By setting up a modular box, when a module needs to be replaced, simply remove the top mold frame, pull the push plate, and move the insert rod and locking block upwards. The telescopic spring releases its elastic potential energy, causing the fixed ring to displace, thereby moving the movable rod and the fixed block to the outside of the modular box, thus allowing the mold stored in the modular box to be extracted. After replacement, simply push the modular box into the bottom mold frame, push the push plate, compress the telescopic spring, and move the fixed block into the modular box, fixing the modular box in the bottom mold frame.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 The diagram shows a quick-release mold frame, including a lower base 1. The lower base 1 has a lower groove at its top, and a lower mold 18 is magnetically attached to the lower groove via a magnetic suction component. A frame 15 is integrally connected to the top edge of the lower mold 18. A top groove 14 is opened in the middle of the left and right ends of the top of the frame 15. A top bar 13 is inserted into the top groove 14. The power input end of the top bar 13 on both sides is connected to the power output end of a bidirectional threaded drive component via a slide rod 11. The quick-release mold frame disclosed in this utility model is embedded in the lower groove by the magnetic suction component, and the top bar 13 driven by the bidirectional threaded drive component is limited, which facilitates the automatic and quick disassembly of the lower mold 18. The mold frame can be adapted to different lower molds 18 and can be recycled.

[0021] Furthermore, the upper seat 3 is fixedly connected to the top four corners of the lower seat 1 via columns 2, and the upper mold 5 is connected to the bottom center of the upper seat 3 via an electric telescopic rod 4 for easy installation; furthermore, the lower seat 1 has sliding grooves 12 at both ends, which connect to the lower groove at the top of the lower seat 1, and sliding rods 11 are slidably connected to the inner wall of the sliding grooves 12, allowing the sliding rods 11 to slide smoothly; furthermore, the bidirectional threaded drive assembly includes a bidirectional threaded screw 8 rotatably mounted on the bottom of the lower seat 1 platform via a mounting bracket 6, and the power input end of the bidirectional threaded screw 8 is connected to an electric motor. The power output end of 7 is convenient for driving; further, a limit sleeve 10 is fixedly installed in the middle of the bidirectional threaded screw 8, and threaded sleeves 9 are threadedly connected to the left-hand thread and right-hand thread at both ends of the bidirectional threaded screw 8. Slide rods 11 are fixedly installed on the top of the threaded sleeves 9 at both ends for convenient transmission; further, a first magnetic frame 16 is fixedly installed at the bottom of the frame 15, and a second magnetic frame 17 is fixedly installed at the inner edge of the lower groove in the middle of the top of the lower seat 1. The magnetic poles of the first magnetic frame 16 are opposite to those of the second magnetic frame 17, so that the lower mold 18 can be magnetically attracted.

[0022] In this solution, during use, the quick-release mold frame disclosed in this utility model is embedded in the lower groove through a magnetic suction component, and is limited by the top bar 13 driven by the bidirectional thread drive component, which facilitates the automatic and quick disassembly of the lower mold 18. The mold frame can be adapted to different lower molds 18 and can be recycled. When the lower mold 18 needs to be replaced, the external power supply turns on the motor 7 through an external switch and controls the motor 7 to rotate forward. The motor 7 drives the bidirectional threaded screw 8 to rotate clockwise. Since the left-hand thread and right-hand thread at both ends of the bidirectional threaded screw 8 are threaded with threaded sleeves 9, the top bar 13 at the top of the sliding top is driven to slide out from the top grooves 14 at both ends through the threaded sleeves 9 and the sliding rod 11, so that the old lower mold 18 can be taken out and the new lower mold 18 can be placed into the lower groove, so that the top groove 14 in the middle of the top of the frame 15 of the new lower mold 18 is in the upper groove. Align with the top bar 13. At this time, since the bottom of the frame 15 of the new lower mold 18 is fixedly installed with the first magnetic frame 16, and the inner edge of the lower groove in the middle of the top of the lower seat 1 is fixedly installed with the second magnetic frame 17, the magnetic poles of the first magnetic frame 16 are opposite to those of the second magnetic frame 17. The new lower mold 18 can be magnetically attracted into the lower groove. The external power supply controls the motor 7 to reverse through the external switch, so that the top bars 13 at both ends are simultaneously inserted into the top grooves 14 at both ends, limiting the new lower mold 18 and preventing the new lower mold 18 from moving up and down. Different lower molds 18 can be quickly replaced without manual release of the self-locking. Only the old lower mold 18 needs to be removed manually and the new lower mold 18 needs to be placed into the lower groove, simplifying the operation steps and saving replacement time (the motor 7 is a forward and reverse motor 7, and the electric telescopic rod 4 and the motor 7 are both existing products on the market).
