Description
Technical field
The present invention relates to Plastic Rolling Molds technical field is and in particular to one kind can shorten the production time, reduce production cost, security performance height, can energy efficient, the automatic fast demoulding mold closing mechanism of the Plastic Rolling Molds of raising plastic parts product quality.
Background technology
Rotational moulding, also known as rotation molding, rotational forming, rotation-formed etc., is a kind of thermoplastic hollow forming method.The method is first to add in mould by plastic raw materialss, then mould constantly rotates along two vertical axises and is allowed to heat, plastic raw materialss in mould are in the presence of gravity and heat energy, gradually equably coating, melting adhere in the whole surface of die cavity, it is shaped to required shape, more cooled sizing forms product.
The basic course of processing of rotation molding is very simple: be exactly powder or liquid polymer be placed in mould heat simultaneously mould around two vertical axises rotation and revolution, then forced ventilation or water-spraying control are passed through, then it is placed on working area, here, mould is opened, the product completing is removed, then carries out next round circulation again.
When rotational molding method is obtained plastic parts, it compares other forming methods such as blowing, injection etc., haves the advantages that very big: its mould is simple, with low cost, can dispose various inserts, the shape of rotational moulding product can be extremely complex.Therefore, rotation molding is applied in productive life more and more.
But, in prior art, rotation molding there is also a lot of shortcomings and need to improve.Because in the rotational moulding product course of processing, Plastic Rolling Molds needing to open, separating to take out plastic, or close up, close to add plastic raw materialss.Mould opens, separate, the referred to as demoulding, conversely, mold clamp, closing, referred to as matched moulds.
The structure of Plastic Rolling Molds is generally made up of multi-piece die around, every die is needed all to unload one by one after formed product during the demoulding, in prior art, it is all using the artificial demoulding during the usual demoulding, so there is ambiguity to the operating time and prescription of employee, there is certain hidden danger in stripping means simultaneously, for example: mould is easily damaged, product is easily damaged, demoulding time long, contractibility control is not accurate etc., and the temperature of mould is higher, there is certain scald hidden danger to operator.During matched moulds, continue to use traditional craft always and position, close up, close, this clamping system needs operator to use the aids such as iron rod, screwdriver, hammer drill, by force the corresponding screw hole of the separate section of mould is aligned, to insert screw, to tighten, make mold clamp, close, be i.e. matched moulds.Manual matched moulds high labor intensive, positioning inaccurate, easy damaged mould, low production efficiency.
In a word, in prior art, the demoulding matched moulds process mechanism of Plastic Rolling Molds, automaticity are low, and its plastic parts production cost height, long the production cycle, high energy consumption, product quality are low.
