Description
Technical field
The present invention relates to die cast metal and injection-moulding plastic, is telecontrolled aircraft beveled wheel mold.
Background technology
At present, beveled wheel mold shaping on the mold mechanism that adopts have the following two kinds: 1. split slide block is shaping.It is utilize two can be movable slide block split shaping, the slide block of latter two shaping split does the action of loosing core of mould two sides in the guide runner of moving platen, reach the object that article outer surface and slide block moulding section depart from, then complete deviating from of goods by ejecting mechanism.The mould structure of this mechanism is simple, and pressure transmits, but shaping owing to being employing two split slide block, therefore goods has obvious matched moulds vestige, directly affects the quality of goods, easily occurs that two slide blocks are stuck in guide runner, cause the problem that mould is scrapped simultaneously.2. mould right-hand side work point from mold mechanism.It is before mould matched moulds is shaping, by manually being installed in a mold by inserts, after moulding by casting, by mould pushing-off mechanism, goods outside launch mode, is then separated goods outside mould by workman together with inserts with inserts.Though this mould structure action is solid and reliable, mould structure is simple, but labor strength is large, and production efficiency is low, simultaneously workman install inserts in a mold time, safety can not get ensureing.In order to overcome the deficiency of above-mentioned mould, I spy provides following a kind of mould to solve problem.
Summary of the invention
The present invention is to provide telecontrolled aircraft beveled wheel mold, and this mould utilizes bearing to take off helical gear, utilizes cylinder secondary to eject.Dynamic mould core and moving die insert cooperation place are designed to oil groove, unload in helical gear process can increase steadily, smooth degree.Push rod hook is contained in the middle of two packing rings, and push rod and packing ring adopt matched in clearance.Dynamic mould core and packing ring close-fitting, in case deviate from running in process at helical teeth and affect deviating from of helical teeth.The hole shape of the shaping centre of head of dynamic mould core (29), bottom is screwed between rolling bearing and backing plate.In forming process, this core is motionless, and in ejection process, this core plays connection function, with product motions under the effect of rolling bearing.By hydraulic oil cylinder driving one-level ejecting mechanism during the demoulding, utilize the flexibility of rolling bearing, dynamic mould core rotates to deviate from smoothly from helical teeth die cavity to Impact direction together with goods.Telecontrolled aircraft beveled wheel mold, solves split slide block mould mechanism, goods has obvious matched moulds vestige, directly affects the quality of goods and the problem of the easy stuck mold damage of slide block.Solve mould right-hand side work point from mold mechanism, labor strength is large, and production efficiency is low, and safety of workers can not get the problem ensured.Telecontrolled aircraft beveled wheel mold, it is characterized in that: cover half sprue puller (17) is arranged on after on top clamping plate (15) and is slidably matched with stripper plate (14), centring ring (16) is fastened on soket head cap screw in the stepped hole of top clamping plate (15), controlled interval pull rod (19) is fastened on stripper plate (14), guide pillar (20) be fastened on top clamping plate (25) upper and then with solid plate (13), dynamic model backing plate (11) is slidably matched, first push pedal backing plate (2) and the first push pedal (3) are fastenedly connected with soket head cap screw, use nut (7) fastening again after second push pedal backing plate (8) is connected with oil cylinder (10) with the second push pedal (9), push rod (32) is arranged in the first push pedal (3), be arranged in the space of the first push pedal (3) and the first push pedal backing plate (2) by thrust rolling bearing (31), annular bearing with rolling contact (30) is arranged in the space of the second push pedal (9) and the second push pedal backing plate (8), release link (33) is arranged on the first push pedal (3) and goes up and become glade plane space to coordinate with the second push pedal (9) with the second push pedal backing plate (8), moving die insert (27) becomes matched in clearance with dynamic mould core (29), first fixed mold (25) coordinates with the second fixed mold (26) glade plane space, moving die insert (28) and dynamic mould core (29) matched in clearance, the mould bases guide pin bushing (36) be arranged on solid plate (13) coordinates with bearing type die set guide pin (34) glade plane space be arranged on moving platen (11).

Detailed description of the invention:
Telecontrolled aircraft beveled wheel mold, it utilizes bearing to take off helical gear, utilizes cylinder secondary to eject.After mould has been debugged in injector or die casting machine, matched moulds, through pressurize, die sinking after cooling, due to dynamic model, cover half is under the effect of pin (12), mould carries out a die sinking from I-I, the solidifying material of cast gate is in stripper plate (14), under the acting in conjunction of sprue puller, dynamic model, cover half separately, i.e. II-II place twice parting, after die sinking completes, oil cylinder (10) is started working, in oil cylinder, oil pressure reduces, piston moves to cover half direction and is released by ejecting mechanism, now dynamic mould core (29), annular bearing with rolling contact (30), dynamic mould core (29) is driven to rotate under the acting in conjunction of thrust rolling bearing (31), goods are screwed out, injector or die casting machine push rod ejecting mechanism, under push rod (32) effect, goods are released.Before matched moulds, the oil pressure in oil cylinder (10) increases, and oil cylinder piston moves down, and ejecting mechanism and dynamic mould core (29) are first resetted, and ejecting mechanism is resetted by release link, enters the moulding by casting in next cycle after reset.
