農(nóng)田水利U型槽模具   河北宏旭模具

         農(nóng)田水利U型槽模具  水利U型槽模具主要用于鐵路，高鐵，城際鐵路的路基，站臺(tái)電纜方面。從2008年高鐵的普及之后高鐵的大大小小工程接踵而來(lái)，高鐵兩側(cè)的電纜槽主要采用混凝土預(yù)制而成的，鐵路線路有多長(zhǎng)，兩側(cè)的電纜就需要有多長(zhǎng)，所以電纜槽工程量也是相當(dāng)大的。農(nóng)田水利U型槽模具  水利U型槽模具的預(yù)制混凝土要求比較嚴(yán)格一般需要達(dá)到c40混凝土，必須保證工程的結(jié)實(shí)程度。農(nóng)田水利U型槽模具  水利U型槽模具具一般有兩種材質(zhì)可以選擇，abs樹(shù)脂，4mm鋼板。常用規(guī)格主要用ABS因?yàn)樗芰系囊阋撕芏?，非常?guī)的主要采用鋼模板，鋼模板的優(yōu)勢(shì)主要體現(xiàn)在它的穩(wěn)固耐用上面。澆注系統(tǒng)：將塑料由少射機(jī)噴嘴引向型腔的流道稱(chēng)為澆注系統(tǒng),由主流道，分流道，澆口。熱交換系統(tǒng)：為了滿足注射成形工藝對(duì)模具溫度的要求需要對(duì)模具溫度進(jìn)行較的控制。頂出系統(tǒng)：實(shí)現(xiàn)塑膠產(chǎn)品脫模的機(jī)構(gòu)，其結(jié)構(gòu)形式很多，常用的是頂針、司筒和推板等脫模機(jī)構(gòu)。排氣系統(tǒng)：將型腔內(nèi)空氣導(dǎo)出的結(jié)構(gòu)，如：排氣槽及鑲件配合時(shí)的間隙。Farmland water conservancy U-groove mould water conservancy U-groove mould is mainly used for Subgrade and platform cable of railway, high-speed railway and intercity railway. Since the popularity of high-speed rail in 2008, large and small projects of high-speed rail have followed. The cable trays on both sides of high-speed rail are mainly prefabricated with concrete. The length of the railway line depends on the length of the cables on both sides, so the quantities of cable trays are also quite large. The precast concrete requirements of U-groove mould for farmland and water conservancy are relatively strict. Generally, it needs to reach C40 concrete, and the firmness of the project must be guaranteed. Farmland water conservancy U-groove mould water conservancy U-groove mould generally has two materials to choose from, ABS resin and 4mm steel plate. Common specifications mainly use ABS, because plastic is much cheaper. Unconventional ones mainly use steel formwork. The advantages of steel formwork are mainly reflected in its stability and durability. Gating system: the flow channel that leads the plastic from the nozzle of the less ejector to the cavity is called the gating system, which consists of the main flow channel, shunt channel and gate. Heat exchange system: in order to meet the requirements of injection molding process for mold temperature, it is necessary to control the mold temperature. Ejector system: it is a mechanism for demoulding plastic products. It has many structural forms. Commonly used demoulding mechanisms are ejector pin, cylinder and push plate. Exhaust system: the structure that leads the air in the cavity, such as the clearance when the exhaust slot and insert are matched.
