Description
Technical field
The present invention relates to blow moulding machine technical fields, and in particular to a kind of for producing the blow moulding machine and its work of cubic container
Make method.
Background technique
Blow molding is also referred to as hollow blow molding, is current plastic processing a kind of commonly method.Thermoplastic material is by push base
The mechanism of material squeezes to obtain hollow plastic parison, takes advantage of it and is heated to soft state, is put into molding die, close mold it
It is passed through air inside backward parison, parison is expanded and is tightly attached to it on mould inner surface, after parison is cooling from mold
It takes out, product to be processed can be obtained.Blow molding is extremely common method in plastic processing production, and blow molding process is given birth to
The product of production is mainly container.
The present age is derived from for the forming technique of plastic products processing in the 1930s, still equipment at that time is with glass
Glass is that raw material carries out blow molding processing.Because the cost of plastics is very high at that time and processing performance is poor, lead to the synthesis of plastic bottle
Advantage is far away from vial, to seriously hinder the development of plastic blow molding.But with being widely used for polyethylene,
Plastic blow molding technology has also obtained wide development space.Because the anti-extrusion that there is polyethylene glass not have is excellent
Point, and plastics have the advantages that light weight, non-breakable.Hereafter, there is the continuous blow moulding machine for squeezing out function, which to be developed, makes
Plastic blow molding technology is further developed.Though blow molding technology also can be used for mainly for the production of container and packaging
Processing industry part, this also makes blow molding technology have higher value for applications.It is shown by investigation, existing at present
Having 80%~90% in hollow container is produced by blow moulding machine.And relative to current packaging market, plastics package and paper
Matter packaging is occupied an leading position.But with the implementation of Environment Protection Policy and energy saving policy, the market of papery packaging is occupied
Rate has gradually decreased, and plastics package has the characteristics that the durable favor for obtaining more multiple enterprises because of it.
With the development of hollow blow molding technology and the promotion of blow moulding machine performance, quality of the social and enterprise to blow molded product
And processing performance also proposed increasingly higher demands.And the quality of product is improved, stringent control is carried out to the wall thickness of parison
System is a kind of particularly important mode.Since the forming process of parison is hung at mouth mold, so being influenced by its self weight
Non-uniform contraction can be generated and stretch phenomenon, it is even so as to cause the wall unevenness of parison；Meanwhile even if ignoring parison self weight
Influence is regarded as the identical blank of wall thickness everywhere, because parison is very different in the blow-up ratio of mold everywhere, this also can
Cause the product wall unevenness produced even.
