Definitions
- the invention concerns the processes and machinery used in making what are known as "preformers" of thermoplastic material for the production of blown receptacles.
- the first comprises an injection press and the injection die
- the second comprises a heater of the preformer, a blower and dies for blowing.
- An opening stroke of the injection die of not less than two lengths of the preformer make it necessary to have injection presses with a longer opening stroke, or which in any case are oversized.
- Subject of the invention is a process for molding the preformer in an injection press, or in installations comprising such a press, and with a blower, for the production of blown receptacles.
- the part of the injection die that must move on opening comprises two or more elements which, when the die opens, can translate radially in relation to the axis of the preformer.
- the preformer presents all the thicknesses for producing all the shapes obtainable by blowing and permitted by the presence of the translating elements.
- the opening stroke of the die is reduced to a length only slightly greater than that of the preformer.
- the preformer can present:
- the mobile parts of the die are constructed of aeronautical aluminium alloys or of other light alloys.
- the invention clearly offers the following advantages.
- the preformers the possibility of having preformers with outer walls of the following shapes:
- the injection press the possibility of drastically reducing the opening stroke of the die for extracting the preformer and therefore of being able to use a standard press instead of one with a longer opening stroke or one that is oversized.
- the injection die the possibility of reducing bulk and therefore the weight of the die by replacing parts in steel with others of an aluminium alloy.
- the economy of production benefits regarding speed of translation, less wear on the die and on the machine, and in operational economy by removal of shavings.
- the present invention therefore secures advantages regarding the preformer, and consequently the blown receptacle, by offering a greater variety of shapes both for functional and decorative purposes. These advantages are felt both when the preformers are made using an injection die in an injection press, and when a single installation is used for production of the preformer by injection and formation of the receptacle by blowing.

- Fig.19 A side view of the preformer in Figure 18.
- Fig.20 A longitudinal section of the preformer in Figure 18.
- Fig,.21 A preformer made by the process subject of the invention inside a blowing die to produce the shape of the blown receptacle, a longitudinal section.
- One half of a die 10 of the usual type presents the impression 11 with its bottom 12 and flange 13 fixed by screws 15 on the die, for injection molding of a preformer 20 with a lined surface 21 and semispherical bottom 22.
- a preformer 20 On opening the die extraction of the preformer 20 is eased by the lined surface 21 slightly conic in the direction of extraction and by the absence of undercutting.
- Figure 4 shows the die 40 subject of the invention.
- the two halves 41 and 42 of the die can be seen, these being mobile in relation to the structure 30 and guided by the bars 43 of the half die 41 that slide into holes 44 in the half die 42.
- the die impression comprises two half impressions 50 and 55 respectively provided with flanges 51 and 56 fixed by screws 57, and the male 58 with its end 59.
- the preformer 60 presents a semicylindrical body with lined surface 61 and the top 63 with its annular projections 64, raised band 65, raised annular rim 66.
- Wall thickness is generally variable (Figure 6); this in order to give greater thickness where, during blowing, the material undergoes a stronger radial and circumferential pull, and where it is desired to give greater thickness to the blown receptacle.
- the different wall thicknesses 66, 67, 69 are obtained by a male 70 having parts 72-74 of different diameters that increase from the bottom 71 to the top ( Figure 7).
- the stroke (A) made by the mobile die half 81 in relation to the base 82 is slightly greater than the length (B) of the preformer 60 due to radial movement, in the direction opposite to the preformer's axis XX, of the mobile parts 83, 84 of the die.
- Figures 9-11 show a preformer 90 with radial projections 91-93 of differing diameters, the top 94 having an upper ring 95, band 96 and rim 97 made by undercutting.
- Figures 12-14 show a proformer 100 which, compared with the previous one, presents longitudinal ribs 105 on a wall 106 of constant thickness.
- Figures 15-17 present a preformer 100 with annular ribbing, continuous 112 and set at intervals 113, on a wall 111 of constant thickness.
- Figures 18-20 illustrate a preformer 120 having a wall 121 of constant thickness, and having handles made by undercutting 122 at the top.
- Figure 21 is a diagram to show formation of a receptacle 135 by blowing a preformer 130 having undercutting at the top 131-133 produced by the die 40, subject of the invention, inside a mold 140.
