射芯機加熱裝置的結構設計
(1)電加熱板:電加熱板采用HT200或HT250灰鑄鐵經(jīng)機械加工而成。加熱板的尺寸大小,除滿足電加熱元件的安放外,還應與選用的射芯機技術規(guī)格和熱芯盒外形相互適應。單工位垂直分盒熱芯盒射芯機附有通用電加熱板,可直接采用,一般屬于整鑄式的加熱板。二工位水平分盒熱芯盒加熱板,由上、下兩塊加熱板用M8內(nèi)六角螺釘緊固構成。
(1) electric heating plate: the electric heating plate is machined by HT200 or HT250 gray cast iron. The size of the heating plate not only satisfies the placement of the electric heating element, but also adapts to the technical specifications of the selected core shooter and the shape of the hot box. The single station vertical box heat box core shooting machine is equipped with universal electric heating plate, which can be directly used, generally belongs to the whole casting type heating plate. The two working position horizontal box heat box heating plate is composed of upper and lower two heating plates which are fastened by six angle screws in M8.
(2)電加熱元件:電加熱元件又稱電加熱管。電加熱管有兩種形式,一種是單端出線的,另一種是雙端出線的。
(2) electric heating element: electric heating element, also called electric heating tube. There are two forms of electric heating tubes, one is single ended outlet, the other is double outlet.
(3)電加熱功率的確定:首先要確定加熱功率,然后才能確定電加熱元件的規(guī)格和數(shù)量,并合理布置電加熱管。
(3) determination of electric heating power: first, determine the heating power, then determine the specification and quantity of the electric heating element, and arrange the electric heating tube reasonably.
(4)電加熱管的數(shù)量和布置:根據(jù)所確定的加熱功率以及芯盒的大小、砂芯的形狀、機器的工作特點等,選擇合適型號和長度的電加熱管。一般每個芯盒最少放三根。其布置應力求使芯盒加熱均勻。布置加熱管時,應注意不與其他零件及機構,如頂芯桿、回應導桿。排氣塞等相碰。
(4) the quantity and arrangement of the electric heating tube: according to the heating power and the size of the core box, the shape of the core and the working characteristics of the machine, the electric heating pipe of the suitable type and length is selected. In general, each core box is at least three. Its arrangement should make every effort to make the core box warm even. When placing heating pipes, attention should be paid to other parts and mechanisms such as mandril and responsive guide bar. Exhaust plug and other collision.
