In the structure, the first driving mechanism 32 drives the side mold brush 31 to rotate so as to clean residues on the side wall of the mold cavity, the side mold brush 31 is matched with the side wall of the mold cavity, namely, a revolving outer contour generatrix of the side mold brush 31 is the same as or approximately the same as the contour line of the side wall of the mold cavity, and a central axis of the side mold brush 31 is vertical to the bottom plane of the mold cavity. In this embodiment, for the convenience of demoulding the square pile, the included angle between the side template and the bottom template of the square pile mould is greater than 90 °, so the side template is inclined, so for adapting the side template, the axial section of the side brush 31 is conical. Of course, in order to achieve the cleaning effect of the side mold brush 31, a wire brush is disposed on the outer circumferential surface of the side mold brush 31, and residues on the side wall of the cavity can be cleaned well when the side mold brush 31 rotates. In order to improve the cleaning strength and efficiency of the side die plate cleaning mechanism 3, a plurality of side die brushes 31 and a first driving mechanism 32 can be arranged at intervals along the length direction of the die cavity, and when the side die brushes 31 work together to clean the side walls of the die cavity. In addition, the moving plate 33 drives the first driving mechanism 32 and the side die brush 31 to move together along the transverse direction of the die cavity, so that the whole side die plate cleaning mechanism 3 moves together, the distance between the side die plate cleaning mechanisms 3 is adjusted, and the moving plate 33 and the moving platform 1 can be in sliding connection through a sliding groove and a sliding block. Preferably, the first drive mechanism 32 is a drive motor.

Preferably, the first distance adjusting mechanism 5 may be an air cylinder or a hydraulic cylinder, and may also be an elastic element such as a spring.

Further, the bottom die plate cleaning mechanism 2 comprises a support base 21 arranged below the moving platform 1, at least one bottom die brush 22 arranged below the support base 21 at intervals along the longitudinal direction of the die cavity, and a second driving mechanism 23 for driving the bottom die brush 22 to rotate; the bottom die brush 22 is rotatably and transversely erected on the support base 21, and the bottom die brush 22 is matched with the bottom of the mold cavity.

In the above structure, the bottom die brush 22 and the second driving mechanism 23 are supported by the support base 21, the bottom die brush is driven to rotate by the second driving mechanism 23, a rotation outer contour generating line of the bottom die brush 22 is the same as or substantially the same as a bottom contour line of the cavity, so that when the bottom die brush 22 contacts with the bottom of the cavity, the bottom surface of the cavity can be cleaned, and certainly, a plurality of bottom die brushes 22 can be provided, and the peripheral wall of the bottom die brush 22 is provided with the steel wire brush. Because bottom die brush 22 transversely erects in supporting seat 21 the horizontal direction of the axis of bottom die brush 22 towards the die cavity, and because there is side form board clearance mechanism 3 in the horizontal direction of die cavity, consequently, can't provide very big space in the die cavity and place second actuating mechanism 23, consequently, in this embodiment, the power output shaft of second actuating mechanism 23 can't directly be connected with bottom die brush 22 axial, so in this embodiment, adopt belt drive's mode drive bottom die brush 22 rotatory, be about to the supporting seat 21 top that second actuating mechanism 23 set up, connect the band pulley on second actuating mechanism 23's power output shaft, bottom die brush 22's one end stretches out supporting seat 21 and connects a band pulley equally, both connect through the wedge area. Preferably, the second driving mechanism 23 is a driving motor, but a transmission manner such as chain transmission or gear transmission may be adopted between the second driving mechanism 23 and the bottom die brush 22.

Furthermore, the bottom die plate cleaning mechanism 2 is connected with the moving platform 1 through a second distance adjusting mechanism 6, and the second distance adjusting mechanism 6 pushes the bottom die plate cleaning mechanism 2 to move in the vertical direction so as to keep the bottom die brush 22 in a contact state with the bottom of the die cavity.

In the above structure, in order to enable the bottom die plate cleaning mechanism 2 to adapt to square pile molds with different heights, the bottom die brush 22 is ensured to be in contact with the bottom of the mold cavity, and the cleaning function is realized, so that the second distance adjusting mechanism 6 lowers or raises the whole bottom die plate cleaning mechanism 2, the second distance adjusting mechanism 6 can be connected with the top of the supporting seat 21, and the second distance adjusting mechanism 6 can be a hydraulic cylinder or an air cylinder, or certainly can be an elastic element such as a spring.

In addition, the bottom form cleaning mechanism 2 further includes two corner cleaning mechanisms 24 disposed at two lateral sides of the supporting seat 21 and capable of moving along the lateral direction, the corner cleaning mechanisms 24 include a lateral sliding block 241 slidably connected to the supporting seat 21, at least one corner brush 242 disposed at the bottom of the lateral sliding block 241 along the longitudinal direction of the mold cavity at intervals, and a third driving mechanism 243 for driving the corner brush 242 to rotate, and a rotating outer contour generatrix of the corner brush 242 is adapted to the corner portions of the bottom form and the side form; the maximum lateral spacing between the two corner brushes 242 is less than or equal to the axial length of the bottom die brush 22.

When drawing of patterns after the precast pile shaping, the corner position between the die block board of square pile mould and the side form often can remain more concrete, this is because the volume increases slightly after the concrete condenses, and this corner position produces very big frictional resistance with the concrete after condensing to cause the concrete to remain in this corner position, consequently need get rid of remaining concrete, otherwise can influence the appearance of next root pile, can destroy its bearing capacity even.

Therefore, in the above structure, the corner cleaning mechanism 24 is disposed on the supporting seat 21, the height of the corner cleaning mechanism 24 can be raised or lowered together by the second distance adjusting mechanism 6 to ensure that the corner brush 242 can contact with the bottom formwork, the corner parts of the bottom formwork and the side formworks can be cleaned by the corner cleaning mechanism 24, wherein the transverse sliding block 241 can drive the corner brush 242 and the third driving mechanism 243 to move in the transverse direction to adapt to square pile molds with different cavity widths, and of course, the transverse sliding block 241 and the supporting seat can also be connected in a sliding manner by a sliding groove and a sliding block. In addition, the central axis of the corner brush 242 is perpendicular to the bottom plane of the mold cavity, and the rotating outer contour generatrix of the corner brush 242 during rotation is the same or substantially the same as the corner portions of the bottom mold plate and the side mold plates, because the corner portions of the bottom mold plate and the side mold plates are usually a round angle for facilitating demolding, the lower end of the corner brush 242 also has a round angle, of course, a plurality of corner brushes 242 can be arranged in the longitudinal direction to improve the cleaning efficiency, and a steel wire brush is arranged on the outer peripheral wall of the corner brush 242. In addition, the lower end of the side brush 31 may also have a rounded corner, so that the corner can be cleaned many times, thereby improving the cleaning effect. In addition, since the longitudinal length of the lower die brush 22 cannot be adjusted, the portion that cannot be cleaned by the lower die brush 22 may be cleaned by the corner brush 242. Preferably, the power output shaft of the third driving mechanism 243 may be directly connected to one end of the corner brush, and the third driving mechanism 243 may be a driving motor.

Furthermore, since the second distance adjusting mechanism 6 can only adjust the height distance between the corner cleaning mechanism 24 and the bottom form, but cannot adjust the distance between the two corner cleaning mechanisms 24, the two corner cleaning mechanisms 24 are connected by the third distance adjusting mechanism 7, and the third distance adjusting mechanism 7 pushes the corner cleaning mechanism 24 to move along the transverse direction of the mold cavity to keep the corner brush 242 in contact with the corner portions of the bottom form and the side forms.

In the above structure, the third distance adjusting mechanism 7 may be connected to the lateral sliding blocks 241 of the two corner cleaning mechanisms 23, and the corner brush 242 and the third driving mechanism 243 are driven to move together by pushing the lateral sliding blocks 241. Under the combined action of the second distance adjusting mechanism 6 and the third distance adjusting mechanism 7, the corner brush 242 can be kept in contact with the corner part. Preferably, the third distance adjusting mechanism 7 may be a hydraulic cylinder or an air cylinder, but may be an elastic element such as a spring.

In addition, in the actual production process, in order to facilitate demolding, the demolding agent is often required to be sprayed on the inner wall of the mold cavity after the mold cavity is cleaned, and the demolding agent is often sprayed manually in the prior art, so that the working efficiency is low. Therefore, the square pile mold cleaning device provided by this embodiment further includes a material spraying mechanism 8 disposed on the moving platform 1 or the bottom form cleaning mechanism 2, the material spraying mechanism 8 may be at least partially accommodated in the mold cavity, and in the process of the moving platform 1 moving, the mold release agent is sprayed to the molding surface of the mold cavity, and the material spraying mechanism 8 is located at the rear portion of the moving platform 1 in the cleaning direction.

In the structure, when the moving platform 1 drives the bottom template cleaning mechanism 2 and the side template cleaning mechanism 3 to move in the die cavity, the material spraying mechanism 8 can spray the release agent along with the backward-arranged advancing route of the moving platform 1, namely the release agent is sprayed while the bottom template cleaning mechanism 2 and the side template cleaning mechanism 3 are cleaned, so that the working time is greatly saved, and the working efficiency is improved.

Specifically, the material spraying mechanism 8 comprises a feeding pipe 81 connected with an external feeding mechanism and a U-shaped spraying pipe 82 connected with the feeding pipe 81, and a plurality of spraying ports 83 are arranged on the outer wall of the U-shaped spraying pipe 82 at intervals towards the mold cavity. In the above structure, the design of the U-shaped injection pipe 82 and the injection port 83 can make the release agent be evenly sprayed on the inner wall of the periphery of the mold cavity, thereby reducing the frictional resistance during the release.

In addition, the U-shaped injection pipe 8 may further be provided with a cleaning device (not shown) for blowing the cleaned concrete residue out of the mold cavity or shoveling the cleaned concrete residue out of the mold cavity, and the cleaning device may be an air nozzle or a shovel.
