[0002] Plastic bottle molding dies are a key step in plastic blow molding or injection molding processes, and their design, manufacturing, and use directly affect the quality and production efficiency of plastic bottles.

[0003] Currently, in enterprise production, companies develop new bottle types (such as adjusting bottle shape, thread structure, and embossed patterns), make functional improvements (such as adding anti-slip textures and improving cap sealing), and produce plastic bottles of different volumes as needed. All of these improvements require new injection molds to enable the production of different plastic bottles. In existing technology, the plastic bottle molding mold and extrusion equipment are connected by bolts. When replacing the molding mold, multiple bolts need to be tightened or loosened one by one, which is time-consuming and labor-intensive (usually taking 30 minutes to 2 hours), thereby increasing downtime and reducing the overall production capacity of plastic bottles. Utility Model Content

A U-shaped plate is fixedly installed at the power output end of the hydraulic cylinder, and an installation plate is fixedly installed on one side of the forming mold. The bottom of the installation plate has a fixing groove that matches the U-shaped plate.

[0007] As a further description of the above technical solution: The positioning plate is set as an L-shaped structure, and the end of the positioning plate away from the second forming mold points to the bottom of the second forming mold. A limit block is fixedly installed on one side of the inner cavity of the receiving groove, and an elastic plate for limiting the positioning plate is fixedly installed on one end of the limit block.

[0008] As a further description of the above technical solution: Multiple upright plates are fixedly installed with bearing blocks on one side of the forming mold 2, and multiple support blocks are fixedly installed on one side of the forming mold 2. The top of each bearing block is provided with a groove that matches the support block.

[0009] As a further description of the above technical solution: Multiple positioning posts are fixedly installed on the inner wall of the fixed groove away from its own opening end. Multiple positioning holes that match the positioning posts are opened at one end of the U-shaped plate.

[0014] 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.

[0015] Reference Figure 1-5 One embodiment of this utility model provides: a plastic bottle forming mold, comprising: The base plate 1 has a detachable top mounting of a first molding die 9 and a second molding die 10. When the first molding die 9 and the second molding die 10 are closed, molten plastic granules are injected into the cavity between the first molding die 9 and the second molding die 10. After the plastic is formed, the plastic bottle can be formed by rapidly cooling the formed plastic (this is existing technology and will not be described in detail here).

[0016] Multiple upright plates 5 are fixedly installed on the top of the base plate 1, and multiple positioning plates 12 are fixedly installed on one side of the forming mold 2 10. The positioning plates 12 are set in an L-shaped structure, and the end of the positioning plate 12 away from the forming mold 2 10 points to the bottom of the forming mold 2 10. The top of the multiple upright plates 5 is provided with receiving grooves that are adapted to the positioning plates 12. When installing the forming mold 2 10, the ends of the multiple positioning plates 12 installed on one side away from the forming mold 2 10 are simultaneously inserted into the inner cavities of the multiple receiving grooves. When the inserted end of the positioning plate 12 is in contact with the inner wall of the receiving groove away from its own opening end, the side wall of the positioning plate 12 is in contact with the top of the upright plate 5, thereby achieving the support and limiting of the forming mold 2 10.

[0017] When the insertion end of the positioning plate 12 is in contact with the inner wall of the receiving groove away from its own opening end, the straight distance between the two sides of the positioning plate 12 and the inner wall of the receiving groove is no more than 1 mm, which prevents the positioning plate 12 from wobbling left and right in the inner cavity of the receiving groove and improves the stability of the positioning plate 12.

[0018] A limiting block 16 is fixedly installed on one side of the inner cavity of the receiving groove. An elastic plate 14 for limiting the positioning plate 12 is fixedly installed on one end of the limiting block 16. When the insertion end of the positioning plate 12 is inserted into the inner cavity of the receiving groove, one side of the positioning plate 12 is in contact with the bent end of the elastic plate 14, causing the bent end of the elastic plate 14 to deform. At this time, the elastic plate 14 applies a pushing force to the outer wall of the positioning plate 12, so that the side of the positioning plate 12 away from the elastic plate 14 is in contact with the inner wall of the receiving groove, preventing the positioning plate 12 from wobbling back and forth in the inner cavity of the receiving groove, thus improving the stability of the molding die 2 10 during injection molding.

[0019] Multiple upright plates 5 are fixedly installed with bearing blocks 4 on one side near the molding mold 2 10. Multiple support blocks 13 are fixedly installed on one side of the molding mold 2 10. The top of each of the multiple bearing blocks 4 is provided with a groove that matches the support block 13. When the insertion end of the positioning plate 12 is in contact with the inner wall of the receiving groove away from its own opening end, the bottom of the multiple bearing blocks 4 is simultaneously in contact with the bottom of the inner cavity of the multiple grooves. The multiple bearing blocks 4 can support the molding mold 2 10, further improving the stability of the molding mold 2 10.

[0020] When the elastic plate 14 is deformed by the pressure of the positioning plate 12, it stores its own elastic potential energy. When the elastic plate 14 is pulled out from the inner cavity of the receiving groove, the elastic plate 14 can quickly return to its original position. At the same time, the elastic plate 14 is made of stainless steel spring sheet, which can increase the strength of the elastic plate 14 and extend the service life of the elastic plate 14.

[0021] A hydraulic cylinder for reciprocating movement of the forming mold 9 is fixedly installed on the top of the base plate 1. A U-shaped plate 2 is fixedly installed on the power output end of the hydraulic cylinder. An mounting plate 8 is fixedly installed on one side of the forming mold 9. A fixing groove adapted to the U-shaped plate 2 is opened at the bottom of the mounting plate 8. The power output end of the hydraulic cylinder is fixedly connected to one side of the U-shaped plate 2. When installing the forming mold 9, the mounting plate 8 is placed directly above the U-shaped plate 2, and then the forming mold 9 is slowly lowered until the top end of the U-shaped plate 2 is inserted into the inner cavity of the fixing groove, thus achieving the initial connection between the forming mold 9 and the power output end of the hydraulic cylinder.

[0022] Multiple positioning posts 3 are fixedly installed on the inner wall of the fixed groove away from its own opening. One end of the U-shaped plate 2 has multiple positioning holes that are compatible with the positioning posts 3. When the top end of the U-shaped plate 2 is attached to the inner wall of the fixed groove away from its own opening, the multiple positioning posts 3 are simultaneously inserted into the inner cavity of the multiple positioning holes. This achieves the connection between the U-shaped plate 2 and the mounting plate 8, while preventing the mounting plate 8 from wobbling left or right or back and forth, thus improving the stability of the forming mold 9.

[0023] Multiple extrusion plates 15 are fixedly installed on one side of the inner cavity of the fixed groove to press against the outer wall of the U-shaped plate 2. One end of the extrusion plate 15 is bent. When the top end of the U-shaped plate 2 is inserted into the inner cavity of the fixed groove, the bent end of the extrusion plate 15 deforms, thereby increasing the friction between the U-shaped plate 2 and the inner wall of the fixed groove. This prevents the forming mold 9 from swaying up and down when it moves back and forth with the power output end of the hydraulic cylinder, thus improving the stability of the forming mold 9.

[0024] Two positioning rings 6 are fixedly installed on the top of the base plate 1. The first molding die 9 and the second molding die 10 are located between the two positioning rings 6. A guide rod 7 is slidably connected between the two positioning rings 6. A connecting plate connected to the top of the base plate 1 is fixedly installed at the bottom of each of the two positioning rings 6. At the same time, both positioning rings 6 are located above the first molding die 9.

[0025] One end of one of the positioning rings 6 is fixedly installed with an electromagnet ring for fixing the guide rod 7. The guide rod 7 is set as a T-shaped structure. After the molding mold 1 9 and the molding mold 2 10 are installed, the small end of the guide rod 7 is inserted into the interior of the other positioning ring 6 from the inner cavity of one of the positioning rings 6 until the large end of the guide rod 7 is in contact with one end of the electromagnet ring. Then, the electromagnet ring is energized, and the large end of the guide rod 7 can be fixed by the electromagnet ring.

[0026] Two guide rings 11 are slidably sleeved on the outer wall of the guide rod 7. The two guide rings 11 are fixedly connected to the top of the first molding die 9 and the second molding die 10, respectively. When the small end of the guide rod 7 is inserted into the interior of the other positioning ring 6 from the inner cavity of one positioning ring 6, both guide rings 11 are slidably sleeved on the outside of the guide rod 7. At the same time, the inner walls of the two guide rings 11 are in contact with the outer wall of the guide rod 7. Through the cooperation of the guide rod 7 and the guide rings 11, the first molding die 9 and the second molding die 10 can be limited to prevent the first molding die 9 and the second molding die 10 from shaking up and down.

[0027] When the forming mold 9 moves back and forth with the power output end of the hydraulic cylinder, the sliding trajectory of the forming mold 9 can be limited by the cooperation of the guide ring 11 and the guide rod 7, so as to prevent the forming mold 9 from wobbling left and right or up and down when it moves back and forth, thus improving the accuracy of the back and forth movement of the forming mold 9.

[0028] When it is necessary to replace molding mold 1 9 and molding mold 2 10, the electromagnet ring is de-energized, and then the guide rod 7 is pulled out from inside the two positioning rings 6, thereby releasing the restriction on the top of molding mold 1 9 and molding mold 2 10. Then, the top of the U-shaped plate 2 is pulled out from inside the fixing groove, and then one end of the positioning plate 12 is pulled out from inside the receiving groove to remove molding mold 1 9 and molding mold 2 10. This reduces the time and effort required for replacing plastic bottle injection molds and the downtime, and improves the overall production capacity of plastic bottles.

[0029] The U-shaped plate 2, mounting plate 8, positioning plate 12, upright plate 5, and guide rod 7 constitute the disassembly and assembly parts. The disassembly and assembly parts can realize the mutual disassembly and assembly of the molding mold 19 and the power output end of the hydraulic cylinder, and realize the disassembly and assembly of the top of the molding mold 20 and the base plate 1, as well as increase the stability of the movement of the molding mold 19, reduce the time and effort required for changing the plastic bottle injection mold and the downtime, and improve the overall production capacity of plastic bottles.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
