Abstract

The invention discloses a lever-valve needle single nozzle which comprises a feed nozzle cap and a side cylinder support body, wherein a feed opening is formed in the center of the feed nozzle cap; the side cylinder support body is connected to the lower end of the feed nozzle cap; the feed opening of the side cylinder support body corresponds to the feed passage of the side cylinder support body; a switching-over body is arranged at the lower end of the side cylinder support body; the feed passage is arranged in the middle of the switching-over body longitudinally, and is inclined; heaters are clung to the outer sides of the side cylinder support body and the switching-over body; the upper end of the switching-over body is communicated with the feed passage of the side cylinder support body; the lower end of the switching-over body is communicated with the central hole of a spray nozzle main body. The lever-valve needle single nozzle has the advantages that the structure is simple; the production cost is low; meanwhile, a cylinder body is far away from thermal source of a hot runner, so as to efficiently reduce the overheating phenomenon at the periphery of a seal ring, prolong the service life of the seal ring, and further prolong the service life of the cylinder; moreover, the mobile strength of a valve needle is effectively enhanced through a lever, so that the high injection pressure requirement of production activity is met effectively.

Description

technical field [0001] The invention relates to a lever valve needle single nozzle, in particular to a lever valve needle single nozzle in the injection molding industry. Background technique [0002] The current valve needle single nozzles are all cylinders or oil cylinders and single nozzles as a whole, so the sealing ring is easily damaged in a high temperature environment, which greatly reduces the service life of the cylinder. Contents of the invention [0003] Aiming at the disadvantages of the existing valve needle single mouth, the invention provides a novel lever valve needle single mouth. [0004] In order to achieve the above object, the measures taken by the present invention [0005] A lever valve needle single nozzle, including a feed nozzle cap and a side cylinder support body, the center of the feed nozzle cap is provided with a feed hole, the lower end of the feed nozzle cap is connected with a side cylinder support body, and the feed nozzle The feeding ...
