Detailed ways

The preferred technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings.

Example 1

A mold for the compression molding of stainless steel manhole covers, shown in Figures 1 and 2, includes a bottom plate 1, a guide rod 2, a connecting block 3, a lower pressing mold 4, a placing plate 5 and a clamping mechanism 6, the bottom plate 1 The left and right sides of the top are fixedly connected with guide rods 2, and a connecting block 3 is slidably connected between the two guide rods 2. The bottom middle of the connecting block 3 is welded with a lower pressure mold 4 that can compress the well cover, and the middle of the top of the bottom plate 1 is welded. A placing plate 5 capable of placing the manhole cover is fixedly connected, and a clamping mechanism 6 capable of clamping and fixing the manhole cover is provided on the bottom plate 1 .

As shown in FIGS. 1 and 3 , the clamping mechanism 6 includes a limit frame 60 , a connecting plate 61 , a first spring 62 , a pressing plate 63 , a fixing rod 64 , a second spring 65 and a moving block 66 . The limit frames 60 are fixedly connected to the sides, the two limit frames 60 are located between the two guide rods 2, and the two limit frames 60 are slidably connected with connecting plates 61, and the two connecting plates 61 are connected to each other. Two first springs 62 are connected between the limit frames 60 that are close to each other, and two pressure plates 63 capable of clamping and fixing the manhole cover are slidably connected to the two limit frames 60 . The connecting plates 61 with a closer distance are connected, the tops of the two connecting plates 61 are fixed with fixed rods 64, the left and right sides of the connecting block 3 are fixed with moving blocks 66, and the two moving blocks 66 are fixed with the closer distance. The rods 64 are slidably connected, and a second spring 65 is connected between the two moving blocks 66 and the connecting plate 61 with a closer distance.

As shown in FIG. 5 , it also includes a top plate 81 and a third spring 82 , a top plate 81 is slidably connected to the top of the placing plate 5 , and a third spring 82 is connected between the top plate 81 and the placing plate 5 .

The manhole cover is compression molded in the factory. When the mold needs to be used, first install the mold on the press, and make the connecting block 3 move downward after the press is started. After the mold is installed in the press, the manhole cover can be placed on the press. On the plate 5, after placing it, start the pressing machine, so that the connecting block 3 moves downward, and the downward movement of the connecting block 3 will slide down along the guide rod 2. When the connecting block 3 slides down, the pressing die 4 also At the same time, the moving block 66 will slide down along the fixed rod 64, and the second spring 65 will be compressed. After the second spring 65 is compressed to the limit, the moving block 66 will drive the fixed rod 64 to move downward, and the fixed The downward movement of the rod 64 will drive the connecting plate 61 to slide down along the limit frame 60, and the downward sliding of the connecting plate 61 will drive the pressing plate 63 to move downward, and at the same time the first spring 62 will be compressed. The manhole cover will be clamped and fixed. At this time, the pressing mold 4 will also press-mold the manhole cover. In this way, during the process of manhole cover compression molding, the manhole cover is clamped and fixed, which can prevent the manhole cover from moving freely during the process of compression molding. Affects the compression molding effect, and when the lower pressing mold 4 performs compression molding on the manhole cover, the top plate 81 will be squeezed by the manhole cover and slide down along the placing plate 5, and the third spring 82 will be compressed. After the compression molding of the manhole cover is completed, the pressing can be started. When the connecting block 3 slides up, the moving block 66 will slide up along the fixed rod 64, and the second spring 65 will be reset. After the second spring 65 is reset, The connecting plate 61 will move upward along the limit frame 60 under the reset action of the first spring 62, and the fixing rod 64 will also move upward. When the connecting plate 61 moves upward, the pressing plate 63 will also move upward, so that the pressing plate 63 will also move upward. The manhole cover will no longer be clamped and fixed, and the top plate 81 will slide upward under the reset action of the third spring 82. When the top plate 81 moves upward, the compression-molded top cover will be pushed out, so that the manhole cover can be easily installed. Take it out, then close the pressing machine, and then transfer the pressed well cover to the next process for processing.

On the basis of Embodiment 1, as shown in FIG. 4 , a feeding mechanism 7 is also included. The feeding mechanism 7 includes a bracket 71 and a pulley 72 , and brackets are fixedly connected to the left and right sides of the front side of the top of the bottom plate 1 71. Two pulleys 72 are rotatably connected to the two brackets 71.

As shown in FIG. 5 , a rotating block 10 is also included, and the rear side of the placing plate 5 is rotatably connected with the rotating block 10 .

As shown in FIG. 1 and FIG. 5 , a knurled anti-skid block 11 is also included, and a knurled anti-skid block 11 is fastened to the front side of the top of the placing plate 5 .

When the manhole cover is to be pressed, the manhole cover must be placed first. In the specific operation, the manhole cover is placed on the pulley 72, and then the manhole cover is moved backward. When the manhole cover moves backwards, the pulley 72 will rotate, so that more It is convenient to place the manhole cover on the placing plate 5, and then the above-mentioned action of starting the pressing machine can be repeated to make the manhole cover compressed. Stability, can prevent the manhole cover from shifting at will. After the manhole cover compression molding is completed, the compressed manhole cover can be pushed back. When the manhole cover is pushed back, the rotating block 10 will rotate to assist the user to remove the manhole cover. more convenient.
