Description

Technical Field

[0001] The invention relates to a live block separation device in a high-pressure forming device for a sanitary porcelain high-grade toilet product blank, in particular to a device for realizing the separation of live blocks inside a model. Background Art

[0002] At present, when the high-end toilet seat blank is formed by high-pressure grouting, it is necessary to set a live block inside the model to meet and ensure the tightness of its internal structure. In order to ensure the stability of the live block placed inside the blank model, the live block and the model are tightly fitted through a certain bonding adsorption force. When the model is demolded and opened, the traditional way to detach the live block is to use manual pulling. Due to the adsorption force between the live block and the model, the adsorption force becomes a resistance during the detachment process of the live block. If the manual live block detachment process is not smooth, it will cause poor detachment effect, and it is also easy to cause deformation or even damage to the blank, which has a great impact on the blank molding qualification rate and good product rate.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] See attached Figure 1-7 The disengagement device disclosed in the present invention is mainly suitable for disengaging the live blocks inside the model of the toilet blank high pressure forming machine, especially the live blocks used in the rear model.

[0028] The movable block detaching device is used in conjunction with the model mounting plate 10, and includes a mounting bracket 2, a pressure plate assembly, a push plate assembly and an airbag. The internal movable block 12, the rear model 11 and the model mounting plate 10 are horizontally assembled together in sequence, and a reserved hole 13 is provided on the rear model, and the reserved hole is used in conjunction with the ejector rod.

[0029] The mounting bracket is mounted on the outer side of the model mounting plate by bolts and other connectors. In this embodiment, the mounting bracket includes a rectangular plate body and an L-shaped bracket, and four brackets are arranged in groups of two and are arranged on both sides of the plate body. The ends of the brackets are mounted on the model mounting plate 10 by bolts and other connectors, and the plate body is mounted on the side of the model mounting plate.

[0030] The push plate assembly includes a push plate 3, a push rod 4, a guide hole 15 and a guide rod 14. The push plate is arranged on the inner side of the mounting bracket, and a horizontal push rod is provided on both sides of the push plate. The push rod is inserted into the reserved hole in the model, and its end contacts the internal slider; a guide hole is provided on both sides of the upper part of the push plate, and the guide hole is slidably matched with the guide rod fixed to the corresponding position on the inner side of the mounting bracket. As a preferred embodiment, the push plate is a polygonal structure, and in this embodiment, it is a hexagonal structure, wherein the width of the middle part is greater than the width of the mounting bracket plate body, and the push rod is vertically fixed to both sides of the middle part of the push plate. As a preferred embodiment, the end of the push rod is covered with a rubber sleeve. The end of the push rod directly contacts the side of the movable block.

[0031] In this embodiment, two side ears are provided on both sides of the upper middle part of the mounting bracket, and a guide rod is fixedly connected to the inner side of each side ear, and the free end of the guide rod touches the side surface of the model mounting plate. The guide hole on the push plate is slidably matched with the guide rod, and the push plate slides horizontally on the guide rod, thereby driving the push rod to move horizontally to realize the pushing of the movable block.

[0032] The airbag is arranged between the mounting bracket and the model mounting plate, and includes an inner airbag and an outer airbag; the upper end of the inner airbag is pressed on the upper inner side of the mounting bracket by the upper pressing plate, and the lower end of the inner airbag is pressed on the outer side of the model mounting plate below the mounting bracket by the lower pressing plate, and the lower part of the inner airbag is equipped with an inner air supply assembly; the upper end of the outer airbag is pressed on the upper inner side of the mounting bracket by the upper pressing plate, and the lower end of the outer airbag is pressed on the lower inner side of the mounting bracket by the middle pressing plate, and the upper part of the outer airbag is equipped with an outer air supply assembly, which passes through the mounting bracket. The intake and exhaust actions of the two airbags are opposite to each other to meet the forward and backward pushing action of the push plate together with the ejector rod.

[0033] In this embodiment, the outer airbag 5-2 and the inner airbag 5-1 are an integral airbag, and the upper part of the airbag is bent to form two inflatable spaces that are not connected to each other. The bending part is pressed to the inner side of the upper part of the mounting bracket by the upper pressure plate. The guide rod and the push rod are respectively arranged on both sides of the airbag. The inner air supply assembly and the outer air supply assembly have the same structure, both of which include an airbag nozzle and an air supply connector. The airbag nozzle is fixed on the airbag, one end of the air supply connector is connected to the airbag nozzle, and the other end is connected to the compressed air supply generator through a pipeline. As shown in the figure, the airbag nozzle in the outer air supply assembly passes through the mounting bracket and is connected to the outer airbag. The push plate is arranged between the inner airbag and the outer airbag. Under the push of the two airbags after inflation, the push rod is driven to move horizontally to realize the push of the movable block.

[0034] The operating principle of the device of the present invention is: when the rear mold opening action is executed, the outer air supply combination on the outer airbag supplies air, the outer airbag expands, and pushes the push plate together with the ejector rod to extend forward (to the left in the figure), so that the internal movable block is pushed away from the rear mold by a distance "L", so that the bonding adsorption force between the movable block and the rear mold is eliminated, thereby ensuring that the subsequent actions will not affect the blank; (See Figure 4 , 5 ); When performing the live block placement operation, the inner air supply combination of the inner airbag supplies air, the inner airbag expands, and pushes the push plate and the ejector rod back (to the right in the figure), ensuring that the combination between the internal live block and the rear model is accurately and reliably adsorbed in place (see Figure 3 , 5 ).
