[0002] Interior assembly sound insulation and vibration isolation pads are materials specially used in interior assembly systems to reduce noise and vibration transmission. By absorbing the energy of sound waves and converting them into heat or other forms of energy, the propagation of sound is reduced to achieve a sound insulation effect. By utilizing the elastic properties of the material, the impact energy generated by the vibration of the object is absorbed, effectively reducing the transmission of vibration. Interior assembly sound insulation and vibration isolation pads are usually composited with a variety of materials, including rubber, plastic or other sound-absorbing materials. These materials have excellent damping properties and flexibility, and can effectively adapt to interior assembly systems of different shapes to ensure good sealing and sound insulation. Interior assembly sound insulation and vibration isolation pads are widely used in the interior systems of vehicles such as cars and trains to reduce the noise and vibration generated during driving and enhance the passenger experience. Most interior assembly sound insulation and vibration isolation pads are made of environmentally friendly materials, are non-toxic and odorless, and meet health and safety standards. This not only helps to protect the health of passengers, but also meets the requirements of modern society for environmental protection and sustainable development. The mold for the production of sound insulation and vibration isolation pads is a tool specially designed for the manufacture of sound insulation and vibration isolation pads. The selection of its structure and material is crucial to the production efficiency and product quality of sound insulation and vibration isolation pads. The molds used for the production of sound insulation and vibration isolation pads are usually composed of mold frames, cores, cavities, etc. These components cooperate with each other to process the raw materials into sound insulation and vibration isolation pads with specific shapes and properties through injection molding, molding and other processes.

[0015] The method for using the mold for producing the interior assembly sound insulation and vibration isolation pad includes the following steps: Step 1: During processing, the top module is located in the top module slot and the top module fixing plate is fitted with the fixed mold. The slurry is added to the female mold cavity, and the hydraulic cylinder is extended. The hydraulic cylinder pushes the movable mold limit plate downward along the support limit rod. The movable mold limit plate drives the movable mold below to move downward. The male module moves into the female mold cavity to press the slurry inside the female mold cavity. As the slurry cools down, it is shaped; Step 2: After the blank is formed, the hydraulic cylinder is retracted, and the hydraulic cylinder drives the movable mold limit plate to push downward along the support limit rod, and the movable mold limit plate drives the movable mold below to move downward, the male mold block moves out of the female mold cavity and resets, and the top mold driving screw is adjusted, and the top mold driving screw drives the top mold slide block to move away from the fixed mold. The fixed mold gradually moves downward as the top mold block and the top mold block groove slide and tilt and fit until the fixed mold support seat fits the fixed mold, and as the fixed mold moves downward, the fixedly installed top plate pushes the blank out of the female mold cavity; Step 3: Clean the male module through the cleaning mechanism, adjust the cleaning drive screw, and the cleaning drive screw drives the cleaning slider to slide toward the movable mold. The movable mold drives the cleaning fixed block to move to the bottom of the male module through the linkage of the connecting plate and the electric telescopic cylinder. At the same time, retract the two electric telescopic cylinders to make the sponge pad fit the male module. Reciprocately adjust the cleaning drive screw to make the cleaning fixed block move repeatedly in the left and right directions, so that the surface of the male module is reciprocatedly wiped by the sponge pad to wipe off the material residue adhering to the surface of the male module; Step 4: Clean the fixed mold through the cleaning mechanism, extend the electric telescopic cylinder, and make the cleaning scraper fit with the upper surface of the fixed mold. Since the top plate and the upper surface of the fixed mold are located on the same horizontal plane, the cleaning scraper can scrape and clean the upper surfaces of both at the same time. The cleaning drive screw drives the cleaning slider to move away from the center of the fixed mold, thereby scraping the residual material on the upper surface of the fixed mold into the receiving box.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention cleans the male module through a cleaning mechanism, adjusts the cleaning drive screw rod, and drives the cleaning slider to slide toward the movable mold. The movable mold drives the cleaning fixed block to move to the bottom of the male module through the linkage of the connecting plate and the electric telescopic cylinder, and at the same time contracts the two electric telescopic cylinders to make the sponge pad fit with the male module. The cleaning drive screw rod is reciprocated to make the cleaning fixed block move repeatedly in the left and right directions, so that the surface of the male module is reciprocatedly wiped by the sponge pad to wipe off the material residue adhering to the surface of the male module; the fixed mold is cleaned by the cleaning mechanism, and the electric telescopic cylinder is extended. The electric telescopic cylinder allows the cleaning scraper to fit the upper surface of the fixed mold. Since the top plate and the upper surface of the fixed mold are located on the same horizontal plane, the cleaning scraper can scrape and clean the upper surfaces of both at the same time. The cleaning drive screw drives the cleaning slider to move away from the center of the fixed mold, thereby scraping the residual material on the upper surface of the fixed mold into the material receiving box. This solves the problem that when the mold is produced and the molding material is taken out after a molding operation is completed, the staff needs to manually clean the inside of the mold. The work intensity is low, but the staff needs to stay in the mold working area waiting for the molding to be completed, which consumes labor costs during production.

[0017] 2. After the blank is formed, the hydraulic cylinder is contracted, and the hydraulic cylinder drives the movable mold limit plate to push downward along the support limit rod. The movable mold limit plate drives the movable mold below to move downward, the male mold block moves out of the female mold cavity and resets, and the top mold driving screw is adjusted. The top mold driving screw drives the top mold slide block to move away from the fixed mold. The fixed mold gradually moves downward as the top mold block slides and tilts with the top mold block groove until the fixed mold support seat fits with the fixed mold. As the fixed mold moves downward, the fixedly installed top plate pushes the blank out of the female mold cavity. BRIEF DESCRIPTION OF THE DRAWINGS

The cleaning drive screw (20) is reciprocated to make the cleaning fixed block (22) move repeatedly in the left and right directions, so that the surface of the male module (10) is reciprocatedly wiped by the sponge pad (29) to wipe off the material residue adhering to the surface of the male module (10); Step 4: The fixed mold (8) is cleaned by the cleaning mechanism (14), and the electric telescopic cylinder (28) is extended to allow the cleaning scraper (30) to fit the upper surface of the fixed mold (8). Since the top plate (11) and the upper surface of the fixed mold (8) are located on the same horizontal plane, the cleaning scraper (30) can scrape and clean the upper surfaces of both at the same time. The cleaning drive screw (20) drives the cleaning slider (21) to move away from the center of the fixed mold (8), thereby scraping the material remaining on the upper surface of the fixed mold (8) into the receiving box (16).
