Flow channel clamp

Abstract

The invention relates to a flow channel clamp for taking an injection molding product out of a flow channel by a manipulator. A sensor side clamp claw, a clamp claw and a clamp substrate are movably connected; a sensor is arranged on a fixing bracket; two pistons are arranged in the cavity of the clamp substrate; the cambered surfaces of the two pistons are contacted with the two clamp claws; return springs are sleeved on inner shafts of two clamp claw holes; an air inlet joint is arranged at one end of the clamp substrate; the clamping position of the sensor side clamp claw is provided with an induction tongue connected with the sensor; a spring is arranged in the sensor side clamp claw and arranged between the induction tongue and an inductor; one end of the clamp substrate is provided with a limiting boss; and the clamping claw is provided with a limiting surface. When the flow channel clamp is used, an air pressure in the substrate pushes the two clamp claws through the piston so as to realize gripping; and when the clamp clamps the flow channel, the induction tongue approaches the inductor, so that the inductor starts working and sends a confirmation signal to the manipulator. The clamp has the advantages of small size, large clamping force, convenience for installation under the condition of small space and taking various flow channels at positions which can be clamped out, capability of giving feedback information to the manipulator and realization of confirmation of the existence and absence of flow channel clamping.

Description

technical field [0001] The invention relates to a fixture in the field of mechanical manufacturing, in particular to a clamping device for taking out flow channels of injection molded products by manipulators. Background technique [0002] At present, with the improvement of factory automation, more and more take-out manipulators are used in injection molding. However, the requirements for compact mold structure and saving raw materials are getting higher and higher, so that the parts that can be clamped by the flow channel are getting smaller and smaller. This increases the difficulty of taking out the runner, which affects the automatic production effect. However, the existing runner fixtures are relatively large, and the sensor for realizing whether the runner is clamped or not is not integrated with the fixture body, which cannot meet the needs of automation. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the pre...
