Description

Technical Field

[0001] The utility model relates to the technical field of three-way pipe production, in particular to a three-way pipe production and forming device. Background Art

[0002] Plastic tee pipes are usually formed by injection molding equipment during production, and a cooling mechanism is usually provided to accelerate cooling and shaping in order to increase the molding speed. The Chinese patent authorization number CN220163107U discloses a tee pipe fitting injection molding device. Although the device is provided with a mounting mechanism to replace the inner mold core provided on the mounting plate, thereby changing the diameter of the inner mold core, so that when the inner mold core cooperates with injection mold A and injection mold B for injection molding, the thickness of the manufactured tee pipe fitting will also change, but the mold base needs to wait for the internal plastic to cool down before molding after injection molding. Although the cold air entering the concave groove can have a certain cooling effect, the concave groove can only cool the mold, and then the mold cools the outer wall of the tee pipe. The slow cooling from the outside to the inside causes the inner wall of the tee pipe to cool slowly, which in turn causes the cooling molding time to be extended. Utility Model Content

The mold core is opened at the top and bottom of the connection hole, the module is opened at the top and bottom, and the injection holes are opened on the surface of the first mold base and the second mold base.

[0005] Preferably, three modules are provided, the interior of the three modules is a hollow structure, and a guide plate is embedded in the module. There is a gap between one end of the guide plate and the inner wall of the module. The coolant flows left and right through the guide plate inside the module, thereby extending the travel of the coolant inside the module.

[0006] Preferably, the interior of the mold core is a hollow structure, and fins are welded inside the mold core. There are multiple fins, and the fins are distributed in a straight line with equal spacing. Heat is exchanged between the fins and the coolant inside the mold core, which is beneficial to increase the contact area between the mold core and the cooling water in a limited space, thereby improving the heat exchange efficiency.

[0007] Preferably, the fins are made of a copper-aluminum composite material, and two connecting holes are provided between two adjacent fins, respectively located at the top and bottom of the mold core, so as to facilitate the coolant to evenly contact and exchange heat with both sides of the fins.

[0008] Preferably, four positioning pins are embedded in one side of the first mold base, and the positioning pins are inserted into the hole grooves on one side of the second mold base. The positioning pins are used to facilitate accurate docking of the two mold bases to avoid misalignment and the formation of unqualified products.

[0009] Preferably, both sides of the first mold base and the second mold base are threadedly connected with fixing screws, and one end of the fixing screws abuts against both sides of the mold core. By loosening the fixing screws, the mold cores inside the first mold base and the second mold base can be removed, which is convenient for replacing mold cores of different models for molding.

[0010] The utility model provides a three-way pipe production and forming device. It has the following beneficial effects:

[0011] (1) A three-way pipe production and molding device. When the device is in use, coolant is injected through the connecting pipe at the top of the first mold base and the second mold base. The low-temperature coolant can enter the first mold base and the second mold base, and then enter the mold core through the connecting hole, which is beneficial to cooling the mold core, thereby quickly cooling and shaping the outer wall of the three-way pipe. At the same time, another cooling liquid enters the module through the connecting port. The cooling liquid flows left and right through the guide plate inside the module to achieve cooling of the module. Then, the module can cool the inner wall of the three-way pipe at the same time, which is beneficial to cooling and shaping the inside and outside of the three-way pipe at the same time, greatly reducing the molding time of the three-way pipe.

[0012] (2) The three-way tube production and molding device has a plurality of fins arranged at equal intervals inside the mold core, so that the three-way tube can transfer heat through the mold core to the fins, and then exchange heat with the coolant inside the mold core through the fins, which is beneficial to increase the contact area between the mold core and the cooling water in a limited space, thereby improving the heat exchange efficiency, and further facilitating the molding speed.

[0013] Thus, the problem that the existing shaping device can only perform cooling and shaping from the outside to the inside, resulting in a slow cooling speed of the inner wall of the three-way pipe and prolonged shaping time of the inner wall is solved. BRIEF DESCRIPTION OF THE DRAWINGS
