[0027] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, a quick-demolding handicraft mold includes a handicraft mold body 1, two first mounting seats 2 and two second mounting seats 3 are respectively installed on the upper side of the handicraft mold body 1, and the upper sides of the two first mounting seats 2 and the second mounting seats 3 are clamped with positioning plates 7, the upper sides of the four positioning plates 7 are fixedly connected to the lower mold 8, and one side of the two first mounting seats 2 and the second mounting seats 3 is slidably connected to a positioning round rod 4 for limiting the positioning plates 7;

[0029] A first spring 6 is connected between the two positioning round rods 4 and the first mounting seat 2, and a first spring 6 is connected between the two positioning round rods 4 and the second mounting seat 3. One side of the two first mounting seats 2 and the second mounting seat 3 is slidably connected with a limiting plug 9 for limiting the positioning plate 7. Through the installation and use of the positioning round rods 4 and the limiting plug 9, the positioning plate 7 can be firmly positioned between the first mounting seat 2 and the second mounting seat 3 so as to be clamped and fixed to the lower mold 8. This makes it easy to load and unload the lower mold 8, saves replacement time, and is easy to use. Two symmetrically arranged U-shaped frames 18 are installed on the upper side of the handicraft mold body 1, and the interiors of the two U-shaped frames 18 are rotatably connected with double-headed screws 19.

[0030] The outer surfaces of the two double-ended screw rods 19 are threadedly connected to two symmetrically arranged L-shaped clamping plates 22, and the interior of the two U-shaped frames 18 are connected to two limit rods 20. Through the setting of the limit rods 20, the two limit rods 20 can limit the moving trajectory of the two L-shaped clamping plates 22, so that the two L-shaped clamping plates 22 can move back and forth smoothly to strengthen the installation of the lower mold 8. The outer surfaces of the two limit rods 20 are slidably connected to the interior of the L-shaped clamping plates 22. Both ends of the double-ended screw rods 19 pass through the U-shaped frame 18 and extend to the two ends of the U-shaped frame 18. Both ends of the two double-ended screw rods 19 are fixedly connected to handwheels 21.

[0031] The lower end of the lower mold 8 is slidably connected to the demoulding telescopic plate 23, and the lower side of the demoulding telescopic plate 23 passes through the lower mold 8 and extends to the lower side of the lower mold 8. The lower side of the demoulding telescopic plate 23 is connected to a U-shaped seat 24, and a third spring 26 is connected between the U-shaped seat 24 and the lower mold 8. The inner rotation of the U-shaped seat 24 is connected to a roller 25. The upper side of the handicraft mold body 1 is fixedly provided with two symmetrically arranged fixed plates 27. The inner sides of the two fixed plates 27 are rotatably connected to a cam rotating rod 28. Through the installation and use of the cam rotating rod 28 and the roller 25, the cam rotating rod 28 is always in contact with the roller 25. When the top end of the cam rotating rod 28 lifts the roller 25, the demoulding telescopic plate 23 is allowed to perform demoulding work, which is convenient to use. The rear side of the cam rotating rod 28 passes through the fixed plate 27 and extends to the rear side of the fixed plate 27. The rear side of the cam rotating rod 28 is fixedly connected to the servo motor 29 through the motor mounting plate. The cam rotating rod 28 is located below the roller 25.

[0032] Four guide columns 12 are respectively installed on the upper side of the lower mold 8, and a top plate 13 is fixedly installed on the upper side of the four guide columns 12. A hydraulic cylinder 14 is fixedly provided inside the top plate 13, and a top seat 16 is installed on the lower side of the hydraulic cylinder 14. An upper mold 17 is fixed on the lower side of the top seat 16. Through the setting of the guide columns 12, the four guide columns 12 can be used to limit the lifting and lowering of the upper mold 17, so that the molding work of the handicraft is more stable and reliable. Four second springs 15 are installed between the lower mold 8 and the top seat 16. Through the setting of the second springs 15, the elastic force of the second springs 15 can be used to reduce the impact force when the upper mold 17 descends, so as to protect the mold and extend the service life of the handicraft mold.

[0033] One side of the positioning rod 4 passes through the first mounting seat 2 and the second mounting seat 3 and extends to the other side of the first mounting seat 2 and the second mounting seat 3. A side plate 5 is fixedly installed on one side of the two positioning rods 4. Two symmetrically arranged U-shaped plates 10 are installed on the upper side of the handicraft mold body 1. The inner sides of the two U-shaped plates 10 are rotatably connected to a movable plate 11 for fixing the side plate 5.

[0034] The inner side surfaces of the four positioning plates 7 are all provided with a card slot 99 , which is adapted to the L-shaped card plate 22 , and one side of the L-shaped card plate 22 is card-connected to the inner side surface of the positioning plate 7 through the card slot 99 .

[0035] The working principle of the quick demoulding handicraft mold provided by the utility model is as follows:

[0036] When the two side plates 5 are pulled in sequence, the two side plates 5 will drive the positioning rods 4 equipped with the first springs 6 to retract, and then the two movable plates 11 are rotated upward, so that the movable plates 11 can limit and fix the side plates 5, and then the four positioning plates 7 at the lower mold 8 are inserted into the two first mounting seats 2 and the two second mounting seats 3 for preliminary positioning of the lower mold 8, and then the limit of the two side plates 5 is released, so that the positioning rods 4 with elastic force can be inserted into the positioning plates 7, and then the handwheel 21 is turned to drive the double-headed screw rod 19 to rotate, so that the two L-shaped clamping plates 22 on the double-headed screw rod 19 can move relatively and be clamped into the clamping grooves 99 of the positioning plates 7. At this time, the four limiting plug posts 9 are inserted into the interior of the four positioning plates 7, which is conducive to further clamping and fixing the lower mold 8, ensuring the stability of the lower mold 8 when installed, so that the new lower mold 8 can be quickly and conveniently replaced by the clamping method, saving time and effort, and improving the replacement efficiency of the handicraft mold;

[0037] The molten plastic can be injected into the mold cavity by the lifting action of the lower mold 8 and the upper mold 17, and the molding of the handicraft is completed by the opening and closing action. Then the hydraulic cylinder 14 drives the upper mold 17 to move upward, and then the output shaft of the servo motor 29 drives the rotation of the cam rod 28 to squeeze the roller 25 at the U-shaped seat 24. As the cam rod 28 rotates, the U-shaped seat 24 equipped with the third spring 26 is gradually lifted and moved upward, so as to drive the demoulding telescopic plate 23 to move upward and lift the handicraft in the lower mold 8, thereby realizing rapid demoulding. At the same time, the demoulding telescopic plate 23 with elastic force can weaken the demoulding force, which is used to protect the demoulded handicraft and ensure the processing quality of the handicraft mold.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
