By means of the polyurethane elastomer product casting technology, the problems that in an existing mold preparation process, a demolding agentis usually sprayed onto the inner wall of a mold cavity with the help of a spraying gun; because the volume of the spraying gun head is larger, positions with smaller space in the cavity cannot be sprayed by the spraying gun head, and thus the situation that the sprayed surface is not complete is caused; because cavity structures of different molds are different, in the spraying process, staff need to adjust their own spraying action so that the staff can cope with the cavity inner wall in different positions; and in addition, the circumstances of surplus spraying or inadequate spraying can occur in part of the inner wall, and thus the situation that the thickness of the sprayed layer is different is caused can be solved.

Efficient cleaning equipment for traffic roadblock

The invention relates to the technical field of cleaning equipment for traffic roadblocks, in particular to efficient cleaning equipment for a traffic roadblock. The position of a upper cleaning assembly is adjusted through a lead screw assembly such that the upper cleaning assembly is attached to the roadblock, meanwhile, a reciprocating assembly based on disc rotation is adopted for driving a supporting base to rotate in a reciprocating mode, the roadblock moves relative to the upper cleaning assembly such that rapid and convenient cleaning work is completed,. The upper cleaning assembly adopts a servo motor to drive a cylindrical cam to rotate, and a rocker drives a cleaning plate crank through matching of a clamping block and a groove channel of the cylindrical cam, so that the angle of a cleaning plate is adjusted so as to be suitable for cone design of the roadblock; the upper cleaning assembly is also provided with a spray head for spraying and washing; a lower reciprocating assembly is arranged to serve as power for pumping and discharging the cleaning liquid to the spraying assembly, a crank throw rotates along with the lower supporting shaft while the lower supporting shaft rotates, a piston plate is driven by a sleeve and a piston rod to move left and right, the two one-way valves are matched, automatic pumping and discharging of the cleaning liquid are achieved, andthe cleaning liquid is injected into the spraying assembly.
