Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of quadric injection mould mould that can prevent the electric melting pipe fittings of the electric melting pipe fittings that resistance wire exposes for injection moulding.
The quadric injection mould mould of described a kind of electric melting pipe fittings, comprise respectively and injection machine upper plate, upper press plates and lower press plates that lower plate is fixing, fuse fixed head is set under upper press plates, under fuse fixed head, connect dynamic model fuse, on lower press plates, cover half fuse is set, upper press plates, on fuse fixed head and dynamic model fuse, correspondence position arranges sprue bush, it is characterized in that described be connected vertical with cover half fuse of dynamic model fuse, be used for installing pipe fitting, dynamic model fuse arranges with cover half fuse junction the runner communicating with sprue bush, the junction of dynamic model fuse and cover half fuse arranges quadric injection mould cavity with respect to the position of pipe fitting corner, on fuse fixed head, be provided for the retaining mechanism of fixed fitting.
The quadric injection mould mould of described a kind of electric melting pipe fittings, it is characterized in that described retaining mechanism comprises the oblique locking fuse being closely arranged on fuse fixed head, on fuse fixed head, mounting groove is set, oblique locking fuse one end is provided with spring, the one end that is provided with spring is positioned at mounting groove, and the other end stretches out fuse fixed head and pipe fitting touches.
The quadric injection mould mould of described a kind of electric melting pipe fittings, arranges buffer stopper on the termination, one end that the oblique locking fuse described in it is characterized in that and pipe fitting touch.
The quadric injection mould mould of above-mentioned a kind of electric melting pipe fittings, comprise respectively and injection machine upper plate, upper press plates and lower press plates that lower plate is fixing, fuse fixed head is set under upper press plates, under fuse fixed head, connect dynamic model fuse, on lower press plates, cover half fuse is set, upper press plates, on fuse fixed head and dynamic model fuse, correspondence position arranges sprue bush, dynamic model fuse is vertical with cover half fuse to be connected, be used for installing pipe fitting, dynamic model fuse arranges with cover half fuse junction the runner communicating with sprue bush, the junction of dynamic model fuse and cover half fuse arranges quadric injection mould cavity with respect to the position of pipe fitting corner, on fuse fixed head, be provided for the retaining mechanism of fixed fitting.The utility model, by adopting above-mentioned technology, carries out quadric injection mould by quadric injection mould cavity to the corner of pipe fitting, obtains the projection for wrapping up corner resistance wire, and the resistance wire that effectively solves pipe fitting exposes problem, thereby has avoided it to expose the impact bringing.
