Description

A kind of injection molding machine safety door

Technical field

The utility model relates to a kind of injection molding machine safety door.

Background technology

At present, the safety door that injector is used is the moving type security door, and pulley is installed on safety door, and safety door is placed on the lower railway of lathe bed by pulley.During use, pulley rolls along lower railway, and because safety door is heavier, the pulley rolling resistance is large, can produce sliding phenomenon, produces vibration and noise, makes safety door open mobile dumb, even stuck.Pulley is placed on the guide rail of lathe bed in addition, and pulley does not encase whole guide rail, belongs to for the semi open model setting, and the danger that causes safety door to have to break away from from guide rail, make the movement of safety door unstable.

The Chinese utility model that the existing patent No. is CN200720073612.9 discloses a kind of Portable security door rails for plastic jetting-moulding machine, comprise forward and backward moving door, upper plate, upper rail, lower guideway, be characterized in: upper rail consists of the square channel-section steel, and is fixed on template by the hanging feet that gets on the right track, and it is opening down; Lower guideway consists of square tube and pipe, and pipe is fixed in above square tube; Be equipped with the moving door bottom roller below forward and backward moving door, have arc groove on moving door bottom roller cylindrical, and roll and be connected with the pipe of lower guideway by arc groove, by connecting axle, rolling bearing is installed above forward and backward moving door, and rolling bearing stretches into, and the square channel-section steel is interior to roll and is connected with the square channel-section steel; Below upper plate, two sides are provided with the upper plate roller, and the upper plate roller rolls and is connected with square channel-section steel end face.This utility model has simple in structure, can make injection molding machine safety door move light, can solve injection molding machine safety door and open mobile inflexible technical problem.But the roller that this utility model adopts and guide rail are according to belonging to semi open model, and upper plate is easily recessed track.

The utility model content

The technical problems to be solved in the utility model is the present situation for prior art, provides a kind of movement laborsaving flexibly, reliable and stable injection molding machine safety door.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of injection molding machine safety door, rear safety door, the upper safety door that is arranged on described front safety door and rear safety door upper end that comprises front safety door, is oppositely arranged with described front safety door, be arranged on described upper safety door below upper rail, be arranged on the lower guideway of described front safety door and rear safety door bottom, described upper rail consists of the base plate that is arranged on the template top, the first guide plate and the second guide plate be arranged on this base plate; Described lower guideway consists of the shaft stool that is arranged on both sides, described template below, the axis of guide be arranged on this shaft stool; Be equipped with the linear bearing bearing that linear bearing is installed below described forward and backward safety door, described linear bearing rolls and coordinates with the described axis of guide; All be horizontally disposed with two spaced apart clutch shaft bearings and the second bearing above described forward and backward safety door, the first guide plate of described upper rail assigns between described clutch shaft bearing and the second bearing and is in contact with one another; Below described upper safety door, both sides are provided with and contacted the 3rd bearing of described the second guide plate, and below upper safety door, the 3rd bearing inboard is provided with the anticreep plate, on described anticreep plate, are provided with and contacted the 4th bearing of the base plate of described upper rail.

As improvement, described anticreep plate is the L-type steel plate, and it is positioned at the floor below of described upper rail.By be provided with L-type anticreep plate below upper safety door, retrained the possibility that safety door moves up, can effectively must prevent that derailment occurring from appearring in safety door.

Compared with prior art, owing to the utility model has the advantage of: by the rolling form of linear bearing is set at lower guideway, the rolling form of two bearings one guide plate is set at upper rail, guaranteed that moving door is rolling friction in upper and lower motion to guide rail on the one hand, make the movement of safety door laborsaving flexibly, retrained on the other hand all frees degree of safety door except the free degree moved along upper and lower guide rail, obtained safety door and move more reliable and more stable.
