Description

Technical Field

[0001] The present invention relates to the technical field of plastic molding, and particularly to an opening device and method for a resin handicraft casting mold. Background Art

[0002] Resin handicrafts are mainly made of resin and are formed by casting in a mold to make various beautifully shaped and vivid figures, animals, birds, landscapes, etc., and various simulation effects can be achieved. Such as: resin handicrafts imitating copper, gold, silver, crystal, agate, marble, white marble, wood, etc.

[0003] When resin handicrafts are formed, liquid silicone is first injected into the mold, and then the liquid silicone solidifies into a resin handicraft. There are still problems in ensuring the uniform distribution of liquid silicone in the existing mold, resulting in uneven thicknesses at various parts of the finished silicone mold. It is necessary to design a mold that can make the material evenly distributed. Summary of the Invention

[0004] To overcome the technical defects existing in the prior art, the present invention provides an opening device and method for a resin handicraft casting mold, which facilitates the uniform distribution of the still-uncompletely-cured liquid silicone before curing.

[0005] The technical solution adopted by the present invention is as follows:

[0006] An opening device for a resin handicraft casting mold includes a mold rotation system, a mold clamping system, a mold support, an inertial vibration system, and an inner mold. The mold clamping system is installed on the mold rotation system, the mold clamping system clamps the mold support, the mold support is used to hold the inner mold, the inertial vibration system includes an inertial flywheel and a tracking vibration disk. The inertial flywheel is rotatably installed on the mold rotation system, a plurality of vibration cones are provided on the inertial flywheel, a vibration guiding groove for each vibration cone to slide is provided on the lower side of the tracking vibration disk, and a plurality of vibration grooves are provided in each vibration guiding groove, and each vibration groove is adapted to the corresponding vibration cone.

[0007] Preferably, the tracking vibration disk has elastic silicone columns, and each vibration cone is installed on the elastic silicone column.

[0008] Preferably, the top of the tracking vibration disk is covered with rubber.

[0009] Preferably, the mold rotation system includes a rotary arm, a flipping motor, and a flipping frame. The rotary arm is externally connected to a rotary motor, the rotary arm is installed at the output end of the rotary motor, the flipping motor is installed at the end of the rotary arm, the flipping frame is installed at the output end of the flipping motor, and the mold clamping system and the inertial vibration system are both installed on the flipping frame.

[0010] Preferably, the mold clamping system includes a number of mold clamping devices. Each mold clamping device includes a clamping lifting bracket and a clamping assembly. The clamping assembly is installed on the clamping lifting bracket. The clamping assembly includes a clamping frame, a clamping control rod, a clamping rod, and a clamping connecting rod. The clamping rod and the clamping control rod are rotatably installed on the clamping frame. The two ends of the clamping control rod are respectively rotatably installed on the clamping control rod and the clamping rod. The clamping rod presses against the mold bracket, and clamping is achieved when the directions of the clamping connecting rod and the clamping control rod are parallel.

[0011] Preferably, the mold bracket fits against the inner mold.

[0012] Preferably, the inner mold is made of silicone material.

[0013] The mold opening method for a resin handicraft casting mold uses a resin handicraft casting mold opening device, and includes the following steps:

[0014] S1: The mold bracket wraps the inner mold;

[0015] S2: The mold clamping system clamps the mold bracket, the tracking vibrating disk presses against the mold bracket, and injects material into the inner mold;

[0016] S3: The mold rotating system rotates the mold bracket;

[0017] S4: The inertial flywheel and the tracking vibrating disk move relative to each other. The vibration cone slides along the vibration guide groove and is successively pressed into the vibration groove, thereby generating vibration, so that the material in the inner mold is evenly distributed;

[0018] S5: Release the mold clamping system, remove the mold bracket, and open the mold bracket to take out the inner mold.

[0019] The beneficial effects of the present invention are:

[0020] The mold clamping system is installed on the mold rotating system. The mold clamping system is used to clamp the mold bracket, and the mold bracket is used to clamp the inner mold. Since the inner mold is made of silicone and has a soft material, a rigid mold bracket needs to be set for support. The inertial vibration system includes an inertial flywheel and a tracking vibrating disk. The inertial flywheel is rotatably installed on the mold rotating system. A number of vibration cones are provided on the inertial flywheel. When the mold rotating system rotates, the inertial flywheel will rotate relative to the mold rotating system. A vibration guide groove for each vibration cone to slide is provided on the lower side of the tracking vibrating disk. A number of vibration grooves are provided in each vibration guide groove, and each vibration groove is adapted to the corresponding vibration cone. Since the mold rotating system clamps the mold bracket, when the inertial flywheel rotates relative to the mold rotating system, the inertial flywheel drives the vibration cone to move relative to the vibration groove, thereby generating vibration. In this way, the liquid material in the inner mold is vibrated while rotating, which is convenient for the not yet fully cured liquid silicone to be evenly distributed before curing.

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] Such as Figure 1 — Figure 6As shown in the figure, this embodiment provides a mold opening device for resin handicraft casting, including a mold rotation system 1, a mold clamping system 2, a mold support 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 support 3, and the mold support 3 is used to hold the inner mold 5. Since the inner mold 5 is made of silicone and has a soft material, a rigid mold support 3 needs to be set up for support. The inertial vibration system 4 includes an inertial flywheel 41 and a tracking vibration disk 42. The inertial flywheel 41 is rotatably installed on the mold rotation system 1 through bearings. A number of vibration cones 411 are provided on the inertial flywheel 41. When the mold rotation system 1 rotates, the inertial flywheel 41 will rotate relative to the mold rotation system 1 under its own inertia. A vibration guiding groove 421 for each vibration cone 411 to slide is provided on the lower side of the tracking vibration disk 42. A number of vibration grooves 422 are provided in each vibration guiding groove 421, and each vibration groove 422 is adapted to the corresponding vibration cone 411. Since the mold rotation system 1 clamps the mold support 3, when the inertial flywheel 41 rotates relative to the mold rotation system 1, the inertial flywheel 41 drives the vibration cones 411 to stagger relative to the vibration grooves 422, thereby generating vibrations. This enables the liquid material in the inner mold 5 to be vibrated while rotating, facilitating the uniform distribution of the still-uncured liquid silicone before curing.

[0035] The working principle of the inertial flywheel 41 and the tracking vibration disk 42 is that the inertial flywheel 41 pushes the tracking vibration disk 42 to the lower side of the mold support 3. In this way, the mold support 3 is not only clamped by each mold clamping system 2, but also pushed by the tracking vibration disk 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 its own inertia, and each vibration cone 411 on the inertial flywheel 41 enters and leaves the vibration groove 422 in turn, causing the tracking vibration disk 42 and the mold support 3 in contact with the tracking vibration disk 42 to vibrate, strengthening the fluidity of the uncured silicone and facilitating the uniform distribution of the uncured silicone in the inner mold 5.

[0036] It should be noted that during the process where each vibration cone 411 enters and leaves the vibration groove 422 in turn, causing the tracking vibration disk 42 and the mold support 3 in contact with the tracking vibration disk 42 to vibrate, if no measures are taken, the tracking vibration disk 42 may cause deformation of the mold support 3, affecting the size of the final product. To solve this problem, a buffer mechanism described below must be set up to avoid possible deformation of the mold support 3.

[0037] Therefore, the tracking vibrating disk 42 has elastic silicone columns 412, and each vibrating 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 vibrating action of the vibrating cone 411 to avoid interference, or to avoid the vibrating groove 422 from jamming the inertial flywheel 41, and at the same time avoid deformation of the mold support 3.

[0038] Specifically, rubber is laid on the top of the tracking vibrating disk 42 to prevent relative sliding between the tracking vibrating disk 42 and the mold support 3 and ensure reliable vibration.

[0039] Specifically, the mold rotating system 1 includes a rotary support arm 11, a flipping motor 12 and a flipping frame 13. The rotary support arm 11 is externally connected to a rotary motor, and the rotary support arm 11 is installed at the output end of the rotary motor. The rotary motor (not shown in the figure) drives the rotary support arm 11 to rotate. The flipping motor 12 is installed at the end of the rotary support arm 11, and the flipping frame 13 is installed at the output end of the flipping motor 12. The flipping motor 12 drives the flipping frame 13 to flip. The mold clamping system 2 and the inertial vibration system 4 are both installed on the flipping frame 13, and the flipping frame 13 is used to clamp the mold support 3.

[0040] Specifically, the mold clamping system 2 includes several mold clamping devices 21. At least three mold clamping devices 21 are required to ensure the stable clamping of the mold support 3. Each mold clamping device 21 includes a clamping lifting bracket 211 and a clamping assembly 212. The clamping assembly 212 is installed on the clamping lifting bracket 211. A number of mounting holes are provided on the clamping lifting bracket 211, and the height of the clamping assembly 212 is adjusted by being installed in 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. A cross beam adapted to the clamping rod 2123 is provided on the lower side of the clamping frame 2121, and the cross beam and the clamping frame 2121 jointly clamp the mold support 3. The clamping rod 2123 and the clamping control rod 2122 are both rotatably installed on the clamping frame 2121. The two ends of the clamping control rod 2122 are respectively rotatably installed on the clamping control rod 2122 and the clamping rod 2123. The clamping rod 2123 presses the mold support 3, and clamping is achieved when the directions of the clamping connecting rod 2124 and the clamping control rod 2122 are parallel. Because the directions of the clamping connecting rod 2124 and the clamping control rod 2122 are parallel at the dead point position, reliable clamping is ensured.

[0041] Please note that as Figure 4 shown, 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 mechanism dead point and can achieve the clamping function. This clamping method has a large clamping force and is labor-saving and rapid in clamping.

[0042] Specifically, the mold support 3 fits against the inner mold 5, thereby ensuring the dimensional accuracy of the inner mold 5. The mold support 3 is fabricated by pasting pieces of paper along the mold closing line of the inner mold 5. These pieces of paper are distributed along the mold closing line. Only outside one side of these pieces of paper, a fiberglass cloth is laid against the inner mold 5, and resin is applied to the fiberglass cloth until the fiberglass cloth is saturated. After the resin solidifies, the fiberglass cloth is laid again and resin is applied again until the fiberglass cloth is saturated, until a first support made of resin material with a fiberglass cloth as the skeleton is formed outside the inner mold 5. Subsequently, a fiberglass cloth is laid against the inner mold 5 outside the other side of the pieces of paper, and resin is applied, similar to the method for making the first support, to form a second support. The first support and the second support can be disassembled along the position of the pieces of paper. The first piece of paper and the second piece of paper form the mold support 3. The above method for making the mold support 3 is the conventional method for making a mold support, which will not be elaborated here.

[0043] Specifically, the inner mold 5 is made of silicone material, which is convenient for mold flipping. The inner mold 5 is fabricated by first determining the mold opening line on the model, and spraying dishwashing detergent water outside the model to facilitate demolding. Then, several pieces of paper are pasted along the position of the mold opening line, and silicone is applied outside the pieces of paper and the model. After the silicone dries, silicone is applied again, repeating until a silicone layer of sufficient thickness is formed outside the model, thereby forming the inner mold 5. The method for making the inner mold 5 is the conventional method for making a silicone mold, which will not be elaborated here.

[0044] The mold opening method for a resin handicraft casting mold uses a resin handicraft casting mold opening device, including the following steps:

[0045] S1: The mold support 3 wraps the inner mold 5;

[0046] S2: The mold clamping system 2 clamps the mold support 3, the tracking vibrating disk 42 presses on the mold support 3, and the inner mold 5 is filled with material;

[0047] S3: The mold rotating system 1 rotates the mold support 3;

[0048] S4: The inertial flywheel 41 and the tracking vibrating disk 42 move relative to each other, the vibration cone 411 slides along the vibration guide groove 421 and is successively pressed into the vibration groove 422, thereby generating vibration, making the material in the inner mold 5 evenly distributed;

[0049] S5: Release the mold clamping system 2, remove the mold support 3, and open the mold support 3 to take out the inner mold 5.
