Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 9, the utility model provides a mold waterproof sheet, which comprises a waterproof sheet body 1 formed by integral injection molding, wherein the waterproof sheet body 1 is integrally in a strip-shaped flat sheet shape, a water blocking part 2 matched with the size of a mold cooling water hole is formed at the end of the bottom end in a cylindrical shape, the surface of the waterproof sheet body 1 is provided with an O-shaped ring mounting groove 3, an O-shaped ring 4 is mounted in the O-shaped ring mounting groove 3, a notch 5 which is downwards recessed and used for cooling water to flow through is formed in the top surface of the waterproof sheet body 1, and the waterproof sheet body 1 is made of nylon hydrolysis-resistant plastic.
On the basis of the above scheme, the two ends of the water-proof sheet body 1 in the transverse width direction are provided with the reinforcing ribs 6, the lower ends of the reinforcing ribs 6 are in gentle transition with the water-blocking portion 2, the reinforcing ribs 6 are gradually reduced in size from bottom to top in the longitudinal width direction, the top ends of the reinforcing ribs 6 extend to the upper end or the top surface of the water-proof sheet body 1, fig. 1 and 2 are the situation that the reinforcing ribs 6 extend to the upper end of the water-proof sheet body 1, and fig. 3 and 4 are the situation that the reinforcing ribs 6 extend to the top surface of the water-proof sheet body 1.
In addition, as shown in fig. 10, the notch 5 is located in the middle of the top surface of the water-proof sheet body 1, and the notch is semicircular, V-shaped or arc-shaped. Alternatively, the notch 5 is located at a chamfer on one side of the top surface of the water-proof sheet body 1 in the transverse width direction, or at left and right sides.
Further, the bottom surface of the waterproof sheet body 1 extends downward to form a holding part 7.
The waterproof sheet body 1 is formed by integrally injection molding nylon and hydrolysis-resistant plastic, and can be directly plugged into and installed in a cold water hole at the bottom of a die at normal temperature, and a small gap is reserved between the waterproof sheet body 1 and the cooling water hole of the die at the moment, so that the waterproof sheet body and the cooling water hole are in clearance fit. The lower part of the bottom of the water-proof sheet body 1 is limited by the threaded connection of the plug, so that the water-proof sheet body 1 is prevented from falling off in the using process. The temperature of the mold is usually maintained at 100 ℃ in the normal injection molding production process, the mold can float up and down according to the specific mold temperature of different plastic products, and the nylon hydrolysis-resistant plastic can bear the temperature of 180 ℃ at the highest so as to keep the original characteristics. At this time, the mold and the water-proof sheet body 1 will expand after being heated, however, the expansion of the mold is small, the diameter change of the cooling water hole is negligible, but the expansion coefficient of the water-proof sheet body 1 is large, the water-proof sheet body and the water-proof sheet body can be closely attached to the cooling water hole of the mold in the transverse width direction, and the mold and the water-proof sheet body are in interference fit to generate sealing in the transverse width direction, at this time, as shown in fig. 9. The plugging head 2 under the same principle can expand outwards, the cooling water hole of the die is completely plugged in the radial direction, water cannot flow through the lower side and the lateral side, at the moment, as shown in fig. 7, when water flows in the longitudinal width direction of the water-proof sheet body 1, the water flow can only flow upwards, passes through the notch 5 at the top of the water-proof sheet body 1 and passes through the water-proof sheet body 1 to reach the other side of the water-proof sheet body 1, and a good water-carrying effect is achieved to cool the die.
The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the utility model in any way, but any simple modification, equivalent variation or modification made to the above embodiments according to the technical principles of the present utility model still falls within the scope of the technical solutions of the present utility model.
