Specifically, the working process or working principle of the Marshall test piece mold stripping device is as follows: when in use, firstly, a die with a test piece inside is placed at the ejection disc 2, then the ejection disc 2 drives the placed die to move upwards until the die enters the ejection frame 3, the ejection disc 2 continues to move upwards, so that the test piece is ejected from the die, the ejected test piece is positioned at the top of the ejection frame 3, at the moment, the controller 4 controls the hydraulic telescopic rod 10 to start, the hydraulic telescopic rod 10 drives the C-shaped connecting frame 6 to move downwards with the movable box 11 arranged at the bottom of the C-shaped connecting frame, in the process of downwards moving the movable box 11, the L-shaped connecting frame 13 is driven to synchronously move, when the L-shaped connecting frame 13 moves downwards along with the movable box 11, the pressing plate 30 can be driven to move downwards in the fixed box 26, the air bag 29 at the bottom of the L-shaped connecting frame is extruded, the air bag 29 is extruded and deformed, and gas in the air bag is continuously discharged into the movable box 11 through the gas pipe 27, with the continuous increase of the gas entering the movable box 11, the sealing plate 31 can be driven to move towards one side of the clamping plate 33 in the movable box 11, the number of the movable boxes 11 is two, the two movable boxes 11 are symmetrically arranged, so that the connecting rod 32 and the clamping plate 33 are driven to move towards each other in the moving process of the sealing plate 31, that is, the distance between the two clamping plates 33 is continuously reduced along with the continuous descending of the movable box 11, finally when the test piece at the top of the ejection frame 3 is reached, the test piece is clamped between the two clamping plates 33, after the test piece is clamped, the movable box 11 is driven to move towards one side of the conveying frame 16 in the clamping groove 8 through the movable machine head 9, when the movable machine head 9 moves to the innermost end of the clamping groove 8, the touch switch 40 is touched, at the moment, the touch switch 40 opens the electromagnetic valve 39, under the reset action of the first reset spring 34, the sealing plate 31 is driven to move towards the direction of the L-shaped connecting frame 13 in the movable box 11, so that the two clamping plates 33 move towards opposite directions, a test piece clamped between the two clamping plates 33 automatically falls onto the top surface of the conveying frame 16, and finally falls into the collecting barrel 18 for uniform collection along with the conveying of the conveying frame 16.
When the test piece enters the interior of the collection tube 18 along with the conveying of the conveying frame 16, the test piece firstly falls downwards along the liquid storage tube 19, and as the ether and acetone solution are injected into the interior of the liquid storage tube 19, the sponge block 41 is fixedly arranged in the liquid storage tube 19, the sponge block 41 absorbs the solution in the liquid storage tube 19, and after the test piece enters the interior of the liquid storage tube 19, the outer surface of the test piece contacts with the sponge block 41, so that the solution absorbed in the sponge block 41 is wiped on the outer surface of the test piece, the removal of the release agent on the outer surface of the test piece is facilitated, and the influence of the release agent on the outer surface of the test piece on the tested data is avoided in the subsequent testing process.
In the process of opening the electromagnetic valve 39, the sealing plates 31 inside the two moving boxes 11 are driven by the first return spring 34 to move towards the direction of the L-shaped connecting frame 13, at this time, air on one side of the first return spring 34 of the sealing plate 31 can be discharged into the exhaust pipe 25 through the air outlet pipe 38, enter the inside of the water diversion plate 24 through the exhaust pipe 25, enter the inside of each partition plate 23 through the water diversion plate 24 respectively, and finally are sprayed outwards through the air outlet holes 47 formed in two sides of each partition plate 23, so that on one hand, the solution on the outer surface of a test piece can be dried, on the other hand, the circulation of the air inside the collecting cylinder 18 can be accelerated, and the drying effect of the solution on the outer surface of the test piece is improved again.
When a test piece is clamped above the conveying frame 16 and put down, the two movable boxes 11 can return to the upper part of the ejection frame 3 again under the drive of the movable machine head 9, and the next clamping and conveying operation is performed.
Along with the inside that the test piece continuously enters into the collection tube 18, and be located the top of sealing disk 42, the continuous increase of gravity that sealing disk 42 bore can be at the inside downwardly moving of collection tube 18, the inside of communicating pipe 44 is impressed with the air of its below in the in-process that removes, and enter into the inside of air distribution pipe 45, finally enter into the inside of reservoir 19 through air supply pipe 46, after the inside of reservoir 19 is entered into to the air, a large amount of bubbles can be produced to the solution inside reservoir 19, on the one hand can improve the mixing effect between ether and the acetone solution, on the other hand also can make the mixed solution inside the reservoir 19 produce undulant easier by sponge piece 41 absorption, improve the cleaning effect to test piece surface release agent.
It should be noted that, the hydraulic telescopic rod 10 is a device or apparatus existing in the prior art, or a device or apparatus that can be implemented in the prior art, and the power supply, the specific composition and the principle thereof are clear to those skilled in the art, so they will not be described in detail.
