Technical Field
[0001] This utility model relates to the field of plastic container manufacturing technology, and more specifically, to an integrated molding mold for plastic packaging containers. Background Technology
[0002] Plastic bottles are widely used for single-use packaging of liquids or solids, such as beverages, food, pickles, honey, dried fruits, edible oils, and agricultural and veterinary drugs, due to their numerous advantages, including being unbreakable, inexpensive, highly transparent, and made from food-grade raw materials. Currently, plastic bottles are mainly produced through blow molding or injection molding processes, both of which heavily rely on molds to shape the plastic bottles.
[0003] A search revealed Chinese patent application number 201721175081.4, which discloses a plastic bottle blow molding equipment. The equipment is characterized by comprising a first mold assembly and a second mold assembly arranged opposite to each other, which can be assembled into a mold body. The mold body has a mold cavity, and fins extend outward from the outer walls of the two mold assemblies, with a heat dissipation space between each pair of adjacent fins. Multiple through holes are formed on the fins, and a heat dissipation pipe passes through these holes and coils serpentinely around the outer wall of the mold assembly. A base is placed below the mold body, and multiple air outlets are formed on the base, corresponding to the heat dissipation space. This invention uses heat dissipation pipes and fins to cool the mold, while simultaneously utilizing upward-blowing air to lower the temperature at the bottom of the mold. This increases the cooling rate of the plastic bottle after contact with the inner wall of the mold, ensuring the plastic bottle is at a low temperature after mold opening, improving the stability of the plastic, and preventing deformation of the plastic bottle due to subsequent handling and processing after mold opening. However, the aforementioned patents have the following shortcomings: during use, the heat dissipation pipes and fins are directly exposed, making them prone to deformation and leakage upon impact. Furthermore, the airflow from the exhaust vents is easily dispersed, affecting the overall heat dissipation effect. Therefore, this utility model proposes a new solution. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of the above-mentioned patent where the heat dissipation pipes and fins are directly exposed during use, making them prone to deformation and leakage when impacted, and the air blown out through the air outlet is easily dispersed, affecting the overall heat dissipation effect. Therefore, this utility model proposes an integrated molding mold for plastic packaging containers.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] One-piece molding molds for plastic packaging containers are developed to improve the above-mentioned problems.
[0007] The present invention is as follows:
[0008] The device includes a mold frame and a first mold assembly and a second mold assembly installed inside the mold frame. The outer walls of the first mold assembly and the second mold assembly are provided with fins and heat dissipation pipes that cooperate with the fins. The outer walls of the first mold assembly and the second mold assembly are detachably equipped with protective covers for protecting the fins and the heat dissipation pipes. The top and bottom of the protective cover are provided with openings. Multiple evenly distributed first bolts are threaded onto the protective cover. A dustproof assembly is detachably installed on the top of the protective cover, and a filter assembly is detachably installed on the bottom of the protective cover. An air inlet pipe with one end inserted into the inside of the filter assembly is installed on the side wall of the filter assembly.
[0009] As a preferred technical solution of this utility model, the mold frame includes a base plate, and a first mounting plate and a second mounting plate are symmetrically mounted on the top of the base plate. A through hole is provided between the first mounting plate and the second mounting plate on the base plate. A cylinder is fixedly mounted on the side wall of the first mounting plate, and a first mounting bracket for mounting the first mold assembly is fixedly mounted on the moving end of the cylinder.

[0010] As a preferred technical solution of this utility model, guide rods are fixedly connected to the four corners of the first mounting bracket, and wear-resistant sleeves that cooperate with the guide rods are installed through the four corners of the first mounting plate.
[0011] As a preferred technical solution of this utility model, the dustproof component includes a frame, on which a through groove is provided, and a dustproof net is installed on the inner side of the through groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In the solution of this utility model:
[0016] 1. By setting up the protective cover and the first bolt, the fins and heat sink can be protected and the external collision can be effectively isolated, thereby significantly reducing the risk of damage to the fins and heat sink due to collision. At the same time, the protective cover can also constrain the airflow direction inside the air during use, so that the airflow can flow along the fins, greatly reducing the loss of airflow lateral diffusion, improving the contact efficiency and heat exchange intensity between the air and the surface of the fins and heat sink, thereby improving the overall heat dissipation effect.
[0017] 2. By setting up dustproof and filter components, the dustproof components can prevent dust from the environment from directly entering the protective cover during use, and the filter components can filter the air delivered into the air intake pipe, reducing the accumulation of dust and other pollutants in the gaps between the fins and on the surface of the heat dissipation pipe, maintaining the efficient operation of the heat dissipation system for a long time, and avoiding the decrease in heat dissipation capacity and increase in energy consumption caused by dust accumulation.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0026] like Figures 1-5 As shown, this embodiment proposes an integrated molding die for a plastic packaging container, including a mold frame 1 and a first mold assembly 2 and a second mold assembly 3 installed inside the mold frame 1. The outer walls of both the first mold assembly 2 and the second mold assembly 3 are provided with fins 4 and heat dissipation pipes 5 that cooperate with the fins 4. A protective cover 6 for protecting the fins 4 and heat dissipation pipes 5 is detachably installed on the outer walls of both the first mold assembly 2 and the second mold assembly 3. The protective cover 6 has openings at its top and bottom. Through the setting of the protective cover 6 and the first bolt 10, the fins 4 and heat dissipation pipes 5 can be protected, effectively isolating them from external collisions, thereby significantly reducing the risk of damage to the fins 4 and heat dissipation pipes 5 due to collisions. Simultaneously, the protective cover 6 can also constrain the airflow direction inside the container during use, allowing the airflow to flow along the fins 4, greatly reducing the loss of airflow through lateral diffusion and improving air quality. The contact efficiency and heat transfer intensity between the air and the surfaces of the fins 4 and the heat dissipation pipes 5 are improved, thereby enhancing the overall heat dissipation effect. Multiple evenly distributed first bolts 10 are threaded onto the protective cover 6, facilitating its installation and removal. A dustproof component 7 is detachably installed on the top of the protective cover 6, and a filter component 8 is detachably installed on the bottom. An air inlet pipe 9 with one end inserted into the side wall of the filter component 8 is installed. By setting up the dustproof component 7 and the filter component 8, the dustproof component 7 prevents dust from directly entering the interior of the protective cover 6 during use, and the filter component 8 filters the air supplied by the air inlet pipe 9, reducing the accumulation of dust and other pollutants in the gaps between the fins 4 and on the surface of the heat dissipation pipes 5. This maintains the efficient operation of the heat dissipation system over a long period, preventing a decrease in heat dissipation capacity and an increase in energy consumption due to dust accumulation.
[0027] like Figures 1-3As shown, in a preferred embodiment, based on the above method, the mold frame 1 further includes a base plate 101. A first mounting plate 102 and a second mounting plate 103 are symmetrically mounted on the top of the base plate 101. A through hole 109 is provided between the first mounting plate 102 and the second mounting plate 103 on the base plate 101. A cylinder 106 is fixedly mounted on the side wall of the first mounting plate 102. A first mounting bracket 104 for mounting the first mold assembly 2 is fixedly mounted on the moving end of the cylinder 106. A second mounting bracket 105 for mounting the second mold assembly 3 is connected to the side wall of the second mounting plate 103. Guide rods 107 are fixedly connected to the four corners of the first mounting bracket 104. Wear-resistant sleeves 108 that cooperate with the guide rods 107 are installed through the four corners of the first mounting plate 102. It should be noted that, during use, the first mold assembly 2 and the second mold assembly 3 are respectively mounted on the first mounting bracket 104 and the second mounting bracket 105. When the mold is closed, the cylinder 106 can drive the first mold assembly 2 towards the second mold assembly 3 through the first mounting bracket 104 to close the mold. During the movement of the first mounting bracket 104, the guide rod 107 and the anti-wear sleeve 108 can guide each other, so that the first mold assembly 2 and the second mold assembly 3 can be accurately connected. The through hole 109 can facilitate the discharge of the molded container. The guide rod 107 and the anti-wear sleeve 108 can improve the accuracy and stability of the opening and closing movement of the first mold assembly 2 and the second mold assembly 4, and reduce shaking and wear.
[0028] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the dustproof component 7 further includes a frame 701, a through groove 702 on the frame 701, a dustproof net 703 installed on the inner side of the through groove 702, and a plurality of symmetrically distributed first connecting plates 704 fixedly connected to the side wall of the frame 701, with second bolts 705 installed on the first connecting plates 704. It should be noted that, during use, the first connecting plates 704 and the second bolts 705 facilitate the installation and removal of the frame 701 on the top of the protective cover 6, the through groove 702 facilitates the installation of the dustproof net 703, and the dustproof net 703 effectively blocks dust.
[0029] like Figure 1 , Figure 2 and Figure 5As shown, in a preferred embodiment, based on the above method, the filter assembly 8 further includes a second connecting plate 802, the bottom of which is fixedly connected to a filter box 801. Multiple evenly distributed filter screens 803 are detachably installed inside the filter box 801. It should be noted that during use, external compressed air is delivered to the inside of the filter box 801 through 9, and then filtered through the multiple filter screens 803 inside the filter box 801. After filtration, the air is then sent into the interior of the anti-collision cover 6 to cool the fins 4 and the heat dissipation pipe 5.
[0030] Specifically, the working principle of this one-piece mold for plastic packaging containers is as follows: During production, the preform can be blow-molded in the mold cavity between the mold frame 1 and the first mold component 2. After molding, compressed air from the outside will be transported to the interior of the filter component 8 through the air inlet pipe 9. The filter component 8 will filter the incoming air to prevent dust and other pollutants in the air from directly entering the interior of the protective cover 6. The air entering the protective cover 6 will flow upward along the fins 4 to dissipate heat from the fins 4 and the heat dissipation pipe 5, and at the same time dissipate heat from the plastic bottle in the mold cavity. The air entering the protective cover 6 will finally be discharged through the opening at the top of the protective cover 6. When the air is discharged, it will blow away the dust accumulated on the top of the dustproof component 7, preventing dust accumulation from causing blockage of the dustproof component 7.
[0031] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
