[0012] The beneficial effects of the present invention are as follows: 1. The present invention provides a lower mold device, and the structural design of the lower mold device fully considers the convenience of mold replacement and maintenance. The simple adjustment system composed of the adjustment column, top block, top column and limit ring and other components allows the operator to easily achieve the rapid replacement of the lower mold body by simply turning the adjustment column.

[0013] 2. The present invention plays a key role in the key link of molding by setting a cooling component.

The reducer uses the Bernoulli equation to optimize the water flow speed and pressure, prolong the residence time of water in the mold, and efficiently take away the heat of the lower mold body; the cooling shell ensures that the heat is stably transferred to the cooling water through the principle of heat transfer, avoiding product deformation, performance degradation and other problems caused by excessive mold temperature, ensuring the intrinsic quality of the product, and improving the reliability and durability of the product.

[0014] 3. The present invention sets a pressing assembly, which works closely with the upper mold device. The pressing block stably presses the edge of the automotive interior product by means of a slide groove that fits with the slide rail of the upper mold assembly to limit the displacement of the product. The resistance rod on the top continuously provides just the right resistance, further consolidating the fixing effect of the pressing block, minimizing the probability of quality problems such as edge deformation or loose fixation, thereby improving the product yield and reducing waste losses.

[0015] 4. The present invention provides a cleaning component to ensure continuous cleaning and efficient operation of the equipment. After the molding is completed, no additional human intervention is required. The pressing block drives the cleaning component to automatically enter the cleaning mode. Through the linkage of the slider, side bag, air bag and other components, as well as the coordination of the top frame, top rod, bump, etc. with the connecting handle, air plug, etc., high-pressure air can be used to automatically remove dust from the outer wall of the upper mold, while helping to separate the product from the mold. This not only saves manual cleaning time and cost, but also prevents dust accumulation from causing adverse effects on subsequent production, ensuring that each molding operation is carried out in a clean environment, further improving product quality.

[0023] The pressing assembly 7 includes a pressing block 72, the top of which is rotatably connected to a resistance rod 71, and the resistance rod 71 is linearly arranged along the outer wall of the pressing block 72, the inner wall of the pressing block 72 is slidably connected to the outer wall of the slide rail 62 through a slide groove 73, and the slide groove 73 is opened in the wall of the pressing block 72, the outer wall of the pressing block 72 is slidably connected to the outer wall of the sliding mold 61, and an air groove 74 is opened in the wall at the bottom of the pressing block 72, and the air groove 74 is linearly arranged along the outer wall of the pressing block 72, the end of the resistance rod 71 away from the pressing block 72 is rotatably connected to the inner wall of the top of the sliding mold 61, and the resistance rod 71 configured on the top of the pressing block 72, as a component for stable pressure application, continuously provides resistance, thereby ensuring that the pressing block 72 can be more stably on the edge of the product during the molding process, reducing quality defects such as edge deformation or loose fixation, and helping to protect the product molding quality.

[0024] The cleaning assembly 8 includes an air bag 85, the outer walls of both sides of the air bag 85 are fixedly connected to the side bags 84 through connecting square tubes, the bottom of the side bags 84 is fixedly connected to the slider 86, the bottom of the air bag 85 is fixedly connected to the air shell 87 through a square tube, the inner wall of the air shell 87 is slidably connected to the connecting handle 89, the inner wall of the connecting handle 89 is plugged with the top frame 81 through a slot 810, and the slot 810 is opened in the wall of the connecting handle 89, the outer wall of the top frame 81 is fixedly connected to the top rod 82, and the top The bottom of the frame 81 is fixedly connected with a protrusion 83, the side of the connecting handle 89 close to the gas shell 87 is fixedly connected with a gas plug 813 through a limiting column 812, and the outer wall of the limiting column 812 is fixedly connected to the side of the connecting handle 89 close to the gas shell 87, the inner wall of the gas shell 87 is fixedly connected with a partition 814, the outer wall of the gas plug 813 is fixedly connected with a top spring 811, and the end of the top spring 811 away from the gas plug 813 is fixedly connected to the inner wall of the gas shell 87 through a fixed disc, and the gas shell The outer wall of 87 is fixedly connected to the inner wall of the pressure block 72, the inner wall of the pressure block 72 is fixedly connected to the top of the side bag 84, the side of the limit column 812 away from the connecting handle 89 is fixedly connected to the outer wall of the air plug 813, the inner wall of the connecting handle 89 contacts the outer wall of the protrusion 83, the top of the top frame 81 is fixedly connected to the outer wall of the sliding mold 61, the bottom of the push rod 82 contacts the outer wall of the fixed frame 10 through the baffle, and the inner wall of the side bag 84 is fixedly connected with a one-way valve 88. Since the bottom of the airbag 85 is connected to the air shell 87, after the air plug 813 is separated from the partition 814, the high-pressure air in the airbag 85 flows into the air groove 74 through the partition 814, and is sprayed to the outer wall of the upper mold by the air groove 74 to remove dust on the surface of the upper mold. At the same time, the high-pressure airflow acts on the outer wall of the automotive interior product to separate the product from the mold. The top spring 811 on the air plug 813 is on standby at any time. After the cleaning process is completed, the air plug 813 is reset to ensure that the equipment cleaning and maintenance system is in an available state.

[0025] Working principle: After the equipment is started, the fixed frame 10, as the basic supporting structure of the entire molding equipment, plays a key role in the smooth progress of subsequent processes and provides a relatively stable basic guarantee. The hydraulic component 11 equipped with the fixed cover 1 on the top responds quickly and starts. According to the preset procedures and parameters, the upper mold device 2 is driven to slide smoothly along the outer wall of the fixed frame 10, gradually accumulating pressure for the molding process that is about to start, so that the initial stage of the molding process can be carried out in an orderly manner, laying the foundation for a series of subsequent operations.

[0026] The core component of the upper mold device 2 is the upper mold assembly 6, which operates under the thrust provided by the hydraulic system, wherein the sliding mold 61 slides down along the inner wall of the fixed frame 10, driving the upper mold body 63 to press down the automotive interior product, and starting the shaping process. When the production process is adjusted and the upper mold body 63 needs to be replaced to adapt to different product specifications, there is a relatively rigorous and convenient operation process: with the help of the driving force of the hydraulic component 11, the upper mold assembly 6 is driven downward until the upper mold body 63 contacts the lower mold device 9, at which time the important node of mold replacement is entered. Then, the two sets of oblique inserts 64 carefully designed on the sliding mold 61 are smoothly slid along the predetermined oblique path, and wait for After the oblique insertion block 64 slides out of the sliding mold 61, the locking state of the sliding mold 61 on the upper mold body 63 is released. Subsequently, the upper mold body 63 is smoothly moved out along the track pre-constructed by the sliding mold 61. The whole process is relatively smooth, with less jamming or deviation. Next, the upper mold body 63 that meets the needs of the new product is pushed to the bottom of the sliding mold 61 along the track, and then the oblique insertion block 64 is passed through the sliding mold 61 along the slot and inserted into the upper mold body 63, and the connection between the sliding mold 61 and the upper mold body 63 is rebuilt. The mutual coordination of this series of operations has improved the flexibility of the equipment and its adaptability to different production tasks to a certain extent, and met diversified production needs.

[0027] The pressing assembly 7 that cooperates with the upper mold device 2 operates synchronously according to the downward rhythm of the upper mold device 2. The pressing block 72 fits and slides with the slide rail 62 of the upper mold assembly 6 by virtue of the slide groove 73 processed on its inner wall to form a linkage structure, which is pressed on the automotive interior product to limit the edge position of the product with appropriate force, thereby preventing displacement during the molding process to a large extent, and ensuring that the product molding accuracy meets the corresponding quality standards. The resistance rod 71 configured on the top of the pressing block 72, as a component for stable pressure application, continuously provides resistance to ensure that the pressing block 72 can be relatively stable on the edge of the product during the molding process, reduce quality defects such as edge deformation or loose fixation, and help protect the molding quality of the product. In addition, the cleaning assembly 8 cleverly integrated inside the pressing block 72 can blow out gas at the moment of pressing to remove some impurities on the surface of the product, provide a relatively smooth surface for the product, reduce subsequent additional processing steps, and improve overall production efficiency.

[0028] The lower mold device 9, as a key collaborative part of the molding process, works closely with the upper mold device 2 to jointly promote the smooth progress of the molding process. When the upper mold body 63 needs to be replaced, the operation process is also convenient: the operator grabs the adjusting column 95, rotates it ninety degrees, and drives the top block 96 to rotate synchronously. When the top block 96 rotates ninety degrees, its protruding part is separated from the contact with the top column 93, and the top column 93 slides down under the action of gravity, disengages from the bottom slot of the lower mold body 91, and releases the position restriction of the lower mold body 91. Then, the lower mold body 91 is smoothly moved out along the track on the mounting seat 92. After the new lower mold body 91 is in place, the adjusting column 95 is rotated ninety degrees again to return the protruding part of the top block 96 to the position, press the top column 93, and force it to reinsert into the bottom slot of the lower mold body 91, and re-lock the position of the lower mold body 91. The limit ring 94 on the adjusting column 95 limits the rotation range of the adjusting column 95 to ensure that the entire replacement process is carried out in an orderly manner.

[0029] In the key link of molding, the cooling component 4 plays an important role as a key subsystem to ensure the stable operation of the mold. The water pump component 42 in the water tank 41 is started according to the principle of fluid mechanics to transport water. The water flows through the outlet pipe 44 to the exquisitely designed reducer 46. The reducer 46 uses a gradual reducer structure based on the Bernoulli equation to regulate the water flow velocity and pressure distribution, extend the residence time of water in the mold, take away the heat of the lower mold body 91, and realize the regulation of the mold temperature, so that the mold is in a better state. When water flows through the cooling shell 47, based on the principle of heat transfer, the heat of the lower mold body 91 is transferred to the cooling water by heat conduction. The heated water returns to the water tank 41 through the connecting pipe 48 and the return pipe 43, completing the cooling cycle, ensuring the stability of the molding process, and avoiding quality problems such as product deformation or performance degradation due to excessive mold temperature, helping each automotive interior product to meet higher production standards.

[0030] After the molding process is completed, the cleaning component 8 automatically switches to the equipment cleaning and maintenance mode. During the molding process, the pressing block 72 synchronously drives the cleaning component 8 downward. When the slider 86 contacts the baffle on the fixing frame 10, it is blocked by the baffle and moves upward along the inner wall of the pressing block 72 to compress the side bag 84, causing the air inside the air bag 85 to enter the air bag 85 through the connecting square tube. Thanks to the one-way valve 88 provided in the connecting square tube, the air can only flow into the air bag 85 in one direction, so as to retain the gas in the air bag 85. At the same time, the top frame 81 moves downward with the upper mold device 2, and its bottom is inserted into the connecting handle 89 and is blocked by the baffle to produce deformation, while the reinforcing plate on the top of the top frame 81 is used to share the stress of the top frame 81. When the molding is completed, the upper mold assembly Position 2 moves upward, driving the top frame 81 upward, and the top rod 82 is free from the baffle, and the top frame 81 is reset by its own elastic potential energy, and the bottom protrusion 83 hits the connecting handle 89, pushing the connecting handle 89 to drive the air plug 813 to separate from the partition 814. Since the bottom of the airbag 85 is connected with the air shell 87, after the air plug 813 separates from the partition 814, the high-pressure air in the airbag 85 flows into the air groove 74 through the partition 814, and is sprayed to the outer wall of the upper mold by the air groove 74 to remove the dust on the surface of the upper mold. At the same time, the high-pressure airflow acts on the outer wall of the automotive interior product to separate the product from the mold. The top spring 811 on the air plug 813 is on standby at any time, and the air plug 813 is reset after the cleaning process is completed to ensure that the equipment cleaning and maintenance system is in an available state and to ensure the continuous and stable operation of the equipment.
