Description

15 20 25 -30 35 459 798 Detta uppnås enligt uppfinningen genom att en materialsats bestående av en flytande plastblandning med fibrer först an- bringas på en yta på ett stödelement. vars form är komple- mentär med fornytan på nämnda formhalva. att fornelementet med formytan nedàtvånd placeras över materialsatsen och att stöd- elementet och fornnalvan vândes tillsammans. så att fornhalvan ' hamnar under naterialsatsen. varefter stödelenentet avlägsnas. vid ett sådant förfarande sprutas lämpligen laterialsatsen mot en folie, som är fastsugen not en perforerad suglada. Folien kan vara av sådant laterial son hâftar fast vid naterialsatsen och tillåts då sitta kvar på den slutliga produkten. Alterna- tivt kan den vara preparerad eller bestå av sådant laterial. att den lätt kan rivas loss. This is achieved according to the invention by first applying a set of material consisting of a liquid plastic mixture with fibers to a surface of a support element. whose shape is complementary to the advantage of the said half of the shape. that the antique element with the mold surface facing down is placed over the material set and that the support element and the antique needle are turned together. so that the ancient half 'ends up below the material charge. after which the support element is removed. in such a process, the lateral batch is suitably sprayed against a foil which is attached to a perforated suction cup. The foil can be of such a lateral son adheres to the material set and is then allowed to remain on the final product. Alternatively, it may be prepared or consist of such lateral. that it can be easily torn off.

Sättet enligt uppfinningen säkerställer fullständig övertäck- ning av en fornyta utan risk för att naterialsatsen förlorar form eller gär sönder.The method according to the invention ensures complete covering of an antifouling without risk of the material batch losing shape or breaking.

Uppfinningen beskrives nedan under hänvisning till bifogade figurer 1-6, son visar satsningsförloppet närnare.The invention is described below with reference to the attached figures 1-6, which show the investment process in more detail.

I figurerna l-4 betecknar 1 en suglâda ned perforeringar 2 och ett utlopp 3 avsett att anslutas till en fläkt. Suglâdan l är formad konplenentär ned ett fornrun eller fornhâlighet 4 i en fornnalva 5 till ett fornverktyg, avsett för fornpressning av komponenter av konpositnaterial. såsom glasfiberarnerade härd- plasten.In Figures 1-4, 1 denotes a suction box down perforations 2 and an outlet 3 intended to be connected to a fan. The suction box 1 is formed complementary down an ancient run or retaining cavity 4 in an ancient needle 5 to an ancient tool, intended for ancient pressing of components of composite material. such as fiberglass-cured thermosets.

När en naterialsats skall anbringas not fornrulnets 4 fornyta 6 är tillvägagângssâttet följande: En tunn folie 7 av plast placeras över suglâdan 1 och sugs fast vid denna. varefter fibrer och natrisnaterial 8 (flytande R plastblandning) sprutas över folien 7 ned en sprutalfiber- cutter 9 (fig. l). Fornnalvan 5 sänkes i upp- .och nedvånt läge ned över naterialsatsen (fig. 2). så att fornytan 6 slut- ligen vilar not materialsatsen. Hela arrangenanget. sugläda 1. a 459 798 formhalva 5 samt mellanliggande materíalsats vänds därefter. så att formhalvan 5 hamnar i rättvänt läge (fig. 3).When a set of materials is to be applied to the front surface 6 of the roll 4, the procedure is as follows: A thin plastic foil 7 is placed over the suction box 1 and sucked onto it. after which fibers and sodium material 8 (liquid R plastic mixture) are sprayed over the foil 7 down a syringe fiber cutter 9 (Fig. 1). The forearm 5 is lowered in the up and down position down over the batch of material (Fig. 2). so that the benefit 6 finally rests the note material set. The whole arrangement. suction slide 1. a 459 798 mold half 5 and intermediate material set are then turned. so that the mold half 5 ends up in the upright position (Fig. 3).

Suglâdan 1 lyftas nu undan (fíg. 4), varvid luft kan blâsas ut genom perforeríngen 2 för att underlätta operationen. En övre formhalva 10 sänks nu ned över formhalvap 5 (tig. 5) och pres- sar slutligen not naterlalsatsen för att konpaktera densamma.The suction box 1 is now lifted away (Fig. 4), whereby air can be blown out through the perforation 2 to facilitate the operation. An upper mold half 10 is now lowered over mold half apex (Fig. 5) and finally presses the note set to compact it.

När materialsatsen stelnat (härdat) säras fornhalvorna 4 och 10. varpå den färdiga detaljen lyfts ut.When the material set has solidified (hardened), the antique halves 4 and 10 are separated, after which the finished part is lifted out.
