Abstract
The invention provides a spiral one-mold double-cavity ejection structure. According to the invention, two products can be formed in one mold at the same time, the production efficiency is improved, the labor time of workers is saved, and time conservation and labor conservation are realized. The spiral one-mold double-cavity ejection structure comprises a front mold, a rear mold, rear mold inserts, a plate A and a plate B, wherein external threads are arranged on the rear mold inserts; the spiral one-mold double-cavity ejection structure is characterized in that two cavities are formed between the front mold and the rear mold; external thread parts of the corresponding rear mold inserts are respectively positioned in the two cavities; the lower parts of the rear mold inserts are in fastening connection with rotating shafts; the middle of a whole body formed by each rear mold insert and each rotating shaft is mounted in the plate B through bearings; the lower parts of the rotating shafts are exposed outside the plate B and positioned in a cavity formed between the plate B and a backing plate; transmission gears are mounted at the parts, positioned in the cavity, of the rotating shafts in a sleeving way; an intermediate gear is positioned at the middle part between the two transmission gears, and is in meshed connection with the transmission gears on the two sides respectively; an intermediate rotating shaft is sleeved with the intermediate gear.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially a mould two-chamber spiral ejecting structure.
Background technology
Existing inwall is with the product of helicitic texture, it all has in a mould die cavity only is set, threaded mold insert is placed in die cavity, and when the needs demoulding, guide pillar drives threaded mold insert and rotates, make 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, and its production efficiency is low, need workman's working time long, waste time and energy.
Summary of the invention
The invention provides a mould two-chamber spiral ejecting structure, 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.
One mould two-chamber spiral ejecting structure, its technical scheme is such: it comprises front mould, rear mold, the rear mold mold insert, the A plate, the B plate, described rear mold mold insert, for being with externally threaded mold insert, is characterized in that: described front mould, form two die cavities between rear mold, the male thread portion of corresponding described rear mold mold insert lays respectively in two described die cavities, and the bottom of described rear mold mold insert is fastenedly connected with turning cylinder, described rear mold mold insert, the whole middle part of turning cylinder is installed in described B plate by bearing, and the bottom of described turning cylinder exposes to described B plate, and be positioned at described B plate, in cavity between backing plate, the part that described turning cylinder is positioned at described cavity is set with travelling gear, and idler gear is positioned at the centre position of two described travelling gears, it is connected with a joggle with the travelling gear that is positioned at both sides respectively, and described idler gear is set in intermediate rotary shaft, and described intermediate rotary shaft is positioned at cavity, and the two ends of described intermediate rotary shaft are positioned described B plate by bearing respectively, in backing plate, backing plate is run through in the bottom of one of them described turning cylinder, be connected with rotary electric machine by shaft coupling after base plate.
It is further characterized in that: the outer face that is positioned at described rear mold of described rear mold mold insert is set with wear-resisting location guide pin bushing.
After adopting structure of the present invention, after current moulding/demoulding, electric machine rotation, driving the turning cylinder driven rotates, and then drive corresponding travelling gear and rotate, this travelling gear drives idler gear and rotates, and then drive another travelling gear and rotate, it makes two rear mold mold inserts rotate, because the product in die cavity has formed internal thread, it can move upward under the rotation with externally threaded rear mold mold insert, finally make product and rear mold mold insert break away from, it makes in a mould can two products of one-shot forming, improved production efficiency, saved workman's working time, time saving and energy saving.
The accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention.
