Description
Technical field
The present invention relates to a kind of retaining mechanism of bottle blowing machine, particularly relate to a kind of bed die retaining mechanism of bottle blowing machine.
Background technology
Bottle blowing machine is the equipment in the plastic bottle processing and manufacturing fields such as beverage bottle, oil bottle, medicine bottle.Bottle blowing machine comprises left mould, right mould and bed die, the bottle die cavity that three coordinates formation one complete.During work, open left and right mould and bed die and bottle base is placed within die cavity, close left and right mould and bed die again, blowing processing is carried out to bottle base, left and right mould and bed die is opened after complete bottle to be processed is shaping, now bed die declines and exits cavity positions, and the bottle after machining is taken away and delivered to next procedure.Need to be locked after bed die exits die cavity, existing bed die retaining mechanism as shown in Figure 1, comprise the base plate 101 be fixed on mould rack, be fixed on the valve body 102 on base plate 101 end face, closed containing cavity 103 is had between base plate 101 and valve body 102, the lower end connecting the bed die blind rivet 104 of bed die is placed in closed containing cavity 103, adapter sleeve 105 on the lower end being placed on bed die blind rivet 104 is also housed in closed containing cavity 103, with the piston 106 be placed on outside adapter sleeve 105, the outer wall of piston 106 pushes against the inwall of closed containing cavity 103, the snap joint 107 passing into gas base plate 101 is also equipped with, valve body 102 has the interface channel 108 of the closed containing cavity 103 be communicated with above snap joint 107 and piston 106, compression spring 109 is equipped with in the below of piston 106, on the outer wall of the lower end of bed die blind rivet 104, piston 106 is placed on the inwall on adapter sleeve 105 and all has groove, adapter sleeve 105 has the groove being communicated with the groove of bed die blind rivet 104 and the groove of piston 106, steel ball 110 is placed with in groove, steel ball 110 be rollably placed in clamp between bed die blind rivet 104 to adapter sleeve 105 or between adapter sleeve 105 and piston 106 and by two corresponding parts fixing.
During work, low pressure gas is from the closed containing cavity 103 of snap joint 107 above interface channel 108 enters piston 106, the pressure of low pressure gas forces piston 106 to move downward, when the groove of piston 106 is relative with steel ball 110, because bed die blind rivet 104 drives bed die to move upward, extrude the former steel ball 110 be placed between bed die blind rivet 104 and adapter sleeve 105 and enter in the groove of piston; After bottle blowing terminates, bed die blind rivet 104 drives bed die to decline, low pressure gas stops being filled with, piston 106 moves upward under the effect of compression spring 109, when the groove of bed die blind rivet 104 is relative with steel ball, piston 106 extrudes the former steel ball 110 be placed between adapter sleeve 105 or between adapter sleeve 105 and piston 106 and enters in the groove of bed die blind rivet 104, and now steel ball 110 is by bed die blind rivet 104 and the stuck locking of adapter sleeve 105.Bottle blowing machine all can produce vibration in the whole course of work, bed die retaining mechanism vibrates thereupon, this makes steel ball and piston inboard groove produce strong extruding and friction, thus cause the damage of steel ball or break and the wearing and tearing of piston inboard groove, the locking effect of retaining mechanism is caused to reduce, even lost efficacy, and the replacement operation of steel ball and piston is complicated and difficult, greatly affects the use of bottle blowing machine.
Summary of the invention
The technical problem to be solved in the present invention is to provide the blowing machine bottom mold retaining mechanism that a kind of structure is simple and durability is stronger, to make it durable in use, and not easily loss, and reduce costs.
Blowing machine bottom mold retaining mechanism of the present invention, comprise and be fixed on base plate in bottle blowing machine frame and the bed die blind rivet being connected bed die, the outer wall of bed die blind rivet has locating slot, the moving block of strap cam curve base plate is equipped with, there is the latch segment of the locking bed die blind rivet rotated around the alignment pin be fixed on base plate, latch segment is provided with and snaps in locating slot and the locking head be fixed, moving block rotate time its on cam curve drive latch segment rotate and locking head is snapped in or exits locating slot, also have drive moving block rotate drive unit.
Blowing machine bottom mold retaining mechanism of the present invention, the outer wall of the bed die blind rivet be connected with bed die is provided with locating slot, base plate is equipped with the latch segment of locking bed die blind rivet, latch segment is then snapped in locating slot bed die blind rivet to lock by the locking head arranged thereon.During work, drive unit drives moving block to rotate, and cam curve on it drives latch segment to rotate around alignment pin, when latch segment rotates to precalculated position, is locked by bed die blind rivet in the locating slot that the locking head on it snaps in bed die blind rivet; When lock complete need unlock time, drive unit drive moving block return back to original position, the cam curve on it then can drive latch segment to rotate, until locking head exits locating slot, thus completes unblock.This blowing machine bottom mold retaining mechanism to be coordinated with bed die blind rivet by latch segment fixingly to realize locking, and its structure is very simple; Parts are larger and firm block structure, have better wearability and durability, not easily cause loss, are conducive to improving reducing costs service life; Parts are arranged on base plate but not it is inner, its operation safeguarded and change of being more convenient for, and improve maintenanceability and and can reduce maintenance difficulties, advantageously in the normal use of bottle blowing machine.
