With the acceleration of industrialization and continuous advancements in manufacturing technology, the demand for bolts is increasing daily, simultaneously placing higher demands on their processing precision, quality, and efficiency. Hot pressing is a process that involves heating materials to a plastic state and then applying pressure through a mold to shape them. In bolt processing, hot pressing technology offers significant advantages, such as high forming precision, high material utilization, and high production efficiency. By precisely controlling parameters such as heating temperature, pressure, and forming time, bolt products meeting specific requirements can be produced.

The lower mold is connected to two telescopic cylinders. The lower mold has a split assembly structure. The lower mold can be installed and fixed at the output end of the telescopic cylinders via a connecting frame for easy disassembly. A cooling groove and a cooling rod are provided at the bottom. The cooling rod, which is kept at a low temperature by the coolant in the cavity plate, can be inserted into the cooling groove of the lower mold to quickly cool the lower mold and facilitate bolt demolding. It has a good performance.

[0004] When using the aforementioned patent, since the cooling of the bolts is accelerated by the cooling rod, manual operation is still required when demolding the formed bolts. Manual demolding may damage the mold or product due to uneven force or improper operation. In addition, manual demolding is inefficient and cannot meet the needs of large-scale production.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1 to 6 As shown, this utility model provides an automatic hot pressing forming equipment for bolt processing, including a base plate 1, a support column 2 on the top of the base plate 1, a top plate 3 on the top of the support column 2, and a lower mold on the top of the base plate 1. The lower mold includes a fixed mold 4 on the top of the base plate 1 and a movable mold 7 that can move horizontally along the base plate 1. A horizontal driving component for driving the movable mold 7 to move is provided on the top of the base plate 1. When the horizontal driving component drives the movable mold 7 to fully abut against the fixed mold 4, a sealed chamber for placing bolt processing materials is formed between the movable mold 7 and the fixed mold 4. A second linear actuator 8 is provided on the top of the top plate 3. An upper mold 9 is provided at the working end of the second linear actuator 8. Heating pipes 11 are provided in both the movable mold 7 and the fixed mold 4. A demolding assembly 12 is provided in the sealed chamber. The demolding assembly 12 includes a threaded sleeve 1201 that can move vertically along the sealed chamber and a vertical driving component for driving the threaded sleeve 1201 to move. A cooling assembly 13 for accelerating cooling is also provided in both the movable mold 7 and the fixed mold 4.

[0025] First, the movable mold 7 is moved towards the fixed mold 4 by a horizontal drive component until the movable mold 7 and the fixed mold 4 are fully abutted, forming a sealed chamber. The bolt processing material is then placed inside the sealed chamber. The heating element 11 starts working, raising the bolt processing material inside the sealed chamber to the temperature required for hot pressing. Once the bolt processing material reaches the set temperature, the second linear actuator 8 on the top plate 3 starts working. The second linear actuator 8 is a cylinder, driving the upper mold 9 downwards, applying pressure to the bolt processing material inside the sealed chamber. Under the action of high temperature and high pressure, the bolt processing material gradually forms the desired bolt shape. After hot pressing is completed, the heating element 11 stops heating, and the cooling component 13 starts working, accelerating the cooling process of the formed bolt, allowing the formed bolt to cool and solidify quickly, improving production efficiency. After cooling is complete, the demolding component 12 starts working. The vertical drive component in the demolding assembly 12 drives the threaded sleeve 1201 to move along the vertical direction of the sealed chamber, pushing the forming bolt out of the mold and completing the demolding process. This prevents manual demolding from damaging or deforming the forming bolt and improves the demolding efficiency.

[0026] See Figures 4 to 5As shown, the vertical drive component includes an extension frame 1202; the extension frame 1202 is located at the bottom of the base plate 1, the top of the extension frame 1202 is provided with a drive threaded post 1203, the bottom of the extension frame 1202 is provided with a motor 1204, the output end of the motor 1204 is connected to the drive threaded post 1203, the drive threaded post 1203 is fitted with a drive gear 1205, the top of the base plate 1 is also provided with three sets of driven threaded posts 1206, the three sets of driven threaded posts 1206 and the drive threaded post 1203 are arranged in a rectangular array, the drive threaded post 1203 and the three sets of driven threaded posts 1206 are all threadedly connected with threaded sleeves 1201, the three sets of driven threaded posts 1206 are all fitted with driven gears 1207, and the drive gear 1205 and the driven gear 1207 are fitted with chains 1208.

[0027] The motor 1204 is started, driving the active threaded column 1203 to rotate. As the active gear 1205 rotates with the active threaded column 1203, it drives three sets of driven gears 1207 to rotate synchronously via the chain 1208. The three sets of driven gears 1207 then drive three sets of driven threaded columns 1206 to rotate synchronously. When the active and driven threaded columns 1203 and 1206 rotate, the threaded sleeve 1201 moves axially along them. As the threaded sleeve 1201 moves upward, it pushes the forming bolt, causing it to disengage from the lower mold, thus completing the demolding process. This prevents damage or deformation to the forming bolt caused by manual demolding, improving demolding efficiency. Simultaneously, because the active threaded column 1203 and the three sets of driven threaded columns 1206 are arranged in a rectangular array, the four threaded sleeves 1201 can apply force evenly during demolding, avoiding deformation of the forming bolt due to uneven force.

[0028] See Figure 5 As shown, a sealing rubber gasket is provided on the top of the threaded sleeve 1201.

[0029] The sealing rubber gasket ensures a good seal between the threaded sleeve 1201 and the mold. During the hot pressing process, a certain pressure and temperature need to be maintained in the sealed cavity. The sealing rubber gasket effectively prevents heat and pressure leakage, ensuring the stability of the molding environment.

[0030] See Figure 6 As shown, the cooling assembly 13 includes a water outlet pipe 1302; both the movable mold 7 and the fixed mold 4 are provided with cooling tanks 1301, the water outlet pipe 1302 is located on one side of the movable mold 7, the water outlet pipe 1302 is connected to the cooling tank 1301, and a water pump 1303 is also provided on the water outlet pipe 1302.

[0031] After hot pressing is completed, coolant is poured into the cooling tank 1301. The coolant flows in the cooling tank 1301 and absorbs the heat of the lower mold and forming bolts, causing the temperature of the lower mold to drop rapidly. The cooled coolant is discharged from the outlet pipe 1302 through the water pump 1303. After cooling, it can be recycled again, thereby achieving rapid cooling and improving production efficiency.

[0032] See Figure 1 and Figure 3 As shown, the horizontal drive component includes a fixed plate 5 and a first linear actuator 6; the fixed plate 5 is disposed on the top of the base plate 1 and located on one side of the fixed mold 4; the first linear actuator 6 is disposed on one side of the fixed plate 5, and the working end of the first linear actuator 6 is connected to one side of the movable mold 7.

[0033] In the initial state, the movable mold 7 is separated from the fixed mold 4, leaving sufficient space between them for placing bolt processing materials. When thermoforming is required, the first linear actuator 6, which is a cylinder, is activated, pushing the movable mold 7 horizontally towards the fixed mold 4. Driven by the horizontal actuator, the movable mold 7 gradually approaches the fixed mold 4 until the two are fully abutted, forming a sealed chamber. At this point, the bolt processing material is enclosed within the sealed chamber, ready for thermoforming.

[0034] See Figure 1 and Figure 2 As shown, the bottom of the active module 7 is provided with a limit slider, and the base plate 1 has a limit groove for the movement of the limit slider.

[0035] When the first linear actuator 6 pushes the movable mold 7 to move horizontally, the movable mold 7 will move within the limiting groove through the limiting slider at the bottom, thereby improving the stability of the lower mold closing and opening.

[0036] See Figure 2 As shown, the upper mold 9 has sliding plates 10 on both sides, and the sliding plates 10 have openings for the support column 2 to move.

[0037] When the second linear actuator 8 drives the upper mold 9 to move downward, the upper mold 9 will cause the slide plate 10 to slide on the support column 2, thereby enhancing the stability of the movement of the upper mold 9.

[0038] First, the movable mold 7 is driven by a horizontal drive component to move towards the fixed mold 4 until the movable mold 7 and the fixed mold 4 are fully abutted, forming a sealed chamber. The bolt processing material is then placed inside the sealed chamber. The heating pipe 11 starts working, raising the bolt processing material inside the sealed chamber to the temperature required for hot pressing. Once the bolt processing material reaches the set temperature, the second linear actuator 8 on the top plate 3 starts working. The second linear actuator 8 is a cylinder, driving the upper mold 9 downwards, applying pressure to the bolt processing material inside the sealed chamber. Under high temperature and high pressure, the bolt processing material gradually forms the desired bolt shape. After hot pressing is completed, the heating pipe 11 stops heating. Coolant is poured into the cooling tank 1301, and by flowing within the cooling tank 1301, it absorbs the heat from the lower mold and the formed bolt, rapidly lowering the temperature of the lower mold. The cooled coolant is discharged from the outlet pipe 1302 through the water pump 1303, and can be recycled after cooling, thereby accelerating the cooling of the formed bolt and allowing it to solidify quickly, improving production efficiency. After cooling, the motor 1204 is started, driving the active threaded column 1203 to rotate. As the active gear 1205 rotates with the active threaded column 1203, it drives three sets of driven gears 1207 to rotate synchronously via the chain 1208. The three sets of driven gears 1207 then drive three sets of driven threaded columns 1206 to rotate synchronously. When the active and driven threaded columns 1203 and 1206 rotate, the threaded sleeve 1201 moves axially along them. As the threaded sleeve 1201 moves upward, it pushes the forming bolt, causing it to disengage from the lower mold, thus completing the demolding process. This prevents damage or deformation to the forming bolt caused by manual demolding and improves demolding efficiency. Simultaneously, because the active threaded column 1203 and the three sets of driven threaded columns 1206 are arranged in a rectangular array, the four threaded sleeves 1201 can apply force evenly during demolding, avoiding deformation of the forming bolt due to uneven force.
