Description

Technical Field

[0001] The invention relates to a crystal glass forming process, in particular to a crystal glass thread forming process and a forming die. Background Art

[0002] In order to make the light produced by itself have different emission effects, many lamps now choose to install different crystal glass lamps on and around the light source, and use the facets on the surface of the crystal glass lamps, different shapes of sides, etc., to make the final emitted light have different effects. In this design, it is necessary to perform different shape facet forming work on the surface of the crystal glass; at present, the different shapes of the crystal glass surface are mainly set by forming, but because the crystal glass needs to be melted during the forming process, and the mold used each time can only perform die-casting forming work on one shape of facet, when it is necessary to set multiple shapes of facets on a piece of crystal glass, the other facet can only be produced by a simple way that can be used for carving, and it needs to be completed on one facet at a time, and cannot be processed at the same time, and the overall work efficiency is low. Therefore, there is a problem of low work efficiency in the existing crystal glass forming process. Summary of the invention

[0003] The purpose of the present invention is to provide a crystal glass thread forming process and a forming die. The present invention has the advantage of high working efficiency.

[0004] The technical solution of the present invention is a crystal glass thread forming process, comprising the following steps:

[0005] A. Make the mold. First, make different mold grooves on different mold blocks according to the final shape of the crystal glass to be processed; then grind and polish the mold blocks; finally, assemble all the mold blocks on the shell to form a forming mold;

[0006] B. Soften the crystal glass raw material, put the crystal glass raw material into the glass melting furnace, and heat the crystal glass raw material to 900°C to 1100°C, so that the crystal glass raw material is in a semi-molten state;

[0007] C. Putting the mold into the mold for shaping: first, the forming mold is opened so that an opening for pouring the crystal glass raw material appears on the forming mold; then the semi-molten crystal glass raw material is added into the forming mold; finally, the forming mold is closed to shape the crystal glass raw material; finally, the formed crystal glass is obtained and taken out from the forming mold;

[0008] D. Annealing: placing the formed crystal glass into an annealing furnace for annealing to obtain the final product.

[0009] In the aforementioned crystal glass thread forming process, the mold groove in step A is divided into a thread groove and a water pattern groove; three mold blocks are provided, and the mold groove on one mold block is a thread groove; and the mold grooves on the other two mold blocks are water pattern grooves.

[0010] In the aforementioned crystal glass thread forming process, the mold groove in step A is divided into a thread groove and a water pattern groove; four mold blocks are provided, of which the mold grooves on two mold blocks are thread grooves; and the mold grooves on the other two mold blocks are water pattern grooves.

[0011] According to the aforementioned crystal glass thread forming process, a crystal glass thread forming mold is adopted, including an outer shell, in which two symmetrically distributed side mold blocks and an end mold block are arranged; the end mold block and the two side mold blocks are distributed in a ring shape in the outer shell; each side mold block is provided with a water groove on the side facing the other side mold block; the end mold block is provided with a thread groove on the side facing the side mold block; a push plate is provided on the inner bottom surface of the outer shell, and a push member is connected to the bottom surface of the push plate; the bottom surfaces of the end mold block and the two side mold blocks are connected to the top surface of the push plate.

[0012] In the aforementioned crystal glass thread forming mold, the bottom surfaces of the end mold block and the side mold block are provided with slots at positions corresponding to the positions connected with the push plates; the push member is connected with the end mold block and the two side mold blocks through the slots.

[0013] In the aforementioned crystal glass thread forming mold, the inner side wall of the shell is an inclined surface, and the distance from the bottom end of the inclined surface to the central axis of the shell is smaller than the distance from the top end of the inclined surface to the central axis of the shell.

[0014] In the aforementioned crystal glass thread forming mold, a plurality of guide rails are arranged on the inclined surface; guide grooves cooperating with the guide rails are arranged on the outer side walls of the end mold block and the side mold block; by arranging the guide rails and the guide grooves, the movement of the side mold block and the end mold block can be guided, thereby ensuring the stability of the movement of the side mold block and the end mold block.

[0015] In the aforementioned crystal glass thread forming mold, the outer side walls of the end mold block and the side mold block are inclined surfaces, and the inclination of the inclined surface is the same as the inclination of the inclined surface.

[0016] In the aforementioned crystal glass thread forming mold, two end mold blocks are provided, and the two end mold blocks are symmetrically arranged on both sides of the two side mold blocks.

[0017] Compared with the prior art, the present invention designs a crystal glass thread forming process, by arranging a plurality of mold blocks on the entire forming mold, and mold grooves of different shapes are arranged on the mold blocks at different positions, and then assembling these mold blocks together, so that when the crystal glass raw material in a semi-molten state is subsequently added to the entire forming mold, different shapes, especially threads or water ripples, can be integrally formed on the surface of the crystal glass. Compared with the previous processing method, not only can the work efficiency of the entire crystal glass production be improved, but different mold blocks can also be replaced according to the shape of the crystal glass to be actually produced, and the use flexibility is high; and by melting the crystal glass raw material into a semi-molten state, that is, although the crystal glass raw material has a certain fluidity, it is still in a certain solid state as a whole, so that it is convenient to put the crystal glass raw material into the forming mold, and at the same time, the rate of mold pressure forming is guaranteed, which facilitates the operation and further improves the work efficiency. In addition, the present invention also sets the mold grooves of two molds as water pattern grooves and the mold groove of one mold as a thread groove, so that the two water pattern grooves can form water pattern on the side of the crystal glass raw material. This water temperature pattern can form a focusing effect after the product is installed on the lamp; and the thread groove can form a thread structure at the end of the crystal glass raw material. The thread structure can increase the stability of the product after it is installed on the lamp and the convenience of installation.

[0018] At the same time, a push plate is installed in the shell, a push piece is connected to the bottom surface of the push plate, and all the mold blocks are connected to the push plate, so that when the external thrust pushes the push plate upward through the push piece, the side mold block and the end mold block can be pushed upward by a certain distance, so that the tightening effect of the shell on the top end of the mold block disappears, so that the tightness between the ends of the mold block is reduced, which is convenient for taking out the crystal glass product inside; and when the external pulling force pulls the push piece to move downward, the push plate will drive the side mold block and the end mold block to move downward back into the shell, so that the tightness between the ends of the side mold block and the end mold block is increased, ensuring the die-casting forming effect. Compared with the previous molds for crystal production and processing, it is not only convenient to carry out the demoulding work, but also very convenient to use; and there is no need to worry about the whole demoulding process. The mold will not be damaged, the reuse rate of the mold is improved, and the production cost is reduced; by providing a card slot on the bottom surface of the side mold block and the end mold block, and the end of the pusher is connected between all the card slots, so that the pusher can stably drive the side mold block and the end mold block to move up and down, thereby improving the stability of the structure; by setting the inner side wall of the shell as an inclined surface, and cooperating with the side of the side mold block and the end mold block to also provide an inclined surface, the inclined surface can be used to guide the ends of the side mold block and the end mold block to gather or spread in the process of the side mold block and the end mold block moving up and down, thereby facilitating the blanking and ensuring the casting effect; by providing a guide rail and a guide groove, the movement of the side mold block and the end mold block can be guided, thereby ensuring the stability of the movement of the side mold block and the end mold block. Therefore, the present invention can not only improve the work efficiency, but also has the advantages of high flexibility of use, convenient use, high structural stability, long service life, good casting effect and low production cost.

[0038] According to the aforementioned crystal glass thread forming process, a crystal glass thread forming mold is used to form a crystal glass thread forming mold. Figures 1 to 3As shown, it includes a shell 1, in which two symmetrically distributed side mold blocks 2 and an end mold block 3 are arranged; the end mold block 3 and the two side mold blocks 2 are distributed in a ring shape in the shell 1; each side mold block 2 is provided with a water groove 10 on the side facing the other side mold block 2, and the end mold block 3 is provided on one side of the two side mold blocks 2; the end mold block 3 is provided with a threaded groove 4 on the side facing the side mold block 2; a push plate 5 is provided on the inner bottom surface of the shell 1, and a push member 6 is connected to the bottom surface of the push plate 5; the bottom surfaces of the end mold block 3 and the two side mold blocks 2 are connected to the top surface of the push plate 5.

[0039] The bottom surfaces of the end mold block 3 and the side mold block 2 are provided with card slots 7 at positions corresponding to the connection with the push plate 5; the pushing member 6 is card-connected with the end mold block 3 and the two side mold blocks 2 through the card slots 7; the inner side wall of the shell 1 is an inclined surface, and the distance from the bottom end of the inclined surface to the central axis of the shell 1 is smaller than the distance from the top end of the inclined surface to the central axis of the shell 1; a plurality of guide rails 8 are arranged on the inclined surface; the outer side walls of the end mold block 3 and the side mold block 2 are provided with guide grooves 9 that cooperate with the guide rails 8; the outer side walls of the end mold block 3 and the side mold block 2 are inclined surfaces, and the inclination of the inclined surfaces is the same as the inclination of the inclined surfaces; there are two end mold blocks 3, and the two end mold blocks 3 are symmetrically arranged on both sides of the two side mold blocks 2.

[0040] Working principle: In the process of forming the crystal glass thread, first install the side mold block 2 and the end mold block 3 into the shell 1; then put the crystal glass raw material into the glass melting furnace, so that the crystal glass raw material is heated to between 900℃ and 1100℃ (generally heated to 1000℃). During the whole time, the crystal glass raw material is in a semi-solid state, that is, the inside is still hard, but the surface has a certain fluidity, which is convenient for die-casting; then push the pusher 6 upward through the external thrust, and the pusher 6 will drive the push plate 5 to move upward during the movement, because the pusher The plate 5 is clamped together with the bottom end of the side mold block 2 and the bottom end of the end mold block 3 through the clamping groove 7, so that the side mold block 2 and the end mold block 3 can be pushed upward together during the upward movement of the push plate 5. At this time, the side mold block 2 and the end mold block 3 will move upward along the guide rail 8 and the top surfaces of the side mold block 2 and the end mold block 3 will move away from each other, so that an opening for placing the crystal glass raw material is generated between the top surfaces of the side mold block 2 and the end mold block 3; then the semi-solid crystal glass raw material can be placed between the side mold block 2 and the end mold block 3.

[0041] Then, the push member 6 is pulled downward by an external pulling force. During the downward movement of the push member 6, the push plate 5 is driven to move downward. During the movement of the push plate 5, all the mold blocks 2 can be driven to move into the shell 1, and finally the side mold block 2 and the end mold block 3 are entered into the shell 1. The shell 1 is used to tighten the ends of the side mold block 2 and the end mold block 3, so that the opening diameters of the top ends of the side mold block 2 and the end mold block 3 are reduced to the initial state. During the movement of the side mold block 2 and the end mold block 3 into the shell 1, the semi-solid crystal glass raw material is also driven to enter the shell 1 together. As the side mold block 2 and the end mold block 3 are slowly tightened under the action of the shell 1, the pressure between the side mold block 2 and the end mold block 3 and the crystal glass raw material increases, so that the fluid part on the surface of the crystal glass raw material enters the corresponding water pattern groove 10 and the thread groove 4, so that the water pattern structure can be formed on both sides of the crystal glass raw material and the thread structure can be formed at the end of the crystal raw material, thereby completing the casting molding of the crystal glass raw material.

[0042] After the molding work is completed, the pusher 6 is pushed upward again to push out the crystal glass product that has completed the molding work inside, and then the formed crystal glass product is placed in the annealing furnace for annealing. Finally, faceting, grinding, polishing and water washing can be performed on the surface of the crystal glass according to actual production needs.
