The driving gear 31421 is rotatably connected to the main arm body 31321, and the driven gear 31422 is arranged at the end of the clamping arm 31322 away from the clamping jaw 31323. The driving gear 31421 and the driven gear 31422 are meshed and connected. A transmission rod is arranged on the piston rod of the mold closing and flipping cylinder 3141. One end of the transmission rod is connected to the piston rod, and the other end is connected to the driving gear 31421. When the piston rod moves up and down, the driving gear 31421 will rotate synchronously, and then drive the clamping arm 31322 to rotate through the driven gear 31422, so as to flip the upper mold clamped by the two clamping arms 31322.

[0058] During mold closing, the operator moves the upper mold onto the conveying rail 1611 below the clamping frame 3131, and then the lifting cylinder drives the clamping frame 3131 to descend until the two clamping jaws 31323 are located on both sides of the upper mold. The two clamping arms 3132 move closer synchronously, so that after the two clamping jaws 31323 clamp the upper mold, the lifting cylinder drives the clamping frame 3131 to rise, so that the upper mold is separated from the conveying moving part 10. Subsequently, the mold closing and flipping cylinders 3141 on the two main arm bodies 31321 drive the two clamping jaws 31323 to flip through the driving gear 31421 and the driven gear 31422, thereby driving the upper mold to flip. Finally, the operator moves the lower mold below the upper mold, and the lifting cylinder drives the clamping frame 3131 to descend until the upper mold descends to the position where it is fitted and installed with the lower mold, and the operator fixes the upper mold and the lower mold to complete mold closing.

[0059] Furthermore, a lifting seat slide rail 31111 is arranged on the mounting frame 31111. The lifting seat slide rail 31111 extends in the horizontal direction and is perpendicular to the clamping arm slide rail 31311. The lifting seat 3122 is clamped on the lifting seat slide rail 31111 and can move on the lifting seat slide rail 31111. During mold closing, the lifting seat 3122 can move on the lifting seat slide rail 31111 for position adjustment, so that the mold closing clamping device 313 can clamp the corresponding position of the upper mold more accurately, and can also improve the matching accuracy for the installation of the upper mold and the lower mold.

[0060] In some other embodiments, the mold closing and flipping device 314 also uses a motor as the driving device, as long as it can flip the upper mold clamped by the clamping arm 3132.

[0061] In some specific embodiments, the molding device 4 includes a pouring device 41 for injecting a molding material into the mold 30. The conveying line 1 includes a first curing section 13. The pouring device 41 and the first curing section 13 are arranged in sequence along the conveying line 1. A first curing conveying driving device 131 is provided on the first curing section 13 for driving the conveying moving member 10 and the mold 30 thereon to move along the first curing section 13 to cure the molding material in the mold 30.

[0062] Specifically, the first conveying driving device 20 is provided on the first curing section 13, and the first conveying driving device 20 provided on the first curing section 13 is referred to as the first curing conveying driving device 131.

[0063] During curing, since the temperature of the conveying moving member 10 and the mold 30 is relatively high, the first curing conveying driving device 131 is used to maintain the conveyance of the mold 30 on the conveying line 1, and while cooling, the mold 30 is conveyed to the equipment corresponding to the next process, which is beneficial to shortening the production time and further improving the production efficiency.

[0064] In some specific embodiments, the artificial stone product is one of an artificial stone washbasin, an artificial stone toilet, an artificial stone bathtub, an artificial stone countertop, an artificial stone shower tray, and artificial stone furniture.

[0065] In some specific embodiments, referring to Figure 1 , the conveying line 1 further includes a cleaning section 11, and the cleaning section 11 is located on the front side of the gel coat spraying section.

[0066] Specifically, the conveying line 1 is a circulating line, and the mold 30 passing through the demolding section 14 will return to the gel coat spraying section again. However, before the mold 30 returns to the gel coat spraying section again, it will first pass through the cleaning section 11. In the cleaning section 11, the staff will clean the demolded mold 30, wax the mold 30 after cleaning, and then send the mold 30 to the gel coat spraying section.

[0067] In some specific embodiments, referring to Figure 1 , the conveying line 1 includes a glue spraying section 121, a gel coat defoaming section 1214, and a drying section 122 arranged in sequence. The glue spraying section 121 includes a first glue spraying section 1211 and a second glue spraying section 1212 arranged in sequence. The gel coat spraying device 2 includes a glue spraying device 21. The first glue spraying section 1211 passes through the glue spraying device 21, and a glue spraying conveying driving device 15 is provided on the first glue spraying section 1211. The second glue spraying section 1212 is used for manual supplementary glue spraying.

[0068] Specifically, the glue spraying device 21 includes a glue spraying chamber 211 and a glue spraying machine 212 disposed inside the glue spraying chamber 211. The glue spraying conveying drive device 15 on the first glue spraying section 1211 passes through the glue spraying chamber 211, conveys the mold 30 from one end of the glue spraying chamber 211 into the glue spraying chamber 211, and the glue spraying machine 212 sprays gel coat on it, and then conveys the mold 30 out of the glue spraying chamber 211.

[0069] After the glue spraying machine 212 sprays gel coat on the mold 30, the mold 30 enters the second glue spraying section 1212, and manual glue patching is performed by the staff to ensure the quality of the gel coat spraying.

[0070] After the mold 30 passes through the second glue spraying section 1212, it will enter the gel coat defoaming section 1214. Since there is a temperature difference between the sprayed gel coat and the mold 30, bubbles may be generated after the gel coat is sprayed. After the mold 30 enters the gel coat defoaming section 1214, it will stand still for a period of time, such as 10 minutes, waiting for the temperature difference between the gel coat and the mold 30 to narrow, so that the gel coat adheres more closely to the mold 30, eliminating bubbles and ensuring the quality of the gel coat spraying.

[0071] Furthermore, for the production of artificial stone products such as artificial stone wash basins with overflow holes, the conveyor line 1 further includes an overflow part installation section 1213 disposed between the second glue spraying section 1212 and the gel coat defoaming section 1214. After the mold 30 enters the overflow part installation section 1213 from the second glue spraying section 1212, the staff will install an overflow part on the mold 30, so that the produced sanitary ware has an overflow hole.

[0072] In some specific embodiments, referring to Figure 1 , the conveyor line 1 includes a demolding section 14. The demolding section 14 includes a mold opening section 141, a second curing section 142, and a product taking-out section 143 arranged in sequence. The mold opening device 51 corresponds to the position of the mold opening section 141. A second curing conveying drive device 1421 is provided on the second curing section 142. The second curing conveying drive device 1421 is used to drive the conveying moving part 10 and the mold 30 thereon to move along the second curing section 142 for secondary curing. The demolding device 5 includes a mold opening device 51, and the product taking-out section 143 is used to take out the product from the mold 30.

[0073] Specifically, the mold opening device 51 has the same structure as the mold clamping device 31. After the staff releases the fixing structure between the upper mold and the lower mold, the mold opening device 51 clamps, lifts, and flips the upper mold, and finally places the upper mold on the conveyor line 1, while the lower mold and the product thereon will be sent to the product taking-out section 143. The staff takes out the product from the lower mold and performs simple cleaning processes such as edging on the product.

[0074] The above-mentioned first conveying driving device 20 is provided on the second curing section 142. The first conveying driving device 20 provided on the second curing section 142 is called the second curing conveying driving device. The second curing conveying driving device 1421 is used to drive the conveying moving member 10 and the mold 30 and the product thereon to move on the second curing section 142.

[0075] After the mold 30 is poured by the pouring device 41 and passes through the first curing section 13, the temperature of the molding material drops and preliminary curing is carried out. Finally, the upper mold is removed by the mold opening device 51. After the preliminarily cured molded product is exposed, the mold 30 then moves on the second curing section 142 for secondary curing to obtain the final molded product, ensuring the curing effect and improving the molding quality. Finally, the product is sent to the product taking-out section 143.

[0076] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
