Description
Technical field
The present invention relates to injection molding technology, specifically a kind of multi-functional injection machine.
Background technology
Common injection machine is made up of injection moulding part, mold closing mechanism, hydraulic system, electric heating system and automatic control linked system, and major function is processed the plastic products injection mo(u)lding.Bigger for some volumes, the parts that the injection moulding difficulty is big need the long period to carry out at the machine curing molding.Generally want tens seconds at least, even one, two minute time, thereby production efficiency is low, has increased processing cost.Yet, for many colors of parts moulding with need the time to solidify the special process requirement of moulding standby die sinking, adopt legacy equipment to realize, that is: traditional injection machine can not satisfy the specific (special) requirements of new technology new product.
Summary of the invention
The purpose of this invention is to provide a kind of multi-functional injection machine that can adapt to multiple different process requirement.
To achieve these goals, technical scheme of the present invention is: comprise workbench, injection moulding part, mold closing mechanism, hydraulic system, it is characterized in that: workbench be rotary, have the multi-mould station, link to each other with motor through transmission mechanism, partly match with injection moulding; Described mold closing mechanism is from protective voltage type high-voltage lock mould structure, constitute by guide pin bushing, knockout rod, guide rod, cope match-plate pattern, lower bolster, guide rod is upper and lower two-layer, structure be arranged in parallel, two every layer, every guide rod one end is installed together with the injection molding plates in the injecting head the place ahead that is positioned at the injection moulding part, and the other end passes the guide pin bushing and the base plate that are installed on the rotary workbench and is connected, base plate is located on the rotary workbench, and piston is connected in the high-voltage oil cylinder of knockout rod and hydraulic system; Cope match-plate pattern and injection molding plates are installed together, and lower bolster and workbench are installed together; Hydraulic system comprises supercharger, high-voltage oil cylinder as the hydraulic power supply of supply high-voltage lock mould, and supercharger is installed in rotary workbench centre, communicates with high-voltage oil cylinder on being installed in each mould station by pipeline road.
Wherein: described cope match-plate pattern is provided with one or more injecting holes; Described injection mold station number can be 2～16; Unlike material raw material, material can place respectively in the hopper of a plurality of injection mold stations simultaneously; Can be used for installing the not injecting head of color of the same race, number is 2～16; High-voltage oil cylinder is identical with the number of injection mold; Described transmission mechanism can be worm gear, worm screw, or adopts gear drive, cycloid transmission, Gear Planet Transmission or infinitely variable speeds drive mechanism.
The present invention compared with prior art has more following advantage:
1. the present invention is to traditional injection moulding machine structure reform, can a tractor serves several purposes, can adapt to the special process requirement, and make the plastic part grade produce qualitative leap.Adopt the present invention can realize the composite molding injection moulding, as: 1) successively several plastic materials of different nature are injection-moulded in together, to change the mechanical performance and corrosion-resistant, the anti-wear performance of moulding; 2) reach special art designing's requirement that the moulding diverse location has different colours, carry out monochromatic injection moulding, multiple color, the injection moulding of injection moulding flower texture; 3) realize standby die sinking, that is: the continuous injection moulding of injection moulding station.
2. adopt the present invention can realize high efficiency, low cost.Described mould can further be controlled by circuit, change over to down earlier station treat parts solidify after die sinking again, and then increased exponentially productivity ratio, reduced the injection moulding cost.For example: some plastic products partly needs wear-resisting (bearing portions and guide rail pivoted housing, slide plate, sliding sleeve), but whole plastic body does not need whole wear-resistant materials, and the technology of this parts part material modification just can realize in the present invention; Also have some workers to mould goods a part and need heatproof, need to annotate temperature-resistant materials such as poly-tetrafluoro, this then can not realize on common injection machine, the present invention but can conveniently be integrated by the material that multiple attribute is different, become a kind of efficient synthesizer that specific function is arranged, thereby the present invention is the new concept to the engineering plastics processing technology, taking the lead a step aspect the change of injection machine technology.
