Description

Technical Field

[0001] The utility model relates to the technical field of cooling systems in molds, in particular to a cooling system for a mold and a mold. Background Art

[0002] During the high-speed, high-pressure injection phase of the injection molding process, the plastic melt quickly and fully fills the front half of the cavity of a product with a deep cavity and thin walls. However, as the injection process reaches the end of the deep cavity, the thin walls of the deep cavity and the influence of the cooling water can cause the intermediate flow layer of the plastic melt to thin or solidify prematurely. This can easily lead to a series of adverse consequences, such as abnormally high injection pressure, localized glue shortages in the product, and substandard pressure retention.

[0003] The current layout design usually adopts a straight-through series cooling water channel. However, when the product wall thickness is unevenly distributed, the above design cannot ensure that the plastic melt fully penetrates and fills the thin-walled area, thereby increasing the instability of the product production process and increasing the product scrap rate.

[0033] During the high-speed, high-pressure injection phase of the injection molding process, the plastic melt can quickly and fully fill the front half of the cavity 11 of a product with a deep cavity and thin walls. However, as the injection process reaches the end of the deep cavity, the thin walls of the deep cavity and the cooling water can cause the middle flow layer of the plastic melt to become thinner or solidify prematurely, which can easily lead to a series of adverse consequences, such as abnormally high injection pressure, localized glue shortages in the product, and substandard pressure retention.

[0034] The current layout design usually adopts a straight-through series cooling water channel. However, when the product wall thickness is unevenly distributed, the above design cannot ensure that the plastic melt fully penetrates and fills the thin-walled area, thereby increasing the instability of the product production process and increasing the product scrap rate.

[0035] The utility model provides a cooling system for a mold.

[0036] See also Figure 1 、 Figures 3 to 7, in one embodiment of the present utility model, the cooling system of the mold includes a template 1, and the template 1 has a cavity 11;

[0037] a cooling system 2, the cooling system 2 being disposed within the template 1 and surrounding the periphery of the cavity 11, the cooling system 2 comprising a first cooling water channel and a second cooling water channel spaced apart along the axial direction of the cavity 11; and

[0038] A circulating water channel 3 is provided in the template 1 and includes a first circulating water channel 31 and a second circulating water channel 32. The first circulating water channel 31 is connected to the first cooling water channel, and the second circulating water channel 32 is connected to the second cooling water channel. The circulating water channel 3 is used to transport cooling water to the cooling system 2 and discharge the cooling water in the cooling system 2.

[0039] In this embodiment, the template 1 has a plurality of spaced cavities 11, and the cavities 11 can be extended along the width direction of the mold. A cooling system 2 is provided around the outer periphery of each cavity 11, thereby increasing the cooling water interaction area between the cooling system 2 and the cavity 11, thereby improving the cooling efficiency of the cooling water in the cooling system 2 on the product. In order to further improve the controllability of the cooling system 2 in regulating the temperature of the product at different wall thickness positions, the cooling system 2 includes a first cooling water channel and a second cooling water channel spaced along the axial direction of the cavity 11. The cooling system 2 can be provided with multiple sections of the first cooling water channel and multiple sections of the second cooling water channel at intervals along the circumferential direction of the cavity 11 according to the size of the cavity 11, so as to better cool the product on the cavity 11. In the axial direction of the cavity 11, according to the thickness of the product wall, the front half of the cavity 11 can transport cooling water through the first cooling water channel, and the back half of the cavity 11 can be provided with cooling water transported through the second cooling water channel. The first cooling water channel and the second cooling water channel can be connected to different circulating water channels 3 separately, so that multiple sections of the first cooling water channel and multiple sections of the second cooling water channel cooperate with the corresponding circulating water channels 3 to form a multi-section cooling water channel. In order to better adjust the content of cooling water in the first cooling water channel and the second cooling water channel, the circulating water channel includes a first circulating water channel 31 and a second circulating water channel 32, the first circulating water channel 31 is connected to the first cooling water channel, and the second circulating water channel 32 is connected to the second cooling water channel. By controlling the opening or closing of the water inlet and outlet of the first circulating water channel 31 or the second circulating water channel 32, it is convenient for the operator to adjust the temperature of different parts of the product, thereby better controlling the flow state of the plastic melt, which is more conducive to ensuring the quality of product molding and the stability of the process.

[0040] The technical solution of the present invention is to adopt a first cooling water channel and a second cooling water channel to be arranged around the outer periphery of the mold cavity 11. The first cooling water channel and the second cooling water channel are respectively equipped with a circulating water channel 3 to form a multi-stage cooling water channel. In the case of uneven wall thickness of the product, compared with the cooling water channel method of adopting a straight-through series water transportation method, the present application adopts a segmented control cooling water transportation method to adjust the balance of the product during injection molding, thereby reducing the occurrence of undesirable phenomena such as excessive injection pressure, product glue deficiency and poor pressure holding.

[0041] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, in this embodiment, the cooling system of the mold further includes a water barrier 4 , and the first cooling water channel and the second cooling water channel are separated by the water barrier 4 .

[0042] In this embodiment, the first cooling water channel can be set as an annular cavity and connected to the circulating water channel 3, so that the first cooling water channel can reduce the resistance of the cooling water flow, so that the cooling water can flow more smoothly in the first cooling water channel. The first cooling water channel and the second cooling water channel are separated by a water barrier 4, and the first cooling water channel and the second cooling water channel are each connected to the circulating water channel 3, so that the cooling system 2 is divided into two sections of a first cooling water channel and a second cooling water channel that can be controlled separately, so that the operator can control the opening or closing of the first cooling water channel or the second cooling water channel by controlling the opening or closing of the water inlet and outlet of the circulating water channel 3, thereby further facilitating the operator to regulate the temperature of different positions of the product. The water barrier 4 is also used to improve the sealing between the first cooling water channel and the second cooling water channel to prevent the cooling water between the first cooling water channel and the second cooling water channel from circulating with each other and affecting the control of the operator.

[0043] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, in this embodiment, the first cooling water path has a plurality of water flow cavities 21 arranged at intervals along the circumference of the mold cavity 11, and the plurality of water flow cavities 21 are interconnected. A plurality of water isolation blocks 4 are provided, and the water isolation blocks 4 are inserted one-to-one into the plurality of water flow cavities 21. A water flow channel 43 is formed between the side wall of the water isolation block 4 and the inner wall of the water flow cavity 21.

[0044] In this embodiment, the water passage cavity 21 can be arranged in an arc shape along the cross-section of the axial direction of the mold cavity 11, thereby better surrounding the outer periphery of the mold cavity 11. The water passage cavity 21 has water passage channels 43 at both ends of the arc. The water passage channels 43 can be arranged in an arc shape along the cross-section of the axial direction of the mold cavity 11, so that the water passage cavity 21 can reduce the resistance to the flow of cooling water, allowing the cooling water to flow more smoothly within each water passage cavity 21. One end of the water passage cavity 21 is open, and multiple water passage cavities 21 are arranged along the axial direction of the mold cavity 11 toward the open end, so that the multiple water passage cavities 21 are wrapped around the outer periphery of the mold cavity 11, thereby improving the cooling efficiency of the cooling water on the product. By providing multiple water passage cavities 21 that are interconnected, it is convenient for cooling water to be transported to each water passage cavity 21 through the circulating water path 3, and it is convenient for cooling water to be discharged from the water passage cavities 21 through the circulating water path 3.

[0045] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, in this embodiment, the water barrier 4 includes a main body 41, and sealing protrusions 42 are protruded on both sides of the main body 41. The sealing protrusions 42 are arranged on the side of the main body 41 away from the opening end of the water flow chamber 21. A water flow channel 43 is formed between the outer wall of the main body 41, the outer wall of the sealing protrusion 42 and the inner wall of the water flow chamber 21.

[0046] In this embodiment, the shape of the body 41 can match the shape of the water passage cavity 21, so that the body 41 can better fill the water passage cavity 21. Sealing protrusions 42 are provided on both sides of the body 41. A water passage 43 is formed between the outer wall of the body 41, the outer wall of the sealing protrusions 42, and the inner wall of the water passage cavity 21. The sealing protrusions 42 are used to separate the first cooling water channel and the second cooling water channel, preventing mutual flow between the first cooling water channel and the second cooling water channel, thereby further improving the sealing of the first cooling water channel and the second cooling water channel, and making it easier for the operator to control the first cooling water channel and the second cooling water channel to adjust the mold temperature.

[0047] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, in this embodiment, the second cooling water circuit includes a plurality of cooling pipes 22 arranged at intervals along the circumference of the cavity 11, and the plurality of cooling pipes 22 are all connected to the second circulating water circuit 32. The cooling pipes 22 are arranged on the side of the water transfer cavity 21 away from the open end of the water transfer cavity 21.

[0048] In this embodiment, by configuring the second cooling water circuit as a cooling pipe 22 distinct from the first cooling water circuit, at least two different types of multi-stage cooling water circuits are formed within the mold. The use of cooling pipes 22 also reduces mold manufacturing costs. By arranging multiple cooling pipes 22 at intervals along the circumference of the mold cavity 11, the cooling efficiency of the cooling water within the multiple cooling pipes 22 on the product is improved. The circulating water circuit 3 connects to each of the multiple cooling pipes 22, facilitating the delivery of cooling water to and discharge from the cooling pipes 22.

[0049] like Figures 3 to 5 As shown, in this embodiment, the cooling system of the mold also includes a first insert 5, which is connected to one end of the cavity 11. The first insert 5 has a plurality of first water grooves 51 on an end face close to the cavity 11, and the plurality of first water grooves 51 are connected one-to-one to the plurality of water cavities 21.

[0050] In this embodiment, in order to better circulate the cooling water in the water flow cavity 21, a plurality of first water flow grooves 51 are provided on one end surface of the first insert 5 close to the cavity 11. The plurality of first water flow grooves 51 are connected to the plurality of water flow cavities 21 one-to-one, so that the cooling water in the water flow channel 43 at one end of the water flow cavity 21 flows through the first water flow grooves 51 to the water flow channel 43 at the other end.

[0051] In this embodiment, the cooling system of the mold also includes a water flow pipe 7, and any two adjacent water flow chambers 21 are connected through the water flow pipe 7, so that the water flow chambers 21 are connected to each other, so that the circulating water circuit 3 only needs to be connected to any two of the water flow chambers 21 to complete the transportation and discharge of cooling water in multiple water flow chambers 21.

[0052] In this embodiment, the cooling system of the mold also includes a seal. The end face of the cavity 11 close to the opening has multiple annular grooves corresponding to the first water grooves 51. The seal is arranged in the annular grooves to improve the sealing performance between the first insert 5 and the cavity 11.

[0053] like Figure 5 As shown, in this embodiment, the cooling system of the mold also includes a second insert 6, which is connected to one end of the cavity 11. The second insert 6 has a plurality of second water grooves 61, and the second water grooves 61 are connected to the cooling pipe 22.

[0054] In this embodiment, in order to allow the cooling water in the cooling pipe 22 to circulate better, a second insert 6 is provided with a plurality of second water grooves 61 on one end face close to the cavity 11. The plurality of second water grooves 61 are connected to the plurality of cooling pipes 22 in a one-to-two manner, so that the cooling water in one of the two adjacent cooling pipes 22 flows to the other cooling pipe 22 through the second water grooves 61.

[0055] like Figures 3 to 5 As shown, in this embodiment, the water flow chamber 21 has a water flow section 211, which is arranged on the outer wall of the water flow chamber 21 away from the water barrier block 4, and the adjacent two cooling pipes 22 are connected through the water flow section 211.

[0056] In this embodiment, in order to facilitate the mutual communication between any two cooling pipes 22, two adjacent cooling pipes 22 are connected through a water flow section 211, and the water flow section 211 and the second water flow trough 61 are staggered with each other along the axial direction of the cavity 11, so that the cooling water of the two adjacent cooling pipes 22 flows through the second water flow trough 61 or the water flow section 211, so that the circulating water circuit 3 only needs to be connected with any two cooling pipes 22 to complete the transportation and discharge of cooling water in multiple cooling pipes 22.

[0057] like Figure 6 and Figure 7 As shown, in this embodiment, the first circulating water channel 31 includes a first water inlet channel 311 and a first water outlet channel 312, and the first water inlet channel 311 is connected to the first water outlet channel 312 through the first cooling water channel;

[0058] The second circulating water channel 323 includes a second water inlet channel 321 and a second water outlet channel 322 . The second water inlet channel 321 is connected to the second water outlet channel 322 through the second cooling water channel.

[0059] In this embodiment, a first circulating water channel 31 and a second circulating water channel 323 are provided to respectively transport cooling water to the first cooling water channel and the second cooling water channel, or to respectively discharge the cooling water in the first cooling water channel and the second cooling water channel, thereby facilitating the operator to control the opening or closing of the first cooling water channel or the second cooling water channel, thereby further facilitating the operator to regulate the temperature of different positions of the product.

[0060] In this embodiment, the specific working process of this application is as follows: the operator opens the first water inlet channel 311, and cooling water is transported from the first water inlet channel 311 to one of the water channels 43 in the water chamber 21. The cooling water then flows from the water channel 43 through the first water trough 51 to another water channel 43 in the same water chamber 21, and then flows through the water pipe 7 to the next water chamber 21. At this time, the cooling water continues to flow through the above-mentioned flow path and fills multiple water chambers 21 with cooling water. When the operator opens the first water outlet channel 312, the cooling water in the water chamber 21 that is finally filled with cooling water is discharged from the multiple water chambers 21 through the first water outlet channel 312. When the operator opens the second water inlet channel 321, cooling water is delivered from the second water inlet channel 321 to one of the cooling tubes 22. The cooling water then flows from that cooling tube 22 through the second water trough 61 to the adjacent cooling tube 22, and then through the water section 211 to the next cooling tube 22. At this point, the cooling water continues to flow through the aforementioned route, filling multiple cooling tubes 22. When the operator opens the second water outlet channel 322, the cooling water in the last cooling tube 22 to be filled with cooling water is discharged through the second water outlet channel 322, discharging the cooling water from the multiple cooling tubes 22.

[0061] The present invention also proposes a mold, which includes a cooling system for the mold. The specific structure of the cooling system of the mold refers to the above-mentioned embodiment.
