Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1 to 9 As shown, this embodiment discloses an insert-type handle preform mold lip, including two mirror-symmetrically arranged half-mold lip components 1. Each half-mold lip component 1 includes a half-mold lip base 2 and a half-mold lip insert 3. The inner side of the half-mold lip insert 3 is provided with a half-handle forming position 31 for defining part of the handle forming and a first half-preform forming position 38 for defining part of the preform body forming. The half-handle forming position 31 communicates with the first half-preform forming position 38. The interior of the half-mold lip insert 3 is provided with an insert cooling water channel 32 for at least cooling the half-handle forming position 31. The insert cooling water channel 32 can also simultaneously cool the half-handle forming position 31. The hand forming position 31 and the first half-preform forming position 38 are provided with cooling; the inner side of the half-mold lip base 2 is provided with a second half-preform forming position 21 for defining part of the preform forming and a base recess 22 for connecting the half-mold lip insert 3. The interior of the half-mold lip base 2 is provided with a base cooling water channel for at least providing cooling for the second half-preform forming position 21. The half-mold lip insert 3 is adaptedly provided in the base recess 22. The first half-preform forming position 38 is connected to the second half-preform forming position 21 and forms a half-preform forming position. The base cooling water channel is connected to the insert cooling water channel 32. In this embodiment, the mold lip is processed by setting the half mold lip component 1 as two workpieces: the half mold lip base 2 and the half mold lip insert 3. Correspondingly, the mold lip cooling water channel is also set as the base cooling water channel and the insert cooling water channel 32, which are processed in the two workpieces respectively. Then, the base cooling water channel and the insert cooling water channel 32 are connected by combining the half mold lip base 2 and the half mold lip insert 3 to form the mold lip cooling water channel. This can effectively reduce the processing difficulty of the mold lip cooling water channel, make the whole processing process simpler and more convenient, and improve processing efficiency and processing accuracy.

[0019] In this embodiment, the substrate cooling water channel includes a separate substrate inflow water channel 23 and a substrate outlet water channel 24. The semi-die lip substrate 2 is provided with a substrate inlet 25 for supplying cooling medium to the substrate inflow water channel 23 and a substrate outlet 26 for supplying cooling medium to the substrate outlet water channel 24. The substrate inflow water channel 23, the insert cooling water channel 32, and the substrate outlet water channel 24 are sequentially connected to form the die lip cooling water channel. The substrate inflow water channel 23 includes a substrate inlet water channel 236 and a substrate cooling water channel 237. The insert cooling water channel 32 includes an insert cooling water channel and an insert outlet water channel. The substrate cooling water channel 237 is arranged at least along the second half-preform forming position 21, and the insert cooling water channel is arranged along the half-handle forming position 31 and the first half-preform forming position 38. The substrate inlet water channel 236, the substrate cooling water channel 237, the insert cooling water channel, the insert outlet water channel, and the substrate outlet water channel 24 are sequentially connected. The substrate cooling water circuit adopts a series cooling water circuit or a combination of series and parallel cooling water circuits.

[0020] In this embodiment, the inner side of the half-mold lip base 2 is also provided with a first half-formed blank opening position 27 for defining part of the blank opening forming, and the base cooling water channel also provides cooling for the first half-formed blank opening position 27; the inner side of the half-mold lip insert 3 is also provided with a second half-formed blank opening position 33 for defining part of the blank opening forming, and the insert cooling water channel 32 also provides cooling for the second half-formed blank opening position 33; the half-mold lip base 2 and the half-mold lip insert 3 are combined to make the first half-formed blank opening position 27 and the second half-formed blank opening position 33 engage to define half of the blank opening forming.

[0021] In this embodiment, the substrate inflow water channel 23 includes an inlet channel 231, a first cooling water channel 232, and a second cooling water channel 233. The inlet channel 231 is used to introduce the cooling medium, the first cooling water channel 232 is used to provide cooling for the second half preform forming position 21, and the second cooling water channel 233 is used to provide cooling for the first half preform opening forming position 27. The substrate outlet water channel 24 includes an outlet channel 241, which is used to draw out the cooling medium. The insert cooling water channel 32 includes a third cooling water channel 321 and a fourth cooling water channel 322. The third cooling water channel 321 is used to provide cooling for the second half-preform forming position 33, and the fourth cooling water channel 322 is used to provide cooling for the half-handle forming position 31. The first cooling water channel 232, the second cooling water channel 233, the third cooling water channel 321, and the fourth cooling water channel 322 are respectively arranged along the second half-preform forming position 21, the first half-preform forming position 27, the second half-preform forming position 33, and the half-handle forming position 31. The water inlet channel 231, the first cooling water channel 232, the second cooling water channel 233, the third cooling water channel 321, the fourth cooling water channel 322, and the water outlet channel 241 are connected in sequence.

[0022] In this embodiment, the substrate inflow water path 23 further includes an inlet connecting water channel 234, through which the inlet channel 231 and the first cooling water channel 232 are connected. By setting the inlet connecting water channel 234, the arrangement of the inlet channel 231 and the first cooling water channel 232 in the half-mold lip substrate 2 becomes more flexible. The two do not need to be directly connected, so they are not limited by the connection structure. The opening of the inlet channel 231 and the first cooling water channel 232 can be designed according to the cooling requirements and the internal structure of the half-mold lip substrate 2, and then connected by the inlet connecting water channel 234.

[0023] In this embodiment, the number of first cooling channels 232 can be set according to the size of the cooling range. When the second half of the preform forming position 21 is large, more than two first cooling channels 232 can be set in the half mold lip base 2. The base inflow water channel 23 also includes a branch channel 235. The inlet connecting channel 234 is connected to each of the first cooling channels 232 through the branch channel 235. The cooling medium in the inlet connecting channel 234 is distributed to each of the first cooling channels 232 through the branch channel 235, thereby improving the cooling effect and cooling uniformity of the second half of the preform forming position 21, which is beneficial to the forming of the preform body.

[0024] Correspondingly, the number of second cooling channels 233 can be set according to the size of the cooling range. When the first half-formed blank opening 27 is large, two or more second cooling channels 233 can be set in the half-die lip base 2. Each first cooling channel 232 is connected to each second cooling channel 233, so that the cooling medium in each first cooling channel 232 is distributed to each second cooling channel 233, thereby improving the cooling effect and cooling uniformity of the first half-formed blank opening 27, which is beneficial to the forming of the blank opening. The number of third cooling channels 321 is the same as the number of second cooling channels 233, and the third cooling channels 321 are connected to the second cooling channels 233 one by one. This ensures that the cooling effect of the second half-formed blank opening 33 is consistent with the cooling effect of the first half-formed blank opening 27, guaranteeing the consistency of blank opening forming. When there are two or more third cooling channels 321, the insert cooling channel 32 also includes a first transition connecting channel 323. Each third cooling channel 321 is connected to the fourth cooling channel 322 through the first transition connecting channel 323. The cooling medium in each third cooling channel 321 flows into the first transition connecting channel 323 and then into the fourth cooling channel 322, thereby better cooling the half handle forming position 31.

[0025] In this embodiment, the insert cooling water channel 32 further includes an insert water outlet channel 324, and the base water outlet channel 24 further includes a water outlet connecting channel 242. The fourth cooling water channel 322 is connected to the water outlet channel 241 through the insert water outlet channel 324 and the water outlet connecting channel 242. By setting the insert water outlet channel 324 and the water outlet connecting channel 242, the cooling medium that has flowed through the half mold lip base 2 and the half mold lip insert 3 to complete the cooling can be flexibly guided to the water outlet channel 241, thereby improving the flexibility of the cooling water channel setting.

[0026] In summary, the flow path of the cooling medium in the half-die lip component 1 is as follows: base water inlet 25 → water inlet channel 231 → water inlet connecting channel 234 → branch channel 235 → first cooling channel 232 → second cooling channel 233 → third cooling channel 321 → first transition connecting channel 323 → fourth cooling channel 322 → insert water outlet channel 324 → water outlet connecting channel 242 → water outlet channel 241 → base water outlet 26.

[0027] In this embodiment, the water inlet channel 231 and the water inlet connecting channel 234 constitute the base water inlet channel 236; the branch channel 235, the first cooling channel 232 and the second cooling channel 233 constitute the base cooling channel 237; and the third cooling channel 321, the fourth cooling channel 322 and the first transition connecting channel 323 constitute the insert cooling channel.

[0028] In this embodiment, the half-mold lip insert 3 can also be configured as a structure formed by combining two workpieces. The half-mold lip insert 3 includes an insert base 39 and a half-handle forming insert 30. The insert base 39 has an insert parting surface recess on its inner side. The half-handle forming insert 30 is configured in the insert parting surface recess to form a half-handle forming position 31.

[0050] In a preferred embodiment, the first water outlet connecting channel 2421 is processed radially from the outer peripheral surface of the semi-substrate disk 28 toward the recessed part 22 of the substrate, and the opening formed on the outer peripheral surface of the semi-substrate disk 28 is sealed with a plug to form the second water outlet connecting channel 2422.

[0051] In a preferred embodiment, the water outlet channel 241 is formed by processing the second water outlet connecting channel 2422 axially downward from the upper end face of the semi-substrate plate 28; the opening formed by processing the water outlet channel 241 on the upper end face of the semi-substrate plate 28 is the substrate water outlet 26.

[0052] In addition, a first sealing ring groove 291 is provided on the outer periphery of the opening formed by machining the third cooling section 2333 on the recessed surface of the first semi-cylinder 29; a sealing ring is provided in the first sealing ring groove 291 to seal the connection between the third cooling section 2333 and the third cooling water channel 321, effectively preventing water leakage at the water channel connection between the semi-mold lip base 2 and the semi-mold lip insert 3.

[0053] In addition, a second sealing ring groove 341 is provided on the outer periphery of the opening formed by the third transition section 3243 on the outer side of the semi-insertion plate 34; a sealing ring is provided in the second sealing ring groove 341 to seal the connection between the first water outlet connecting channel 2421 of the third transition section 3243, effectively preventing water leakage at the water channel connection between the semi-mold lip base 2 and the semi-mold lip insert 3.
