Abstract
The utility model relates to a steel oil-cylinder guide sleeve used for a die casting machine. The utility model is characterized in that the steel guide sleeve mainly consists of a guide sleeve body (5), wear-resisting rings (6), a step seal ring (2), a U-shaped seal ring (3) and a dustproof ring (4), wherein the wear-resisting rings (6), the step seal ring (2), the U-shaped seal ring (3) and the dustproof ring (4) are arranged in the guide sleeve body (5); the step seal ring (2) and the U-shaped seal ring (3) are arranged between the two wear-resisting rings (6); the dustproof ring (4) is positioned at the outlet end near the guide sleeve body (5) outside the wear-resisting rings (6); and the guide sleeve body (5) is made of steel. The guide sleeve has the advantages of low cost, high strength and small friction, therefore, the service life of the guide sleeve is improved.
Description
Technical field
The utility model relates to a kind of die casting machine, especially a kind of die casting machine oil jacket guide sleeve structure, specifically a kind of die casting machine steel oil cylinder guide pin bushing.
Background technique
As everyone knows, die casting machine mainly utilizes the hydraulic pressure moulding, has used various oil cylinders in die casting machine in a large number, as ejects oil cylinder, pressurizing cylinder, injection cylinder, lift cylinder etc.Piston rod in all kinds of oil cylinders must have guide sleeve to lead when operation, and existing oil cylinder guide sleeve all adopts tin bronze to make, it belongs to nonferrous materials, cost is higher, as shown in Figure 1, 2, it mainly is made up of tin bronze guide pin bushing body 1, this special seal ring 2, U type seal ring 3 and dust ring 4, because tin bronze guide pin bushing body 1 can rub with piston rod in the working procedure, the lead in the tin bronze can come off and enter the pollution that causes fluid in the hydraulic oil.
Summary of the invention
The purpose of this utility model is easy to wear and cause the problem of hydraulic oil pollution at existing tin bronze oil cylinder guide pin bushing, designs a kind of cost is low, frictional force is little die casting machine with steel oil cylinder guide pin bushing.
The technical solution of the utility model is:
A kind of die casting machine steel oil cylinder guide pin bushing, it is characterized in that it mainly is made up of guide pin bushing body 5 and the wear ring 6, this special seal ring 2, U type seal ring 3 and the dust ring 4 that are installed in the guide pin bushing body 5, described this special seal ring 2 and U type seal ring 3 are between two wear rings 6, and dust ring 4 is positioned at the outlet end place of wear ring 6 outsides near guide pin bushing 5; Described guide pin bushing body 5 is a steel guide pin bushing body.
Described steel guide pin bushing body is No. 45 steel guide pin bushings.
Described wear ring 6 is the anti-friction bearing band of loop configuration.
The beneficial effects of the utility model:
The utility model cost is low, the intensity height, and frictional force is little, helps improving the working life of guide pin bushing.
Description of drawings
Fig. 1 is the structural representation of existing oil cylinder and guide pin bushing thereof.
Fig. 2 is the local enlarged diagram of Fig. 1.
Fig. 3 is the structural representation of oil cylinder of the present utility model and guide pin bushing thereof.
Fig. 4 is the local structure for amplifying schematic representation of Fig. 3.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 3,4.
A kind of die casting machine steel oil cylinder guide pin bushing, it is installed in the entrance point place of oil cylinder, is used for the supporting piston bar and plays seal action simultaneously, as shown in Figure 3.This oil cylinder guide pin bushing mainly is made up of steel guide pin bushing body 5 and the wear ring 6, this special seal ring 2, U type seal ring 3 and the dust ring 4 that are installed in the steel guide pin bushing body 5, steel guide pin bushing body 5 can adopt common No. 45 steel or A3 steel to make, the quantity of described wear ring 6 is two supporting effects to play, can adopt common anti-friction bearing band manufacturing, described this special seal ring 2 and U type seal ring 3 are between two wear rings 6, and dust ring 4 is positioned at the outlet end place of wear ring 6 outsides near guide pin bushing 5.
The utility model does not relate to part to be realized as prior aries that maybe can adopt all same as the prior art such as guide pin bushing main body structure shapes.
Claims (3)
