Embodiment Construction

[0022] In order to illustrate the technical solutions of the present invention more clearly, the embodiments of the present invention will be described in detail according to the accompanying drawings. Obviously, the accompanying drawings in the following description are typical embodiments of the present invention. On the premise of creative work, other drawings can also be obtained from these drawings.

[0023] This embodiment is a two-box molding casting process, and all the cavity structures of the casting are in the lower mold.

[0024] The alternative press box device according to the present invention includes a cover core 3 , a clamping plate 7 and a backing plate 9 .

[0025] like figure 2 The shown cover core 3 is composed of a cover core main body 3A and a cover core core head 3B. A part of the casting cavity is arranged on the cover core main body 3A. After the casting cavities on the mold 11 cooperate with each other, a completed casting cavity is formed; the c...

Abstract

The invention discloses a box pressing device with a replaceable upper mold, and a use method thereof. The box pressing device is applicable to the technical field of sand mold casting, and aims at solving the problems of high sand-iron ratio, high raw material waste and high production cost caused due to that an upper mold only plays the role of box pressing when a mold is completely located in alower mold. The box pressing device comprises a cover core, a clamping plate and a backing plate, wherein the cover core is matched with the lower mold to form a complete cavity of a casting; and theclamping plate and the backing plate are used for realizing the role of box pressing. With the adoption of the box pressing device disclosed by the invention, production for the upper mold is avoided, the production cost is lowered, the waste of production raw materials is reduced, and the production sand-iron ratio of the casting with the cavity located in the lower mold is greatly lowered.

Description

technical field [0001] The invention relates to an upper-type press box link in a box closing process of casting, in particular to a press box device that can replace the upper-type box. Background technique [0002] Sand casting is generally two-box and three-box. The two-box mold is composed of upper and lower boxes, and the three-box mold is composed of upper, middle and lower boxes. While this is easier to produce, it requires more sand to be used, increasing the card box workload. For castings in which all cavities (including gating and riser systems) are located in the lower box or the middle and lower boxes, the function of the upper box is only to press the middle box and the lower box after the core is assembled to prevent the sand box from acting on the molten metal. Float up and down. In the case that the cavity structure of this casting is located in the lower box (lower mold), the use of the upper box press box will cause problems such as high casting producti...
