Mould sets for blow moulding machines

This invention relates to mould sets for use in blow moulding machines including blow molding machine and moulding machines which are intended for prototype or other short run purposes. Mould sets are also known as mould bases.

Blow moulding machine has been known for many years and designs of such machines are available some of which are particularly suited to short run or prototype manufacture. Hitherto, the mould sets for all types of injection moulding machines have been made mainly of high quality tool steel which is not only a costly material but requires expensive machining operations in order to achieve the required longevity in use. Such mould sets are acceptable from a cost standpoint for long production runs of blow articles which may reach very large figures. However, when the mould set is only required for comparatively short runs, sometimes very short indeed where prototypes are involved, the cost of the mould sets becomes an unacceptably high proportion of the cost of production of the prototype articles.

Further according to the present injection moulding machine there is provided a mould set for use in a plastic injection molding machine comprising at least one individual main component of constant, predetermined, cross-section of extruded, high duty, aluminum alloy.

By manufacturing the main components of a high duty aluminum alloy the amount of machining eventually required is small because features of the components which are conventionally machined can readily be incorporated in the section as extruded, and it is of course readily possible to provide subsequently to extrusion the bores and passages through the components which are transverse to the direction of extrusion of the component. The final finish can be effected by spark erosion techniques or other conventional machining. If desired water cooling holes extending in the direction of the extrusion motion may be provided during the extrusion process.

As will be understood by those skilled in the art any main component of a mould set can be produced such as a cavity plate or an ejection plate and sliders.

The invention is also applicable to mould set components for blow molding machine.

Blow molding machine in China

China is the world’s largest manufacturer of blow molding machine, ranking first in the world on both yield and consumption. Chinese blow moulding machine industry is mainly distributed in Guangdong, Jiangsu and Shandong provinces accounting for 88% of total enterprises in Chinese blow molding machine industry, as per a report by Research and Markets. Totally speaking, East China takes absolute advantages, of which enterprise quantity in Zhejiang province accounts for 61%, having increased by 14 enterprises over that in 2005. In 2000, market capacity of the whole industry realized RMB 4.598 bln, increasing to RMB 14.578 bln in 2006. Following it, per capita sales revenues have been increasing year after year, from RMB 198,114 in 2000 to RMB 462,012 in 2006 up by three times. Totally speaking, the market still kept a stable growth and gross profit margin is in decline; while profits are rapidly climbing. Undoubtedly, all of these have showed that China injection Molding Machine Industry has been in a growing period.
In the past few years, blow molding machine manufacturing and technology companies has been greatly improved technology and management. However, compared with developed countries, China still needs to make up for plastic injection molding machine technology and varieties. In detail, there is still not little blank on such varieties as super-large or special precision blow molding machines; meanwhile, self-support rate of home-made blow molding machines for products processing is only about 45%; while for high-end products processing, most adopt imported blow molding machines. Totally speaking, research and manufacturing of blow molding machines cannot still satisfy demands brought by development of plastics industry in China.
As for industrial machinery, other machinery processing enterprises now most have been very little interest, and only the rapid development of blow molding machine. And with sustaining and promising market, many enterprises which originally produced machine tools, textile machinery and power equipments, also started to produce blow molding machines. At the same time, the newly established manufacturer of blow molding machines is growing rapidly, therefore, primarily in common blow molding machines and the discount price war war
