Abstract
The invention relates to a safety mechanism for a low pressure die casting machine, and the safety mechanism comprises a lower bed plate (1), a mould plate (2) and four guide uprights (3) respectively connected with a cylinder, wherein the cylinders drive the guide uprights (3) and the mould plate (2) to move up and down along a rail, each guide upright (2) is internally provided with a safety pull shaft (5). The safety mechanism provided by the invention is characterized in that the safety mechanism is wrapped on each safety pull shaft (5). A tightening sleeve of the safety mechanism provided by the invention always wraps the safety pull shaft, the problem that a pull crack is produced or the mould plate is dropped to cause a fault as stress on each guide upright is not even and oil pressure in each cylinder is not even in an operation process can be avoided, and the potential safety hazard in the operation process is greatly reduced.
Description
Technical field
The invention belongs to and belong to the metal casting machine technical field, refer more particularly to the air injection machine release mechanism of multiple station.
Background technology
Along with the fast development of Domestic Automotive Industry,, adopt the low pressure casting technology to produce in a large number to alloy wheel hub, engine cylinder-body, cylinder cap, gearbox body or other parts for satisfying the auto parts and components lightweight.In other field, as aviation, textile machinery etc., also all gradually adopting low pressure casting spare, to improve the quality of products, reduce machining, alleviate weight of equipment.Existing air injection machine, according to devices such as the limit mould oil cylinder of equipment fixed position and fixed qty and release mechanisms, general being fit to, be not easy to according to diversified various foundry goods controlling and the not high defective of safety coefficient when the conversion station is produced or cast accordingly according to fixing station casting.
Summary of the invention
At the deficiency of above-mentioned air injection machine, the object of the present invention is to provide the air injection machine release mechanism of one kind of multiple stations, be to be provided with safe pulling shaft in guide upright post, the security that moves up and down with control guide upright post and template.
Technical scheme of the present invention realizes in the following manner: the air injection machine release mechanism, comprise that lower platen, template, four guide upright posts are connected with oil cylinder respectively, oil cylinder drives guide upright post and template moves up and down along track, be provided with safe pulling shaft in the guide upright post, it is characterized in that: packed tightly release mechanism on the described safe pulling shaft.
Described release mechanism is by stretching cover, rectangle spring, and induction rod is formed, and packs tightly a stretching cover on the safe pulling shaft, and rectangle spring, induction rod are stuck in stretching and put, and control safe pulling shaft and move up and down.
Structure of the present invention, the stretching of release mechanism cover is packing tightly safe pulling shaft all the time, can be because of in operating process, and in-oil cylinder oil pressure is inhomogeneous and make the guide upright post discontinuity produce drawing crack, cause template to come off and cause fault, greatly reduce the potential safety hazard in the operating process.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the release mechanism schematic diagram.
Fig. 3 is the prior art constructions schematic diagram.
The specific embodiment
Know by Fig. 1, the air injection machine release mechanism of present embodiment comprises that lower platen 1, template 2, four guide upright posts 3 are connected with oil cylinder respectively, and oil cylinder drives guide upright post 3 and template 2 and moves up and down along track, be provided with safe pulling shaft 5 in the guide upright post 3, be provided with release mechanism in the guide upright post 3.
Being known by Fig. 2, is the release mechanism schematic diagram.By stretching cover 7, rectangle spring 6, induction rod 4 is formed, and packs tightly stretching cover 7 on the safe pulling shaft 5, and rectangle spring 6, induction rod 4 are stuck on the stretching cover 7, control safe pulling shaft 5 and move up and down.
Fig. 3 is a prior art air injection machine release mechanism schematic diagram.Existing air injection machine release mechanism: when four oil cylinders connect the piston motion, can be because inhomogeneous safe pulling shaft tendency and the big one side of pressure of making of the pressure of oil cylinder size, and the safe pulling shaft that has earlier is a height of adjusting pulling shaft by the sawtooth on the pulling shaft, this release mechanism exists very big potential safety hazard, and has reduced greatly the service life of equipment.In the time of safety pin telescopic oil cylinder 9 pulling safety pin 8, safety pin 8 can snap into the draw-in groove on the guide upright post 3, put in place can be because the downward inertia of guide upright post and the gravity of template if this release mechanism oil cylinder does not have to return, safety pin 8 is often interrupted, so just need often to change safety pin, if in time do not change safety pin, safety pin 8 just may rupture, and safety pin 8 can just not aim at draw-in groove at every turn yet, exists very big potential safety hazard.
Claims (2)
