Abstract
The invention provides a demoulding structure of a 3-plate mould for threaded products, and aims to realize the purposes that two products can be one-step formed in one mould, the production efficiency is improved, labor time of workers is saved, and time and labor are saved. The demoulding structure includes a gate plate, an A plate, a B plate, a support plate, front mould cores, rear mould cores, front mould inserts and rear mould inserts, wherein the gate plate is in press fitting with the A plate; the A plate is in press fitting with the B plate; the gate plate is fastened and connected with the A plate. The demoulding structure is characterized in that the two groups of the front mould cores, the rear mould cores, the front mould inserts and the rear mould inserts are positioned in two chambers of the A plate and the B plate respectively, and are combined to form two cavities; the rear mould inserts are inserts with external threads at the upper parts particularly; the support plate includes a top support plate and a bottom support plate particularly; the B plate is supported at the top support plate; the lower parts of the rear mould inserts adopt rotating shaft structures, and are supported at the top support plate and the bottom support plate through bearings respectively; the middle parts of the rotating shaft structures are sleeved with driven gears.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially a kind of demolding structure of screw product of three template dies.
Background technology
Existing inwall is with the product of helicitic texture, while making by three template dies, it all has in a mould die cavity only is set, and threaded mold insert is placed in die cavity, when the needs demoulding, guide pillar drives threaded mold insert and rotates, and makes the product helical rotation break away from threaded mold insert, owing to only having a die cavity in a mould, it makes when this kind of product of a large amount of production of needs, its production efficiency is low, needs workman's working time long, wastes time and energy.
Summary of the invention
The invention provides a kind of demolding structure of screw product of three template dies, it makes in a mould can two products of one-shot forming, have improved production efficiency, have saved working time, time saving and energy saving of workman.
A kind of demolding structure of screw product of three template dies, its technical scheme is such: it comprises water gap plate, the A plate, the B plate, supporting plate, front cavity, rear cavity, the front mould mold insert, the rear mold mold insert, described water gap plate press-fits in described A plate, and the piling of described A plate is in described B plate, and described water gap plate is fastenedly connected described A plate, it is characterized in that: two groups of described front cavitys, rear cavity, the front mould mold insert, the rear mold mold insert lays respectively at described A plate, the B plate two cavitys in, be combined to form two die cavities, the rear mold mold insert is specially top with externally threaded mold insert, and described supporting plate specifically comprises mounting plate, bottom plate, described B plate is supported on described mounting plate, and the bottom of described rear mold mold insert is pivot structure, it is supported on described mounting plate by bearing respectively, bottom plate, the middle part of described pivot structure is set with driven gear, in the middle of two corresponding driven gears in die cavity bottom, is provided with driving gear, described driven gear, driving gear all is positioned at described mounting plate, in the installation cavity that bottom plate is combined to form, described driving gear meshes respectively the described driven gear of both sides, and the center of described driving gear has internal thread, and the head location of the axis of guide is in the draw-in groove of described A plate, and the bottom of the described axis of guide is run through the A plate successively, the B plate, mounting plate, the center of driving gear, bottom plate, all have external screw thread below the middle part of the described axis of guide, the external screw thread of the described axis of guide and the center of described driving gear are threaded.
After adopting structure of the present invention, the above partly first and water gap plate of water gap plate breaks away from, water gap plate drives A plate, front cavity, the rising of front mould mold insert afterwards, simultaneously due to the head location of the axis of guide in the draw-in groove of described water gap plate, the axis of guide is driven and moves upward, because the external screw thread of the axis of guide and the center of described driving gear are threaded, driving gear rotates, now, the driven gear that driving gear drives both sides rotates and then makes rear mold mold insert unitary rotation, product in die cavity is produced along the external screw thread of rear mold mold insert, completes the demoulding; It makes in three plate moulds can two products of one-shot forming, have improved production efficiency, have saved working time, time saving and energy saving of workman.
The accompanying drawing explanation
Fig. 1 is elevation view structural representation sketch of the present invention.
