Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0016] See the accompanying drawings: the pressing mechanism 1-1 of the fixed mold of the lead-acid battery grid continuous casting machine in the figure, including the screw 3, and the screw sleeve 6 located inside the guide sleeve 5;
[0017] After the screw rod 3 is threadedly matched with the screw sleeve 6, it is supported in the bearing sleeve 4 through the bearing 4-1;
[0018] The end of the screw sleeve 6 that is not matched with the screw 3 has an inner cylinder that can accommodate a pressure sensor 7 and a spring 8;
[0019] One end of the spring 8 is connected to the pressure sensor 7 , and the other end is connected to the push rod 9 .
[0020] In the embodiment, the end of the screw 3 not matched with the screw sleeve 6 is connected with the handwheel 2 . In order to adjust the pressing mechanism by rotating the screw rod 3 .
[0021] The pr...

The invention aims to provide a hold-down mechanism of a fixed mould of a gird continuous casting machine of a lead-acid storage battery for adjusting distance between a movable mould and the fixed mould of the grid continuous casting machine. The hold-down mechanism comprises a screw rod and a screw rod sleeve which is located in a guide sleeve; the screw rod is threaded with the screw rod sleeve, and then supported in a bearing sleeve by a bearing; an internal cylinder capable of holding a pressure sensor and a spring is arranged at one end of the screw rod sleeve which is not matched with the screw rod; one end of the spring is connected with the pressure sensor while the other end thereof is connected with an ejector pin. The hold-down mechanism can both avoid overflow of liquid lead out of the cavity because of too large match gap of the moulds and prevent power loss of the continuous casting machine and abrasion of the surface of the mould because of increased friction force between the fixed mould and the movable mould due to too small match gap of the moulds during a work progress.
Description
technical field [0001] The invention relates to equipment for continuous metal casting, in particular to a pressing mechanism for a fixed mold of a lead grid continuous casting machine. Background technique [0002] The cooperation between the molds of the battery grid continuous casting machine is extremely important for the forming process of the battery grid. The Chinese patent with publication number CN101670422A discloses a lead plate continuous casting machine. The invention adopts two rollers fixed on the support table and having a gap to extrude the lead plate for molding. Due to thermal expansion and contraction of the rolls during the production process, the gap changes, which affects the thickness of the cast product. Contents of the invention [0003] The object of the present invention is to provide a pressing mechanism for fixed mold of lead-acid storage battery grid continuous casting machine. The continuous casting machine to which the pressing mechanism...
