Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and particularly relates to an openable and closable concrete test block mold. Background Art

[0002] With the continuous development of my country's construction industry, the traditional construction industry has increasingly stringent requirements on project quality. Concrete test blocks are the main means to reflect the quality of concrete products and the strength of on-site structural entities, so how to make good concrete test blocks becomes increasingly important.

[0003] In construction projects, it is often encountered that if the concrete test blocks are not brushed with release agent, the concrete test blocks cannot be removed, and even if they are removed, the concrete test blocks are damaged due to excessive force. The use of release agent will affect the color difference of the concrete test blocks, and the overflowed release agent will also pollute the soil, which is neither economical nor environmentally friendly. In order to solve such problems, a concrete test block mold that can be opened and closed is specially developed, which can reduce or even achieve the effect of eliminating the release agent while ensuring the quality of the concrete test blocks. Utility Model Content

[0004] The purpose of the utility model is to provide an openable concrete test block mold. By setting an opening and closing component, the side panels on both sides of the device can be opened to solve the problem that the existing concrete test blocks cannot be removed without applying a release agent, and even if they are removed, the concrete test blocks are damaged due to excessive force. The use of a release agent will affect the color difference of the concrete test block, and the overflowed release agent will also pollute the soil, which is neither economical nor environmentally friendly.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an openable and closable concrete test block mold, comprising a base plate, wing plates are fixedly connected to the left and right sides of the base plate, a partition is fixedly connected to the top of the base plate, the number of the partitions is two, an opening and closing component is arranged on the top of the base plate, a lifting component is arranged on the bottom of the base plate, the number of the opening and closing components is two, the two opening and closing components are symmetrically arranged around the center of the base plate, the parts contained in the two opening and closing components are the same, the opening and closing components include side panels, and the opening and closing components are arranged to make the concrete test block easier to take out, thereby reducing or even achieving the effect of eliminating the need for a release agent, reducing other demolding tools such as air compressors, and making demolding of concrete test blocks simpler, faster and more economical.

[0007] Furthermore, a handle is fixedly connected to the front of the side panel, and a hinge is fixedly connected to the bottom of the side panel. There are two hinges, and the tops of the two hinges are fixedly connected to the bottom of the base plate. By setting the hinges, the side panels can be opened and merged more conveniently.

[0008] Furthermore, the back side panel is in contact with the front sides of the two wing panels, and pin holes are provided inside the wing panels and the side panels. There are several pin holes, and pins are inserted into the inner walls of the pin holes. A groove one is provided inside the pin, and a pin sheet is inserted into the inner wall of the groove one. By setting the pins, the staff can open the side panel more quickly.

[0009] Furthermore, the lifting assembly includes fixed blocks, and the number of the fixed blocks is four. The tops of the four fixed blocks are fixedly connected to the bottom of the base plate, and two circular grooves are opened inside the four fixed blocks. The inner wall of the two circular grooves is rotatably connected to a rotating rod, and the outer surface of the rotating rod is fixedly connected to a rotating rod. By setting the lifting assembly, the concrete test block is not too tightly connected to the base plate during demolding without the need to use tools to detach it, thereby avoiding damage to the concrete test block during demolding and improving the demolding efficiency of the concrete test block.

[0010] Furthermore, there are three rotating rods, and a square groove one is opened inside the bottom plate. There are three square grooves one, and the parts contained in the three square grooves one are the same. A push block is slidably connected to the inner wall of the square groove one, and a slide groove is opened at the bottom of the push block. A moving block is slidably connected to the inner wall of the slide groove, and the inner wall of the moving block is rotatably connected to the back side of the rotating rod. By setting the moving block, the push block can quickly lift the concrete test block.

[0011] Furthermore, fixed rods are fixedly connected to the left and right sides of the rotating rod, and the two fixed rods are symmetrically arranged with the center of the base plate. The parts contained in the two fixed rods are the same, and two springs are fixedly connected to the back of the fixed rod. By setting the springs, the fixed rod can be driven to return to its original position after the staff releases the push rod.

[0012] Furthermore, a fixing plate is fixedly connected to the back of the two springs, the right side of the fixing plate is fixedly connected to the left side of the wing plate, the left side of the wing plate is fixedly connected to a round rod, the outer surface of the round rod is rotatably connected to a rotating block, and the outer surface of the rotating block is fixedly connected to a push rod. By providing the round rod, the rotating block can be rotated more conveniently and quickly.

[0013] The utility model has the following beneficial effects:

[0014] The utility model provides an opening and closing component. Specifically, when the concrete is completely solidified and reaches the disassembly condition, a small hammer is used to separate the pin pieces from the inside of the pins. The small hammer is used to knock out the pin pieces inside the pins, so that the two side panels can be opened to both sides, reducing half of the adhesion and friction between the concrete test block and the side of the mold, making the concrete test block easier to take out, thereby reducing or even eliminating the need for a release agent, reducing the use of other demolding tools such as air compressors, and making demolding of concrete test blocks simpler, faster and more economical.

[0015] The utility model sets a lifting component, specifically, rotates two push rods toward the back so that the fixed rod can drive the rotating rod to rotate. The rotating rod drives three rotating rods to rotate during the rotation, so that the push block can be pushed to move upward, so that the bottom of the concrete test block can be separated from the top of the base plate. When the concrete test block is too tightly connected to the base plate during demolding, there is no need to use tools to detach it, which avoids damage to the concrete test block during demolding and improves the demolding efficiency of the concrete test block.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the concrete test block is too tightly connected to the bottom plate 1 during demolding, it is not necessary to use a tool to separate it, thereby avoiding damage to the concrete test block during demolding and improving the demolding efficiency of the concrete test block. During the rotation process of the fixed rod 225, the two springs 227 will be driven to deform. When the concrete test block is separated, the push rod 223 is released, and the deformed spring 227 will return the fixed rod 225 to its original position through elastic force, and the pushing block 231 can return to the inside of the square groove 1.
