Description

Technical Field

[0001] The utility model relates to the technical field of artificial stone product production, and particularly relates to a mold flipping mechanism and a mold clamping device including the mold flipping mechanism. Background Art

[0002] When forming artificial stone products, processes such as spraying gel coat, drying, mold clamping, casting, and demolding are required. Among them, spraying gel coat means spraying glue on the inner surface of the mold to form a layer of gel coat on the inner surface of the mold. After drying the sprayed mold, the upper mold and the lower mold need to be installed together to form a complete mold, which is called mold clamping.

[0003] When spraying glue and drying the mold, the upper mold and the lower mold are generally placed on a supporting structure and in a posture with the opening facing upward. Therefore, when clamping the mold, the upper mold needs to be flipped over and moved above the lower mold before the upper mold and the lower mold can be installed to form a mold. In the prior art, this process is generally carried out manually. Since the mold clamping process is after the drying process, it is necessary to wait for a period of time for the mold to cool down before manual mold clamping, which is not conducive to improving production efficiency.

[0004] Later, in order to facilitate mold clamping, a flipping mechanism appeared, which includes a clamp, a clamp guide rail, and a 180-degree reciprocating rotation mechanism. When this flipping mechanism operates, the clamp moves along the clamp guide rail, then clamps the mold, and then uses the 180-degree reciprocating rotation mechanism to flip the clamp together with the mold clamped by the clamp. This flipping mechanism can perform mold clamping without waiting for the mold to cool down, which is conducive to improving production efficiency. However, in this flipping mechanism, the 180-degree reciprocating rotation mechanism generally uses a rotary motor, and the rotary motor has disadvantages such as insufficient steering force, easy to malfunction, and high cost. Moreover, the volume and mass of some artificial stone products are relatively large, such as artificial stone bathtubs. Correspondingly, the volume and mass of the molds used to produce these artificial stone products are also relatively large. When flipping these molds, if a rotary motor is still used for mold flipping, situations such as incomplete flipping are likely to occur, and even the mold may be damaged.

[0028] like Figures 1 to 5As shown, a mold flipping mechanism includes a frame 1 and a clamping device 2 and a flipping device 3 arranged thereon; the clamping device 2 includes a clamping frame 21, a clamping arm assembly 22 and a clamping drive device 23, the clamping arm assembly 22 includes at least two clamping arms 221, the clamping arms 221 are slidably connected to the clamping frame 21, and the clamping arms 221 are rotatably connected with clamping claws 24, the clamping drive device 23 is transmission-connected to the clamping arm assembly 22, and the clamping drive device 23 is used to drive the two clamping claws 24 to move closer to or away from each other to clamp or release the mold 10; the flipping device 3 includes a transmission-connected linear drive 31 and a transmission gear structure 32, the transmission gear structure 32 is transmission-connected to the clamping claws 24, and the output end of the linear drive 31 can drive the clamping claws 24 to rotate through the transmission gear structure 32 to flip the mold 10.

[0029] The linear drive 31 and the transmission gear structure 32 are used to drive the clamping jaws 24 to rotate, thereby driving the mold 10 clamped by the clamping jaws 24 to flip. The linear drive 31 can provide a large driving force, and the driving force in the linear direction is converted into a steering force acting on the clamping jaws 24 through the transmission gear structure 32, which is conducive to improving the stability of the flipping of the mold 10, expanding the application range of the flipping device 3 and the mold flipping mechanism, and reducing the possibility of damage to the mold 10 during flipping, thereby improving production efficiency and economic benefits.

[0030] The mold 10 referred to in this embodiment includes an upper mold 101 , a lower mold 102 , and a complete mold 10 formed by combining the upper mold 101 and the lower mold 102 .

[0031] In this embodiment, the mold turning mechanism acts on the upper mold 101. In other embodiments, the lower mold 102 can also be used as the mold turning mechanism.

[0032] The mold flipping mechanism in this embodiment can be used in the mold closing process of the upper mold 101 and the lower mold 102, and is also suitable for the mold opening process of separating the upper mold 101 and the lower mold 102.

[0033] In some specific embodiments, reference Figures 2 to 4 The transmission gear structure 32 includes a driving gear 321 and a driven gear 322 that are meshed and connected. The driving gear 321 and the driven gear 322 are both rotatably connected to the clamping arm 221. The output end of the linear drive 31 is connected to the driving gear 321 through a transmission rod 33. The transmission rod 33 is fixedly connected to the driving gear 321 and extends radially along the driving gear 321. The output end of the linear drive 31 is rotatably connected to the transmission rod 33, and its rotation axis is parallel to the rotation axis of the driving gear 321.

[0034] Specifically, the diameter of the driving gear 321 is larger than that of the driven gear 322. The linear driver 31 drives the driving gear 321 to rotate, thereby driving the driven gear 322 to rotate. If the transmission gear structure 32 only includes one gear, since the output end of the linear driver 31 can only perform linear motion, it is impossible to directly drive the gear to rotate 180°. However, through the cooperation of the driving gear 321 and the driven gear 322, the driven gear 322 and the clamping jaw 24 can be rotated 180°, realizing the process of converting the linear driving force into the steering force. Moreover, the output end of the linear driver 31 can realize the 180° rotation of the driven gear 322 and the clamping jaw 24 through a relatively small movement, thereby realizing the flipping of the mold 10, which is beneficial to prolonging the service life of the linear driver 31 and the mold flipping mechanism.

[0035] In some specific embodiments, reference Figure 3 and Figure 4 One end of the linear drive 31 away from its output end is rotatably connected to the clamping arm 221 , and its rotation axis is parallel to the rotation axis of the driving gear 321 .

[0036] Specifically, the linear drive 31 is located on the upper side of the driving gear 321 .

[0037] When the driving gear 321 rotates, the end of the transmission rod 33 away from the driving gear 321, that is, the end rotatably connected to the output end of the linear driver 31, moves along an arc. Therefore, correspondingly, the end of the linear driver 31 away from its output end is rotatably connected to the clamping arm 221, so that when the linear driver 31 drives the driving gear 321 to rotate, the position of its output end can match the moving track of the end of the transmission rod 33 away from the driving gear 321 in real time, making the driving process smooth, which is conducive to improving production efficiency, reducing the failure rate of the linear driver 31 and the mold turning mechanism, and extending the service life.

[0038] In some specific embodiments, reference Figures 1 to 4 The linear drive 31 includes a flip drive cylinder 311.

[0039] In some other embodiments, the linear drive 31 may be a linear drive device such as an oil cylinder or a linear motor.

[0040] In some specific embodiments, reference Figure 2 One end of the clamping arm 221 is connected to the clamping frame 21, and the other end of the clamping arm 221 is provided with a mounting tube 2211. The clamping claw 24 is provided with a rotating rod 241, and the other end of the rotating rod 241 is provided with a driven gear 322. The rotating rod 241 is inserted into the mounting tube 2211 and can rotate in the mounting tube 2211.

[0041] Specifically, the mounting tube 2211 is disposed at the lower end of the clamping arm 221 , the mounting tube 2211 extends in the horizontal direction, and the driving gear 321 is located beside the clamping arm 221 .

[0042] Furthermore, the extension direction of the mounting cylinder 2211 , the extension direction of the rotating rod 241 , the rotation axis of the driven gear 322 , the rotation axis of the driving gear 321 and the rotation axis of the linear drive 31 are all consistent with the extension direction of the clamping arm slide rail 211 .

[0043] In some specific embodiments, reference Figure 2 The clamping drive device 23 includes two clamping drive cylinders 231, which are respectively connected to the two clamping arms 221. The clamping frame 21 is provided with a clamping arm slide rail 211, and the clamping arm 221 is clamped on the clamping arm slide rail 211 and can move along the clamping arm slide rail 211.

[0044] Specifically, the piston rod of the clamping drive cylinder 231 extends in the direction of the clamping arm slide rail 211. When clamping the mold 10, the piston rod of the clamping cylinder is retracted, and the two clamping jaws 24 are close to each other to clamp the mold 10; when releasing the mold 10, the piston rod of the clamping cylinder is extended, and the two clamping jaws 24 are away from each other to release the mold 10.

[0045] In some specific embodiments, reference Figure 1 The mold turning mechanism further includes a lifting device 4 , the lifting device 4 includes a lifting drive device 41 , and the clamping frame 21 is arranged on the output end of the lifting drive device 41 .

[0046] Specifically, the lifting drive device 41 includes a lifting drive cylinder 411 , a piston rod of which faces downward, and the clamping frame 21 is fixedly disposed on the piston rod of the lifting drive cylinder 411 .

[0047] During operation, the lifting drive cylinder 411 drives the clamping frame 21 to descend and approach the mold 10 below, and then the clamping device 2 clamps the mold 10, and the lifting drive cylinder 411 drives the clamping part to rise to make room for flipping the mold 10, and finally the flipping device 3 flips the mold 10.

[0048] In some other embodiments, the lifting drive device 41 may be a drive device such as an oil cylinder, as long as it can drive the clamping frame 21 to rise and fall.

[0049] In some specific embodiments, reference Figure 1The lifting device 4 also includes a lifting seat 42, a lifting drive device 41 is arranged on the lifting seat 42, a lifting seat slide rail 43 is provided on the frame 1, the lifting seat 42 is clamped on the lifting seat slide rail 43 and can move along the lifting seat slide rail 43, the lifting seat 42 and the clamping arm 221 can both move in the horizontal direction, and the moving direction of the lifting seat 42 is perpendicular to the moving direction of the clamping arm 221.

[0050] Specifically, the clamping arm slide rail 211 and the lifting seat slide rail 43 both extend in the horizontal direction, but the extension direction of the clamping arm slide rail 211 is perpendicular to the extension direction of the lifting seat slide rail 43, so that the clamping frame 21 can be moved up and down, left and right, and front and back. During the production process, the position of the clamping frame 21 can be adjusted according to actual needs, which is conducive to improving production efficiency and expanding the application range of the mold flipping mechanism.

[0051] In some specific embodiments, reference Figure 1 A control frame 5 is also provided on the frame 1 , and a controller 51 is provided on the control frame 5 . The lifting drive cylinder 411 , the clamping drive cylinder 231 and the flipping drive cylinder 311 are all communicatively connected with the controller 51 .

[0052] This embodiment also discloses a mold clamping device, referring to Figure 5 , including the above-mentioned mold turning mechanism.

[0053] In some specific embodiments, reference Figure 5 The mold turning mechanism also includes a lifting device 4, which includes a lifting drive device 41. The clamping frame 21 is arranged on the output end of the lifting drive device 41, and a conveying device 20 for conveying the mold 10 is arranged below the clamping frame 21.

[0054] During operation, the conveying device 20 first conveys the upper mold 101 to the bottom of the clamping frame 21, and then the lifting device 4 drives the clamping frame 21 to descend, the clamping device 2 clamps the upper mold 101, and then the lifting device 4 drives the clamping frame 21 to rise, and the flipping device 3 flips the upper mold 101. During the process of clamping and flipping the upper mold 101, the conveying device 20 conveys the lower mold 102 to the top of the upper mold 101. After the upper mold 101 is flipped, the lifting device 4 lowers the upper mold 101 and places it on the lower mold 102, and the staff installs and connects the upper mold 101 and the lower mold 102.
