Description

Technical Field

[0001] The utility model specifically relates to a forming mold for precast manhole covers, belonging to the technical field of molds. Background Art

[0002] Precast manhole covers are an indispensable part of urban infrastructure construction. Their quality and performance are directly related to the travel safety of citizens and the urban image. Precast manhole covers are usually made of materials such as reinforced concrete, steel fiber concrete or metal materials to ensure their sufficient load-bearing capacity and durability. In some high-end products, a unique concrete formula may also be used, supplemented with materials such as a relatively dense steel bar skeleton, glass fiber, ore, sand and gravel, and modifiers to improve the strength, hardness and service life of the manhole cover. When making precast manhole covers, a forming mold is needed to shape the manhole cover.

[0003] A forming mold for precast manhole covers, which relates to the technical field of molds, includes an upper mold and a lower mold. A pouring port is opened on the top surface of the upper mold, and a positioning groove is opened on the top surface of the lower mold. A compression spring is fixedly connected to the bottom surface of the inner wall of the positioning groove. A positioning rod is fixedly connected to the bottom surface of the upper mold. The positioning rod is movably inserted into the inner wall of the positioning groove. The lower end of the positioning rod is in contact with the upper end of the compression spring. A slot is movably inserted into the side surface of the positioning rod. In this application, by pulling the insertion plate to separate it from the slot and causing the positioning rod to lose its limit, at this time, the compression spring pushes the positioning rod and the upper mold to move upward and separate from the lower mold, and then the lower mold is tapped to separate the manhole cover from the inner wall of the lower mold. Then, the cylinder is used to push the demolding plate upward to push the manhole cover out of the lower mold, so as to facilitate the operator to take the manhole cover. Therefore, the device is simple and convenient to demold.

[0004] However, in the above technical solution, the molding material is directly injected into the mold, and the molding material is likely to be unevenly distributed, resulting in uneven density everywhere in the precast manhole cover, thus affecting the quality of the manhole cover. At the same time, the upper mold and the lower mold are clamped and fixed by a clamping method, and gaps are likely to appear between the molds, causing the outflow of the molding material. In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a forming mold for precast manhole covers to solve the above problems. It has the advantages of uniform molding density and good sealing effect. The upper mold and the lower mold are connected by a multi-section hydraulic self-locking push rod and sealed by an isolation ring, improving the sealing effect between the upper mold and the lower mold during the precasting process and avoiding the outflow of the molding material. At the same time, the shaking assembly can drive the lower mold and the upper mold to shake during precasting, improving the uniformity of the molding material and the quality of the precast manhole cover.

[0006] The present utility model achieves the above object through the following technical solutions. A precast manhole cover forming mold includes an installation frame.

And a feeding pipe is installed at the upper end of the upper mold. When in use, first, the multi-stage hydraulic self-locking push rod drives the upper mold to be clamped on the lower mold. Then, forming materials are conveyed between the lower mold and the upper mold through the feeding pipe. Then, the shaking component drives the lower mold and the upper mold to shake, so as to evenly distribute the density of the forming materials everywhere and improve the quality of the precast manhole cover.

[0007] Further, in order to improve the sealing effect, an isolation ring is fixedly installed at the lower end of the upper mold. The outer wall of the isolation ring is in close contact with the inner wall of the lower mold. A cushion ring is fixedly installed at the lower end of the isolation ring. A clamping groove is opened at the lower end inside the lower mold. The cushion ring can be clamped in the clamping groove.

[0008] Further, in order to prevent the upper mold and the lower mold from being misaligned, limiting columns are circumferentially and arrayedly installed on the outer circumference of the lower end of the upper mold. Limiting holes are circumferentially arrayedly opened at the upper end of the lower mold. The limiting columns correspond to the limiting holes.

[0009] Further, in order to enable the lower mold to be slidably installed at the lower end inside the installation frame, a T-shaped clamping strip is fixedly installed at the lower end of the lower mold. The T-shaped clamping strip is slidably clamped in the T-shaped sliding groove.

[0010] Further, in order to drive the rotating disk to rotate, the shaking component includes a control motor. The control motor is fixedly installed on one side of the lower end inside the installation frame. And the output end of the control motor is fixedly installed with a rotating disk.

[0011] Further, in order to drive the lower mold to shake, a connecting ring is slidably clamped on one side of the rotating disk. One side of the connecting ring is fixedly installed with a connecting rod. The other end of the connecting rod is fixedly connected to the outer side of the lower mold.

[0012] Further, in order to increase the cooling rate of the forming materials, a cooling groove is opened inside the lower mold. Water inlet pipes and drain pipes are installed on both sides of the lower mold. One ends of the water inlet pipes and the drain pipes are both communicated with the cooling groove.

[0013] Furthermore, in order to facilitate the removal of the prefabricated manhole cover after production, a pop-up groove is provided in the middle of the lower end inside the lower mold. A plurality of micro-push rods are installed in a circumferential array at the lower end inside the pop-up groove, and a push plate is fixedly installed at the upper end of the micro-push rod.

[0014] The technical effects and advantages of the present utility model are as follows: The upper mold and the lower mold are connected by a multi-stage hydraulic self-locking push rod and sealed by an isolation ring, which improves the sealing effect between the upper mold and the lower mold during the prefabrication process, avoids the situation of the molding material flowing out. At the same time, the shaking assembly can drive the lower mold and the upper mold to shake during prefabrication, improving the uniformity of the molding material and the quality of the prefabricated manhole cover.
