Abstract
The invention provides an injection molding machine crosshead slide block. The crosshead slide block at least comprises: two crosshead guide pillar holes, a plurality of oil-containing bearing bushes arranged on inner wall surfaces of the crosshead guide pillar holes, and dust caps arranged on side wall surfaces of the crosshead guide pillar holes. A plurality of stepped holes are symmetrically arranged on the dust caps. Fasteners extend into the stepped holes, and are threadedly connected with blind holes with inner threads arranged on the side wall surfaces, such that the dust caps are fixedly held on the side walls. A ring of receiving recess is provided in each dust cap, and a dustband is embedded in each receiving recess. With the structure, when the crosshead slide block and the crosshead guide pillars perform relative movements, the crosshead guide pillars are prevented from being damaged by the impurities attached to the surfaces of the crosshead guide pillars. Therefore, the service life of the crosshead guide pillars is prolonged, and the sliding smoothness of the crosshead slide block and the crosshead guide pillars is improved.

The specific embodiment
Below in conjunction with each embodiment shown in the drawings the present invention is elaborated; But should be noted that; These embodiments are not limitation of the present invention; The function that those of ordinary skills do according to these embodiments, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Please join shown in Figure 1ly, Fig. 1 is the explosive view in crosshad shoe one specific embodiment of a kind of injection machine of the present invention.In this embodiment, this crosshad shoe 100 comprises at least: two crosshead guide pillar holes 10, and be arranged on the some oilite bushings 20 on the internal face 101 in said crosshead guide pillar hole 10.And be arranged at the dust cap 40 on the side wall surface 102 in crosshead guide pillar hole 10, it is symmetrical set four shoulder holes 404, extends into shoulder hole 404 through securing member 50, and with this side wall surface 102 on blind hole 103 bolts of the tool internal thread that is provided with.In order to said dust cap 40 is immobilizated on the side wall surface 102.In this embodiment, these dust cap 40 inside are provided with a circle and accommodate groove 403, and said accommodating is embedded a dust ring 30 in the groove 403.
In conjunction with shown in Figure 2; In this embodiment; The internal face 101 in this crosshead guide pillar hole 10 is provided with two oilite bushings 20; And these two oilite bushings, 20 mutual discontinuous contacts can reduce crosshead guide pillar 200 like this and do in the relative motion process with crosshad shoe 100, reduce the frictional resistance between crosshead guide pillar 200 and the crosshad shoe 100.
In conjunction with Fig. 3 and shown in Figure 4, in this embodiment, this crosshad shoe 100 is provided with two crosshead guide pillar holes 10, is equipped with a dust cap 40 on the side walls face 102 in each crosshead guide pillar hole 10.And be provided with four tool internal threads and symmetrically arranged blind hole 103 on the surface of side wall surface 102.
Can use securing member 50 like this, extend in the shoulder hole 404 of this dust cap, and with this side wall surface 102 on four tool internal threads and symmetrically arranged blind hole 103 bolts.Thereby whole dust cap 40 is immobilizated on the side wall surface 102 reliably.In this embodiment, this securing member 50 can be screw, also can be rivet.
Join shown in Figure 5ly, in this embodiment, this dust cap 40 is provided with first through hole 401 and second through hole 402, and this first through hole 401 and second through hole 402 are arranged at the both sides that this accommodates groove 403 respectively.And the diameter of this first through hole 401 is greater than the diameter of said second through hole 402.The external diameter of this dust ring 30 equates with the internal diameter of accommodating groove 403.The internal diameter of this dust ring 30 equals the diameter of this second through hole 402.Simultaneously, the diameter of this second through hole 402 is greater than the diameter of this crosshead guide pillar 200.Through this structure, can guarantee that dust ring 30 does not all contact with crosshead guide pillar 200 with the thinner wall section 42 at second through hole, 402 places.
Because this dust ring 30 has certain elasticity, can distorted shape passing this first through hole 401, and at the diameter of second through hole 402 less than first through hole 401, accommodated so dust ring 30 can accommodate groove 403 reliably.
The listed a series of detailed description of preceding text only is specifying to feasibility embodiment of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
