Description
Technical field
The present invention relates to blow moulding machine technical field, and in particular to a kind of blow moulding machine and its work for being used to produce cubic container
Make method.
Background technology
Blowing is also referred to as hollow blow molding, is a kind of conventional method of current plastic processing.Thermoplastic is by push base
The mechanism of material extrudes to obtain hollow plastic parison, takes advantage of it and is heated to soft state, is put into mould, close mould it
Air is passed through inside backward parison, parison is expanded and it is close on mould inner surface, after parison cooling from mould
Take out, you can obtain product to be processed.Blowing is method extremely conventional in plastic processing production, and blow molding process is given birth to
The product of production is mainly container.
The forming technique that the present age is used for plastic products processing is derived from the 1930s, still equipment at that time is with glass
Glass is that raw material carries out being blow molded processing.Because the cost of plastics is very high at that time and processing performance is poor, cause the synthesis of plastic bottle
Advantage is far away from vial, so as to seriously hinder the development of plastic blow molding.But with widely using for polyethylene,
Plastic blow molding technology has also obtained wide development space.Because polyethylene has the excellent of the anti-extrusion that glass do not have
Point, and plastics have the advantages of light weight, non-breakable.Hereafter, there is the blow moulding machine of continuous extrusion 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.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 saving energy policy, the market share of papery packaging
Rate gradually reduces, and plastics package has the favor that the characteristics of durable in use obtains more multiple enterprises because of it.
With the development of hollow blow molding technology and the lifting of blow moulding machine performance, quality of the social and enterprise to blow molded product
And processing performance it is also proposed higher and higher requirement.And the quality of product is improved, strict control is carried out to the wall thickness of parison
System is a kind of particularly important mode.Because the forming process of parison is hung at mouth mold, so being influenceed by its deadweight
Uneven contraction and stretching phenomenon can be produced, so as to cause the wall unevenness of parison even；Meanwhile even if ignore parison deadweight
Influence is regarded as wall thickness identical blank everywhere, because blow-up ratio of the parison in mould everywhere is very different, this also can
Cause the product wall unevenness produced even.
