Abstract
The utility model relates to an engine casting device, and in particular relates to an engine cylinder body and cylinder cover core box provided with a quick locking device. The existing core box locking device has potential safety hazards. The core box comprises an upper core box, a lower core box, an equipment bottom plate and a positioning pin, wherein a quick clamp is arranged at the joint of the upper core box and the lower core box, a locking shaft is arranged at the connector of the lower core box, a quick locking hook is arranged on the locking shaft, and a locking pin is arranged on the upper core box. The core box can realize accurate positioning, quick detachment, man-hour reduction and efficiency improvement in the production process.
Description
Technical field
The utility model relates to a kind of engine casting device, is specially a kind of engine core box that is provided with quick-locking device.
Background technology
Casting is one of fundamental technology of modern mechanical manufacturing industry.Casting is mainly by Casting Equipment, and moulds of industrial equipment etc. are for completing machine and the device moulding of casting production process.Casting mould refers to the construction profile in order to obtain part, make in advance the construction profile of part with sand, and then in sand mold, put into mould, so just formed a cavity the same with design of part size in sand mold, in this cavity, pour into a mould mobility liquid, this liquid cools just can form after solidifying and the duplicate part of die shape structure again.Casting Equipment of Machine is exactly that the relevant plant equipment of casting is all belonged to Casting Equipment.Coremaking moulding core-making installation, as moulding machine, sand slinger, core making machine etc.; Sandfalling cleaning equipment, Core making center is a kind of core-making installation automation coremaking, all uses the plant equipment coremaking such as manipulator.
Existing engine core box is made up of two parts of upper core box mechanism and lower core box mechanism, Core making center is in the process of attaching/detaching core box, due to technologic needs, need rise and hang on core box by equipment, by upper core box, upper and lower core box entirety is sling and moved to 4 plates from 3 plates, 3, each two alignment pins on 4 plates, for accurately locating core box, due to this core box about 7000KG that conducts oneself with dignity, core box surrounding is only installed 4 door latch type active grabs, we find in the process of attaching/detaching, because core box deadweight is too high, there is the phenomenon that active grab is opened, there is serious potential safety hazard, in order to address this problem, we have proposed this scheme of increase quick locking hook.
Summary of the invention
There is the problem of potential safety hazard in the utility model, a kind of engine core box that is provided with quick-locking device is provided in order to solve core box locking device.
The technical solution of the utility model, a kind of engine core box that is provided with quick-locking device, structure comprises core box, lower core box, equipment bay and alignment pin, at upper core box, lower core box junction is provided with active grab, interface at lower core box is provided with lock shaft, and lock shaft is provided with quick locking hook, on upper core box, is provided with locking pin.
Compared with prior art, the utility model has increased lock shaft, quick locking hook, locking pin.The quick-locking device of composition, quick locking hook has connected upper and lower core box accurately, makes upper and lower core box very close to each other in lifting process, has effectively protected core box.In process of production can " precise positioning, quick-detachment, reduction man-hour, raise the efficiency ".
brief description of the drawings
Fig. 1 is structural representation of the present utility model
The upper core box of 1-in figure, core box under 2-, 3-equipment bay, 4-alignment pin, 5-lock shaft, 6-active grab, 7-locking pin.
Detailed description of the invention
As schematically shown in Figure 1, a kind of engine core box that is provided with quick-locking device, structure comprises core box 1, lower core box 2, equipment bay 3 and alignment pin 4, at upper core box 1, lower core box 2 junctions are provided with active grab 6, be provided with lock shaft 5 at the interface of lower core box 2, lock shaft 5 is provided with quick locking hook 8, on upper core box 1, is provided with locking pin 7.
It is the round steel of 30mm that described quick locking hook 8 and lock shaft 5 have adopted diameter, and bearing capacity is large, so integral lifting core box safety and reliability.
