Abstract
The utility model relates to a full electric injection moulding machine locking mould driving mechanism, which comprises a motor, a ball screw, a transmission nut, a power transmission mechanism driven by the motor to drive the ball screws and the transmission nut to move, and a transmission sleeve barrel which is rotatablely fixed on a supporting seat. The ball screw and the transmission nut are in transmission fit. One end of the transmission sleeve barrel is connected with the power transmission mechanism and the other end of the transmission sleeve barrel is connected with the transmission nut. A section of the ball screw is arranged in an inner cavity of the drive sleeve barrel and the other section is connected with a cross head on a mould opening mechanism through the transmission nut. The utility model has the advantages of simple and reliable structure. The ball screw is comparatively short and shortened by one third of the original ball screw, lowering the manufacturing cost. As the ball screw drives the cross head, a driving mode coincides with the oil cylinder drive of a hydraulic injection moulding machine. Thus the design of a connecting rod mechanism and an ejector mechanism does not need to take account of avoiding the ball screw. Meanwhile, the stroke of an opening-closing mould is increased, increasing the stability of the connecting rod.
Description
Technical field
The utility model relates to a kind of injection moulding machine mode-locking driving mechanism technical field, especially refers to full electric injection molding machine locked mode driving mechanism.
Background technology
For hydraulic injection molding machine; locked mode drives and finishes by hydraulic cylinder; because full electric injection molding machine does not have hydraulic system; come the motion of driven machine fully by motor; be that clamping mechanism is also driven by motor; the function that locked mode drives is to be used for driving crosshead, and is by linkage that mould is closed or open again.
Existing full electric injection molding machine locked mode driving mechanism normally leading screw 8# is fixed on the locked mode tailgate 2# by holder 3#, see shown in Figure 1, motor 6# rotation, motor 6# drives synchronous pulley 4# by timing belt 5#, drive leading screw 8# rotation by synchronous pulley 4#, nut 7# drives crosshead 1#, and it is closed or open to finish mould by linkage again.The core of this design is: leading screw 8# only rotates as support, promotes crosshead 1# by nut 7.Be characterized in: simple in structure, reliable, but rotating shaft 8# is longer, and cost is higher; On the other hand because rotating shaft 8# is longer, and again as support, when design linkage and ejecting mechanism, consider to avoid rotating shaft 8#, cause simultaneously under the same template size, folding line journey reduces, and the less stable of connecting rod, so its structure is still waiting to improve.
Summary of the invention
Technical problem to be solved in the utility model is a kind of simple in structure, firm, operational stability is high and cost of manufacture is low full electric injection molding machine locked mode driving mechanism.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: it comprise ball-screw that motor, a pair of transmission cooperate and transmission nut and by driven by motor to drive the Poewr transmission mechanism of ball-screw and transmission nut motion, it is characterized in that it also includes the drive socket that is rotatably mounted on the supporting base, this drive socket one end links to each other with Poewr transmission mechanism, its other end is connected with transmission nut, described ball-screw one section places the drive socket inner chamber, and another section links to each other with crosshead in the mold open mechanism through transmission nut.
The fixing inner chamber that can place supporting base of above-mentioned drive socket and supporting base, and fixing by bearing mutually for drive socket, and drive socket one end extends the supporting base inner chamber and is connected with Poewr transmission mechanism, and its other end links to each other with transmission nut.
Above-mentioned Poewr transmission mechanism can for motor on the synchronous band that links together of output synchronous pulley and synchronous pulley constitute.
Compared with prior art, advantage of the present utility model is to adopt to rotate with transmission nut and drives ball-screw, promote to open crosshead by ball-screw, when motor rotates, driving synchronous pulley to drive socket by the synchronous pulley on the motor by synchronous band rotates, then drive the transmission nut rotation by drive socket, because of transmission nut is only done the position rotating motion, move back and forth and promote crosshead on the opener thereby promote ball-screw, it is closed or open to finish mould by linkage again.The core of this design is: transmission nut is fixed on conduct support on the sleeve, only rotates, and ball-screw promotes crosshead, is characterized in: simple in structure, reliable; Ball-screw is shorter, shortens 1/3rd than originally, thereby has reduced cost of manufacture; Because ball-screw drives crosshead, its drive form is consistent with the hydraulic oil cylinder driving of hydraulic injection molding machine, therefore, when design linkage and ejecting mechanism, need not consider to avoid ball-screw, and the line of folding simultaneously journey increases, and has also improved the stability of connecting rod.

Fig. 2 is the structure cutaway view of existing electric injection molding machine locked mode driving mechanism;
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this full electric injection molding machine locked mode driving mechanism mainly comprise one be fixed in servomotor 1 on the support 2, one with motor 1 output shaft on the Poewr transmission mechanism of synchronous pulley 11 by constituting with 3 synchronous pulleys that are connected 5 synchronously, ball-screw 4 that a pair of transmission cooperates and the crosshead 8 in transmission nut 9, a drive socket 61 and the mold open mechanism.
Wherein drive socket 61 is installed on the supporting base 6 by bearing, and an end of drive socket 61 and synchronous pulley 5 be connected, and the other end and transmission nut 9 are connected, and supporting base 6 is fixed on the locked mode tailgate 7.Described locking nut 63 is used to compress bearing inner race, and rear end cap 62 is used for the compression axis bearing outer-ring.
One end of described ball-screw 4 is installed in the axis hole of drive socket 61 and transmission nut 9, and the other end passes the locked mode tailgate and links to each other with crosshead 8.
During work, motor 1 rotates, by be with synchronously 3 and synchronous pulley 5 drive drive sockets 61 and transmission nut 9 rotations, thereby promote crossheads 8 by ball-screw 4, finish the closed of mould and open through linkage.This driving mechanism is owing to adopt ball-screw 4 to drive crosshead 8, thereby can make ball-screw 4 contraction in lengths, and cost reduces, folding line journey increases, connecting rod stability improves thereby make.
