Description

Technical Field

[0001] The invention belongs to the technical field of rubber injection, and in particular relates to a vulcanizing machine. Background Art

[0002] Wind wheel sleeves (bushi) and automobile bushings are widely used in air conditioners, automobile shock absorption systems, etc. They are the core components of equipment shock absorption and noise reduction. Wind wheel sleeves / bushings are products made of metal and synthetic rubber after mixing and processing, and are vulcanized by hydraulic vulcanizers using extrusion mold injection molding. The existing vulcanizing machines require a certain reaction time for vulcanization. In order to improve efficiency, the tonnage and number of mold cavities can only be increased, which indirectly leads to uneven template pressure and temperature, affecting product performance. The increase in mold cavities also increases the flow channel distance, causing rubber waste. In addition, the sulfide gas generated during the reaction process poses a huge health hazard to operators. Therefore, the industry has been exploring the realization of automation processes, but the traditional vulcanizing press structure has created many obstacles to the realization of automation, so the automation of the process must be realized through a new structure.

[0081] When the present invention is put into use, the metal ring 102 is loaded by two loading mechanisms, and the metal ring 102 is placed on the lower mold body 75, and then the filter element 108 is loaded. The turntable 50 moves step by step, and the injection mold carrying the metal ring 102 and the filter element 108 is molded together, and then enters the residual removal station. At this time, the extraction member 64 enters the extraction groove 67, and then the residual removal cylinder 66 is pulled out to cut the material. Then the turntable 50 moves further, and the inner push cylinder 69 pushes the extraction member 64 in, so that the output port of the injection mechanism is aligned with the connecting port 65. Then, the injection mechanism controls the vertical plate to move down to achieve docking and then inject material. The turntable 50 rotates further, and vulcanization is completed in the process. Then it rotates to the mold separation station, and the first push rod 84 works. At this time, the first matching part 74 is on the mold separation guide rail 80. After the top pressure block 81 is separated from the lower mold assembly 73, the first matching part 74 moves down along the mold separation guide rail 80 to achieve the separation of the upper mold assembly 60 and the lower mold assembly 73. Then, the top mold cylinder 91 pushes the ejector pin 92 upward to eject the finished product. Then, the third picking mechanism picks up the finished product and puts it on the conveyor belt 117.

[0082] Compared with the prior art, the advantages of the present invention are: the present invention has a simple structure, the entire vulcanization process is automatic, and is realized by the rotation of the multi-station turntable 50, so that the state of the lower mold assembly 73 at different stations can be switched, and each station is closely coordinated to increase work efficiency. At the same time, the vulcanization time is guaranteed, the qualified rate of the product is increased, and it has energy-saving and high-efficiency effects.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
