Description
Technical field
The utility model relates to injection-blow molding machine technical field, refers to that especially a kind of note blows the plug in blow moulding machine.
Background technology
Plastic shaping mechanism is molded as follows by basic functional principle: first form parison, after use compressed air (with stretching bar) to carry out radially inflation (with axial tension) parison, make it to be adjacent to (stretching) blow mold die cavity, the shape of die cavity and size, give goods, and cooling it.
According to the method for parison formation, blow molding is divided into extrusion and blow molding and the large class of injection-blow molding moulding two; The equipment of extrusion and blow molding (especially mould) cost and energy consumption are lower, plastic large-volume receptacle and complex-shaped goods; The container of injection-blow molding moulding, has higher dimensional accuracy, does not form joint close, does not generally produce leftover pieces.
Current common note blows blow moulding machine and generally adopts the fit clearance between mandrel body and core head to complete the air blowing to pipe embryo, and plug inside only has an air blowing pipeline.Plug inside does not have temperature control, and long time running plug temperature can not get controlling, and directly affects the uniformity of product molding.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of note simple in structure, lower-cost to blow the plug in blow moulding machine, can solve the problem of plug head temperature control.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of note blows the plug in blow moulding machine, comprise mandrel body, be movably arranged on the mandrel body mold insert and the core head that is movably arranged on mandrel body end of first half in mandrel body, core head front end stretches in mandrel body, and this end is stretched in mandrel body mold insert, this end is arranged with spring, spring one end and mandrel body inwall are inconsistent, the other end and mandrel body mold insert outer wall are inconsistent, on described mandrel body, be provided with cooling liquid inlet and cooling liquid outlet, in mandrel body mold insert, be provided with cooling water pipe, cooling water pipe comprises water pipe internal layer and water pipe skin, water pipe internal layer is connected with cooling liquid inlet, water pipe is outer to be connected with cooling liquid outlet, the first half section of cooling water pipe is arranged in mandrel body mold insert, its second half section is arranged in core head, and be connected with water pipe skin at this section of end water pipe internal layer, on mandrel body, be provided with air inlet and gas outlet, gas outlet is arranged on the position that mandrel body end contacts with core head, and be connected with mandrel body inside, air inlet is arranged on the front end of mandrel body, in mandrel body mold insert, be provided with tracheae, tracheae end is connected with mandrel body inside, its front end is connected with air inlet.
Described mandrel body front end is provided with aperture, and mandrel body mold insert front end is provided with protuberance, and protuberance is movably arranged in aperture and with aperture and matches.
The beneficial effects of the utility model are: the plug that above-mentioned a kind of note blows in blow moulding machine has adopted two circuit design, make gas circuit and oil circuit separately, and two loops are non-interference, and solved the temperature control problem of plug head, and simple and practical, cost is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation that note described in the utility model blows the plug in blow moulding machine.
