Abstract
A threaded rod is arranged at the front part of a connecting rod, an annular groove for installing a clamping sleeve is arranged at the rear part of the threaded rod on the connecting rod, a boss is arranged at the rear part of the groove, a downward-sunken cambered surface structure is arranged in the groove, and the diameter of the downward-sunken cambered surface in the groove is 2-3mm smaller than the inner diameter of the thread. The utility model discloses a mould connecting rod structure, the connecting rod recess shape change of equipment cutting ferrule, the recess outside is the cambered surface by straight face change, on the tensile force that bears the screw thread department shifts half to the recess, makes connecting rod screw thread department not break to production efficiency has been improved.
Description
Technical Field
The utility model relates to a casting mould technical field.
Background
The connecting rod structure of the traditional casting mould is shown in figure 1, a threaded rod 1 is arranged at the front part and is used for being connected to a mould frame or an oil hydraulic cylinder, a groove 2 is a joint of a clamping sleeve and the connecting rod, a boss 3 is arranged at the rear part of the groove 2, the two connecting rods are connected and fixed through the clamping sleeve, and the boss 3 is used for fixing the position of the connecting rod by the clamping sleeve; the mould is often damaged at the threaded rod 1 of the connecting rod during the casting process, resulting in low daily output of the casting machine. When the connecting rod is broken, the die of the gold-shaped part needs to be repaired, which wastes time and labor, and the casting machine has long stop time and affects the yield.
Disclosure of Invention
In order to solve the problem that the casting mould connecting rod rolls over the damage easily, the utility model provides a mould connecting rod structure.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a mould connecting rod structure, the connecting rod front portion is the threaded rod, lies in the threaded rod on the connecting rod rear portion and is equipped with the annular groove of installation cutting ferrule, and the recess rear portion is the boss, the inside cambered surface structure of undercut of recess.
The diameter of the cambered surface sunken downwards in the groove is 2-3mm smaller than the inner diameter of the thread.
The utility model discloses a mould connecting rod structure, the connecting rod recess shape change of equipment cutting ferrule, the recess outside is the cambered surface by straight face change, on the tensile force that bears the screw thread department shifts half to the recess, makes connecting rod screw thread department not break to production efficiency has been improved.
Drawings
Fig. 1 is a structural view of a conventional mold connecting rod.
Fig. 2 is the structure diagram of the mold connecting rod of the present invention.
In the figure: 1. threaded rod, 2, straight face recess, 3, boss, 4, recess.
Detailed Description
The utility model discloses a mould connecting rod structure is shown in fig. 2, and the connecting rod front portion is threaded rod 1, lies in threaded rod 1 rear portion on the connecting rod and is equipped with the annular groove of installation cutting ferrule, and 4 rear portions of recess are boss 3, the inside undercut's of recess 4 cambered surface structure, and the inside undercut's of recess 4 cambered surface diameter is for being less than the minor diameter of screw thread 2-3 mm.
The position that the connecting rod broke is always in screw thread department, in order to make screw thread department not break and damage, change connecting rod recess 4 (equipment cutting ferrule position) shape, the recess 4 outside is the cambered surface by the change of straight face, shifts half the tensile force that the screw thread department bore to the recess (the position of equipment cutting ferrule), makes connecting rod screw thread department not break and damage.
Claims (2)
1. The utility model provides a mould connecting rod structure which characterized in that: the connecting rod front portion is threaded rod (1), lies in on the connecting rod threaded rod (1) rear portion and is equipped with annular groove (4) of installation cutting ferrule, and recess (4) rear portion is boss (3), the inside cambered surface structure of undercut of recess (4).
2. The die connecting rod structure according to claim 1, wherein: the diameter of the cambered surface sunken downwards in the groove (4) is 2-3mm smaller than the inner diameter of the thread.
