Description

Technical Field

[0001] The utility model particularly relates to a hot extrusion die for producing heat-insulating doors and windows with six holes and two outlets. Background Art

[0002] Insulated door and window aluminum profiles are an aluminum alloy material with excellent thermal insulation properties. They are also called thermally insulated aluminum. They are made by adding low thermal conductivity insulators, such as hard plastic or nylon, in the middle of the aluminum alloy profiles to cut off the heat conduction between the metals, thereby reducing the overall heat transfer efficiency and improving the thermal insulation performance of doors and windows. This helps reduce the frequency of use of heating and cooling air conditioners, thereby achieving energy conservation and emission reduction effects. They are widely used in modern buildings to improve energy efficiency and living comfort.

[0003] Currently, thermal insulation doors and windows are all produced using hot extrusion dies. However, traditional hot extrusion dies can only produce one product at a time, and the mold core is unevenly stressed due to the impact of the aluminum flow, which can easily cause deflection. This leads to dark shadows on the surface of the thermal insulation doors and windows during molding, and the quality does not meet the standards.

[0004] Therefore, it is necessary to invent a six-hole double-outlet hot extrusion die for producing heat-insulating doors and windows to solve the above problems. Utility Model Content

[0005] (1) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes a six-hole double-outlet hot extrusion die for producing heat-insulating doors and windows. By setting six diversion holes in groups of three and three, and setting the mold core at the center of the triangle formed by connecting the midpoints of the three diversion holes, the impact force of the aluminum flow on the entire mold core is distributed more evenly, ensuring that the mold core is relatively stable and not prone to deflection, and maintaining the stability of the aluminum flow rate. The two cavities are distributed one positive and one negative, so that the two mold cores are subjected to balanced tension when promoting the formation of heat-insulating doors and windows, thereby avoiding the appearance of dark shadows on the surface of the heat-insulating doors and windows during forming. The design of the two cavities allows the mold body to have two outlets in one mold, which doubles the single-shift output of the mold body and improves the production efficiency of heat-insulating doors and windows.

[0007] (2) Technical solution

[0008] In order to achieve the above-mentioned object, the utility model provides the following technical solutions: a six-hole double-outlet hot extrusion die for producing heat-insulating doors and windows, comprising an upper die and a lower die located at the bottom of the upper die;

[0009] A diverter bridge is provided inside the upper mold, and six diverter holes are spaced apart by the diverter bridge inside the upper mold. The diverter holes are symmetrically distributed in groups of three about the center of the upper mold, and the distance between the midpoints of any two diverter holes in each group is equal;

[0010] The lower mold includes two welding chambers opened on the top of the lower mold, and two cavities opened inside the lower mold and respectively connected to the two welding chambers, and the two cavities are distributed one in front and one in back;

[0011] The diverter bridge is located below each group of diverter holes and is connected to a mold core for being inserted into the corresponding mold cavity, so that the heat-insulating door window can be produced by six-hole double-outlet hot extrusion.

[0012] Preferably, the two welding chambers are symmetrically distributed about the center of the lower mold, and the welding chamber is in a convex shape as a whole.

[0013] Preferably, two discharge holes are provided at the bottom of the lower mold, and the two discharge holes are respectively connected to the mold cavity above them.

[0014] Preferably, the two discharge holes are both arranged in a stepped shape.

[0015] Preferably, the upper mold and the lower mold are both made of H13 mold steel, and are both disc-shaped.

[0016] Preferably, the upper mold and the lower mold are fastened to each other through fasteners to form a mold body.

[0017] Compared with the prior art, the beneficial effects of the above technical solution of the utility model are:

[0018] The utility model sets six diversion holes in groups of three, and the three diversion holes in each group are distributed in a triangular shape, and the mold core is set at the center of the triangle, so that the mold core can be fully and directly impacted by the aluminum flow flowing out of the three diversion holes, ensuring sufficient feeding. At the same time, the principle of stability of the triangle is utilized to make the impact force of the aluminum flow on the mold core as a whole more uniform, ensuring that the mold core is relatively stable and not prone to deflection, and maintaining the stability of the aluminum flow rate. The distribution of the two cavities, one positive and one negative, makes the two mold cores receive balanced tension when forming the heat insulation door window, thereby further reducing the phenomenon of the mold core deflecting due to uneven force, thereby avoiding the appearance of dark shadows on the surface of the heat insulation door window during forming. The design of the two cavities allows the mold body to also produce two products from one mold. Compared with the traditional single-cavity design, this mold body not only has good molding quality of heat insulation door windows, but also doubles the output per shift, thereby improving the production efficiency of heat insulation door windows.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The utility model provides Figure 1-5 A six-hole double-outlet hot extrusion die for producing heat-insulating doors and windows shown in FIG. includes an upper die 1 and a lower die 2 located at the bottom of the upper die 1;

[0029] A diverter bridge 11 is provided inside the upper mold 1. Six diverter holes 12 are spaced apart by the diverter bridge 11. The diverter holes 12 are symmetrically distributed in groups of three about the center of the upper mold 1, and the distance between the midpoints of any two diverter holes 12 in each group is equal.

[0030] The lower mold 2 includes two welding chambers 21 opened at the top of the lower mold 2, and two cavities 22 opened inside the lower mold 2 and respectively connected to the two welding chambers 21, and the two cavities 22 are distributed one front and one back;

[0031] The diverter bridge 11 is located below each group of diverter holes 12 and is connected to a mold core 13 for being inserted into the corresponding mold cavity 22, so that the heat-insulating door window can be produced by six-hole double-outlet hot extrusion.

[0032] In one embodiment, the two welding chambers 21 are symmetrically distributed about the center of the lower mold 2, and the welding chamber 21 is convex in shape as a whole, which is used to cooperate with the diversion holes 12 distributed in a triangular shape, so that the aluminum flow can transition more smoothly to the inside of the welding chamber 21. Two discharge holes 23 are opened at the bottom of the lower mold 2, and the two discharge holes 23 are respectively connected to the cavity 22 above them. The two discharge holes 23 are both arranged in a stepped shape to facilitate the extrusion of the aluminum profile after forming, thereby ensuring the integrity of the aluminum profile surface.

[0033] In one embodiment, the upper mold 1 and the lower mold 2 are both made of H13 mold steel, and the upper mold 1 and the lower mold 2 are both disc-shaped, so that the upper mold 1 and the lower mold 2 have high strength and long service life. The upper mold 1 and the lower mold 2 are tightly matched with each other to form a mold body through fasteners. Specifically, the fasteners are set as pins or bolts to facilitate the staff to assemble the mold body, and the mold body as a whole is disc-shaped, which is convenient for the staff to use the mold body.

[0034] The specific implementation method is as follows: When the present invention is in use, aluminum flows through the top of the six diversion holes 12 and flows into the interior of the upper mold 1. At this time, the aluminum flow is evenly divided into six streams by the diversion holes 12, so that the impact force of the aluminum flow is dispersed, thereby reducing the impact force on the upper mold 1, indirectly ensuring the stability of the mold core 13. Further, the aluminum flow flows downward into the welding chamber 21, and then flows into the gap between the mold core 13 and the cavity 22. At this time, under the extrusion of the cavity 22, the aluminum flow is formed into an aluminum profile for insulating doors and windows, and further discharged downward through the discharge hole 23, thereby completing the hot extrusion production of insulating doors and windows;

[0035] Specifically, when the aluminum flow flows inside the upper mold 1, the distance between the midpoints of any two diversion holes 12 in each group is equal, that is, the three diversion holes 12 in each group are distributed in a triangular shape, so that the mold core 13 below each group of diversion holes 12 is located at the center of the above triangle. The mold core 13 can be fully and directly impacted by the aluminum flow flowing out of the three diversion holes 12, ensuring sufficient material supply. At the same time, the impact force of the aluminum flow on the mold core 13 as a whole is more evenly distributed due to the stability principle of the triangle, making the mold core 13 relatively stable and not prone to deflection, maintaining a stable aluminum flow rate, and avoiding the appearance of dark shadows on the surface of the insulating door and window during molding;

[0036] The two cavities 22 are arranged in a positive and negative pattern, so that the two thermal insulation doors and windows are also formed in a positive and negative pattern during molding. This ensures that the tension on the two mold cores 13 is balanced when molding the thermal insulation doors and windows. The overall force on the mold body is also relatively uniform, thus further reducing the phenomenon of the mold core 13 swinging due to uneven force. The design of two cavities 22 allows the mold body to produce two products from one mold. Compared with the traditional single-cavity 22 design, the single-shift output of this mold is doubled, thereby improving the production efficiency of thermal insulation doors and windows.

[0037] This embodiment specifically solves the problem in the prior art that the current hot extrusion mold can only produce one mold and one output when producing thermal insulation doors and windows, and the mold core 13 is easily deflected due to the impact of the aluminum flow, which leads to uneven wall thickness, dark shadows on the surface, and substandard quality of the thermal insulation doors and windows during molding.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
