Abstract

The utility model provides an injection molding machine high-efficiency soundless mechanical protector, which comprises a back connection receptacle, rollers, a flashboard, a bump wheel, an electromagnet and a mechanical lock lever. The ratchet wheel and pallet theory is adopted so that the opening and closing direction of the flashboard is in the same plane with the movement direction of the mechanical lock lever. Under such a circumstance, a rotor shaft is not only the axis of rotation but also the carrying shaft of the flashboard, and the rotor shaft does not receive the lateral pull force. When the protector plays a role in security protection, the flashboard is joggled with the mechanical lock lever under the action of the deadweight of the flashboard. The flashboard is primarily under pressure with small amount of deformation, is safer. The electromagnet just plays a role in reduction of vibration and abatement of noise throughout the overall working process of the protector. Even if the injection molding machine high-efficiency soundless mechanical protector fails electrically, the security protection function of the protector is not affected at all.

Description

Efficient noiseless Machine guarding

Affiliated technical field

The utility model relates to a kind of efficient noiseless Machine guarding of injection machine.

Background technology

Traditional injection machine Machine guarding, generally be to adopt two kinds of structures: first kind is that the mechanical lock flashboard is fixed on tailgate or the frame by flashboard axis, directly clashes into flashboard and flashboard by gate again and conducts oneself with dignity and control the keying of flashboard; Second kind is that the mechanical lock flashboard is fixed on tailgate or the frame by flashboard axis, controls the keying of flashboard earlier again by flexible axle by gate bump lance.

No matter traditional injection machine mechanical lock is first kind or second kind of structure, and the keying direction of flashboard is all vertical with the direction of motion of mechanical locking bar, does the time spent when mechanical lock plays safeguard protection, and flashboard mainly is subjected to shear action, deflects distortion seriously, and the protection effect is bad; Beating when semi-automatic in order to enhance productivity, often do not wait die sinking on earth even in goods coolings also not die sinking just open gate and wait for and get goods, flashboard falls with the frequent bump of mechanical locking bar flashboard is formed the power that side direction is pullled, because of the main design function of flashboard axis in traditional mechanical lock protective device is to use as rotating shaft, itself can not bear too big unbalanced load, and improvement can produce unreasonable structure and influences outward appearance again on former design basis; Flashboard axis be subjected to frequently outwards pullling shake easily pine in addition fracture and noise excessive, seriously reduce original security performance of mechanical lock and environmental requirement.

Summary of the invention

Technical problem to be solved in the utility model: a kind of injection machine Machine guarding is provided, and this device makes it reach the requirement of efficient and noise reduction by the design that changes frame for movement.

The utility model solves the technical scheme that its technical problem adopts: a kind of Machine guarding of injection machine, it comprises the back Connection Block, rotating shaft, roller, roller packing ring, flashboard packing ring, connecting plate, little pressing plate, pressing plate, flashboard, hits the wheel installing plate, hits wheel shaft, hits wheel, hits and take turns packing ring, electromagnet baffle plate, electromagnet fixed head, electromagnet, mechanical locking bar, locking bar rotating shaft, locking bar packing ring; Back Connection Block, rotating shaft, roller, wheel roll packing ring, flashboard packing ring, connecting plate, little pressing plate and pressing plate assembling back shape supporting targeting part; Flashboard, hit the wheel installing plate, hit wheel shaft, hit wheel, hit wheel packing ring, electromagnet baffle plate, electromagnet installing plate and electromagnet assembling back form and control operating part; Machinery locking bar, locking bar rotating shaft and locking bar packing ring assembling back form the matched moulds double-action part.

The beneficial effects of the utility model:

1. the device of utility model adopts the click principle, the keying direction that makes flashboard and the direction of motion of mechanical locking bar on same plane, rotating shaft at this moment be the rotating shaft of flashboard be again reach, and the power that side direction is pullled is no longer born in rotating shaft; When playing safeguard protection, this device does the time spent, the rapid and mechanical locking bar engagement of the flashboard assembly of this design energy under deadweight, and protective reaction is fast; Because of the main pressurized of flashboard, deflection is little again, and security performance is higher.

The device of utility model by computer program with electromagnet and locked mode reversal valve and the binding of locked mode terminating switch, normal conditions electromagnet when the locked mode final state gets, electromagnet core stretches out and stops flashboard to fall, thereby avoid the frequent bump of flashboard and locking bar when opening the situation lower open die of gate and produce noise, up to any next time locked mode when action electromagnet dead electricity arranged, electromagnet makes electromagnet core withdraw because of back-moving spring is housed, but flashboard free-falling this moment; In order to protect the service life of electromagnet, do not allow single oversize conduction time in addition, thus when the electromagnet single get the electric time when surpassing setting value the automatic dead electricity of electromagnet wait for next action.

3. electromagnet only works to reduce vibration and abates the noise in the entire work process of the utility model device, even the safeguard protection effect that does not also influence this device fully out of joint of electric aspect.
