Problems solved by technology
[0002] Existing ferrite automatic grouting molds generally use steel ball check valves, hydraulic check valves or angle valves to realize the process of grouting into the mold, so that the valves of the mold during the product forming process Material leakage is easy to occur, and the valve is easy to wear, which makes the maintenance frequency of the mold high; at the same time, the pressure in the mold channel cannot be released after the product in the mold is formed, so that the mold is in the demoulding process. Mold spraying, which in turn affects the appearance of the product

Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0015] Please refer to figure 1 , the special valve 100 for ferrite automatic grouting mold injection provided by the present invention includes a valve body 10, and a valve core 20 arranged in the valve body 10 is used in conjunction with the valve core 20 to realize the valve body 10. The V-shaped sandwich fabric rubber sealing ring 30 for sealing the passage 11, and the air cylinder or hydraulic cylinder 40 for driving the spool 20.
[0016] The valve body 10 is the main part of the special valve 100 for grouting, and the valve body 10 is provided with an inlet 12 , a channel 11 and an outlet 1...

The invention provides a special injection valve for a full-automatic ferrite slurry injection mold. The special injection valve comprises a valve body. The valve body is provided with a feed port, a channel and a discharge port which communicate with one another; a valve element is arranged in the channel of the valve body, and the valve element partially extends out relative to the valve body; the end, extending into the channel, of the valve element is provided with a V-shaped fabric rubber seal ring; the V-shaped fabric rubber seal ring is matched with the valve element to seal the channel; the end, extending out of the channel, of the valve element is connected with a telescopic rod of an air cylinder or a telescopic rod of a hydraulic cylinder to drive the valve element to be matched with the V-shaped fabric rubber seal ring to control opening or closing of the channel; an O-shaped seal ring is arranged at the surface, intersecting with the V-shaped fabric rubber seal ring, of the channel of the valve body; a Y-shaped seal ring is arranged at the surface, intersecting with the valve element, of the channel. The special injection valve for the full-automatic ferrite slurry injection mold is low in manufacturing cost, convenient to maintain, capable of preventing outleakage and free of material leakage; the valve element is not prone to abrasion and long in service life; meanwhile no material spraying happens during demolding.
Description
technical field [0001] The invention relates to a valve body, in particular to a special valve for ferrite automatic grouting mold injection. Background technique [0002] Existing ferrite automatic grouting molds generally use steel ball check valves, hydraulic check valves or angle valves to realize the process of grouting into the mold, so that the valves of the mold during the product forming process Material leakage is easy to occur, and the valve is easy to wear, which makes the maintenance frequency of the mold high; at the same time, the pressure in the mold channel cannot be released after the product in the mold is formed, so that the mold is in the demoulding process. Mold spraying, which in turn affects the appearance of the product. Contents of the invention [0003] The object of the present invention is to provide a special valve for ferrite automatic grouting mold injection that solves the above technical problems. [0004] In order to solve the above-men...
