When the inclined plane block 3 returns, the extrusion rod will clamp the inclined plane block 3 in the gap of the extrusion rod to prevent the sliding frame from moving when the molten material is injected. After the microcrystalline glass is formed, the electric telescopic rod is retracted to drive the upper mold to rise, so that the upper mold is separated from the lower mold. When the upper mold rises, it will drive the extrusion rod to contact the inclined surface of the inclined plane block 3, and extrude the inclined plane block 3 away from the lower mold.

The side walls of the four lifting rods are fixedly connected to the side walls of the sliding plate 2. Utilizing the force of the movement of the sliding frame, when the two sliding frames approach each other, it will drive connecting rod 1 to push sliding plate 1 to move, so that the rotating frame rotates and tilts, so that sliding plate 2 drops, and drives the lifting rod to drop, so that the lifting rod is flush with the top of the lower mold; when the sliding frame moves away from the lower mold, it will drive connecting rod 1 to move, so that sliding plate 1 moves; when sliding plate 1 moves, it will also slide on the inner wall of the rotating frame, drive the rotating frame to rotate, tilt the rotating frame, and drive sliding plate 2 to rise; when sliding plate 2 rises, it will drive the lifting rod to rise, so as to pre-lift the formed microcrystalline glass.
[0010] Preferably, the lifting mechanism also includes two fixed frames fixedly connected to the top of the lower mold, the inner walls of the two fixed frames are slidably connected with extrusion plates, the bottom of the two extrusion plates are fixed with two connecting rods 2, the side walls of the two connecting rods 2 are fixedly connected to the side walls of the sliding plate 2, the tops of the two fixed frames are through-connected with five air outlet pipes, the outer walls of the two fixed frames are slidably connected to the inner wall of the upper mold, and the force of the movement of the sliding plate 2 is utilized, when the sliding plate 2 rises, it will drive the connecting rod 2 to rise, and the connecting rod 2 will push the extrusion plate to rise, and when the extrusion plate moves, it will squeeze the gas in the fixed frame, and the squeezed gas will enter the air outlet pipe and be sprayed toward the top of the formed microcrystalline glass through the air outlet pipe. After the gas is sprayed, an air film can be formed between the formed microcrystalline glass and the mold, thereby preventing the part area of the microcrystalline glass from being closely attached to the lower mold during pre-lifting, reducing the direct contact between them, thereby reducing the adhesion.
[0011] A method for using a production mold for continuous production of glass-ceramics includes the following steps: S1: Suction multiple times to create a vacuum; S2: injecting gas into the bottom of the formed glass; S3: Pre-lift the formed glass.
[0012] The present invention has the following beneficial effects: (1) When the present invention is used, the staff connects the injection cavity with the injection tube. When it is necessary to produce microcrystalline glass, the electric telescopic rod is started to extend, driving the upper mold to descend and approach the lower mold, driving the molding block and the sliding rod to descend until they are in close contact with the upper mold and the lower mold. At the same time, the descent of the upper mold will also drive the rack to engage with the gear rod, causing the gear rod to rotate. When the gear rod rotates, it will drive the push block and the counterweight block to rotate, tightening the clockwork spring and accumulating rebound force. When the upper mold and the lower mold are in close contact, the rack will separate from the gear rod. At this time, the clockwork spring accumulates The stored resilience will be released, driving the push block to rotate. During the rotation process, the push block will contact the sliding rod, which will push the sliding rod up, driving the I-block to rise. When the I-block moves, it will squeeze the gas in the exhaust groove and discharge it from the exhaust pipe. At the same time, since the upper mold and the lower mold are in close contact, the gap between the two is in a sealed state. At this time, the inclined plane block 1 will block the air inlet groove of the I-block. When the I-block rises, it will inhale the gas in the gap between the lower mold and the upper mold. As the I-block moves, the inclined plane of the inclined plane block 2 will contact the inclined plane of the inclined plane block 1. Push the inclined block to move, open the air inlet slot, and allow the sucked gas to enter the exhaust slot, while squeezing the spring return rod. When the push block rotates and separates from the sliding rod, the sliding rod will drop, driving the I-block to drop until the push block lifts the sliding rod again, allowing the I-block to suck the gas in the gap between the lower mold and the upper mold again. The gas sucked in last time will be squeezed out when the I-block rises again. Because the injection cavity and the injection tube, and the filling material in the injection tube, it is difficult for gas to enter from the injection cavity, so the lower mold can be The gas in the gap between the I-block is reduced. When the rebound force of the clockwork spring is released, the weight of the counterweight block will cause the push block to point upward, thereby lifting the sliding rod and making the bottom of the I-block flush with the bottom of the upper mold. Then the molten material can be injected through the injection cavity. Since there is less gas in the gap between the lower mold and the upper mold, the molten material is less hindered during the flow process, so that the molten material can reach every corner of the mold faster, reducing the possibility of incomplete filling or bubble generation, which makes it easier for the molten material to fill the mold quickly.
[0013] (2) The present invention utilizes the force of the upper mold moving. When the upper mold descends, it also drives the extrusion rod to descend. Since the spring return rod 2 is in an extrusion state at this time, the extrusion rod will separate from the inclined block 3, and the rebound force of the spring return rod 2 will be released, so that the sliding frame returns to its original position and fits together with the descending upper mold, driving the arc block to return to its original position, so that the two arc blocks fit together. When the inclined block 3 returns to its original position, the extrusion rod will clamp the inclined block 3 in the gap of the extrusion rod to prevent the sliding frame from moving when the molten material is injected. After the microcrystalline glass is formed, the electric telescopic rod is retracted to drive the upper mold to rise, so that the upper mold is separated from the lower mold. When the upper mold rises, it will drive the extrusion rod to move. The rod contacts the inclined surface of the inclined surface block three, squeezing the inclined surface block three away from the lower mold, driving the spring reset rod two to move, allowing the spring reset rod two to accumulate resilience, and at the same time, driving the sliding frame and the arc block to return to their positions, allowing the two arc blocks to separate. Since the fixed plate is in a stationary state, when the sliding frame moves, the fixed plate will squeeze the gas in the sliding frame into the arc block, and discharge from the arc block into the arc groove, allowing the gas to enter the bottom of the formed microcrystalline glass, preventing the microcrystalline glass from being formed. After the molding, a vacuum may be formed between the microcrystalline glass and the mold, resulting in difficulty in demolding the glass. By injecting gas, the vacuum can be broken, the adsorption force can be reduced, and demolding can be smoother.
[0014] (3) The present invention utilizes the force of the movement of the sliding frame. When the two sliding frames approach each other, it will drive the connecting rod 1 to push the sliding plate 1 to move, so that the rotating frame rotates and tilts, causing the sliding plate 2 to drop, driving the lifting rod to drop, and making the lifting rod flush with the top of the lower mold. When the sliding frame moves away from the lower mold, it will drive the connecting rod 1 to move, causing the sliding plate 1 to move. When the sliding plate 1 moves, it will also slide on the inner wall of the rotating frame, driving the rotating frame to rotate, causing the rotating frame to tilt, and driving the sliding plate 2 to rise. When the sliding plate 2 rises, it will drive the lifting rod to rise, and pre-lift the microcrystalline glass after molding. The pre-lifting can help reduce the contact force between the microcrystalline glass and the mold, thereby making demolding smoother, reducing the difficulty of demolding, and facilitating the removal of the molded microcrystalline glass.
[0015] (4) The present invention utilizes the force of the movement of the sliding plate 2. When the sliding plate 2 rises, it will drive the connecting rod 2 to rise. The connecting rod 2 will push the extrusion plate to rise. When the extrusion plate moves, it will squeeze the gas in the fixed frame. The squeezed gas will enter the air outlet pipe and be sprayed toward the top of the formed microcrystalline glass through the air outlet pipe. After the gas is sprayed, an air film can be formed between the formed microcrystalline glass and the mold, thereby preventing the microcrystalline glass from being tightly attached to the lower mold during pre-lifting, reducing the direct contact between them, and thus reducing the adhesion.

[0019] 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.
[0020] For example, see Figure 1 - Figure 6 The present invention is a production mold for continuous production of microcrystalline glass, comprising a power mechanism 1, the power mechanism 1 also includes a support platform 101, a lower mold 102 is fixedly connected to the top of the support platform 101, and an upper mold 103 is arranged on the top of the lower mold 102; The air outlet mechanism 2 includes two sliding frames 201 slidably connected to the top of the lower mold 102, the inner walls of the two sliding frames 201 are slidably connected to fixed plates 202, and the left and right sides of the upper mold 103 are respectively fixedly connected to extrusion rods 203; The lifting mechanism 3 includes two sliding grooves 301 opened on the inner wall of the lower mold 102. The parts contained in the two sliding grooves 301 are the same. The front and back sides of the two sliding frames 201 are fixedly connected with a connecting rod 302, and the inner wall of the sliding groove 301 is slidably connected with two sliding plates 303.
[0021] The power mechanism 1 also includes four positioning rods 104 fixedly connected to the top of the lower mold 102, the inner wall of the upper mold 103 is slidably connected to the outer wall of the four positioning rods 104, the four positioning rods 104 are grouped in pairs, the tops of the two groups of positioning rods 104 are fixedly connected to the electric telescopic rods 105, and the bottom output ends of the two electric telescopic rods 105 are fixedly connected to the top of the upper mold 103; Among them, an injection cavity 106 is opened at the center of the upper mold 103, and two exhaust grooves 107 are opened on the inner wall of the upper mold 103. The staff connects the injection cavity 106 with the injection tube. When microcrystalline glass needs to be produced, the electric telescopic rod 105 is started to extend, driving the upper mold 103 to descend and approach the lower mold 102.
[0022] The power mechanism 1 also includes an I-shaped block 108 slidably connected to the inner wall of the exhaust groove 107, the tops of the two I-shaped blocks 108 are fixedly connected with a sliding rod 109, the tops of the two I-shaped blocks 108 are slidably connected with a slope block 110, the inner walls of the two exhaust grooves 107 are fixedly connected with a slope block 2 111, and the side walls of the two slope blocks 1 110 are fixedly connected with a spring return rod 112; Among them, the outer walls of the two spring return rods 112 are slidably connected to the top of the I-shaped block 108, the left and right sides of the upper mold 103 are fixedly connected with racks 113 respectively, and the top of the support platform 101 is fixedly connected with two fixing frames 114.
[0023] The power mechanism 1 further includes a gear rod 115 rotatably connected to the inner wall of the fixing frame 114, the outer walls of the two gear rods 115 are meshed with the side walls of the rack 113, the outer walls of the two gear rods 115 are fixedly connected to a push block 117, and the outer walls of the two gear rods 115 are fixedly connected to a clockwork spring 116; Among them, two counterweight blocks 118 are fixedly connected to the side walls of the two pushing blocks 117, and four exhaust pipes 119 are connected to the top of the upper mold 103. The inner walls of the four exhaust pipes 119 are fixedly connected with exhaust check valves 120, which drive the I-shaped block 108 and the sliding rod 109 to descend until they are in close contact with the upper mold 103 and the lower mold 102. At the same time, the descent of the upper mold 103 will also drive the rack 113 to engage with the gear rod 115, so that the gear rod 115 rotates. When the gear rod 115 rotates, it will drive the pushing block 117 and the counterweight block 118 to rotate, so that the clockwork spring 116 is tightened and the rebound force is accumulated. When the upper mold 103 is in close contact with the lower mold 102, the rack 113 will engage with the gear rod 115. The gear rod 115 is separated, and the rebound force accumulated in the clockwork spring 116 will be released, driving the push block 117 to rotate. The push block 117 will contact the sliding rod 109 during the rotation process, and will push the sliding rod 109 to rise, driving the I-shaped block 108 to rise. When the I-shaped block 108 moves, it will squeeze the gas in the exhaust groove 107 and discharge it from the exhaust pipe 119. At the same time, since the upper mold 103 and the lower mold 102 are in close contact, the gap between the two is in a sealed state, and at this time, the inclined plane block 110 will block the air inlet groove of the I-shaped block 108. When the I-shaped block 108 rises, it will inhale the gas in the gap between the lower mold 102 and the upper mold 103. As the I-shaped block 108 moves, the inclined plane The inclined surface of the second block 111 will contact the inclined surface of the inclined surface block 110, pushing the inclined surface block 110 to move, so that the air inlet slot is opened, so that the sucked gas enters the exhaust slot 107, and at the same time squeezes the spring return rod 112. When the push block 117 rotates and separates from the sliding rod 109, the sliding rod 109 will drop, driving the I-shaped block 108 to drop until the push block 117 lifts the sliding rod 109 again, so that the I-shaped block 108 can suck the gas in the gap between the lower mold 102 and the upper mold 103 again. The gas sucked last time will be squeezed out when the I-shaped block 108 rises again. Since the injection cavity 106 and the injection tube, and the filling material in the injection tube, the injection cavity 106 is filled with material. 6 is difficult for gas to enter, so that the gas in the gap between the lower mold 102 and the I-block 108 can be reduced. When the rebound force of the clockwork spring 116 is released, the weight of the counterweight block 118 will make the push block 117 face upward, so that the push block 117 pushes up the sliding rod 109, so that the bottom of the I-block 108 is flush with the bottom of the upper mold 103, and then the molten material can be injected through the injection cavity 106. Since there is less gas in the gap between the lower mold 102 and the upper mold 103, the molten material is less hindered in the flow process, so that the molten material can reach every corner of the mold faster, reducing the possibility of incomplete filling or bubble generation, so that the molten material can quickly fill the mold.
[0024] For example 2, please refer to Figure 7 - Fig.12The present invention is a production mold for continuous production of microcrystalline glass. On the basis of the first embodiment, the air outlet mechanism 2 further includes a second spring return rod 204 fixedly connected to the side wall of the sliding frame 201, and the side walls of the two second spring return rods 204 are fixedly connected with a third inclined surface block 205. The top of the lower mold 102 is provided with an arc groove 206, and the bottoms of the two sliding frames 201 are fixedly connected with arc blocks 207; The bottoms of the two arc blocks 207 are slidably connected to the tops of the arc grooves 206, and the side walls of the two fixed plates 202 are fixedly connected to the inner walls of the lower mold 102. The force of the upper mold 103 moving will drive the extrusion rod 203 to descend when the upper mold 103 descends. Since the spring return rod 204 is in an extruded state at this time, the extrusion rod 203 will be separated from the inclined plane block 3 205, and the rebound force of the spring return rod 204 will be released, so that the sliding frame 201 returns to its original position and fits together with the descending upper mold 103, driving the arc The arc block 207 returns to its original position, allowing the two arc blocks 207 to fit together. When the inclined plane block three 205 returns to its original position, the extrusion rod 203 will clamp the inclined plane block three 205 in the gap of the extrusion rod 203 to prevent the sliding frame 201 from moving when the molten material is injected. After the microcrystalline glass is formed, the electric telescopic rod 105 is retracted to drive the upper mold 103 to rise, so that the upper mold 103 is separated from the lower mold 102. When the upper mold 103 rises, it will drive the extrusion rod 203 to contact the inclined surface of the inclined plane block three 205, squeezing the inclined plane block three 205 away from the lower mold 102.
[0025] The lifting mechanism 3 also includes a rotating frame 304 rotatably connected to the inner wall of the sliding groove 301, the inner walls of the two rotating frames 304 are slidably connected to the side walls of the sliding plate 1 303, the inner wall of the sliding groove 301 is slidably connected to two sliding plates 2 305, and the tops of the two sliding plates 2 305 are slidably connected to the inner wall of the rotating frame 304; Among them, four moving grooves 306 are opened on the inner wall of the lower mold 102, and the inner walls of the four moving grooves 306 are slidably connected with lifting rods 307. The side walls of the four lifting rods 307 are fixedly connected to the side walls of the sliding plate 2 305. By using the force of the sliding frame 201 moving, when the two sliding frames 201 approach each other, the connecting rod 1 302 will be driven to push the sliding plate 1 303 to move, so that the rotating frame 304 rotates and tilts, so that the sliding plate 2 305 descends, driving the lifting rods 307 descends, allowing the lifting rod 307 to be flush with the top of the lower mold 102. When the sliding frame 201 moves away from the lower mold 102, it will drive the connecting rod 1 302 to move, allowing the sliding plate 1 303 to move. When the sliding plate 1 303 moves, it will also slide on the inner wall of the rotating frame 304, driving the rotating frame 304 to rotate, causing the rotating frame 304 to tilt, and driving the sliding plate 2 305 to rise. When the sliding plate 2 305 rises, it will drive the lifting rod 307 to rise, and pre-lift the formed microcrystalline glass.
[0026] The lifting mechanism 3 also includes two fixed frames 309 fixedly connected to the top of the lower mold 102, and the inner walls of the two fixed frames 309 are slidably connected with an extrusion plate 310, and the bottoms of the two extrusion plates 310 are fixed with two connecting rods 308, and the side walls of the two connecting rods 308 are fixedly connected to the side walls of the sliding plate 305, and the tops of the two fixed frames 309 are connected with five outlet pipes 311, and the outer walls of the two fixed frames 309 are slidably connected to the inner wall of the upper mold 103. The sliding plate 305 is used to move the force of the sliding plate 305. When the second rod 305 rises, it will drive the second connecting rod 308 to rise, and the second connecting rod 308 will push the extrusion plate 310 to rise. When the extrusion plate 310 moves, it will squeeze the gas in the fixed frame 309. The squeezed gas will enter the air outlet pipe 311 and be sprayed toward the top of the formed microcrystalline glass through the air outlet pipe 311. After the gas is sprayed out, an air film can be formed between the formed microcrystalline glass and the mold, thereby preventing the part of the microcrystalline glass from fitting closely with the lower mold 102 during pre-lifting, reducing the direct contact between them, and thus reducing the adhesion.
[0027] The method for using the production mold for continuous production of microcrystalline glass includes the following steps: S1: Suction multiple times to create a vacuum; S2: injecting gas into the bottom of the formed glass; S3: Pre-lift the formed glass.
[0028] A specific application of this embodiment is as follows: when the present invention is used, the staff connects the injection cavity 106 with the injection tube. When it is necessary to produce microcrystalline glass, the electric telescopic rod 105 is started to extend, driving the upper mold 103 to descend and approach the lower mold 102, driving the I-shaped block 108 and the sliding rod 109 to descend until they are in close contact with the upper mold 103 and the lower mold 102. At the same time, the descent of the upper mold 103 will also drive the rack 113 to engage with the gear rod 115, so that the gear rod 115 rotates. When the gear rod 115 rotates, it will drive the push block 117 and the counterweight block 118 to rotate, so that the clockwork spring 116 is tightened and the resilience is accumulated. When the upper mold 103 is in close contact with the lower mold 102, the rack 113 The gear rod 115 will be separated from the gear rod 115. At this time, the resilience of the clockwork spring 116 will be released, driving the push block 117 to rotate. The push block 117 will contact the sliding rod 109 during the rotation process, and will push the sliding rod 109 to rise, driving the I-shaped block 108 to rise. When the I-shaped block 108 moves, the gas in the exhaust groove 107 will be squeezed and discharged from the exhaust pipe 119. At the same time, since the upper mold 103 and the lower mold 102 are in close contact, the gap between the two is in a sealed state, and at this time, the inclined surface block 110 will block the air inlet groove of the I-shaped block 108. When the I-shaped block 108 rises, the gas in the gap between the lower mold 102 and the upper mold 103 will be sucked in. With the movement of the I-shaped block 108, the inclined surface block 110 will block the air inlet groove of the I-shaped block 108. The inclined surface of the second surface block 111 will contact the inclined surface of the inclined surface block 110, pushing the inclined surface block 110 to move, so that the air inlet slot is opened, so that the sucked gas enters the exhaust slot 107, and at the same time squeezes the spring return rod 112. When the push block 117 rotates and separates from the sliding rod 109, the sliding rod 109 will drop, driving the protruding block 108 to drop until the push block 117 lifts the sliding rod 109 again, so that the protruding block 108 can suck the gas in the gap between the lower mold 102 and the upper mold 103 again. The gas sucked last time will be squeezed out when the protruding block 108 rises again. Since the injection cavity 106 and the injection tube, and the filling material in the injection tube, the injection cavity 106 is filled with material. 6, it is difficult for gas to enter, so that the gas in the gap between the lower mold 102 and the I-shaped block 108 can be reduced. When the rebound force of the clockwork spring 116 is released, the weight of the counterweight block 118 will make the push block 117 face upward, so that the push block 117 pushes up the sliding rod 109, so that the bottom of the I-shaped block 108 is flush with the bottom of the upper mold 103, and then the molten material can be injected through the injection cavity 106. Since there is less gas in the gap between the lower mold 102 and the upper mold 103, the molten material is less hindered during the flow process, so that the molten material can reach every corner of the mold faster, reducing the possibility of incomplete filling or bubble generation, so that the molten material can quickly fill the mold; Secondly, when the upper mold 103 descends, it will also drive the extrusion rod 203 to descend. Since the spring return rod 204 is in an extrusion state at this time, the extrusion rod 203 will separate from the inclined block 3 205, and the resilience of the spring return rod 204 will be released, so that the sliding frame 201 returns to its original position and fits together with the descending upper mold 103, driving the arc block 207 to return to its original position, so that the two arc blocks 207 fit together. When the inclined block 3 205 returns, the extrusion rod 203 will clamp the inclined block 3 205 in the gap of the extrusion rod 203 to prevent the sliding frame 201 from moving when the molten material is injected. After the microcrystalline glass is formed, the electric telescopic rod 105 is retracted to drive the upper mold 103 to rise, so that the upper mold 103 is separated from the lower mold 102. When the upper mold 103 rises, it will drive the extrusion rod 203 contacts the inclined surface of the inclined surface block 3 205, squeezes the inclined surface block 3 205 away from the lower mold 102, drives the spring return rod 204 to move, and allows the spring return rod 204 to accumulate resilience. At the same time, it drives the sliding frame 201 and the arc block 207 to return to their original positions, so that the two arc blocks 207 are separated. Since the fixed plate 202 is in a stationary state, when the sliding frame 201 moves, the fixed plate 202 squeezes the gas in the sliding frame 201 and enters the arc block 207, and is discharged from the arc block 207 into the arc groove 206, so that the gas enters the bottom of the formed microcrystalline glass, preventing the microcrystalline glass from being formed. It may also form a vacuum between the microcrystalline glass and the mold after the microcrystalline glass is formed, which makes it difficult to demold the glass. By injecting gas, the vacuum can be broken, the adsorption force can be reduced, and the demolding can be smoother. Secondly, when the two sliding frames 201 are close to each other, the connecting rod 1 302 will be driven to push the sliding plate 1 303 to move, so that the rotating frame 304 rotates and tilts, so that the sliding plate 2 305 drops down, and drives the lifting rod 307 to drop down, so that the lifting rod 307 is flush with the top of the lower mold 102. When the sliding frame 201 is away from the lower mold 102, it will drive the connecting rod 1 302 to move, so that the sliding plate 1 303 moves. When the sliding plate 1 303 moves, it will also slide on the inner wall of the rotating frame 304, driving the rotating frame 304 to rotate, so that the rotating frame 304 tilts, and drives the sliding plate 2 305 to rise. When the sliding plate 2 305 rises, it will drive the lifting rod 307 to rise, and the formed micro-ceramics will be pre-lifted. The pre-lifting can help reduce the contact force between the micro-ceramics and the mold, so that demolding is smoother, reducing the difficulty of demolding, and facilitating the removal of the formed micro-ceramics. Secondly, when the sliding plate 305 rises, it will drive the connecting rod 308 to rise, and the connecting rod 308 will push the extrusion plate 310 to rise. When the extrusion plate 310 moves, it will squeeze the gas in the fixed frame 309. The squeezed gas will enter the air outlet pipe 311 and be sprayed toward the top of the formed microcrystalline glass through the air outlet pipe 311. After the gas is sprayed out, an air film can be formed between the formed microcrystalline glass and the mold, thereby preventing the part of the microcrystalline glass from being tightly fitted with the lower mold 102 during pre-lifting, reducing the direct contact between them, and thus reducing the adhesion.
