Description

Technical Field

[0001] The invention belongs to the technical field of 3D hard gold processing, and in particular relates to an injection mold assembly for 3D hard gold processing. Background Art

[0002] 3D hard gold has the same purity as ordinary pure gold, but 3D hard gold uses different processes in different positions, some are polished, some are frosted, creating a contrast between light and dark. The color layering is clearer, the three-dimensional sense is stronger, and the texture is also differentiated. When you touch it, some places are smooth and delicate, and some places have a slight frosted feeling, which feels rich. 3D hard gold jewelry is a new type of product that breaks the traditional manufacturing process. The emergence of 3D hard gold has completed a gorgeous "turnaround" for gold. 3D hard gold effectively solves the problem of gold's lack of toughness and three-dimensional sense. It is not only of high purity, but also has the toughness of 18K gold, making gold more plastic, thus achieving a high level of plastic effect with vivid shapes. 3D hard gold combines carving, hollowing, twisting, burning green and other processes to create different three-dimensional, vivid and lifelike shapes. The interior of 3D hard gold jewelry is a hollow structure, and the molds used to create 3D hard gold jewelry are basically disposable molds, which are convenient for washing out the material that makes the hollow interior of the 3D hard gold jewelry. Since 3D hard gold cannot be restored once it is dented and needs to be reprocessed through the mold, the 3D hard gold jewelry molds are subject to large wear and tear and are costly.

[0028] The connecting block 202 on the upper mold 2 is aligned with the connecting groove 103 on the lower mold 1 and inserted so that the upper mold 2 is installed in the square groove 101 on the lower mold 1. The sealing block 203 is connected to the sealing groove 104 to block the top of the injection groove 105. The cylindrical block 201 on the upper mold 2 enters the injection groove 105 to form a hollow. After the lower mold 1, the upper mold 2 and the sealing plate 401 are connected, the molten gold is poured into the injection port 701. The gold enters the mold groove 105 through the injection port 701. 2, and then enters another injection molding groove 105 through the injection molding groove 105. After the injection molding is completed and cooled, the lower mold 1, the upper mold 2 and the sealing plate 401 are separated. At this time, the finished products in the two mold grooves 102 are connected by the gold rods in the injection molding groove 105, which is convenient for taking out the finished products in the two mold grooves 102. After the finished products are taken out, they are separated from the gold rods, and the two finished products are polished and heated to form 3D hard gold jewelry, thereby avoiding the situation that the mold for making 3D hard gold jewelry is one-time, which makes the cost higher.

[0029] A movable groove 3 is symmetrically provided on the top of the upper mold 2, and an inner cross-head threaded rod 301 is installed on the inner wall of the movable groove 3. A pressure block 302 is rotatably installed at one end of the inner cross-head threaded rod 301. The outer surface of the inner cross-head threaded rod 301 is threadedly connected to the upper mold 2. Rotating the inner cross-head threaded rod 301 allows the inner cross head of the inner cross-head threaded rod 301 to move in the movable groove 3.

[0030] The inner cross head threaded rod 301 is rotated so that the inner cross head of the inner cross head threaded rod 301 can move downward in the movable groove 3, and the pressing block 302 at the bottom of the inner cross head threaded rod 301 is moved out of the upper mold 2, and the upper mold 2 is pushed out of the square groove 101, so as to prevent the upper mold 2 from being connected in the square groove 101 and unable to be moved out.

[0032] Align the four hook blocks 407 on the sealing plate 401 with the L-shaped groove 4 on the lower mold 1 and insert them. Since one side of the hook block 407 is a bevel, when the hook block 407 contacts the opening of the L-shaped groove 4, the hook block 407 moves and then automatically inserts into the L-shaped groove 4 and quickly resets, so that the sealing plate 401 is installed on the lower mold 1. Move the four sliding blocks 406 so that the hook block 407 moves to the other side of the L-shaped groove 4, and separate the sealing plate 401 from the lower mold 1 through the sliding blocks 406, so that the sealing plate 401 and the lower mold 1 can be quickly connected and separated.

When connecting the sealing plate 401, the plug-in block No. 1 aligns with the slot No. 1 603 on the lower mold 1 and is inserted, and the plug-in block No. 2 aligns with the slot No. 2 604 on the lower mold 1 and is inserted, so that the connection between the lower mold 1 and the sealing plate 401 is more stable, a cooling groove 7 is opened on the inner wall of the lower mold 1, and one side of the cooling groove 7 is wavy. When the cooling water passes through the cooling groove 7, its contact area is increased, which accelerates the cooling of the internal molten metal, and an injection port 701 is opened on the outer wall of the lower mold 1.

[0035] Working principle: A technician in this field aligns the connecting block 202 on the upper mold 2 with the connecting groove 103 on the lower mold 1 and inserts it so that the upper mold 2 is installed in the square groove 101 on the lower mold 1. The sealing block 203 is connected to the sealing groove 104 to block the top of the injection groove 105, and the cylindrical block 201 on the upper mold 2 enters the injection groove 105 to form a hollow. After the lower mold 1, the upper mold 2 and the sealing plate 401 are connected, the molten gold is poured into the injection port 701, and the gold enters the mold groove 102 through the injection port 701, and then enters another injection groove 105 through the injection groove 105. After the injection is completed and cooled, the lower mold 1, the upper mold 2 and the sealing plate 401 are separated. At this time, the finished products in the two mold grooves 102 are connected by the gold rod in the injection groove 105, which is convenient for taking out the finished products in the two mold grooves 102. After the finished products are taken out, they are separated from the gold rod, and the two finished products are polished and heated to form a 3D hard gold jewelry, avoiding the production of The mold of 3D hard gold jewelry is disposable, which makes the cost relatively high. The inner cross head threaded rod 301 is rotated so that the inner cross head of the inner cross head threaded rod 301 can move downward in the movable groove 3, and the pressure block 302 at the bottom of the inner cross head threaded rod 301 is moved out of the upper mold 2, and the upper mold 2 is ejected from the square groove 101 to prevent the upper mold 2 from being connected in the square groove 101 and unable to be moved out. The four hook blocks 407 on the sealing plate 401 are aligned with the L-shaped groove 4 on the lower mold 1 and inserted. Since one side of the hook block 407 is a bevel, when the hook block 407 contacts the opening of the L-shaped groove 4, the hook block 407 moves and then automatically inserts into the L-shaped groove 4 and quickly resets, so that the sealing plate 401 is installed on the lower mold 1, and the four sliding blocks 406 are moved so that the hook block 407 moves to the other side of the L-shaped groove 4, and the sealing plate 401 is separated from the lower mold 1 by the sliding block 406, so that the sealing plate 401 and the lower mold 1 can be quickly connected and separated.
