Description

Quick demoulding structure of injection molding shell Technical Field The utility model relates to the technical field of injection molds, in particular to a rapid demolding structure of an injection molding shell. Background In the injection molding field, the production of injection molding shell is very common technological process, traditional injection mold is after the completion of moulding plastics, need deviate from fashioned shell from the mould die cavity, but current drawing of patterns mode is ejecting the shell of shaping through the thimble, and the thimble is thinner, when the shell is ejected, the thimble head stress concentration, causes the damage condition such as crack, deformation to the shell easily, simultaneously at the in-process of moulding plastics, the quantity of raw and other materials can not be accurately controlled in artifical injection molding, unnecessary part can be extruded by the mould when the feeding, cause the flash extravagant, in order to solve above-mentioned problem, consequently, need the quick demoulding structure of injection molding shell. The problem that the existing injection molding shell demolding structure cannot be quickly demolded and cannot quantitatively feed is solved when the existing injection molding shell demolding structure is operated, and the injection molding shell quick demolding structure is urgently needed. Disclosure of utility model Based on the above, the utility model aims to provide a rapid demoulding structure of an injection molding shell, so as to solve the problems that the existing injection molding shell demoulding structure cannot be rapidly demoulded and cannot be quantitatively fed when in use. In order to achieve the above purpose, the utility model provides the technical scheme that the quick demoulding structure of the injection molding shell comprises a base, wherein a mould is arranged on the inner wall of the base, an extrusion block is arranged on the outer wall of the mould, a positioning rod is arranged at the bottom of the mould, a reset rod is arranged on the side wall of the extrusion block, an extrusion spring is arranged on the outer wall of the reset rod, a support is arranged at the top of the base, an electric cylinder is arranged at the top of the support, a limit rod is arranged on the inner wall of the support, a pressure head is arranged at the bottom of the limit rod, a fixing frame is arranged on the side wall of the base, a bin is arranged on the inner wall of the fixing frame, a transmission motor is arranged at the top of the bin, and a blanking rod is arranged at the bottom of the transmission motor.
