Description

Technical Field

[0001] This utility model relates to the field of cooling technology for automatic hot-fill blow molding dies, and more specifically, to a self-cooling bottle clamp structure for an automatic hot-fill blow molding die. Background Technology

[0002] In the field of hot-fill automatic blow molding, the bottle neck area easily accumulates heat due to the high-temperature liquid being filled. Traditional mold cooling systems mostly use fixed pipelines or external indirect cooling methods, resulting in low cooling efficiency and uneven temperature distribution at the bottle neck. Prolonged high-temperature operation can easily lead to bottle neck deformation, requiring frequent shutdowns for cooling, which seriously affects production efficiency. In addition, traditional pipeline structures are not detachable, resulting in high maintenance and replacement costs, making it difficult to meet the demands of high-intensity continuous production. Utility Model Content

[0003] The present invention provides a self-cooling bottle clamping structure for an automatic hot-fill blow molding die, which integrates a bottle clamping structure with high-efficiency cooling and easy maintenance, thereby overcoming the shortcomings of the prior art.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A self-cooling bottle clamping structure for an automatic hot-fill blow molding die includes:

[0006] The semi-circular arc-shaped clamp structure has a bottle clamp formed on its inner arc side and a cooling circuit inside.

[0007] Both the inlet and outlet pipes are composed of multiple detachable unit pipes connected in series;

[0008] The outlet of the water inlet pipe is detachably connected to the inlet of the cooling circuit, and the inlet of the water outlet pipe is detachably connected to the outlet of the cooling circuit.

[0009] The cooling circuit is connected to an external cooling water source through the inlet and outlet pipes to achieve rapid circulation of cooling water.

[0010] Preferably, the outer arc side of the clamping structure is provided with a plane, and the inlet and outlet of the cooling circuit are both located on this plane.

[0011] Preferably, both the inlet pipe and the outlet pipe are composed of multiple unit pipes with progressively increasing diameters connected in series by threaded connections.

[0012] Preferably, both the inlet pipe and the outlet pipe are detachably connected to the cooling circuit via threaded connections.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a cooling circuit inside the clamp structure to rapidly circulate with an external water source, directly removing heat from the bottle mouth and significantly reducing the temperature. This makes it easier to maintain long-term bottle blowing, ensuring the bottle mouth does not deform and improving production efficiency. The inlet and outlet pipes adopt a multi-section detachable unit pipe series design, so when there is partial damage, only the faulty unit needs to be replaced, without the need for complete disassembly, which greatly reduces maintenance costs and time.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, embodiments of this utility model are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0016] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] Please refer to Figure 1 This embodiment provides a self-cooling bottle clamp 12 structure for an automatic hot-fill blow molding die, including a clamp structure 1, a water inlet pipe 2, and a water outlet pipe 3.

[0021] Among them, the clamping structure 1 is a semi-circular arc structure, with the inner arc side forming the bottle clamping opening 12, and a cooling circuit 11 is provided inside.

[0022] Furthermore, the inlet pipe 2 and outlet pipe 3 are unit pipes with progressively increasing diameters, connected in series by threads. The pipe diameter gradient design can adjust the water flow speed and pressure, avoiding water flow turbulence or pressure loss caused by sudden changes in pipe diameter. The threaded connection method ensures sealing, while simplifying the assembly and disassembly process and enhancing system flexibility.

[0023] Furthermore, the outlet of the water inlet pipe 2 is detachably connected to the inlet of the cooling circuit 11 by means of a threaded connection, and the inlet of the water outlet pipe 3 is detachably connected to the outlet of the cooling circuit 11 by means of a threaded connection. Here, the connection between the water inlet pipe 2 and the water outlet pipe 3 and the cooling circuit 11 adopts a threaded interface, which provides reliable mechanical fixing and sealing performance to prevent cooling water leakage. In addition, the quick disassembly and assembly design facilitates the replacement of faulty parts or the cleaning and maintenance of the entire system, further improving practicality.

[0024] Furthermore, the cooling circuit 11 is connected to an external cooling water source through the inlet pipe 2 and the outlet pipe 3 to achieve rapid circulation of cooling water.

[0025] In this embodiment, the cooling circuit 11 embedded in the semi-circular clamp structure 1 is connected to an external water source, and a closed-loop circulation system is formed by the detachable water inlet pipe 2 and water outlet pipe 3, so that the cooling water flows rapidly in the circuit.

[0026] In this embodiment, the outer arc side of the clamp structure 1 is designed as a plane, integrating the inlet and outlet of the cooling circuit 11 onto the plane. The planar structure facilitates precise docking with external water pipes or fixing devices, improving installation stability.
