Description

TECHNICAL FIELD

[0001] The utility model relates to automatic production technology, especially relates to dental impression production, specifically, it is a kind of dental cover automatic film press upper die sealing device. BACKGROUND

[0002] In the field of oral medical implant tooth technology, film press is widely applied in dental impression production preparation, the production preparation of dental impression, first needs the person who implants to bite out the model of tooth, then uses film press to press the membrane piece on dental impression and pours out the membrane piece model, then according to model makes dental arch model, and then dental arch model is pressed.

[0003] Due to the improvement of automation level and efficiency, it is necessary to replace manual film press with automatic film press, and manual film press uses single membrane piece, and automatic film press uses coiled material membrane piece for continuous generation, so it is necessary to solve the problem of automatic forming of membrane piece, and the automatic forming process is upper model cavity and lower die combined die, compressed air is passed into upper die to realize film pressing forming, and the sealing effect between upper model cavity and lower die will directly affect the forming effect, so it is necessary to provide sealing device for the upper die of dental cover automatic film press.

[0004] Therefore, it is necessary to provide a dental cover automatic film press upper die sealing device to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a dental cover automatic film press upper die sealing device.

[0006] A kind of dental cover automatic film press upper die sealing device, including upper model cavity, the lower surface of model cavity is provided with two layers of steps, called first layer step and second layer step, O-shaped sealing ring is arranged in first layer step, the depth of first layer step is less than the thickness of O-shaped sealing ring, O-shaped sealing ring is loaded into first layer step, and is limited by the inner side of first layer step, second layer step is provided with pressing plate, the inner side of pressing plate is inclined, and O-shaped sealing ring is pressed and fixed.

[0007] Further, the thickness of pressing plate is the sum of the depth of first layer step and second layer step.

[0008] Further, the first layer step is square.

[0009] Further, O-shaped sealing ring protrudes from the square sealing part of first layer step.

[0010] Further, compressed air is introduced into the upper model cavity, and high-sealing upper die structure is formed by pressing plate and square sealing part.

[0011] Further, the pressing plate is fixedly connected to the second layer step by the fixing member.

[0012] Further, the fixing member is a screw.

[0013] Compared with the prior art, the two steps are respectively provided with O-shaped sealing rings and pressing plates, the shape of the O-shaped sealing ring is changed, high sealing performance is formed, the sealing performance of the upper mold during tooth mold preparation is ensured, and the forming effect of the tooth mold is ensured.

[0017] Embodiment:

[0018] With reference to Figs. 1-3 , the embodiment shows a kind of upper mold sealing device of automatic film pressing machine of mouth guard, including upper model cavity 10, the lower surface of model cavity 10 is provided with two steps, called first layer step and second layer step, O-shaped sealing ring 20 is arranged in the first layer step, the depth of first layer step is less than the thickness of O-shaped sealing ring 20, O-shaped sealing ring 20 is loaded into first layer step, by the limit of first layer step inner side, after O-shaped sealing ring 20 is loaded, protrude first layer step is not less than 3-8mm, pressing plate 30 is arranged on the second layer step, the inner side of pressing plate 30 is inclined, and the pressure holding of O-shaped sealing ring 20 is fixed.

[0019] Wherein:

[0020] The thickness of pressing plate 30 is the sum of the depth of first layer step and second layer step.

[0021] The first layer step is square.

[0022] O-shaped sealing ring 20 protrudes first layer step part and forms square sealing part.

[0023] Compressed air is introduced into upper model cavity 10, and high sealing performance upper mold structure is formed by pressing plate 30 and square sealing part.

[0024] Pressing plate 30 is fixedly connected with second layer step by fixing member.

[0025] The fixing member is a screw.

[0026] Compared with the prior art, the two steps are respectively provided with O-shaped sealing rings and pressing plates, the shape of the O-shaped sealing ring is changed, high sealing performance is formed, the sealing performance of the upper mold during tooth mold preparation is ensured, and the forming effect of the tooth mold is ensured.

[0027] The above merely describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are all within the protection scope of the present application.
