Abstract

The utility model relates to a blow moulding machine, which solves the problems of increasing the rate of finished products and the production efficiency. The utility model discloses a large container injecting, drawing and blowing two-step blow moulding machine, comprising an injection machine, a bottle blowing machine, a parison heater, a parison mould, a cooling device, a power source, an air source, and the devices of the power source and the air source. The blow moulding machine comprises an organism, a guide column, a mould plate and a mould. The utility model is characterized in that the upper part of a machine body is provided with a cylinder, and the cylinder is provided with a stretching rod. The lower end of the stretching rod is provided with a connecting element. A heating rod and a thermocouple which controls the heating rod are arranged in the mould, and a heating medium and the hole passage of the heating medium are arranged in the mould. The utility model is used for manufacturing large containers.

Description

Bulk container is annotated stretch blow two-step method blow moulding machine

The utility model relates to the container blow moulding equipment, especially refers to 5 gallons of transparent drum blow moulding equipments such as mineral water.

Existing general plastics bulk container blowing adopts extrusion blow and notes to blow, and its equipment manufacturing cost height, productivity ratio is low, leftover bits are many; But and annotate the stretch blow two-step method because the centralized production bottle base, and then make bulk container, equipment letter, productivity ratio height, cost are low.But more than the bottle base wall thickness 5mm, because shrinkage factor is big, the moulding inaccuracy, and cooling is slow, influences the production cycle and because heating is inhomogeneous, makes yield rate not high enough.

The purpose of this utility model provides a kind of production equipment, and tube, the preferable bulk container of efficient yield rate are annotated stretch blow two-step method blow moulding machine.

The purpose of this utility model is achieved in that bulk container notes stretch blow two-step method blow moulding machine, and it comprises injector, bottle blowing machine, parison heater, parison mould and cooling device and power source, air source and device thereof; And blow moulding machine contains organism, guide pillar, template, mould, it is characterized in that: body upper is provided with cylinder, and cylinder has the stretching bar, and there is connecting piece stretching bar lower end; Be provided with the thermocouple of heating rod and control heating rod in the mould, and be provided with heat medium and duct thereof.

Injector, bottle blowing machine, cooling device and power source, air source and device thereof etc. all adopt prior art with high-frequency heating for above-mentioned design, parison, and picture and text are omitted.Because make thermal source with the high-frequency heating rod, and thermocouple control is arranged, and heat medium has many ducts in the mould, adds high-frequency heating, homogeneous heating can blow out bulk container smoothly, has reached the effect that obtains preferable yield rate and productivity ratio with simpler equipment.

Below by drawings and Examples the utility model is described further again.

Fig. 1 is the utility model blow moulding machine structural representation;

Fig. 2 is the utility model heating generator structural representation.

As shown in Figure 1: the utility model blow moulding machine is made up of body 10, guide pillar 4, template 5 and mould 8 etc., and cylinder 1 is arranged at body 10 tops, and cylinder 1 has stretching bar 2, and there is connecting piece 3 stretching bar 2 lower ends; Many heating ducts 7 are arranged in the mould 8, make thermal source by heating rod 9, and controlled by thermocouple 6.

As shown in Figure 2: heating generator of the present utility model is mainly used in heating wall thickness thicker parison, and it is made up of high frequency electric source 11 and electrode die 14, and high frequency electric source 11 has power supply control piece 12 and input, output line 13; Electrode die 14 is provided with two electrodes 16,17 and cooling

medium gateway

15,19; Have the cylinder 21 of piston rod 20 as power, be contained on the electrode 17, electrode 17 can be moved up and down, and parison 18 is clipped between two electrodes 16,17.

Course of action of the present utility model is such: injecting preform at first, if parison requires thickening, can be again in another pair is touched the mould in chamber greatly injection moulding second layer parison, by that analogy; Thin parison can be used quartz lamp heater, thicker parison heating generator, its cooling medium constantly circulates through

medium gateway

15 and 19, the parison of finishing through heating promptly can be moved to the utility model blow moulding machine and carries out the processing of second step, behind the matched moulds, stretching bar 2 can stretch parison and inflation, and the heat medium in the mould is heated by electrical bar 9 and circulates by medium duct 7, pass through said process, a plastics bulk container, promptly processed successfully, this shows the determined injection moulding of heavy wall parison of Jie of the utility model success, cooling and blowing heating are with topic, yield rate height, quality is good, has transparency preferably, intensity, wearability and hear resistance, and can know the trade mark that reproduces mould, literal.
