Description

Pump cover convenient for sand removal Technical Field The application relates to the field of pump covers, in particular to a pump cover convenient for sand removal. Background The cooling cavity is formed on the pump cover body in the circumferential direction, and in the processing process of the pump cover body, sand is removed from the cooling cavity after the pump cover is formed, so that two sand removal holes can be reserved in the manufacturing process of the existing pump cover, and sand in the cooling cavity is discharged through the sand removal holes. Then because the pump cover sand removal hole among the prior art is perpendicular setting with the cooling chamber, when removing sand through sand removal hole, can exist the dead angle, lead to hardly getting rid of the molding sand in the cooling chamber totally. Disclosure of utility model In order to improve the thoroughness of sand removal, the application provides a pump cover convenient for sand removal. The application provides a pump cover convenient for sand removal, which adopts the following technical scheme: The utility model provides a pump cover convenient to sand removal, includes first lid and second lid, the cooling chamber has been seted up on the first lid, the sand removal hole in the cooling chamber of intercommunication has been seted up to the terminal surface of first lid, second lid demountable installation is in order to carry out the shutoff to the sand removal hole on first lid. Through adopting above-mentioned technical scheme, cooling chamber and degritting hole are on a straight line, the dead angle that exists when reducing the sand removal to be convenient for get rid of the molding sand of cooling chamber, improve the efficiency and the thoroughness of sand removal, install the second lid on first lid after the clearance is accomplished, thereby carry out the shutoff to degritting hole and cooling chamber. Optionally, the sand removal hole is arc-shaped, the cross section of sand removal hole and the cross section looks adaptation of cooling chamber make the width of sand removal hole the same with the width of cooling chamber. By adopting the technical scheme, the cross section of the sand removal hole is matched with the cross section of the first annular groove, so that the sand removal dead angle can be further reduced. Optionally, the side wall of the cooling cavity far away from one side of the sand removal hole is in an arc shape. Through adopting above-mentioned technical scheme, the lateral wall that sand removal hole one side was kept away from to the cooling chamber is the arc setting to can reduce the sand removal dead angle.
