Detailed Description

The present utility model is described in further detail below with reference to the drawings to enable those skilled in the art to practice the utility model by referring to the description.

As shown in fig. 1 to 5, an embodiment of the present utility model provides a variable-size mold including: the mold comprises a mold bottom plate 1, wherein two groups of inserting grooves 7 and 8 are formed in the upper part of the mold bottom plate 1, the two groups of inserting grooves 7 and 8 are respectively arranged parallel to two first side parts of the mold bottom plate 1, and each group of inserting grooves comprises a plurality of inserting grooves; the four baffles and the die bottom plate 1 are mutually enclosed to form a cavity 6; the four baffles comprise two fixed baffles 2,3 and two movable baffles 4,5, wherein the two fixed baffles 2,3 are adjacent to each other and are respectively connected to two second side parts of the die bottom plate 1 through respectively corresponding first height adjusting structures, the two movable baffles 5,4 are respectively inserted into two inserting grooves which are respectively distributed into the two inserting grooves 7,8 through respectively corresponding second height adjusting structures, and one movable baffle 4 is a movable baffle selected from a group of movable baffles with different lengths.

The height and size of the die can be adjusted for processing ceramic tile foamed floors of different sizes. Specifically, the height of the fixed baffles 2,3 relative to the mold base plate 1 is adjusted by adjusting the first height adjusting structure, and the height of the movable baffles 4,5 relative to the mold base plate 1 is adjusted by adjusting the second height adjusting structure, thereby changing the depth of the cavity. The upper part of the mould base plate 1 is provided with two groups of inserting grooves 7,8, and the two groups of inserting grooves 7,8 are respectively parallel to the first side part of the mould base plate 1. The position of the movable baffle plate on the bottom plate 1 of the die can be changed by changing the inserting grooves in which the movable baffle plate is inserted, so that the size of the die cavity is changed. When the movable baffle is inserted into the insertion groove relatively close to the outer side, the area of the cavity can be increased; when the movable baffle is inserted into the insertion groove which is relatively close to the inner side, the area of the cavity can be reduced. A group of movable baffles with different lengths is provided, and the movable baffles with proper lengths are selected to be installed in one of the plugging grooves of one group according to the size of the cavity. That is, for two movable baffles 4,5, the length of one movable baffle 5 may be unchanged, and it may be selected to plug in any one of a corresponding set of plug-in slots, then another movable baffle 4 with a suitable length may be selected according to the interval between the first movable baffle and the opposite fixed baffle, so that the two fixed baffles 2,3 and the two movable baffles 4,5 may just enclose to form a closed rectangular box, thereby forming the closed cavity 6.

In a preferred embodiment, in the variable-size mold, the first height adjusting structure includes a long hole, a first screw hole and a fixing screw, the long hole is formed in the fixing plate and extends along the height direction of the fixing plate, the first screw hole is formed in the second side portion of the mold base plate 1, and the fixing screw penetrates through the long hole and is connected to the first screw hole in a threaded manner, so that the fixing plate is connected to the mold base plate 1.

Taking the fixed baffle 3 as an example, the relative positions of the fixed baffle 3 and the die bottom plate 1 are adjusted, the fixed baffle 3 is adjusted to a proper height, the depth of the cavity 6 reaches the requirement, the first screw holes are aligned with the corresponding positions of the strip-shaped holes 9, and the fixing screws penetrate through the strip-shaped holes 9 and are screwed into the first screw holes, so that the fixed baffle 3 and the die bottom plate 1 are fixedly connected. The position of the fixed baffle plate 3 is downwards adjusted, so that the depth of the cavity can be reduced when the die bottom plate 1 is aligned to the higher position of the fixed baffle plate 3; conversely, the depth of the cavity 6 can be increased by adjusting the position of the fixed baffle 3 upward to align the mold bottom plate 1 to a position lower than the fixed baffle 3.

The strip-shaped holes of the fixed baffle plate can be multiple and uniformly distributed on the fixed baffle plate. Correspondingly, the first screw holes are also multiple and are arranged corresponding to the strip-shaped holes.

Each fixed baffle is provided with a strip-shaped hole, and each second side part of the die bottom plate 1 is also provided with a second screw hole. The two fixed baffles 2,3 are connected to the mould base plate 1 in the same way.

In a preferred embodiment, in the variable-size mold, the second height adjusting structure includes a second screw hole, an adjusting screw, and a fixing nut, the second screw hole is opened at a lower side portion of the movable plate, extends along a height direction of the movable plate, the adjusting screw is screwed to the second screw hole, and a lower portion of the adjusting screw extends below the movable plate, and the fixing nut fixes the adjusting screw to the movable plate.

Taking the flapper 4 as an example, the adjusting screw 11 is provided at the lower side portion of the flapper 4, functioning like a leg. When the adjusting screw 11 is screwed outward, the length of the portion of the adjusting screw 11 exposed below the movable shutter 4 increases, the height of the movable shutter 4 with respect to the mold bottom plate 1 increases, and the depth of the cavity 6 increases. When the adjusting screw 11 is screwed inward, the length of the portion of the adjusting screw 11 exposed below the flapper 4 is reduced, the height of the flapper 4 relative to the mold bottom plate 1 is reduced, and the depth of the cavity 6 is reduced. The fixing nut 12 is used for tightening the adjusting screw 11 to prevent the adjusting screw 11 from shaking.

The number of the second screw holes on the movable baffle plate can be multiple, and correspondingly, the adjusting screws and the fixing nuts are also multiple and are arranged corresponding to the second screw holes.

Both movable baffles are provided with the same second height adjusting structure and are inserted into the die bottom plate 1 in the same mode.

Here, the upper end surfaces of the fixed and movable shutters should be flush after the height adjustment, and be positioned at the same height with respect to the horizontal plane.

In a preferred embodiment, in the variable-size mold, the widths of the two sets of insertion grooves 7,8 are equal to the two first side portions of the mold base plate 1 corresponding to each; the mould base plate 1 forms a plurality of projections 10 in the region where the two sets of plug grooves 7,8 are staggered with respect to each other.

In the area where the two groups of inserting grooves are staggered, a plurality of bulges are formed, and the interval between two adjacent bulges is equal to the width of the inserting groove.

In a preferred embodiment, in the variable-size die, teflon coatings are sprayed on the inner side surface of the baffle plate and the upper surface of the die bottom plate 1.

In the traditional production process, the polyurethane foaming agent generally has flash, so that polyurethane is adhered to a die and is very difficult to clean, and the product is not easy to demould. Therefore, the teflon coating is sprayed on the upper surface of the die bottom plate 1 and the inner side surface of the baffle plate to play a role of preventing the foaming polyurethane from adhering. The upper surface of the mold base plate 1 includes the upper surface of the area of the mold base plate 1 where the two sets of plugging grooves are not provided and the surface of the plugging grooves.

In a preferred embodiment, the upper ends of the two sets of slots 7,8 and the upper surface of the region of the mould base 1 where the two sets of slots are not provided together define the lower end face of the mould cavity 6, the lower end face 6 of the mould cavity being an inclined surface.

In practical application, the floor in the wet area of the assembled bathroom needs to be made into a drainage gradient. However, the existing ceramic tile foam floor has a large number of flat plate structures, the surface of which is horizontal and has no drainage gradient, and cannot be directly applied to the wet area of the assembled bathroom. To solve this problem, the present utility model is designed to make the upper end of the insertion groove in the mold base plate 1 and the lower end face of the cavity defined by the planar area in the mold base plate 1 together be an inclined surface. The ceramic tile foaming floor produced by using the die can be used for producing the ceramic tile foaming floor with gradient, and can be directly used in the wet area of the assembled bathroom.

In a preferred embodiment, in the variable-size mold, the lower end surface of the cavity 6 is arranged obliquely from low to high along a diagonal direction formed by a first apex where the two first sides intersect each other and a second apex where the two second sides intersect each other. As shown in fig. 2 and 4, the direction indicated by the arrow is the gradient direction.

The operation of the variable size mold is described below.

First, the size and depth of the cavity 6 in the mold are adjusted according to the size of the tile foamed floor to be processed. As shown in fig. 7 and 8, a base plate and a tile are further laid in the mold cavity 6, a cavity is formed between the base plate 19 and the tile 16, and a polyurethane foaming agent is injected into the cavity. Thereafter, as shown in fig. 6, the mold 14 is placed in the laminator 13 and heated, and the mold is heated. The temperature of the mould can increase the fluidity of polyurethane, and prevent insufficient foaming and material shortage caused by too fast cooling in the flowing process of polyurethane. After the foaming of the polyaramid grease is completed, the die 14 is removed from the laminating machine 13, one of the movable baffles is removed, and the ceramic tile foaming floor 15 with the gradient is pushed out from the direction of the movable baffle. Here, the removable shutter is slightly longer than the mold, facilitating the demolding operation.

As shown in fig. 7 and 8, the tile foamed floor 15 includes four layers of tiles 16, a steel wire mesh layer 18, a sealing sponge 17, and a bottom plate 19. The bottom plate 19 is a square frame structure, and has a frame around its periphery, and the steel wire mesh layer 18 is embedded into the bottom plate. The gradient direction of the tile foamed floor, i.e. one diagonal direction of the tile foamed floor, is also the corresponding diagonal direction of the bottom plate. The two frames connected to the starting point B of the diagonal line of the bottom plate are referred to as a first frame 25 and a second frame 26, respectively, the frame connected to the second frame 26 is referred to as a third frame 27, and the frame connected to the third frame 27 is referred to as a fourth frame 28. The heights of the first frame 25 and the second frame 26 at the starting point B are equal, and the heights of the first frame and the second frame are gradually reduced from large to small; the height of the connection part between the lowest end of the second frame 26 and the highest end of the third frame 27 is equal, and the height of the third frame 27 is gradually reduced from large to small; the height of the connection part of the lowest end of the first frame 25 and the highest end of the fourth frame 28 is equal, and the height of the fourth frame 28 is gradually reduced from large to small; the lowest end of the third rim 27 and the lowest end of the fourth rim 28 are connected to each other at the end point C of the diagonal line of the bottom plate. Therefore, the top surface of the bottom plate defined by the four frames of the bottom plate is inclined relative to the horizontal plane, and the ceramic tile foam floor is put into a die to be processed into the ceramic tile foam floor with gradient. The steel wire mesh layer 18 is a net structure for enhancing the overall rigidity and bending strength of the ceramic tile, the steel wire mesh plane supports the lower surface of the ceramic tile layer, and the periphery of the steel wire mesh plane is provided with supporting legs which are bent downwards and extend to the bottom plate. When the steel wire mesh layer 18 is embedded inside the bottom plate 19, the bottom plate 19 still has fillable cavities inside. The sealing sponge 17 covers the upper part of the bottom plate 19, and the periphery of the sealing sponge 17 is adhered with the peripheral frames of the bottom plate 19 through an adhesive. The ceramic tile layer is laminated above the sealing sponge, and the ceramic tile is bonded with the sealing sponge through an adhesive. During processing, polyurethane foaming agent is injected into the inner space of the bottom plate 19, and the ceramic tile foaming floor 15 is produced under the action of the laminating machine 13 and the die 14. The produced tile foam floor 15 with gradient is shown in fig. 9, and the direction indicated by the arrow is the gradient direction.

The ceramic tile foaming floors with the slopes can be spliced together to manufacture the spliced floor. As shown in fig. 10, four tile foam floors 20,21,22,23 of different heights are selected to ensure that the height of the joined edges of two adjacent tile foam floors is uniform, such as the highest edge of a first tile foam floor 20 being the lowest edge of a second tile foam floor 21, thereby ensuring that the slope of the resulting joined floor is continuous, smooth and excessive. The direction indicated by the arrow in fig. 10 is the gradient direction. During construction, the back of the ceramic tile foaming floor is coated with ceramic tile glue, then the ceramic tile foaming floor is paved in a waterproof disc, and the ceramic tile foaming floor is kept at a distance of about 30mm away from the water retaining edge of the waterproof disc 24 and is used for installing color steel wallboards subsequently. And after the tile glue is solidified, coating a joint beautifying agent at the joint, and thus, the installation of the spliced floor is completed.

In summary, the size-variable die provided by the utility model is adjustable in width, length and height, can finish the production of ceramic tile foaming floors with various specifications in one set of device, reduces the number of dies and die changing time, reduces the storage positions of the dies, improves the production efficiency of products, and saves the die cost. In addition, the variable-size die provided by the utility model can be used for producing the ceramic tile foaming floor with the gradient, and has the advantage of convenience in demoulding.

Although embodiments of the utility model have been disclosed above, they are not limited to the use listed in the specification and embodiments. It can be applied to various fields suitable for the present utility model. Additional modifications will readily occur to those skilled in the art. Therefore, the utility model is not to be limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
