Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, it is therefore an objective to help those skilled in the art that design of the present utility model, technical scheme are had more complete, accurate and deep understanding, and contribute to its enforcement.
As shown in Figures 1 to 6, this utility model provides a kind of swollen bag mold stripping mechanism, including cone core push rod 2, punch fixed core cylinder 3, workpiece positioning sleeve 4 and demoulding push rod 1；Cone core push rod 2 is moveable setting, and punch fixed core cylinder 3 is sheathed on cone core push rod 2；Workpiece positioning sleeve 4 is sheathed on punch fixed core cylinder 3, is used for holding workpiece, and is moveable setting；Demoulding push rod 1 is for cone core push rod 2 is applied active force, makes cone core push rod 2 promote punch fixed core cylinder 3 and workpiece positioning sleeve 4 synchronizing moving, and makes workpiece depart from the spacing zone of swollen bag stop collar 9.
Specifically, as depicted in figs. 1 and 2, cone core push rod 2 be T-shaped, and it includes the guide section 21 that inserts in punch fixed core cylinder 3 and is connected with guide section 21 lower end and for promoting the first promotion section 22 of punch fixed core cylinder 3, the diameter of the first promotion section 22 is more than the diameter of guide section 21.Guide section 21 is the cylindrical structural that length is longer, and the first promotion section 22 is disc-shaped structure, and first promotes section 22 and guide section 21 for being fixedly and coaxially connected.
As shown in figures 1 and 3, punch fixed core cylinder 3 is the structure of both ends open, inner hollow, it includes location cylinder 31 and is connected with cylinder 31 lower end, location and for promoting the second of workpiece positioning sleeve 4 to promote section 32, guide section 21 inserts in the cylinder 31 of location after the second promotion section 32, and the internal diameter of workpiece positioning sleeve 4 promotes the external diameter of section 32 less than second.Location cylinder 31 is the cylindrical structural that length is longer, and the length of location cylinder 31 is more than the length of guide section 21, and the second promotion section 32 is disc-shaped structure, and second promotes section 32 and location cylinder 31 for being fixedly and coaxially connected.Swollen bag mould also includes punch 10 and cone core 11, and punch 10 is placed in cylinder 31 inside, location with boring core 11, and punch 10 conical surface is inserted the punch on the cylinder 31 of location down and fixed in groove, bores core 11 and is installed on the top of punch 10.
As shown in Figure 1 to Figure 3, the external diameter of location cylinder 31 is less than the internal diameter of workpiece positioning sleeve 4, and both are matched in clearance, positions between cylinder 31 and workpiece positioning sleeve 4 and forms the space holding workpiece, and workpiece is the oil storage cylinder of vibroshock.The centre bore bottom inside of workpiece positioning sleeve 4 has a step, step place forms the locating surface of an annular, when workpiece is placed, it is enclosed within outside punch fixed core cylinder 3, it is inserted to downwards locating surface, the location of workpiece contacts with the locating surface of its lower surface with workpiece positioning sleeve 4, and this locating surface is the positioning datum of swollen bag axial location.
As it is shown in figure 1, swollen bag mold stripping mechanism of the present utility model also includes the die holder 5, mould fixed glides 7 and the fixing guide rail base plate 6 that set gradually.Swollen bag stop collar 9 is bolted on die holder 5, and die holder 5 is bolted in mould fixed glides 7, and mould fixed glides 7 is bolted on fixing guide rail base plate 6, and fixing guide rail base plate 6 is bolted on equipment workbench 8.Mould fixed glides 7 and fixing guide rail base plate 6 are respectively provided with the centre bore holding cone core push rod 2, and die holder 5 and swollen bag stop collar 9 are respectively provided with the centre bore holding punch fixed core cylinder 3.
As preferably, as shown in Figure 1, the pore size of the centre bore of mould fixed glides 7 and the centre bore of fixing guide rail base plate 6 is equal, and the diameter of the centre bore of mould fixed glides 7 and fixing guide rail base plate 6 promotes the diameter of section 22 slightly larger than first, cone core push rod 2 constitutes matched in clearance with mould fixed glides 7 and fixing guide rail base plate 6.
As preferably, as it is shown in figure 1, the diameter of the centre bore of mould fixed glides 7 promotes the overall diameter of section 32 more than second, during original state, mould fixed glides 7 holds punch fixed core cylinder 3, thus spending punch fixed core cylinder 3 to form supporting role.Die holder 5 inside center hole is stepped hole, and the diameter in die holder 5 bottom centre hole promotes the overall diameter of section 32 slightly larger than second, and punch fixed core cylinder 3 and die holder 5 constitute matched in clearance.
As preferably, as it is shown in figure 1, in the axial direction, having the space allowing workpiece positioning sleeve 4 be axially moveable between die holder 5 and swollen bag stop collar 9, workpiece positioning sleeve 4 also keeps the relation of matched in clearance with die holder 5.When state shown in Fig. 4, workpiece positioning sleeve 4 and punch fixed core cylinder 3 are in bottom dead center position place, the bottom surface of swollen bag stop collar 9 and second promotes the length more than workpiece positioning sleeve 4 of the vertical dimension between the end face of section 32, so that it is guaranteed that workpiece positioning sleeve 4 can move up.When punch fixed core cylinder 3 promotes workpiece positioning sleeve 4 to move, workpiece positioning sleeve 4 drives workpiece to synchronize to move up, and finally makes workpiece depart from the spacing zone of swollen bag stop collar 9.
As shown in Figure 4, swollen packet compression on earth time position, it can be seen that the cone lower surface of core push rod 2, the lower surface of punch fixed core cylinder 3 and the lower surface of workpiece positioning sleeve 4 respectively fall in the upper plane of equipment workbench 8, the upper plane of mould fixed glides 7 and die holder 5 on step surface.Demoulding push rod 1 upper surface is lower than the upper plane of equipment workbench 8.
As it is shown in figure 5, under take blame for others on top time, state when punch is retired, be clear to demoulding push rod 1 and cone core released by boring core push rod 2, punch bounces back, and the step surface of cone core push rod 2 just contacts with the bottom face of punch fixed core cylinder 3.Being now a critical state, top takes off punch and ejects workpiece is a continuous print process.
As shown in Figure 6, along with under take blame for others the upper top of continuation to a certain moment, punch is retired and state during workpiece convex closure also completely out swollen bag stop collar 9 spacing zone, and now the upper surface of workpiece set fits with the lower surface of swollen bag stop collar 9.
Finally owing to the swollen package location of workpiece has completely disengaged from swollen bag stop collar 9 spacing zone, again because the coordinating of workpiece inner wall and punch fixed core cylinder 3 cylindrical, workpiece outer wall and workpiece positioning sleeve 4 inwall and workpiece outer wall and the swollen non-spacing zone of bag stop collar 9 are matched in clearance, accordingly, it is possible to easily take out workpiece.
Above in association with accompanying drawing, this utility model is exemplarily described.Obviously, this utility model implements and is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present utility model design carries out with technical scheme；Or not improved, above-mentioned design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
