However, in the prior art, the cooling water channel of the mould cavity is generally formed by spirally winding one cooling water groove along the outer side wall of the mould cavity, and the mould cavity with the structure has the following disadvantages:

[0003] The flow process of the cooling medium along the cooling water channel is relatively long, and as the cooling medium flows in the cooling water channel, the temperature of the cooling medium gradually rises, so that when the cooling medium flows through the rear section of the cooling water channel, the cooling effect of the bottle blank in the mould cavity corresponding to the rear section of the cooling water channel is significantly reduced due to the high temperature of the cooling medium itself, the overall cooling effect of the mould cavity is affected, and sufficient cooling cannot be achieved.

[0004] The cooling water channel only has a single water inlet, the water source is single, the water source flow cannot be fully utilized, and the cooling efficiency is relatively low.

[0050] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0051] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model. Example 1:

[0052] like Figure 1 As shown, this embodiment discloses a mold cavity with multiple cooling layers distributed circumferentially, including a mold body. A preform forming cavity is provided axially within the mold body. Circumferential reinforcing ribs 1 are provided at both ends of the outer wall of the mold body, circumferentially surrounding the mold body and connected end to end. Multiple layered straight reinforcing ribs 2 are sequentially provided circumferentially between two circumferential reinforcing ribs 1. The layered straight reinforcing ribs 2 extend parallel to the axial direction of the mold body and are connected at both ends to the circumferential reinforcing ribs 1 at both ends of the mold body. A mold cavity cooling layer 13 is formed between two adjacent layered straight reinforcing ribs 2. The multiple layered straight reinforcing ribs 2 form at least two circumferentially distributed mold cavity cooling layers 13 on the outer wall of the mold body, with each mold cavity cooling layer 13 being separated and independent from each other. The mold cavity cooling layer 13 has a layered reinforcing rib group, which forms a cooling water channel for the flow of cooling medium within the mold cavity cooling layer 13.

[0053] The layered reinforcing rib group includes a straight layered reinforcing rib 11 extending parallel to the axial direction of the mold body; one end of the straight layered reinforcing rib 11 is connected to the circumferential reinforcing rib 1 at one end of the mold body, and the other end has an axial distance J between it and the circumferential reinforcing rib 1 at the other end of the mold body, thereby forming a sprue 12.

[0054] Two circumferential reinforcing ribs 1, one of which is a layered straight reinforcing rib 2, forms an inlet C and an inlet channel D between the two circumferential reinforcing ribs 1 and the other layered straight reinforcing rib 2, which forms an outlet channel F and an outlet G between the two circumferential reinforcing ribs 1 and the other layered straight reinforcing rib 2, which forms an outlet channel F; the inlet channel D and the outlet channel F are connected via a water outlet 12.

[0055] In actual use, the inlet C and outlet G can be interchanged according to the usage requirements. After the interchange, the order in which the cooling medium flows through the mold cavity cooling layer 13 is reversed, and the two can achieve the same cooling effect.

[0056] In a preferred embodiment, the layered straight section reinforcing rib 11 is positioned at the midpoint between two adjacent layered straight section reinforcing ribs 2, thereby making the spacing between the layered straight section reinforcing rib 11 and the two adjacent layered straight section reinforcing ribs 2 equal, that is, the flow cross-sectional size of the water inlet tank D and the water outlet tank F are equal.

[0057] In a preferred embodiment, the projected length of the axial spacing J on the longitudinal section is equal to the spacing between the layered straight section reinforcing rib 11 and the layered straight section reinforcing rib 2. That is, the flow cross-sections of the water outlet 12, the inlet channel D, and the outlet channel F are equal.

[0058] In this embodiment, the straight section reinforcing ribs 11 in each mold cavity cooling layer 13 are connected to the same circumferential reinforcing rib 1. The axial spacing J in each mold cavity cooling layer 13 is distributed along the same circumferential direction of the mold body. Example 2:

[0059] like Figure 2 As shown, the specific implementation content of this embodiment is largely the same as that of Embodiment 1, except that the straight section reinforcing ribs 11 in the adjacent mold cavity cooling layers 13 are connected to different circumferential reinforcing ribs 1. The axial spacing J in the adjacent mold cavity cooling layers 13 is staggered vertically along the circumference of the mold body. Example 3:

[0060] like Figure 3 As shown, the specific implementation content of this embodiment is roughly the same as that of Embodiment 1, except that: the layer reinforcing rib group includes multiple straight layer reinforcing ribs 3 extending parallel to the axial direction of the mold body; the multiple straight layer reinforcing ribs 3 are distributed sequentially along the circumferential direction of the outer wall of the mold body, and the connecting ends are alternately connected to two circumferential reinforcing ribs 1, and the other end of the connecting end has an alternate axial spacing A and an axial spacing B with the two circumferential reinforcing ribs 1.

[0061] One end of one of the straight reinforcing ribs 3 is connected to the circumferential reinforcing rib 1 at one end of the mold body, and the other end is axially spaced A from the circumferential reinforcing rib 1 at the other end of the mold body, thus forming the first gate 5; one end of the other straight reinforcing rib 3 is axially spaced B from the circumferential reinforcing rib 1 at one end of the mold body, thus forming the second gate 6, and the other end is connected to the circumferential reinforcing rib 1 at the other end of the mold body.

[0062] Two circumferential reinforcing ribs 1, one of the layered straight reinforcing ribs 2 and one of the layered straight reinforcing ribs 3 form an inlet C and an inlet channel D; two circumferential reinforcing ribs 1 and two adjacent layered straight reinforcing ribs 3 form a direct current channel E; two circumferential reinforcing ribs 1, another layered straight reinforcing rib 2 and another layered straight reinforcing rib 3 form an outlet channel F and an outlet G; the inlet channel D and the direct current channel E are connected via the first outlet 5, and the direct current channel E and the outlet channel F are connected via the second outlet 6.

[0063] In actual use, the inlet C and outlet G can be interchanged according to the usage requirements. After the interchange, the order in which the cooling medium flows through the mold cavity cooling layer 13 is reversed, and the two can achieve the same cooling effect.

[0064] In a preferred embodiment, multiple layered straight reinforcing ribs 3 are evenly distributed between two adjacent layered straight reinforcing ribs 2, so that the spacing between the layered straight reinforcing ribs 3 and the adjacent layered straight reinforcing ribs 2 is equal to the spacing between adjacent layered straight reinforcing ribs 3, that is, the flow cross-sections of the inlet tank D, the outlet tank F, and the direct flow tank E are equal.

[0065] In a preferred embodiment, the projected length of the axial spacing A on the longitudinal section is equal to the spacing between the layered straight reinforcing rib 3 and the adjacent layered straight reinforcing rib 2, which is equal to the spacing between adjacent layered straight reinforcing ribs 3. Example 4:

[0066] like Figure 4 As shown, the specific implementation content of this embodiment is roughly the same as that of Embodiment 1. The difference is that: the layer reinforcing rib group includes a layer ring segment reinforcing rib 4 extending circumferentially along the outer side wall of the mold body; one end of the layer ring segment reinforcing rib 4 is connected to one of the two adjacent layered straight segment reinforcing ribs 2, and the other end has a circumferential spacing K between it and the other of the two adjacent layered straight segment reinforcing ribs 2, thereby forming a water outlet 12.

[0067] One of the circumferential reinforcing ribs 1, one of the layered straight reinforcing ribs 2, and one of the layered ring reinforcing ribs 4 form an inlet C and an inlet channel D; another circumferential reinforcing rib 1, one of the layered straight reinforcing ribs 2, and one of the layered ring reinforcing ribs 4 form an outlet channel F and an outlet G; the inlet channel D and the outlet channel F are connected via the outlet 12.

[0068] In actual use, the inlet C and outlet G can be interchanged according to the usage requirements. After the interchange, the order in which the cooling medium flows through the cooling water circuit is reversed, and both can achieve the same cooling effect.

[0069] In a preferred embodiment, the layer ring segment reinforcing rib 4 is positioned in the middle between the two circumferential reinforcing ribs 1, so that the spacing between the layer ring segment reinforcing rib 4 and the two circumferential reinforcing ribs 1 is equal, that is, the flow cross-sectional size of the water inlet channel D and the water outlet channel F is equal.

[0070] In a preferred embodiment, the projected length of the circumferential spacing K on the longitudinal section is equal to the spacing between the layer ring reinforcing rib 4 and the circumferential reinforcing rib 1. Example 5:

[0071] like Figure 5 As shown, the specific implementation content of this embodiment is roughly the same as that of Embodiment 1, except that: the layer reinforcing rib group includes multiple layer ring segment reinforcing ribs 4 extending circumferentially along the outer side wall of the mold body; the multiple layer ring segment reinforcing ribs 4 are distributed sequentially along the axial direction parallel to the mold body, and the connecting ends are alternately connected to two adjacent layer straight segment reinforcing ribs 2, respectively. The other end of the connecting end has an alternate circumferential spacing L and a circumferential spacing M with the two adjacent layer straight segment reinforcing ribs 2, thereby forming the first water outlet 5 and the second water outlet 6.

[0072] One of the circumferential reinforcing ribs 1, two adjacent layered straight reinforcing ribs 2, and layered ring reinforcing ribs 4 form an inlet C and an inlet channel D; two adjacent layered straight reinforcing ribs 2 and two adjacent layered ring reinforcing ribs 4 form an annular channel H; another circumferential reinforcing rib 1, two adjacent layered straight reinforcing ribs 2, and layered ring reinforcing ribs 4 form an outlet channel F and an outlet G; the inlet channel D and the outlet channel F are connected via the first outlet 5, the annular channel H, and the second outlet 6.

[0073] In a preferred embodiment, multiple layered ring-shaped reinforcing ribs 4 are evenly distributed between two circumferential reinforcing ribs 1, such that the distance between a circumferential reinforcing rib 1 and its adjacent layered ring-shaped reinforcing rib 4 is equal to the distance between adjacent layered ring-shaped reinforcing ribs 4, i.e., the flow cross-sectional sizes of the inlet channel D, outlet channel F, and circulation channel H are equal. The projected lengths of the circumferential spacing L and circumferential spacing M on the longitudinal section are equal to the distance between a circumferential reinforcing rib 1 and its adjacent layered ring-shaped reinforcing rib 4, which is also equal to the distance between adjacent layered ring-shaped reinforcing ribs 4. Example 6:

[0074] like Figure 6As shown, the specific implementation of the embodiment is substantially the same as that of Embodiment One, with the difference being that the layer reinforcement rib group comprises layer straight section reinforcement ribs 11 extending along the axial direction of the mold body and layer ring section reinforcement ribs 14 extending along the circumferential direction of the outer side wall of the mold body; the two ends of the layer straight section reinforcement rib 11 are respectively provided with an axial spacing A and an axial spacing B with the circumferential reinforcement rib 1 at the two ends of the mold body, thereby forming a first water outlet 5 and a second water outlet 6; one end of the layer ring section reinforcement rib 14 is connected with one of the layer straight section reinforcement ribs 2, and the other end is connected with one end of the layer straight section reinforcement rib 11.

[0075] The water inlet C is formed between the layer ring section reinforcement rib 14, one of the circumferential reinforcement ribs 1, and one of the layer straight section reinforcement ribs 2; the water inlet channel D is formed between the two circumferential reinforcement ribs 1, the layer straight section reinforcement rib 11, and the other layer straight section reinforcement rib 2; and the water outlet channel F and the water outlet G are formed between the layer straight section reinforcement rib 11, the layer ring section reinforcement rib 14, one of the layer straight section reinforcement ribs 2, and the other circumferential reinforcement rib 1. The water inlet C and the water inlet channel D are connected through the first water outlet 5, and the water inlet channel D and the water outlet channel F are connected through the second water outlet 6.

[0076] In actual use, the water inlet C and the water outlet G can be interchanged according to the use requirements, and after interchanging, the order of the cooling medium flowing in the mold cavity cooling layer 13 is reversed, and both can achieve the same cooling effect.

[0077] As a preferred implementation, the layer straight section reinforcement rib 11 is arranged at the middle position between the two adjacent layer straight section reinforcement ribs 2, so that the spacing between the layer straight section reinforcement rib 11 and the two adjacent layer straight section reinforcement ribs 2 is equal, that is, the flow cross-sectional size of the water inlet channel D and the water outlet channel F is equal.

[0078] As a preferred implementation, the projection length of the axial spacing A on the longitudinal section is equal to the spacing between the layer straight section reinforcement rib 11 and the layer straight section reinforcement rib 2. The projection length of the axial spacing B on the longitudinal section is equal to the spacing between the layer straight section reinforcement rib 11 and the layer straight section reinforcement rib 2. That is, the flow cross-sectional size of the first water outlet 5, the second water outlet 6, the water inlet channel D, and the water outlet channel F is equal.

[0079] In the embodiment, the layer ring section reinforcement ribs 14 in each layer mold cavity cooling layer 13 are distributed along the same circumferential direction of the mold body. The water inlets C and the water outlets G in each layer mold cavity cooling layer 13 are respectively distributed along the same circumferential direction of the mold body. Embodiment Seven:

[0080] As shown in the drawings, Figure 7As shown, the specific implementation content of this embodiment is largely the same as that of Embodiment 5, except that the reinforcing ribs 14 of the interlayer rings in the adjacent mold cavity cooling layers 13 are staggered vertically along the circumference of the mold body. The water inlets C and water outlets G in the adjacent mold cavity cooling layers 13 are staggered vertically along the circumference of the mold body, respectively. Example 8:

[0081] like Figure 8 As shown, the specific implementation content of this embodiment is largely the same as that of Embodiment 1, except that one end of the layer ring segment reinforcing rib 14 is connected to one of the layered straight segment reinforcing ribs 2, and the other end is connected between the two ends of the layered straight segment reinforcing rib 11. Preferably, the layer ring segment reinforcing rib 14 is connected to the middle of the layered straight segment reinforcing rib 11.

[0082] One layer of straight reinforcing rib 2, one layer of circumferential reinforcing rib 1, one layer of straight reinforcing rib 11, and one layer of annular reinforcing rib 14 form an inlet C and an inlet channel D; another layer of straight reinforcing rib 2, one layer of straight reinforcing rib 11, and two circumferential reinforcing ribs 1 form a direct current channel E; one layer of straight reinforcing rib 2, one layer of circumferential reinforcing rib 1, one layer of straight reinforcing rib 11, and one layer of annular reinforcing rib 14 form an outlet channel F and an outlet G; the inlet channel D and the direct current channel E are connected via the first outlet 5, and the direct current channel E and the outlet channel F are connected via the second outlet 6.

[0083] In actual use, the inlet C and outlet G can be interchanged according to the usage requirements. After the interchange, the order in which the cooling medium flows through the mold cavity cooling layer 13 is reversed, and the two can achieve the same cooling effect.

[0084] In a preferred embodiment, the layered straight section reinforcing rib 11 is positioned at the midpoint between two adjacent layered straight section reinforcing ribs 2, thereby making the spacing between the layered straight section reinforcing rib 11 and the two adjacent layered straight section reinforcing ribs 2 equal, that is, the flow cross-sectional size of the water inlet tank D, the direct flow tank E and the water outlet tank F are equal.

[0085] In a preferred embodiment, the projected length of the axial spacing A on the longitudinal section is equal to the spacing between the layered straight section reinforcing rib 11 and the layered straight section reinforcing rib 2. The projected length of the axial spacing B on the longitudinal section is equal to the spacing between the layered straight section reinforcing rib 11 and the layered straight section reinforcing rib 2. That is, the flow cross-sectional sizes of the first water outlet 5, the second water outlet 6, the inlet channel D, the direct current channel E, and the outlet channel F are equal. Example 9:

A plurality of layered straight section reinforcing ribs 2 are arranged circumferentially between the two circumferential reinforcing ribs 1. The layered straight section reinforcing ribs 2 extend parallel to the axial direction of the mold body and are connected to the circumferential reinforcing ribs 1 at both ends of the mold body. A layer of mold cavity cooling layer 13 is formed between two adjacent layered straight section reinforcing ribs 2. The plurality of layered straight section reinforcing ribs 2 form at least two layers of mold cavity cooling layers 13 distributed circumferentially on the outer side wall of the mold body, and each layer of mold cavity cooling layer 13 is separated and independent. A plurality of partition reinforcing rib groups are arranged axially in the mold cavity cooling layer 13. The partition reinforcing rib groups separate the mold cavity cooling layer 13 into a plurality of mold cavity cooling zones distributed axially, and each mold cavity cooling zone forms a cooling water channel for the flow of cooling medium.

[0087] As a preferred embodiment, the partition reinforcing rib group comprises a first partition ring section reinforcing rib 7 and a second partition ring section reinforcing rib 8 extending circumferentially along the outer side wall of the mold body, and a partition straight section reinforcing rib 9 extending parallel to the axial direction of the mold body. The first partition ring section reinforcing rib 7 has an axial spacing A between one of the two circumferential reinforcing ribs 1 or the second partition ring section reinforcing rib 8 of the previous partition reinforcing rib group, thereby forming a first water outlet 5. One end of the first partition ring section reinforcing rib 7 is connected to one of the two adjacent layered straight section reinforcing ribs 2, and the other end is connected to one end of the partition straight section reinforcing rib 9. The partition straight section reinforcing rib 9 extends towards the next partition reinforcing rib group. The second partition ring section reinforcing rib 8 has an axial spacing B between the other of the two circumferential reinforcing ribs 1 or the first partition ring section reinforcing rib 7 of the next partition reinforcing rib group, thereby forming a second water outlet 6.
