Description

Technical Field

[0001] This utility model belongs to the field of bottle preform mold technology, and relates to a double spiral cooling water tank structure for multi-cavity bottle preform molds. Background Technology

[0002] Preform molds are special mold parts used to produce plastic bottles. During the processing, a special cooling structure is required to cool the preform mold. However, traditional cooling structures are designed with a single cooling water channel. The water flows through the mold part all the way to the bottom of the mold to achieve cooling. This structure has two drawbacks: first, the cooling water channel has a long stroke, resulting in poor cooling efficiency; second, the cross-sectional area of ​​the cavity between the bottom of the mold cavity and the main body of the mold cavity is too large, resulting in a slow water flow rate at the bottom of the mold cavity, which in turn affects the cooling effect at the bottom of the mold cavity. Summary of the Invention

[0003] The purpose of this invention is to provide a double-helix cooling water tank structure for multi-cavity preform molds to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] The multi-cavity preform mold with a double-helix cooling water tank structure includes a main support plate, a double-helix water channel, and an independent cooling water channel. The main support plate has four sets of mold cavities arranged side by side from top to bottom inside. The mold cavity body has a mold cavity bottom at its tail end, and a flow-limiting ring is provided between the mold cavity bottom and the mold cavity body. The double-helix water channel and the independent cooling water channel are arranged on one side of the main support plate. The double-helix water channel is connected to the inside of the mold cavity body, and the independent cooling water channel is connected to the inside of the mold cavity bottom. The double-helix water channel has a spiral groove inside.

[0006] In the above-mentioned double-spiral cooling water tank structure of the multi-cavity preform mold, the main support plate has multiple mounting slots inside, and the main body of the mold cavity is set inside the mounting slots.

[0007] In the above-mentioned double-spiral cooling water tank structure of the multi-cavity bottle preform mold, the double-spiral water route consists of a water channel vertical pipe, two water channel horizontal pipes, multiple water channel upper insertion pipes, and multiple water channel lower insertion pipes. The two water channel horizontal pipes are respectively connected to the top and bottom of the water channel vertical pipe. The multiple water channel upper insertion pipes are connected to one of the water channel horizontal pipes, and the multiple water channel lower insertion pipes are connected to the other water channel horizontal pipe.

[0008] In the above-mentioned double-spiral cooling water tank structure of the multi-cavity preform mold, multiple water inlet pipes and water outlet pipes are arranged side by side and evenly, and the multiple water inlet pipes and water outlet pipes are connected to the main body of the mold cavity.

[0009] In the above-mentioned double-spiral cooling water tank structure of the multi-cavity bottle preform mold, the independent cooling water route consists of a water channel vertical pipe II, two water channel horizontal pipe II, multiple water channel upper insertion pipe II, and multiple water channel lower insertion pipe II. The two water channel horizontal pipe II are respectively connected to the top and bottom of the water channel vertical pipe II. The multiple water channel upper insertion pipe II are connected to one of the water channel horizontal pipe II, and the multiple water channel lower insertion pipe II are connected to another water channel horizontal pipe II.

[0010] In the above-mentioned double-spiral cooling water tank structure of the multi-cavity preform mold, the multiple upper water inlet pipes and lower water inlet pipes are arranged side by side and evenly, and the multiple upper water inlet pipes and lower water inlet pipes are connected to the bottom of the mold cavity.

[0011] Compared with the prior art, the advantages of the double-helix cooling water tank structure of the multi-cavity bottle preform mold of this utility model are:

[0012] 1. This application adopts a double-helix water channel structure, which changes the original one set of cooling water channels into two sets of cooling water channels, namely the double-helix water channel of the main body of the mold cavity and the independent cooling water channel of the bottom of the mold cavity. This shortens the stroke of the cooling water channel, and the spiral groove has less resistance to water. Under the same water pressure and time, the water flow rate is faster and can carry away more heat.

[0013] 2. The mold cavity bottom of this application adopts an independent cooling water channel. To address the problem of excessive cross-sectional area of ​​the cavity between the mold cavity bottom and the mold cavity body and poor cooling effect of the mold cavity bottom, a flow-limiting ring structure is adopted. The flow-limiting ring is installed between the mold cavity bottom and the mold cavity body, which reduces the cross-sectional area of ​​the cavity between the mold cavity bottom and the mold cavity body. Under the same water pressure, compared with the original cooling water channel structure, the water flow rate at the bottom of the mold cavity is faster, thereby achieving the ideal cooling effect.

The tail end of the mold cavity body 4 is provided with a mold cavity bottom 13, and a flow-limiting ring 14 is provided between the mold cavity bottom 13 and the mold cavity body 4. The double-helix water channel 2 and the independent cooling water channel 3 are provided on one side of the main support plate 1. The double-helix water channel 2 is connected to the inside of the mold cavity body 4, and the independent cooling water channel 3 is connected to the inside of the mold cavity bottom 13. The double-helix water channel 2 is provided with a spiral groove 15.

Specifically, the main support plate 1 has multiple mounting slots inside, and the mold cavity body 4 is set inside the mounting slots.

The two horizontal water pipes 6 are respectively connected to the top and bottom of the vertical water pipe 5. The multiple upper water pipes 7 are connected to one of the horizontal water pipes 6, and the multiple lower water pipes 8 are connected to the other horizontal water pipe 6.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the double spiral cooling water tank structure of the multi-cavity preform mold of this utility model has multiple water inlet pipes 7 and water outlet pipes 8 arranged side by side and evenly, and the multiple water inlet pipes 7 and water outlet pipes 8 are connected to the mold cavity body 4. The water inlet pipes 7 are connected to the first and second group of mold cavity bodies 4, while the water outlet pipes 8 are connected to the third and fourth group of mold cavity bodies 4.

[0023] like Figure 1 , Figure 2 , Figure 3As shown, the double spiral cooling water tank structure of the multi-cavity bottle preform mold of this utility model is specifically composed of an independent cooling water channel 3 consisting of a vertical water channel pipe 9, two horizontal water channel pipes 10, multiple upper water channel pipes 11, and multiple lower water channel pipes 12.

[0025] This utility model relates to a double-helix cooling water channel structure for a multi-cavity preform mold. It utilizes a double-helix water channel structure, replacing the original single cooling water channel with two separate cooling water channels: a double-helix water channel 2 for the main body 4 and an independent cooling water channel 3 for the bottom 13 of the cavity. The double-helix water channel 2 is connected to the main body 4, primarily cooling the main body 4, while the independent cooling water channel 3 is connected to the bottom 13 of the cavity, thus cooling the bottom 13. This structural design significantly shortens the entire cooling water channel's travel distance, particularly improving the cooling of the bottom 13 of the cavity. Furthermore, the spiral groove 15 provides less resistance to water flow, resulting in a faster water flow rate under the same water pressure and time, thus removing more heat and improving the cooling effect on the bottom 13 of the cavity.
