Description

Technical Field

[0001] This utility model relates to the field of corner protector molding technology, specifically a ceramic tile corner protector foam molding mold. Background Technology

[0002] Tile corner protectors are decorative materials used to protect the edges and corners of tiles. In construction and decoration, the edges and corners of tiles are easily damaged by collisions and friction. Tile corner protectors can effectively prevent this from happening. The principle of foam molding is to inject foaming material into the mold, and under certain temperature or pressure, the foaming material undergoes a chemical reaction or physical change, thereby forming a foam plastic product with a microporous structure. During the foaming process, the plastic material fills the mold cavity and expands. After foaming is completed, if the mold cannot be demolded smoothly, it may lead to quality problems such as product surface damage and deformation. For example, when manufacturing EPS foam packaging materials, if the mold is not demolded properly, the product edges and corners may be scratched by the mold, affecting its protective performance.

[0003] Chinese patent CN219360292U discloses an automatic forming mold for EPE corner protectors, comprising a base and a support frame. The support frame is equipped with an automatic forming structure, which includes a first outer shell. The upper surface of the first outer shell is fixedly connected to the inner wall of the support frame. An electric telescopic rod is fixedly connected to a vertical plate. The lower surface of a second rack is fixedly connected to a vertical rod. The vertical rod passes through the first outer shell and is slidably connected to a slide rail machined on the first outer shell. The surface of the support frame is fixedly connected to the surface of a material box. The upper surface of the material box is connected to the lower surface of the inlet. The surface of the material box is connected to a first discharge pipe, which passes through the support frame. Through the cooperation of the material feeding structure and the automatic forming structure, the corner protector mold is longitudinally fed, delivering material to each corner of the mold.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent uses the combination of a material feeding structure and an automatic forming structure to perform longitudinal material feeding of the corner protector mold, feeding materials to each corner of the mold, but it cannot automatically close and lock the upper and lower molds.

[0006] 2. This patent cannot utilize gravity and auxiliary devices for multiple assisted material unloading.

[0007] Therefore, those skilled in the art have provided a ceramic tile corner protector foam molding mold to solve the above problems. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model injects raw materials into the pressurizing component, the automatic closing component automatically closes the pressurizing component, and the self-locking component locks the automatic closing component, waiting for the raw materials to foam, cool and form. The output end of the servo reducer rotates 60 degrees to drive the triangular rotating block to rotate 60 degrees. The triangular rotating block rotates 60 degrees to drive the fixed frame of the automatic mold closing device to rotate 60 degrees. The fixed frame rotates 60 degrees to drive the pressurizing component, the automatic closing component and the self-locking component to rotate 60 degrees, so that the automatic mold closing device waiting to be formed rotates to the left station to wait for forming. At this time, the upper automatic mold closing device can be injected with raw materials. After the injection is completed, the upper automatic mold closing device is rotated to the left station to wait for forming. The automatic mold closing device at the left station rotates to the right to unload the material. The automatic unloading device assists the automatic mold closing device on the right to unload the material, which is conducive to the continuous forming of the corner protector.

[0019] 2. The extension of the third cylinder output end of the self-locking assembly drives the upper end of the rotating rod to move to the right, causing the lower end of the rotating rod to move to the left. This causes the rotating rod to rotate on the support bracket, pushing the slot on the lower side of the rotating rod to the fixed block position on the right side wall of the fixed frame, thus quickly locking the upper and lower molds. This facilitates automatic locking of the upper and lower molds. The extension of the second cylinder output end drives the extension plate to rotate. The rotation of the extension plate towards the lower mold causes the upper mold to rotate towards the lower mold, resulting in initial mold closing of the upper and lower molds. The upward movement of the first cylinder output end of the pressure assembly moves the lower mold upward. At this point, the lower mold is pressed against the upper mold of the automatic closing assembly, which further closes the upper and lower molds and increases the pressure between them, which is beneficial for automatic mold closing. The output shaft of the reduction motor of the cleaning assembly rotates, driving multiple circular cleaning brushes to rotate and sweep off the molded corner protectors that are stuck to the upper mold, so that they fall to the unloading port. The upper mold of the automatic mold closing device on the right opens, and the output end of the first cylinder shortens, driving the lower mold to move towards the fixed frame. At this point, the lower mold is pressed against the fixed frame, and the upper end of the fixed rod pushes out the molded corner protectors at the opening position, which is beneficial for material unloading. At the same time, gravity is used for demolding. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0028] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A ceramic tile corner protector foam molding mold includes a frame 1. A servo reducer 2 is fixedly installed on the rear side of the frame 1. A triangular rotating block 3 is rotatably connected to the upper side of the frame 1 via a rotating shaft. The rotating shaft of the triangular rotating block 3 is fixedly connected to the output shaft of the servo reducer 2. Multiple automatic mold closing devices 4 are installed on the triangular rotating block 3. An automatic unloading device 5 is installed on the front side of the frame 1. The automatic mold closing device 4 includes: a fixed frame 41, a pressure component, an automatic cover closing component, and a self-locking component. The fixed frame 41 is fixedly installed on the triangular rotating block 3. The pressure component is installed inside the fixed frame 41. The automatic cover closing component is installed on the left side wall of the fixed frame 41. The self-locking component is installed on the upper side of the fixed frame 41.

[0029] The raw material is injected into the pressurizing component, and the automatic lid-closing component automatically closes the lid of the pressurizing component. The self-locking component locks the automatic lid-closing component, and waits for the raw material to foam, cool, and form. The output end of the servo reducer 2 rotates 60 degrees, driving the triangular rotating block 3 to rotate 60 degrees. The triangular rotating block 3 rotates 60 degrees, driving the fixed frame 41 of the automatic mold-closing device 4 to rotate 60 degrees. The fixed frame 41 rotates 60 degrees, driving the pressurizing component, the automatic lid-closing component, and the self-locking component to rotate 60 degrees, so that the automatic mold-closing device 4 waiting to be formed rotates to the left station to wait for forming. At this time, the upper automatic mold-closing device 4 can be injected with raw material. After the injection is completed, the upper automatic mold-closing device 4 is rotated to the left station to wait for forming. The automatic mold-closing device 4 at the left station rotates to the right for unloading. The automatic unloading device 5 assists in unloading the automatic mold-closing device 4 on the right.

[0030] The pressurizing assembly includes: a first cylinder 42, a lower mold 43, and a fixing rod 44. The first cylinder 42 is fixedly installed inside the fixed frame 41. The lower mold 43 is slidably connected to the upper side of the fixed frame 41. The lower side of the lower mold 43 is fixedly connected to the output end of the first cylinder 42. The lower mold 43 is provided with multiple openings. Multiple fixing rods 44 are fixedly installed on the upper side of the fixed frame 41. Each opening is provided with a fixing rod 44. The upper side of the fixing rod 44 is slidably connected to the lower mold 43.

[0031] The raw material is injected into the opening of the lower mold 43 of the pressurizing component. The automatic closing component closes the lid automatically, and the self-locking component locks the automatic closing component. The output end of the first cylinder 42 moves upward, driving the lower mold 43 to move upward. At this time, the lower mold 43 is close to the automatic closing component, and the upper end of the fixing rod 44 is flush with the opening position. Wait for the raw material to be formed. This helps to increase the pressure between the molds, making the raw material easier to form.

[0032] The output end of the first cylinder 42 shortens, causing the lower mold 43 to move towards the fixed frame 41. At this time, the lower mold 43 is in close contact with the fixed frame 41, and the upper end of the fixed rod 44 pushes out the forming corner protector at the opening position, which is beneficial for assisting material unloading.

[0033] The automatic lid closing assembly includes: a fixed base 45, a second cylinder 46, an upper mold 47, and an extension plate 48.

The upper mold 47 is hinged to the left side of the fixed frame 41 via a hinge. The extension plate 48 is fixedly installed on the upper mold 47. The end of the extension plate 48 away from the upper mold 47 is rotatably connected to the output end of the second cylinder 46 via a rotating shaft.

[0034] The output end of the second cylinder 46 of the automatic lid closing assembly extends, causing the extension plate 48 to rotate. The extension plate 48 rotates towards the lower mold 43, causing the upper mold 47 to rotate towards the lower mold 43, so that the upper mold 47 and the lower mold 43 initially close. The output end of the first cylinder 42 of the pressurizing assembly moves upward, causing the lower mold 43 to move upward. At this time, the lower mold 43 is in close contact with the upper mold 47 of the automatic lid closing assembly, so that the upper mold 47 and the lower mold 43 further close, and at the same time increases the pressure between the upper mold 47 and the lower mold 43, which is conducive to automatic mold closing.

[0035] Example 2: In some embodiments, such as Figures 1-5In a preferred embodiment of this utility model, the self-locking assembly includes: a third cylinder 49, a support bracket 410, a rotating rod 411, and a fixing block 412.

A slot is provided on the lower side of the rotating rod 411, and the slot is located at the end of the fixing block 412 away from the fixed frame 41.

[0036] The extension of the output end of the third cylinder 49 of the self-locking assembly drives the upper end of the rotating rod 411 to move to the right, causing the lower end of the rotating rod 411 to move to the left, so that the rotating rod 411 rotates on the support bracket 410, pushing the slot on the lower side of the rotating rod 411 to the position of the fixing block 412 on the right side wall of the fixed frame 41, so that the upper mold 47 and the lower mold 43 are quickly locked, which is beneficial to the automatic locking of the upper mold 47 and the lower mold 43.

[0037] Multiple positioning rods 6 are fixedly installed on the fixed frame 41. The upper mold 47 and the lower mold 43 are slidably connected to the positioning rods 6, which helps to improve the clearance fit between the upper mold 47 and the lower mold 43.

[0041] The output end of the fourth cylinder 52 of the drive assembly extends, causing the rack 53 to move to the right. The rack 53 moving to the right causes the gear 54 to rotate, so that the gear 54 rotates the same angle each time.

[0042] The cleaning assembly includes: a discharge port 55, a rotating bracket 56, circular cleaning brushes 57, and a reduction motor 58. The discharge port 55 is fixedly installed on the right side of the support plate 51. The rotating bracket 56 is fixedly installed on the rotating shaft of the gear 54.
