Description

Technical Field

[0001] This utility model belongs to the technical field of brick making equipment, specifically relating to a quick mold changing mechanism. Background Technology

[0002] Currently, fabric bricks are made by forming a layer of fabric on top of a brick. The fabric brick production process requires the combined operation of a brick forming machine and a fabric forming machine. In practice, the brick forming machine has a material feeding trolley at its inlet end to feed the base material into the mold frame; the fabric forming machine is located at the outlet end of the brick forming machine to feed the fabric material into the mold frame. Existing molds need to be mounted on a base frame, which moves the mold. When changing molds, the base frame needs to be removed, resulting in low efficiency. Therefore, this proposed solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a quick mold changing mechanism that can change molds without disassembling the moving base.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quick mold changing mechanism, including two movable base frames, two movable tracks, and a drive assembly. The two movable tracks are spaced apart, and the two movable base frames move on the two movable tracks respectively. Each movable track includes a first horizontal section, an inclined section, and a second horizontal section. The first horizontal section is connected to the lower end of one side of the inclined section, and the second horizontal section is connected to the upper end of the other side of the inclined section. The surface of the second horizontal section is provided with a clearance notch, which is inclined at the same angle as the inclined section. Each movable base frame includes a housing and two rotating wheels. The lower surface and two side end faces of the housing form openings. The rotating wheels are connected inside the housing. The drive assembly drives the movable base frame to move on the movable guide rail.

[0005] Furthermore, a fixed plate connects the two moving tracks.

[0006] Furthermore, the drive assembly includes two sets of drive bodies, which are respectively used to drive two movable base frames to move. Each drive body includes a drive wheel, a lifting guide wheel, a driven wheel, and a first chain. The first chain is sleeved on the circumference of the drive wheel, the lifting guide wheel, and the driven wheel. The diameter of the drive wheel is smaller than that of the driven wheel. The lifting guide wheel is located between the drive wheel and the driven wheel. The position of the lifting guide wheel corresponds to the inclined section. The movable base frame is fixedly connected to the first chain.

[0007] Furthermore, the drive assembly also includes a drive motor, a synchronizing rod is connected between the drive wheels of the two drive bodies, a gear ring is provided on the circumferential surface of the synchronizing rod, and a gear is provided at the output end of the drive motor. The gear and the gear ring are driven by a second chain.

[0008] Furthermore, a rotating shaft is provided on the inward-facing side of the movable base frame. The rotating shaft is located on the side of the housing near the drive wheel. A locking block is rotatably connected to the rotating shaft, and the locking block is fixedly connected to the first chain.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In this invention, the template is mounted on two movable base frames, and a drive assembly drives the movable base frames to move on a moving track. When the movable base frame is in its initial position, the rotating wheel at the rear of the movable base frame is located in the first horizontal section, and the rotating wheel at the front of the movable base frame is located within the clearance notch. At this time, the shell is stacked on top of the second horizontal section (the distance between the two is relatively small). The drive assembly starts to drive, and the rotating wheel at the rear of the movable base frame moves from the inclined section to the second horizontal section, and the rotating wheel at the front of the movable base frame moves from within the clearance notch to the second horizontal section. With the above settings, when mold changing is required, the movable base frame can be lowered to make way, eliminating the need to remove the movable base frame during the mold changing process, thus improving the overall mold changing efficiency.

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figure 1-5 As shown, this embodiment provides a quick mold changing mechanism, including two movable base frames 1, two movable tracks 2, and a drive assembly 3.

[0019] Two moving tracks 2 are spaced apart and correspond to each other on the left and right. A fixed plate connects the two moving tracks 2. The moving track 2 includes a first horizontal section 21, an inclined section 22 and a second horizontal section 23. The first horizontal section 21 is connected to the lower end of one side of the inclined section 22, and the second horizontal section 23 is connected to the upper end of the other side of the inclined section 22. A clearance notch 24 is provided on the surface of the second horizontal section 23. The clearance notch 24 is inclined and the inclination angle of the clearance notch 24 is the same as that of the inclined section 22.

[0020] Two movable base frames 1 are respectively located on two movable tracks 2. The movable base frame 1 includes a housing 11 and two rotating wheels 12. The circumferential surface of the rotating shaft 13 has an annular groove. The width of the annular groove is the same as the thickness of the moving track 2. The lower surface and two side end faces of the housing 11 have openings. The rotating wheels 12 are connected inside the housing 11. The rotating shaft 13 is provided on the inward side of the movable base frame 1. The rotating shaft 13 is located on the side of the housing 11 near the drive wheel 31. A locking block 14 is rotatably connected to the rotating shaft 13.

[0021] The drive assembly 3 drives the movable base 1 to move on the movable guide rail. The drive assembly 3 includes two sets of drive bodies, which are used to drive the two movable bases 1 to move respectively. The drive body includes a drive wheel 31, a lifting guide wheel 32, a driven wheel 33, a first chain 34 and a drive motor 35. A synchronizing rod 311 is connected between the drive wheels 31 of the two drive bodies. A gear ring is provided on the circumference of the synchronizing rod 311. A gear is provided at the output end of the drive motor 35. The gear and the gear ring are driven by the second chain. The first chain 34 is sleeved on the circumference of the drive wheel 31, the lifting guide wheel 32, and the driven wheel 33. The diameter of the drive wheel 31 is smaller than that of the driven wheel 33. The lifting guide wheel 32 is located between the drive wheel 31 and the driven wheel 33. The position of the lifting guide wheel 32 corresponds to the inclined section 22. The movable base frame 1 is fixedly connected to the first chain 34. Specifically, the locking block 14 is fixedly connected to the first chain 34. The rotating shaft 13 and the locking block 14 rotatably connected to the rotating shaft 13 can ensure that the movable base frame 1 can swing adaptively when driven by the driven component 3, so that the movable base frame 1 will not tilt during the movement.

[0022] Working principle: When the movable base 1 is in the initial position, the rotating wheel 12 at the rear of the movable base 1 is located in the first horizontal section 21, and the rotating wheel 12 at the front of the movable base 1 is located in the clearance notch 24. At this time, the housing 11 is stacked on top of the second horizontal section 23 (the distance between the two is relatively close). The drive component 3 starts to drive, and the rotating wheel 12 at the rear of the movable base 1 moves from the inclined section 22 to the second horizontal section 23, and the rotating wheel 12 at the front of the movable base 1 moves from the clearance notch 24 to the second horizontal section 23. With the above settings, when it is necessary to change the mold, the movable base 1 can sink to make way. During the mold changing process, it is not necessary to remove the movable base 1, which improves the overall mold changing efficiency.
