Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a multi-station portable mold with interchangeable molds. Background Technology

[0002] Injection molds are key tools used in the production of plastic products and occupy a central position in the plastics processing industry. Through the injection molding process, thermoplastic or thermosetting plastics are injected into the mold cavity under high temperature and pressure, and after cooling and solidification, plastic products of the desired shape and size are obtained.

[0003] The multi-station injection mold disclosed in the authorization announcement number CN209320194U is a multi-station injection mold that uses fastening bolts to adjust the clamping plate to fix the injection mold. At the same time, the height of the support plate can be adjusted by adjusting the bolts to facilitate the casting of the injection mold. Three clamping plates are provided on the inner side of the fixing plate, which can fix the injection mold in multiple ways, realize multi-station injection, and improve work efficiency.

[0004] While multi-station injection molds improve work efficiency, they also introduce certain operational limitations. Because the injection molds are fixed in place simultaneously, it's impossible to promptly unload and replace individual molds after injection molding. This can result in finished injection molded products having to wait for other molds to complete their injection process before unloading, increasing waiting time and production costs.

[0005] Therefore, it is necessary to invent a multi-station, portable injection mold with mold changing capability to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-station, portable, mold-changing injection mold to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-station portable mold for mold changing, comprising a worktable, a loading tray rotatably connected to the top center of the worktable, a loading area set at each of the four corners of the loading tray, an injection mold placed on the top of each loading area, a fixed bracket fixedly connected to one side of the top of the worktable, an injection molding machine installed in the middle of the fixed bracket, one of the injection molds being located directly below the output end of the injection molding machine, a motor chamber opened inside the worktable, a No. 1 motor installed inside the motor chamber, the output shaft of the No. 1 motor extending to the top of the worktable and connected to the loading tray for transmission, a controller installed on the surface of the injection molding machine, and both the injection molding machine and the No. 1 motor being electrically connected to the controller.

[0008] By setting a rotating loading tray on the top of the workbench and setting loading areas at the four corners of the loading tray, multiple injection molds can be accommodated at the same time, which facilitates multi-station injection molding and helps to improve production efficiency.

[0009] Preferably, each of the loading areas is provided with a set of clamping mechanisms at its top, and the injection mold is clamped and fixed by the clamping mechanisms. The number of clamping mechanisms in each set is set to four, and the four clamping mechanisms are evenly distributed around the outside of the injection mold.

[0010] The injection mold is clamped and fixed by a clamping mechanism. Each set of clamping mechanisms consists of four clamping mechanisms, which are evenly distributed around the outside of the injection mold to provide uniform clamping force. This ensures the stability of the mold during the injection process and avoids production accidents caused by mold displacement or detachment.

[0011] Preferably, the clamping mechanism consists of a base plate, a second motor, a main shaft, a clamping block, and an end block. The second motor and the end block are respectively installed at the top two ends of the base plate. One end of the main shaft is connected to the output shaft of the second motor, and the other end of the main shaft is rotatably connected to the end block. One end of the clamping block is fixedly sleeved on the surface of the main shaft, and the other end of the clamping block is fixedly connected to a rubber pad.

[0012] The main shaft is driven to rotate by the No. 2 motor, which in turn causes the clamping block to flip, thus achieving clamping or releasing actions. This automates the mold clamping process and improves production efficiency. A rubber pad is fixed to one end of the clamping block, which increases the flexibility and friction of the clamping, preventing the mold from being scratched during clamping and improving the stability of the mold.

[0013] Preferably, each of the loading areas is equipped with a control switch, and the second motor of each clamping mechanism is electrically connected to the corresponding control switch.

[0014] Each loading zone has an independent control switch, which can individually control the clamping and releasing of the corresponding clamping mechanism, improving the flexibility and convenience of operation.

[0015] Preferably, an operating door is hinged to the front of the workbench, the operating door is located at the opening of the motor compartment, and the surface of the operating door is provided with heat dissipation holes.

[0016] The control door facilitates the maintenance and repair of the No. 1 motor in the motor room, improving the maintainability of the equipment. The heat dissipation holes on the surface of the control door improve the heat dissipation efficiency of the motor room, ensuring the stability and lifespan of the No. 1 motor under long-term operation.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] 1. Multiple injection molds can be simultaneously loaded through multiple loading areas on the loading tray, enabling multi-station injection molding. The loading tray is then rotated by a No. 1 motor to move the completed injection molds to other positions for unloading. At the same time, the injection molds to be injected are rotated to the output end of the injection molding machine for the next round of injection molding. This allows for continuous injection and unloading of multiple injection molds, greatly improving production efficiency.

[0019] 2. Each loading area is equipped with an independent control switch to control the clamping and releasing of the corresponding clamping mechanism, which allows operators to easily operate each mold individually, greatly enhancing the flexibility and convenience of operation.

[0027] This utility model provides, for example Figure 1-4The multi-station portable mold changer shown includes a workbench 1, a loading tray 2 rotatably connected to the top center of the workbench 1, a loading area set at each of the four corners of the loading tray 2, and an injection mold 3 placed on the top of each loading area. A fixed bracket 4 is fixedly connected to one side of the top of the workbench 1, and an injection molding machine 5 is installed in the middle of the fixed bracket 4. One of the injection molds 3 is located directly below the output end of the injection molding machine 5. A motor chamber 6 is opened inside the workbench 1, and a first motor 7 is installed inside the motor chamber 6. The output shaft of the first motor 7 extends to the top of the workbench 1 and is connected to the loading tray 2 for transmission. A controller 8 is installed on the surface of the injection molding machine 5, and both the injection molding machine 5 and the first motor 7 are electrically connected to the controller 8.

[0028] In one aspect of this embodiment, each loading area is provided with a set of clamping mechanisms 9 at its top. The injection mold 3 is clamped and fixed by the clamping mechanisms 9. Each set of clamping mechanisms 9 consists of four clamping mechanisms 9, which are evenly distributed around the outside of the injection mold 3. Each clamping mechanism 9 is composed of a base plate 10, a second motor 11, a main shaft 12, a clamping block 13, and an end block 14. The second motor 11 and the end block 14 are respectively installed at the top two ends of the base plate 10. One end of the main shaft 12 is connected to the second motor 11. The output shaft is driven and connected. The other end of the main shaft 12 is rotatably connected to the end block 14. One end of the clamping block 13 is fixedly sleeved on the surface of the main shaft 12, and the other end of the clamping block 13 is fixedly connected to a rubber pad 15. Each loading area surface is equipped with a control switch 16. The second motor 11 of each clamping mechanism 9 is electrically connected to the corresponding control switch 16. The front of the workbench 1 is hinged with an operating door 17. The operating door 17 is located at the opening of the motor chamber 6.

[0029] The injection molding machine 5, motor 7, controller 8, motor 11 and control switch 16 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figure 1-4 When using this utility model, firstly, four injection molds 3 are placed one by one on the four loading areas of the loading tray 2. Each injection mold 3 is clamped and fixed by a corresponding clamping mechanism 9. The clamping mechanism 9 consists of a base plate 10, a second motor 11, a main shaft 12, a clamping block 13, and an end block 14. The second motor 11 is started by the control switch 16 on the surface of each loading area. The output shaft of the second motor 11 drives the main shaft 12 to rotate, which in turn drives the clamping block 13 to flip until the rubber pad 15 at one end of the clamping block 13 abuts against the outside of the injection mold 3, thereby achieving the clamping and holding of the injection mold 3.

[0032] When injection molding is required, the injection molding machine 5 is started by the controller 8, and the first motor 7 is controlled to work. The output shaft of the first motor 7 drives the loading plate 2 to rotate, and rotates the injection mold 3 to be injected to be directly below the output end of the injection molding machine 5. The injection molding machine 5 injects the molten plastic into the cavity of the injection mold 3. After cooling and solidification, the desired plastic product is obtained.

[0033] After injection molding is completed, motor 7 starts again, rotating the injection mold 3 that has been injected to another position for unloading. At the same time, the injection mold 3 to be injected is rotated to the output end of the injection molding machine 5 for the next round of injection molding. This allows for continuous injection and unloading of multiple injection molds 3, greatly improving production efficiency.
