Abstract
The utility model relates to a device for forming plastic, particularly a mould for producing an injection blow-molding plastic bottle parison with more than 500 ml by using an injection molding machine. The utility model is characterized in that holes are arranged on a bottom board of a static mould, and the utility model is provided with a pneumatic valve and a reset spring communicated with an air pipe of an air compressor. The outer surface of the static mould is provided with a heating element, and demoulding can be realized by the compressed air during injection phase; the demoulded mould is carried out with injection blow-molding bottle parison without secondary heating, and the injection blow-molding bottle parison can be directly formed on the injection molding machine.
Description
The utility model relates to a kind of plastics forming device, particularly a kind of mould with producing injection and blowing bottle parison with injection machine.
In the existing plastic products processing, produce plastic bottle and substantially all use the hollow molding method, and the container in large capacity version chamber can only adopt the hollow molding method.Hollow is hung base because the weight of himself can be elongated, and operating personnel operate with feel, and the result is that the plastic bottle blank wall thickness is inhomogeneous, and skin, overlap appear flying in the easy breach in bonding place, must process by hand at last.Therefore, plastic bottle of poor quality easily polluted, and be not only unhygienic but also unclean.Annotate, blow two-step method production equipment complex structure, installation, maintenance difficulty height, fetch long price.Use 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, just must carry out post bake.If bottle base can blowing temperature with the bottle base demoulding, can carry out blowing, but demoulding this moment bottle base prepattern is again pressed the usual practice existing mold demoulding, will draw it bad.
The purpose of this utility model provides a kind of mould with producing injection and blowing bottle parison with injection machine, and a kind of mould of producing the injecting blowing plastic bottle base of capacity more than 500ml with injection machine particularly is provided.
Mould of the present utility model 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, 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 remains at the temperature of mould and guarantees to make the blow moldable temperature range of plastic bottle blank, so just obtain being directly used in the plastic bottle blank of blowing.。
Advantage of the present utility model is: 1, mould structure is simple, makes, operates, keeps in repair simple and easy to do; But 2, annotate blowing bottle parison in blow temperatures demoulding on injection machine, do not need post bake, can be blow molded into bottle on blow moulding machine, 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; 3, adopt mould of the present utility model, available injection machine is produced various injecting blowing plastic bottle bases, has enlarged the scope of application of injection machine.
Below in conjunction with description of drawings and embodiment the utility model is further elaborated.
Fig. 1 be the utility model proposes with the mould of producing injection and blowing bottle parison with injection machine cutaway view at injection moulding matched moulds state.
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.
Embodiment 1:
Mould of the present utility model is made of 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 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 remains at the temperature of mould and guarantees plastic bottle blank 10 blow moldable temperature ranges, so just obtains being directly used in the plastic bottle blank 10 of blowing.
Claims (2)
1, a kind of mould with producing injection and blowing bottle parison with injection machine is made of quiet mould 1, dynamic model 2 and core rod 9, it is characterized in that:
1. have hole 5 and hole 8 on the quiet baffle plate 3, hole 5 communicates with quiet model cavity bottom 4, and hole 8 communicates with the air compressor machine snorkel,
2. on the air pressure valve of in hole 5, installing 6 return spring 7 is housed,
On the outer surface of 3. quiet mould 1 heating element heater is arranged.
2, the mould with producing injection and blowing bottle parison with injection machine according to claim 1 is characterized in that:
Heating element heater on quiet mould 1 outer surface is an Electrothermal ring 11.
