Abstract

The utility model discloses a mounting structure of head board and guide pillar. It includes first board, the guide pillar, the nut, clamp plate and nut packing ring, four corners of first board are equipped with the boss, be equipped with the guide pillar hole on the boss, nut one end is equipped with the toper arch, the nut packing ring correspondence is equipped with the toper through-hole, the nut packing ring is arranged in on the guide pillar hole edge, the little one end of toper through-hole diameter is close to the boss, the toper arch of nut inserts in the toper through-hole, guide pillar hole and nut threaded connection are passed to guide pillar one end, the nut is extended to this tip, the clamp plate passes through screw connection with the boss, and the clamp. The utility model has the advantages of simple and reasonable structure, through the protruding cooperation atress of the toper through-hole of nut packing ring and nut, the great one end of nut packing ring terminal surface area offsets with the boss, and the head board guide post hole periphery enlarges with the area of contact of nut packing ring promptly, makes the head board pressure that receives diminish relatively, and under the unanimous condition of head board intensity, head board life is longer, and the counter bore reduces the guide post hole and the guide pillar assembly degree of difficulty.

Description

Mounting structure of head plate and guide pillar

Technical Field

The utility model relates to an injection molding machine technical field specifically relates to a mounting structure of first board and guide pillar for injection molding machine.

Background

The existing injection molding machine is shown in fig. 1, fig. 2 and fig. 5, including head plate 1, guide pillar 2, nut 5 and clamp plate, four corners of head plate 1 are equipped with boss 7, be equipped with guide pillar hole 10 on the boss 7, nut 5 front end is because of the atress reason, therefore 5 one end of nut is equipped with toper arch 50, guide pillar hole 10 corresponds and is equipped with the counter bore 12 of stepping down, toper arch 50 of nut 5 inserts the counter bore 12 of stepping down, and toper arch 50 and first counter bore contactless each other, make nut 5 and head plate 1 area of contact have lacked about 1/3, the area of stress reduces promptly, head plate 1 receives the pressure grow, and then so that head plate 1 guide pillar hole 10 peripheral structural strength reduces, and service life shortens.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can increase of service life's head board and guide pillar's mounting structure.

The purpose of the utility model is realized like this.

The utility model provides a first board and guide pillar's mounting structure, including first board, the guide pillar, nut and clamp plate, four corners of first board are equipped with the boss, be equipped with the guide pillar hole on the boss, still include the nut packing ring, nut one end is equipped with the toper arch, the correspondence of nut packing ring is equipped with the toper through-hole, the nut packing ring is arranged in on the guide pillar hole edge, the little one end of toper through-hole diameter is close to the boss, the toper arch of nut inserts in the toper through-hole, guide pillar hole and nut threaded connection are passed to guide pillar one end, this tip extends the nut, the clamp plate passes through screw connection with the.

The technical scheme can be further perfected as follows.

More specifically, a counter bore is formed at one end, close to the nut washer, of the guide pillar hole, and the diameter of the counter bore is smaller than the minimum diameter of the conical through hole.

The utility model has the advantages of simple and reasonable structure, through the protruding cooperation atress of the toper through-hole of nut packing ring and nut, the great one end of nut packing ring terminal surface area offsets with the boss, and the peripheral area of contact with the nut packing ring in head board guide post hole enlarges promptly, makes the head board pressure that receives diminish relatively, under the unanimous condition of head board intensity, the utility model discloses well head board life is longer, and the counter bore reduces guide post hole and the guide pillar assembly degree of difficulty.
