An molding injection mechanism of complete electrical injection machine comprises an injection platform, a base of injection platform, a machine barrel, a chute, an injection device and a pre-mould device; wherein, the injection device comprises an injection motor, an injection belt wheel and a ball screw rod; the pre-mould device consists of a pre-mould motor, a screw and an injection shaft; the base of injection platform has a slide rail; the pre-mould device and the injection device are arranged on the same slide seat which can move straightly along the slide rail; a nut of injection device which is transmission matched with the ball screw rod is fixed on the base of the injection platform. The advantages of the utility model are: as the pre-mould device and the injection device are arranged on the same slide seat which can move straightly along the slide rail, the utility model is not only has a simple structure, less parts and low cost, but also has a compact structure, great steadiness and great dynamic property.
Description
Technical field
The utility model relates to the injecting mechanism in a kind of full electric injection molding machine.
Background technology
The function of injection mechanism of injection machine mainly is that plastics are carried out preformed (with plastic molting), and the plastics of fusing are expelled in the mould.For hydraulic injection molding machine, preformed is finished by hydraulic motor, and injection is finished by oil cylinder.Because full electric injection molding machine does not have hydraulic system, injection and preformed are finished by motor-driven.Structure as shown in Figure 3 and Figure 4, its pre-molding apparatus is installed in to be penetrated on the platform two plate 2#, injection device is installed in to be penetrated on the platform tailgate 4#.During injection, injecting motor 5# rotation, by synchronous pulley 10# and the ball-screw nut of band drive synchronously 9# rotation, ball-screw promotes to penetrate platform three plate 3# and moves along guide post 6#, promotes to be installed in the pre-molding apparatus of penetrating on the platform two plate 2# again and finishes injection.During preformed, preformed motor 8# rotation, by synchronous pulley 7# and synchronously band drive preformed screw rod 1# rotation, injection moulding motor 5# is cooperating the rollback of preformed screw rod 1# by above-mentioned injection driving-chain, finishes preformed.The characteristics of this structure are: simple in structure, reliable, but physical dimension is bigger.In addition in this structure, because motion parts two plate 2#, three plate 3# all are to slide on guide post, so bad dynamic performance when motion.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of compact conformation, full electric injection molding machine injecting mechanism that dynamic property is good are provided at above-mentioned prior art present situation, and it can overcome in the prior art effectively, and on the different motion plate caused structure is cumbersome because pre-molding apparatus and injection device split, the defective of bad dynamic performance etc.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: it comprises She Tai, penetrates platform base, machine barrel, hopper and injection device and pre-molding apparatus, wherein injection device includes injecting motor, injection belt wheel and ball-screw, pre-molding apparatus includes preformed motor, screw rod and injection shaft, it is characterized in that: the described platform base of penetrating is provided with slide rail, described pre-molding apparatus and injection device are installed in can be along on the same slide of slide rail moving linearly, is fixed in and penetrates on the platform base and wherein make the transmission nut engaged with ball-screw in the injection device.
Above-mentioned injecting motor and preformed motor can be the parallel rear portion that is fixed on slide, described ball-screw is the both sides of two and in the pre-molding apparatus screw rod of being arranged in parallel, one end of ball-screw all be fixed in the nut engages of penetrating on the platform base, the other end all is installed in rotation in the axis hole of slide, and its end of stretching out links to each other with motor with being with synchronously by synchronous pulley.
In order to make slide art skating back and forth better on slide rail, above-mentioned slide with penetrate platform base joint and also can be provided with line slideway auxiliary.
Compared with prior art, advantage of the present utility model is to adopt penetrates the platform base and is provided with slide rail, described pre-molding apparatus and injection device are installed in can be along on the same slide of slide rail moving linearly, is fixed in and penetrates on the platform base and wherein make the transmission nut engaged with ball-screw in the injection device.This design is owing to be fixed on injection shaft, injection moulding motor and preformed motor on the same slide, do not need guide post, not only designs simplification, parts few, reduce cost of manufacture, and have compact conformation, its size makes the complete machine outward appearance become small and exquisite attractive in appearance again than original minimizing 1/3rd; Again owing to adopt penetrating platform base rear upper surface and be fixed with slide rail, and this slide rail is line slideway, and the slide motion is lighter and handier, thereby dynamic property is greatly improved.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, this reality comprises example and penetrates platform 9, penetrates platform base 7, machine barrel 1, hopper 73 and injection device and pre-molding apparatus, penetrating platform base 7 is fixed in and penetrates on the platform 9, wherein injection device includes injecting motor 4, injection belt wheel 61 and ball-screw 6, pre-molding apparatus includes preformed motor 5, nut 74 and injection shaft 3, the described platform base 7 of penetrating is provided with slide rail 71, is equipped with slide 8 on the slide rail 71, and is provided with guideway 72 at slide 8 and slide rail 71 joints.Described pre-molding apparatus and injection device are installed on the slide 8, are fixed in and penetrate on the platform base 7 and wherein make transmission nut engaged 74 with ball-screw 6 in the injection device.
As shown in Figure 2, described injecting motor 4 and preformed motor 5 are the parallel rear portion that is fixed on slide 8, described ball-screw 6 is the both sides of two and in the pre-molding apparatus screw rod 2 of being arranged in parallel, one end of ball-screw 6 all be fixed in the nut of penetrating on the platform base 7 74 and engage, the other end all is installed in rotation in the axis hole of slide 8, and its end of stretching out by synchronous pulley 61 be with 41 to link to each other synchronously with injecting motor 4.
Its operation principle of full electric injection molding machine injecting mechanism of the present utility model is, problem at above-mentioned existence, now injection device and pre-molding apparatus are installed on the same slide 8, and with line slideway 71 is guiding, because nut 74 is fixed on and penetrates on the platform base 7, ball-screw 6 is installed on the slide 8 during injection, when injecting motor 4 rotations, by being with two ball-screws 6 of 41 drives to rotate synchronously synchronously, pulling slide 8 moves along line slide rail 71, finishes injection.During preformed, pre-molding apparatus and injection device are installed on the same slide 8, when 5 rotations of preformed motor, by being with 51 synchronously by 2 rotations of synchronous pulley drive preformed screw rod, injecting motor 4 is cooperating the rollback of preformed screw rod 2 by above-mentioned injection driving-chain, finishes preformed.This injecting mechanism does not have guide post of the prior art, thereby can overcome that the physical dimension that prior art exists is big, the defective of bad dynamic performance, thereby reaches simple in structure, motion is steady etc. purpose.
