Description

technical field [0001] The invention relates to a machine for processing plastic electrofusion pipe fittings, in particular to a core pulling machine for plastic electrofusion pipe fittings. Background technique [0002] After plastic electrofusion pipe fittings are injection molded, due to their large tightness and resistance wires wound on the inner wall of the pipe fittings, the core and electrofusion pipe fittings must be taken out of the mold for cooling first, and then the core and electrofusion pipe fittings Put it on the core-pulling machine for core-pulling, which is beneficial to the core-pulling of electrofusion pipe fittings and guarantees product quality. Existing core-pulling machines for electrofusion pipe fittings, such as Chinese Patent No. ZL201220210318.9, the patent name is "a platform-type electrofusion pipe fitting core-pulling machine". The core-pulling mechanism of the patented core-pulling machine includes a frame, a platform desktop, The drive mech...

Existing core-pulling machines for electrofusion pipe fittings, such as Chinese Patent No. ZL201220210318.9, the patent name is "a platform-type electrofusion pipe fitting core-pulling machine". The core-pulling mechanism of the patented core-pulling machine includes a frame, a platform desktop, The drive mechanism used to drive the core and the drive mechanism mounting plate used to install the drive mechanism, guide posts are installed on the drive mechanism mounting plate, lifting clamps are installed on the guide posts, and there are 2 or more than 2 on the table top of the platform The disadvantage of this structure is that after the driving mechanism drives the lifting pallet to pull the core on one end of the electrofusion pipe fitting, it is necessary to manually rotate the electrofusion pipe fitting to make the core on the other end After being fixed with the lifting pallet, the core is pulled out. After the core is pulled out, the electrofusion pipe is manually taken out. The operation is cumbersome. Even if the robot is used to rotate or pick up the parts, the structure of the robot is complicated and the manufacturing cost is high. In addition, when pulling the core, There is no protective device on the platform desktop, and there are certain potential safety hazards
