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 th...

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 no...

Abstract

The invention discloses a method for making a resin diamond, which comprises the following steps in turn: 1. Prepare a master mold: ① provide a diamond shape; ② prepare a mold according to the diamond shape, and process one end of the mold into the shape of the diamond shape Consistent mold heads; ③ Insert multiple molds into the mold cavity of a lower mold, and the mold cavity is provided with a plurality of slots that are mated with the plugs of the molds; 2. Prepare plastic molds : Install the lower mold and an upper mold on the injection molding machine, and use thermoplastic injection molding to form a plastic mold; 3. Forming of resin diamonds: ① Pour AB glue into the plastic cavity formed by the mold head on the plastic mold, Squeeze; ②Put the plastic mold with AB glue into the oven to dry and cure, the drying temperature is 110°C, and the drying time is 50min; ③Take the cured and formed AB rubber block out of the plastic mold cavity, that is A resin diamond rough is obtained. The method is low in cost for making resin diamonds.

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 is...
