The fine mini-centring unit 7980/1 from Agathon is for backlash-free centring of mould inserts for standard moulds used in injection moulds.
For the manufacture of injection moulds, interchangeable inserts are used in master moulds, which is often used for injection moulding variants. Thus the same family of parts is used for producing both differing and similar injection moulding parts. Very often, small series is produced (“just in time” production), resulting in the injection press undergoing frequent mould insert changes and the inserts need quick changing.
For such jobs to run smoothly and accurately, the fine mini-centring unit 7980/1 from Agathon is for backlash-free centring of mould inserts for standard moulds used in injection moulds. This centring is also for high-precision connections in the construction of machinery in mechanical engineering.
According to Agathon, the ability to use a bush-free assembly enables ultra-precision as errors in the concentricity of the guide bush are avoided and a positioning accuracy of less than 1µm is thus possible.
The company also offers ball guides and roller guides, backlash-free for high-performance injection moulds as well as for hybrid and cutting tools. The use of bearing guidance systems eliminates the need of a fine centring device or an additional fine centring system. The cage retention system proposed just for this combined with a compression spring depending on the application allows for the complete withdrawal of the preloaded bushing. Accurate cage positioning is therefore guaranteed when the two tool halves are reunited, Agathon claims. Apart from the company’s offerings provided in its standard catalogue, Agathon also manufactures special parts as per customer plans like rust-proof guide elements.
