Description

Technical Field

[0001] The utility model relates to the technical field of porcelain teeth, in particular to a metal porcelain product mold for removing processing bubbles. Background Art

[0002] Porcelain-fused-to-metal is a dental restoration technique that combines metal and ceramic materials to create crowns or bridges to repair damaged or missing teeth.

[0003] At present, when metal porcelain product molds are used to make teeth, bubbles are easily generated between the plastic porcelain raw material and the inner wall of the mold cavity, resulting in the injection-molded metal porcelain teeth containing bubbles after molding, affecting the production quality of the metal porcelain teeth. At the same time, after the existing metal porcelain product molds are completed for making teeth, the operator generally needs to use external tools to easily remove them, resulting in overly cumbersome demoulding and reducing the processing efficiency of the metal porcelain product molds.

[0009] Furthermore, a sealing gasket is fixedly connected to the bottom surface of the sealing plate.

[0010] Furthermore, the plurality of limiting sliding rods are all made of stainless steel.

[0011] Furthermore, mounting plates are fixedly connected to the lower sides of the left and right sides of the lower dental mold, and mounting holes are provided on the top surfaces of the two mounting plates.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model pours the plastic porcelain raw material into the interior of the lower tooth mold, uses external hydraulic equipment to fit the upper tooth mold tightly with the lower tooth mold, and then starts the dual-axis motor. The output end of the dual-axis motor drives the fan-shaped plate to rotate. The rotating fan-shaped plate pushes the transmission plate limited by the slide groove, slider and tension spring to move back and forth up and down through the indirect contact with the inner wall of the vibration chamber. The up and down transmission plate pushes the vibration plate to knock the upper side of the inner wall of the vibration chamber through the first spring, thereby removing the bubbles contained in the plastic porcelain raw material inside the lower tooth mold and improving the production quality of metal porcelain teeth. Later, when it is necessary to demould the device, the operator starts the air pump, and the air pump draws external air in and out through the air vent The inner wall of the air cavity, when the gas pressure inside the air cavity is too high, will push the sealing gasket and the sealing plate upwards, and the sealing plate pushes the ejector to push out the metal porcelain tooth made by this device, thereby quickly demolding the device. When the sealing plate moves upward, the second spring sleeved on the surface will be deformed by force. When the air pressure inside the air cavity is too low, the second spring will push the sealing plate and the ejector back to its original position under its elastic potential energy. This device can knock on the inside to avoid bubbles between the plastic porcelain raw material and the inner wall of the mold cavity, thereby improving the quality of the metal porcelain tooth made by this device. At the same time, this device does not require the operator to demold it through external tools. The demolding process is simple and convenient, thereby improving the processing efficiency of the device.

[0014] 2. The utility model utilizes the setting of the sealing gasket to improve the sealing performance of the sealing plate, making it easier for the gas inside the air cavity to push the sealing plate to move upward, thereby facilitating demoulding of the device.

[0015] 3. The utility model utilizes the setting of the mounting plate and the mounting holes, which can facilitate the operator to fix the device with external equipment through bolts, thereby improving the stability of the device during use and preventing the device from moving during use.
