[0002] The mold is an indispensable and important tool in injection molding. Injection molding is a processing method in which hot molten plastic material is injected into a closed cavity of the desired shape in the mold at high speed, and the plastic material is cooled and solidified, and the mold is opened to eject the solidified plastic product to obtain a molded product. Since the injection molding processing method has the characteristics of low molding cost, short molding cycle, simple molding process and easy molding of plastic products with complex shapes, it is widely used in the application field of plastic products. With the continuous development of industry and the continuous innovation of products, its structure is becoming more and more complex accordingly. In plastic products, there are basically more or less internal undercut structures, and this kind of internal undercut generally adopts an inclined ejector. In traditional molds, when a large-angle inclined ejector is required, the ejection is not smooth due to the large angle of the inclined ejector, and it is easy to get stuck or break, which seriously affects the efficiency and quality of mold molding.

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0020] The technical solution specifically implemented in this utility model is:
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a tilting lift assembly for an injection mold includes a tilting lift 1, a tilting lift seat 2, a slider, a drag rod 3, and a reinforcing rod 4;
[0022] The slider is slidably arranged in the inclined top seat 2, and an inclined guide hole is provided on the slider;
[0023] The reinforcing rod 4 is movably inserted into the oblique guide hole, the top end of the reinforcing rod 4 is connected to an upper fixing block 5, and the bottom end of the reinforcing rod 4 is connected to a lower fixing block 6;
[0024] The bottom end of the drag rod 3 is fixedly connected to the slider, and the bottom end of the drag rod 3 extends to the bottom of the inclined top seat 2 and is connected to the mold water transfer block 7; the mold water transfer block 7 is used to connect the mold water cooling system to cool the mold and shorten the injection cycle.
[0025] The inclined roof 1 is fixedly connected to the top end of the towing rod 3 .
[0026] By adopting the above scheme, when the inclined ejector assembly for an injection mold of the utility model is used, the mold is opened, and the ejection mechanism acts on the inclined ejector seat 2, so that the inclined ejector seat 2 moves along the reinforcing rod 4, and the inclined ejector seat 2 drives the drag rod 3 to move through the slider, so that the drag rod 3 drives the inclined ejector 1 to move to eject the molded product from the mold.
[0027] Furthermore, the drag rod 3 is fixedly connected to the mold water transfer block 7 by means of threaded engagement. By adopting the above solution, the fixed connection between the drag rod 3 and the mold water transfer block 7 is facilitated.
[0028] Furthermore, the upper fixing block 5 is provided with an upper connection hole 51, the top end of the reinforcing rod 4 extends into the upper connection hole 51 and is rotatably connected to the upper connection hole 51 through a rotating shaft; the lower fixing block 6 is provided with a lower connection hole, the bottom end of the reinforcing rod 4 extends into the lower connection hole and is rotatably connected to the lower connection hole through a rotating shaft. By adopting the above scheme, the reinforcing rod 4 and each fixing block can rotate relative to each other within a certain range.
[0029] Furthermore, fixing block mounting holes are respectively provided on the upper fixing block 5 and the lower fixing block 6. By adopting the above solution, the fixing and mounting of each fixing block is facilitated.
[0030] Furthermore, the inclined top seat 2 comprises two half seat bodies 21 arranged opposite to each other at a distance, the same side ends of the two half seat bodies 21 are fixedly connected by a connecting piece 8, and the opposite inner sides of the two half seat bodies 21 are respectively provided with sliding grooves, and the two sides of the slider are respectively slidably matched with the sliding grooves of the two half seat bodies 21.
