Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a multi-purpose core mold. Background Technology
[0002] Concrete pipes are made of reinforced concrete and used to transport fluids. Existing reinforced concrete pipes are generally precast. In the precasting process, pipe core molds are required to make concrete pipes. Since concrete pipes come in various sizes, special molds are required for different sizes. This specialization of molds leads to reduced mold utilization and increased costs. Utility Model Content
[0003] To address the above problems, this utility model provides a multi-purpose core mold that is simple in structure, convenient and practical, and cost-effective.
[0004] The technical solution of this utility model is as follows: a multi-purpose core mold, including a concrete pipe mold body, the concrete pipe mold body including an inner mold and an outer mold arranged inside and outside, and also including a multi-purpose component, the multi-purpose component being connected in the lower middle part between the inner mold and the outer mold; the multi-purpose component is a standard bottom mold, a movable bottom mold, a socket end bottom mold of a relay or a spigot end bottom mold of a relay.
[0005] The standard bottom mold is fitted and snapped into the bottom of the concrete pipe mold body. Standard pipes can be produced through this fitting and snapping.
[0006] The movable bottom mold is adapted and snapped into the main body of the concrete pipe mold. Through the adaptation and snapping of the movable bottom mold and the main body of the concrete pipe mold, a standard short pipe with a length of 3 meters can be produced.
[0007] The bottom mold of the intermediate socket end is adapted and snapped into the main body of the concrete pipe mold. Through the adaptation and snapping of the bottom mold of the intermediate socket end and the main body of the concrete pipe mold, the intermediate socket end pipe (i.e. the pipe concrete of the intermediate socket end part) can be produced.
[0008] The bottom mold of the relay interlock end is adapted and snapped into the main body of the concrete pipe mold. Through the adaptation and snapping of the bottom mold of the relay interlock end and the main body of the concrete pipe mold, the relay interlock end pipe (i.e. the pipe concrete of the relay interlock end part) can be directly produced.
[0009] The bottom of the movable bottom mold is connected to a first heightening steel pipe, and the bottom of the first heightening steel pipe is welded to the first bottom mold. The length of the first heightening steel pipe is 70-79cm.
[0010] The first heightening steel pipe has eight sections, which are evenly distributed in a ring.
[0011] By setting up the first bottom mold and the first heightening steel pipe, the first bottom mold and the first heightening steel pipe can effectively fix and limit the movable bottom mold, thereby facilitating the manufacture of standard short pipe sections.
[0012] The bottom of the socket end bottom mold of the relay is connected to a second heightening steel pipe, and the bottom of the second heightening steel pipe is welded to a second bottom mold. The length of the second heightening steel pipe is 170-177cm.
[0013] The second heightening steel pipe has eight sections, which are evenly distributed in a ring.
[0014] When the concrete pipe mold body is fitted and snapped together with the standard bottom mold, the concrete pipe mold body is only fitted and snapped together with the standard bottom mold, and is not connected to the movable bottom mold, the socket end bottom mold of the intermediate section, or the spigot end bottom mold of the intermediate section.
[0015] When the concrete pipe mold body is fitted and snapped together with the movable bottom mold, the concrete pipe mold body is only fitted and snapped together with the movable bottom mold, and is not connected to the standard bottom mold, the intermediate socket end bottom mold, or the intermediate spigot end bottom mold.
[0016] When the concrete pipe mold body is fitted and snapped into the socket end bottom mold of the relay station, the concrete pipe mold body is only fitted and snapped into the socket end bottom mold of the relay station, and is not connected to the standard bottom mold, the movable bottom mold, or the socket end bottom mold of the relay station.
[0017] When the concrete pipe mold body is fitted and snapped into the bottom mold of the intermediate station spigot end, the concrete pipe mold body is only fitted and snapped into the bottom mold of the intermediate station spigot end, and is not connected to the standard bottom mold, the movable bottom mold, or the bottom mold of the intermediate station socket end. In this way, only the intermediate station spigot end pipe can be produced during production and processing, which is convenient and reliable.
[0018] In operation, this utility model uses the main body of the concrete pipe mold as the base, and combines it with any one of the following: a standard bottom mold, a movable bottom mold, a socket end bottom mold for intermediate stations, and a spigot end bottom mold for intermediate stations. This allows for the effective production of standard pipes, standard short pipes, and intermediate socket end pipes and spigot end pipes, respectively. This greatly improves the utilization rate of the main body of the concrete pipe mold, and the multi-purpose nature of the mold significantly reduces production costs. Attached Figure Description

[0030] The bottom of the movable bottom mold 300 is connected to the first heightening steel pipe 301, and the bottom of the first heightening steel pipe 301 is welded to the first bottom mold 302. The length of the first heightening steel pipe 301 is 70-79cm, which can be set according to actual needs.
[0031] The first height-increasing steel pipe 301 has eight sections, which are evenly distributed in a ring.
