Description
Technical field
The utility model belongs to the injection machine technical field, relates to a kind of injection machine machine insurance mechanism.
Background technology
In order to guarantee to use the security of injection machine, all be provided with safety door on the injection machine, after opening behind the safety door, need injection machine can not carry out mould assembling action and realize stoppage protection; So needing increases the machine insurance structure, to avoid danger, and existing injection machine machine insurance mechanism mainly is utilized in after safety door is closed installs blind rivet on the guide rail; Utilize the boss of blind rivet to block trolley, thereby realize machine insurance, the shortcoming of this structure is that blind rivet meeting easy to wear was lost efficacy; And for example the disclosed a kind of injection machine safety door of Chinese patent document [notification number: CN201506021] is prevented unloading device; Comprise hexagonal socket head cap screw, spring, the first anti-back main body and the second anti-back main body,, make the anti-back bar of the first anti-back main body and second anti-back main body chucking trolley axle mainly through the effect of spring; Thereby realization machine insurance; Can find out the just simple active force realization machine insurance that relies on spring of this structure, along with long use, flexible elastic force can weaken; So just do not have the effect of machine insurance, can not effectively guarantee injection machine operating personnel's personal safety.
Summary of the invention
The utility model technical problem to be solved is the present situation to prior art, and provides a kind of security performance good, the injection machine machine insurance mechanism that can effectively avoid the personal injury phenomenon to take place.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of injection machine machine insurance mechanism; It is characterized in that; Comprise the machine insurance bar that is fixedly connected with the injection machine removable wall, slide bar and machine insurance pivoted lever are respectively arranged with front limit piece and back limited block on injection machine; Described machine insurance pivoted lever is located between front limit piece and the back limited block; Described slide bar and the parallel connection of machine insurance pivoted lever are fixed with gate insurance pulley on the machine insurance pivoted lever, on slide bar, be fixed with the machine insurance block that matches with the machine insurance bar.
Here when safety door was opened, safety door cooperated with gate insurance pulley, makes the machine insurance pivoted lever inwardly rotate; Because slide bar and the parallel connection of machine insurance pivoted lever drive slide bar so again and inwardly rotate, make the machine insurance block be stuck in and just limited the transverse movement of machine insurance bar on the machine insurance bar again; Injection machine just can not matched moulds like this, thereby realizes machine insurance, when safety door is opened; Safety door withdraws from from gate insurance pulley, drives slide bar when the machine insurance pivoted lever outwards rotates so again and outwards rotates, and makes the machine insurance block withdraw from from mechanical bumper bar; The machine insurance bar again can free transverse movement, realizes injection machine work.
The measure of taking for the optimization such scheme specifically comprises:
In above-mentioned a kind of injection machine machine insurance mechanism; Be respectively arranged with the first machine insurance connecting rod and the second machine insurance connecting rod between described slide bar and the machine insurance pivoted lever, described slide bar is through the first machine insurance connecting rod and the second machine insurance connecting rod and the parallel connection of machine insurance pivoted lever.Here connect through the first machine insurance connecting rod and the second machine insurance connecting rod, be stability, thereby insure effectively in order to guarantee that machine insurance pivoted lever drive slide bar rotates.
In above-mentioned a kind of injection machine machine insurance mechanism; The other locating ring that is provided with of the described first machine insurance connecting rod; Described locating ring is enclosed within on the machine insurance pivoted lever; Between locating ring and front limit piece, be provided with the back-moving spring that is set on the machine insurance bar, an end of described back-moving spring withstands on the locating ring, and the other end withstands on the front limit piece.Here the effect for locating ring mainly is that back-moving spring is installed for ease; The effect of back-moving spring is to make the machine insurance pivoted lever after rotation, have certain tensioner screen resilience, thus guarantee on the slide bar the machine insurance block inflexibly block the machine insurance bar.
In above-mentioned a kind of injection machine machine insurance mechanism, be provided with the ratchet of indentation on the described machine insurance bar at regular intervals, described machine insurance block is stuck on the ratchet.Here can be advantageously that the machine insurance lever lock is dead through ratchet, make injection machine can not carry out mould assembling action and realize stoppage protection, can effectively avoid the personal injury phenomenon to take place.
In above-mentioned a kind of injection machine machine insurance mechanism; Fixed block and back fixed block before the injection machine removable wall is provided with; Between fixed block and the back fixed block, described back fixed block and machine insurance bar were provided with the bumper bar briquetting before described machine insurance bar was located in.Here the effect of bumper bar briquetting is a limit mechanical bumper bar transverse movement direction, and prevents that the machine insurance bar from rotating, thereby influences the injection machine matched moulds.
In above-mentioned a kind of injection machine machine insurance mechanism, the rear end of described machine insurance bar also is provided with pieces together tight screw, and the rear end of machine insurance bar is locked on the fixed block of back through piecing together tight screw, and the machine insurance block is stuck in the front end of machine insurance bar.
Compared with prior art; The advantage of the utility model is that security is good, through the ratchet of the stuck machine insurance bar of machine insurance block, has just limited the transverse movement of machine insurance bar; Make injection machine can not carry out mould assembling action and realize stoppage protection, can effectively avoid the personal injury phenomenon to take place.
