DETAILED DESCRIPTION

[0020] The utility model will be further described below in combination with the drawings and embodiments. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be understood as the usual meanings by those skilled in the art to which the utility model belongs. The features mentioned above or the features mentioned in the specific examples can be combined arbitrarily, and these specific embodiments are only used to illustrate the utility model and not to limit the scope of the utility model.

[0021] Embodiment

[0022] As Figures 1-3 shown, the utility model provides a prevent automobile lift mould waterway backflow's block structure, including mould core 1, installation platform 2, backflow block slide 3 and cooling water subassembly 4. Backflow block slide 3 one end is connected with the installation groove 21 of installation platform 2, and its other end is connected with the limiting slot 11 of mould core 1. Backflow block slide 3 upper portion is equipped with cooling water chamber 31, and cooling water chamber 31 is communicated with the outlet tube 42 of cooling water subassembly 4, and the water inlet pipe 41 of outlet tube 42 inner sleeve is located inside cooling water chamber 31. Water inlet pipe 41 and outlet tube 42 all partially locate in the installation cavity 22 of installation platform 2, and water inlet pipe 41 is communicated with the water inlet nozzle 43 outside installation platform 2, and outlet tube 42 is communicated with the water outlet nozzle 44 outside installation platform 2.

[0023] Cooling water subassembly 4 and cooling water chamber 31 of backflow block slide 3 mutually cooperate, complete the cooling of the hole position in the product of mould core 1 forming, prevent product shrinkage deformation. The installation of backflow block slide 3 installation part 34 is in the installation groove 21 of installation platform 2, and is connected with the outlet tube 42 in installation platform 2 and backflow block slide 3 corresponding connection. The end of backflow block slide 3 away from installation platform 2 is connected with the limiting slot 11 of mould core 1, and the limiting slot 11 is set, and the position of backflow block slide 3 on mould core 1 is limited, and then cooling water chamber 31 is located at the hole position of the forming product.

[0024] As Figure 4 shown, backflow block slide 3 includes cooling water chamber 31, first limiting part 32, second limiting part 33 and installation part 34 sequentially arranged in a stepped manner from top to bottom, second limiting part 33 is connected with limiting slot 11, and installation part 34 is connected with installation groove 21. The structures of backflow block slide 3 are arranged in a stepped manner, which facilitates accurate installation of backflow block slide 3 on mould core 1, and cooling water chamber 31 is installed at the hole position of the forming product.

[0025] The end of cooling water chamber 31 away from outlet tube 42 is provided with a plug head 35, and the upper part of backflow block slide 3 is provided with a connecting cavity in communication with cooling water chamber 31. The plug head 35 prevents water in the cooling water chamber 31 from entering the forming product and the mould core 1. Cooling water enters the cooling water chamber 31 through the water inlet pipe 41 and then flows out of the cooling water chamber 31 through the outlet pipe 42, completing the circulation process of the cooling water. When the cooling water flows in the waterway, the plug head 35 acts as a barrier to ensure that the cooling water flows in the predetermined direction, avoiding backflow phenomenon, thereby ensuring the cooling effect of the forming product.

The sealing ring is arranged so that the cooling water can only flow out through the outlet pipe 42, and the cooling water is prevented from entering the connecting cavity and the mounting cavity 22, thereby ensuring the normal processing of the mold core 1.

[0027] The mounting table 2 is connected with one side of the mold core 1 through the backflow blocking slide block 3, and the connecting mode makes the backflow blocking slide block 3 more flexible to replace.

[0028] The length of the inlet pipe 41 is greater than that of the outlet pipe 42, which helps to ensure that the cooling water can fully enter the cooling water cavity 31 and improve the cooling effect.

[0029] Therefore, the backflow blocking slide block plays a barrier role, ensures the cooling water to flow in the predetermined direction, avoids the occurrence of the backflow phenomenon, and the cooling water can smoothly pass through the backflow blocking slide block to cool the product hole, thereby preventing the product from being deformed due to shrinkage.
