Abstract

The utility model discloses a casting box, particularly a casting box for casting a gearbox, which comprises a box body and a cover plate, wherein a lateral plate is arranged on the box body; the lower end of the lateral plate is hinged with the box body; the left side and right sides of the lateral plate are fixedly connected with the box body via clamping jaws respectively; each clamping jaw comprises a clamping bar provided with threaded end, a sleeve bar and a clamping chuck; the sleeve bar is in threaded connection with the threaded end of the clamping bar; the clamping chuck is in threaded connection with the sleeve bar; and a flange is formed at the joint part of the box and the lateral plate, so that the clamping jaws can be clamped on the flange of the box and the lateral plate. Accordingly, the utility model can reduce the application cost and improve the production efficiency.

Description

The casting case

Technical field

The utility model relates to a kind of casting case, especially the casting case used of cast gear case.

Background technology

Adopt in the precoated sand casting process at gear-box, the shell mould of gear-box must be put into the casting case, fill precoated sand around in case, pour into a mould then, at present, the casting case all is to rely on import, use cost height, and the casting box structure complexity of general import must reverse during depanning and cast the casing of case and reinstate hanging device, therefore just very loaded down with trivial details, production efficiency is low.

Summary of the invention

The purpose of this utility model is to provide a kind of casting case that reduces use cost and enhance productivity.

In order to achieve the above object, the technical solution of the utility model is: a kind of casting case, comprise casing and cover plate, and have side plate on the casing, the lower end and the casing of side plate are hinged, and fixedly connected with casing by claw respectively in the left and right sides of side plate.

Described claw comprises kelly, loop bar and the chuck with end of thread, and the end of thread of loop bar and kelly is threaded, and chuck is threaded with loop bar.

The connecting portion of described casing and side plate has flange, and claw is clamped on the flange of side plate and casing.

After adopting said structure, owing to have side plate on the casing, the lower end and the casing of side plate are hinged, fixedly connected with casing by claw respectively in the left and right sides of side plate, therefore in casting process, as long as side plate is fixedlyed connected with casing by claw, the bottom of casing is paved with precoated sand, then the gear-box shell mould is put into casing, fill precoated sand with around the shell mould again, just can cast, casing and side plate all adopt general steel to make, simple in structure, reduced use cost, during depanning, as long as claw is unclamped, side plate is opened, and just energy depanning has improved production efficiency.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Shown in Fig. 1,2,3, a kind of casting case comprises casing 1 and cover plate 2, has side plate 3 on the casing 1, and the lower end of side plate 3 and casing 1 are hinged, fixedlys connected with casing 1 by claw 4 respectively in the left and right sides of side plate 3.

Referring to shown in Figure 4, described claw 4 comprises kelly 4-1, loop bar 4-2 and the chuck 4-3 with end of thread 4-1-1, and the end of thread 4-1-1 of loop bar 4-2 and kelly 4-1 is threaded, and chuck 4-3 is threaded with loop bar 4-2.

Shown in Fig. 2,3, described casing 1 has flange 1-1 with the connecting portion of side plate 3, and claw 4 is clamped on the flange 1-1 of side plate 3 and casing 1.

Shown in Fig. 1,2,3,4, when the utility model uses, side plate 3 is fixedlyed connected with casing 1 by claw 4, the bottom of casing 1 is paved with precoated sand, then the gear-box shell mould is put into casing 1, will fill precoated sand around the shell mould again, just can cast, casing 1 and side plate 3 all adopt general steel to make, and be simple in structure, use cost is low, during depanning,, side plate 3 is opened as long as claw 4 is unclamped, just energy depanning has improved production efficiency.
