Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, specifically to a CNC hot pressing molding equipment for plastic materials. Background Technology

[0002] As is well known, CNC plastic material thermoforming equipment is an automated device specifically designed to mold plastic materials into desired shapes by heating and applying pressure. This equipment uses numerical control technology (NC or CNC) to precisely control parameters such as temperature, pressure and time during the molding process, ensuring high production efficiency and high product quality.

[0003] Traditional thermoforming equipment requires workers to manually place the plastic material to be processed between the upper and lower molding seats and remove the finished product after molding. Since thermoforming involves a high temperature and high pressure environment, workers' direct contact with these areas increases the risk of injury. Furthermore, repetitive physical labor can easily lead to worker fatigue. If the equipment is accidentally started before the workers have completely evacuated, the arm or other body part that is placing the material may be trapped between the upper and lower molds, thereby increasing the accident rate and affecting work efficiency.

[0027] Preferably, in this embodiment, the pressure applying mechanism comprises two sets of air cylinders 9, two sets of air cylinders 9 are symmetrically installed on the top wall of the top base 6, and the two sets of symmetrically installed air cylinders 9 are started at the same time. The air cylinders 9 push the guide plate 7 to move downward along the slide rod 5, and drive the upper forming seat 8 to stably descend. Since the air cylinders 9 are symmetrically arranged, they can synchronously apply the same size of pressure, which ensures that the pressure between the upper forming seat 8 and the lower forming seat 4 is uniformly distributed. The design of symmetrically arranging the two sets of air cylinders 9 can ensure that the pressure is uniformly distributed on the surface of the mold, avoiding product defects caused by insufficient or excessive local pressure, such as uneven thickness, cracks, etc. Uniform pressure distribution not only improves the appearance quality of the product, but also enhances its physical properties, such as strength and durability. The double-cylinder 9 system provides a more stable power source.

[0028] Preferably, in this embodiment, the feeding and discharging device comprises a rectangular groove 10, a threaded rod 11, a sliding block 12 and a driving device. The rectangular groove 10 is longitudinally formed in the middle of the top wall of the bottom plate 3. The threaded rod 11 is rotatably installed in the rectangular groove 10. The sliding block 12 is threadedly installed on the threaded rod 11. The top wall of the sliding block 12 is fixedly connected with the bottom wall of the lower forming seat 4. One end of the threaded rod 11 penetrates through the side wall of the bottom plate 3 and is installed with the driving device. Before the equipment starts to work, the lower forming seat 4 is located at one end of the rectangular groove 10 (assuming it is the feeding end). The plastic material to be processed is placed on the lower forming seat 4. The operator or the automatic system places the plastic material on the lower forming seat 4. The driving device is started. The driving device drives the threaded rod 11 to rotate. Since there is a threaded connection between the sliding block 12 and the threaded rod 11, as the threaded rod 11 rotates, the sliding block 12 moves forward along the rectangular groove 10, i.e. towards the hot pressing area, while driving the lower forming seat 4 and the plastic material on it to move forward. When the sliding block 12 moves to the specified position, which is the position where the upper and lower forming seats 4 are aligned, the driving device stops running, preparing for the hot pressing operation. The design of the threaded rod 11 and the sliding block 12 can provide very precise position control, ensuring that each feeding and discharging operation is accurate. The threaded rod 11 driving mode is more stable and smooth than other transmission modes, reducing vibration and impact, which helps to protect the product and the equipment itself.

Since the four groups of guide grooves 14 symmetrically provided on the bottom of the lower forming seat 4 are in sliding connection with the four groups of guide bars 13 installed on the top wall of the bottom plate 3, when the lower forming seat 4 moves with the slider 12, the guide bars 13 guide the guide grooves 14 to move linearly along the predetermined path, ensuring that the lower forming seat 4 moves forward or backward stably. The limiting plates 15 installed at the two ends of the guide bars 13 not only prevent the guide grooves 14 from accidentally slipping off the guide bars 13, but also limit the stroke of the lower forming seat 4, avoiding damage to the equipment or affecting the production process due to excessive movement. When the lower forming seat 4 moves to the set position, the limiting plates 15 will prevent it from continuing to move forward, ensuring that it accurately reaches the target position every time. The design of the guide bars 13 and the guide grooves 14 ensures that the lower forming seat 4 always maintains the correct direction during movement, reducing the problem of inconsistent product quality caused by deviation from the track.

[0030] Preferably, in this embodiment, the second guide device includes limit frames 16, a rack 17 and a gear 18, the top wall of the base plate 3 is symmetrically installed with two sets of limit frames 16 along the axis of the lower forming seat 4, the rack 17 is installed in the limit frame 16, the gear 18 is rotatably installed on the left and right side walls of the lower forming seat 4, the gear 18 and the rack 17 are meshed and connected, when the driving device starts to rotate the threaded rod 11, the slider 12 drives the lower forming seat 4 to move forward and backward along the rectangular groove 10, in this process, the gear 18 installed on the left and right side walls of the lower forming seat 4 rolls along the rack 17 installed in the two sets of limit frames 16 on the top wall of the base plate 3, since the gear 18 and the rack 17 are meshed and connected, this design ensures that the lower forming seat 4 can only move linearly along the predetermined path, avoiding any lateral deviation or irregular movement, the cooperation of the gear 18 and the rack 17 not only provides additional directional control, but also ensures the synchronization of both sides, that is, when the lower forming seat 4 moves, the gears 18 on both sides will roll along the respective racks 17 at the same time and uniformly, thereby maintaining the balance and stability of the entire structure, the limit frame 16 not only provides an installation position for the rack 17, but also limits the movement range of the lower forming seat 4, preventing it from exceeding the predetermined working area, increasing the safety of the system, by using the precise meshing mechanism of the gear 18 and the rack 17, the second guide device significantly improves the accuracy of the movement of the lower forming seat 4, ensuring that it can accurately reach the designated position every time, which is crucial for producing high-quality products, the combination of the gear 18 and the rack 17 effectively reduces the shaking and deviation during movement, making the lower forming seat 4 highly stable throughout the working cycle, which helps to improve the quality consistency of the final product.

[0031] Preferably, in this embodiment, the driving device is a driving motor 19, the design of the driving motor 19 usually includes built-in shock absorption and noise reduction features, making the entire system run more smoothly and quietly, reducing the impact of vibration on product quality, which is particularly suitable for driving the rotation of the threaded rod 11.

[0032] Preferably, in this embodiment, the guide groove 14 and the guide strip 13 are both designed in a T shape, which provides a larger contact area, making the cooperation between the guide groove 14 and the guide strip 13 more tightly, effectively preventing the lateral deviation or tilting of the upper forming seat 8 and the lower forming seat 4 during movement, ensuring the high precision of the movement path.

[0033] Preferably, in this embodiment, the driving motor 19 is a servo motor, which can achieve extremely precise position control, with an error usually within a few microns, which is crucial for ensuring that the lower forming seat 4 can be accurately moved to the designated position every time, helping to improve the quality and consistency of the product.
