The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment of clamping apparatus, structure, feature and effect thereof according to the direct press type injection machine that the utility model proposes, describe in detail as after.
See also Fig. 1, Fig. 2, shown in Figure 3, the clamping apparatus of the utility model direct press type injection machine, it mainly comprises: it mainly comprises a plate 4, middle plate 3, rob support 1 three big critical pieces; Plate 4 is fixed on the frame 9, four jiaos at a plate 4 respectively are provided with a high-voltage lock mould oil cylinder 5, the both sides of plate 4 respectively are provided with a direct express Mode-locking oil cylinder 7, and plate 3 and sliding assembly 8 slidably reciprocated and finish the action of quickly unlocking mould at the axis direction of the guide rail upper edge of frame 9 pull bar 2 during the piston rod of this direct express Mode-locking oil cylinder 7 drove; Pull bar 2 one ends pass a plate 4 and piston 6 are housed, and the other end passes middle plate 3, are supported by rob support 1, and rob support 1 is slidingly mounted on the guide rail of frame 9; And the certain position of pull bar 2 is provided with at least one screw thread 16 and four row chutes 17, and this screw thread 16 circumferentially evenly is being divided into four row by four row chutes 17, and be contained in locking nut 15 on the plate 3 match and realize locking and throw off.
Above-mentioned injection moulding machine mode-locking device, the screw thread on its pull bar also can be one, or more than two, but two is best.
As Fig. 2, Fig. 3, Fig. 4, Fig. 5, be located at the screw thread 16 of pull bar 2 certain positions, circumferentially evenly be divided into four row by four row chutes 17, described locking nut 15 also within it the surface two internal threads 18 and four row chutes 19 are axially arranged, the chute 19 that this internal thread 18 also is arranged on it circumferentially is divided into four row.As Fig. 4, shown in Figure 5, when pull bar 2 screw threads row and locking nut 15 screw thread column alignments, screw thread 16 and screw thread 18 engagements, pull bar 2 axially fastens plate 3 high-voltage lock moulds in the drive with locking nut 15.After locking nut 15 rotated 45 ° along axis, as Fig. 5, the screw thread row staggered with row, and screw thread 18 can slide in chute 17 vertically, and middle plate 3 is promptly thrown off with pull bar 2, and middle plate 3 can be finished the action of quickly unlocking mould under direct express Mode-locking oil cylinder 7 drives.The linkages of being made up of jointly two folding oil cylinders 14 and two connecting rods 10 are installed on four locking nuts 15 and are driven by it, thus, four locking nuts 15 can rotate 45 along its axis separately, and its anglec of rotation nut limited block 12 that is locked is defined as two angles between the inductive switch 13.When travel switch 11 arrived step position, pull rod screw 16 left side, locking nut 15 promptly was positioned at and pull bar 2 screw threads 16 positions of engagement, and folding oil cylinder 14 just can move to finish throws off or snap action.The characteristics of this structure are: have only two screw threads 16 on the pull bar 2, processing is simple, and can make special shape, satisfying force request, thereby prolongs the life-span of pull bar.
Because technologic needs, require the locked mode process to be divided into quick locked mode and high-voltage lock mould, to enhance productivity and to reach the requirement of moulding process, plate 3 was thrown off with pull bar 2 during the utility model at first made, finish the action of quick locked mode by direct express Mode-locking oil cylinder 7, the dynamic model in being fixed on the plate 3 and the cover half that is fixed on a plate 4 very near the time make it to stop.Rely on locking nut shown in Figure 2 mechanism make in plate 3 and pull bar 2 engagements, then high-voltage lock mould oil cylinder 5 left chambeies fill hydraulic oil drive in plate 3 finish the action of high-voltage lock mould.High-voltage lock mould oil cylinder 5 left chamber releases after the formed product, right chamber are oil-filled push back in plate 3 make locking nut mechanism removal load, plate 3 was thrown off with pull bar 2 during the locking nut mechanism action made, then the die sinking process is finished in the action of direct express Mode-locking oil cylinder.
According to the thickness of mould, can finish the mode transfer action producing qualified products by the position of piston 6 in oil cylinder of regulating high-voltage lock mould oil cylinder 5, thereby simplify the structure of whole device, also reduced cost.
The technological innovation of the clamping apparatus of the direct press type injection machine of the present utility model that above-mentioned structure like this constitutes all has many saving graces for technical staff of the same trade now, and the progressive that possesses skills really.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but every technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
