Embodiment 1

[0024] refer to figure 1 , a compression molding machine for electric manhole cover production, including a workbench 1, a mold body 2 is fixedly connected to the workbench 1, a hydraulic cylinder 3 is installed on the workbench 1 through a frame body, and a fixed rod is fixedly connected to the output end of the hydraulic cylinder 3 4. The bottom end of the fixed rod 4 is fixedly connected with the pressure module 5, and the pressure module 5 is sealed and slidably matched with the mold body 2 in the vertical direction, wherein the inner peripheral side and bottom surface of the mold body 2 and the lower surface of the pressure module 5 form a first type Cavity, the hydraulic cylinder 3 works, and its output pushes the pressure module 5 to move downward and press fit in the mold body 2 to form the first cavity. The first cavity forms the shape of the manhole cover with a larger diameter. Pressurized holding and forming out of the mold, thus casting a manhole cover with a larg...

Embodiment 2

[0039] refer to Figure 4 , on the basis of Embodiment 1, the sliding block 71 is set as a rectangular block, and the sliding block 71, the outer ring block 52 and the inner module 51 are vertically opened with a limit hole 711, and the inner pin of the limit hole 711 is connected with the limit pin 712, the limit pin 712 extends out of the bottom of the inner module 51 and the length is equal to the height of the mold body 2, wherein the limit pin 712 constitutes the well cover installation hole, and the outer ring block 52 and the inner module 51 form a further limit effect through the limit pin 712, and Form a limiting effect on the extruding mechanism 6, improve the stability of the extruding mechanism, and at the same time form the manhole cover installation hole after the manhole cover casting is completed, wherein the four limiting holes 711 and the threaded holes 5211 are staggered with each other.

[0040] After the first cavity is formed, the stopper pin 712 is inser...

Abstract

The invention discloses a molding press for electric well lid production and well lid production equipment. The molding press comprises a workbench, the workbench is fixedly connected with a mold body, the workbench is provided with a hydraulic cylinder through a frame body, an output end of the hydraulic cylinder is fixedly connected with a fixed rod, the bottom end of the fixed rod is fixedly connected with a mold pressing block, the mold pressing block is in sealing sliding fit with the mold body in the vertical direction, the mold pressing block comprises an inner mold block and an outer ring block, the outer ring block is composed of two semi-ring blocks, and the outer ring block is connected to the peripheral side of the inner mold block in a clamped mode. According to the molding press for the electric well lid production provided by the invention, the separate mold pressing block composed of the inner mold block and the outer ring block is adopted, the lower surface of the mold pressing block and the inner surface of the mold body form a first cavity; and the outer ring block is dismounted, turned over and then mounted in the mold body, and the lower surface of the inner mold block, the inner bottom surface of the mold body and the inner circumferential side of the outer ring block form a second cavity, so that two types of well lids with different diameters can be cast.

Description

technical field [0001] The invention relates to the technical field of manhole cover production equipment, in particular to a compression molding machine for electric manhole cover production. Background technique [0002] The existing electric well cover is used to cover the deep well set when laying the power system, thereby preventing people, small animals or other sundries from falling into the deep well. Most of the existing manhole covers are formed by cast iron casting. The casting of the cast iron manhole covers is completed after the molten iron is cooled and formed by filling molten iron into the cavity formed by the mold. When casting the manhole cover, the pressing module is pressed into the mold body through the driving mechanism, and the cavity for casting is formed between the two, and the molten iron can be filled. The Chinese authorized utility patent with the application number CN201920091426.0 discloses a molding machine for manhole cover production, whic...
