Description

Technical Field

[0001] This utility model relates to a drainage well cover mold, specifically a drainage well cover mold that is easy to cast and demold, belonging to the field of water conservancy engineering mold technology. Background Technology

[0002] Drainage well cover molds are specialized forming tools used for the mass production of well covers made of concrete or cast iron. They are widely used in water conservancy projects. Their core function is to ensure the dimensional accuracy, structural strength, and surface quality of well covers through standardized design and precise manufacturing, while improving production efficiency and reducing costs.

[0003] A prefabrication mold for manhole covers, disclosed in Chinese Patent Application Publication CN213440265U, includes a supporting base plate. A surrounding plate is provided around the supporting surface of the supporting base plate, and a handle protrusion is provided on the supporting surface. Using this technical solution, the manhole cover prepared by the prefabrication mold can be fitted with a handle, facilitating installation. Furthermore, using a standardized prefabrication mold ensures consistent and stable specifications for the prefabricated manhole covers. However, this technical solution is not convenient for casting and demolding the drainage manhole cover within the mold. Since the mold is mostly a rigid integral structure, the manhole cover, after curing, fits tightly against the inner wall of the mold cavity, requiring manual hammering and prying for demolding. A single demolding takes ≥10 minutes and easily causes chipping at the corners and scratches on the surface of the manhole cover, resulting in a finished product qualification rate of only 70%-80%.

[0004] Therefore, a drainage well cover mold that is easy to cast and demold is proposed here. Utility Model Content

[0019] Please refer to this carefully. Figure 1 and Figure 4 The casting auxiliary component 4 includes several sets of casting rods 402, a total of 16 casting rods 402, to facilitate the casting of 16 drainage holes on the surface of the drainage well cover. The outer surface of each set of casting rods 402 is fixedly connected to the inner wall of the mold top cover 201. Two sets of auxiliary rods 401 are fixedly connected to the inner wall of the mold top cover 201. The two sets of auxiliary rods 401 are used to facilitate the casting of two sets of holes on the surface of the drainage well cover, so that the reinforcing bars can pass through the auxiliary rods 401 for fixing to the drainage well. The bottom end of each set of auxiliary rods 401 and the bottom end of each set of casting rods 402 are in contact with the upper surface of the sliding base plate 203. By using the two sets of casting rods 402 and the two sets of auxiliary rods 401, the casting of the drainage well cover can form a round hole, so as to facilitate the formation of drainage holes in the drainage well cover, thereby facilitating the installation and use of the drainage well cover.

[0020] In use, the following steps are taken: First, connect the vibration motor 306 to the mobile power supply 6. When using this easy-to-cast and demold drainage well cover mold to cast drainage well covers, first, manually place the drainage well cover mold on a horizontal surface so that the bottom surfaces of the two sets of support bases 305 are in contact with the upper surface of the horizontal surface. The two sets of support legs 301, support sleeves 304, and support bases 305 form the support structure of the drainage well cover mold, allowing it to be easily supported in the required position. Then, manually slide the sliding base plate 203 into the mold body 1 to fix the bottom surface of the sliding base plate 203 in place. Block 204 is inserted into the positioning groove 202 to facilitate the stable installation of the sliding base plate 203 into the mold body 1. At the same time, the mold top cover 201, along with the auxiliary rods 401 and the pouring rods 402, is manually placed on top of the mold body 1. This allows the bottom ends of the multiple auxiliary rods 401 and the multiple pouring rods 402 to contact the upper surface of the sliding base plate 203. This allows the multiple guide cylinders 206 fixed to the inner wall of the mold top cover 201 to be inserted into the sliding base plate 203 and to contact the upper surfaces of the multiple positioning blocks 204. The mounting bolts 403 are manually threaded through the mold top cover 201 and into the mounting threaded holes 404, thereby enabling the drainage well cover mold to be assembled together. Next, the cement to be poured into the drainage well cover is manually mixed into concrete according to the specified ratio and transported from the top cover 201 of the mold to the sliding base plate 203 inside the mold body 1. This allows the drainage well cover to be poured into the drainage well cover mold. Multiple vibration motors 306 fixed to the bottom of the mold body 1 are used to vibrate and compact the drainage well cover material inside the mold body 1. Simultaneously, four circles are provided on the top cover 201. During the production of the drainage well cover, a vibrating rod is inserted through these circles into the mold body 1 to vibrate the drainage well cover material and remove air bubbles. After the drainage well cover inside the mold cools naturally, the vibration motors 306 fixed to the bottom of the mold body 1 are controlled to cause the support legs 301 fixed to the bottom of the mold body 1 to slide within the support sleeve 304. The compression spring 302 then causes the mold body 1 to vibrate, facilitating the compaction of the mold body. The drainage well cover inside body 1 is demolded. After vibration, the installation bolts 403 are manually twisted to prevent the mold top cover 201 from being connected to the mold body 1. Holding the demolding hook 208 allows the lifting screw 207 to pass through the guide cylinder 206 and extend into the positioning block 204. Rotating the lifting screw 207 allows it to be threaded into the lifting threaded hole 205, thereby connecting the lifting screw 207 and the demolding hook 208 to the sliding base plate 203 inside the mold body 1, thus enabling easy demolding. The mold body 1 and the sliding base plate 203, along with the drainage well cover, can be pulled out of the mold body 1 by manually holding the demolding hook 208. The mold body 1 set on the sliding base plate 203 can be pulled by manually twisting the lifting screw 207 in the lifting threaded hole 205, which facilitates the pulling out of the guide cylinder 206, auxiliary rod 401 and pouring rod 402 inside the drainage well cover, and the drainage well cover can be removed from the sliding base plate 203, thus facilitating the demolding of the drainage well cover inside the mold.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
