Description

Technical Field

[0001] The present application relates to the field of inclined top cooling, and in particular to a cooling structure of an inclined top of a mold. Background Art

[0002] The main functions of the mold inclined ejector include improving the extrusion performance of the mold, optimizing the filling performance of the mold, realizing lateral core pulling, improving product quality, improving production efficiency, improving product precision, reducing residual stress, reducing production costs and improving market competitiveness. If the inclined ejector does not carry cooling water, it will seriously affect the mold movement and product quality.

[0003] When cooling the inclined ejector pin of the mold, the existing cooling method is to allow cooling water to pass through the inclined ejector pin, that is, a water hole is opened inside the inclined ejector pin, so that cooling water can flow through the water hole to cool the inclined ejector pin. However, the bottom of the existing inclined ejector pin is connected to a water supply hose. During the mold opening process, the inclined ejector plate will be separated from the mold base, thereby exposing the hose at the bottom of the inclined ejector pin. During the mold closing process, part of the hose is likely to enter between the inclined ejector plate and the bottom plate, thereby crushing the hose during the mold closing process. For this reason, we propose a cooling structure for the mold inclined ejector pin. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a cooling structure of a mold inclined top, aiming to improve the problem of hose being crushed in the existing inclined top cooling structure.

[0006] In a specific embodiment, connecting rods are screwed on the side walls at both ends of the upper mold, and plug blocks are fixedly connected to the facing surfaces of the two connecting rods. The two plug blocks are respectively inserted into the side walls at both ends of the inclined top plate.

[0007] In a specific embodiment, the inclined ejector assembly includes an inclined ejector rod that slides through the inclined ejector plate, a water cooling hole is opened in the inclined ejector rod, and a hose is connected to the bottom of the inclined ejector rod.

[0008] In a specific embodiment, a fastening joint is connected to the bottom of the inclined top rod, one end of the hose is connected to the water cooling hole through the fastening joint, and the other end of the hose is connected to a transition joint, which is screwed to the inclined top plate.

[0010] In a specific embodiment, the sheath assembly includes a screw and a sheath, the screw locks the sheath on the bottom of the inclined top plate, and the hose is located in the sheath.

[0012] In a specific implementation manner, limiting sleeves are screwed onto the side walls at both ends of the bottom plate, and the two limiting sleeves are respectively sleeved on the bottoms of the two connecting rods.

[0013] The beneficial effects of the present application are as follows: by setting an inclined top plate, the inclined top plate is connected to the upper mold.

It should be noted that slots are provided on the side walls at both ends of the inclined top plate 40, so that the plug blocks 520 are inserted into the slots, so that the upper mold 50 drives the inclined top plate 40 to move synchronously through the connecting rods 510. Further, a screw is slidably penetrated on the connecting rods 510, and at the same time, the upper mold A screw hole compatible with the screw is opened on the side wall of 50, so that the screw passes through the connecting rod 510 and is connected to the screw hole, so as to fix the connecting rod 510 on the upper mold 50, and the insert block 520 is inserted in the slot. In addition, the side walls at both ends of the bottom plate 10 are screwed with a limiting sleeve 120, and the two limiting sleeves 120 are respectively sleeved on the bottom of the two connecting rods 510.

Furthermore, when the inclined top plate 40 moves, the slider 430 performs adaptive movement between the two limit blocks 420, that is, slides left and right between the two limit blocks 420.

[0027] See also Figure 4 and 5The sheath assembly 70 includes a screw 710 and a sheath 720. The screw 710 locks the sheath 720 on the bottom of the inclined top plate 40. The hose 630 is located in the sheath 720. A receiving groove 110 is provided on the bottom plate 10. The sheath 720 is located in the receiving groove 110. Specifically, by installing the sheath 720 at the bottom of the inclined top plate 40, the hose 630 can be prevented from moving out of the sheath 720 during the movement of the inclined top plate 40, thereby preventing part of the hose 630 from moving between the inclined top plate 40 and the bottom plate 10, thereby avoiding the situation where the hose 630 is crushed. It should be noted that a threaded hole is provided at the bottom of the inclined top plate 40, and the threaded hole is adapted to the screw 710 to realize the disassembly and assembly of the sheath 720.
