Machine ya kosala ba moulages na injection .
The injection molding machine (core injection machine) uses compressed air to evenly inject molding sand into the sand box for pre-compaction, and then applies pressure for compaction. The core injection machine uses coated sand for core making and is suitable for both hot core boxes and cold core boxes. The feature of the core shooting machine is that it uses two guide columns, opens and closes the mold for vertical separation, and installs two different molds simultaneously. The middle fixed frame can be installed on both sides to fix the mold and open and close the mold left and right. Core shooting machines are widely used in the foundry industry. The cores produced by core shooting machines have precise dimensions and smooth surfaces. The working principle of the core injection machine is to inject the core sand mixture with liquid or solid thermosetting resin as the binder into the heated core box. The sand Core ezali préchauffée na kati ya boîte de noyau mpe noki noki ekómi makasi tii na épaisseur moko boye (pene na 5 kino 10 mm), na nsima babimisaka yango mpo na kosala produit ya noyau ya zelo ya qualité ya likolo oyo ezali na surface ya lisse mpe ba dimensions ya sikisiki.
Core shooting machines have been widely used in recent years. This is because using core shooting machines for molding can save the high wages of molding workers. Because multiple boxes are stacked for pouring, it can also reduce the waste of gates and risers. The coated sand after pouring has good collapsible properties, which is conducive to sand cleaning. The core shooting machine has a high production efficiency, precise sand mold dimensions, and can appropriately Bokitisaka volume ya traitement. Opération ezali simple mpe rendement ya ba castings ezali ya likolo. Ba fonderies mingi elingi kosalela ba machines ya core-shooting mpo na moulage.
Bokeli ya masini ya kokanga bilili ya moboko ezali mingimingi na biloko minei ya minene.
1. Ba composants ya colonne : mingi mingi composé ya ba crossbeams na ba colonnes, esali cadre ya likolo ya équipement. Cylindre ya sable, trémie ya sable, ba composants ya valve ya sable, cylindre ya kofina na ba parties misusu etiemaka na crossfaisement pona kosala système ya alimentation ya sable na gaz pona core-making.
2. Sand injection device: It is composed of components such as the sand cylinder, air valve, sand cylinder frame, nozzle, and sand injection plate. During operation, the sand cylinder is pressed tightly against the upper plane of the core box by the pressing cylinder, and the sand injection valve is opened for sand injection. After the exhaust sand injection is completed, release the compression cylinder (return to the original position) to complete the sand injection and sand addition work.
3. Ba composants ya base ya moule: mingi mingi composé ya ba coffrages oyo ezali kotambola, ba plaques ya soutien gauche na droite, ba poteaux ya guide, ba manches ya guide, ba barres d'éjecteur, ba cylindres ya kokanga moule mpe ba parties mosusu.
3.1 Cadre mobimba ya moule ya machine ya moulage ya injection etiemaka na base na ba plaques ya soutien gauche na droite.
3.2 Modèle oyo ezali kotambola ezali kotambola na lobɔkɔ ya mwasi mpe ya mobali na nzela ya likonzi ya kotambwisa na nse ya kopusama mpe kobenda ya molangi ya kokangama mpo na kosilisa mosala ya kosala moboko ya kokanga mpe kofungola molangi. Ntango bafungolaka coffrage oyo ezali kotambola, moboko ya zelo oyo ezali na etanda ya moboko ya likoló epusami libanda na lingenda ya likoló na coffrage oyo ekangami, mpe ekoki kolongola yango na pɛtɛɛ nyonso na mabɔkɔ.
3.3 Base: Support mobimba, cadre ya moule, colonne, boîte de commande électrique, valve solenoïde, etc. ya machine ya moulage injection etiemaka na base.
