Description
Technical field
The utility model relates to a kind of protective sliding door self-locking mechanism, is used for the self-locking of electric injection molding machine locked mode position protective sliding door, also can be widely used in the self-locking of miscellaneous equipment protective sliding door.
Background technology
Existing electric injection molding machine locked mode position folding mould is to use motor to control.When the locked mode machine operation, the action that the moving die plate at locked mode position does not just stop.At this moment, when this shift gate is opened,, can bring great hidden danger to the operator like this if the folding mould can also carry out; If the folding mould stops suddenly this moment, all very big damage can be arranged to locked mode motor and mechanical movement position, especially frequent startup and stopping.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of electric injection molding machine protective sliding door self-locking mechanism is provided, this mechanism had both guaranteed operator's personal safety, avoided again the locked mode motor stop suddenly the damage at the motor that brings and mechanical movement position.
The technical scheme in the invention for solving the above technical problem is: this electric injection molding machine protective sliding door self-locking mechanism, comprise electromagnet part and locking bed, locking bed is arranged on the protective sliding door, electromagnet partly is arranged on the fuselage, the corresponding coupling in electromagnet part and locking bed position, its characteristics are: described electromagnet partly comprises electromagnet, locking pin, bearing and spring, locking pin is arranged on the spindle nose of electromagnet, have centre bore on the bearing, pass through centre bore, bearing is sleeved on outside the locking pin and is fixed on the electromagnet, spring housing is contained on the locking pin, and between bearing and electromagnet spindle nose, have locking hole on the locking bed, the matched of locking hole and locking pin.
Locking bed described in the utility model is a U-shaped, and one side of U-shaped is fixed by screw and protective sliding door, and the another side of U-shaped is adjacent with the electromagnet part, has locking hole on this limit, locking hole shape and locking pin cross sectional shape coupling.
Have on the locking bed described in the utility model between the one side of locking hole and the bearing and be provided with the gap, the stroke coupling of this gap and electromagnet.
The utility model compared with prior art has the following advantages: the utility model adopts electromagnet to combine with spring, utilizes electromagnet after must be electric, produces bigger attraction and compresses spring, and locking pin is ejected, and locks firm protective sliding door.Spring reset when the electromagnet dead electricity withdraws from locking pin, the protective sliding door self-locking releasing.The utility model has guaranteed normally carrying out of safety in production, has improved the application life of machine, and especially the application life of motor is simultaneously simple in structure, and it is lower to make installation cost.
Description of drawings
Fig. 1 is the utility model released state schematic diagram.
Fig. 2 is the utility model locking state schematic diagram.
The specific embodiment
Referring to Fig. 1,2, the utility model comprises electromagnet part A and locking bed 6, and described electromagnet part A comprises electromagnet 2, locking pin 3, bearing 4 and spring 5.Locking bed 6 is arranged on the protective sliding door 7, electromagnet 2 is fixed on the fuselage 1, locking pin 3 is arranged on the spindle nose 21 of electromagnet 2, have centre bore 41 on the bearing 4, by centre bore 41, bearing 4 is sleeved on outside the locking pin 3 and is fixed on the electromagnet 2, spring 5 is sleeved on the locking pin 3, and between bearing 4 and electromagnet spindle nose 21, locking bed 6 is a U-shaped, one side of U-shaped is fixing with protective sliding door 7 by screw 62, be provided with clearance D between the another side of U-shaped and the electromagnet part A, the stroke coupling of this clearance D and electromagnet 2 has locking hole 61 on this limit, locking hole 61 shapes and locking pin 3 cross sectional shapes coupling, the matched of locking hole 61 height and locking pin 3.
During installation, at first locking pin 3 is contained on the spindle nose 21 of electromagnet 2, then spring 5 is contained on the locking pin 3, and with hand pressing spring 5 slightly, centre bore by bearing 4 41 packs into locking pin 3 centrally aligneds then, bearing 4 is fixed on the electromagnet 2 again, and activity is freely in bearing 4 to guarantee locking pin 3, then locking bed 6 is contained on the protective sliding door 7, determines that according to the position of the locking bed on the protective sliding door 76 the electromagnet part A is installed in the correct position on the fuselage 1 at last.After this position will guarantee that protective sliding door 7 shuts, when electromagnet 2 electric, the locking pin 3 compression springs on the electromagnet 2 eject, and eject the back and insert just in the locking hole 61 on the locking bed 6 on the protective sliding door 7.Protective sliding door 7 only depends on the operator to pull not open, have only when electromagnet 2 dead electricity like this, and spring 5 resets to free state, and locking pin 3 withdraws from locking bed 6, and protective sliding door 7 just can be opened.Electromagnet 2 the startup stop signal interlock of signal and locked mode motor of dead electricity, promptly when the locked mode electric motor starting, electromagnet 2 electric, compression spring 5, locking pin 3 push up 61 li of the locking holes of locking bed 6, protective sliding door 7 is locked firm, plays self-locking action.When the locked mode motor stops, electromagnet 2 dead electricity, spring 5 resets, and locking pin 3 withdraws from, protective sliding door 7 self-locking releasing.
In addition, need to prove, the specific embodiment described in this manual, titles that its each several part is named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
