Manufacturing process and manufacturing equipment of rubber vibration isolation pad

Abstract

The invention discloses a manufacturing process for a rubber vibration isolator. The process comprises the following steps: 1, taking a thin steel plate and punching a plurality of through holes in the surface of the thin steel plate; 2, horizontally placing the thin steel plate in an injection molding cavity and integratedly forming vibration isolators at two sides of the thin steel plate through vulcanization by using a direct vulcanization method; and 3, carrying out die opening to obtain a finished product. The invention also discloses manufacturing equipment used in the manufacturing process. The manufacturing equipment comprises an upper die, a lower die and an intermediate die arranged between the upper die and the lower die. The upper die, the lower die and the intermediate die together form the injection molding cavity for the rubber vibration isolators, and the injection molding cavity is characterized in that a horizontal thin steel plate position is in the injection molding cavity. According to the invention, multiple layers of vibration isolation are adopted for reinforcement, vibration damping rubber is selected and utilized, passive vibration attenuation is carried out by using the intermediate thin steel plate, the rubber vibration isolators are integratedly formed through punching of the thin steel plate and the direct vulcanization method without a bonding agent, and a multidirectional die-opening method is used to realize die-opening of the product; therefore, a process for intersecting formation of vibration isolation grooves on the product is guaranteed, the advantages of high production efficiency and environmental protection are obtained, and the prepared product is durable and has good vibration damping and vibration isolating effects.

Description

technical field [0001] The invention relates to the technical field of vibration-damping equipment manufacturing, in particular to a manufacturing process of a rubber vibration-isolating pad and manufacturing equipment for implementing the process. Background technique [0002] Some fixed installations often generate vibration and noise during operation, especially some equipment installed in buildings and other buildings, such as transformers, central air conditioners, water pumps, machine tools and other mechanical equipment, need to take corresponding vibration reduction measures. [0003] The current vibration reduction methods are generally achieved by gradually absorbing and attenuating vibration or noise. For example, the existing vibration isolation pads are basically provided with connecting parts such as thin Steel plates are connected and bonded firmly with adhesives.

Problems solved by technology

[0003] The current vibration reduction methods are generally achieved by gradually absorbing and attenuating vibration or noise. For example, the existing vibration isolation pads are basically provided with connecting parts such as thin Steel plates are connected and bonded firmly with adhesives. This manufacturing method has been used in large quantities in China to form a directional pattern. However, this manufacturing method has certain shortcomings, such as vibration isolation pads bonded by adhesives. During use or long-term use, the adhesive will fail, resulting in misalignment of the vibration damping plates between each other, which will reduce the vibration isolation effect and fail to achieve the expected vibration isolation effect. At this time, it is necessary to replace the vibration isolation Pads increase maintenance costs, and the replacement process is cumbersome; in addition, the adhesives used are not environmentally friendly and harmful to human health
