[0021] 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.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] The components of this application, such as the upper mold 1, lower mold 2, support platform 3, column 4, guide rod 5, top plate 6, cylinder 7, support block 8, limit stop frame 9, reinforcing plate 10, limit stop 11, stepper motor 12, screw 13, adjusting plate 14, guide slide rod 15, gear plate 16, circular gear 17, fixing plate 18, and support shaft 19, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0024] Example 1:

[0025] Please see Figures 1-5 As shown, this utility model provides a thermoforming mobile phone case mold, comprising:

[0026] The lower mold 2 has guide rods 5 movably connected to both ends of the top of the lower mold 2 via bearings. A limit baffle 11 is fixedly connected to the upper end of the back of the guide rod 5. A circular gear 17 is fixedly installed at the bottom of the guide rod 5. A stepper motor 12 is fixedly installed in the middle of the inner cavity of the lower mold 2. A screw 13 is fixedly installed at the output end of the stepper motor 12. An adjusting plate 14 is threadedly connected to the surface of the screw 13. Toothed plates 16 are fixedly installed on both sides of the adjusting plate 14. The toothed plates 16 mesh with the circular gear 17.

[0027] The upper mold 1 is slidably connected to the upper end of the guide rod 5 and located below the limit baffle 11. A cylinder 7 is fixedly installed at the middle of the top of the upper mold 1, and limit baffle frames 9 are fixedly connected to both ends of the top of the upper mold 1.

[0028] In this technical solution, the thermoforming material required for mobile phone case production is placed on the top of the lower mold 2. After being heated and softened by external heating equipment, the upper mold 1 is moved downward by extending the cylinder 7, while pressure is applied to the material so that it can be formed between the upper mold 1 and the lower mold 2. After the mobile phone case is formed, the upper mold 1 is moved upward by retracting the cylinder 7. At the same time, the stepper motor 12 is started to drive the screw 13 to rotate. The rotation of the screw 13 drives the adjusting plate 14 and the toothed plate 16 to move forward. The movement of the toothed plate 16 drives the two sets of circular gears 17, the guide rod 5 and the limiting baffle 11 to rotate. Under the action of rotation, the limiting baffle 11 can be inserted into the limiting frame 9. This can limit the vertical direction of the upper mold 1 to a certain extent when the personnel are picking up the material. This reduces the probability of the cylinder 7 pushing the upper mold 1 to fall rapidly due to misoperation or malfunction, and causing crush injuries to the personnel's hands, thus improving the safety of personnel operation.

[0029] It should be noted that, as existing technology, cylinder 7 is operated by an external directional control valve, which is connected to an external air pump supply line to enable cylinder 7 to operate normally.

[0030] Example 2:

[0031] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a support platform 3 is fixedly installed at the bottom of the lower mold 2. Columns 4 are fixedly connected to the top of the support platform 3 around its perimeter. A top plate 6 is fixedly connected between the tops of the four columns 4. The surface of the cylinder 7 is fixedly installed at the middle of the top plate 6. The top of the guide rod 5 is movably connected to the bottom of the top plate 6 via a bearing. Support blocks 8 are fixedly connected to the bottom of the support platform 3 around its perimeter. A load-bearing base plate is fixedly connected between the bottoms of two support blocks 8. Fixed plates 18 are fixedly connected to the lower ends of both sides of the inner cavity of the lower mold 2. A support shaft 19 is fixedly installed at the middle of the bottom of the circular gear 17. The bottom of the support shaft 19 is movably connected to the top of the fixed plate 18 via a bearing. A guide slide rod 15 is slidably connected between the surface of the toothed plate 16 and the surface of the adjusting plate 14. The two sides of the guide slide rod 15 are fixedly connected to the inner cavity of the lower mold 2. A reinforcing plate 10 is fixedly connected between the top of the limiting baffle 11 and the upper end of the back of the guide rod 5. The front surface of the screw 13 is movably connected to the inner cavity of the lower mold 2 via a bearing.

[0032] In this technical solution, the support platform 3, column 4, top plate 6, support block 8 and load-bearing base plate are used to support the whole structure. The fixed plate 18 and support shaft 19 are used to support the bottom of the circular gear 17 and prevent the circular gear 17 from shifting due to force. The guide slide rod 15 is used to guide the toothed plate 16 and the adjusting plate 14 and prevent the toothed plate 16 and the adjusting plate 14 from rotating or tilting during movement. The reinforcing plate 10 is used to effectively improve the strength of the connection between the limiting baffle 11 and the guide rod 5.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
