Description

Technical Field

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

[0002] Vulcanizers are mainly used to simulate the vulcanization conditions in actual production. By precisely controlling parameters such as temperature, pressure, and time, they continuously measure the physical property changes of rubber compounds during vulcanization, such as shear modulus, torque, etc., so as to evaluate the vulcanization state of the rubber compounds. This provides an important basis for the quality control, formula optimization, and production process improvement of rubber products. In the process of using existing vulcanizers, after detecting a sample, it is necessary to manually clean the mold cavity on the lower mold and the surface of the upper mold before detecting the next sample, so as to avoid the residues of the previous detected sample affecting the subsequent detected sample. After cleaning, the detection is carried out. Such a detection process makes the detection work efficiency relatively low when detecting multiple samples. Summary of the Invention

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, with the following advantages:

[0037] 1. When conducting sample detection, by replacing the lower mold, the trouble of cleaning the lower mold during the entire detection process can be well avoided. At the same time, when the upper mold moves upward, automatic cleaning of the surface of the upper mold can be achieved without the need for staff to clean. The installation and disassembly of the lower mold are very convenient and fast, greatly improving the work efficiency of sample detection.

[0038] 2. When conducting sample detection, place the lower mold on the fixed carrier seat so that the plane reference plate contacts the reference strip plate, and then drive the upper mold to move downward. As the upper mold moves downward, it will drive the carrier plate strip to move. Under the action of the carrier plate strip, the movable carrier block will be driven to move. As the movable carrier block moves, the limit contact strip will be driven to contact the lower mold to achieve the limit of one end of the lower mold. During the movement of the movable carrier block, the push disk will drive the cooperation connection plate to move. Under the action of the cooperation connection plate, the push top limit strip will be driven to move. During the movement of the push top limit strip, it can not only push the lower mold to the accurate working position, but also limit and fix the lower mold from both sides.

[0039] 3. In addition, after the lower mold is positioned, as the upper mold moves downward, the connecting support plate will drive the first annular plate frame to move downward. Then, under the action of the first annular plate frame, the second annular plate frame can be driven to move downward. As the second annular plate frame moves downward, it will drive the locking plug to be inserted into the stable channel to fix the lower mold, which can prevent the lower mold from being driven to move upward together with the upper mold during the upward movement of the upper mold after the detection is completed. As the upper mold moves upward and resets, the carrier plate strip will also reset. Then, under the action of the scraping strip, the surface of the upper mold can be cleaned.

In addition, both ends of the return spring 63 are respectively fixed on the reference carrier block 171 and the pushing and limiting strip 6.

[0060] As Figure 1 、 Figure 9 As Figure 10 shown, the lower die fixing mechanism includes a first annular plate frame 7 and a second annular plate frame 8.

Both ends of the second support spring 82 are respectively fixed on the second annular plate frame 8 and the cooperating carrier 44.

[0062] A rubber detection method includes the following steps:

[0063] Step 1: Placement of the lower mold 2: Make the plane reference plate 21 on the lower mold 2 contact the reference strip 17, and place the lower mold 2 on the fixed carrier 15;

[0064] Step 2: Placement of the sample: Place the sample in the mold cavity on the lower mold 2;

[0065] Step 3: Position adjustment and limitation of the lower mold 2: The upper mold 12 moves downward to achieve the position adjustment and limitation of the lower mold 2 through the limit contact strip 46 and the push - top limit strip 6;

[0066] Step 4: Mold closing: The movable carrier 11 drives the upper mold 12 to move downward to close with the lower mold 2;

[0067] Step 5: Detection of the sample: Start the vulcanization instrument body 1 to detect the sample.

[0068] When detecting a sample, the flat 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, and the sample is placed in the cavity on the lower mold 2. The vulcanizer body 1 is started to move the movable carrier 11 downward, and then drive the upper mold 12 downward. The movable carrier 11 is driven by a driving mechanism in the prior art to move. As the movable carrier 11 moves downward, it will drive the bearing plate strip 3 downward. As the bearing plate strip 3 moves downward, under the cooperation of the mating post 35 and the driving channel 183, it will drive the bearing plate strip 3 to move in the direction of the driving carrier 18. As the bearing plate strip 3 moves, it will also drive the movable bearing block 4 to move. The movable bearing block 4 will drive the limit contact strip 46 to move until the limit contact strip 46 contacts the lower mold 2 to limit the lower mold 2. During the movement of the movable bearing block 4, the push plate 43 will contact the mating connection plate 5. In this way, under the action of the movable bearing block 4, it will drive the mating connection plate 5 to move. As the mating connection plate 5 moves, under the action of the movable connection rod 53, it will drive the push limit strip 6 to move in the direction of the lower mold 2. In this way, under the action of the push limit strip 6, it can push the lower mold 2 to move together to move it to the correct working position, so that the stable channel 22 is aligned with the locking plug 84, and finally play a role in limiting the lower mold 2 from both sides. When the lower mold 2 moves to the correct working position, at this time the mating post 35 also moves into the locking channel 19, so as to ensure that the bearing plate strip 3 no longer moves in the direction of the driving carrier 18. As the mating plate frame 33 continues to move, the connecting bearing plate 36 will push the mating top plate 72 downward, and then drive the first annular plate frame 7 downward. As the first annular plate frame 7 moves downward, it will also drive the second annular plate frame 8 downward. As the second annular plate frame 8 moves downward, under the action of the mating driving rod 83, it will push the locking plug 84 to move so that the locking plug 84 is inserted into the stable channel 22 to fix the lower mold 2 and prevent the upper mold 12 from driving the lower mold 2 upward when moving upward. After the detection is completed, as the upper mold 12 moves upward, it will unlock the lower mold 2 and at the same time drive the bearing plate strip 3 to move in the reverse direction. In this way, under the action of the scraping strip 31, the surface of the upper mold 12 can be cleaned. And since the lower mold 2 is in the unlocked state, it can be quickly removed and replaced, which is convenient for the detection of the next sample.

[0069] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
