Abstract
The invention discloses a safety mechanism of a multi-station low-pressure casting machine. The safety mechanism comprises a lower bottom plate (1), a template (2), a safety pin telescopic cylinder (3), a safety pin (4) and guiding uprights (5), wherein the two guiding uprights (5) are arranged on the lower bottom plate (1), and slots are formed in the guiding uprights (5). The safety mechanism is characterized in that the guiding uprights (5) drive the template (2) to downwards move, the safety pin telescopic cylinder (3) pulls the safety pin (4), and the safety pin (4) is blocked on the slots of the guiding uprights (5) to ensure that the guiding uprights (5) and the template (2) move up and down together. The guiding uprights drive the template to automatically descend, and thus the potential safety hazard in an operating process is greatly reduced. The safety pin is prevented from being usually broken by the downward inertia of the guiding uprights and the gravity of the template because the cylinder cannot return in place, and the safety pin is only needed to be usually replaced.
Description
Technical field
The invention belongs to the metal casting machine technical field, relate to air injection machine, refer more particularly to the air injection machine of many kinds of work position.
Background technology
Low pressure casting is make liquid metals complete under pressure filling die cavity and process of setting and obtain a kind of casting method of foundry goods.For satisfying the auto parts and components lightweight, alloy wheel hub, engine cylinder-body, cylinder cap, gearbox body or other parts adopt Low Pressure Casting Technology production in a large number.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.Due to pressure used lower (20 ~ 60kPa), so be called low pressure casting.It is high that but the internal soundness of some foundry goods requires, hope crystallization under higher pressure, crystallization pressure is larger, the feeding effect is better, and the foundry goods that obtains is at last organized also finer and close, and the intensity of foundry goods and percentage elongation can increase substantially, but increase pressure by crystallization and improve casting quality, can not adopt in any case, structure and the electrical control part of the holding furnace of casting machine all proposed very high requirement, must take appropriate measures just to reach the purpose of high-pressure casting.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of multistation safety mechanism for low-pressure casting machine, to be provided with safety pin telescopic oil cylinder and safety pin in the guide upright post inboard, improve the production efficiency of air injection machine and the safety coefficient of equipment.
Technical scheme of the present invention is achieved in the following ways: the multistation safety mechanism for low-pressure casting machine, comprise lower shoe, template, safety pin telescopic oil cylinder, safety pin and guide upright post, lower shoe is provided with two guide upright posts, guide upright post is provided with draw-in groove, it is characterized in that: described guide upright post band moving platen moves downward, the safety pin telescopic oil cylinder pulls safety pin, and safety pin snaps into the draw-in groove on guide upright post, makes the motion together up and down of guide upright post and template.
Be connected with safety pin on described draw-in groove, safety pin is connected with the safety pin telescopic oil cylinder.
The present invention, guide upright post band moving platen toward descending, has reduced the potential safety hazard in operating process automatically greatly.The gravity that can not make the downward inertia of guide upright post and template because oil cylinder does not have to return the meeting of putting in place is often interrupted safety pin, only needs often to change safety pin and gets final product.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Known by Fig. 1, the multistation safety mechanism for low-pressure casting machine, comprise lower shoe 1, template 2, safety pin telescopic oil cylinder 3, safety pin 4 and guide upright post 5, lower shoe 1 is provided with two guide upright posts 5, guide upright post 5 is provided with draw-in groove, be connected with safety pin 4 on draw-in groove, safety pin 4 is connected with safety pin telescopic oil cylinder 3, described guide upright post 5 band moving platens 2 move downward, safety pin telescopic oil cylinder 3 pulls safety pin 4, safety pin can snap into the draw-in groove on guide upright post 5, the security that moves up and down to control guide upright post 5 and template 2.
