Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, an in-mold flexible positioning mechanism for a cylindrical workpiece 200 is shown, for pushing the cylindrical workpiece 200 into a mold cavity of a mold 100, comprising: a guide base 1 having a guide hole 11 coaxial with the cavity; a push rod 2 inserted into the guide hole 11 to be linearly slidable coaxially with the guide hole 11; the ejector rod 3 can move relative to the push rod 2; and the elastic element 4 is arranged between the push rod 2 and the ejector rod 3, so that when the ejector rod 3 moves towards the push rod 2, the ejector rod 3 can push the push rod 2 through the elastic element 4, the push rod 2 pushes the columnar workpiece 200 arranged at the inlet of the die cavity into the die cavity, and when the columnar workpiece 200 abuts against the wall of the die cavity, the elastic element 4 can prevent the ejector rod 3 from rigidly abutting against the push rod 2 through self deformation.
With the above structure, when the push rod 3 is pushed by a driving source such as the cylinder 5 coupled to the push rod 3, the columnar workpiece 200 can be accurately pressed against the cavity wall, thereby ensuring the quality of the process molding, and the contractible flexible feature of the elastic element 4 can eliminate the redundant error caused by pushing the push rod 3, thereby preventing the columnar workpiece 200 and the cavity wall from being damaged by the push rod 3 being rigidly pressed against the push rod 2. Meanwhile, after the ejector rod 3 withdraws reversely, the elastic element 4 recovers to deform and can drive the push rod 2 to reset so as to prepare for next pushing operation. It will be appreciated that the length of the resilient element 4 when not fully compressed is such that the ram 3 can urge the ram 2 into abutment with the cylindrical workpiece 200 against the cavity wall.
In a preferred embodiment, the side of the push rod 2 facing the mold cavity may have a guide portion 21 with a gradually decreasing diameter (i.e. the diameter is reduced at other portions), and the guide portion 21 can guide the push rod 2 to slide accurately in the guide hole 11 when the push rod 2 reciprocates, so as to prevent the push rod 2 from rigidly colliding with or scraping against the guide seat 1.
In the present embodiment, the elastic element 4 is a spring. Of course, in other alternative embodiments, the elastic element 4 may also be an elastic pad or the like.
To further prevent the push rod 2 from damaging the cylindrical workpiece 200, the hardness of the push rod 2 may be less than that of the cylindrical workpiece 200.
The utility model discloses the principle and the implementation mode of the utility model are explained by applying the concrete embodiment, and the explanation of the above embodiment is only used for helping to understand the technical scheme and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
