Abstract

An adjustable-capacity type sand box comprises sand box side plates and a moving type partition board assembly, wherein the moving type partition board assembly comprises a first partition board, a second partition board and a middle connector; one end of the first partition board is connected with the inner wall of one sand box side plate; the other end of the first partition board is connected with one end of the second partition board; the other end of the second partition board is connected with the inner wall of another sand box side plate; a plurality of long round holes are formed in the other end of the first partition board; a plurality of through holes are further formed in one end of the second partition board; and the middle connector is inserted into any through hole of the first partition board and any through hole of the second partition board so as to realize the adjustable connection of the first partition board and the second partition board. The adjustable-capacity type sand box is realized by arranging the moving type partition boards at the four corners of the sand box. An accommodating zone in the middle of the sand box is separated from unoccupied zones at the four corners by the moving type partition boards, so that only the middle accommodating zone is used during the molding of fluid sand. In this way, the capacity of the sand box is adjustable.

Description

technical field

[0001] The invention relates to the technical field of sand casting, in particular to a volume-adjustable sand box. Background technique

[0002] In foundry factories with complex product types and structures, it is not possible to configure special sand boxes for each product, so the substitution of sand boxes is more prominent, especially when using square boxes to produce rotary structure castings. The waste of raw and auxiliary materials such as curing agent is more prominent, resulting in higher production costs.

Embodiment Construction

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the embodiments. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. Ordinary technicians can also obtain other drawings based on these drawings on the premise of not paying creative work.

[0018] see Figure 1 to Figure 5 , the embodiment of the present invention provides a volume-adjustable sand box, including a sand box side plate 10 and a movable partition member 20, the corners of the sand box are formed between the adjacent sand box side plates 10, and the movable The movable partition 20 is arranged at the corner of the sand box to isolate the corner of the sand box. The movable partition 20 includes a first partition 21, a second partition 22, and an intermediate connector 23. One end of the first partition 21 i...
