DETAILED DESCRIPTION
[0021] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 6As shown, this embodiment provides a resin craft casting mold opening device, including a mold rotation system 1, a mold clamping system 2, a mold bracket 3, an inertial vibration system 4 and an inner mold 5. The mold clamping system 2 is installed on the mold rotation system 1. The mold clamping system 2 is used to clamp the mold bracket 3. The mold bracket 3 is used to clamp the inner mold 5. Because the inner mold 5 is made of silicone and the material is soft, a hard mold bracket 3 is required to be provided for support. The inertial vibration system 4 includes an inertial flywheel 41 and a tracking vibration plate 42. The inertial flywheel 41 is rotatably installed on the mold rotation system 1 through a bearing. A plurality of vibration cones 411 are provided on the inertial flywheel 41. The mold rotation system 1 is When rotating, the inertial flywheel 41 will rotate relative to the mold rotating system 1 under the action of its own inertia. A vibration guide groove 421 is provided on the lower side of the tracking vibration plate 42 for each vibration cone 411 to slide. A plurality of vibration grooves 422 are provided in each vibration guide groove 421. Each vibration groove 422 is adapted to the corresponding vibration cone 411. Since the mold rotating system 1 clamps the mold bracket 3, when the inertial flywheel 41 rotates relative to the mold rotating system 1, the inertial flywheel 41 drives the vibration cone 411 to shift relative to the vibration groove 422, thereby generating vibration. In this way, the liquid material in the inner mold 5 is vibrated while rotating, so that the liquid silicone that has not yet been fully solidified is evenly distributed before solidification.
[0022] The working principle of the inertial flywheel 41 and the tracking vibration plate 42 is that the inertial flywheel 41 pushes the tracking vibration plate 42 to the lower side of the mold support 3, so that the mold support 3 is not only clamped by the mold clamping systems 2, but also pushed by the tracking vibration plate 42. When the mold rotation system 1 drives the mold support 3 to rotate, the inertial flywheel 41 rotates relative to the mold support 3 under the action of its own inertia, and the vibration cones 411 on the inertial flywheel 41 enter and leave the vibration groove 422 in turn, so that the tracking vibration plate 42 and the mold support 3 fitted with the tracking vibration plate 42 vibrate, thereby enhancing the fluidity of the uncured silicone and facilitating the uniform distribution of the uncured silicone in the inner mold 5.
[0023] It is worth noting that in the process where each vibration cone 411 successively enters and leaves the vibration groove 422, causing the tracking vibration plate 42 and the mold bracket 3 that is in contact with the tracking vibration plate 42 to vibrate, if no measures are taken, the tracking vibration plate 42 may cause the mold bracket 3 to deform and affect the size of the final product. In order to solve this problem, a buffering mechanism described below must be provided to avoid possible deformation of the mold bracket 3.
[0024] Therefore, the tracking vibration plate 42 has an elastic silicone column 412, and each vibration cone 411 is installed on the elastic silicone column 412. The purpose of setting the elastic silicone column 412 is to provide a descending space for the vibration action of the vibration cone 411 to avoid interference, or to prevent the vibration groove 422 from getting stuck in the inertia flywheel 41, and at the same time avoid deformation of the mold bracket 3.
[0025] Specifically, rubber is laid on the top of the tracking vibration plate 42 to prevent the tracking vibration plate 42 and the mold support 3 from sliding relative to each other, thereby ensuring that vibration occurs reliably.
[0026] Specifically, the mold rotation system 1 includes a swivel support arm 11, a flip motor 12 and a flip frame 13. The swivel support arm 11 is externally connected to the swivel motor, and the swivel support arm 11 is installed at the output end of the swivel motor. The swivel motor (not shown in the figure) drives the swivel support arm 11 to rotate. The flip motor 12 is installed at the end of the swivel support arm 11, and the flip frame 13 is installed at the output end of the flip motor 12. The flip motor 12 drives the flip frame 13 to flip. The mold clamping system 2 and the inertial vibration system 4 are both installed on the flip frame 13, and the flip frame 13 is used to clamp the mold bracket 3.
[0027] Specifically, the mold clamping system 2 includes a plurality of mold clamping devices 21. At least three mold clamping devices 21 are required to ensure the stability of the clamping of the mold support 3. Each mold clamping device 21 includes a clamping lifting support 211 and a clamping assembly 212. The clamping assembly 212 is installed on the clamping lifting support 211. The clamping lifting support 211 is provided with a plurality of mounting holes. The clamping assembly 212 is adjusted in height by being installed on different mounting holes. The clamping assembly 212 includes a clamping frame 2121, a clamping control rod 2122, a clamping rod 2123 and a clamping connecting rod 2124. The clamping frame 212 A crossbeam matched with the clamping rod 2123 is provided on the lower side. The crossbeam and the clamping frame 2121 clamp the mold support 3 together. The clamping rod 2123 and the clamping control rod 2122 are both rotatably mounted on the clamping frame 2121. Both ends of the clamping control rod 2122 are rotatably mounted on the clamping control rod 2122 and the clamping rod 2123 respectively. The clamping rod 2123 squeezes the mold support 3. When the directions of the clamping link 2124 and the clamping control rod 2122 are parallel, clamping is achieved. Because the clamping link 2124 and the clamping control rod 2122 are parallel, it is a dead point position, which ensures reliable clamping.
[0028] Please note that if Figure 4 Please note Figure 4 The state is that the directions of the clamping connecting rod 2124 and the clamping control rod 2122 are parallel. At this time, the mold clamping device 21 is at the dead point of the mechanism and can realize the clamping function. This clamping method has a large clamping force and is labor-saving and quick.
[0029] Specifically, the mold bracket 3 is fitted to the inner mold 5, thereby ensuring the dimensional accuracy of the inner mold 5. The mold bracket 3 is manufactured by pasting paper pieces at the parting line position of the inner mold 5. These paper pieces are distributed along the parting line. Only on one side of these paper pieces, glass fiber cloth is laid on the inner mold 5, and resin is applied on the glass fiber cloth until the glass fiber cloth is soaked. After the resin solidifies, the glass fiber cloth is laid again and the resin is applied again until the glass fiber cloth is soaked, until a first bracket made of resin material with glass fiber cloth as the skeleton is formed on the outside of the inner mold 5, and then glass fiber cloth is laid on the other side of the paper piece to fit the inner mold 5, and resin is applied. Similar to the first bracket, a second bracket is formed. The first bracket and the second bracket can be disassembled along the position of the paper piece. The first paper piece and the second paper piece form the mold bracket 3. The manufacturing method of the above-mentioned mold bracket 3 is a conventional mold bracket manufacturing method, which will not be repeated here.
[0030] Specifically, the inner mold 5 is made of silicone, which is convenient for mold turning. The inner mold 5 is made by first determining the mold opening line on the mold, spraying detergent water on the outside of the mold to facilitate demolding, and then pasting several paper pieces along the mold opening line, and applying silicone on the paper pieces and the outside of the mold. After the silicone is completely dry, apply silicone again, and repeat until a silicone layer of sufficient thickness is formed outside the mold to form the inner mold 5. The inner mold 5 is made in a conventional way of making a silicone mold, which will not be repeated here.
[0031] A method for opening a mold for a resin craft casting mold uses a mold opening device for a resin craft casting mold, comprising the following steps: S1: The mold support 3 wraps the inner mold 5; S2: the mold clamping system 2 clamps the mold support 3, the tracking vibration plate 42 presses the mold support 3, and injects material into the inner mold 5; S3: The mold rotating system 1 rotates the mold support 3; S4: The inertial flywheel 41 and the tracking vibration plate 42 are mutually displaced, and the vibration cone 411 slides along the vibration guide groove 421 and is pressed into the vibration groove 422 one by one, thereby generating vibration, so that the material in the inner mold 5 is evenly distributed; S5: Unlock the mold clamping system 2, remove the mold support 3, open the mold support 3 and take out the inner mold 5.
