[0034] This utility model proposes a mold opening device, which aims to provide a semi-automatic mold opening device, which only requires one person to operate to realize mold opening and mold cleaning, thus reducing labor costs. Figures 1 to 4 This is a structural diagram of an embodiment of the mold opening device provided by the present invention.

[0035] Please refer to Figures 1 to 4The utility model proposes a mold opening device 100, including a transmission frame 1, a rotating mechanism 2 and a mold opening mechanism 3. The transmission frame 1 is provided with a plurality of parallel conveying rollers 11, and the upper parts of the plurality of conveying rollers 11 form a conveying plane. Columns 12 are respectively provided on both sides of the transmission frame 1. The rotating mechanism 2 includes a rotating plate 21. The two ends of the rotating plate 21 form a first rotating shaft 212. The two first rotating shafts 212 are respectively rotated on the two columns 12. The rotating plate 21 is located between the two columns 12. The mold opening mechanism 3 includes a first cylinder 31 and a support frame 32. The first cylinder 31 is provided with a rotating plate 21. The support frame 32 is provided at the driving end of the first cylinder 31. The support frame 32 is used to install the upper mold 200.

[0036] In the technical solution of the present invention, a mold opening device 100 and a carbon fiber wheel rim mold are proposed, wherein the mold opening device 100 includes a transmission frame 1, a rotating mechanism 2 and a mold opening mechanism 3. The transmission frame 1 is provided with a plurality of parallel conveying rollers 11, and the upper parts of the plurality of conveying rollers 11 form a conveying plane. The transmission frame 1 is used to convey the mold. Two sides of the transmission frame 1 are respectively provided with columns 12, and a rotatable rotating plate 21 is provided on the column 12. The mold opening mechanism 3 is provided on the rotating plate 21. When performing the mold opening operation, the mold is placed under the rotating plate 21, and the rotating plate 21 is rotated so that the driving end of the first cylinder 31 on the rotating plate 21 faces the upper mold 200, and the upper mold 200 is connected to the driving end of the first cylinder 31. The first cylinder 31 is controlled to contract and drive the upper mold 200 and the lower mold 300 to open the mold, and the upper mold 200 is lifted upward. The rotating plate 21 can be rotated manually or automatically to clean the mold cavity. During the operation, only one person is needed to complete the mold opening and cleaning operations, thereby reducing labor costs.

[0037] In order to facilitate the staff to clean the upper mold 200 cavity and demould the product, it is usually necessary to rotate the upper mold 200 after the upper mold 200 and the lower mold 300 are opened so that the cavity of the upper mold 200 faces outward. In one embodiment of the present invention, considering the large mass of the mold, the support frame 32 is automatically driven to rotate. It should be noted that the support frame 32 can be pneumatically driven or electrically driven. The present invention does not limit this. In this embodiment of the present invention, the rotating mechanism 2 also includes a second cylinder 22, which is hinged to the transmission frame 1. A transmission rod 23 is provided at one end of the rotating plate 21, and the transmission rod 23 is fixedly connected to the rotating plate 21. That is, when the transmission rod 23 is driven to rotate, the rotating plate 21 will rotate synchronously therewith, and the transmission rod 23 has a free end, and the free end of the transmission rod 23 is driven and connected to the driving end of the second cylinder 22, so that the transmission rod 23 can rotate around the axis of the rotating shaft under the driving action of the second cylinder 22, and since the transmission rod 23 is fixedly assembled with the rotating shaft, the torque of the transmission rod 23 will be transmitted to the rotating plate 21 to rotate the rotating plate 21. The upper mold 200 is driven to rotate by pneumatic means, which can save labor and labor, and the use of an automated method for flipping greatly reduces its safety hazards compared to manual flipping. Manual flipping is easy to cause the mold to injure the staff due to the large mass of the upper mold 200 in the event of a mistake in force control. The use of an automated method not only improves production efficiency but also reduces safety hazards.

[0038] In order to facilitate the disassembly of the transmission rod 23 and thus realize the maintenance and replacement of the second cylinder 22 or the rotating plate 21, the transmission rod 23 is formed with a mounting hole, and the first rotating shaft 212 is inserted into the mounting hole. The other end of the transmission rod 23 away from the mounting hole is provided with a second rotating shaft 231 and is hinged to the second cylinder 22 through the second rotating shaft 231. The circumference of the first rotating shaft 212 is provided with an insertion protrusion 213. For details, please refer to Figure 3 Correspondingly, a plug-in hole is provided on the inner wall of the mounting hole, and the plug-in protrusion 213 is plugged into and limited by the plug-in hole, so that the transmission rod 23, the first rotating shaft 212 and the rotating plate 21 can rotate synchronously.

[0039] Since the transmission rod 23 is a non-retractable structure, the second cylinder 22 will also be stretched and deformed when the transmission rod 23 is driven to rotate. In view of this, a mounting platform 13 is provided on one side of the transmission frame 1. For details, please refer to Figure 2 The mounting platform 13 is provided with an articulated seat 14, and the body of the second cylinder 22 is rotatably arranged on the transmission frame 1 through the articulated seat 14. The design of the mounting platform 13 can avoid the second cylinder 22 being directly set on the conveying plane to affect the conveying of the mold, making the overall structure more reasonable.

[0040] After the mold is opened, it is necessary to place the mold on the conveying roller 11 below the rotating plate 21, and control the first cylinder 31 to extend so that the support frame 32 at the driving end of the first cylinder 31 abuts against the top surface of the upper mold 200, lock the bolts in the locking holes 322 of the support frame 32, and make each bolt pass through the locking holes 322 and be threadedly connected with the hole on the top surface of the upper mold 200, thereby fixing the upper mold 200 and the support frame 32, and then control the first cylinder 31 to retract so that the support frame 32 drives the upper mold 200 to lift upward, thereby separating the upper mold 200 from the lower mold 300. It should be noted that the support frame 32 can be a straight plate, or a Y-shaped frame composed of three support arms 321, or a cross-shaped frame composed of four support arms 321. The present invention is not limited to this. In one embodiment of the present invention, the support frame 32 adopts a cross-shaped frame. For details, please refer to Figure 1 The cross-shaped bracket has good installation stability and can ensure that the force on each arm 321 is uniform. Furthermore, the locking hole 322 is a waist-shaped hole, which can be adapted to molds of different specifications, thereby improving its universality.

[0041] When the first cylinder 31 is retracted and extended, it is necessary to ensure that the moving trajectory of the support frame 32 remains unchanged. To this end, the rotating plate 21 is provided with two guide holes 211, and the two guide holes 211 are respectively arranged on both sides of the first cylinder 31. The rotating mechanism 2 also includes two guide rods 33, and the two guide rods 33 are movably passed through the two guide holes 211, so that the support frame 32 can rise and fall along a predetermined trajectory.

[0042] In the present invention, the mold is transported to the bottom of the rotating plate 21 by the conveying roller 11 so as to carry out the next step of mold opening operation. In order to limit the mold, the conveying frame 1 is provided with a limiting plate 15. For details, please refer to Figure 4 The limiting plate 15 is arranged along the axial direction of the conveying roller 11, and limiting protrusions 151 are provided at both ends of the limiting plate 15. The limiting protrusions 151 are used to abut against the lower mold 300 to stop the lower mold 300.

[0043] The present invention also proposes a carbon fiber wheel rim mold, which includes an upper mold 200, a lower mold 300, a core mold and a mold opening device 100. The lower mold 300 is arranged on the conveying roller 11, and the upper mold 200 is connected to the support frame 32. The specific structure of the mold opening device 100 refers to the above embodiment. Since this carbon fiber wheel rim mold adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0044] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
