Description

Technical Field

[0001] The utility model relates to the field of plastic product production, and more specifically, to an injection mold for plastic manufacturing with a switching structure. Background Art

[0002] Injection molds are important tools for plastic product production. They inject molten plastic into the mold, and then the plastic cools and solidifies in the mold to finally form the required plastic products. Under certain conditions such as a certain temperature and pressure, materials can be molded into a certain shape and maintain the shape unchanged at normal temperature. Plastics have good plasticity, so the production of plastic products is extremely extensive.

[0003] However, most current injection molds for plastic manufacturing have the following problems:

[0004] First, for existing injection molds for plastic manufacturing, when using the mold for plastic manufacturing, most of the injection molds used are installed and used by multiple bolts or welding. When using the injection mold for a long time, the injection mold is prone to damage and other situations. When performing maintenance or switching, it is time-consuming and laborious to disassemble the injection mold, which affects the production efficiency and is inconvenient for maintaining and switching the used injection mold.

[0005] Second, for existing injection molds for plastic manufacturing, when performing plastic manufacturing, after the plastic part is taken out after production, the next plastic part can be produced. The production efficiency is relatively low, and there are some small impurities and dust remaining in the mold after production. If not cleaned and collected, it is easy for the dust to affect the production of the next object, and it is inconvenient for convenient cleaning.

[0006] Therefore, we make improvements and propose an injection mold for plastic manufacturing with a switching structure. Summary of the Utility Model

[0040] As Figure 2 shown, as a preferred implementation manner, on the basis of the above manner, further, a rotating motor 26 is fixedly connected to the second hydraulic cylinder 25, a collecting box 27 is fixedly connected to the rotating motor 26, a cover plate 28 is bolted to the collecting box 27, and the bottom end surface of the moving block 11 is attached to the inner bottom end surface of the mounting plate 6, which can ensure that when the moving block 11 moves, it can move smoothly through the support of the inner bottom end surface of the mounting plate 6.

[0041] As Figure 5 shown, as a preferred implementation manner, on the basis of the above manner, further, a pump body 29 is installed on the connecting plate 21, a delivery hose 30 is installed on the pump body 29, the other end of the delivery hose 30 is installed on the collecting box 27, springs 15 are symmetrically distributed on the left and right sides inside the fixing plate 14, and the springs 15 are in one-to-one correspondence with the clamping blocks 17 through the guiding blocks 16, which can ensure that the cooperation of the two clamping blocks 17 can clamp and limit the lower injection mold 13 from left and right.

[0042] As Figure 6 shown, as a preferred implementation manner, on the basis of the above manner, further, a protective net 31 is fixedly connected to the collecting box 27, a suction pipe 32 is fixedly connected to the collecting box 27, a cleaning brush 33 is fixedly connected to the collecting box 27, and the suction pipes 32 are equidistantly installed on the collecting box 27, which can ensure that the plurality of suction pipes 32 can uniformly suck and collect the swept dust.

[0043] Specifically, when the injection mold for plastic manufacturing with a switching structure is in use: Combining Figures 1-7When replacing and installing the lower injection mold 13, the lower injection mold 13 is placed on the mounting plate 6, and when the second servo motor 7 is turned on to drive the third bevel gear 8 to rotate, the third bevel gear 8 can drive the threaded rod 10 to operate through the fourth bevel gear 9, and when the threaded rod 10 rotates, the moving block 11 can be pushed to move by the thread, and when the moving block 11 moves outward, the lower injection mold 13 can be pushed to move at the same time through the clamping plate 12, and after the lower injection mold 13 is attached to the push plate 18, the clamping plate 12 continues to push the lower injection mold 13 to move, and when the lower injection mold 13 pushes the push plate 18 to move, the push plate 18 can be supported by the guide rod 19 to move smoothly, and the groove on the push plate 18 can push the clamping block 17 to move, and the clamping block 17 can move when moving. The guide block 16 can move smoothly under the guidance of the guide block 16, and the guide block 16 can squeeze the spring 15 when moving. The clamping blocks 17 on both sides can clamp the lower injection mold 13 to the left and right when moving, thereby improving the stability of the installation and fixation of the lower injection mold 13 and avoiding shaking and deviation during use. The lower injection mold 13 is installed and fixed. When the lower injection mold 13 needs to be replaced, the threaded rod 10 can be driven to rotate in the opposite direction. The threaded rod 10 drives the moving block 11 and the clamping plate 12 to move inward and detach from one side of the lower injection mold 13. After the lower injection mold 13 is unobstructed, the guide block 16 and the clamping block 17 are driven to reset under the push of the spring 15.

[0044] In order to improve production efficiency, raw materials can be added to the lower injection mold 13. When the first servo motor 2 in the device housing 1 is started to drive the first bevel gear 3 to rotate, the first bevel gear 3 can drive the connecting frame 5 to rotate through the second bevel gear 4. At the same time, when the connecting frame 5 drives the mounting plate 6 to move, the lower injection mold 13 on the mounting plate 6 moves below the upper injection mold 24. After the infrared signal emitter 20 and the infrared signal receiver 22 on the fixing plate 14 are in the same vertical line to receive the signal, the rotation of the mounting plate 6 stops, playing a role in it. Then, the first hydraulic cylinder 23 on the connecting plate 21 is started to drive the upper injection mold 24 to move down, facilitating the forming and pressing of the material in the lower injection mold 13. After production is completed, the mounting plate 6 is controlled to continue rotating, and the upper injection mold 24 presses and forms the lower injection mold 13 on the lower side. The material in the lower injection mold 13 that has separated from below the upper injection mold 24 can be taken out. Then, the mounting plate 6 continues to rotate and moves below the collection box 27. The second hydraulic cylinder 25 can be controlled to push the collection box 27 down, inserting the collection box 27 and the cleaning brush 33 into the lower injection mold 13. When the rotating motor 26 is running, the cleaning brush 33 on the collection box 27 can rotate to clean the impurities in the lower injection mold 13. When the pump body 29 is started, the dust swept off can be sucked and collected through the multiple suction pipes 32 on the collection box 27, avoiding affecting the production quality. The protective net 31 installed on the collection box 27 prevents dust from falling into the pump body 29 from the conveying hose 30, protecting the pump body 29. When it is necessary to take out and clean the dust in the collection box 27, the cover plate 28 on the collection box 27 can be detached to clean the internal dust.

[0045] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the utility model are covered by the scope of the claims of the present invention.
