The pressing process of the existing high-temperature forming device for quartz glass processing is carried out in a fixed mold. When quartz glass plates of different sizes need to be pressed, different molds need to be replaced, or the quartz glass plates need to be cut after pressing to obtain quartz glass plates of the required size. Both the mold replacement and the glass plate cutting operations are relatively troublesome, resulting in low processing efficiency. In addition, the cutting operation also generates a large amount of scraps, resulting in material waste, and poor practicality. Summary of the Invention

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0006] Preferably, the multiple top blocks are evenly and tightly arranged into multiple columns, each of the top blocks is provided with a through hole, and multiple fixing blocks are provided at both ends of the support frame, and the multiple fixing blocks extend one by one into the through holes on the multiple top blocks located at both ends of each column.

[0007] Preferably, each of the top blocks is provided with a connecting assembly for connecting with an adjacent top block, and the connecting assembly includes an L-shaped block with one end slidingly connected to the through hole, and the end of the L-shaped block can be slidably extended into the through hole of the adjacent top block.

[0008] Preferably, the bottom of the L-shaped block is slidably connected to a first slider, a spring is fixedly connected between the top of the first slider and the L-shaped block, a second slider is slidably provided in the support frame, the bottom of the first slider and the top of the second slider are both fixed with triangular blocks, and the two sets of inclined surfaces of the two triangular blocks slide together respectively.

[0009] Preferably, a double-headed screw is rotatably connected below each column of the top blocks in the support frame, two second sliders are provided below each column of the top blocks, and the two second sliders are symmetrically screwed together and connected to the two ends of the corresponding double-headed screw.

[0010] Preferably, a plurality of limiting rods are fixed in the support frame, and grooves for slidingly cooperating with the limiting rods are formed on both sides of the top block.

[0011] Preferably, a closed space is formed between the support frame and the plurality of top blocks, an air intake pipe and an exhaust pipe are fixed through one side of the support frame, and one end of the air intake pipe and the exhaust pipe extend into the closed space.

[0012] Preferably, valves are rotatably provided on both the air inlet pipe and the exhaust pipe.

[0013] Preferably, a screw rod is rotatably connected in the box body, a slide seat is screwed on the screw rod, and the bottom of the support frame is fixedly connected to the slide seat.

[0014] Preferably, a motor is fixedly mounted on one side of the box body, and an output end of the motor is fixedly connected to one end of the screw rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention provides a mold assembly, wherein a plurality of top blocks slide within a support frame so that a height difference is formed between the top block located in the middle and the top blocks located at the edge. The top block located in the middle forms a sink groove for pressing a quartz glass plate. By combining different numbers of top blocks, mold sink grooves of different sizes can be formed, which facilitates the pressing of quartz glass of different sizes. The complicated operation of replacing various molds is not required, thereby improving processing efficiency.

[0017] (2) As mentioned above, the fixing blocks on the support frame cooperate with the through holes on the top blocks at both ends of each column to fix the top blocks in the vertical direction, and then the multiple top blocks can be connected in sequence from both ends to the middle through the L-shaped card blocks in the connection assembly. By connecting different numbers of top blocks, the middle top block can form sinking grooves of different widths after sinking. In addition, the length of the sinking groove can be controlled by adjusting the top blocks of each column separately, thereby realizing the formation of sinking grooves of different sizes by the mold assembly.

[0018] (3) The present invention is provided with a double-headed screw. By rotating the double-headed screw, the two second sliders in the same row slide toward the middle at the same time. The second slider first pushes the L-shaped block to slide through the first slider, so that the L-shaped block extends into the through hole of the adjacent top block, thereby fixing the two top blocks in the vertical direction until one side of the L-shaped block contacts the inner wall of the top block. Then the second slider continues to slide. The second slider slides with the two triangular blocks on the first slider to make the first slider compress the spring, so that the second slider moves to the other side of the first slider. Then the second slider can continue to move to push the first slider in the next top block, repeat the above steps, and so on. The top blocks of a row can be connected in sequence from both ends to the middle. The moving distance of the second slider is controlled according to the width of the quartz glass plate to be pressed, thereby controlling the number of connections of the top blocks and adjusting the width of the mold sink. The above operation only requires the staff to rotate the double-headed screw, which is simple to operate and can improve the adjustment efficiency of the mold assembly, thereby improving the processing efficiency.

[0019] (4) The present invention is provided with an air inlet pipe and an exhaust pipe. When the exhaust pipe is closed and air is inflated from the air inlet pipe, the air pressure in the enclosed space formed between the support frame and the plurality of top blocks is gradually increased, so that the top blocks move upward, which can be used for demolding the quartz glass and resetting the top blocks. When the air inlet pipe is closed and air is exhausted from the exhaust pipe, the air pressure in the enclosed space is reduced, so that the unconnected top blocks move downward to form a mold sink, thereby improving the adjustment efficiency. When both the air inlet pipe and the exhaust pipe are opened, air is filled in for circulation, which can accelerate the cooling and molding efficiency of the quartz glass through heat conduction and cooling of the top blocks.

[0020] (5) The present invention is provided with a screw rod, which is driven by a motor to rotate so that the screw-connected slide can drive the support frame to move to the outside of the box body, thereby driving the formed quartz glass and the mold sink to move to the outside of the box body, avoiding the need for workers to reach into the box body when unloading and loading materials to avoid burns, thereby improving safety.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-9 As shown, the present invention provides the following technical solutions:

[0033] A high-temperature forming device for processing quartz glass includes a box body 1 and a box door 10 rotatably connected to one side of the box body 1. A plurality of heating plates 11 are provided on the inner wall of the box body 1. A mold assembly is provided in the box body 1. A hydraulic push rod 12 is fixedly installed on the top of the box body 1. A pressure plate 2 is fixedly installed at the telescopic end of the hydraulic push rod 12. The pressure plate 2 is located above the mold assembly. The mold assembly includes a support frame 5 and a plurality of top blocks 4 slidably connected to the support frame 5.

[0034] Based on the above disclosed structure, when performing high temperature forming operation of quartz glass:

[0035] The quartz glass is pressed and molded by high-temperature pressing. The hydraulic push rod 12 is then started to retract the telescopic end, so that the pressing plate 2 is moved away from the support frame 5. The quartz glass to be molded can be removed from the mold sink after cooling and hardening.

[0036] As mentioned above, regarding the adjustment of the top block 4, it is preferably provided with the following structure:

[0037] The plurality of top blocks 4 are evenly and closely arranged in a plurality of rows, each of which is provided with a through hole 19, and a plurality of fixing blocks 20 are provided at both ends of the support frame 5, and the plurality of fixing blocks 20 extend into the through holes 19 on the plurality of top blocks 4 at both ends of each row in a one-to-one correspondence;

[0038] Each top block 4 is provided with a connecting assembly for connecting with the adjacent top block 4, and the connecting assembly includes an L-shaped block 3 with one end slidably connected to the through hole 19, and the end of the L-shaped block 3 can slide into the through hole 19 of the adjacent top block 4;

[0039] A first slider 16 is slidably connected to the bottom of the L-shaped block 3, and a spring 18 is fixedly connected between the top of the first slider 16 and the L-shaped block 3. A second slider 17 is slidably provided in the support frame 5. A triangular block is fixed to the bottom of the first slider 16 and the top of the second slider 17, and the two sets of inclined surfaces of the two triangular blocks are slidably matched.

[0040] A double-headed screw 7 is rotatably connected below each column of top blocks 4 in the support frame 5 . Two second sliders 17 are provided below each column of top blocks 4 , and the two second sliders 17 are symmetrically screwed together and connected to the two ends of the corresponding double-headed screw 7 .

[0041] The two second sliders 17 are respectively pushed into the through holes 19 of the two adjacent top blocks 4, so that the top blocks 4 and the support frame 5 are fixed in a row. The double-headed screw 7 is rotated to make the two second sliders 17 continue to move toward the middle. At this time, the inclined surface of one side of the triangular block at the top of the second slider 17 slides with the inclined surface of one side of the triangular block at the bottom of the first slider 16, so that the first slider 16 moves upward and compresses the spring 18 until the first slider 16 is completely retracted above the second slider 17. The second slider 17 continues to move to the inside of the first slider 16. Then the double-headed screw 7 can be continued to be rotated to make the two second sliders 17 continue to move toward the middle and approach the first slider 16 in the adjacent top block 4. At this time, the above steps can be repeated to complete the connection between the adjacent top block 4 and the next top block 4. By analogy, each column of top blocks 4 can be connected from both ends to the middle in sequence, and the upper surfaces of multiple top blocks 4 overlap. The distance the second slider 17 moves toward the middle is controlled according to the width of the quartz glass plate to be pressed, thereby controlling the number of connected top blocks 4. Then, the top blocks 4 that are not connected in the middle are slid downward to the bottom and abut against the bottom of the support frame 5, thereby controlling the width of the mold sink.

[0042] Then, each column of top blocks 4 is adjusted separately through the above operation, so that a mold sink is formed between multiple columns of top blocks 4. The length of the mold sink is controlled by the number of columns that make up the mold sink, so that the mold assembly can be used to press quartz glass of different sizes.

[0043] In addition, when the connection needs to be disconnected for assembling different mold sinks after the processing is completed, the second slider 17 is located on the inner side of the first slider 16, and the first slider 16 is reset downward under the elastic force of the spring 18. The two second sliders 17 are moved to both ends by rotating the double-headed screw 7 in the opposite direction. The other side inclined surface of the triangular block at the top of the second slider 17 contacts the other side inclined surface of the triangular block at the bottom of the first slider 16 in the top block 4, so that the second slider 17 pushes the L-shaped block 3 to move to both ends through the first slider 16, so that the end of the L-shaped block 3 slides out of the through hole 19 on the adjacent top block 4 until the other side of the L-shaped block 3 contacts the inner wall of the other side of the top block 4. , so as to achieve the disconnection between the two adjacent top blocks 4, and at this time continue to move the second slider 17 to both ends, and the other side of the inclined surface of the triangular block at the top of the second slider 17 slides with the other side of the inclined surface of the triangular block at the bottom of the first slider 16, so that the first slider 16 compresses the spring 18 again, so that the second slider 17 moves to the outside of the first slider 16, and then continues to rotate the double-headed screw 7 to move the second slider 17 to one side of the support frame 5. At the same time, during the movement, the above operation is repeated in sequence for the first slider 16 that passes through, so as to achieve the disconnection of multiple blocks 4 from both ends of the middle part in sequence, so that the mold assembly can be reassembled into mold sinks of different sizes next time.

[0044] In addition, in order to realize the automatic sliding of the top block 4 in the support frame 5, the following structure is preferably provided:

[0045] A plurality of limiting rods 14 are fixed in the support frame 5, and grooves 13 are provided on both sides of the top block 4 for sliding engagement with the limiting rods 14;

[0046] A closed space is formed between the support frame 5 and the plurality of top blocks 4. An air intake pipe 6 and an exhaust pipe 9 are fixed through one side of the support frame 5, and one end of the air intake pipe 6 and the exhaust pipe 9 extends into the closed space.

[0047] Valves are rotatably provided on the air inlet pipe 6 and the exhaust pipe 9.

[0048] As can be seen from the above, the air inlet pipe 6 and the exhaust pipe 9 are preferably connected to an external blower and an exhaust fan respectively (not shown in the figure). Initially, the upper surfaces of the multiple top blocks 4 need to coincide with the upper surface of the support frame 5 to facilitate the connection between adjacent top blocks 4. At this time, the valve on the air inlet pipe 6 is opened, the valve on the exhaust pipe 9 is closed, and the blower is started to inflate the closed space formed between the support frame 5 and the multiple top blocks 4, so that the air pressure in the closed space gradually increases, thereby pushing the multiple top blocks 4 upward. At the same time, the grooves 13 on both sides of the top block 4 slide on the outside of the limiting rod 14 until the lowest point of the groove 13 contacts the bottom of the limiting rod 14, so that the limiting rod 14 limits the multiple top blocks 4. At this time, the upper surfaces of the multiple top blocks 4 coincide with the upper surface of the support frame 5, that is, the top blocks 4 are reset to facilitate the connection between adjacent top blocks 4. In addition, this process can also be used to push the quartz glass upward after the quartz glass is press-formed, thereby completing the automatic demoulding of the quartz glass and improving efficiency.

[0049] After the adjustment and connection of the mold assembly is completed, when the unconnected top block 4 needs to be moved down to contact the bottom of the support frame 5, the valve on the air inlet pipe 6 is closed, the valve on the exhaust pipe 9 is opened, and the exhaust fan is started to extract the air in the enclosed space, so that the air pressure in the enclosed space gradually decreases, thereby allowing the external air pressure to push the unconnected top block 4 to slide downward until the bottom of the top block 4 contacts the bottom of the support frame 5, thereby realizing the automatic downward movement of the top block 4 and improving the adjustment efficiency of the mold assembly;

[0050] In addition, after the quartz glass is pressed, the valves on the air inlet pipe 6 and the exhaust pipe 9 can be opened, and the flow between the gas in the closed space and the outside air can be accelerated by a blower or exhaust fan. In this way, heat can be conducted through the top block 4 to cool the quartz glass, accelerate the cooling and hardening of the quartz glass, and improve the processing efficiency.

[0051] Furthermore, a screw rod 15 is rotatably connected to the box body 1, and a slide 8 is screwed onto the screw rod 15. The bottom of the support frame 5 is fixedly connected to the slide 8. A motor 21 is fixedly mounted on one side of the box body 1, and the output end of the motor 21 is fixedly connected to one end of the screw rod 15. Based on this, after high-temperature pressing and molding, the box door 10 is opened, and the motor 21 drives the screw rod 15 to rotate, causing the screwed slide 8 to slide inside the box body 1, thereby causing the slide 8 to drive the support frame 5 to move to the outside of the box body 1, thereby causing the multiple top blocks 4 and the quartz glass to move to the outside of the box body 1. At this time, the staff can complete the unloading of the quartz glass and the loading of the quartz glass raw materials outside the box body 1, avoiding the need for the staff to reach into the box body 1 to perform operations, thereby preventing the high temperature inside the box body 1 from causing burns to the staff, and improving safety.
