（1）設備特點 水平脫箱造型線分垂直向下射砂和水平側面射砂兩種模式。

(1) the characteristics of the equipment are the two models, namely, the off the box molding line, the vertical downward shooting sand and the horizontal side sand shooting.

（2）鑄件特點 根據鑄件的結構、尺寸大小、材質、重量等進行工藝分析。需特別指出的是，鑄件在分型面上凹坑太深，吊砂部分型腔的緊實度不高；或模樣太高，其背面型腔的緊實度同樣也不高，會在澆注時極易產生砂眼等鑄造缺陷。因為現在多數水平分型脫箱造型線采用垂直向下射砂的加砂模式，大動力液壓擠壓、壓實，水平方向起模。這種模式決定了上述問題很難避免。當鑄件水平分型凸凹落差較大時，若采用水平側面射砂時，受模具凸起部分的阻力，會使射砂背面的型砂硬度不夠，導致掉砂或鑄型不完整。設計人員在設計模具時要設計出射砂通道，確保型砂硬度一致。具體依據鑄件的結構、外形尺寸、落差大小選用造型線。落差太大，砂胎凸起太高或凹入太深時不宜采用側面射砂。

(2) the casting characteristics are analyzed according to the structure, size, material and weight of the casting. It is necessary to point out that the castings are too deep in the subsurface, and the tightness of the sling part of the cavity is not high, or the shape is too high, and the tightness of the back cavity is also not high, and it will easily produce casting defects such as the sand eye in the casting. Because most of the horizontal parting molding line adopts sand filling mode with vertical downward shooting, large power hydraulic extrusion and compaction, and horizontal lifting. This model determines that the above problems are difficult to avoid. When the horizontal profile of the casting is large, when the horizontal side is used, the resistance of the protruding part of the mold will not be enough, which causes the sand or the mold to be incomplete. When designing the mold, the designer should design sand shooting passages to ensure that the hardness of the molding sand is the same. The molding line is selected according to the structure, size and size of the casting. When the drop is too large, the sand blasting is too high or the concave is too deep.

（3）生產綱領 根據生產任務要求確定生產綱領后，對鑄造生產任務進行工藝分析是設備選型時的一個重要環節。確定一個具有代表性的鑄件對其進行詳細的工藝分析。例如:每型設置鑄件的數量、使用砂芯的種類及數量，然后根據工藝分析確定所選用的水平分型脫箱造型線的下工位數量及效率。一般情況下，水平分型脫箱造型線有單工位、雙工位、四工位供選用。設計效率80～180型/h。一方面可避免因選擇的生產線效率低而造成生產能力不足，另一方面也要避免因選擇的生產線效率過高而使生產線的整個運行成本增加。

(3) production planning is an important part of equipment selection when the production plan is determined according to the production tasks. A representative casting is determined to carry out detailed process analysis. For example, the number of each type of casting, the type and quantity of the sand core are used, and then the number and efficiency of the bottom position of the selected horizontal split box molding line are determined according to the process analysis. Under normal circumstances, the horizontal split stripping molding line has single station, double station and four stations for selection. Design efficiency 80~180 type /h. On the one hand, the low productivity of the selected production line can be avoided. On the other hand, the overall operation cost of the production line should be increased by avoiding the high efficiency of the selected production line.

（4）相關工部配套 以水平分型脫箱造型線為服務對象，詳細計算設計砂處理工部、熔煉工部、制芯工部等,讓造型線上每一工位均需在一定時間內保質、保量、有節奏地進行，使熔煉、混砂、造型、澆注相互匹配，最大發揮設備的效能。另外，在造型線上配套澆注機，可使其效率提高20%以上。

(4) the relevant ministry of work is equipped with a horizontal typed off box modeling line as the service object, detailed calculation and design of the sand processing department, the smelting department and the core work department, so that every station in the molding line should be guaranteed, guaranteed and rhythmical in a certain time, making the melting, mixing, molding and pouring match each other to the maximum. The effectiveness of the preparation. In addition, the casting machine on the molding line can increase its efficiency by more than 20%.
