Description
Technical Field
The utility model relates to a pull rod lubricating oil seal structure, especially a seal structure of injection molding machine pull rod lubricating oil.
Background
During the working period of the injection molding machine, the pull rod and the template guide sleeve are in a relative motion state, dry friction is not possible in the state, lubricating grease must be added, and the lubricating grease causes the problem of grease flowing, so that the die mounting surface and the die are polluted in the working process of the injection molding machine.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a seal structure of injection molding machine pull rod lubricating oil in order to overcome prior art not enough.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a seal structure of injection molding machine pull rod lubricating oil which characterized in that: including pull rod, bush, sealing washer, gland and template, there is the bush through the lubricating oil sliding connection on the face of cylinder pull rod's the face of cylinder, and the bush rigid coupling is on the inner wall of template, and the cover is equipped with the sealing washer on the pull rod, and the sealing washer is convex style of calligraphy for cyclic annular structure and side, and the gland crimping is on the chimb recess of sealing washer, and the gland passes through the fix with screw in the terminal surface recess of template, encloses between the chimb of sealing washer and the pull rod and establishes into lubricating oil storage space.
Preferably, the sealing rings are symmetrically arranged at two ends of each pull rod.
Preferably, each injection molding machine is provided with 4 sealing structures of the pull rod lubricating oil.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
injection molding machine pull rod lubricating oil's seal structure avoids lubricating oil trickling to mould installation face and mould on and pollute mould installation face and mould.
Drawings
FIG. 1 is a schematic view of a sealing structure of the injection molding machine pull rod lubricating oil of the present invention;
figure 2 is the utility model discloses a local enlarger of seal structure of injection molding machine pull rod lubricating oil.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In the attached drawings 1-2, a sealing structure of injection molding machine pull rod lubricating oil comprises pull rods 10, bushings 30, sealing rings 20, a gland 25 and a template 40, wherein the cylindrical surfaces of the cylindrical pull rods 10 are slidably connected with the bushings 30 through the lubricating oil, the bushings 30 are fixedly connected to the inner wall 45 of the template 40, the pull rods 10 are sleeved with the sealing rings 20, the sealing rings 20 are of annular structures, the side surfaces of the sealing rings are in a convex shape, and the sealing rings 20 are symmetrically arranged at two ends of each pull rod 10; the gland 25 is pressed on the groove of the convex edge 21 of the sealing ring 20, the gland 25 is fixed in the end surface groove of the template 40 through screws, and a lubricating oil storage space is enclosed between the convex edge 21 of the sealing ring 20 and the pull rod 10. Each injection molding machine is provided with a sealing structure of 4 pull rod lubricating oils.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
