Preferably, a motor is fixedly mounted on one side of the chassis, and an output end of the motor is fixedly connected to one end of a lead screw.

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

(1) The present invention provides a mold assembly, and a plurality of top blocks slide in a support frame so that there is a height difference between the top block located in the middle and the top blocks located at the edge. The sink groove formed by the top block located in the middle is used to press the quartz glass plate. Different sizes of mold sink grooves can be formed by combining different numbers of top blocks, which is convenient for pressing quartz glass of different sizes. There is no need to perform complicated operations of replacing various molds, thereby improving processing efficiency.

(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 clamping blocks in the connecting 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, so that the mold assembly can form sinking grooves of different sizes.

(3) The present invention is provided with a double-headed screw rod, and by rotating the double-headed screw rod, 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, and then the second slider continues to slide. The second slider and the two triangular blocks on the first slider slide and cooperate with each other to compress the spring of the first slider, so that the second slider moves to the other side of the first slider, and then the second slider can continue to move to push the first slider in the next top block, and the above steps are repeated. By analogy, a row of top blocks 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 top blocks connected and adjusting the width of the mold sink. The above operation only requires the staff to rotate the double-headed screw rod, which is simple to operate and can improve the adjustment efficiency of the mold assembly, thereby improving the processing efficiency.

(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 closed space formed between the support frame and the plurality of top blocks can be gradually increased, so that the top blocks move upward, which can be used for demolding and resetting the quartz glass. When the air inlet pipe is closed and air is exhausted from the exhaust pipe, the air pressure in the closed 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.

(5) The present invention is provided with a screw rod, which is driven by a motor to rotate so that the screw-connected slide seat 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

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

Please refer to Figures 1 to 9, the present invention provides the following technical solutions:

A high-temperature forming device for processing quartz glass comprises 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 arranged on the inner wall of the box body 1, a mold assembly is arranged in the box body 1, a hydraulic push rod 12 is fixedly installed on the top of the box body 1, a pressing plate 2 is fixedly installed on the telescopic end of the hydraulic push rod 12, and the pressing plate 2 is located above the mold assembly, and the mold assembly comprises a support frame 5 and a plurality of top blocks 4 slidably connected to the support frame 5.

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

First, the mold assembly is adjusted according to the size of the quartz glass to be pressed, that is, a plurality of top blocks 4 are slid in the support frame 5 respectively, so that the upper surface of the top block 4 at the edge coincides with the upper surface of the support frame 5, and the top block 4 in the middle slides downward and contacts the bottom of the support frame 5, so that the top block 4 at the edge forms the edge frame of the mold, and the top of the top block 4 in the middle forms a mold sink. The material for producing quartz glass is added into the mold sink, and the box door 10 is closed. Then, the heating plate 11 is started to heat and melt the material, and then the hydraulic push rod 12 is started to push out the telescopic end, thereby pushing the pressing plate 2 close to the upper surface of the support frame 5 until the pressing plate is completely pressed against the upper surface of the top block 4 at the edge. At this time, the molten material is pressed tightly in the mold sink, so that the quartz glass is pressed and formed at high temperature. Then, the hydraulic push rod 12 is started to retract the telescopic end, so that the pressing plate 2 is away from the support frame 5. The quartz glass to be formed can be taken out from the mold sink after cooling and hardening, thereby completing the high-temperature forming operation of the quartz glass.

As mentioned above, regarding the adjustment of the top block 4, it is preferred to have the following structure:

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 one by one;

Each top block 4 is provided with a connection assembly for connecting with an adjacent top block 4, and the connection 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;

A first slider 16 is slidably connected to the bottom of the L-shaped block 3, 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 arranged 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 two sets of inclined surfaces of the two triangular blocks are slidably matched respectively;

A double-headed screw rod 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 and connected to the two ends of the corresponding double-headed screw rod 7 .

As can be seen from the above, initially the upper surfaces of the plurality of top blocks 4 coincide with the upper surfaces of the support frame 5, and the two second sliding blocks 17 arranged under each column of the top blocks 4 are located at both ends, and then the top blocks 4 of each column are adjusted row by row, and the specific operation is as follows: first, the fixing blocks 20 at both ends of the support frame 5 extend into the through holes 19 of the top blocks 4 at both ends, so that the top blocks 4 at both ends are relatively fixed with the support frame 5, that is, the upper surfaces coincide, and then the double-headed screw 7 is rotated to make the two second sliding blocks 17 at both ends move toward the middle at the same time, and the one side inclined surfaces of the triangular blocks at the top of the two second sliding blocks 17 respectively conflict with the one side inclined surfaces of the triangular blocks at the bottom of the two first sliding blocks 16 in the top blocks 4 at both ends, so that the two second sliding blocks 17 respectively push the two first sliding blocks 16 to drive the two L-shaped card blocks 3 to move toward the middle, so that the two L-shaped card blocks 3 respectively slide and extend into the through holes 19 of the corresponding two adjacent top blocks 4, so that the top block 4 is fixed with the adjacent top blocks 4 in the vertical direction, until one side of the L-shaped card block 3 conflicts with the inner wall of one side of the top block 4, and then continue 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 to compress the spring 18 until the first slider 16 is completely retracted above the second slider 17, and the second slider 17 continues to move to the inner side of the first slider 16, and 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 that 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 connections of the top blocks 4, and then the top blocks 4 that are not connected in the middle are slid downward to the bottom to contact with the bottom of the support frame 5, so as to control the width of the mold sink.

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

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, and the two second sliders 17 are moved to both ends by rotating the double-headed screw 7 in the opposite direction, and the other side of the inclined surface of the triangular block at the top of the second slider 17 contacts the other side of the 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 , thereby realizing the disconnection between two adjacent top blocks 4, and then continue to move the second slider 17 to both ends, and the other side inclined surface of the triangular block on the top of the second slider 17 slides with the other side 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, and at the same time, repeats the above operation for the first slider 16 that passes through in the process of moving, so as to realize the disconnection of multiple card blocks 4 from both ends of the middle part in turn, so as to facilitate the next mold assembly to be reassembled into mold sinks of different sizes.

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:

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 to slide with the limiting rods 14;

A closed space is formed between the support frame 5 and the plurality of top blocks 4, an air intake pipe 6 and an air exhaust pipe 9 are fixedly passed through one side of the support frame 5, and one end of the air intake pipe 6 and the air exhaust pipe 9 extends into the closed space;

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

As can be seen from the above, the air inlet pipe 6 and the exhaust pipe 9 are preferably connected to the external blower and the exhaust fan respectively (not shown in the figure). At the beginning, the upper surfaces of the multiple top blocks 4 need to be overlapped 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, and 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 conflicts with 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 pressed and formed, thereby completing the automatic demoulding of the quartz glass and improving efficiency;

After the mold assembly is adjusted and connected, 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 closed space, so that the air pressure in the closed space gradually decreases, so that the external air pressure pushes 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;

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 external air can be accelerated by a blower or an exhaust fan, so that heat conduction and cooling can be performed through the top block 4, thereby accelerating the cooling and hardening of the quartz glass and improving the processing efficiency.

In addition, a screw rod 15 is rotatably connected in the box body 1, and a slide seat 8 is screwed on the screw rod 15, and the bottom of the support frame 5 is fixedly connected to the slide seat 8; a motor 21 is fixedly installed 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 screw rod 15 is driven to rotate by the motor 21, so that the screwed slide seat 8 slides in the box body 1, so that the slide seat 8 drives the support frame 5 to move to the outside of the box body 1, so that multiple top blocks 4 and quartz glass are all moved to the outside of the box body 1. At this time, the staff can complete the unloading of quartz glass and the loading of quartz glass raw materials outside the box body 1, avoiding the need for the staff to reach into the box body 1 for operation, thereby avoiding the high temperature in the box body 1 from causing burns to the staff, and improving safety.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
