Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of test piece forming, specifically relates to a ceramic tile joint sealant transverse deformation test piece forming device. BACKGROUND

[0002] When the traditional joint sealant transverse deformation test piece is formed, first, the polyethylene film is placed on the rigid cushion seat, then the A-shaped mold is placed on the rigid cushion, the joint sealant is applied in the mold, and the application is uniform. Then, it is placed on the shaking table and vibrated for 70 times, the A-shaped mold is removed, the B-shaped mold is pressed and the 100N weight is placed, and the excess joint sealant is scraped. After 1h, the weight is removed, and after 2d, the B-shaped mold is removed, and the test piece is placed in the standard required environment for curing.

[0003] However, the above-mentioned joint sealant transverse deformation test piece forming has the following disadvantages before the A-shaped mold is removed:

[0004] (1) Since the shaking table (vibrated for 70 times) required to be used is a device specially used for cement mortar fluidity test, the size of the table surface does not match the shape and size of the transverse deformation test piece, which causes relative displacement during vibration, and the vibration intensity is not the same, that is, the vibration uniformity is poor.

[0005] (2) The table surface of the shaking table has no fixing device, so the rigid cushion seat cannot be directly fixed on the table surface, and the A-shaped mold cannot be fixed on the rigid cushion seat, thus, the air bubbles cannot be eliminated during actual vibration, and small air bubbles exist in the test piece, which causes errors in the test results. SUMMARY

[0006] The utility model wants to solve the technical problem of overcoming the prior art, and provides an improved ceramic tile joint sealant transverse deformation test piece forming device.

[0007] To solve the above technical problems, the utility model adopts the following technical scheme:

[0008] A ceramic tile joint sealant transverse deformation test piece forming device, which comprises a shaking table device and an A-shaped mold, wherein the shaking table device comprises a table surface platform and a vibrator for periodically vibrating the table surface platform up and down, the A-shaped mold comprises a bottom mold plate and a plurality of mold cavities formed on the bottom mold plate, and in particular, the area of the bottom mold plate is larger than the area of the table surface platform, the forming device further comprises a positioning component between the table surface platform and the bottom mold plate, a clamping assembly installed on the bottom mold plate and capable of providing vertical positive pressure on each mold cavity, and a lock piece for locking the clamping assembly relative to the bottom mold plate, wherein the center line of the table surface platform and the center line of the bottom mold plate are kept coincident based on the up-down assembly positioning of the positioning component.

[0009] Preferably, the aligning component is an electromagnet, and the base plate is made of metal or has an attracting part at the bottom to match the electromagnet.

[0010] Further, the aligning component is multiple and arranged in an array around the center of the table platform. The center line coincidence rate is increased.

[0011] According to a specific implementation and preferred aspect of the present application, the vibrator comprises a base, a stand, a lifting rod mounted on the stand, a cam driving the lifting rod to move up and down to form vibration, and a motor, wherein the lifting rod is located in the middle of the table platform. The middle is aligned to make the vibration provided by the whole table platform more balanced.

[0012] According to another specific implementation and preferred aspect of the present application, the forming device further comprises a controller in signal or circuit communication with the vibrator and the aligning component. The vibration of the jump table and the electromagnetic attraction assembly are intelligently controlled based on the controller, so as to be intelligently controlled.

[0013] Preferably, the clamping assembly comprises an L-shaped frame rod rotatably mounted on the base plate, a pressing arm rod mounted side by side on the inner side of the L-shaped frame rod, and a pressing head mounted at the end of each pressing arm rod, wherein when clamping, the L-shaped frame rod is horizontally arranged, the pressing arm rods are arranged side by side and extend up and down, and the pressing heads are vertically pressed on the mold cavity. In this way, based on the rotation of the L-shaped frame rod, the pressing arm rods can be kept extending up and down to form the required vertical pressure.

[0014] Further, the L-shaped frame rod has two groups and is arranged side by side along the length direction of the mold cavity, the two groups are relatively fixed through a connecting rod, and the two groups of pressing arm rods and pressing heads are arranged in alignment, wherein the bottom surfaces of the pressing heads are arranged in flush. Based on the multi-point pressing, the stability of positioning is further improved to improve the vibration synchronization degree of the table platform and the A-shaped mold.

[0015] In some specific implementations, four pressing heads are arranged on each mold cavity, and the four pressing heads are arranged in a rectangular array. Further, the center of the rectangle formed by the four pressing heads is aligned with the center of the corresponding mold cavity up and down. Not only the pressing is stable, but also the distribution of the pressing points is balanced.

[0016] In addition, the locking member comprises a locking hook mounted on the connecting rod and away from the flipped end portion of the L-shaped frame rod, a locking rod rotatably mounted on the base plate and capable of matching the locking hook, and an operation handle capable of rotating the locking rod, wherein the locking rod can adjust and keep the locking hook from moving downward. The operation handle is flipped to form self-locking in the form of downward pulling of the hook, so as to ensure the firmness of clamping.

[0017] Thanks to the implementation of the above technical solutions, the present application has the following advantages compared with the prior art:

[0018] Existing methods for molding lateral deformation specimens of sealant, before removing the A-type mold, suffer from several drawbacks. The required vibrating table (70 vibrations) is specifically designed for testing the flowability of cement mortar, and its dimensions do not match the shape and size of the specimen. This mismatch causes relative displacement during vibration, resulting in inconsistent vibration intensity and poor compaction uniformity. Furthermore, the lack of a fixing device on the table prevents the rigid support from being directly fixed to the table, and the A-type mold cannot be secured to the rigid support. Consequently, air bubbles cannot be eliminated during vibration, leading to the presence of micro-air bubbles in the specimen and causing errors in the test results. This application addresses these shortcomings by comprehensively redesigning the specimen molding device, cleverly resolving the deficiencies of the existing technology. To address defects, this specimen molding device involves installing the A-type mold from the bottom template onto the desktop platform. Simultaneously, the alignment components ensure the centerline of the desktop platform aligns with the centerline of the bottom template for vertical assembly and positioning. Then, the clamping components press vertically onto each mold cavity, and the locking components lock the A-type mold itself. Finally, the vibration compaction operation is completed by the synchronous vibration of the jumping table and the A-type mold. Therefore, this invention, on the one hand, ensures the uniformity and consistency of the compaction process by aligning the centerlines of the alignment components and locking the A-type mold itself; on the other hand, the synchronous vibration of the jumping table and the A-type mold eliminates air bubbles inside the specimen, ensuring specimen thickness, improving result accuracy, and thus reducing the detection error rate.
