Description

Technical Field

[0001] The invention relates to the technical field of vulcanizers, in particular to a vulcanizer for rubber testing and a detection method thereof. Background Art

[0002] The vulcanizer is mainly used to simulate the vulcanization conditions in actual production. By accurately controlling parameters such as temperature, pressure and time, the physical property changes of the rubber during the vulcanization process, such as shear modulus and torque, are continuously measured to evaluate the vulcanization state of the rubber. This provides an important basis for quality control, formula optimization and production process improvement of rubber products. In the use of the existing vulcanizer, after the sample is tested, the cavity on the lower mold and the surface of the upper mold need to be manually cleaned before the next sample can be tested to avoid the residue of the previous test sample affecting the subsequent test sample. The test is carried out after cleaning. Such a test process makes the test efficiency relatively low when multiple samples are tested. Summary of the invention

As the second annular plate frame moves downward, it will drive the locking plug plate to be inserted into the stable channel to fix the lower mold. This can avoid the upper mold driving the lower mold to move up with it during the upward movement after the inspection is completed. As the upper mold moves up and resets, the bearing strips will also be reset, and then the surface of the upper mold can be cleaned under the action of the scraper. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] A rubber detection method comprises the following steps: Step 1: Placing the lower mold 2: The plane reference plate 21 on the lower mold 2 is brought into contact with the reference strip plate 17, and the lower mold 2 is placed on the fixed carrier 15; Step 2: Sample placement: Place the sample in the mold cavity on the lower mold 2; Step 3: Position adjustment and limit of the lower mold 2: The upper mold 12 moves downward to achieve position adjustment and limit of the lower mold 2 through the limit contact strip 46 and the push-up limit strip 6; Step 4: mold closing: the movable carrier 11 drives the upper mold 12 to move downward and close together with the lower mold 2; Step 5: Sample detection: Start the vulcanizer body 1 to detect the sample.

[0039] When testing the sample, the plane reference plate 21 on the lower mold 2 is brought into contact with the reference strip 17, the lower mold 2 is placed on the fixed carrier 15, the sample is placed in the mold cavity on the lower mold 2, the vulcanizer body 1 is started to move the movable carrier 11 downward, thereby driving the upper mold 12 to move downward, and the movable carrier 11 is driven to move by the driving mechanism under the prior art. As the movable carrier 11 moves downward, it will drive the bearing strip 3 to move downward. As the bearing strip 3 moves downward, the matching column 35 and the driving channel 183 will drive the bearing strip 3 to move in the direction of the driving carrier 18. The movable bearing block 4 moves with the movement of the bearing plate strip 3, and the movable bearing block 4 drives the limit contact strip 46 to move, and finally makes the limit contact strip 46 contact with the lower mold 2, so as to limit the lower mold 2.

The lower mold 2 is moved to the correct working point, so that the stabilizing channel 22 is aligned with the locking plug plate 84, and finally the lower mold 2 is limited from both sides. When the lower mold 2 moves to the correct working point, the matching column 35 is also moved into the locking channel 19 at this time, so that the bearing strip 3 is no longer moved in the direction of the driving carrier 18. As the matching plate frame 33 continues to move, the connecting plate 36 will push the matching top plate 72 to move downward, thereby driving the first annular plate frame 7 to move downward. As the first annular plate frame 7 moves downward, it will also drive the second annular plate frame 8 downward. Movement, as the second annular plate frame 8 moves downward, the locking plug plate 84 will be pushed to move under the action of the cooperative driving rod 83 so that the locking plug plate 84 is inserted into the stabilizing channel 22, thereby fixing the lower mold 2 and preventing the upper mold 12 from moving upward when the upper mold 12 moves upward. After the inspection is completed, as the upper mold 12 moves upward, the lower mold 2 will be unlocked and the supporting strip 3 will move in the opposite direction. In this way, the surface of the upper mold 12 can be cleaned under the action of the scraper strip 31. Since the lower mold 2 is in an unlocked state, it can be quickly removed and replaced, which is convenient for the inspection of the next sample.
