Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a mold assembly and box closing device. Background Technology

[0002] In modern industrial production, molds are widely used in various fields, such as automobiles, electronics, and machinery. The structure and precision of molds directly affect product quality and production efficiency. The mold manufacturing process typically includes multiple stages such as design, processing, assembly, and debugging, among which mold assembly and box fitting is one of the key steps in the mold manufacturing process.

[0003] In related technologies, there are various mold fitting and box assembly devices or methods. Traditional mold fitting and box assembly devices are operated manually, with workers placing the sand box and box cover in designated positions and then performing the box assembly operation.

[0029] like Figures 1 to 7 The mold assembly and box assembly device shown includes:

[0030] The receiving mechanism 10 includes a first receiving bracket 11 and a second receiving bracket 12 arranged in parallel perpendicular to the conveying direction. The first receiving bracket 11 and the second receiving bracket 12 are respectively used to receive and convey the sand box and the box cover. The sand box and the box cover are recessed at both ends along the conveying direction to form two positioning clamping holes.

[0031] The clamping mechanism 20 includes a top frame 21, a movable support 22, clamping arms 23, and positioning claws 24. The top frame 21 is fixedly installed on the top of the receiving mechanism 10. The movable support 22 is movably connected to the top frame 21. A pair of clamping arms 23 are provided. The two clamping arms 23 are arranged opposite each other along the direction of sand box conveying, and one end is connected to the movable support 22. The other end of each clamping arm 23 is provided with two positioning claws 24. The positioning claws 24 are provided with positioning clamping holes on the same end face of the sand box or box cover.

[0032] This invention significantly improves automation through the coordinated action of the receiving mechanism 10 and the clamping mechanism 20. It can quickly complete the gripping, conveying, alignment, and assembly of sand boxes and lids, shortening the mold assembly and assembly time and meeting the needs of large-scale production. By precisely engaging the positioning claws 24 with the positioning holes on the sand boxes and lids, accurate alignment of the sand boxes and lids is ensured, effectively improving the sealing performance of the molds and product quality, and reducing product defects and mold damage caused by inaccurate alignment. In addition, by adjusting the positions of the clamping arms 23 and the positioning claws 24, it can adapt to sand boxes and lids of different specifications and sizes, realizing mold assembly and assembly operations for various molds, with a wide range of applications.

[0033] Specifically, the first receiving bracket 11 and the second receiving bracket 12 are arranged side by side and perpendicular to the conveying direction, providing a stable placement and conveying platform for the sand box and the box cover. This ensures that the sand box and the box cover can maintain a relatively stable positional relationship during the conveying process, and also facilitates subsequent clamping and alignment operations. The two end faces of the sand box and the box cover are recessed to form positioning clamping holes, which provide precise gripping points for the positioning claws 24 of the clamping mechanism 20, ensuring the accuracy and stability of the clamping.

[0034] The top frame 21, as the main supporting component of the clamping mechanism 20, is fixed to the top of the receiving mechanism 10, providing an installation base for components such as the movable bracket 22, clamping arm 23, and positioning jaw 24, ensuring the structural stability and rigidity of the entire clamping system, enabling it to maintain precise movements during gripping and movement. The movable bracket 22 is movably connected to the top frame 21, driving the clamping arm 23 and positioning jaw 24 to move and rotate. Through the flexible movement of the movable bracket 22, the position adjustment and centering operation of the sand box and lid are realized, ensuring the smooth progress of the box closing process. The clamping arm 23 provides support and motion guidance for the positioning jaw 24, enabling it to accurately grip and release the sand box and lid, and complete various complex actions such as movement and rotation under the drive of the movable bracket 22. The positioning jaw 24 directly contacts the sand box and lid, and through cooperation with the positioning clamping hole, achieves precise gripping and positioning of the sand box and lid, ensuring accurate positioning during conveying and box closing.

[0035] When using the above-mentioned mold fitting and box assembly device, the following steps are included: the sand box and the box cover are respectively transported to the first receiving bracket 11 and the second receiving bracket 12. The movable bracket 22 of the clamping mechanism 20 drives the clamping arm 23 to move above the sand box, and the positioning claw 24 is aligned with the positioning clamping hole on one end face of the sand box; the positioning claw 24 is inserted into the positioning clamping hole and clamped to determine the position and center of the sand box; the movable bracket 22 then drives the clamping arm 23 to move above the box cover, and the positioning claw 24 is aligned with the positioning clamping hole on one end face of the box cover and clamps the box cover, and moves the box cover to the top of the sand box according to the determined position and center of the sand box; during the movement, the movable bracket 22 drives the clamping arm 23 and the box cover to perform a 360° rotation operation, so that the box cover and the sand box are set opposite each other and ensure the centering state, so that the two can be accurately aligned when the box is closed; after the centering is completed, the movable bracket 22 slowly descends, so that the box cover and the sand box complete the box closing operation. The positioning gripper 24 maintains a clamping state on the box cover during the box closing process to ensure the stability and accuracy of the box closing; after the box closing is completed, the positioning gripper 24 is released, completing the entire process of mold matching and box closing; the movable bracket 22 and the clamping arm 23 are reset under the support of the top frame 21, ready for the next round of mold matching and box closing operation.

[0036] Based on the above embodiments, the movable support 22 includes a first frame 221, a second frame 222, a first drive member 223, and a second drive member 224. The first frame 221 and the second frame 222 are arranged parallel to each other. The first drive member 223 is fixedly mounted on the top frame 21 and connected to the first frame 221, and is used to drive the first frame 221 to reciprocate between the first support bracket 11 and the second support bracket 12. The second drive member 224 connects the first frame 221 and the second frame 222, and is used to drive the second frame 222 to reciprocate along a vertical plane. The first frame 221 and the second frame 222 are arranged parallel to each other to form a stable frame structure, providing good support for the clamping arm 23 and the positioning gripper 24. The support and motion guidance ensure the stability and accuracy of the clamping arm 23 and positioning gripper 24 during movement. The first drive component 223 and the second drive component 224 provide a precise power source for the horizontal and vertical movement of the movable bracket 22, enabling accurate gripping, conveying and alignment of the sand box and box cover, ensuring the automation and precision of the entire mold assembly and box closing process. Through the precise driving of the first drive component 223 and the second drive component 224, and the stable support of the first frame 221 and the second frame 222, the position and movement trajectory of the sand box and box cover can be controlled more accurately, effectively reducing alignment errors, improving the accuracy and reliability of mold assembly and box closing, and thus improving product quality and mold service life.

[0037] Based on the above embodiment, the second frame 222 is recessed on the side facing the receiving mechanism 10 to form an assembly groove 222a. The ends of the two clamping arms 23 are located at both ends of the assembly groove 222a and move along the length of the assembly groove 222a. The assembly groove 222a provides precise installation and movement space for the ends of the clamping arms 23. By precisely guiding and restricting the ends of the clamping arms 23 through the assembly groove 222a, it is ensured that the clamping arms 23 always maintain linear movement during movement, which can effectively reduce the swaying of the clamping arms 23 during movement. The movement and offset of the clamping arm 23 improve the gripping and positioning accuracy of the sand box and box cover, thereby further improving the accuracy of mold assembly and box fitting, reducing the alignment error caused by the offset of the clamping arm 23, and improving the assembly quality and production efficiency of the mold. In addition, the concave design of the assembly groove 222a makes the structure of the entire movable support 22 more compact and reduces unnecessary space occupation. At the same time, the movement of the end of the clamping arm 23 within the assembly groove 222a also increases the connection stability between the clamping arm 23 and the movable support 22, improving the reliability and safety of the equipment during operation.

[0038] Based on the above embodiment, a clamping drive assembly is provided in the assembly slot 222a. The clamping drive assembly includes a third drive member 251, a transmission chain 252, and a transmission gear 253. A linkage block 231 is fixedly provided at the end of each clamping arm 23. The third drive member 251 is arranged along the moving direction of the clamping arm 23, and its two ends are fixedly connected to two linkage blocks 231 respectively. Two transmission gears 253 are provided, located at both ends of the length direction of the two assembly slots 222a respectively. The transmission chain 252 wraps around the two transmission gears. On the outer side of wheel 253, both linkage blocks 231 are connected to the inner side of transmission chain 252; the third drive component 251 provides power, which, through the transmission chain 252 and transmission gear 253, causes the linkage block 231 at the end of clamping arm 23 to drive clamping arm 23 to move stably and synchronously along the length direction of assembly groove 222a, ensuring that the positioning claw 24 is accurately aligned with the positioning clamping holes of sand box and box cover and forms a clamping effect, ensuring the consistency and coordination of clamping arm 23 during movement, and improving the gripping and positioning accuracy of sand box and box cover.

[0039] Based on the above embodiment, the transmission chain 252 is further provided with a stop member 254. Two stop members 254 are provided, located at the joints of the transmission chain 252 respectively. Each stop member 254 is connected to the side of the two linkage blocks 231 opposite to the third drive member 251. The stop member 254 can effectively limit the extension range of the transmission chain 252 during transmission. This helps to prevent the transmission chain 252 from becoming loose or falling off due to overextension, ensuring that the transmission chain 252 is always in a taut state, thereby improving the transmission efficiency and stability of the clamping drive assembly, and enabling the clamping arm 23 to reach the predetermined position more accurately during movement. When the clamping arm 23 moves to the limit position, the stop member 254 can promptly prevent the transmission chain 252 from extending further, preventing the clamping arm 23 from exceeding the effective working range, thereby improving the alignment accuracy of the positioning jaws 24 with the positioning clamping holes of the sand box and the box cover.

[0040] Based on the above embodiments, each positioning gripper 24 includes a mounting plate 241 and two positioning feet 242. The mounting plate 241 is horizontally positioned, and its middle part is rotatably connected to the side opposite to the end of the gripping arm 23. The mounting plate 241 protrudes at both ends of its side facing the sand box or box cover, forming an assembly surface for the two positioning feet 242 to connect. The assembly surface provides a stable mounting base for the positioning feet 242, ensuring that the positioning feet 242 can be evenly stressed during the gripping process, reducing gripping failure or damage to the sand box or box cover caused by uneven stress. The shape and size of the positioning feet 242 match the positioning clamping holes on the sand box or box cover, and can be precisely inserted into the clamping holes to achieve fast and accurate gripping and positioning of the sand box and box cover. At the same time, the rotatable connection between the mounting plate 241 and the end of the gripping arm 23 can be finely adjusted according to the actual position of the sand box and box cover during the gripping process, further improving the positioning accuracy and reliability.

[0041] Based on the above embodiments, the clamping arm 23 is equipped with a positioning drive assembly at one end where the positioning gripper 24 is mounted. The positioning drive assembly includes an active rod 261 and an auxiliary rod 262. One end of the auxiliary rod 262 passes through the end of the clamping arm 23 and is fixedly connected to the side of the mounting plate 241 opposite to the positioning foot 242. The other end is connected to the active rod 261 for transmission. The axes of the active rod 261 and the auxiliary rod 262 are perpendicular to each other. The positioning drive assembly enables the positioning gripper 24 to be precisely angled, converting the linear motion of the active rod 261 into the rotational motion of the auxiliary rod 262, thereby driving the mounting plate 241 and the positioning gripper 24 to adjust their angles. This ensures that the positioning gripper 24 can be accurately aligned with the positioning clamping holes on the sand box and the box cover, and enables the box cover to flip.

[0042] Based on the above embodiments, both the first receiving bracket 11 and the second receiving bracket 12 include a guide frame 111, a stop frame 112, and several guide rollers 113; the guide frame 111 is fixedly installed on the ground, and several guide rollers 113 are arranged sequentially along the length of the guide frame 111; the stop frame 112 is movably connected to the guide frame 111 and includes multiple support plates 112a, which are spaced apart between the guide rollers 113 and reciprocate along a vertical plane; when the sand box or box cover moves to the set position... When in use, the movement of the support plate 112a allows the stop frame 112 to flexibly stop and position the sand box and the box cover as needed, ensuring that the position of the sand box and the box cover is accurate during the gripping and box closing process. Through the precise guidance of the guide frame 111 and the guide roller 113, and the flexible stopping of the stop frame 112, the high precision of the sand box and the box cover during the conveying and positioning process can be ensured, reducing alignment errors, improving the overall quality of mold matching and box closing, and reducing product defects and mold damage caused by inaccurate conveying.
