Specific embodiment

The core of the utility model is to provide a kind of band andgudgeon of cold-chamber die casting machine, and the service life of the band andgudgeon extends.

It is with reference to the accompanying drawing and real in order to make those skilled in the art more fully understand the technical solution of the utility model Applying mode, the utility model is described in further detail.

Fig. 1 to Fig. 5 is please referred to, in a specific embodiment, cold house's pressure that the utility model specific embodiment provides The band andgudgeon of casting machine includes the first dowel 4 that fuselage 2, point hinge 5, assembly bench 7 and both ends are connect with fuselage 2 and point hinge 5 respectively, the One dowel 4 is triangle member structure, and fuselage 2 is equipped with assembly bench 7 with a point both ends for hinge 5.In order to reduce band andgudgeon difficult processing Degree, it is preferable that the first dowel 4 is positive triangle member structure.

As can be seen from the above description, in the band andgudgeon provided by the application specific embodiment, since the first dowel 4 is three Angular member structure, due to two of triangle rod piece while not common endpoint with Article 3 while connect because third side can not Flexible or bending, so two-end-point distance is fixed, and then two-end-point distance is fixed, and then the angle on this two sides is fixed at this time, It is taken because two sides are appointed, three angles all secure, and triangle stability is higher, and then avoid frequently pulling band andgudgeon When, the first dowel 4 comparatively fast generates deformation, leads to the case where fuselage 2 is with dividing 5 relative positions of hinge to generate deformation, therefore, this Shen The service life for the band andgudgeon that please be provided extends.The case where frequently replacing band andgudgeon is avoided simultaneously, is improved work efficiency.
