Abstract
The utility model provides a helical gear class work piece shedder, includes fixed die plate (1) and movable mould board (2), is provided with fixed mold (3) in fixed die plate (1), is provided with movable mold (4) in movable mould board (2), and fixed mold (3) match its characterized in that with movable mold (4): movable mold (4) outer joint have driving tooth (5), be provided with moving die insert (6) in movable mold (4), moving die insert (6) and fixed mold (3) form die cavity (7) jointly, die cavity (7) back and fixed mold (3) contact are run through in centibar (8) that lie in movable mold (4), and outside centibar (8) movable cup jointed sleeve (9) still, movable mold (4) and movable mould board (2) between can rotate relatively and the axial float.
Description
Technical field
The utility model relates to a kind of mold releasability structure, particularly a kind of screw thread class workpiece stripper apparatus.
Background technology
In modern mechanical transmission, gear drive, because of compared with other transmission mechanisms, has compact conformation, reliable operation, production efficiency is high and can ensure the advantages such as constant gearratio and be widely used.And helical gear is compared with Spur Gear Driving, its transmission is more steady, institute is hit less, is more suitable in high-speed drive environment, is therefore widely used in the various fields such as movement, clock and watch, instrument.
But because helical gear article shape is special, in injection mo(u)lding is produced, by traditional simple die sinking mode, goods cannot be taken out from mold cavity, the die sinking mode of traditional simple linear motion type or shaping goods can be damaged, or mould itself will be destroyed.Therefore the production utilizing the mode of injection moulding to carry out helical gear can be very restricted.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of structure simple, designs ingenious, can complete the stripper apparatus of helical gear class workpiece stripping operation smoothly.
Technical solution of the present utility model is: a kind of helical gear class workpiece stripper apparatus, comprise solid plate 1 and moving platen 2, fixed mold 3 is provided with in solid plate 1, dynamic mould core 4 is provided with in moving platen 2, and fixed mold 3 and dynamic mould core 4 match, it is characterized in that: be externally connected with driving tooth 5 at described dynamic mould core 4, moving die insert 6 is provided with in dynamic mould core 4, moving die insert 6 and fixed mold 3 form die cavity 7 jointly, the center-pole 8 being positioned at dynamic mould core 4 runs through die cavity 7 and contacts with fixed mold 3 afterwards, and outside center-pole 8, go back movable sleeve be connected to sleeve 9, can relatively rotate and axial float between described dynamic mould core 4 and moving platen 2.
Compared with the existing technology, tool has the following advantages the utility model:
The helical gear class workpiece stripper apparatus of this kind of version, its structure is simple, designs ingenious, rationally distributed.It is difficult to the problem of the smooth demoulding after the moulding by casting carrying out helical gear class workpiece for traditional injection mold, design a kind of special stripping structure, first it drive between workpiece and the insert be in direct contact with it and relatively rotate, and utilize this rotation workpiece and insert to be departed from, then cover half is pulled and is separated with moving platen, when utilizing this device to carry out the stripping operation of helical gear class workpiece, no matter be that workpiece or mould all can not sustain damage, its manufacture craft is simple simultaneously, cheap for manufacturing cost, therefore this stripper apparatus has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment state one.
Fig. 2 is the structural representation of the utility model embodiment state two.
Fig. 3 is the structural representation of the utility model embodiment state three.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.As Fig. 1, Fig. 2, shown in Fig. 3: a kind of helical gear class workpiece stripper apparatus, comprise solid plate 1 and moving platen 2, fixed mold 3 is provided with in solid plate 1, and in moving platen 2, be provided with dynamic mould core 4, and above-mentioned fixed mold 3 is relative with between dynamic mould core 4, match, driving tooth 5 is externally connected with at dynamic mould core 4, this driving tooth 5 can drive dynamic mould core 4 to rotate relative to moving platen 2, moving die insert 6 is provided with in this dynamic mould core 4, moving die insert 6 and fixed mold 3 form die cavity 7 jointly, the material of melting enters the rear cooling of die cavity 7 and forms workpiece (i.e. helical gear 10), center-pole 8 is also provided with in dynamic mould core 4, this center-pole 8 contacts with fixed mold 3 after running through die cavity 7, and outside center-pole 8, go back movable sleeve be connected to sleeve 9, relative axial float can also be there is in above-mentioned dynamic mould core 4 with between moving platen 2.
The course of work of the helical gear class workpiece stripper apparatus of the utility model embodiment is as follows: first, cover half pull 1 and moving platen 2 be in and close up state, the material of melting enters die cavity 7, helical gear 10(and workpiece is formed) after cooling, driving tooth 5 is now first driven to rotate, under the drive of driving tooth 5, dynamic mould core 4 also can together rotate, pull on 1 because now helical gear 10 withstands on cover half under the effect of center-pole 8, therefore helical gear 10 can not rotate along with dynamic mould core 4, so just be equivalent to relatively rotate between dynamic mould core 4 and helical gear 10, in the process of rotating, dynamic mould core 4 is descending relative to moving platen 2, helical gear 10 screws out from moving die insert 6,
Moving platen 2 and cover half disengage between pulling 1 afterwards, and then sleeve 9 is up relative to center-pole 8, and ejected from center-pole 8 by the helical gear 10 be socketed on center-pole 8, helical gear 10 is taken away by operating personnel;
Dynamic mould core 4 gets back to initial position, and cover half pull 1 and moving platen 2 again close up, wait for material inject die cavity 7, carry out next workpiece injection mo(u)lding operation.
