[0002] The automotive air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle. The air conditioning ducts are responsible for connecting to the various air conditioning vents inside the vehicle.

[0003] like Figure 1 As shown, the air conditioning duct in the background art has left and right ventilation openings, and a connecting part with two through square openings and one side square opening in the middle. The air conditioning duct has a multi-opening structure. This complex structure is difficult to form in one go during the traditional mold forming process. It usually requires multiple processing or complex mold design, which increases the complexity of forming and production costs. At the same time, the existing air conditioning duct structure is large in size, and the complex mold structure is difficult to cool. Traditional molds have the problem of local overheating, resulting in deformation or inaccurate dimensions of the formed duct. After forming, traditional molds usually require cutting the edges of the duct, especially the edges of the openings. Burrs or dimensional deviations are easy to occur during the later processing, affecting the sealing and appearance quality of the duct. Those skilled in the art urgently need to solve the above technical problems. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figure 1-6 As shown, a quick-forming air conditioning duct processing mold includes a left template 1 and a right template 2. After the left template 1 and the right template 2 are closed, a mold cavity with an air conditioning duct is formed.

[0038] The left template 1 has a left mold cavity 11 inside. Left mold inserts 3 are installed at both ends of the left mold cavity 11. A left insert cavity 31 communicating with the left mold cavity 11 is opened in the left mold insert 3. A left flange 32 is formed at the contact end between the left insert cavity 31 and the left mold cavity 11. The left flange 32 is directly opposite the edge of the air conditioning duct so as to form a cutting surface on the edge of the air conditioning duct after blow molding.

[0039] The right template 2 has a right mold cavity 21 that matches the left mold cavity 11. Right mold inserts 4 that match the left mold insert 3 are provided at both ends of the right mold cavity 21. A right insert cavity 41 that communicates with the right mold cavity 21 is provided in the right mold insert 4. A right flange 42 is formed at the contact end between the right insert cavity 41 and the right mold cavity 21. The right flange 42 faces the edge of the air conditioning duct so as to form a cutting surface on the edge of the air conditioning duct after blow molding.

[0040] A plurality of first cooling water holes 12 are evenly distributed on the left template 1 along the length direction of the left model cavity 11. The first cooling water holes 12 are arranged close to the left model cavity 11, and each of the first cooling water holes 12 is arranged through the width direction of the left template 1.

[0041] A plurality of second cooling water holes 22 are evenly distributed on the right template 2 along the length direction of the right model cavity 21. The second cooling water holes 22 are arranged close to the right model cavity 21, and each of the second cooling water holes 22 is arranged through the width direction of the right template 2.

[0042] The working principle and beneficial effects of the above embodiments are as follows:

[0043] This utility model discloses a quick-setting air conditioning duct processing mold. After the left mold plate 1 and the right mold plate 2 are closed, the left mold cavity 11 and the right mold cavity 21 together form a complete mold cavity for the air conditioning duct. The left mold insert 3 and the right mold insert 4 are respectively embedded into the two ends of the left and right mold plates. The insert cavities (31, 41) are connected to the main mold cavity. The left flange 32 and the right flange 42 are tightly joined when the mold is closed to form a sharp cutting edge. During the blow molding process, the plastic is squeezed into the insert cavities (31, 41), and the excess material is cut off at the flanges (32, 42), while forming a flat flange structure at the end of the air conditioning duct.

[0044] The first cooling water hole 12 and the second cooling water hole 22 of this utility model are evenly distributed along the length of the main cavity and close to the cavity wall. The circulating cooling water balances the heat during the molding of the air conditioning duct, shortens the cooling time, prevents deformation, and ensures the dimensional stability of the air conditioning duct.

[0045] This utility model discloses a rapid-forming air conditioning duct processing mold, which adopts an integrated molding process and integrates the flange part through the insert design. The flange part is precisely aligned with the mold cavity, ensuring that the edge of the air conditioning duct is cut flat and the sealing surface is of high quality, reducing the risk of leakage during the later assembly of the air conditioning duct. This processing mold rapidly shapes, reduces energy consumption, improves production efficiency, ensures production quality, and is suitable for mass production.

[0046] In one embodiment,

[0047] like Figure 7 As shown, a set of first surplus material grooves 13 and a set of overflow grooves 14 are symmetrically provided in the middle of the left model cavity 11. A 1mm wide left groove is provided at the opening of the first surplus material groove 13 and the overflow groove 14.

[0048] In one embodiment,

[0049] like Figure 8As shown, a set of second surplus material grooves 23 matching the first surplus material groove 13 are symmetrically opened in the middle of the right model cavity 21, forming a double-sided opening structure of the air conditioning duct. A 1mm wide right groove is opened at the opening of the second surplus material groove 23. The design of the left and right grooves makes the groove edge of the formed air conditioning duct and the surplus material form a cutting surface.

[0050] The overflow trough 14 corresponds to the right mold cavity 21, forming an opening structure on one side of the air conditioning duct;

[0051] When the mold is closed, the 1mm wide left / right grooves form a shearing blade, creating a smooth cutting groove between the molded air conditioning duct and the excess plastic. After the mold is opened, the molded air conditioning duct and the excess material are automatically separated, allowing for quick removal of the excess material. Only simple cleaning of the overflow groove is required.

[0052] In one embodiment,

[0053] Multiple first air holes 15 are provided inside the left model cavity 11, and multiple second air holes 24 are provided inside the right model cavity 21. The first air holes 15 and the second air holes 24 correspond to each other.

[0054] The air holes (15, 24) are arranged linearly to ensure uniform air pressure distribution during blow molding. After the mold is closed, high-pressure gas is injected simultaneously through the first air hole 15 and the second air hole 24 to push the plastic to fit evenly into the mold cavity. The symmetrical air blowing design can balance the pressure and prevent uneven wall thickness caused by unilateral force. After blow molding is completed, the gas is rapidly cooled through the first cooling water hole 12 and the second cooling water hole 22. The gas is continuously pressurized for a short period of time to prevent shrinkage and deformation.

[0055] In one embodiment,

[0056] The aforementioned left mold insert 3 is locked inside the left mold cavity 11 by bolts, and the aforementioned right mold insert 4 is locked inside the right mold cavity 21 by bolts, which facilitates maintenance and replacement;

[0057] The detachable design of the left mold insert 3 and the right mold insert 4 facilitates the processing of the left flange 32 and the right flange 42.

[0058] In one embodiment,

[0059] It also includes a guide device 5, which is arranged between the left template 1 and the right template 2. It includes multiple sets of guide pillars 51 and their respective matching guide sleeves 52. The guide pillars 51 are arranged around the left template 1, and the guide sleeves 52 associated with each guide pillar 51 are set at the corresponding positions of the right template 2; thereby improving the mold closing accuracy.

[0060] In one embodiment,

[0061] The aforementioned guide device 5 also includes a limiting protrusion 53 disposed on both sides of the middle of the left template 1, and a limiting groove 54 disposed on the right template 2 and matching the limiting protrusion 53. Both the limiting protrusion 53 and the limiting groove 54 are provided with inclined guide surfaces; the inclined surfaces of the limiting protrusion 53 and the limiting groove 54 guide the fine-tuning positioning.

[0062] In summary:

[0063] This utility model provides a quick-setting air conditioning duct processing mold. The left and right templates are closed together to form a complete mold cavity for the air conditioning duct. The insert cavity is connected to the main mold cavity. The flanged part is tightly joined when the mold is closed to form a sharp cutting edge. Excess material is cut off at the flanged part to form a flat flanged structure at the end of the air conditioning duct.

[0064] This utility model designs grooves of equal width at the openings of the waste material groove and the overflow groove to form an opening structure for the air conditioning duct. At the same time, the grooves form a shearing blade for the air conditioning duct. After the mold is opened, the formed duct and the waste material are automatically separated to form a flat groove.

[0065] The first and second cooling water holes of this invention are evenly distributed along the length of the main cavity and close to the cavity wall. The circulating cooling water balances the heat during the molding of the air conditioning duct, shortens the cooling time, prevents deformation, and ensures the dimensional stability of the air conditioning duct.
