During the production process of plastic cosmetic bottles, in order to enable plastic cosmetic bottles to form various different shapes and sizes according to requirements, a forming mold is needed. During the forming process of a plastic cosmetic bottle, the plastic blank is first heated, and then the heated plastic blank is subjected to a blow molding operation to make it expand and form according to a predetermined shape; in order to ensure the smooth demolding of the formed cosmetic bottle, it is necessary to lower the temperature of the formed cosmetic bottle, because at a high temperature, the adhesion between the plastic and the mold is large, which will increase the difficulty of demolding and may even cause deformation or damage to the cosmetic bottle. However, the traditional forming mold does not have an additional cooling structure, and only relies on the heat dissipation of the mold itself and natural cooling, resulting in a weak heat dissipation effect, thus reducing the production efficiency; at the same time, temperature unevenness is also likely to occur during the cooling process, resulting in inconsistent shrinkage of each part of the cosmetic bottle, reducing the dimensional accuracy and quality stability of the product.

[0021] The following further describes in detail the implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the technical solutions of the present utility model, but cannot be used to limit the protection scope of the present utility model.

[0022] Embodiment:

[0023] As Figures 1 to 4 shown, the present utility model provides a plastic cosmetic bottle forming mold, which includes two sets of forming templates 11, and the two sets of forming templates 11 are distributed in a corresponding manner. A forming groove 12 is formed on the forming template 11. When one side of the two sets of forming templates 11 comes into contact with each other, a forming cavity will be jointly formed between the two forming grooves 12. This forming cavity is the key to shaping the plastic cosmetic bottle with its shape and size. In addition, a placement groove 13 is formed on the forming template 11 to facilitate the placement of the plastic embryo body. A base 21 is provided on one side of each of the two sets of forming templates 11, and a heat conducting plate 22 and a fixing plate 23 are provided between the base 21 and the forming template 11. Among them, the heat conducting plate 22 is in direct contact with the forming template 11 to play an effective heat conducting role during the forming process of the plastic cosmetic bottle. When a large amount of heat is inevitably generated during the forming process of the plastic cosmetic bottle, the heat conducting plate 22 can sense and absorb this heat, so that the heat can be transferred from the forming template 11 to the heat conducting plate 22. At the same time, a cooling pipe 24 is provided between the heat conducting plate 22 and the fixing plate 23, and both ends of the cooling pipe 24 are connected to an external cooling system. When the heat is absorbed by the heat conducting plate 22, the coolant in the external cooling system will flow through the cooling pipe 24. The flow of the coolant quickly takes away the heat on the heat conducting plate 22, enabling the entire mold to achieve a large temperature drop in a short time. This not only provides a reliable guarantee for the continuous and stable operation of the mold, but also ensures the temperature uniformity during the forming process. Thus, it effectively avoids the quality problems of the plastic cosmetic bottle caused by uneven temperature, and improves the product qualification rate and production efficiency.

[0024] As Figure 2 、 Figure 3As shown, the forming template 11 is composed of an outer frame 31 and a mold core 32. The mold core 32 is clamped inside the outer frame 31. A plurality of groups of connecting holes 33 are opened on both the outer frame 31 and the mold core 32. The connecting bolts 34 are firmly clamped in the connecting holes 33, so that the outer frame 31 and the mold core 32 are detachably connected. The forming groove 12 is located on the mold core 32. The detachable connection enables that when it is necessary to adjust or replace the forming shape, only the mold core 32 needs to be operated. The direct contact between the heat conducting plate 22 and the mold core 32 ensures that the heat generated during the forming process can be quickly and effectively transferred to the heat conducting plate 22, and then taken away by the cooling system, ensuring the temperature stability during the forming process. Both groups of forming templates 11 are connected to the external opening and closing structure, enabling the opening and closing operation between the two groups of forming templates 11, which is convenient for taking the finished product. On both sides of one group of the base 21, a plurality of groups of guide rods 25 are provided. On both sides of the corresponding one group of the outer frame 31, guide plates 26 are provided. Guide holes 27 corresponding to the guide rods 25 are opened on the guide plates 26, so that the guide rods 25 can pass through the guide holes 27. During the opening and closing process of the mold, the cooperation between the guide rods 25 and the guide holes 27 can ensure that the moving paths of the two groups of forming templates 11 are accurate, avoiding the forming errors or mold damage that may be caused by the moving deviation. Whether it is frequent opening and closing operations or long-term continuous production, the guiding structure can ensure the stability and accuracy of the mold operation. In addition, a plurality of groups of positioning columns 28 are provided on one side of the base 21. Positioning holes 29 are opened on the fixing plate 23, the heat conducting plate 22 and the forming template 11. The positioning columns 28 can pass through the positioning holes 29. Effectively preventing the position deviation of each component during the installation and use process, ensuring the stability and reliability of the overall structure of the mold.

[0025] A plurality of groups of mounting holes 41 are opened on the base 21, the fixing plate 23, the heat conducting plate 22 and the forming template 11. At the same time, a plurality of groups of mounting bolts 42 are provided on one side of the base 21. The mounting bolts 42 can pass through the corresponding mounting holes 41, realizing a detachable connection method between the base 21, the fixing plate 23, the heat conducting plate 22 and the forming template 11. When a certain component of the mold is damaged or needs maintenance, it can be conveniently disassembled for separate treatment without the need to disassemble the entire mold on a large scale, greatly improving the maintenance efficiency and reducing the maintenance cost.

[0026] As Figure 2 , Figure 4As shown, fixing grooves 43 are formed between the fixing plate 23 and the heat conducting plate 22. The cooling pipe 24 can be clamped in the fixing groove 43, ensuring the position stability of the cooling pipe 24 during operation, preventing it from shifting due to vibration or other external factors, and thus ensuring the stability and reliability of the cooling effect. In addition, a plurality of limiting grooves 44 are formed on the fixing plate 23, and corresponding limiting blocks 45 are provided on the heat conducting plate 22. The limiting blocks 45 can be clamped in the limiting grooves 44. This not only further enhances the connection stability between the fixing plate 23 and the heat conducting plate 22, but also plays a role in rapid positioning during the assembly of the mold, ensuring that the two can be accurately assembled together. At the same time, during the operation of the mold, the possible lateral movement or rotation of the heat conducting plate 22 is effectively restricted.

[0027] When the two sets of forming templates 11 come into contact with each other, a placement hole 14 is formed between the two sets of placement grooves 13. During production, the plastic embryo body will be inserted through this placement hole 14, and one end of it is located in the forming cavity, ensuring the position stability of the plastic embryo body during the forming process and providing a strong guarantee for producing plastic cosmetic bottles with accurate shapes and high dimensional accuracy.

[0028] The specific usage mode and function of this embodiment:

[0029] During use, according to the shape and size of the plastic cosmetic bottle to be produced, a suitable mold core 32 is selected and installed in the outer frame 31 through the connecting bolts 34. The heat conducting plate 22 and the fixing plate 23 are correctly installed on the base 21, ensuring that the cooling pipe 24 is clamped in the fixing groove 43, the limiting block 45 is clamped in the limiting groove 44, and the positioning post 28 is inserted through the corresponding positioning hole 29. Then, the assembled components such as the base 21, the heat conducting plate 22, and the fixing plate 23 are connected and fixed to the forming template 11 through the mounting bolts 42 and the mounting holes 41. During production, the plastic embryo body is inserted through the placement hole 14 so that one end is accurately located in the forming cavity. The external opening and closing structure is activated to make the two sets of forming templates 11 close tightly. During the forming process of the plastic cosmetic bottle, the heat generated in the mold will be quickly absorbed by the heat conducting plate 22 and taken away by the coolant flowing in the cooling pipe 24, ensuring that the mold temperature is uniform and rapidly reduced. After forming, the two sets of forming templates 11 are opened through the opening and closing structure, and the formed plastic cosmetic bottle can be conveniently taken out.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
