Problems solved by technology

However, the processing method similar to this kind of resin diamond has the following disadvantages: ①The hardness of the silicone mold is low, and it is difficult to ensure that the walls of the resin diamond are smooth when the resin diamond is formed, and the refraction effect on light is not good; ②The AB glue is poured into the silicone mold Finally, the AB glue needs to be scraped flat along the mold mouth. After about 20 times of scraping operations, the surface of the silicone mold with low hardness becomes uneven, and the shape of the corresponding processed diamond blank is incomplete. At this time, the silicone mold It can no longer be used; ③The molds described above are generally bonded to the bottom support. After making a silicone mold, the mold will fall off from the bottom support and need to be fixed again, which is troublesome to operate.

Embodiment 1

[0042] according to figure 1 , figure 2 As shown, the manufacturing method of a kind of resin diamond described in the present embodiment comprises the following steps successively:

[0043] 1. Preparation of master model:

[0044] ①Provide a diamond-shaped piece with a diamond shape, and the axial section of the diamond-shaped piece is an isosceles trapezoid or an isosceles triangle;

[0045] 2. Prepare the mold 4 according to the diamond shape, the mold adopts zircon or quartz glass as a raw material, one end of the mold is processed into a mold head 41 consistent with the shape of the diamond shape, and the other end of the mold is processed into a cylindrical shape stakes 42;

[0046] ③Insert a plurality of said mold types into the mold cavity 21 of a lower mold, and provide a plurality of slots 20 that are mated with the inserts of the molds in the mold cavity; when inserting the molds, coat the insert surface with Insert after the colloid; the mold cavity is general...

Embodiment 2

[0061] like image 3 , Figure 4 As shown, the manufacturing method of a kind of resin diamond described in the present embodiment comprises the following steps successively:

[0062] 1. Preparation of master model:

[0063] ①Provide a diamond-shaped piece with a diamond shape, and the axial section of the diamond-shaped piece is an isosceles trapezoid or an isosceles triangle;

[0064] 2. Prepare the mold type 4 according to the diamond shape, the mold type adopts zircon or quartz glass as a raw material, and one end of the mold type is processed into a mold type head 41 consistent with the shape of the diamond type piece, and the middle part of the mold type is processed into a cylindrical Inserting post 42, the other end of mold type is processed into the cylindrical positioning head 43 that diameter is greater than inserting post diameter;

[0065] ③Insert a plurality of mold types into the mold cavity 21 of a lower mold, and a plurality of sockets 22 are provided in t...

Embodiment 3

[0073] like Figure 5 , Figure 9 As shown, two identical lower molds are used as the master mold to form the plastic mold, so that the processed plastic mold has plastic mold cavities on both sides. The service life is doubled, such a piece of plastic mold can be reused 400-500 times, which is 40 to 50 times that of ordinary silicone molds, and there is no way for silicone molds to process a structure with double-sided mold cavities.

[0074] The height of the positioning head is processed to be lower than the depth of the positioning notch, and the height of the positioning head does not need to be very accurate, and then the thermal conductive glue 5 is filled in the positioning notch to be flush with the outer bottom surface of the lower mold. In this way, the processing accuracy of the mold positioning head can be appropriately reduced, and the cost of materials can be reduced. In addition, the use of heat-conducting glue to fill the remaining space in the positioning n...

Abstract

The invention discloses a preparing method for resin diamonds. The preparing method comprises the following steps in sequence: 1, preparing a female mold, namely (1) providing a diamond mold piece, (2) preparing mold seeds according to the diamond mold piece, and machining one end of each mold seed into a mold seed head with the same shape as that of the diamond mold piece, and (3) inserting a plurality of mold seeds into a mold cavity of a lower mold, wherein a plurality of slots for allowing insertion columns to be inserted in a matched manner are formed in the mold cavity; 2, preparing a plastic mold, namely arranging the lower mold and an upper mold on an injection molding machine, and performing injection molding on thermoplastic plastics to form the plastic mold; and 3, molding the resin diamonds, namely (1) pouring AB glue into plastic mold cavities formed in the plastic mold by the mold seed heads, and leveling the AB glue by scraping, (2) putting the overall plastic mold with the AB glue in a drying oven and drying at the drying temperature being 110 DEG C for 50 minutes for curing, and (3) taking the cured AB glue blocks out of the plastic mold cavities to obtain resin diamond blanks. The method for preparing the resin diamonds is low in cost.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a master mold of a resin diamond plastic molding mould. Background technique [0002] The publication number is CN102173016A, and the Chinese patent titled "Manufacturing Method of Resin Diamond" discloses that a diamond-shaped piece with a diamond shape is fixed on the bottom support as a mold, and then liquid silica gel is poured on the mold, and wait for it After curing, the silicone mold is removed from the mold; then the silicone mold is used as a mold, and the AB glue is introduced into the mold cavity, and the AB glue is cured and taken out to form a vertical diamond blank. However, the processing method similar to this kind of resin diamond has the following disadvantages: ①The hardness of the silicone mold is low, and it is difficult to ensure that the walls of the resin diamond are smooth when the resin diamond is formed, and the refraction effect on light i...
