Abstract
A pulling tool comprises a sleeve, a movable rod and a rotary knob. The head of the sleeve can be expanded to form a clamping claw. The movable rod can slide in the sleeve and expand the head of the sleeve, and the rotary knob makes the movable rod slide in the sleeve. One end of the movable rod is a wedge-shaped part which is used for expanding the head of the sleeve to form the clamping claw. The other end of the movable rod is a threaded rod part matched with the rotary knob. A rotation-stopping face is arranged on the outer side face of the middle of the movable rod and used for preventing the movable rod from rotating in the sleeve. The rotary knob is provided with a threaded hole matched with the threaded rod part. The sleeve is provided with an inner hole used for sliding of the movable rod, and a plane is arranged on the inner wall of the inner hole and matched with the rotation-stopping face of the movable rod. The pulling tool is novel in design and reasonable in structure, a straight insert caught in a die plate is very conveniently pulled out rapidly, moreover, a forming part of the insert can not be damaged, and the pulling tool has the advantages of being convenient to use rapidly and practical.
Description
Technical field
The utility model relates to a kind of pulling tool that the mold insert that is absorbed in the template is extracted fast be convenient to.
Background technology
In the complex-shaped surface mould of mould, exist some to adopt directly processing cutting comparatively projection or the darker shape of depression of difficulty, usually be designed to be commonly called as the mold insert into son, so both be beneficial to the machine-shaping of mould, be convenient to again the later mould that repairs a die, changes.There is a kind of straight body mold insert that is absorbed in the template in these mold inserts, for the forming part of protecting this mold insert is difficult for impairedly, often causes it to be difficult to from template, extract.
Summary of the invention
The purpose of this utility model provides a kind of pulling tool that the straight body mold insert that is absorbed in the template is extracted fast be convenient to.
For achieving the above object, technical solution adopted in the utility model is: a kind of pulling tool comprises sleeve that head can be strutted forms claw, can slide struts the knob that the motion bar of this sleeve head and the bar that innervates slide in sleeve in this sleeve; The other end is the threaded shank adaptive with knob to of motion bar in order to strut sleeve head to form the wedge-shaped part of claw, and the lateral surface at middle part is provided be used to the standstill face that prevents that motion bar from rotating in sleeve; Knob is provided with the screwed hole adaptive with the threaded shank of motion bar; Sleeve is provided with the endoporus that slides for motion bar, and the inwall of endoporus is provided with the plane adaptive with the standstill face of motion bar.
Using method of the present utility model is: the head of the utility model sleeve aperture by straight body mold insert is inserted into the inner, then turning knob, motion bar is slided in the endoporus of sleeve, thereby the wedge-shaped part that utilizes motion bar struts sleeve head to form claw, be buckled in the claw within the straight body mold insert, extract fast by mentioning the straight body mold insert that the utility model will be absorbed in the template; At last, the backward rotation knob, the wedge-shaped part of motion bar no longer struts sleeve head, so that sleeve head returns to the state of gathering, the utility model is taken out in mold insert.
Damage the claw of sleeve head in order to prevent that the sliding distance of motion bar in sleeve is excessive, the screwed hole place in knob is provided with latch.
Snap under the state tighter in the template at mold insert, in order to increase pulling capacity of the present utility model, below knob, be provided with portable plate, this portable plate is coated at sleeve, can utilize portable plate directly to increase pulling capacity, also can utilize portable plate bump knob to increase pulling capacity.
The utility model is novel in design, and rational in infrastructure, the very convenient straight body mold insert that will be absorbed in the template is extracted fast, and can not be damaged to the forming part of mold insert, has the characteristics of convenient practicality.
