Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a concrete square tube forming mold for partition wall construction. Background Technology

[0002] A concrete square tube forming mold for partition wall construction is a mold used for precast concrete partition wall panels. Its main function is to shape the concrete according to the shape and structure of the mold, thereby producing partition wall panels that meet the design requirements. This mold is usually made of steel or other durable materials, and has high strength, rigidity and stability. It can withstand the lateral pressure during concrete pouring and vibration, and ensure that the concrete maintains the required size and shape after hardening.

[0003] A search revealed Chinese Patent Publication No. CN215511613U, which discloses a concrete square tube forming mold, including a base, an inner mold, and an outer mold. The key feature is that a motor is embedded in the upper end of the base, and a demolding device is connected to the upper end of the base. The demolding device includes a column, the lower end of which is fixedly connected to the upper end of the base. A circular groove is machined on the lower end of the column. A transmission rod is fixedly connected to the outer shaft of the motor, and the end of the transmission rod away from the motor is movably connected to the inner wall of the circular groove via a bearing. Beneficial effects: By setting up a base, inner mold, and outer mold, the flatness of the cross-section and the inner and outer walls of the concrete square tube can be ensured during casting. The demolding device allows the inner mold to be detached from the outer mold after the cast square tube is formed, controlled by the motor, facilitating demolding.

[0004] While the above solution has the advantage of easy demolding, in actual use, it requires manual installation or disassembly of the external mold, which is cumbersome and results in a long demolding time.

[0005] Therefore, there is an urgent need to provide a concrete square tube forming mold for partition wall construction to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the above-mentioned prior art, which requires manual installation or disassembly of the external mold in actual use, which is cumbersome and results in a long demolding time. This utility model provides a concrete square tube forming mold for partition wall construction.

[0007] To solve the above-mentioned technical problems, the present invention provides a concrete square tube forming mold for partition wall construction, including a base and a placement groove set on the top of the base, wherein a mold assembly is provided inside the placement groove.

[0008] The mold assembly includes an inner ring mold and an outer ring mold disposed inside the placement groove, and a transmission unit disposed between the inner ring mold and the outer ring mold;

[0009] The inner ring mold includes an inner template disposed inside the placement groove, an extension portion disposed on the side of the inner template, and a first telescopic portion disposed inside the inner template.

[0010] The outer ring mold includes an outer template disposed inside the placement groove and a second telescopic part disposed outside the outer template. The second telescopic part has the same structure as the first telescopic part.

[0011] The present invention is further configured such that supports are installed at the bottom corners of the base.

[0012] The present invention is further configured such that: there are four inner templates, and the four inner templates form a rectangular structure;

[0013] There are four outer templates, which together form a rectangular structure.

[0014] The present invention is further configured such that each inner template has an extension portion on its opposite side;

[0015] The extended portion includes a storage groove on the side of the inner template, a guide post installed on the side wall of the storage groove, and an extension plate movably disposed on the outside of the guide post. The opposite sides of the guide post, on which the extrusion component is sleeved, are provided with beveled surfaces.

[0016] The present invention is further configured such that: the first telescopic part includes a movable groove disposed on the inner side of the base, a lead screw movably connected inside the movable groove, a sliding sleeve threaded to the outside of the lead screw, a connecting plate installed on the outside of the sliding sleeve, and one end of a push rod installed on the side of the connecting plate, the other end of the push rod being fixedly connected to the inner surface of the inner template.

[0017] The present invention is further configured such that: the transmission unit includes a drive component installed at the center of the bottom of the base, a rotating rod installed at the end of the output shaft of the drive component, a first bevel gear and a second bevel gear installed on the outside of the rotating rod, a third bevel gear meshing with the side of the first bevel gear, and the third bevel gear being installed at the end of the lead screw in the first telescopic part.

[0018] The present invention is further configured such that: a fourth bevel gear is engaged with the side of the second bevel gear, one end of a movable rod is installed on the side of the fourth bevel gear, a fifth bevel gear is installed on the other end of the movable rod, a sixth bevel gear is engaged with the top of the fifth bevel gear, and the sixth bevel gear is installed at the end of the lead screw in the second telescopic part.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, the mold assembly is designed so that when the concrete square tube needs to be demolded after being cast, the drive component first drives the rotating rod to rotate, which in turn drives the first bevel gear to rotate. Since the first bevel gear meshes with the third bevel gear, the screw rod rotates. Under the action of the threaded pair, the sliding sleeve slides along the length of the screw rod. When the sliding sleeve slides, it works with the connecting plate to drive the push rod to move. The movement of the push rod pulls the inner template to move towards the center of the base, thereby separating the inner template from the formed concrete square tube. In addition, the elastic extrusion action of the extrusion component causes the extension plate to retract into the inside of the receiving groove, which facilitates the movement of multiple inner templates.

[0021] As the rotating rod rotates, it drives the second bevel gear to rotate. Since the second bevel gear meshes with the fourth bevel gear, it drives the movable rod to rotate, which in turn drives the fifth bevel gear to rotate. Since the fifth bevel gear meshes with the sixth bevel gear, it drives the lead screw in the second telescopic part to rotate. This, in conjunction with the push rod, pulls the outer template to move outward, causing the outer template to separate from the outer surface of the formed concrete square tube, thus completing the demolding. The operation is relatively convenient, reducing demolding time and improving work efficiency.

[0022] 2. This utility model, through the transmission unit, enables the inner and outer templates to be demolded synchronously via the cooperation of the driving component, rotating rod, movable rod, and multiple bevel gears, thereby reducing production costs. Attached Figure Description

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Please see Figure 1 - Figure 7 A concrete square tube forming mold for partition wall construction includes a base 1 and a placement groove 2 set on the top of the base 1. A mold assembly 3 is set inside the placement groove 2. The mold assembly 3 is used to assemble a concrete square tube forming mold and facilitates demolding of the formed concrete square tube.

[0033] The mold assembly 3 includes an inner ring mold 31 and an outer ring mold 32 disposed inside the placement groove 2, and a transmission unit 33 disposed between the inner ring mold 31 and the outer ring mold 32;

[0034] The inner ring mold 31 includes an inner template 311 disposed inside the placement groove 2, an extension portion 312 disposed on the side of the inner template 311, and a first telescopic portion 313 disposed inside the inner template 311.

[0035] There are four inner templates 311, and the four inner templates 311 form a rectangular structure.

[0036] Each inner template 311 has an extension portion 312 on its opposite side.

[0037] The extension portion 312 includes a storage groove 3121 disposed on the side of the inner template 311, a guide post 3122 installed on the side wall of the storage groove 3121, and an extension plate 3123 movably disposed on the outside of the guide post 3122. A compression member 3124 is sleeved on the outside of the guide post 3122. Preferably, the compression member 3124 is a compression spring.

[0038] The two adjacent extension plates 3123 are provided with beveled surfaces on their opposite sides, so that the two adjacent extension plates 3123 fit tightly together, preventing concrete from entering the inner side of the inner ring mold 31 during pouring.

[0039] The first telescopic part 313 includes a movable groove disposed inside the base 1, a lead screw 3131 movably connected inside the movable groove, a sliding sleeve 3132 threadedly connected to the outside of the lead screw 3131, a connecting plate 3133 installed on the outside of the sliding sleeve 3132, and one end of a push rod 3134 installed on the side of the connecting plate 3133. The other end of the push rod 3134 is fixedly connected to the inner surface of the inner template 311.

[0040] The outer ring mold 32 includes an outer template 321 disposed inside the placement groove 2 and a second telescopic part 322 disposed outside the outer template 321. The second telescopic part 322 has the same structure as the first telescopic part 313.

[0041] There are four outer templates 321, and the four outer templates 321 form a rectangular structure.

[0042] Each base 1 has a support 11 installed at its bottom corner.

[0043] The transmission unit 33 includes a drive member 331 installed at the bottom center of the base 1, a rotating rod 332 installed at the end of the output shaft of the drive member 331, a first bevel gear 333 and a second bevel gear 334 installed on the outside of the rotating rod 332, a third bevel gear 335 meshing with the side of the first bevel gear 333, and the third bevel gear 335 installed at the end of the lead screw 3131 in the first telescopic part 313. Preferably, the drive member 331 is a servo motor.

[0044] The second bevel gear 334 is engaged with the fourth bevel gear 336 on its side. The fourth bevel gear 336 has one end of a movable rod 337 installed on its side. The other end of the movable rod 337 is equipped with a fifth bevel gear 338. The top of the fifth bevel gear 338 is engaged with a sixth bevel gear 339. The sixth bevel gear 339 is installed at the end of the lead screw 3131 in the second telescopic part 322.

[0045] When the concrete square tube needs to be demolded after being cast, the drive component 331 first drives the rotating rod 332 to rotate, which in turn drives the first bevel gear 333 to rotate. Since the first bevel gear 333 meshes with the third bevel gear 335, it drives the lead screw 3131 to rotate. Under the action of the threaded pair, the sliding sleeve 3132 slides along the length of the lead screw 3131. When the sliding sleeve 3132 slides, it drives the push rod 3134 to move through the connecting plate 3133. The movement of the push rod 3134 pulls the inner template 311 to move towards the center of the base 1, thereby separating the inner template 311 from the formed concrete square tube. In addition, the elastic extrusion action of the extrusion component 3124 causes the extension plate 3123 to retract into the inside of the receiving groove 3121, which facilitates the movement of multiple inner templates 311.

[0046] As the rotating rod 332 rotates, it drives the second bevel gear 334 to rotate. Since the second bevel gear 334 meshes with the fourth bevel gear 336, it drives the movable rod 337 to rotate, which in turn drives the fifth bevel gear 338 to rotate. Since the fifth bevel gear 338 meshes with the sixth bevel gear 339, it drives the lead screw 3131 in the second telescopic part 322 to rotate. This, in turn, pulls the outer template 321 outward through the push rod 3134, causing the outer template 321 to separate from the outer surface of the formed concrete square tube, thus completing the demolding.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
