Abstract
A method for manufacturing plastic bottles with injection moulding machine is disclosed. A hole is made on the bottom plate of static mould, which is communicated with both the moulding cavity of static mould and the gas pipe of air compressor. The air valve and return spring are installed in the hole. The heating element on the external surface of static mould can maintain the temp of mould in a certain range. The pressure on demoulding is 0.5-1.2 MPa. Its advantages are simple operation, more than 500ml of volume for plastic bottles, uniform bottle wall, high quality of bottle and low cost.
Description
The present invention relates to a kind of manufacturing process and device that is in plastic state substance, particularly a kind of with producing injection and blowing bottle parison with injection machine method and be used for the mould of this method.
Along with China's science and technology development, the packaging industry of outward appearance is also progressive to some extent, as food, medicine .... the packing that waits, majority changes plastic bottle into by vial.At present, advanced employing is annotated the method for blowing and is produced plastic bottle, and the price of its equipment is very expensive, millions of yuans one of many person, and few person is also more than 800,000 yuan.It is reported, produce the machine of capacity 500ml die cavity plastic bottle, domestic one from West Germany's import, and can only produce square vase.
At present all use the hollow molding method to come the plastic bottle of production capacity greater than the 500ml die cavity, the deficiency point of its technology is: hollow is hung base because the weight of himself can be elongated, operating personnel operate with feel, the result is that the plastic bottle blank became uneven is even, the bottom bondingly is prone to breach, flies skin, overlap, and this bottle base is made bottle and also will be processed by hand.500ml, the 1000ml plastic bottle that market finding hollow molding method is produced is of poor quality, the bottle wall thickness is inhomogeneous, soft or hard does not wait, have in addition with just distortion of hand.As the packaging plastic bottle of the U.S. " Me Cog. " Alaska Salmon Oil100 softgels 275cc, also be hollow molding, at the obviously visible viscose glue vestige in the bottom seam place of bottle, illustrate that its seam quality is also poor.Owing to repair overlap, the bottleneck thickness is also extremely inhomogeneous.Existing method with producing injection and blowing bottle parison with injection machine must the demoulding behind the bottle base cooling and shaping, but the bottle base after the demoulding of finalizing the design just can't be blow molded into bottle again, if this bottle base is blow molded into bottle, unless carry out post bake.If the demoulding in bottle base can the temperature range of blowing, because the soft prepattern of bottle base will draw it bad by existing way.
The purpose of this invention is to provide a kind of with producing injection and blowing bottle parison with injection machine method and be used for the device of this method, particularly provide a kind of and produce the method for the injecting blowing plastic bottle base of capacity more than 500ml and be used for the mould of this method with injection machine.
The technical solution adopted in the present invention is:
During stripping process in matched moulds, injection moulding, stripping process, adopt compressed-air ejection.Compressed-air actuated pressure limit is 0.5-1.2Mpa, and the temperature range of mould is 80-100 ℃.
The mould that is used for this method is:
By dynamic model, quiet mould and core bar construction, on the base plate of quiet mould, have the hole that communicates with quiet model cavity bottom, the hole communicates with the air compressor machine snorkel, and air pressure valve and return spring are installed in the hole.Return spring is contained on the air pressure valve, on the outer surface of quiet mould heating element heater is installed.
When the injection moulding bottle base, by return spring air pressure valve is closed, air compressor machine is sent into compressed air during the demoulding, makes valve opening, releases the core rod and annotates blowing bottle parison, makes and annotates the blowing bottle parison demoulding.In the whole operation process, electrical heating elements makes the temperature of mould remain at 80-100 ℃ of scope, so just obtains being directly used in the plastic bottle blank of blowing.
The invention has the advantages that: 1, only need on the base plate of quiet mould, to have the hole that communicates with quiet model cavity bottom, the hole communicates with the air compressor machine snorkel, and air pressure valve and return spring are installed in the hole, just can be in stripping process, use compressed-air ejection, processing and operation are all simple and easy to do; 2, because plastic bottle blank is high temperature one-shot forming pack, need not manually scrape deburring, thus health, clean, pollute few; 3, the bottle base with the demoulding of the present invention can be blow molded into bottle immediately, does not need post bake, and the bottle wall thickness is even, and no waste material, no secondary turn one's head to expect, has not only guaranteed the quality of product but also has greatly reduced the cost of product; 4, adopt the present invention to produce various injecting blowing plastic bottle bases, be not only invention both domestic and external, and provide a fabulous technical scheme for injection machine enlarges the new scope of application with injection machine.
The present invention is further elaborated below in conjunction with description of drawings and embodiment.
Fig. 1 is a die profile of the present invention.
Wherein: 1, quiet mould; 2, dynamic model; 3, quiet baffle plate; 4, bottom the quiet model cavity; 5, hole; 6, air pressure valve; 7, return spring; 8, hole; 9, core rod; 10, annotate blowing bottle parison; 11, Electrothermal ring.
The embodiment of the invention 1:
During stripping process in matched moulds, injection moulding, stripping process, adopt compressed-air ejection.Compressed-air actuated pressure is 0.5Mpa, and the temperature of mould is 80 ℃.
The embodiment of the invention 2:
During stripping process in matched moulds, injection moulding, stripping process, adopt compressed-air ejection.Compressed-air actuated pressure is 0.8Mpa, and the temperature of mould is 85 ℃.
The embodiment of the invention 3:
During stripping process in matched moulds, injection moulding, stripping process, adopt compressed-air ejection.Compressed-air actuated pressure is 1.2Mpa, and the temperature of mould is 100 ℃.
The embodiment of the invention 4:
The mould that is used for this method is:
Constitute by dynamic model 2, quiet mould 1 and core rod 9, on quiet baffle plate 3, have and quiet model cavity 4 holes that communicate 5, bottom and hole 8, hole 8 communicates with the air compressor machine snorkel, air pressure valve 6 and return spring 7 are installed in hole 5, return spring 7 is contained on the air pressure valve 6, on quiet mould 1 outer surface Electrothermal ring 11 is installed.
When the injection moulding bottle base, by return spring 7 air pressure valve 6 is closed, during the demoulding, air compressor machine is sent into 0.8Mpa compressed air by air duct, and air pressure valve 6 is opened, and releases core rod 9 and annotates blowing bottle parison 10, makes and annotates blowing bottle parison 10 demouldings.In the whole operation process, Electrothermal ring 11 makes the temperature of mould remain at 80 ℃, so just obtains being directly used in the plastic bottle blank 10 of blowing.
