Description

Technical Field

[0001] The utility model belongs to the technical field of precast column molds, and particularly relates to a demoulding structure for a precast column mold. Background Technique

[0002] With the development of building technology and the wide application of prefabricated buildings, prefabricated components such as precast wall panels and precast columns are required in prefabricated buildings. Molds are needed in the production process of prefabricated components. By injecting manufacturing materials such as concrete into the molds, they are solidified and formed. After the prefabricated components are formed, demoulding operations are carried out on them; precast columns are divided into hollow precast columns and solid precast columns.

[0003] In the Chinese patent with the publication number CN214353160U, a precast column mold that is convenient for demoulding is mentioned. When pouring concrete into the assembled mold, the concrete will flow into the gap between the card slot and the card block. Since a sealing gasket is fixed inside the card slot, the gap at the connection between the card slot and the card block is blocked, thereby preventing the leakage of concrete inside the mold.

[0004] Although the precast column mold in the above-mentioned prior art can be demoulded, during actual demoulding, half of the volume of the precast column is still inside the bottom mold, which makes it still difficult to take out the precast column from the bottom mold. In addition, this precast column mold can only be used for the production and demoulding of solid precast columns and cannot meet the various production requirements of precast columns. For this reason, we propose a demoulding structure for a precast column mold. Summary of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1-5 As shown, the present utility model provides a demolding structure for a precast column mold, including a base 1, a lower mold base 5 fixedly connected to the middle of the top of the base 1, two symmetrically distributed mold covers 4 arranged outside the lower mold base 5, and a demolding mechanism 2 arranged on the top of the base 1;

[0026] The demolding mechanism 2 includes a driving motor 203 fixedly connected to the top of the base 1. The driving motor 203 is fixedly connected with a bidirectional lead screw 201 through an output shaft. A fixing block 206 is threadedly connected to the outside of the bidirectional lead screw 201. An insertion plate 204 is fixedly connected to the outside of the lower mold base 5. A through slot 207 is opened on the outside of the mold cover 4, and an adjusting component 3 is arranged on the outside of the base 1.

[0027] In a further embodiment, referring to Figures 1-4, There are two sets of fixed blocks 206. The two sets of fixed blocks 206 are fixedly connected to the outside of the corresponding mold cover 4. The fixed blocks 206 can drive the mold cover 4 to move. When the bidirectional threaded rod 304 rotates, it can drive the mold cover 4 to move in opposite directions, so as to demold the precast column or combine the molds. The left and right sides of the outside of the bidirectional lead screw 201 are provided with reverse threads. The setting of the reverse threads can drive the two fixed blocks 206 to move in opposite directions when it rotates. One end of the bidirectional lead screw 201 far from the driving motor 203 is movably connected with a support block 202 through a bearing. The support block 202 supports the bidirectional lead screw 201 from the other end to ensure the stability of the bidirectional lead screw 201 during use. The support block 202 is fixedly connected to the top of the base 1.

[0028] In this embodiment, the bidirectional lead screw 201 rotates under the action of the driving motor 203, thereby driving the fixed blocks 206 on both sides to move. Through the fixed blocks 206, the two mold covers 4 are moved in opposite directions to open, and the demolding of the precast column is completed.

[0029] In a further embodiment, refer to Figure 1 and Figure 4 , Two symmetrically distributed arc-shaped grooves 205 are opened at the top of the mold cover 4. When the two mold covers 4 are combined, the two arc-shaped grooves 205 can form two holes. Concrete can be injected into the two holes respectively or the gas in the mold can be discharged. The two sides of the two inserting plates 204 away from each other respectively penetrate through the corresponding inserting slots 207 and are slidably connected to the inner side of the inserting slots 207. The inserting plates 204 can block the inserting slots 207 to ensure the stability inside the mold and ensure the sealing effect of the mold.

[0030] In this embodiment, the two arc-shaped grooves 205 can form a round hole for pouring concrete and discharging the air inside the mold, ensuring the quality of the precast column and reducing the generation of bubbles.

[0031] In a further embodiment, refer to Figure 1 and Figure 4, the adjusting assembly 3 includes a fixing plate 301 which is fixedly connected to the outside of the base 1. Above the lower die base 5, there is a core rod 302 which can be placed inside the mold and can be used to prepare a hollow precast column. If the core rod 302 is removed, a solid precast column can be prepared. Both the front and rear ends of the core rod 302 are provided with limiting grooves 305, and limiting blocks 303 are arranged at both the front and rear ends of the core rod 302. The limiting grooves 305 and the limiting blocks 303 can limit the core rod 302 to ensure the stability of the placement of the core rod 302. On the far - away sides of the two limiting blocks 303, threaded rods 304 are movably connected through bearings. The rotation of the threaded rods 304 can drive the movement of the limiting blocks 303, so that the limiting blocks 303 enter or move out of the limiting grooves 305. Notches 307 are opened on both the front and rear sides of the two mold covers 4. After the two mold covers 4 are combined, the notches 307 are located outside the limiting blocks 303, facilitating the movement of the limiting blocks 303. The far - away ends of the two threaded rods 304 respectively penetrate through the corresponding fixing plates 301 and are threadedly connected to the corresponding fixing plates 301. A limiting rod 306 is fixedly connected to the outside of the fixing plate 301, and a limiting hole is opened on the outside of the limiting block 303. The limiting rod 306 is slidably connected to the inside of the limiting hole. Under the action of the limiting hole and the limiting rod 306, the movement track of the limiting block 303 can be limited to ensure that it can only move in the front - and - back direction.

[0032] In this embodiment, the preparation of hollow precast columns or solid precast columns can be selected according to the preparation requirements of the precast columns, and rapid demoulding can be carried out after preparation to ensure the production efficiency of the precast columns.

[0033] The working principle of the present utility model is as follows:

[0034] According to the preparation requirements of the precast column, select whether to install the core rod 302. If it is not necessary to install, rotate the threaded rod 304 to adjust the position of the limiting block 303 so that its outer side is on the same plane as the inner side of the mold cover 4;

[0035] Inject concrete through one of the holes opened at the top of the mold cover 4. As the concrete is injected, the air in the mold is discharged outwards until the concrete is filled and then stop, and wait for the concrete to solidify;

[0036] After it is completely solidified, start the driving motor 203. The driving motor 203 drives the bidirectional lead screw 201 to rotate through the output shaft. The rotation of the bidirectional lead screw 201 drives the two fixing blocks 206 to move. The movement of the fixing blocks 206 drives the mold cover 4 to move until the precast column is completely demoulded;

[0037] At this time, the completed precast column is taken out by a hoisting device or manually to complete the preparation of the precast column.

[0038] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
