[0044] The purge assembly 7 can be used to clean the residue remaining on the top of the mold base assembly 8. The mold base assembly 8 and the ejector assembly 9 can cooperate with each other. When the mold base assembly 8 is operating, the ejector assembly 9 operates in coordination to discharge the pressed fiberglass. The pressure sensing assembly 10 can monitor the operation of the mold base assembly 8 and improve the overall stability of the equipment.

[0045] The purge assembly 7 includes: a dust cover 701, a motor 702, a rotating disk 703, a lifting frame 705, a nozzle 709, an air pump 712 and an air pipe 713. The dust cover 701 is fixedly connected to the top of the support platform 3. There are two motors 702 and they are fixedly installed on the inside of the dust cover 701. The rotating disk 703 is fixedly connected to one end of the drive shaft of the motor 702. The side of the rotating disk 703 away from the motor 702 is fixedly connected to the connecting shaft 704. The lifting frame 705 passes through the support platform 3 and is slidably connected to the support platform 3. The top of the lifting frame 705 is fixedly connected to a ring 706 adapted to the connecting shaft 704. The ring 706 is fixedly connected to the top of the support platform 3. 706 is slidably connected with a connecting shaft 1 704, the bottom end of the lifting frame 705 is fixedly connected to several connecting rods 1 707, the bottom end of the support platform 3 is fixedly connected to several connecting rods 2 708, the top end of the nozzle 709 is rotatably connected to the bottom end of the connecting rod 2 708, the top end of the nozzle 709 is fixedly connected to a slide rail 710, and the two sides of the bottom end of the connecting rod 1 707 are fixedly connected to the connecting shaft 2 711 adapted to the slide rail 710, the connecting shaft 2 711 is slidably connected to the slide rail 710, there are two air pumps 712 and they are fixedly installed on both sides of the top of the support platform 3, and the air pipe 713 is fixedly connected between the tail end of the nozzle 709 and the bottom end of the air pump 712.

[0046] When the glass fiber reinforced plastic is pressed and formed and ejected, some debris will remain on the top of the mold base assembly 8. Start the air pump 712, and supply air to the nozzle 709 through the air pipe 713 to blow the top of the mold base assembly 8. Start the motor 1 702 so that its drive shaft drives the rotating disk 703 to rotate. The connecting shaft 1 704 fixedly connected to one side of the rotating disk 703 is biased towards the center of the rotating disk 703. As the rotating disk 703 rotates, the height of the connecting shaft 1 704 will change back and forth. The connecting shaft 1 704 drives the lifting frame 705 to move up and down through the collar 1 706. The lifting frame 705 drives the connecting rod 1 707 at the bottom to slide back and forth in the slide rail 710 through the connecting shaft 2 711, so that the nozzle 709 rotates back and forth around the bottom end of the connecting rod 2 708, and adjusts its blowing angle so that the nozzle 709 can more comprehensively clean the debris on the top of the mold base assembly 8 to prevent it from affecting the next pressing of the glass fiber reinforced plastic.

[0047] The mold base assembly 8 includes: a support base 801, a second motor 802, a second synchronous wheel 804, a synchronous belt 805 and a mold base 806. The support base 801 is fixedly connected to both sides of the top of the fixed base plate 1, and a cavity is opened inside the support base 801. The second motor 802 is fixedly installed on the top of the fixed base plate 1. The drive shaft ends on both sides of the second motor 802 are fixedly connected to the first synchronous wheel 803. The second synchronous wheel 804 is rotatably connected to the inner side of the support base 801. The synchronous belt 805 is sleeved on the outside of the first synchronous wheel 803 and the second synchronous wheel 804. The mold base 806 is fixedly connected between the second synchronous wheel 804. A mold groove is opened at the top of the mold base 806, and a cavity is opened inside the mold base 806.

[0048] The ejection and blanking assembly 9 includes: a fixed shaft 901, a connecting ring 904, a rotating rod 905 and a support plate 906. The fixed shaft 901 passes through the cavity inside the mold base 806 and is fixedly connected between the support base 801. A thread groove 1 902 and a thread groove 2 903 are provided on the outside of the fixed shaft 901. The thread directions of the thread groove 1 902 and the thread groove 2 903 are opposite. There are two connecting rings 904 and they are respectively threadedly connected to the outside of the thread groove 1 902 and the thread groove 2 903. One end of the rotating rod 905 is rotatably connected to both sides of the connecting ring 904. The support plate 906 is slidably connected to the inner side of the mold base 806. The bottom end of the support plate 906 is rotatably connected to the other end of the rotating rod 905. The top of the support plate 906 is fixedly connected to the connecting shaft 3 907. The connecting shaft 3 907 passes through the bottom end of the mold groove and is slidably connected to the mold groove. The top of the connecting shaft 3 907 is fixedly connected to the ejection plate 908.

[0049] The pressure sensing component 10 includes: a connecting tube 1001, a spring 1003, a sliding rod 1004 and a second ring 1006. The connecting tube 1001 is fixedly connected to the support base 801 close to the side of the second motor 802. One end of the inside of the connecting tube 1001 is fixedly installed on the pressure sensor 1002. One end of the spring 1003 is fixedly connected to the side of the pressure sensor 1002. The sliding rod 1004 is slidably connected to the inner side of the connecting tube 1001. One end of the sliding rod 1004 is fixedly connected to the other end of the spring 1003. The other end of the sliding rod 1004 is fixedly connected to the connecting shaft 4 1005 close to the side of the second motor 802. The second ring 1006 is fixedly connected to both sides of the bottom end of the mold base 806. The second ring 1006 is adapted to the connecting shaft 4 1005 and is slidably connected to the connecting shaft 4 1005.

[0050] The hot pressing plate 6 can be pressed down by starting the hydraulic rod 5 to press the glass fiber reinforced plastic in the mold groove into shape. After the pressing is completed, the hot pressing plate 6 rises and resets.

[0051] Manually starting the second motor 802 causes the first synchronous wheel 803 to drive the second synchronous wheel 804 and the mold base 806 to rotate toward the lower material table 4 through the synchronous belt 805.

[0052] Since the fixed shaft 901 is fixed and cannot rotate, as the mold base 806 rotates, the restricted connecting ring 904 rotates on the outside of the thread groove 1 902 and the thread groove 2 903. Since the thread directions of the thread groove 1 902 and the thread groove 2 903 are opposite, the two connecting rings 904 approach each other during the rotation, causing the rotating rod 905 to rotate, pushing the support plate 906 to rise, so that the support plate 906 pushes the ejection plate 908 to rise through the connecting shaft 3 907, and ejects the formed fiberglass reinforced plastic product out of the mold base 806. Due to the rotation, the mold base 806 is tilted close to the unloading platform 4, and the fiberglass reinforced plastic product slides along the unloading platform 4 into the storage box to complete the unloading and storage.

[0053] During the rotation process, it is automatically controlled by the pressure sensing component 10. During the rotation of the mold base 806, the second ring 1006 rotates synchronously, and pushes the slide rod 1004 to slide into the connecting tube 1001 through the connecting shaft 4 1005, compressing the spring 1003. The spring 1003 transmits the pressure to the pressure sensor 1002. When the mold base 806 rotates to a suitable tilt angle, the pressure sensor 1002 records the pressure at this time. When this pressure value is monitored, the motor 2 802 is automatically stopped to drive it to run in the reverse direction. As the mold base 806 returns to its original position, the monitored pressure gradually decreases. The pressure sensor 1002 records the pressure value at this time. When this pressure value is monitored, the motor 2 802 is automatically locked to stop its rotation, so that the mold base 806 faces the hot pressing plate 6, which is convenient for the next pressing of the glass fiber reinforced plastics, thereby completing rapid unloading and resetting.

[0054] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0055] The hydraulic rod 5 in the equipment is connected to an external hydraulic system. Since the hydraulic system is common knowledge in this field and does not belong to the improved technical point of this case, it will not be described here in detail.

[0056] The pressure sensor 1002 is an existing product on the market, and its connection method and control method are both existing technologies, so they will not be described here in detail.

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
