Description
Izum se odnosi na kalup u dijelovima za proizvodnju staklenih predmeta. Takav kalup je većinom sastavljen od dva dijela. Svaka polovica kalupa pričvršćena je na držaču kalupa stroja za oblikovanje, da bi se kalup zatvarao i otvarao. Kod prešanog oblika se većinom kapljasto oblikovana gruda rastaljene staklene mase batićem utisne u šupljinu kalupa zatvorenog oblika. Nakon skrutnjavanja se držači kalupa razdvoje i iz kalupa se izvadi stakleni predmet. Kod puhanih oblika i podtlačenih oblika se postupa na sličan način, ali se tada plastičnu staklenu masu unosi u kalupe upuhivanjem ili usisavanjem. The invention relates to a mold in parts for the production of glass objects. Such a mold is usually composed of two parts. Each half of the mold is attached to the mold holder of the molding machine, to close and open the mold. In the case of pressed form, a mostly drop-shaped lump of molten glass mass is pressed into the cavity of a closed mold with a mallet. After solidification, the mold holders are separated and the glass object is removed from the mold. In the case of blown shapes and pressurized shapes, the procedure is similar, but then the plastic glass mass is introduced into the molds by blowing or vacuuming.
Kod poznatog kalupa polovice kalupa su npr. od legiranog čelika ili legiranog sfero-lijeva. Uslijed velike razlike u temperaturi između staklene taline u šupljini kalupa i temperature okoline, dolazi kod poznatog kalupa do vitoperenja polovica kalupa i time do zapune bridova kalupa, dakle bridova u razdjelnoj ravnini polovica kalupa na plohi koja je u dodiru sa staklom u šupljini kalupa. Uslijed ovog vitoperenja može se na staklenom predmetu oblikovati grubi, vidljivi šav. Oblikovanje šava se nadalje kod poznatog kalupa pojačava habanjem u području bridova kalupa. Kod poznatog kalupa ostaje također problem odvođenja topline iz šupljine s rastaljenom staklenom masom prema vani, što je suprotno skraćenju trajanja takta i time povećanja proizvodne brzine. In the case of a known mold, the mold halves are, for example, made of alloyed steel or alloyed spheroidal cast iron. Due to the large difference in temperature between the glass melt in the mold cavity and the ambient temperature, in the case of the known mold, the halves of the mold are blown and thus the edges of the mold are filled, that is, the edges in the dividing plane of the mold halves on the surface that is in contact with the glass in the mold cavity. As a result of this weathering, a rough, visible seam can form on the glass object. The shaping of the seam is further enhanced with the known mold by wear in the area of the edges of the mold. With the known mold, there is also the problem of heat removal from the cavity with the molten glass mass to the outside, which is the opposite of shortening the cycle time and thereby increasing the production speed.
Zadaća je izuma da se izradi kalup u dijelovima, kojim se velikom proizvodnom brzinom mogu proizvesti stakleni predmeti urednog šava. The task of the invention is to create a mold in parts, which can be used to produce glass objects with a neat seam at a high production speed.
To se prema izumu postiže kalupom u dijelovima naznačenim u zahtjevu 1. U podzahtjevima su dane preferirane izvedbe kalupa prema izumu. According to the invention, this is achieved with a mold in the parts indicated in claim 1. Preferred embodiments of the mold according to the invention are given in the subclaims.
Kalup prema izumu ima uložak, koji zatvara šupljinu kalupa, a oko uloška, plašt. On može biti konstruiran u dva ili više dijelova. Svaka polovica kalupa, odnosno svaki dio kalupa je pritom oblikovan od uložnog dijela i plaštenog dijela. The mold according to the invention has an insert, which closes the cavity of the mold, and around the insert, a mantle. It can be constructed in two or more parts. Each half of the mold, that is, each part of the mold, is formed from an insert part and a sheath part.
Plašt, odnosno plašteni dio, je od lakoobradivog materijala relativno dobre toplinske vodljivosti, npr. od nelegiranog čelika, kao građevnog čelika ili sivog lijeva. The sheath, or the sheathed part, is made of easily machined material with relatively good thermal conductivity, for example, unalloyed steel, construction steel or gray cast iron.
Uslijed dobre obradivosti mogu se primjerice u plaštu na dodirnoj plohi između plašta i uloška predvidjeti rashladni kanali. Po potrebi se kroz rashladne kanale također može propuhivati komprimirani zrak. Due to the good machinability, cooling channels can be provided, for example, in the jacket on the contact surface between the jacket and the insert. If necessary, compressed air can also be blown through the cooling channels.
Rashladni kanali se prvenstveno protežu do područja najvećeg toplinskog opterećenja kalupa. Ovo toplinsko opterećenje općenito nastaje u prostoru u kojem se prvenstveno nalazi rastaljena staklena masa, prije nego se ona batićem ili puhanjem ili usisavanjem raspodijeli šupljinom kalupa. Dodatno hlađenje je stoga, osobito u ovom prostoru, od značenja za povećanje proizvodne brzine. The cooling channels primarily extend to the area of the highest heat load of the mold. This heat load generally occurs in the space where the molten glass mass is primarily located, before it is distributed through the cavity of the mold with a ram or by blowing or suction. Additional cooling is therefore, especially in this area, of importance for increasing production speed.
K tome se lakoobradivi plašt može bez poteškoća opremiti provrtima, utorima i sličnim, npr. za učvršćivanje na držaču kalupa. In addition, the easy-to-process casing can be easily equipped with holes, slots and the like, for example for fixing on the mold holder.
Uložak je od materijala, koji se prije svega odlikuje velikom toplinskom provodljivošću, kao i razmjerno velikom tvrdoćom. On npr. može biti od čistog kroma, čistog nikla, legure na bazi kroma i nikla, primjerice legure nikal-berilij, kao NiBe2, od metalurških čelika u prahu ili npr. Stellita-6 ili Stellita-21. The insert is made of material, which is primarily characterized by high thermal conductivity, as well as relatively high hardness. It can, for example, be made of pure chromium, pure nickel, an alloy based on chromium and nickel, for example a nickel-beryllium alloy, such as NiBe2, of metallurgical steel powder or, for example, Stellita-6 or Stellita-21.
Budući da je kako plašt, tako i uložak kalupa prema izumu, od relativno dobro toplinski provodljivog materijala, može se toplina odgovarajuće brzo odvesti iz šupljine kalupa prema vani i time postići odgovarajuće kratko trajanje takta. Since both the jacket and the mold insert according to the invention are made of a relatively well heat-conducting material, the heat can be adequately quickly removed from the mold cavity to the outside and thereby achieve an appropriately short cycle time.
Uložni dio je pričvršćen na plaštenom dijelu spojem koji zatvara kalup, koji najmanje dopušta uvijanje, manje od 1 mm, npr. 0,2 mm, zbog urednih nasuprotnih uporišta reške kalupa; naprotiv, moguće je slobodno uzdužno istezanje u aksijalnom smjeru. Ovaj spoj, koji zatvara kalup, smješten je prvenstveno u području najvećeg toplinskog opterećenja kalupa. Time se znatno kompenzira toplinska deformacija dijelova kalupa. The insert part is attached to the sheath part with a joint that closes the mold, which allows the least twisting, less than 1 mm, for example 0.2 mm, due to the neat opposite abutments of the edge of the mold; on the contrary, free longitudinal stretching in the axial direction is possible. This joint, which closes the mold, is located primarily in the area of the highest thermal load of the mold. This significantly compensates for the thermal deformation of the mold parts.
Uložak kalupa prema izumu je barem u području bridova kalupa, na plohama koje su u dodiru sa staklom, opremljen slojem otpornim na habanje ili oklopom. Time se sprječava habanje bridova kalupa. Time je, zajedno s neznatnom toplinskom deformacijom kalupa prema izumu, zajamčen uredan šav na proizvedenom staklenom predmetu. The mold insert according to the invention is equipped with a wear-resistant layer or armor at least in the area of the edges of the mold, on the surfaces that are in contact with the glass. This prevents the edges of the mold from wearing out. This, together with the slight thermal deformation of the mold according to the invention, guarantees a neat seam on the produced glass object.
Sloj otporan na habanje nanosi se prvenstveno navarivanjem, štrcanjem pomoću plamena ili izostatičkim prešanjem (HIP). On može biti od legure na bazi nikla i kobalta, npr. kobaltove legure s 25-35% Cr, 0-10% W, do 2% C, 0-5% Ni i 0-8% Mo, kao Stellit-6 (28% Cr, 5% W, 1% C, ostatak: Co) ili Stellit-21 (27% Cr, 0,2%C, 2% Ni, 6% Mo, ostatak: Co) ili Ni-legure s 1 do 6% Fe, 2-5% Si, do 3% B, 0-10% Cr i do 0,5%C, kao Deloro legura br. 40G (7,5% Cr, 0,3% C, 5% Fe, 4% Si, 1,2% B, ostatak: Ni) ili Deloro legura br. 42K (0,1% C, 1% Fe, 3% Si, 2% B, ostatak: Ni), pri čemu podaci u % predstavljaju uvijek težinske %. The wear-resistant layer is applied primarily by welding, flame spraying or isostatic pressing (HIP). It can be a nickel-cobalt based alloy, for example a cobalt alloy with 25-35% Cr, 0-10% W, up to 2% C, 0-5% Ni and 0-8% Mo, such as Stellite-6 ( 28% Cr, 5% W, 1% C, balance: Co) or Stellite-21 (27% Cr, 0.2%C, 2% Ni, 6% Mo, balance: Co) or Ni-alloys with 1 to 6% Fe, 2-5% Si, up to 3% B, 0-10% Cr and up to 0.5% C, as Deloro alloy no. 40G (7.5% Cr, 0.3% C, 5% Fe, 4% Si, 1.2% B, rest: Ni) or Deloro alloy no. 42K (0.1% C, 1% Fe, 3% Si, 2% B, rest: Ni), where the data in % always represent % by weight.
Sloj otporan na habanje može također pokrivati cjelokupnu plohu umetka kalupa, koja je u dodiru sa staklom. The wear-resistant layer can also cover the entire surface of the mold insert, which is in contact with the glass.
Budući da materijali otporni na habanje imaju općenito neznatnu toplinsku provodljivost, sloj otporan na habanje izrađen je što je moguće tanjim. On može imati debljinu od 0,1 mm do 5 mm, osobito 1 mm do 2 mm. Since wear-resistant materials generally have negligible thermal conductivity, the wear-resistant layer is made as thin as possible. It can have a thickness of 0.1 mm to 5 mm, especially 1 mm to 2 mm.
Kalup u dijelovima prema izumu može biti oblikovan kao kalup za prešanje, puhanje ili usisavanje. Njime se mogu proizvesti stakleni predmeti po volji, dakle masivni prešani stakleni predmeti isto tako kao i staklena šuplja tijela, primjerice boce ili čaše. The mold in parts according to the invention can be shaped as a mold for pressing, blowing or suction. It can be used to produce glass objects as desired, i.e. massive pressed glass objects as well as hollow glass bodies, for example bottles or glasses.
U slijedećem se, pomoću crteža, pobliže objašnjava izvedbeni oblik kalupa prema izumu za proizvodnju staklenih predmeta. In the following, with the help of drawings, the embodiment of the mold according to the invention for the production of glass objects is explained in more detail.

Figure 3 section along the line III-III in Figure 1 through the lower part of the mold, where the wear-resistant layer covers the entire surface that is in contact with the glass.
Kalup se sastoji od dvije polovice kalupa 1, 2, a svaka polovica 1, 2 od plaštenog dijela 3, 4 i uložnog dijela 5, 6. The mold consists of two halves of the mold 1, 2, and each half 1, 2 of the jacket part 3, 4 and the insert part 5, 6.
Plašt od oba plaštena dijela 3, 4 i uložak od oba uložna dijela 5, 6 oblikuju se uvijek kao šuplji cilindar, koaksijalan prema uzdužnoj osi 7. Plašteni dijelovi 3, 4 i uložni dijelovi 5, 6 svake polovice kalupa leže također cilindričnom dodirnom plohom 8 punom površinom jedan na drugom. The shell of both shell parts 3, 4 and the insert of both insert parts 5, 6 are always shaped as a hollow cylinder, coaxial to the longitudinal axis 7. The shell parts 3, 4 and insert parts 5, 6 of each half of the mold also lie with a cylindrical contact surface 8 full surface on top of each other.
Uložni dijelovi 5, 6 zatvaraju šupljinu kalupa 10, u koju se unosi staklena talina 11, prvenstveno u obliku kaplje, kako je to na slici 2 prikazano crtkano. The insert parts 5, 6 close the cavity of the mold 10, into which the glass melt 11 is introduced, primarily in the form of a drop, as shown in dashed lines in Figure 2.
Kalup prikazan na crtežu služi za proizvodnju bočica za dojenče. Koaksijalno udubljenje 13 na gornjem, odnosno 14 na donjem kraju služi uvijek za centriranje polovica kalupa alata, koji ovdje dalje nije prikazan, kojim se proizvodi grlić, odnosno dno boce. The mold shown in the drawing is used for the production of baby bottles. The coaxial indentation 13 at the upper end, or 14 at the lower end, is always used for centering the mold halves of the tool, which is not shown here, which produces the neck, or the bottom of the bottle.
Kaplja staklene taline 11 utisne se batićem, koji nije prikazan, u stakleni predoblik, iz kojeg se tada puše bočica u puhani oblik, koji nije prikazan. A drop of glass melt 11 is pressed with a mallet, which is not shown, into a glass preform, from which the bottle is then blown into a blown form, which is not shown.
Uložni dijelovi 5, 6 su na svojoj unutarnjoj plohi 17, 18, koja je u dodiru sa staklom, opremljeni slojem otpornim na habanje 20 (slika 3). Sloj otporan na habanje ili oklop može biti predviđen, kako je to prikazano na slici 1 slojem 20', također samo u području bridova 15, 16 između unutarnjih ploha 17, 18, koje su u dodiru sa staklom i razdjelnih ploha 28, 29 u razdjelnoj ravnini 19 uložnih dijelova 5, 6 i plaštenih dijelova 3, 4. The insert parts 5, 6 are equipped with a wear-resistant layer 20 on their inner surface 17, 18, which is in contact with the glass (Figure 3). A wear-resistant layer or armor can be provided, as shown in Figure 1 by the layer 20', also only in the area of the edges 15, 16 between the inner surfaces 17, 18, which are in contact with the glass and the dividing surfaces 28, 29 in the dividing plane 19 of insert parts 5, 6 and sheath parts 3, 4.
Svaki plašteni dio 3, 4 ima za pričvršćenje polovica kalupa 1, 2 na držaču kalupa stroja za oblikovanje, koji nije prikazan, vez 21 s prstenastim utorom 22 (slika 2), uzdužnim utorima 23 (slika 1) i provrtima 24 (slika 3). Each sheathed part 3, 4 has a connection 21 with an annular groove 22 (figure 2), longitudinal grooves 23 (figure 1) and holes 24 (figure 3) for fixing the halves of the mold 1, 2 on the mold holder of the molding machine, which is not shown. .
Da bi se polovice kalupa 1, 2 fiksirale u radijalnom smjeru, predviđen je spoj za zatvaranje kalupa, koji se sastoji od uzdužnog utora 26 predviđenog na razdjelnoj plohi 29 plaštenog dijela 4, u koji ulazi uzdužno pero 27, predviđeno na razdjelnoj plohi 28 drugog plaštenog dijela 3. Time se ne sprječava istezanje kalupa u uzdužnom smjeru. In order to fix the halves of the mold 1, 2 in the radial direction, a joint for closing the mold is provided, which consists of a longitudinal groove 26 provided on the dividing surface 29 of the jacket part 4, into which a longitudinal tongue 27, provided on the dividing surface 28 of the second jacket, enters. of part 3. This does not prevent the stretching of the mold in the longitudinal direction.
Za fiksiranje uložnih dijelova 5, 6 na plaštenim dijelovima 3, 4 na svakoj polovici kalupa 1, 2, na obje razdjelne plohe 28, 29 s obje strane šupljeg prostora 10, predviđeni su vijci s glavom 30 do 35, koji ulaze u provrte s navojem 36 do 39, koji se protežu tangencijalno u plaštenim dijelovima 3, 4. Glava 40 svakog vijka s glavom 30 do 33 je potpuno upuštena u udubljenje 43 do 46 u razdjelnoj plohi 28, 29 plaštenih dijelova 3, 4. For fixing the insert parts 5, 6 on the coated parts 3, 4 on each half of the mold 1, 2, on both dividing surfaces 28, 29 on both sides of the hollow space 10, head screws 30 to 35 are provided, which enter the threaded holes. 36 to 39, which extend tangentially in the shell parts 3, 4. The head 40 of each head screw 30 to 33 is completely recessed in the recess 43 to 46 in the dividing surface 28, 29 of the shell parts 3, 4.
Na udubljenje 43 do 44 u plaštenim dijelovima 3, 4 nastavlja se udubljenje 47 do 50 na razdjelnoj plohi 28, 29 uložnih dijelova 5, 6. Udubljenja 43 do 46 u plaštenim dijelovima 3, 4 i uvijek susjedna udubljenja 47 do 50 u uložnim dijelovima 5, 6 zajedno tvore kružno oblikovano udubljenje za smještaj dotičnog vijka s glavom 40. The recesses 43 to 44 in the sheathed parts 3, 4 continue with the recesses 47 to 50 on the dividing surface 28, 29 of the insert parts 5, 6. The recesses 43 to 46 in the sheathed parts 3, 4 and always adjacent recesses 47 to 50 in the insert parts 5 , 6 together form a circularly shaped recess for accommodating the respective head screw 40.
Glavama 40 vijaka s glavom 30 do 35, koje su smještene u udubljenja 47 do 50 u uložnim dijelovima 5, 6, fiksira se uložni dio 5, 6 na plaštenom dijelu 3, 4. Kako je prikazano na slici 1 pomoću glave 40, smještena je upušteno glava 40 u udubljenje 47 uložnog dijela 3 s postranom zračnosti 52, da bi se osiguralo uzajamno pomicanje uložnih dijelova 5, 6 i plaštenih dijelova 3, 4 u uzdužnom smjeru. The heads 40 of the screws with the head 30 to 35, which are located in the recesses 47 to 50 in the insert parts 5, 6, fix the insert part 5, 6 on the sheathed part 3, 4. As shown in Figure 1 by means of the head 40, it is placed recessed head 40 in recess 47 of insert part 3 with lateral clearance 52, to ensure mutual movement of insert parts 5, 6 and sheath parts 3, 4 in the longitudinal direction.
Dubina a udubljenja 47 do 50 u uložnim dijelovima 5, 6 je veća od dubine a' udubljenja 43 do 46 u plaštenim dijelovima 3, 4. The depth a of the recesses 47 to 50 in the insert parts 5, 6 is greater than the depth a' of the recesses 43 to 46 in the sheathed parts 3, 4.
Time su uložni dijelovi 5, 6 u plaštenim dijelovima 3, 4 okretljivo umetnuti u ležaj sa zračnosti, koja odgovara razlici između a i a'. Ova zračnost može npr. iznositi 0,1 mm. Plivajućim uležištenjem uložnih dijelova 5, 6 nepropusno se zatvara reška 51 na razdjelnim plohama 28, 29 uložnih dijelova 5, 6. In this way, the insert parts 5, 6 in the shell parts 3, 4 are rotatably inserted into the bearing with a clearance that corresponds to the difference between a and a'. This clearance can be, for example, 0.1 mm. The floating placement of the insert parts 5, 6 seals the slot 51 on the dividing surfaces 28, 29 of the insert parts 5, 6.
Uložni dijelovi 5, 6 fiksirani su dalje na plaštenim dijelovima 3, 4 spojem koji zatvara kalup, koji sprječava uzajamno pomicanje uložnih dijelova 5, 6 i plaštenih dijelova 3, 4 u uzdužnom smjeru. The insert parts 5, 6 are further fixed on the sheathed parts 3, 4 by a joint that closes the mold, which prevents mutual movement of the insert parts 5, 6 and the sheathed parts 3, 4 in the longitudinal direction.
Ovaj spoj koji zatvara kalup, formira se pomoću dosjednog klina 53, 54 na svakom plaštenom dijelu 3, 4, koji je smješten u odgovarajućem udubljenju 55, 56 u plaštenom dijelu i ulazi u uložni dio 5, 6. Dosjedni klinovi 53, 54 učvršćeni su na vijku s glavom 57, 58, koji je smješten u radijalnom provrtu 59, 60 u plaštenom dijelu 3, 4. Spoj koji zatvara kalup smješten je prvenstveno u području najvećeg toplinskog opterećenja kalupa, koje se općenito nalazi tamo, gdje sjedne kaplja staklene taline 11, prije nego se utisne batićem. This connection, which closes the mold, is formed by means of an adjacent pin 53, 54 on each shell part 3, 4, which is located in a corresponding recess 55, 56 in the shell part and enters the insert part 5, 6. The adjacent pins 53, 54 are fixed on the screw with the head 57, 58, which is located in the radial bore 59, 60 in the jacket part 3, 4. The joint that closes the mold is located primarily in the area of the highest thermal load of the mold, which is generally located where the drop of glass melt sits 11 , before it is pressed with a mallet.
Da bi se kalup hladilo, u dijelovima plašta 3, 4 predviđeni su rashladni kanali 62, koji prolaze duž dodirne plohe 8 između plaštenih dijelova 3, 4 i uložnih dijelova 5, 6. Rashladni kanali 62, koji su na slici 2 prikazani crtkano, protežu se u području najvećeg toplinskog opterećenja (kaplja staklene taline 11) kalupa i prema vani. In order to cool the mold, cooling channels 62 are provided in the shell parts 3, 4, which pass along the contact surface 8 between the shell parts 3, 4 and the insert parts 5, 6. The cooling channels 62, which are shown in dashed lines in Figure 2, extend is in the area of the highest heat load (droplet of glass melt 11) of the mold and towards the outside.
Za izmjenu uložnih dijelova 5, 6 otvori se kalup, na što se odstrane vijci 30 do 35. Zatim se dotični uložni dio 5, 6 povuče prema unutra, da bi se dosjedne klinove 53, 54 i time uložni dio 5, 6 oslobodilo od plaštenog dijela 3, odnosno 4. To change the insert parts 5, 6, the mold is opened, after which the screws 30 to 35 are removed. Then the respective insert part 5, 6 is pulled inward, in order to free the adjacent pins 53, 54 and thus the insert part 5, 6 from the jacket of part 3, respectively 4.
