Technical Field

[0001] This utility model relates to the field of general mechanical equipment manufacturing technology, and in particular to a quick mold changing mechanism for an automotive seat ring production line. Background Technology

[0002] In the production of automotive seats, circular production lines are often used to improve production efficiency and flexibility. However, changing molds is a frequent and time-consuming operation in the production of seat foam. To separate production and mold changing, the mold trolley of the automotive seat circular production line is designed with a quick-detachable structure.

[0003] However, once the mold frame trolley is unloaded from the circular production line, the overall weight of the mold frame is too heavy, making it impossible to open and close the mold frame manually. This makes opening and closing the mold frame extremely inconvenient, affecting the efficiency of mold changing and increasing the labor intensity and safety risks for operators. Utility Model Content

[0004] The purpose of this utility model is to provide a quick mold changing mechanism for a circular production line for automobile seats. This mechanism solves the problem that when the mold frame trolley is unloaded from the circular production line, the overall weight of the mold frame is too heavy, making it impossible to open and close the mold frame manually. This makes opening and closing the mold frame extremely inconvenient, affecting the mold changing efficiency and increasing the labor intensity and safety risks for operators.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1 to 5 This utility model provides a quick mold changing mechanism for a circular production line of automobile seats. The quick mold changing mechanism for a circular production line of automobile seats includes a main frame 101, two electric hoist components 102, two square mounting frames 103, two mold opening cylinder components, four safety pin assemblies, and two lower mold frame support assemblies. Two mold changing stations 104 are arranged side by side on the main frame 101. A crossbeam 105 is provided at the middle of the top of each mold changing station 104. The electric hoist components 102 are slidably installed on the crossbeam 105. A sling 106 is provided at the output end of the electric hoist components 102.

[0021] The main frame 101 is also provided with two square mounting frames 103, which are located in the middle of the corresponding mold changing station 104. Each square mounting frame 103 is provided with a mold opening cylinder component, and the output end of the mold opening cylinder component is hinged with a roller cover 107. Each square mounting frame 103 is provided with inclined arms 108 on both sides, and each inclined arm 108 is provided with a safety pin assembly through a mounting plate 109. Each mold changing station 104 is also provided with a lower mold frame support assembly.

[0022] In this embodiment, after the mold frame trolley is pushed into the mold changing station 104, the sling 106 is threaded onto the lower roller of the mold frame on the trolley. The mold frame is then leveled using the electric hoist component 102 (the electric hoist component 102 is a common lifting device in the prior art, so the specific structure of the electric hoist component 102 will not be described in detail in this technical solution). The lower mold frame support assembly supports the lower mold frame roller, the mold fixing screws inside the mold frame are loosened, and the opening and closing of the upper mold frame is controlled by the mold opening cylinder component and the roller cover 107. The upper mold frame is stabilized by the safety pin assembly. After the mold in the mold frame is replaced by a forklift, the upper mold frame is closed again by the mold opening cylinder component and the roller cover 107, and the fixing screws are tightened to complete the replacement of the mold in the mold frame. By adopting this technical solution, manual operation is reduced, mold changing efficiency is improved, and labor intensity and safety risks are reduced during the replacement of the mold in the mold frame.

[0023] The mold frame trolley of the car seat circular production line and the mold used to produce car seat foam mentioned in this technical solution are existing technologies, and therefore are not described in detail in this technical solution.

[0024] Furthermore, each of the mold-opening cylinder components includes two mounting brackets 110 and two cylinder bodies 111. The two mounting brackets 110 are mounted on the upper surface of the square mounting frame 103. Each mounting bracket 110 is provided with a cylinder body 111. Each cylinder body 111 is arranged in an inclined structure. The output end of each cylinder body 111 is hinged to the roller cover 107.

[0025] In this embodiment, since the existing automotive seat circular production line has two mold frames installed on the mold frame trolley, each mold changing station 104 is provided with two mounting brackets 110 and two cylinder bodies 111. Each cylinder body 111 is used for opening and closing the upper mold frame of the corresponding mold frame, thereby improving the mold changing efficiency.

[0026] Furthermore, each cylinder body 111 is provided with a hinge joint 112 at its output end, and each roller cover 107 is fixedly provided with a connecting plate 113 on its exterior. The connecting plate 113 is installed at the corresponding hinge joint 112 by a fixing pin 114.

[0027] In this embodiment, the roller cover 107 is hingedly installed at the output end of the cylinder body 111 by means of the hinge joint 112, the connecting plate 113 and the fixing pin 114.

[0028] Furthermore, each of the safety pin assemblies includes a mounting base 115 and a pneumatic safety pin 116. The mounting base 115 is mounted on one end of each mounting plate 109 away from the corresponding inclined arm 108, and the pneumatic safety pin 116 is provided on each mounting base 115.

[0029] In this embodiment, the pneumatic safety pin 116 is set by the mounting base 115, and the pneumatic safety pin 116 supports the upper mold frame after it is opened, thereby ensuring that the upper mold frame will not fall and hit the operator.

[0030] Furthermore, each of the lower mold support components consists of two support frames 117, and a support arc plate 118 is fixedly provided at the top of each support frame 117.

[0031] In this embodiment, since the existing automotive seat circular production line has two mold frames installed on the mold frame trolley, this technical solution uses two support frames 117 to support the corresponding lower mold frame rollers. Furthermore, the structure is more stable when the lower mold frame rollers are supported by the support arc plate 118.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
