Description

A kind of pin puller

Technical field

The utility model relates to the mold machining technology field, and specifically, it is a kind of instrument that can convenient, fastly extract pin.

Background technology

In the Mould Machining industry, various equipments machining dies need often to change mould template, need to often install and extract difform pin and change mould template.

Traditional method of extracting pin has two kinds, the one, load onto a sleeve pipe and carry out operation on the pin pin rod, the 2nd, tool using directly beats the mode of workpiece, above-mentioned dual mode all exists pin to take out the problems such as difficulty, effort, time length, and directly beat workpiece, can make die surface produce vestige, affect the overall appearance of mould.

Therefore, prior art awaits improving.

The utility model content

For the problems referred to above of the existence that exists in prior art, the purpose of this utility model be to provide a kind of can be convenient, fast, improve the service time of board and improve the pin puller of mold integral outward appearance.

For achieving the above object, the utility model is realized by following technological means: a kind of pin puller, comprise body, and described body is I shape, and described body is provided with the through hole suitable with the pin pin rod in axial direction.

Preferably, the outer circumference surface of described body is provided with annular groove, is circular in the middle of the shape of cross section of described annular groove, and two ends are nick circular arc.

Preferably, the cross section at the both ends of described body is regular hexagon.

Compared with prior art, the beneficial effects of the utility model are: by the design of said structure, in the time of need to extracting pin, operating personnel grasp the middle part of body and upwards exert oneself, carry out the pin pull action, not only convenient, fast, and reduced the time that pin is extracted, improve the service time of board, also improved the overall appearance of mould.

The utility model is simple in structure, and is reasonable in design, can extensively as the puller of difform pin, have practicality widely.

Description of drawings

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is the cross-sectional view of the utility model end;

Reference view when accompanying drawing 3 uses for the utility model.

In figure, each label is respectively: (1) body, (2) through hole, (3) annular groove, (4) end, (5) pin, (6) pad.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1 and Fig. 2, a kind of pin puller of the utility model comprises body 1,

Described body 1 is I shape, and described body is provided with the through hole 2 suitable with the pin pin rod in axial direction, conveniently the utility model is inserted on pin 5 pin rods; The outer circumference surface of described body 1 is provided with annular groove 3, is circular in the middle of the shape of cross section of described annular groove 3, and two ends are nick circular arc, and the handled easily personnel grasp the utility model, so that carry out pull action.

The cross section at the both ends 4 of described body 1 is regular hexagon.

The utility model can adopt iron or steel to make.

Through hole 2 shapes of the present utility model can be designed to according to the difformity of pin pin rod circle, square or other shapes, are complementary with the pin pin rod being suitable for.

During use, at first the utility model is inserted in the pin pin rod, then is inserted in a pad 6, then carry out hammering into of pin, realize fixing purpose; In the time of need to extracting, operating personnel grasp middle part of the present utility model, firmly upwards pin can be extracted.

In sum, the utility model designs by said structure, can extract various difform pins, have convenient, fast, improve board service time, improve the characteristics such as mold integral outward appearance.

The above, only better enforcement of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize above-mentioned technology contents to be changed or be modified to the equivalent embodiment of equivalent variations, at this, all the technical solution of the utility model contents that do not break away from, just foundation technical spirit of the present utility model to any simple modification, equivalent variations and modification that above embodiment does, all still belongs in the scope of technical solutions of the utility model.
