Abstract
The utility model discloses a box tightening hook device which comprises a positioning bracket. The positioning bracket is hinged with an oil cylinder by a connecting base, the front end of a piston rod of the oil cylinder is hinged with a rotating block which is articulated at a fixed supporting point, and one end of the rotating block is extended to form a poking rod. The box tightening hook device indirectly controls the opening and closing of a box tightening hook by the reciprocating moving of the oil cylinder; when meeting with a sand box hook, the box tightening hook can lead the box hook to be further closed and locked. The box tightening hook device effectively solves the problem that melted iron flows out due to that upper and lower sand boxes cannot be tightened; moreover, the finished product rate of castings is increased, the operation by an operator is safer, and the reliability is high. Compared with the prior art, the box tightening hook device makes obvious progress.
Description
Technical field
The utility model relates to a kind of tight tight case hook device of drag box case hook lock of assisting.
Background technology
In the casting and molding transfer matic, before carrying out the cast program, it is further fixing that the last drag box that lumps together also will use the case hook lock to carry out, the case hook lock of sandbox can cause when tight the molten iron that in casting process, melts from flow out the slit in the middle of the drag box, the molten iron that flows out not only causes the accident of injury to personnel easily and causes scrapping of foundry goods, and also easy to clean not of molten iron slag.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of tight case hook device, and it can be to not locking or lock the correct locked position of sandbox case hook playback not in place.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of tight case hook device comprises a location support, and described locating support is connected with an oil cylinder through connecting pedestal, and the moving block hinge that the piston rod front end and of described oil cylinder is hinged on a fixed pivot is connected, and described moving block one end extends a driving lever.
As the further improvement of the technical program, the head of described driving lever is provided with a gib head.
Also as the further improvement of the technical program, described fixed pivot is located on the locating support.
The tight case hook device that adopts this technical scheme is by utilizing moving around of oil cylinder, and then controls the folding of tight case hook indirectly, when tight case hook is run into sandbox case hook, makes the further butt locking of case hook.This device can make the drag box face tight as far as possible, in order to avoid molten iron flows out.Efficiently solve drag box because the molten iron that lock does not tightly cause flows out problem, improved finished casting rate, and it is safer that the operative employee is operated, reliability has obvious improvement than higher with respect to prior art.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model being done one describes in detail.
Fig. 1 is a structural representation of the present utility model;
---support 11---connects pedestal 2---oil cylinder 21---piston rod among the figure: 1
3---moving block 31---fulcrum 32---driving lever 321---gib heads
The specific embodiment
Tight case hook device as shown in Figure 1 is provided with connection pedestal 11 at locating support 1 one ends, is fixed with an oil cylinder 2 to other end stretching, extension by connecting pedestal 11, and the front end of oil cylinder is a piston rod 21; The other end at locating support 1, location by fulcrum 31, moving block 3 hinges are connected in fulcrum 31 places, this fulcrum is roughly in the stage casing of moving block, the moving block profile roughly is two wing structures, one wing of its middle and upper part and the head hinge of piston rod 21 link together, serve as at piston rod under the effect of push rod, one wing of bottom roughly forms the structure of a driving lever 32, and also be provided with gib head 321 at the driving lever head, in fact the bottom wing of driving lever 32, gib head 321 and moving block has formed this device and has been used for the tight case hook of the application of force.
By the driving of oil cylinder, gib head partly is resisted against on the case hook of sandbox during use, can push up the locking position to the case hook of not locking.
