After the automobile seat frame is injection molded, it is usually necessary to cool the injection molded automobile seat frame. Most of the existing injection molds are equipped with a cooling water channel structure, and the distances between each part of the water channel in the cooling water channel structure and the wall of the product molding cavity are not equal, resulting in uneven cooling effect of the water channel on the product molding cavity, which can easily lead to poor product molding quality.

[0003] The prior art CN207841921U discloses an injection mold with a special-shaped water channel structure. By surrounding the water channel body on the outside of the product molding cavity wall, the water channel body can evenly cool the product molding cavity wall, shortening the cooling time of the water channel body on the product molding cavity wall, thereby reducing the possibility of mold sticking during product molding and improving product molding quality.

[0004] However, the above-mentioned injection mold is not provided with a water channel observation mechanism, resulting in that the staff cannot observe the water channel conditions in the mold in real time. As a result, when the water channel in the mold is blocked, the staff cannot check it in time, and thus the molding quality of the product cannot be guaranteed. Summary of the invention

[0030] The present invention provides an injection mold with a water flow observation mirror 103, including a mold body 101 and a water flow observation structure, the water flow observation structure includes a first observation tube 102, a water flow observation mirror 103, a second observation tube 104 and a limit member, the limit member includes a limit screw 105 and a limit nut 106.

[0031] In this embodiment, the molding cavity 107 is provided in the mold body 101, so that the automobile seat frame can be injection molded in the molding cavity 107. Afterwards, the water inlet 108, the cooling water path 110 and the water outlet 109 are provided below the molding cavity 107, so that the coolant can flow through the water inlet 108, the cooling water path 110 and the water outlet 109 in sequence, so as to realize cooling of the automobile seat frame injection molded in the molding cavity 107. 02 and the second observation tube 104 are connected to the water flow observation mirror 103, so that the staff can observe the water channel conditions in the mold body 101 in real time through the water flow observation mirror 103 to ensure that the cooling water channel 110 in the mold body 101 can always remain unobstructed, thereby ensuring the molding quality of the product, and solving the problem that the existing injection mold is not equipped with a water channel observation mechanism, resulting in the staff being unable to observe the water channel conditions in the mold in real time, so that when the water channel in the mold is not unobstructed, the staff cannot check it in time, and thus cannot ensure the molding quality of the product.

[0032] The mold body 101 is a one-time molding mechanism, having a molding cavity 107, a water inlet 108, a water outlet 109 and a cooling water channel 110, wherein the water inlet 108, the cooling water channel 110 and the water outlet 109 are sequentially connected, and the water inlet 108, the cooling water channel 110 and the water outlet 109 are all located below the molding cavity 107, the first observation tube 102 is connected to the water inlet 108, the second observation tube 104 is connected to the water outlet 109, and the first observation tube 102 and the second observation tube 104 are both connected to the water flow observation mirror 103, and since the water inlet 108, the cooling water channel 110 and the water outlet 109 are sequentially connected, the coolant can be sequentially in the water inlet 108, the cooling water channel 110 and the water outlet 109. Circulation is achieved to cool the automobile seat frame injection molded in the molding cavity 107. Since the first observation tube 102 and the second observation tube 104 are both connected to the water flow observation mirror 103, and the first observation tube 102 is connected to the water inlet 108, and the second observation tube 104 is connected to the water outlet 109, the coolant at the water outlet 109 can flow into the water flow observation mirror 103, and the coolant flowing into the water flow observation mirror 103 can flow into the water inlet 108, so as to achieve the circulation of the coolant, so that the staff can observe the water channel conditions in the mold body 101 in real time through the water flow observation mirror 103, so as to ensure that the cooling water channel 110 in the mold body 101 can be kept unobstructed at all times, thereby ensuring the molding quality of the product.

[0033] Secondly, there are two water inlets 108, two water outlets 109 and two cooling water channels 110. The two water inlets 108 are symmetrically arranged on the left and right sides of the mold body 101, and the two water outlets 109 are respectively located on the left and right sides of the mold body 101. The flow directions of the coolants in the two cooling water channels 110 are opposite, so that the two cooling water channels 110 can jointly cool the injection molded automobile seat frame in the molding cavity 107 to shorten the cooling time and improve the cooling efficiency.

[0034] Again, the mold body 101 further has a threaded hole 111 , in which a mounting bolt 112 is detachably provided. The mold body 101 is mounted on a work surface 113 by means of the mounting bolt 112 , thereby fixing the mold body 101 .

[0035] At the same time, the water flow observation mirror 103 is detachably connected to the first observation tube 102 and the second observation tube 104 to realize the disassembly and assembly of the water flow observation mirror 103. The surface mirror 114 of the water flow observation mirror 103 is made of transparent glass. By observing the water flow of the surface mirror 114 of the water flow observation mirror 103, the patency of the cooling water circuit 110 can be known. By disassembling and assembling the water flow observation mirror 103, when the surface mirror 114 of the water flow observation mirror 103 is dirty, the surface mirror 114 can be cleaned or replaced with a new water flow observation mirror 103.

[0036] In addition, sealing rings 115 are provided on both sides of the first observation tube 102 and the second observation tube 104, and the sealing rings 115 are used to seal the connection between the first observation tube 102 and the water inlet 108, the connection between the second observation tube 104 and the water outlet 109, and the connection between the water flow observation mirror 103 and the first observation tube 102 or the second observation tube 104.

[0037] Finally, the limiting screw 105 is arranged on a side of the mold body 101 close to the water flow observation mirror 103, the limiting nut 106 is detachably connected to the limiting screw 105, and is sleeved outside the limiting screw 105, the limiting nut 106 has an internal thread, and the limiting screw 105 has an external thread, the limiting nut 106 is threadedly connected to the limiting screw 105, so that the limiting nut 106 can move along the trajectory of the thread outside the limiting screw 105, so that the limiting nut 106 can be tightened or loosened outside the limiting screw 105, and then the water flow observation mirror 103 can be installed or disassembled outside the mold body 101.

[0038] When using an injection mold with a water flow observation mirror 103 of the present embodiment, the mounting plate of the water flow observation mirror 103 is passed through the limiting screw 105, and then the limiting nut 106 is placed outside the limiting screw 105, so that the limiting nut 106 can move along the trajectory of the thread outside the limiting screw 105, so that the limiting nut 106 can be tightened outside the limiting screw 105, thereby realizing the installation of the water flow observation mirror 103 outside the mold body 101. After the water flow observation mirror 103 is installed, the injection liquid is poured into the molding cavity 107, and the injection liquid is injection molded in the molding cavity 107 to obtain a car seat frame. After molding, the coolant is transmitted from the water inlet 108, so that the coolant can be sequentially inserted into the water inlet 108, the cooling water channel 110 and the The water flows in the water outlet 109 to cool the automobile seat frame injection molded in the molding cavity 107. During the circulation of the coolant, the water flow observation mirror 103 is connected at the water inlet 108 and the water outlet 109 through the first observation tube 102 and the second observation tube 104, so that the staff can observe the water channel conditions in the mold body 101 in real time through the mirror 114 of the water flow observation mirror 103 to ensure that the cooling water channel 110 in the mold body 101 can always remain unobstructed, thereby ensuring the molding quality of the product. This solves the technical problem that the existing injection mold is not equipped with a water channel observation mechanism, which makes it impossible for the staff to observe the water channel conditions in the mold in real time, so that when the water channel in the mold is not unobstructed, the staff cannot check it in time, and thus cannot ensure the molding quality of the product.
