The work process of mould of the present invention is as follows:
1, first, when matched moulds state, sprue spurt into the thermoplastic materials of liquid, enter die cavity, pressurize, cooling, plastics screwed pipe molding through sub-runner, cast gate；
2, then, the ambilateral hydraulic cylinder action of mould, drive the core that cross section is circle in slide block mechanism extraction die cavity；
3 it follows that Injection Motor Template, solid plate are opened, and mould active and inactive mold two parts separate, it is possible to output the outer mold surface of described screw propulsion pipe；
4, now, product can be completely out, and the post rod mechanism of injection machine arrives at push piece plate by the hole that ejects of die bottom plate, and the push rod on push piece plate does projecting motion, ejects product；
5, last, after product takes out, Injection Motor Template closes with mould dynamic model part, release link allows push piece bar group return, the ambilateral hydraulic cylinder action of mould, drives slide block mechanism to be inserted into described core, mould is of completely closed, is in matched moulds state, it is possible to inject next time。
The present invention adopts die cavity two halves lobe to close, in cavity surface, processing has semi-spiral structure, creatively said two semi-spiral structure is misplaced involutory, form the outer mold surface of screw propulsion pipe, making depanning simple, the structure being combined to form makes the product of preparation form a transition plane at helicoid intersection, and depanning yield rate is greatly improved, and prepared properties of product are superior, advance the in hgher efficiency of object。Motion for described core, power is provided by making described core-pulling mechanism connect hydraulic cylinder, and described hydraulic cylinder oil cylinder fixed block is arranged on slide block structure, described slide block structure is being made up of spacing slip in chute slide block holder and press strip, it is spacing for carrying out path that described chute end arranges slide block briquetting, described slide block structure arranges jam-packed block and ensures guiding accuracy, ensures that the action of described core is accurately and product quality with this。Described moving platen, solid plate are set to mould two cavity configuration, and once-through operation completes the production of two pieces product and prepares, and thus can further improve nearly one times of work efficiency, and injection hole is reasonable in design, prepare properties of product superior。Present configuration is simple, manufactures, easy for installation, and production efficiency is high, has very strong promotion and use value。
