Description

Technical Field

[0001] This utility model relates to the field of mold assembly machines, and in particular to a rotary mold assembly machine. Background Technology

[0002] Current mainstream mold-closing assembly machines generally adopt a single-station design, mainly composed of core components such as a frame, drive unit, guide pillars, guide sleeves, upper mold, and lower mold. To ensure assembly accuracy during the mold-closing process, these machines require targeted design during manufacturing: the frame is usually machined from castings to enhance structural stability; the guide pillars and guide sleeves need to be of larger specifications to further improve guiding accuracy and load-bearing capacity. Therefore, traditional mold-closing assembly machines are typical high-precision equipment, not only with high manufacturing costs, but also with applications largely limited to the production of products requiring stringent assembly accuracy.

[0003] Meanwhile, the mold-closing and assembly of large workpieces also presents unique technological challenges: due to their large weight and high inertia, conventional automated feeding equipment such as vibratory feeders is difficult to adapt, forcing the mold-closing and assembly machine to use manual feeding. However, the operational precision of manual feeding is far lower than that of mechanical feeding, inevitably introducing greater workpiece position errors and affecting the accuracy of subsequent mold-closing processes.

[0004] For products that only need to meet general assembly tolerances, there are obvious compatibility issues with using traditional high-precision mold-closing assembly machines: on the one hand, the high investment cost of the equipment does not match the actual precision requirements of the product, resulting in unnecessary cost waste; on the other hand, the single-station operation mode itself has low production efficiency, and even if efficiency is improved by combining it with automated equipment, a large number of auxiliary equipment are required, which leads to a significant increase in the overall equipment footprint and places higher demands on the production site space.

[0005] In summary, how to reduce the error of manual material loading, improve accuracy, and increase production efficiency at the same time, given the significant positional error inherent in manual material loading, has become a key issue that urgently needs to be addressed in the current mold assembly machine field. Utility Model Content

[0006] In view of this, the present invention aims to propose a rotary mold assembly machine to reduce manual feeding errors, improve accuracy, and increase production efficiency.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] A rotary mold assembly machine includes an upper mold and a lower mold, and further includes a four-station turntable and a mold closing lifting column. The four-station turntable is equipped with a divider and four station brackets, and each station bracket is equipped with a lower mold.

[0009] The mold closing lifting column is located above one of the four-station turntables and is used to install and drive the upper mold to perform lifting and lowering movements.

[0010] The upper mold includes a guide post, a floating mechanism, and an upper die, wherein the guide post and the floating mechanism are mounted on the upper die, and the lower mold includes a lower die and a guide pin mounted on the lower die;

[0011] The floating mechanism can float in the X and Y directions to compensate for positional errors during mold closing.

[0012] The floating mechanism includes a first linear bearing, a second linear bearing, and a guide shaft, with the first and second linear bearings mounted on the guide shaft.

[0013] Furthermore, the four-station turntable also includes a base, four station detection devices, support columns, station dividing guardrails, a central frame, a barcode scanning column, support pads, and a first pad.

[0014] The base is fixed to the ground, and the divider and four station detection devices are installed on the base. The station detection devices are used to detect the station position and control the rotation and positioning of the divider.

[0015] The central frame is fixed on the divider, and the central frame is surrounded by station dividing guardrails and station brackets.

[0016] Each workstation bracket is fitted with a first pad and a support pad, and each support pad is fitted with a support column. The barcode scanning column is fixed to the ground and located next to one of the workstations.

[0017] Furthermore, the support column includes a support column, a second gasket, a bearing housing, a bearing, and a shaft;

[0018] The support column is fixed to the ground, and the second gasket and the bearing seat are mounted on the support column;

[0019] The bearing is mounted in the bearing housing via the shaft, and is used to support the workstation bracket and allow it to rotate.

[0020] Furthermore, the mold-closing lifting column is a pneumatic, hydraulic, or electric drive device.

[0021] Furthermore, the four-station turntable is driven to rotate by the divider, thereby enabling sequential switching between the stations.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] The rotary mold-closing assembly machine of this utility model is equipped with a four-station rotary table and a divider to realize the sequential switching and parallel operation of each station, so as to carry out different processes such as scanning, pre-processing and mold closing at the same time, which greatly shortens the production cycle of a single product and significantly improves the overall production efficiency. By setting a floating mechanism in the upper mold that can float along the X and Y directions, the position error of the station can be automatically compensated during the mold closing process. It does not need to rely on the traditional high-precision casting frame and robust guide pillars and guide sleeves, reducing the equipment manufacturing cost, while adapting to the production needs of products with general assembly tolerances.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] This embodiment relates to a rotary mold-closing assembly machine, which has low manufacturing costs and is suitable for products with general assembly tolerances. This rotary mold-closing assembly machine reduces manual feeding errors, improves accuracy, increases production efficiency, and reduces operator workload.

[0042] Based on the above design concept, an exemplary structure of the rotary mold-closing assembly machine in this embodiment is as follows: Figures 1-11As shown, it mainly includes an upper mold 003 and a mold closing lifting column 004, and also includes a four-station turntable 001 and a mold closing lifting column 004. The four-station turntable 001 is equipped with a divider 001-2 and four station brackets 001-7, each station bracket 001-7 housing a lower mold 002. A detection card 001-11 is installed at different positions of the four station fixtures on the four-station turntable 001. The mold closing lifting column 004 is positioned above one of the stations of the four-station turntable 001 and is used to install and drive the upper mold 003. The upper mold 003 includes guide pillars 003-1, a floating mechanism 003-2, and an upper die 003-3. Guide pillars 003-1 and the floating mechanism 003-2 are mounted on the upper die 003-3. The lower die 002 includes a lower die 002-2 and a guide pin 002-1 mounted on the lower die 002-2. The floating mechanism 003-2 can float in the X and Y directions to compensate for positional errors during mold closing. The four-station turntable 001 is driven to rotate by a divider 001-2, enabling sequential switching between stations. It should be noted that the X and Y directions are as follows... Figure 2 As shown, the splitter 001-2 in this embodiment is a WEISS splitter with model number ACR0560S_RXF57DR2L100L4.

[0043] The four-station turntable 001 also includes a base 001-1, four station detection devices 001-3, a support column 001-4, station dividing guardrails 001-5, a central frame 001-6, a barcode scanning column 001-8, a support pad 001-9, and a first pad 001-10; the base 001-1 is fixed to the ground, the divider 001-2 and the four station detection devices 001-3 are installed on the base 001-1, and the station detection devices 001-3 are used to detect the station positions. The rotation and positioning of the divider 001-2 are controlled; the central frame 001-6 is fixed on the divider 001-2, and the station dividing guardrail 001-5 and station bracket 001-7 are fixed around the central frame 001-6; a first pad 001-10 and a support pad 001-9 are installed under each station bracket 001-7, and a support column 001-4 is installed under each support pad 001-9; the scanning column 001-8 is fixed to the ground and located next to one of the stations.

[0044] As the turntable rotates, different sensor signals are triggered when the detection cards 001-11 at different workstations pass through the fixed workstation detection device 001-3 (such as a set of sensors). The control system can uniquely determine which workstation it is currently at based on the signal received from a specific sensor, thereby controlling the divider 001-2 to stop rotating and achieving precise workstation positioning.

[0045] The support column 001-4 includes a support column 001-4.1, a second gasket 001-4.2, a bearing housing 001-4.3, a bearing 001-4.4, and a shaft 001-4.5. The support column 001-4.1 is fixed to the ground, and the second gasket 001-4.2 and the bearing housing 001-4.3 are installed on the support column 001-4.1. The bearing 001-4.4 is installed in the bearing housing 001-4.3 via the shaft 001-4.5, and is used to support the workstation bracket 001-7 and allow it to rotate.

[0046] The mold closing lifting column 004 is a pneumatic, hydraulic or electric drive device.

[0047] like Figure 1 and Figure 2 As shown, four lower molds 002 are fixed on the four-station turntable 001. An upper mold 003 is located above one of the stations on the four-station turntable 001. The upper mold 003 is installed on the mold closing lifting column 004.

[0048] like Figures 3-5 As shown, the base 001-1 is fixed to the ground, with a divider 001-2 and four station detection devices 001-3 fixed on top. The station detection devices 001-3 detect the station positions using sensors. A central frame 001-6 is fixed to the divider 001-2, and station dividing guardrails 001-5 and station brackets 001-7 are fixed around the central frame 001-6. Each station bracket 001-7 has a first pad 001-10 and a support pad 001-9 underneath. Each support pad 001-9 has a support column 001-4 underneath. A barcode scanning column 001-8 is located near one of the stations and fixed to the ground.

[0049] like Figure 6 As shown, support column 001-4.1 is fixed to the ground, and a second shim 001-4.2 and bearing housing 001-4.3 are mounted on top of it. Bearing 001-4.4 is fixed to bearing housing 001-4.3 by shaft 001-4.5.

[0050] like Figure 7 As shown, the lower mold 002-2 is fixed on the station bracket 001-7, and the lower mold 002 is fixed on the station bracket 001-7 by two guide pins 002-1.

[0051] like Figure 8 As shown, the upper mold 003-3 is fixed on the mold closing lifting column 004, and two guide columns 003-1 and a floating mechanism 003-2 are fixed on the upper mold 003-3.

[0052] like Figure 9 and Figure 10As shown, the floating mechanism 003-2 includes a first linear bearing 003-2.1, a second linear bearing 003-2.2, and a guide shaft 003-2.3. The first linear bearing 003-2.1 and the second linear bearing 003-2.2 are mounted on the guide shaft 003-2.3. When the guide post 003-1 approaches the guide pin 002-1, if there is a positional error, the lateral force on the guide post will push 003-2.1, the first linear bearing, and / or 003-2.2 and the second linear bearing, causing them to produce a small sliding displacement along 003-2.3 and the guide shaft, thereby achieving "floating" in both the X and Y directions to compensate for the positional error and ensure smooth and precise mold closing.

[0053] When using the rotary mold-closing assembly machine described in this embodiment, such as Figure 11 As shown, the four-station turntable 001 rotates clockwise. At station one, the lower mold product is placed on the lower mold 002, and the barcode scanner on the barcode scanning column 001-8 next to the station scans the product. After scanning, the turntable rotates 90 degrees via the divider 001-2 to enter station two for operation (station two can be for placing the upper mold product or for other processes). After station two is completed, the divider 001-2 rotates 90 degrees to enter station three for operation (station three can be for placing the upper mold product or for other processes). After station three is completed, the divider 001-2 rotates 90 degrees to enter station four for operation. Station four is equipped with a mold closing lifting column 004, which drives the upper mold 003 to move downward. When the guide column 003-1 approaches the guide pin 002-1, the floating mechanism 003-2 enters a floating state. The floating mechanism 003-2 can float in the X and Y directions. The mold closing lifting column 004 drives the upper mold 003 to continue moving downwards, guided by the guide column 003-1 and guide pin 002-1 until it reaches the required position. The upper mold 003 then holds the upper mold product, completing the positioning of the upper mold product before proceeding with the mold closing and assembly operation. After the assembly operation is completed, the upper mold 003 releases the product, and the mold closing lifting column 004 drives the upper mold 003 back to its original position. The guide column 003-1 and guide pin 002-1 engage at their initial position, the floating mechanism 003-2 stops floating, and the mold closing lifting column 004 drives the upper mold 003 back to its final position. The divider 001-2 rotates 90 degrees and enters station one, completing the product off-line cycle.

[0054] As described above, the floating mechanism 003-2 on the rotary mold-closing assembly machine can compensate for errors in the X and Y directions at each station. The bearings 001-4.4 on the support columns 001-4 cooperate with the support pads 001-9 at each station to position the mold height. The rotary mold-closing assembly machine can have multiple rotary table stations, which can be set according to the product process. External equipment can be added to each rotary table station as needed.

[0055] The rotary mold-closing assembly machine using the above-described implementation scheme effectively addresses the pain points of traditional single-station mold-closing assembly machines. Centered on a four-station rotary table 001, and driven by a divider 001-2 and precisely positioned by a station detection device 001-3, it enables sequential switching and parallel operation of each station, significantly improving production efficiency. Furthermore, it requires only manual replenishment of raw materials and finished products, significantly reducing operator workload. Through the floating mechanism 003-2 of the upper mold 003, error compensation in the X and Y directions replaces the high-precision reliance of traditional equipment on casting frames, robust guide pillars, and guide sleeves. This allows it to adapt to products with general assembly tolerances without incurring high manufacturing costs, lowering the equipment investment threshold and reducing errors caused by manual material handling. The number of rotary table stations can be flexibly set according to product processes, and each station can be equipped with external devices as needed to meet diverse production requirements.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
