Abstract
The invention provides a pulling-out device which comprises a handle, a traction rod, a material pulling head, a heating rod and a guide sleeve. The heating rod comprises a heater for heating the material pulling head. One end of the traction rod is connected with the handle. The other end of the traction rod and one end of the heating rod are in coaxial rotational connection. The material pulling head is arranged at the other end of the heating rod, which is far away from the traction rod. An occlusion thread is arranged on the other side of the material pulling head, which is far away from the heating rod. A threaded through hole is formed in a heating jacket. The traction rod is arranged in the threaded through hole by threaded connection, and the material pulling head extends out of the heating jacket. The traction rod can be driven by the handle to rotate relative to the guide sleeve, thereby enabling the material pulling head to move in the extension direction of the threaded through hole.
Description
Technical field
The present invention relates to a kind of pulling attachment, particularly a kind of pulling attachment of the mould fracture that is used for choosing.
Background technology
Injection moulding machine commonly used work when start production just is often stable inadequately, so plastic product breaks in the phenomenon of master mold side when die sinking appears in regular meeting, must take out fracture and could continue to produce.Yet, also not being specifically designed to the instrument that takes out fracture in the mould in the prior art, the operating personnel generally can use sharp object in process of production, as: pocket knife or awl, fracture in the die cavity is ejected or scoop away, but this operational method is very lack of standardization, and mold damage easily.
Summary of the invention
Given this, be necessary to provide a kind of pulling attachment that can from mould, fracture be taken out easily.
A kind of pulling attachment, it comprises handle, drawing bar, pulls out stub bar, heating rod and fairlead.Described heating rod comprises that one is used to heat the described heater that pulls out stub bar.One end of described drawing bar links to each other with described handle.The other end of described drawing bar is connected with an end coaxial rotation of described heating rod.The described stub bar that pulls out is arranged on the other end of described heating rod away from drawing bar.The described stub bar that pulls out is provided with the interlock screw thread away from the opposite side of described heating rod.Offer a tapped through hole in the described heating jacket.Described drawing bar is screwed onto in the described tapped through hole, and the described stub bar that pulls out extend out to outside the described heating jacket.Thereby described drawing bar can be driven to rotate with respect to described fairlead the described stub bar that pulls out is moved along the bearing of trend of tapped through hole by described handle.
With respect to prior art, pulling attachment provided by the present invention merges so that described fracture is extracted by adding hot drawing stub bar and fracture, thus directly do not contact pulling out stub bar described in the process of fracture of choosing with mould, thus can not cause any damage to mould.
