Moulds are necessary for injection moulding, but as product shapes become more complex, various mechanisms are incorporated. It is no exaggeration to say that a mould is a mass of a company's know-how.
This month's article introduces one type of know-how: slide moulds.
In general, the product shape is carved into the cavi-core of the mould, into which the resin is poured.
The cavi-core can only be opened and closed in one direction, so the product shape must take this into account.
However, if you really want to incorporate additional shapes, you can incorporate a slide mechanism in the mould to
This avoids the need for undercuts.
While a slide mechanism allows for greater flexibility in product shape, it also increases the frequency of maintenance, as the mould is larger and has more operating space. This must be taken into account when designing products.
In the past, we have mass production experience with moulds with 1 CaviSlide and 4 CoreSlide mechanisms.
As this product had deep ribs, a nest with a gas venting structure and three-dimensional piping modelled on a 3D printer was incorporated.
We understand the advantages and disadvantages of slide moulds and can offer mass production of complex shapes.
