Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically a polyurethane door and window molding die. Background Technology

[0002] Polyurethane window and curtain wall systems, as a new type of window and door system, are characterized by high strength, non-deformation, and aging resistance. As the profiles for these systems, they require mold casting. However, molds made of other materials present various problems when selecting molds. Aluminum alloy, with its good plasticity, high strength, and resistance to oxidation, allows for better selection of molds for polyurethane window and curtain wall profiles. This improves the accuracy of the groove dimensions and the flatness of the profiles.

[0003] A search revealed a Chinese patent publication number: CN211807284U, which provides a molding die for polyurethane door and window curtain wall profiles. The die includes a first connecting piece, a second connecting piece, a third connecting piece, and a fourth connecting piece that are sequentially closed and connected. The interiors of the first connecting piece, the second connecting piece, the third connecting piece, and the fourth connecting piece form a cavity. A molding die for polyurethane door and window curtain wall profiles with the above structure has good plasticity, high strength, is not prone to oxidation, and can better guarantee the groove size and flatness of the polyurethane door and window curtain wall profiles.

[0004] Although the aforementioned patents can guarantee the groove size and flatness of polyurethane door and window curtain wall profiles, the aforementioned device still has the following problems: after the material cools and forms, the staff needs to manually open the mold. At the same time, due to the multi-piece mold, the manual mold opening is quite troublesome and increases the labor intensity of the staff to a certain extent. It also affects the processing speed of the workpiece. In view of the above, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0009] Preferably, the surface of the first threaded rod has two opposite threads starting from its center, and the interior of the slider is threadedly connected to the surface of the first threaded rod. The two sliders are respectively disposed on the two opposite threads on the surface of the first threaded rod.

[0010] Preferably, the interior of the second movable groove is rotatably connected to a second threaded rod, and the surface of the second threaded rod is also provided with two opposite threads starting from its center. The interior of the first movable frame is threadedly connected to the surface of the second threaded rod, and the two first movable frames are respectively disposed on the two opposite threads on the surface of the second threaded rod.

[0012] Preferably, a fan is provided inside the ventilation slot, a first air inlet is provided at the bottom of both the left and right molds, and a second air inlet is provided at the bottom of the lower mold, extending into the interior of the left and right molds.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This polyurethane door and window molding die, through the constraint of the first threaded rod in the first moving groove, can drive two sliders and two second moving frames to move relative to each other through two opposite threads, thereby realizing the opening of the upper and lower molds. The second motor drives the second threaded rod to rotate, and the second threaded rod, through the constraint of the second moving groove, can drive the two first moving frames to move relative to each other through two opposite threads, thereby realizing the opening of the left and right molds. This makes the mold opening of the device more convenient and, to a certain extent, makes it easier for workers to handle the molded polyurethane doors and windows.

[0015] 2. This polyurethane door and window molding die allows air from the external environment to enter the interior of the groove via a fan. Simultaneously, the inclined surface inside the groove concentrates the airflow towards the die, ensuring that the airflow overflowing from the groove adheres as closely as possible to the die. This facilitates heat dissipation for the die. Through the first and second air inlets, the airflow enters the interior of the left and right die side plates, further accelerating heat dissipation and speeding up the cooling and molding of the material inside the die.

[0022] Furthermore, a first threaded rod 10 is rotatably connected inside the first moving groove 12, and a first motor 11 is fixedly connected to the top of the support plate 2. The first motor 11 is a forward and reverse motor, which will not be elaborated on here. The output end of the first motor 11 rotates through the top of the support plate 2 and extends into the interior of the first moving groove 12. The output end of the first motor 11 is fixedly connected to the top of the first threaded rod 10.

[0023] Furthermore, the surface of the first threaded rod 10 is provided with two opposite threads starting from its center. The interior of the slider 9 is threadedly connected to the surface of the first threaded rod 10. The two sliders 9 are respectively set on the two opposite threads on the surface of the first threaded rod 10. The first threaded rod 10 is restricted by the first moving groove 12. Through the two opposite threads, the two sliders 9 and the two second moving frames 8 can be driven to move relative to each other, and the upper mold 5 and the lower mold 6 can be opened.

[0024] Furthermore, a second threaded rod 15 is rotatably connected inside the second moving groove 13. The surface of the second threaded rod 15 is also provided with two opposite threads starting from its center. The interior of the first moving frame 7 is threadedly connected to the surface of the second threaded rod 15. The two first moving frames 7 are respectively set on the two opposite threads on the surface of the second threaded rod 15. The second threaded rod 15 is restricted by the second moving groove 13.

[0029] Working principle: For this type of polyurethane door and window molding die, a sealed mold is first formed by the left mold 3, right mold 4, upper mold 5, and lower mold 6, allowing workers to inject polyurethane door and window materials. The fan 17 allows air from the external environment to enter the interior of the groove 18. Simultaneously, the inclined surface inside the groove 18 concentrates the airflow towards the mold, ensuring that any overflowing airflow adheres as closely as possible to the mold. This facilitates heat dissipation and accelerates the cooling and molding of the material inside the mold. Once the workpiece is formed, the first motor 11 drives the first threaded rod 1... The first threaded rod 10 rotates, and the first threaded rod 10 is restricted by the first moving groove 12. Through two opposite threads, it can drive the two sliders 9 and the two second moving frames 8 to move relative to each other, and realize the opening of the upper mold 5 and the lower mold 6. The second motor 14 drives the second threaded rod 15 to rotate. The second threaded rod 15 is restricted by the second moving groove 13.
