Abstract:
Extrusion equipment for two-part reactive curing materials, comprising:a base plate having a grip and a lever in front of the grip on a bottom face of the base plate, the base plate holding tubes of two-part reactive materials with their respective mouths directed forward on a top face of the base plate;a pushing plate having a rear end pivotably fixed to a rear end of the base plate to allow a vertical inclination on the base plate and to sandwich the bodies of the tubes with the base plate; anda pushing plate-inclining means which transmits a pulling force of the lever to the pushing plate as a force to incline the pushing plate downward,wherein the pushing plate-inclining means has a sliding shaft which is pierced through the base plate to have its top end connected to the leading end of the pushing plate with play in a back-and-forth direction and a push-down plate and a stopper plate through which the sliding shaft pierces slidably below the base plate;the push-down plate is pushed upward by a first spring into a sliding position to allow the sliding shaft to slide before the lever is pulled, inclined downward with its one end pushed down by the lever when the lever is pulled so to engage with the sliding shaft to prevent the sliding shaft from sliding and pushed downward involving the sliding shaft against the first spring, and returned to the sliding position by the pushing force of the first spring when the pulling force of the lever is released; andthe stopper plate is pushed upward by a second spring to incline with its one end as a fulcrum into an engaging position so as to engage with the sliding shaft before the lever is pulled to prevent the sliding shaft from sliding, inclined downward into a sliding position to allow the sliding shaft to slide against the second spring as the sliding shaft slides downward when the lever is pulled, and returned to the engaging position by the pushing force of the second spring when the pulling force of the lever is released.
