Embodiment Construction

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0036] like figure 1 , figure 2 As shown, the present invention provides a sand core, including a sand core body and a chill iron 6 fixed on the sand core body, the sand core body includes a parent sand core 7 and a sub-sand core 8, and the sub-sand core 8 is embedded in on the parent sand core 7; the cold iron 6 is fixed on the sub-sand core 7.

[0037] The parent sand core can be made by cold box core shooting or 3D printing.

[0038] When using the cold box core shooting method to make the parent sand core, the secondary sand core is a sand body with a thickness of 5-30mm on the sand core body and in contact with the surrounding cold iron. The cold iron can be designed according to the conventional casting process plan. According to the structu...

Abstract

The invention discloses a sand core. The sand core comprises a sand core body and a chilling block fixed on the sand core body. The sand core body comprises a master sand cover and a slave sand core,and the slave sand core is embedded onto the master sand core; the chilling block is fixed on the slave sand core. The invention also provides a mold and a method for manufacturing the sand core.

Description

technical field [0001] The invention relates to a sand core for casting, a cold box core shooting mold for making the sand core, and a method for manufacturing the sand core by using the mold. Background technique [0002] The sand core is a mold that is fixed inside the sand mold to form the cavity in the casting. The sand core itself also needs to be made using a mold. The production of sand core includes traditional cold box core shooting core making and 3D printing sand core making. [0003] In the process of traditional cold box core shooting, the cold iron is usually placed on the lower mold. It is impossible or difficult to install the cold iron on the upper mold. Even if it is used, it can only be placed when the sand core is designed. After the sand core is shot, it is placed and pasted on it. However, due to the draft angle of the sand core made by core shooting, the draft angle, size deviation and flash of the cast cold iron, etc., the cold iron and sand The re...
