Die Erfindung betrifft ein Auswerfersystem für Kernkästen, mit einem Rahmen (15) aus einer oberen Tragplatte (17), auf der fest ein Werkzeugunterteil(16) montiert ist, einer unteren Tragplatte (18) und die beiden Tragplatten verbindenden Säulen (20). In dem Rahmen ist zwischen den beiden Tragplatten eine dritte oder mittlere Platte (3) an den Säulen beweglich geführt. Auf den Säulen zwischen der oberen Tragplatte (17) und der mittleren Platte (3) sind Schraubenfedern (21) angeordnet, welche im Ruhezustand die mittlere Platte nach unten gegen auf der unteren Tragplatte (18) angeordnete Anschläge (24) vorspannen, und bei dem an der mittleren Platte (3) ein schaftförmiger Auswerferteil (1) montiert ist. Die Anschläge sind in Bezug auf den Auswerferteil (1) so angeordnet, dass im Ruhezustand des Systems die obere Stirnfläche des Auswerferteils (1) mit der Oberseite des Werkzeugunterteils (16) in einer Ebene liegt, und zum Ausgleich der verschiedenen Wärme-Ausdehnungskoeffizienten zwischen dem Führungsteil (16) und dem metallenen Auswerferteil (1) in der Kammer (22) ist eine Justiervorrichtung (7,8) zur Feinjustierung der relativen axialen Position des Kopfteils (1a) vorgesehen. Bei Temperaturänderungen lassen sich einfach und genau Dehnungsunterschiede in axialer Richtung von Auswerfer- und Unterteil ausgleichen.

| PURPOSE: A method for forming high strength sand mold which is appropriate for fabricating a casting stainless steel exhaust manifold having thickness of 2 to 3 mm, reduces the consumption of material such as sand and improves degree of freedom in designing products is provided. CONSTITUTION: The method for forming high strength sand mold comprises the steps of forming an injection space of sand by closely adhering diaphragm mounted between pattern and back pattern toward the back pattern; injecting sand mixed with binder and hardener into a space between the pattern and back pattern; flattening the injected sand by pressing the diaphragm toward the pattern; hardening a mold by blowing a hardening promoting gas into the pressed sand; separating the diaphragm from the fabricated mold; and stripping the mold off the pattern using an ejector pin, wherein rubber diaphragm is used as the diaphragm, and the step of hardening a mold by blowing a hardening promoting gas comprises the step of pressurizing the blown hardening promoting gas using air so that the blown hardening promoting gas is evenly permeated into the mold to promote hardening of the mold. | ||||||
