Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a resin dripping ring silicone mold. Background Art

[0002] Rings are finger ornaments that we often wear. In addition to precious metals, jewelry and jade, people also use resin to make rings. Since resin is a polymer compound, when processing rings, resin must be dripped into the mold to solidify and form. The most commonly used resin ring mold is a resin dripping silicone mold. When the existing resin dripping silicone mold is being formed, when the mold cover covers the mold opening, some air will be trapped in the membrane cavity. After the ring is formed, bubbles will remain on the surface of the ring, which seriously affects the beauty of the resin ring. In order to eliminate the bubbles on the surface of the ring, people have added the process of exhausting. However, when exhausting, since it is impossible to see where there is air in the mold, the needle can only be inserted into the top surface of the resin in the mold for exhausting. It is extremely difficult to position the needle at the top surface of the resin in the mold, and if the positioning is inaccurate, the resin dripping will enter the needle tube, making it impossible to exhaust. Summary of the invention

[0003] In view of the problems existing in the above technical field, the utility model proposes a resin dripping silicone mold. When the mold cover seals the mold cavity, the air in the mold cavity is automatically discharged, so that the surface of the molded resin ring is bright and transparent without bubbles.

[0004] A resin drip ring silicone mold, comprising a clamp, a mold, a pressing piece and a ring composite; the clamp, the mold and the pressing piece are all made of soft silicone, the ring composite is a hard ring shell, the inner ring of which is provided with a groove for accommodating dripped resin; a first center hole is provided in the middle of the mold for fixing the mold, a second center hole is provided in the middle of the pressing piece, a clamp is provided at the top of the clamp, the clamp passes through the first center hole and the second center hole in sequence upward, and is clamped on the top surface of the pressing piece for clamping the mold; the mold comprises a mold body, a mold cover, a first center hole, a sprue and a mold cavity, the mold cover is arranged on the top of the mold body for sealing the sprue for dripping resin, the mold comprises a mold body and a mold cover, the mold cover is arranged on the top surface of the mold body; the top surface of the mold cover is a pressing surface, and the bottom surface is a covering surface, the pressing surface is a plane, and the covering surface is set as an inclined surface, the inclined surface is inclined upward from the inside to the outside, and the slope of the inclined surface is 20-30 degrees.

[0005] The mold cavity is arranged in the mold body and is used for molding a resin ring. The first center hole is used for cooperating with a clamp to fix the mold body.

[0006] The clamp comprises a base, a central axis and a clamping head, wherein the central axis is used to pass through a first center hole and a second center hole to fix the mold and the pressing piece on the clamp.

[0007] The diameters of the first center hole and the second center hole are equal and are both smaller than the diameter of the chuck.

[0008] The utility model not only omits the step of exhausting air during drip molding, but also makes the surface of the resin ring bright and transparent without bubbles. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further explained clearly and completely below in conjunction with the accompanying drawings and specific embodiments. The described embodiments are only some embodiments of the utility model. For those skilled in the art, other embodiments obtained without creative work all belong to the protection scope of the utility model.

[0014] like Figure 1 As shown, the utility model is a resin dripping ring silicone mold.

[0015] like Figure 1 , 3 As shown in Figure 4, the utility model includes a clamp 1, a mold 2, a pressing piece 3 and a ring composite 4, wherein the clamp 1, the mold 2 and the pressing piece 3 are all made of soft silicone, and the ring composite 4 is a hard ring shell, whose inner ring is provided with a groove for accommodating dripped resin, a first center hole 23 is provided in the middle of the mold 2 for fixing the mold 2, a second center hole 31 is provided in the middle of the pressing piece 3, and a clamp 13 is provided at the top end of the clamp 1, and the clamp 13 passes through the first center hole 23 and the second center hole 31 in sequence upward, and is clamped on the top surface of the pressing piece 3 for clamping the mold 2.

[0016] like Figure 3As shown, the mold 2 includes a mold body 21, a mold cover 22, a first center hole 23, a sprue 24 and a mold cavity 25. The mold cover 22 is arranged on the top of the mold cavity 25 to seal the sprue 24 for dripping resin. The mold 2 includes a mold body 21 and a mold cover 22. The mold cover 22 is arranged on the top surface of the mold body 21; the top surface of the mold cover 22 is a pressing surface 221, and the bottom surface is a covering surface 222. In order to ensure uniform force, the pressing surface 221 is a plane. In order to gradually cover the sprue 24 from the inside to the outside, the covering surface 222 is set as an inclined surface, which is inclined upward from the inside to the outside, and the slope of the inclined surface is 20-30 degrees; the mold cavity 25 is arranged in the mold body 21 for molding a resin ring; the first center hole 23 is used to cooperate with the clamp 1 to fix the mold body 21.

[0017] like Figure 4 As shown, the clamp 1 includes a base 11 , a central axis 12 and a clamp 13 . The central axis 12 is used to pass through the first center hole 23 and the second center hole 31 to fix the mold 2 and the pressing member 3 on the clamp 1 .

[0018] like Figure 2 and 3 As shown, the first center hole 23 and the second center hole 31 have the same diameter, and are both smaller than the diameter of the mold cover 22 .

[0019] When making a ring, place the fixture 1 on a flat surface, insert the mold 2 on the central axis 12 with the injection port 24 facing upward, place the ring composite 4 into the mold cavity 25, and then drip the resin glue into the mold cavity 25, and then insert the clamping piece 3 from the top of the fixture 1 into the central axis 12. When the clamping piece 3 presses the mold cover 22 downward, the side close to the first center hole 23 first contacts the resin glue. As the clamping piece 3 is continuously pressed downward, the slope of the bottom of the mold cover 22 is gradually pressed down from the inside to the outside to the surface of the resin glue. At the same time, the air on the surface of the resin glue is gradually squeezed from the inside to the outside to the outside of the mold cavity 25, so that no air is retained in the mold cavity.

[0020] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
