Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, in particular to an injection molding machine mold ejection and flipping component. Background Art

[0002] As a special manufacturing equipment for plastic products, the rubber injection machine injects thermoplastics or thermosetting plastics into different molding molds to plasticize and obtain products that are consistent with the shape of the mold cavity. In addition, different products correspond to different molding molds. Therefore, the molding molds in the injection machine need to be replaced frequently and cleaned during or after use.

[0003] At present, the structure used for installing the molding mold in the existing rubber injection machines on the market is a clamping mechanism, which can realize the installation, clamping and opening of the static mold and the dynamic mold of the molding mold. At this time, the clamping mechanism includes a relatively static base and a relatively dynamic mobile structure, the static mold is installed on the base, and the dynamic mold is installed on the mobile structure. However, for the injection machine, in the vertical clamping mechanism, the dynamic mold can move in the vertical direction relative to the static mold, so as to meet the clamping requirements. However, in the actual processing process, the molding mold is usually fixed to the corresponding structure by the die assembly. When the product needs to be taken out, replaced or cleaned later, it is usually necessary to first release the restriction of the die assembly on the molding mold, and then manually drag out the molding mold. Although the above method can meet the operation requirements, since the molding mold is usually heavy, it is not only time-consuming and laborious to manually drag out the mold, but also requires the hand to reach into the clamping mechanism for operation, which has a great safety hazard and still needs to be improved.

[0026] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the following embodiments are combined with the attached Figure 1 to the attached Figure 5 to specifically elaborate on the technical solutions provided by the present utility model, but the following content shall not be construed as a limitation to the present utility model.

[0027] Figure 1 It is a structural diagram of an embodiment of an ejection and tipping assembly of an injection mold of the present utility model. As Figure 1 shown, the ejection and tipping assembly of the injection mold provided in this embodiment includes: a frame 1, a jacking mechanism 2 and a tipping mechanism 3. Moreover, the jacking mechanism 2 is installed on the frame 1, and the tipping mechanism 3 is installed on the jacking mechanism 2. The mold can be jacked to a predetermined height through the jacking mechanism 2, so that the mold can be separated from the original structure and provide enough space for the subsequent tipping of the mold. Then, the tipping mechanism 3 drives the mold to tip by a predetermined angle, so that the mold can be tipped to a predetermined area, which is convenient for the operator to take out the product, replace the mold and clean the mold, saving time and effort in operation. In addition, the structure is simple and the operation is convenient. In addition, after the mold is tipped out, it can effectively avoid the potential safety hazard problem that the hand needs to reach into the mold clamping mechanism during the existing manual operation, improving the operation safety.

[0028] Figure 2 It is a structural diagram of the jacking mechanism of a preferred embodiment of the present utility model. As Figure 1 and Figure 2As shown in the figure, the lifting mechanism 2 further includes a platform 21, a lifting drive 22, and a moving seat 23. During installation, the lifting drive 22 is installed on the frame 1 in the vertical direction, achieving stable installation of the lifting drive 22. At the same time, the drive shaft of the lifting drive 22 is arranged vertically upward, ensuring that the lifting drive 22 can provide power for the subsequent lifting of the platform 21. In addition, the platform 21 is installed on the drive shaft of the lifting drive 22, enabling the platform 21 to perform height adjustment in the vertical direction under the action of the lifting drive 22. At the same time, the moving seat 23 is installed on the platform 21, allowing the moving seat 23 to move up and down with the platform 21, providing conditions for the subsequent flipping mechanism 3 to move with the lifting mechanism 2 to adapt to the state changes of the lifting mechanism 2.

[0029] Figure 3 It is a structural diagram of the flipping mechanism of a preferred embodiment of the present utility model. As Figure 1 and Figure 3 shown in the figure, the flipping mechanism 3 further includes a telescopic drive 31, a flipping frame 32, and a pull rod 33. During installation, the telescopic drive 31 is installed on the moving seat 23 and the telescopic shaft of the telescopic drive 31 is arranged vertically downward, not only achieving the purpose of the telescopic drive 31 moving up and down with the lifting mechanism 2, but also providing power for the subsequent pulling of the flipping frame 32 to flip. At this time, the middle of the flipping frame 32 is hinged to the platform 21, enabling the flipping frame 32 to flip around its hinge point on the platform 21. At the same time, a connection block 34 for cooperating with the mold is provided on the flipping frame 32, realizing the cooperation with the mold through the connection block 34, enabling the mold to be installed on the flipping frame 32 through the connection block 34, providing conditions for the subsequent flipping of the mold driven by the flipping frame 32. In addition, one end of the flipping frame 32 is hinged to one end of the pull rod 33, and at the same time, the other end of the pull rod 33 is connected to the telescopic shaft of the telescopic drive 31. When the telescopic shaft of the telescopic drive 31 moves, it can pull one end of the flipping frame 32 to move through the pull rod 33, so that the flipping frame 32 can flip around its hinge point on the platform 21, meeting the use requirement of driving the mold to flip. In addition, the hinge point between the pull rod 33 and the flipping frame 32 can be used to adapt to the angle change after the flipping frame 32 flips, avoiding jamming problems and maintaining the normal working state of the flipping structure.

[0030] More specifically, two sets of lifting mechanisms 2 are provided on the frame 1, and the two sets of lifting structures are respectively arranged at both ends of the frame 1. At the same time, the two sets of lifting mechanisms 2 are arranged on both sides of the mold, enabling corresponding lifting mechanisms 2 to support both sides of the mold, thereby maintaining the stability of the mold during the lifting process, avoiding the problem of the mold tilting, and having better safety.

[0031] Figure 4 It is a structural diagram of the connection block of a preferred embodiment of the present utility model. As Figure 1 andFigure 4 As shown, the connection block 34 provided on the flip frame 32 is a clamping block. Preferably, at least two clamping blocks are provided on the flip frame 32 and are arranged at intervals on the corresponding flip frame 32, so that the same flip frame 32 can have multiple connection blocks 34 to cooperate with the mold, further improving the stability of mold installation. In addition, the clamping block is fixed on the flip frame 32, so that the clamping block is stably installed on the corresponding flip frame 32. At the same time, each clamping block is provided with a bayonet, and a clamping shaft that cooperates with the bayonet is correspondingly provided on the mold, so that the mold can be clamped into the corresponding bayonet through the clamping shaft to realize the connection and installation of the mold and the flip frame 32, providing conditions for the flip frame 32 to drive the mold to flip. It is worth pointing out that a first strip locking groove is opened along one direction on the flip frame 32, and the connecting block 34 is connected to the first strip locking groove by bolts, so that when the bolts are loosened, the connecting block 34 can be moved along the first strip locking groove, thereby adjusting the position of the connecting block 34 on the flip frame 32. At the same time, a second strip locking groove is opened along one direction on the connecting block 34, and the second strip locking groove is arranged perpendicular to the first strip locking groove. Similarly, the bolt can also pass through the second strip locking groove when connected to the first strip locking groove, so that when the bolts are loosened, the position of the connecting block 34 relative to the bolts can be adjusted, that is, the first strip locking groove and the second strip locking groove are used to realize the adjustment of the connecting block 34 to any position in the horizontal plane, thereby meeting the installation requirements of different molds.

[0032] Specifically, the bayonet on the connecting block 34 includes a vertical channel 341 and an inclined channel 342. At this time, the vertical channel 341 is a slot extending vertically downward in the vertical direction, and the opening of the vertical channel 341 is arranged vertically upward, that is, the clamping shaft of the mold can be clamped into the vertical channel 341 through the upper opening of the vertical channel 341. At the same time, the inclined channel 342 is arranged at an angle to the vertical channel 341, and the lower end of the inclined channel 342 is connected to the lower end of the vertical channel 341, so that the clamping shaft in the vertical channel 341 can move into the inclined channel 342. In addition, the upper end of the inclined channel 342 is a closed end, so that the clamping shaft moved into the inclined channel 342 can be restricted from continuing to move, thereby preventing the clamping shaft from accidentally escaping from the bayonet, and providing higher safety.

[0033] More specifically, the jacking mechanism 2 further includes a guiding and lifting mechanism 24 to improve the stability of the moving seat 23 during lifting and lowering, and also provide drive for the lifting and lowering movement of the moving seat 23. At this time, the guiding and lifting mechanism 24 includes a guiding and lifting rod 241 and a sliding sleeve 242. During installation, the guiding and lifting rod 241 is arranged in the vertical direction to meet the lifting and lowering movement requirements of the moving seat 23. Moreover, one end of the guiding and lifting rod 241 is connected to the carrier 21, so that when the carrier 21 is driven by the lifting drive 22 to lift and lower, the carrier 21 can drive the guiding and lifting rod 241 to lift and lower. At the same time, the other end of the guiding and lifting rod 241 is connected to the moving seat 23, so as to pull the moving seat 23 to lift and lower through the guiding and lifting rod 241. In addition, the sliding sleeve 242 is installed on the frame 1, and the guiding and lifting rod 241 is slidably arranged in the sliding sleeve 242. The sliding sleeve 242 provides guidance for the movement of the guiding and lifting rod 241, thus maintaining the stability of the moving plate 35 during lifting and lowering.

[0034] More specifically, the moving seat 23 is arranged below the frame 1 and the carrier 21. At the same time, the carrier 21 is located above the frame 1, and the guiding and lifting rod 241 passes through the frame 1. That is, in the vertical direction, the carrier 21 is located above the frame 1, which facilitates the subsequent mating installation of the turning frame 32 installed on the carrier 21 and the mold. At the same time, the moving seat 23 is located below the frame 1, so that the telescopic drive 31 and other structures of the turning mechanism 3 can be located in the lower space of the frame 1, avoiding occupying the space for processing above the frame 1, and making the space utilization more reasonable.

[0035] More specifically, the jacking mechanism 2 further includes an auxiliary guiding mechanism 25. At this time, the auxiliary guiding mechanism 25 includes a plurality of guiding rods 251 and guiding sleeves 252. During installation, a plurality of guiding sleeves 252 are installed on the moving seat 23, so that the plurality of guiding sleeves 252 can follow the moving seat 23 to lift and lower. At the same time, a guiding rod 251 is slidably arranged in each guiding sleeve 252. Moreover, one end of the guiding rod 251 is fixed to the frame 1, realizing the stable installation of the guiding rod 251. At the same time, the guiding sleeve 252 can stably slide along the axial direction of the guiding rod 251. That is, the guiding rod 251 and the guiding sleeve 252 provide stable guidance for the lifting and lowering of the moving seat 23, improving the stability of the moving seat 23 during lifting and lowering.

[0036] More specifically, the auxiliary guiding mechanism 25 further includes a connecting plate 253. At this time, the connecting plate 253 is arranged at one end of a plurality of guiding rods 251 away from the connecting frame 1, and the corresponding ends of each guiding rod 251 are fixedly connected to the connecting plate 253. The plurality of guiding rods 251 are formed into a whole through the connecting plate 253, that is, one end of the plurality of guiding rods 251 forms a whole through the frame 1, and the other end of the plurality of guiding rods 251 forms a whole through the connecting plate 253. Thus, both ends of the plurality of guiding rods 251 can be stably connected and supported, improving the installation stability of the guiding rods 251, with a better guiding effect, and avoiding the problem of jamming caused by the inclination of the guiding rods 251. At the same time, the connecting plate 253 is located below the moving seat 23, avoiding the problem that the connecting plate 253 affects the lifting of the moving seat 23, and the structural design is more reasonable.

[0037] More specifically, the flipping mechanism 3 further includes a moving plate 35. At this time, the moving plate 35 is installed on the telescopic shaft of the telescopic driver 31, so that the moving plate 35 moves along with the telescopic shaft of the telescopic driver 31. At the same time, one end of the moving plate 35 is connected to the end of the pull rod 33 away from the flipping frame 32. When the moving plate 35 moves along with the telescopic shaft of the telescopic driver 31, the moving plate 35 can drive the pull rod 33 to move, thereby realizing the flipping of the flipping frame 32. That is, the moving plate 35 serves as a transfer structure between the pull rod 33 and the telescopic shaft of the telescopic driver 31, and can adapt to the use requirements of different installation positions between the pull rod 33 and the telescopic shaft of the telescopic driver 31, ensuring that the pull rod 33 and the telescopic shaft of the telescopic driver 31 can be power-connected. It should be noted that when there are two sets of the jacking mechanism 2, there are also two sets of the flipping frame 32 and the pull rod 33 of the flipping mechanism 3. Moreover, each flipping frame 32 corresponds to the platform 21 of a set of the jacking mechanism 2, each pull rod 33 corresponds to a flipping frame 32. At the same time, the middle part of the moving plate 35 is connected to the telescopic shaft of the telescopic driver 31, and both ends of the moving plate 35 are respectively connected to a pull rod 33, and the two pull rods 33 are respectively connected to the two flipping frames 32, realizing that one telescopic driver 31 drives the two flipping frames 32 to flip synchronously. This not only simplifies the structural layout, reduces costs, but also ensures the synchronous flipping of the two flipping frames 32, improving the stability during the flipping process.

[0038] Figure 5 It is a schematic diagram of the cooperation between the platform and the flipping frame of a preferred embodiment of the present invention. As Figure 1 and Figure 5As shown, the carrier 21 of the lifting mechanism 2 further includes a bottom support 211 and side plates 212. At this time, the bottom support 211 is horizontally arranged, and the bottom of the bottom support 211 is connected to the drive shaft of the lifting driver 22, so that the lifting driver 22 can drive the bottom support 211 to lift. At the same time, a side plate 212 is arranged along the vertical direction on one side of the bottom support 211, so that the base and the side plate 212 form an "L"-shaped structure, that is, a side mounting structure is formed on one side of the bottom support 211 through the side plate 212. In addition, the turning frame 32 further includes a bottom plate 321 and a turning plate 322. During installation, the bottom plate 321 and the turning plate 322 are perpendicular to each other, and one side of the bottom plate 321 is fixedly connected to one end of the turning plate 322, so that the external shape of the turning frame 32 is similar to the external shape of the carrier 21. At this time, the turning plate 322 is arranged along the vertical direction and attached to the side plate 212. Moreover, the turning plate 322 and the side plate 212 are hinged through a bearing and a rotating shaft, so that the turning plate 322 can rotate relative to the side plate 212. And when the turning plate 322 rotates relative to the side plate 212, the bottom plate 321 and the bottom support 211 are stacked or arranged at an angle. That is, when the turning plate 322 is not turned, the bottom plate 321 is stacked on the bottom support 211, so that the bottom support 211 can support the bottom plate 321, reducing the burden on the hinge between the turning plate 322 and the side plate 212. And after the turning plate 322 is turned, the base can be arranged at an angle with the bottom support 211, ensuring that the turning frame 32 rotates relative to the carrier 21. In addition, the connecting block 34 is installed on the bottom plate 321, that is, the installation and support of the mold are realized through the bottom plate 321. At the same time, one end of the pull rod 33 is connected to one end of the turning plate 322, ensuring that the pull rod 33 can pull the turning plate 322 to rotate relative to the side plate 212. It is worth pointing out that one end of the bottom support 211 close to the hinge of the turning plate 322 and the side plate 212 is provided with an avoidance inclined surface, so that when the bottom plate 321 and the bottom support 211 are arranged at an angle due to the rotation of the turning plate 322 relative to the side plate 212, the avoidance inclined surface can provide an avoidance space for the deflection of the bottom plate 321, thus preventing the problem that the side edge of the bottom support 211 abuts against the bottom plate 321 and restricts the turning of the bottom plate 321, and the structural design is more reasonable.

[0039] The ejecting and flipping assembly of the injection mold provided in this embodiment includes a frame 1, a jacking mechanism 2 and a flipping mechanism 3. By arranging the jacking mechanism 2 on the frame 1, and at the same time, a flipping mechanism 3 is arranged on the jacking mechanism 2, and the flipping mechanism 3 is connected to the mold through a connecting block 34. The mold can be jacked up to a predetermined height by the jacking mechanism 2, so that the mold is separated from the original structure and a space for subsequent flipping of the mold is reserved. Then, the flipping mechanism 3 drives the mold to flip a predetermined angle, so that the mold can be flipped into a predetermined space, which facilitates the operator to take out the product, replace and clean the mold, saving time and effort, and having a simple structure and convenient operation. In addition, it can ensure that the operation process of the operator is within a safe area, avoiding potential safety hazards caused by the operator's hand reaching into the die closing mechanism, and having a higher safety guarantee.
