Description

Injection machine remodeling integral seat and injection cylinder

Technical field

The utility model relates to injection machine, particularly relates to the integral seat and the injection cylinder of injection machine.

Background technology

Mould and matched moulds assembly are installed on one of the injection machine support, and injection moulding assembly and oil motor are installed in the other end, the major part of injection moulding assembly is integral seat and the barrel that is connected integral seat, and injection cylinder.The prior art integral seat is whole linking to each other with injection cylinder, because barrel constantly heats plastic raw materials at work, so the heat part of barrel passes to integral seat, after being heated, integral seat directly influences injection cylinder again, injection cylinder is brought heat into fuel tank by oily medium in the course of the work, thereby the temperature of injection oil constantly savings increases, and the sealing ring of injection cylinder, hydraulic valve are damaged easily owing to be subjected to temperatures involved, and is especially even more serious in summer.Because injection cylinder is whole linking to each other with integral seat, so installation, dismounting, the maintenance of part are pretty troublesome in processing and the cylinder, change sealing ring needs the long period at every turn, has directly influenced the normal production time, inefficiency again.On the other hand, barrel causes barrel not high near the temperature liter of integral seat part because injection cylinder is constantly taken away heat, has directly influenced the heating of barrel to plastic raw materials, causes power consumption to increase.Injection machine still has thermoplastic materials and flows out when barrel exports after injection moulding, is called the hydrostomia plastics, in pre-plastic process, negative pressure is arranged in the barrel, and prior art produces negative pressure after injection moulding, and anti-hydrostomia speed is slow.

Summary of the invention

The utility model is in order to overcome the defective of existing injection machine integral seat and injection cylinder structural relation, provide a kind of injection cylinder not to be subjected to the barrel temperatures involved, improve accessory service life, accessory is installed, dismantles laborsaving in injection cylinder processing and the cylinder, and make the barrel thermal loss few, save the injection machine remodeling integral seat and the injection cylinder of energy consumption.

The technical scheme of the utility model injection machine remodeling integral seat and injection cylinder is: be installed in oil motor, integral seat on the support, hopper is arranged on the integral seat, integral seat connects barrel, oil motor is shaped on the support ear, the both sides that it is characterized in that integral seat are shaped on the connection ear, connect in the ear injection cylinder is installed, the piston rod of injection cylinder penetrates in the oil motor support ear piston hole.Its described injection cylinder is unidirectional injection cylinder, and the end of injection cylinder connects unidirectional anti-hydrostomia oil cylinder, and the anti-hydrostomia piston rod in the anti-hydrostomia oil cylinder is connected with unidirectional injection ram.Integral seat be connected between the ear gapped.The technical program one is that injection cylinder is installed on the connection ear of integral seat, injection cylinder and integral seat contact portion are greatly reduced, reach separation degree, overcome from the influence of the heat of barrel injection cylinder, avoid oil to penetrate sealing ring in the oil cylinder, hydraulic valve etc. and be subjected to high temperature and damage, guarantee ordinary production, reduce maintenance, increase work efficiency, and injection cylinder is easy to manufacture.The 2nd, the injection oil of injection cylinder is not taken away the heat from barrel, makes the heating of barrel keep stable, and especially barrel is few in the portion temperature loss near integral seat, has obvious energy-saving effect.The 3rd, injection cylinder can be a two-way cylinder, it also can be unidirectional injection cylinder, if unidirectional injection cylinder, speed is fast, particularly unidirectional anti-hydrostomia oil cylinder and unidirectional injection cylinder are in series, make barrel injection back produce certain vacuum and prevent that immediately thermoplastic materials from flowing out, unidirectional resistance is little, anti-hydrostomia is rapid, reliable for effect.The dismounting that improves unidirectional injection cylinder in back and unidirectional anti-hydrostomia oil cylinder is easy, maintain very convenient, laborsaving, raising machinery utilization rate and operating efficiency.

The specific embodiment

The utility model discloses a kind of is to the improvement of injection machine integral seat and injection cylinder design, relate to the oil motor 3 that is installed on the injection machine support 1 (or by guide rod 2), integral seat 7, hopper 8 is arranged on the integral seat 7, integral seat connects barrel 12, oil motor is shaped on support ear 4, it mainly improves design and is that the both sides of integral seat 7 are shaped on connection ear 6, as shown in Figure 3, connect injection cylinder 9 is installed in the ear 6, as shown in Figure 2, owing on oil motor 3, be shaped on support ear 4, as Fig. 2, shown in Figure 4, support ear 4 is shaped on piston hole, and the piston rod 5 of injection cylinder 9 is penetrated in the piston hole of oil motor support ear 4.The heat of barrel 12 (plastics add hot flow path) is no longer passed to injection cylinder after passing to integral seat like this, make the oil temperature that flows in injection cylinder and the fuel tank with low uncertainty, do not influence service lifes such as seal and valve, the barrel heat is reduced the loss, obvious energy conservation, the injection moulding quality assurance, the processing of injection cylinder simultaneously is very laborsaving, installs and keep in repair, maintains very convenient.In order to make the anti-hydrostomia resistance of barrel few, speed is fast, reliable for effect, injection cylinder can be made unidirectional injection cylinder 9, connect unidirectional anti-hydrostomia oil cylinder 10 in the end of unidirectional injection cylinder 9, and the anti-hydrostomia piston rod 11 in the unidirectional anti-hydrostomia oil cylinder 10 and unidirectional injection ram 5 ' be connected, become series connection.In order to make heat that injection cylinder is subjected to integral seat still less, can be shaped on gap 13 between the ear 6 with being connected at integral seat 7, mutually between small part connect, and major part separates.
