The utility model discloses a lifting device for a vulcanizing machine, which comprises a base, a support table, a main oil cylinder, a main oil pipe and a main oil pump. A control box is provided on one side of the base, and a liquid controlled one-way valve is provided in the main oil pipe, and an auxiliary oil cylinder is provided on both sides of the base. One end of the auxiliary oil pipe is connected with an auxiliary oil pump, and an electromagnetic valve is provided in the auxiliary oil pipe. A pressure sensor is provided on the top surface of the support table. The pressure sensor is connected with the input end of the control box. The output end of the control box is connected with the main oil cylinder, the auxiliary oil cylinder and the electromagnetic valve, because the auxiliary oil cylinder is compared with the main oil cylinder. Oil cylinder is small, so in the case of the same injection speed, the speed of the auxiliary cylinder is faster than the main oil cylinder. Therefore, when the supporting platform is promoted, the auxiliary oil cylinder is promoted. Only when the pressing die is really needed, the main oil cylinder is relied on, thus the speed of the support platform is accelerated and the quality of the product is guaranteed.
【技术实现步骤摘要】
一种硫化机用升降装置
本技术涉及一种升降机构,尤其是一种硫化机用升降装置。
技术介绍
目前,在现有的硫化机中,在支撑台的下方设有三个主油缸,模具是放置在支撑台上,由于主油缸本身比较大,所以在提升时,主油缸伸长的速度就很慢,因此胶条在模具内放置的时间就变长,从而导致产品的硫化效果不理想。
技术实现思路
本技术的技术任务是针对以上现有技术的不足,而提供一种硫化机用升降装置。本技术解决其技术问题所采用的技术方案是:一种硫化机用升降装置,包括底座、支撑台、主油缸、主油管和主油泵,其中在所述底座的一侧设有控制盒,在所述主油管内设有液控单向阀,在所述底座的两侧设有副油缸,所述副油缸连接有副油管,在所述副油管的一端连接有副油泵,在所述副油管内设有电磁阀,在所述支撑台的顶面设有压力传感器,所述压力传感器与所述控制盒的输入端连接,所述控制盒的输出端分别与所述主油缸、副油缸和电磁阀连接。进一步改进:在所述支撑台的两侧设有支撑块,所述副油缸的顶部与所述支撑块连接。进一步改进:所述电磁阀为液控单向阀。本技术的优点:由于副油缸比主油缸小,所以在注油速度相同的情况下,副油缸提升的速度要比主油缸快,因 ...
