[0018] 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. Example 1

[0019] like Figure 1-2As shown, the technical solution adopted by this utility model is as follows: A molding die for manufacturing plastic flowers. It includes a base 1. A support plate 2 is fixedly installed on the base 1. A connecting plate 4 is vertically slidably installed on the support plate 2. An upper mold 5 is fixedly installed on the connecting plate 4.

[0020] Specifically, the connecting plate 4 includes two vertical rods and one horizontal rod. The two vertical rods are respectively fixed to both ends of the horizontal rod. The upper mold 5 and the output end of the cylinder 3 are fixed to the horizontal rod. A lower mold 8 is fixedly installed on the base 1, and the lower mold 8 is located directly below the upper mold 5.

[0021] A cylinder 3 is fixedly mounted on the upper end of the support plate 2. The output end of the cylinder 3 passes downward through the support plate 2 and is located below the support plate 2. The output shaft of the cylinder 3 is slidably connected to the support plate 2. The output shaft of the cylinder 3 is fixedly connected to the crossbar of the connecting plate 4.

[0022] Start cylinder 3, which pushes connecting plate 4 and upper mold 5 to move up and down together, thus realizing the stamping operation.

[0023] An ejection mechanism is vertically slidably installed inside the lower mold 8. The ejection mechanism includes an ejector block 12, which is vertically slidably connected to the lower mold 8. When the ejector block 12 is at its lowest displacement position, it is flush with the bottom surface of the die cavity of the lower mold 8. After stamping is completed, the ejector block 12 moves upward to eject the stamped plastic flower.

[0024] A drive mechanism for driving the ejector mechanism to move upward is installed between the connecting plate 4 and the ejector mechanism. Furthermore, two drive mechanisms are provided, arranged symmetrically. Specifically, the drive mechanism is installed between the vertical rod of the connecting plate 4 and the top block 12.

[0025] The driving mechanism includes: a hinge plate 6, a first spring 7, a limiting rod 9, a lifting plate 10, and a sliding rod 11.

[0026] Wherein: the hinge plate 6 is installed on the vertical rod of the connecting plate 4 near the lower part. The hinge plate 6 is rotatably connected to the vertical rod of the connecting plate 4.

[0027] Specifically, the hinge plate 6 includes a horizontal plate and two inclined plates. The two inclined plates are fixed to the horizontal plate near the center of the horizontal plate. The two inclined plates are arranged in parallel. A clearance groove is formed between the two inclined plates. The end of the inclined plate away from the connecting plate 4 is higher than the end of the inclined plate near the connecting plate 4.

[0028] The first spring 7 is fixedly installed between the vertical rod of the connecting plate 4 and the hinge plate 6. Two first springs 7 are provided. The two first springs 7 correspond to the two inclined plates respectively. One end of the first spring 7 is fixed to the connecting plate 4, and the other end of the first spring 7 is fixed to the corresponding inclined plate of the hinge plate 6. The fixed position of the first spring 7 and the connecting plate 4 is located on the upper surface of the inclined plate of the hinge plate 6, so that the first spring 7 is in an inclined state.

[0029] The lower mold 8 has an installation groove, and the limiting rod 9 is fixed in the installation groove of the lower mold 8. The axis of the limiting rod 9 is set in the vertical direction. The limiting rod 9 is set as a spring telescopic rod.

[0030] The lifting plate 10 is located between the limiting rod 9 and the top block 12. The upper end face of the lifting plate 10 is fixedly connected to the top block 12. The lower end face of the lifting plate 10 is fixedly connected to the telescopic end of the limiting rod 9.

[0031] The slide rod 11 cooperates with the hinge plate 6. Specifically, the slide rod 11 is fixedly installed at the end of the lifting plate 10 and located outside the lower mold 8. The slide rod 11 includes an inclined rod and a cylindrical rod. The inclined rod is inclined outward and downward, and the cylindrical rod is fixed at the end of the inclined rod away from the lifting plate 10.

[0032] The specific usage method of this application is as follows: Initially, the limiting rod 9 positions the top block 12 at its lowest displacement position. The top block 12 is flush with the bottom surface of the lower mold 8.

[0033] The raw material is placed in the lower mold 8. The cylinder 3 is activated, causing the connecting plate 4 and the upper mold 5 to move downwards. The connecting plate 4 then moves the hinge plate 6 downwards. The upper mold 5 moves downwards and comes into contact with the raw material. The upper mold 5 and the lower mold 8 cooperate to stamp the raw material.

[0034] When the connecting plate 4 moves the hinge plate 6 downwards until the horizontal plate of the hinge plate 6 contacts the cylindrical rod of the slide rod 11, the slide rod 11 blocks the hinge plate 6. As the connecting plate 4 continues to move the hinge plate 6 downwards, the slide rod 11 pushes the hinge plate 6 to rotate, and the first spring 7 is compressed and deformed. That is, the hinge plate 6 rotates upwards, increasing the horizontal distance between the hinge plate 6 and the slide rod 11. As the connecting plate 4 continues to move downwards, the hinge plate 6 gradually disengages from the slide rod 11. After the horizontal plate of the hinge plate 6 disengages from the slide rod 11, under the elastic force of the first spring 7, the hinge plate 6 rotates downwards in the opposite direction to reset its position. This places the horizontal plate of the hinge plate 6 below the slide rod 11.

[0035] After stamping is complete, the connecting plate 4 drives the hinge plate 6 to move upward. Since the horizontal bar of the hinge plate 6 is below the slide bar 11, the hinge plate 6 will drive the slide bar 11 to move upward. When the slide bar 11 moves upward, it drives the top block 12 to move upward via the lifting plate 10. The upward movement of the top block 12 pushes out the stamped plastic flower. When the top block 12 moves upward, the limiting rod 9 extends.

[0036] After the top block 12 moves upward to its uppermost displacement position, the connecting plate 4 drives the hinge plate 6 to continue moving upward. The slide rod 11 will block the hinge plate 6. During the upward movement of the connecting plate 4, the hinge plate 6 will rotate downward, increasing the horizontal distance between the hinge plate 6 and the slide rod 11. During this process, the first spring 7 gradually extends. When the horizontal plate of the hinge plate 6 disengages from the slide rod 11, under the elastic force of the first spring 7, the hinge plate 6 rotates upward in the opposite direction to reset. This places the horizontal plate of the hinge plate 6 above the slide rod 11. Example 2

[0037] This embodiment is based on Embodiment 1, and provides a different driving mechanism to realize the function of driving the top block 12 to be pushed out.

[0038] In this embodiment, please refer to Figures 3-4 The driving mechanism includes: a sloping plate 13, a sliding member 15, a first sloping block 16, a second spring 17, and a second sloping block 18.

[0039] The inclined plate 13 is rotatably connected to the connecting plate 4. A torsion spring is installed between the inclined plate 13 and the connecting plate 4. The end of the inclined plate 13 away from the connecting plate 4 is set as an inclined surface. The inclined surface of the inclined plate 13 makes its longitudinal section trapezoidal, and the length of the upper base of the trapezoid is shorter than the length of the lower base. A baffle 14 is fixedly installed on the connecting plate 4. The baffle 14 is located below the inclined plate 13. The baffle 14 limits the inclined plate 13, so that the inclined plate 13 can only rotate above the baffle 14.

[0040] The lower mold 8 has an installation groove. The second inclined block 18 is located in the installation groove. The second inclined block 18 is fixedly connected to the top block 12. The second inclined block 18 is configured as an inverted isosceles trapezoidal block.

[0041] The first inclined block 16 is horizontally slidably installed in the mounting groove of the lower mold 8. The first inclined block 16 has an inclined surface near the second inclined block 18 that fits against the inclined surface of the isosceles trapezoidal block of the second inclined block 18. The second spring 17 is fixed between the side wall of the mounting groove and the first inclined block 16.

[0042] The sliding member 15 is horizontally positioned. The sliding member 15 is fixedly connected to the first inclined block 16 and located outside the lower mold 8. The end of the sliding member 15 is cylindrical. The cylindrical surface of the sliding member 15 engages with the inclined surface of the inclined plate 13.

[0043] When the connecting plate 4 moves the inclined plate 13 downwards, causing it to contact the cylindrical surface of the sliding member 15, the sliding member 15 blocks the inclined plate 13. As the connecting plate 4 continues to move the inclined plate 13 downwards, the sliding member 15 pushes the inclined plate 13 to rotate. That is, the inclined plate 13 rotates upwards, increasing the horizontal distance between the inclined plate 13 and the sliding member 15. As the connecting plate 4 continues to move downwards, the inclined plate 13 gradually disengages from the sliding member 15. After the horizontal plate of the inclined plate 13 disengages from the sliding member 15, under the torsion of the torsion spring, the inclined plate 13 rotates downwards to reset, placing the inclined plate 13 below the sliding member 15.

[0044] After stamping is completed, the connecting plate 4 drives the inclined plate 13 to move upward. Since the inclined plate 13 is located below the sliding member 15, the inclined surface of the inclined plate 13 pushes the sliding member 15 to move closer to the axis of the lower mold 8. The sliding member 15 pushes the first inclined block 16 to move closer to the axis of the lower mold 8. Under the action of the inclined surfaces of the first inclined block 16 and the second inclined block 18, the first inclined block 16 pushes the second inclined block 18 and the top block 12 to move upward. The top block 12 moves upward to eject the stamped plastic flower. When the first inclined block 16 moves closer to the axis of the lower mold 8, the second spring 17 extends. When the top block 12 moves upward to the uppermost position of its displacement position, the sliding member 15 moves to a position where it is disengaged from the inclined plate 13. The connecting plate 4 drives the inclined plate 13 to continue moving upward, and the sliding member 15 and the first inclined block 16 move away from the axis of the lower mold 8 and reset under the action of the second spring 17. At the same time, the second inclined block 18 and the top block 12 move downward and reset under their own gravity.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
