Hard alloy molds, inozivikanwa se "amai veindasitiri," inoita basa rakakosha mukugadzirwa kwemazuva ano.Asi zviumbwa zvakavapo sei, uye zvakatanga rini?
(1) Kuvandudzwa kweMasimba Anobereka seSocial Foundation yeMold Creation
Iko kushandiswa kwema mold kwakanangana nekudzokorora zvinhu zvechimiro chimwe chete, nekudaro kunowedzera kugona kwekugadzira uye kunaka.Mumwe wavavambi veMarxism, Friedrich Engels, muzivi weGermany, muzivi, mufungo, uye mupanduki, akamboti, “Kana pangova nechinodikanwa chounyanzvi munzanga, ichi chinodikanwa chichasunda sayenzi mberi mayunivhesiti anopfuura gumi.”Kana nzanga yasvika pane imwe nhanho yebudiriro uye vanhu vane chinodikanwa chakakosha chekushandisa zvinhu zvakafanana, zvakashongedzerwa tekinoroji uye maturusi anoenderana, molds inongovapo.
(2) Kuwanikwa uye Kushandiswa kweMhangura seNheyo Yezvinhu zveHard Alloy Mold Creation.
Dzimwe nyanzvi dzinotenda kuti kuberekwa kwechokwadi kwezviumbwa kwakaitika munguva yeBronze Age, makore angangoita 5000 kusvika ku7000 apfuura.Nguva iyi yaitenderera nekushandiswa kwemhangura sechinhu chekutanga chekugadzira maturusi akasiyana siyana ekugadzira, midziyo yemazuva ese, uye zvombo, zvakaita semagirazi emhangura, hari, nemapakatwa.Munguva ino, mamiriro ekutanga ekugadzirwa kweakaoma alloy molds akange atovepo, kusanganisira metallurgical tekinoroji, kugadzirwa kwemazhinji, uye maworkshops ekugadzirisa.Zvisinei, kugadzira mold panguva iyi kwakanga kuchiri kutanga uye kure nekukura.
Kuuya kwe mold kwakaratidza chiitiko chakakosha munhoroondo yevanhu, kushandura nzira dzekugadzira uye kusimudzira nzanga kubudiriro yetekinoroji nekuwedzera goho.Nokufamba kwenguva, kugadziridzwa uye kunatswa kwezviumbwa zvakaramba zvichiumba maindasitiri akasiyana-siyana, zvichiita kuti nyika irambe ichichinja-chinja yekugadzirwa kwemazuva ano.”
Kuitwa kwezvakaoma alloy mold zvinhu kunosanganisira ma mechanical properties, high-temperature properties, surface properties, processability, uye economic properties, pakati pezvimwe.Mhando dzakasiyana dze mold dzine mamiriro ekushanda akasiyana, izvo zvinoguma nezvinodiwa zvakasiyana zvekushanda kwezvinhu.
1. Kune kutonhora kushanda molds, kuoma kwepamusoro, simba, uye kupfeka kwakanaka kwekudzivirira zvakakosha.Pamusoro pezvo, ivo vanofanirwa kuve nehukuru hwekumanikidza simba, kusimba kwakanaka, uye kuramba kuneta.
2. Panyaya yekupisa kushanda nesimba alloy molds, kunze kweambient ambient tembiricha zvivakwa, ivo vanofanirwa kuratidza yakanakisa ngura kusagadzikana, kudzikama kugadzikana, yakakwirira-tembiricha oxidation kuramba, uye kupisa kuneta kuramba.Izvo zvinodiwawo kuti vave nediki diki yekuwedzera yekupisa coefficient uye yakanaka yekupisa conductivity.
3. Iyo mold cavity surface inofanira kuva nekuoma kwakakwana uku ichichengetedza zvose kuoma uye kupfeka kuramba.
Dzvinyiriro die-casting molds dzinoshanda pasi pemamiriro ezvinhu akaomarara, dzichida kuti maforoma alloy akaomarara ave nekunaka kupfeka kuramba, kupisa kupisa, kumanikidza simba, uye oxidation kuramba, pakati pezvimwe zvivakwa.
