embodiment, the cross sections of the sprue gate and the longitudinal sprue gate are trapezoidal.
In this embodiment, the inclined runner and the runner are both in a quadrangular shape, and the inclined runner and the runner are connected through an arc portion.
In this embodiment, a pair of vertically arranged lateral gates is provided inside the gate portion of each runner. The lateral gate may be cuboid or have a concentric fan configuration (see fig. 7) to better connect with the annular portion of the top surface of the arcuate pump cap portion.
In this embodiment, a chamfer is provided between the annular end portion and the arcuate cover portion of the pump cover cavity, so that molten metal is smoothly transited.
Because the sprue gate sets up in the sprue both sides and add vertical runner and vertical runner gate for the annular tip that the molten metal required more in the pump cover evenly has set up four gates along the circumferencial direction, thereby obtain the casting in time better, and the cooperation has perpendicular runner to cast to the arc lid top surface of pump cover, effectively avoided the situation of leakage because of the molten metal is not closely knit enough between annular tip of pump cover after the shaping and the arc lid, effectively improved the yield of pump cover, also indirectly reduced the loss of molten metal simultaneously, reduced waste material volume, improved the discharge rate.
