DETAILED DESCRIPTION

[0035] In order to make the technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0036] Embodiment one: the present application provides a technical solution: refer to Figure 1 - with 10, the present application discloses a glass steel solidification forming device, including mould 1 and gas heating equipment 2, mould 1 is mainly divided into three parts of fence 11, a plurality of square blocks 12 and grid plate 13, a plurality of square blocks 12 are arranged in fence 11, and the spacing between adjacent two square blocks 12 and the spacing between square block 12 and the inner wall of fence 11 are equal, grid plate 13 is arranged in fence 11, and the outer peripheral wall of grid plate 13 is in contact with the inner wall of fence 11, the inner hole wall of grid plate 13 is in contact with the outer peripheral wall of corresponding square block 12, heating mechanism 3 is arranged between gas heating equipment 2 and grid plate 13 and in grid plate 13, heat dissipation mechanism 4 is arranged on fence 11, and sealing mechanism 5 is arranged on the top side of fence 11 and in fence 11.

[0037] In this embodiment, when the improved glass steel solidification forming device is used, the operator first removes the sealing of the opening of mould 1 by sealing mechanism 5, then pours the raw material into the gap between square block 12 and the inner wall of fence 11 and compacts the raw material, at this time, due to the constraint and limitation of fence 11, square block 12 and grid plate 13 on the raw material, the raw material in mould 1 forms a glass steel grid of a specific size;

[0038] After the above feeding operation in mould 1 is completed, the operator blocks the top end opening of mould 1 by sealing mechanism 5, then heat dissipation mechanism 4 continuously sucks out the gas from mould 1 and injects the gas into gas heating equipment 2 for gas heating treatment, then hot gas is injected into heating mechanism 3, the hot gas quickly exchanges heat with grid plate 13 and square block 12, so that grid plate 13 and square block 12 are relatively stably maintained at a specific temperature, then the hot gas flows back to mould 1 through heat dissipation mechanism 4, so that mould 1 is filled with hot gas, at this time, each part of the raw material exchanges heat with the hot gas in mould 1, grid plate 13 and square block 12 synchronously, and the raw material is quickly heated, so that the raw material quickly completes the heating and shaping operation to form a glass steel grid of a fixed shape, the raw material is in a closed and high-temperature environment, which can greatly reduce the heat dissipation of the raw material to the outside, and the harmful gas generated during heating of the raw material cannot escape to the outside due to the blockage of the closed space;

[0039] In the above process of heating and shaping the raw material, heat dissipation mechanism 4 can extract the gas with more residual heat in mould 1 and introduce the gas into gas heating equipment 2 for re-heating treatment, so that gas heating equipment 2 only needs to consume less energy to heat the gas to the predetermined temperature, thereby reducing the energy consumption of the equipment.

[0040] After the raw materials are heated and shaped, the heating mechanism 3 is disconnected from the gas heating device 2, and the heat dissipation mechanism 4 extracts the harmful gas in the mold 1 and guides it to a specific location for discharge. At this time, the negative pressure strength in the mold 1 gradually increases, and the sealing mechanism 5 automatically releases the constraint and positioning state of the grid plate 13. Then, due to the pulling of the negative pressure cavity on the grid plate 13, the grid plate 13 pushes the glass steel grid upwards from all positions on the bottom side of the glass steel grid, and the glass steel grid is pushed out of the mold 1, automatically completing the demolding process of the glass steel grid. This avoids the deformation and damage of the glass steel due to excessive force on some positions of the glass steel. Due to the constraint and positioning of the sealing mechanism 5 on the glass steel grid, the glass steel grid moves upwards to the outlet of the heat dissipation mechanism 4 and stops moving. At this time, the heating mechanism 3 continuously sucks the gas with lower temperature outside and blows it on the glass steel grid, quickly completing the cooling process of the glass steel grid, avoiding injury to the operator when taking the material, and the flowing gas can carry out the residual toxic gas in the mold 1.

[0041] In further preferred embodiments of the application, as shown in Figure 3 Figure 5 The bottom end opening of the enclosure 11 is fixedly provided with a plurality of support plates 14, and the spacing between adjacent two support plates 14 is equal. The top side of the support plate 14 is fixedly connected with the corresponding square block 12, and the grid plate 13 is located on the top side of the support plate 14. The top of the grid plate 13 is fixedly provided with a sealing ring 15, and the outer ring wall of the sealing ring 15 is in contact with the inner wall of the enclosure 11.

[0042] In this embodiment, the support plate 14 is arranged between the locked square block 12 and the enclosure 11, so that the bottom end opening of the enclosure 11 can exchange gas with the outside, avoiding the negative pressure cavity or high pressure cavity in the bottom end opening of the enclosure 11 affecting the movement of the grid plate 13 during the movement of the grid plate 13.

[0043] It should be noted that the inner hole wall of the grid plate 13 can be provided with a sealing ring to block the gap between the square block 12 and the grid plate 13, thereby enhancing the sealing strength between the grid plate 13 and the square block 12.

[0044] In further preferred embodiments of the application, as shown in Figure 4 Figure 5 and Figure 10 ​​As shown, the heating mechanism 3 comprises a flow guide groove 31, the grid plate 13 is a heat conducting plate, and the enclosure 11 is made of a heat insulation plate, the flow guide groove 31 is arranged at the middle position of the plate wall of the grid plate 13, the exhaust end of the gas heating device 2 is communicated with a first electrically controlled three-way valve 32, one end of the bottom side of the grid plate 13 is fixedly provided with a first flow guide shell 33, and the exhaust ends of the first flow guide shell 33 are inserted into the flow guide groove 31, the first flow guide shell 33 is in gap cooperation with the corresponding support plate 14 and the inner wall of the enclosure 11, and the bottom side of the first flow guide shell 33 is communicated with a first soft pipe 34, and the gas inlet end of the first soft pipe 34 is communicated with the exhaust end of the first electrically controlled three-way valve 32.

[0045] In the embodiment, the hot gas discharged by the gas heating device 2 is directly discharged into the first soft pipe 34 by the first electrically controlled three-way valve 32, and then is guided into the flow guide groove 31 by the first soft pipe 34, so that the hot gas is injected into the flow guide groove 31 from multiple positions at one end of the flow guide groove 31, thereby making the hot gas quickly fill the flow guide groove 31, and at this time, the hot gas is closely attached to the inner wall of the flow guide groove 31, so that the heat is quickly guided into the grid plate 13 through the contact surface between the hot gas and the flow guide groove 31, and the grid plate 13 is relatively stably maintained in a specific range.

[0046] In further preferable embodiments of the present application, as shown in Figure 1 , Figure 4 and Figure 6 , the heat dissipation mechanism 4 comprises a plurality of second soft pipes 41, the plurality of second soft pipes 41 are arranged at the other end of the bottom side of the grid plate 13, one end of each of the second soft pipes 41 is inserted into the flow guide groove 31 and is fixedly connected with the grid plate 13, the spacing between adjacent two second soft pipes 41 is equal, two flared grooves 42 are oppositely arranged on the inner wall of the top of the enclosure 11, the other end of each of the second soft pipes 41 is inserted into one end of the flared groove 42 and is fixedly connected with the enclosure 11, and the flared groove 42 is located above the square block 12.

[0047] In the embodiment, the gas flowing through the flow guide groove 31 flows into one end of the flared groove 42 from the second soft pipe 41, and because the amount of gas discharged from the open end of the flared groove 42 is limited, the hot gas quickly fills the flared groove 42, and the gas pressure in the flared groove 42 increases, so that the hot gas in the flared groove 42 is linearly and quickly discharged from the opening of the flared groove, to supplement the lost gas in the mold 1, and the gas discharge flow rate is relatively fast.

[0048] In further preferable embodiments of the present application, as shown in Figure 1 , Figure 4 and Figure 6As shown, the right side wall of the top of the enclosure 11 is fixedly provided with a second flow guide shell 43, and the inside of the second flow guide shell 43 is connected with the inside of the other end flared groove 42 through a plurality of connecting holes 44, and the second flow guide shell 43 is fixedly provided with an air pump 45, and the air inlet end of the air pump 45 is fixedly penetrated through the shell wall of the second flow guide shell 43, and the air outlet end of the air pump 45 is connected and provided with a second electrically controlled three-way valve 46, one air outlet end of the second electrically controlled three-way valve 46 is connected and provided with a connecting pipe 47, and the air outlet end of the connecting pipe 47 is connected and provided with a backflow air inlet end of the gas heating device 2, and the other air outlet end of the second electrically controlled three-way valve 46 is connected and provided with an exhaust pipe 48;

[0049] In the embodiment, after the hot gas is discharged into the mold 1, it moves to the other flared groove 42, and is sucked by the air pump 45 through the other flared groove 42 and the second flow guide shell 43, and then the gas with more heat is re-injected into the gas heating device 2 through the second electrically controlled three-way valve 46 and the connecting pipe 47 for heating and recycling of the gas;

[0050] After the heating and shaping of the raw materials are completed, the second electrically controlled three-way valve 46 controls the connection state between the air outlet end of the air pump 45 and the connecting pipe 47 to be disconnected, and makes the air outlet end of the air pump 45 connected with the exhaust pipe 48, at the same time, the gas heating device 2 stops running, and the first electrically controlled three-way valve 32 controls the connection state between the first soft pipe 34 and the air outlet end of the gas heating device 2 to be disconnected, at this time, the air pump 45 extracts the harmful gas in the mold 1 and injects it into the exhaust pipe 48, and then is guided to a specific position for discharge by the exhaust pipe 48, at the same time, the negative pressure strength in the inside of the mold 1, the inside of the first soft pipe 34 and the inside of the second flow guide shell 43 gradually increases.

[0051] In a further preferred embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 4 As shown, the sealing mechanism 5 includes a cover 51, which is arranged above the enclosure 11, and the bottom side of the cover 51 is fixedly provided with a soft ring 52, and the bottom side of the soft ring 52 is connected with the top side of the enclosure 11, and a limiting strip 513 is fixedly arranged at the middle position of the inner top side of the cover 51.

[0052] In the embodiment, when the raw materials are loaded, the operator first removes the cover 51 from the mold 1, and then pours the raw materials into the gap between the square block 12 and the inner wall of the enclosure 11 and compacts the raw materials, at this time, due to the constraint and limitation of the enclosure 11, the square block 12 and the grid plate 13 on the raw materials, the raw materials form a glass steel grid of a specific size in the mold 1, and then the operator places the cover 51 on the top side of the mold 1, and due to the action of the gravity of the cover 51, the soft pad is pressed downward, so that the bottom side of the soft pad is tightly attached to the top side of the enclosure 11, and the raw materials in the closed space are heated and shaped, and the harmful gas generated will not float out of the mold 1.

[0053] In further preferable embodiments of the present application, as shown in Figure 1 - Figure 3 Limiting grooves 53 are formed at the four corners of the soft ring 52 and the bottom side of the cover 51, and hemispherical blocks 54 are fixedly arranged at the four corners of the top side of the enclosure 11, and the top of each hemispherical block 54 is inserted into the corresponding limiting groove 53.

[0054] In the present embodiment, when the cover 51 is placed on the enclosure 11, if there is a certain positional deviation between the hemispherical blocks 54 and the limiting grooves 53, the cover 51 can be pushed along the arc surface of the hemispherical blocks 54 due to the mutual interference between the arc surface of the hemispherical blocks 54 and the inner ring edge of the limiting hole opening, so as to automatically adapt the position of the cover 51. After the cover 51 is placed on the mold 1, the cover 51 is stably placed at a specific position on the top side of the enclosure 11 due to the mutual interference between the hemispherical blocks 54 and the inner wall of the limiting groove 53 opening, thereby avoiding the mispositioning of the cover 51 and the mold 1 to affect the use of the cover 51.

[0055] In further preferable embodiments of the present application, as shown in Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 A plurality of positioning grooves 55 are formed on the left and right side walls of the bottom of the grid plate 13, and the spacing between adjacent two positioning grooves 55 is equal. Positioning rods 56 are slidingly and penetratively arranged on the plate wall of the bottom of the enclosure 11 at positions corresponding to the positioning grooves 55, and one end of each positioning rod 56 is obliquely arranged and inserted into the corresponding positioning groove 55. Two connecting rods 57 are oppositely arranged on the outer circumferential side of the enclosure 11, and each connecting rod 57 is fixedly connected with the corresponding positioning rod 56. A piston cylinder 58 is arranged at the middle position between the connecting rod 57 and the enclosure 11, and the cylinder bottom of the piston cylinder 58 is fixedly connected with the enclosure 11. A piston rod 59 is slidingly arranged in the piston cylinder 58, and the driving end of the piston rod 59 extends out of the corresponding piston cylinder 58 and is fixedly connected with the corresponding connecting rod 57.

[0056] In the present embodiment, the arrangement of the connecting rod 57 enables the piston rod 59 to perform the push-pull operation of multiple positioning rods 56 at one time, and the mutual interference between the positioning rod 56 and the inner wall of the positioning groove 55 enables the constraint positioning operation of the grid plate 13, thereby avoiding the upward movement of the grid plate 13 when it is not needed to move and affecting the use of the device.

[0057] In further preferable embodiments of the present application, as shown in Figure 4 and Figure 7As shown, a spring 510 is provided between the plug plate of the piston rod 59 and the inner wall of the corresponding piston cylinder 58, and the two ends of the spring 510 are fixedly connected to the corresponding piston rod 59 and the inner wall of the corresponding piston cylinder 58, respectively. A pressure-limiting valve 511 is installed on the outer peripheral wall of the piston cylinder 58, and the exhaust ends of the two pressure-limiting valves 511 are respectively connected to the interior of the corresponding second soft tube 41 and the interior of the second guide shell 43 through a conduit 512.

[0058] In this embodiment, as the negative pressure strength inside the mold 1, inside the first soft tube 34, and inside the second guide shell 43 gradually increases, the pressure difference across the pressure-limiting valve 511 gradually reaches a threshold value, thereby causing part of the gas in the piston cylinder 58 to flow out of the piston cylinder 58. The negative pressure chamber formed in the piston cylinder 58 pulls the piston rod 59 out of the piston cylinder 58 and compresses the spring 510 until the piston rod 59 and the pressure-limiting valve 511 conflict with each other. When the piston rod 59 extends from the piston cylinder 58, the positioning rod 56 is simultaneously pulled out of the positioning groove 55 through the connecting rod 57, thereby releasing the constrained positioning state of the grid plate 13. The device has a high degree of automation and does not require the operator to perform other operations.

[0059] After the restrained positioning state of the grid plate 13 is released, as the negative pressure intensity in the mold 1 further increases, the pressure difference between the upper and lower sides of the grid plate 13 further increases, thereby gradually increasing the thrust for pushing the grid plate 13 upward, until the grid plate 13 pushes the FRP grille out of the mold 1, completing the demoulding process of the FRP grille, and the FRP grille moving upward will not continue to move upward after contacting the limit bar 513. At this time, the FRP grille is located between the two flared grooves 42, and the position of the FRP grille is automatically adjusted without the operator having to perform other operations.

[0060] After the air pump 45 extracts most of the gas mixed with harmful gases in the mold 1, the first electrically controlled three-way valve 32 controls the first soft tube 34 to communicate with the outside and only opens half of the air inlet. At this time, due to the limited air intake at the second soft tube 41, the mold 1 is always in a negative pressure chamber, so that the grid plate 13 is always pushed upward, so that the fiberglass grille is stably located between the two flared grooves 42. At this time, the low-temperature gas flowing between the two flared grooves 42 blows on the grid plate 13, thereby quickly removing the heat from the grid plate 13, preventing the grid plate 13 from overheating and causing injury to the operator when removing the grid plate 13 from the mold 1. The flow of gas can also carry away the residual toxic gas in the mold 1. After the cooling operation of the grid plate 13 is completed, the air pump 45 stops running. At this time, as the gas in the mold 1 flows into the negative pressure chamber in the mold 1, the operator can directly remove the cover 51 from the mold 1 and remove the fiberglass grille in the mold 1.

[0061] Embodiment two: a glass steel solidification forming method, comprising a glass steel solidification forming device described above, specifically comprising the following steps:

[0062] Step one: the operator first removes the cover 51 from the mold 1, then pours the raw material into the mold 1, and compacts the raw material, then re-covers the cover 51 on the mold 1 to complete the sealing operation of the top opening of the mold 1, and the raw material feeding operation is completed;

[0063] Step two: after the feeding operation of step one is completed, the air pump 45 is started to continuously extract the gas in the mold 1 and inject it into the gas heating device 2 for heating treatment, then the hot gas flows back into the mold 1 through the first flexible pipe 34, the flow guide groove 31, the second flexible ring 52 and the flared groove 42 to supplement the lost gas in the mold 1, and during the process of the hot gas traveling in the mold 1 and the flow guide groove 31, the raw material and the gas quickly exchange heat to complete the heating and setting treatment of the raw material, forming a glass steel grid of a specific shape;

[0064] Step three: after the heating and setting of the raw material in step two is completed, the gas heating device 2 stops running, the first electrically controlled three-way valve 32 is closed, and the second electrically controlled three-way valve 46 controls the air pump 45 to communicate with the exhaust pipe 48, at this time the air pump 45 extracts the harmful gas in the mold 1 and guides it to a specific position through the exhaust pipe 48 for discharge, while the negative pressure strength in the mold 1 gradually increases, at this time part of the gas in the piston cylinder 58 flows out of the piston cylinder 58 through the pressure limiting valve 511 and the conduit 512, so that the negative pressure strength in the piston cylinder 58 is enhanced, thereby pulling the piston rod 59 out of the piston cylinder 58, and then pulling the positioning rod 56 out of the positioning groove 55 through the connecting rod 57 to release the constraint and positioning state of the grid plate 13, then the negative pressure cavity in the mold 1 pulls the grid plate 13 upward to push the glass steel grid out of the mold 1 to automatically complete the demolding process of the glass steel grid;

[0065] Step four: after the air pump 45 reaches a certain running time in step three, the first electrically controlled three-way valve 32 controls the first flexible pipe 34 to communicate with the outside, and the outside gas flows into the mold 1 through the first electrically controlled three-way valve 32, the first flexible pipe 34, the flow guide groove 31 and the flared groove 42, thereby continuously blowing the glass steel grid with the outside gas of lower temperature to quickly complete the cooling process of the glass steel grid, while the residual harmful gas in the mold 1 is carried away by the airflow.

[0066] Working principle: when the improved glass steel solidification forming device is used, the operator first removes the cover 51 from the mold 1, then the operator pours the raw material into the gap between the square block 12 and the inner wall of the enclosure 11 and compacts the raw material, at this time the enclosure 11, the square block 12 and the grid plate 13 constrain and limit the raw material, and the raw material in the mold 1 forms a glass steel grid of a specific size;

[0067] After the feeding of the above raw materials is completed, the operator places the cover 51 on the top side of the enclosure 11, while inserting the hemispherical block 54 into the limiting groove 53. At this time, due to the mutual interference between the hemispherical block 54 and the inner wall of the opening of the limiting groove 53, the cover 51 is stably placed at a specific position on the top side of the enclosure 11, and due to the action of the gravity of the cover 51 itself, the soft pad is pressed downward, so that the bottom side of the soft pad is tightly attached to the top side of the enclosure 11;

[0068] It should be noted that when the cover 51 is placed on the enclosure 11 again, if there is a certain positional deviation between the hemispherical block 54 and the limiting groove 53, due to the mutual interference between the curved surface of the hemispherical block 54 and the inner ring edge of the limiting hole opening, the cover 51 can be pushed along the curved surface of the hemispherical block 54 to automatically adapt the position of the cover 51;

[0069] After the installation of the cover 51 is completed, the operator controls the first soft pipe 34 and the gas pump 45 exhaust port to be connected to the exhaust end of the gas heating device 2 and the backflow end of the gas heating device 2 through the first electrically controlled three-way valve 32 and the second electrically controlled three-way valve 46, and simultaneously the gas pump 45 is started to continuously extract the gas in the second flow guide shell 43, so that a negative pressure cavity is continuously formed in the second flow guide shell 43, and the gas in the mold 1 continuously flows into the second flow guide shell 43 through the flared groove 42 and the connecting hole 44 to supplement the lost gas in the second flow guide shell 43. The gas extracted by the gas pump 45 is injected into the gas heating device 2 through the connecting pipe 47 for gas heating treatment, and then the heated hot gas is injected into the first flow guide shell 33 through the first soft pipe 34, and is injected into the flow guide groove 31 from the exhaust end of the first flow guide shell 33. Then the hot gas rapidly fills the flow guide groove 31 while traveling in the flow guide shell, and flows back to the mold 1 through the second soft pipe 41 and the flared groove 42 to supplement the lost gas in the mold 1. According to the above, a negative pressure cavity with low strength is continuously formed in the mold 1 and the cover 51 at this time, thereby exerting a downward pulling force on the cover 51. At this time, the soft ring 52 is shrunk and deformed due to the pressing of the cover 51, so that the bottom side of the soft ring 52 is tightly attached to the top side of the enclosure 11, thereby enhancing the sealing strength of the gap between the cover 51 and the enclosure 11;

[0070] During the process of the hot gas traveling in the flow guide groove 31, heat exchange is rapidly performed between the hot gas and the grid plate 13 through the large contact surface therebetween, so that the grid plate 13 is relatively stably maintained at a specific temperature. The heat exchange between the square block 12 and the grid plate 13 causes the square block 12 to be synchronously maintained at a specific temperature. According to the above, the positions of each part of the raw materials are respectively exchanged with the hot gas in the mold 1, the grid plate 13 and the square block 12, so that the heating treatment of the raw materials is rapidly performed, thereby causing the raw materials to rapidly complete the heating and shaping operation to form a glass steel grating with a fixed shape;

[0071] After the heating and setting of the above raw materials is completed, the second electrically controlled three-way valve 46 controls the communication state between the exhaust end of the air pump 45 and the connecting pipe 47 to be disconnected, and makes the exhaust end of the air pump 45 communicate with the exhaust pipe 48, at the same time, the gas heating device 2 stops running, and the first electrically controlled three-way valve 32 controls the communication state between the first soft pipe 34 and the exhaust end of the gas heating device 2 to be disconnected;

[0072] At this time, the air pump 45 injects the gas extracted from the mold 1 into the exhaust pipe 48, and the gas is guided by the exhaust pipe 48 to a specific position for discharge, at the same time, the negative pressure strength in the mold 1, the first soft pipe 34 and the second flow guide shell 43 gradually increases, after the pressure difference between the two ends of the pressure limiting valve 511 reaches the threshold value, part of the gas in the piston cylinder 58 flows out of the piston cylinder 58, and the negative pressure cavity formed in the piston cylinder 58 pulls the piston rod 59 outside the piston cylinder 58 and compresses the spring 510, until the piston rod 59 and the pressure limiting valve 511 are in contact with each other, at the same time, the piston rod 59 extends from the piston cylinder 58, the connecting rod 57 synchronously pulls the positioning rod 56 out of the positioning slot 55, and the constraint positioning state of the grid plate 13 is released;

[0073] It should be noted that during the process of the piston rod 59 pushing the positioning rod 56, the adhesion between the glass steel grid and the inner wall of the mold 1 limits the grid plate 13, so that the inner wall between the positioning rod 56 and the positioning slot 55 cannot be further increased;

[0074] After the constraint positioning state of the grid plate 13 is released, as the negative pressure strength in the mold 1 further increases, the pressure difference liquid on the upper and lower sides of the grid plate 13 further increases, so that the upward pushing force of the grid plate 13 gradually increases, until the grid plate 13 pushes the glass steel grid out of the mold 1 to complete the demolding process of the glass steel grid, and the glass steel grid cannot continue to move upward after contacting with the limiting strip 513, at this time, the glass steel grid is located between the two flared grooves 42;

[0075] After the air pump 45 extracts most of the mixed harmful gas in the mold 1, the first electrically controlled three-way valve 32 controls the first soft pipe 34 to communicate with the outside, and only half of the air inlet is opened, at this time, due to the limited air intake at the second soft pipe 41, the mold 1 is always a negative pressure cavity, so that the grid plate 13 is always subjected to an upward pushing force, so that the glass steel grid is stably positioned between the two flared grooves 42, at this time, the gas flowing between the two flared grooves 42 has a lower temperature, which blows on the grid plate 13, so as to quickly take away the heat on the grid plate 13, after the cooling operation of the grid plate 13 is completed, the air pump 45 stops running, at this time, as the negative pressure cavity in the mold 1 disappears quickly with the inflow of gas in the mold 1, the operator can directly take off the cover 51 from the mold 1, and take out the glass steel grid in the mold 1;

[0076] It should be noted that the negative pressure cavity in the mold 1 synchronously applies a same size pulling force to the cover 51 and the grid plate 13, and the pulling force pushing the grid plate 13 upwards is smaller than the suction force suffered by the grid plate 13 because the gravity of the grid plate 13 and the glass steel grid needs to be overcome, and the downward pressure suffered by the limiting strip 513 is the gravity of the limiting strip 513, the cover 51 and the soft pad plus the suction force suffered by the cover 51, so when the glass steel grid and the limiting strip 513 resist each other, the cover 51 still stably covers the top side of the fence 11.

[0077] When the strength of the negative pressure cavity in the mold 1 gradually decreases, the piston rod 59 extending out of the piston cylinder 58 is pushed into the piston cylinder 58 again due to the pushing of the spring 510 until the connecting rod 57 and the piston cylinder 58 resist each other, and the inclined end of the positioning rod 56 is inserted into the fence 11 again, and at the same time, the piston cylinder 58 sucks part of the gas from the second flow guide shell 43 and the second soft tube 41 through the pressure limiting valve 511 and the conduit 512 respectively, so as to restore the gas storage amount in the piston cylinder 58;

[0078] After the glass steel grid is taken out from the mold 1, the operator pushes the grid plate 13 downwards, and when the bottom edge of the grid plate 13 and the inclined surface of the positioning rod 56 resist each other, the positioning rod 56 can be squeezed into the plate wall of the fence 11 along the inclined surface of the positioning rod 56, and then when the positioning rod 56 is aligned with the positioning groove 55, the spring 510 pushes the positioning rod 56 into the positioning groove 55 again, and at this time, the constraint and positioning of the grid plate 13 are re-completed through the mutual resistance between the bottom side plane of the positioning rod 56 and the inner wall of the positioning groove 55 and the mutual resistance between the grid plate 13 and the support plate 14, and the position of the grid plate 13 in the mold 1 remains stable, and at this time, the operator can continuously perform the heating and shaping operation of the glass steel according to the above re-operation.
