Abstract
Description
Technical Field
[0001] This utility model relates to the field of molds, and in particular to a ceramic blank press mold with a pressure feedback sensor. Background Technology
[0002] Mold making refers to the various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are important process equipment in industrial production used to shape products. Through a cavity or core of a specific shape, raw materials such as metals, plastics, rubber, and ceramics undergo physical or chemical changes under pressure, temperature, and other conditions to ultimately obtain parts or products with the desired shape, size, and properties. Molds are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, and ceramics. Molds have specific contours or internal cavity shapes. Using a contour shape with cutting edges allows the blank to be separated according to the contour line shape (blanking). Using the internal cavity shape allows the blank to obtain a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a punch and a die), which can be separated and joined. When separated, the part is removed; when joined, the blank is injected into the mold cavity for shaping. Molds are precision tools with complex shapes. They withstand the expansion force of blanks and have high requirements for structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.
[0003] A ceramic blank press mold is a mold used to make ceramic blanks. In the Chinese utility model patent "Announcement No.: CN222135368U, Name: A Demolding Device for an Alumina Ceramic Dry Press", it is found that by installing a main body mechanism, multiple blanks in the mold can be easily ejected, which improves production efficiency and reduces the labor intensity of workers. However, in the above application and existing technology, the formed material is generally ejected by ejector pins. However, ejector pins are prone to breakage during use, or excessive force can damage the material, affecting the yield of ceramic blanks and the efficiency of ceramic blank production.

A preheating wire disc 35 is provided above the heat-conducting plate 34, and the preheating wire disc 35 is connected to the top wall of the mounting groove.
[0044] In this technical solution, the preheating wire disc 35 can be used to preheat the upper mold body 31, thereby improving the production efficiency of ceramic blanks.
[0045] The lifting power assembly 5 includes a lifting plate 51, and a plurality of fixed columns 52 are connected to the bottom of the lifting plate 51. The bottom end of the fixed columns 52 is connected to the top of the upper mold body 31. The top of the lifting plate 51 is connected to a lifting device 53, and the top of the lifting device 53 is connected to the bottom of the top support block 21.
[0046] In this technical solution, the position of the distributed upper module 3 can be adjusted by the lifting power component 5.
[0047] The lifting plate 51 and the upper mold body 31 are each connected to two symmetrically distributed guide slide plates 54, which are slidably sleeved on the surface of the support guide column 22.

[0053] In this technical solution, the blocking ring plate 44 and the guide groove 45 are used to guide the mold closing of the upper mold body 31 and the lower mold body 41.
[0054] During manufacturing, the lifting device 53 is used to drive the lifting plate 51 to move down, thereby driving the fixed column 52 and the upper mold body 31 to move in the same direction. When the fixed column 52 and the upper mold body 31 move, the guide slide plate 54 moves in the same direction along the support guide column 22, so that the bottom of the upper mold body 31 is close to the bottom of the lower mold body 41 until the upper mold body 31 and the lower mold body 41 are in contact with each other. Then, the preheating spool 35 is used to heat the upper mold body 31. At the same time, the injection system and injection pipeline 32 are used to inject material into the distribution cavity 33. The heat from the preheating spool 35 can prevent the slurry entering the upper mold body 31 from getting cold and affecting normal flow. Then the slurry in the distribution cavity 33 enters the lower mold body 41 through the injection hole. The setting of multiple injection holes makes the injection more uniform and faster. Then, the lifting device 53 and the upper mold body 31 cooperate with the lower mold body 41 to form the ceramic blank; In the above process, pressure sensor 42 and pressure sensor 43 can detect pressure and provide feedback, which can improve the uniformity of the density of the pressed billet and reduce cracking defects.

[0056] In this technical solution, the multi-source ejection component 6 can be used to demold the ceramic blank through a combination of mechanical ejection and gas ejection.
[0057] The multi-source ejection assembly 6 also includes an air source 65, which is connected to the top of the support base 1.

The vertical outlet hole 68 and the side outlet hole 69 are respectively connected to the forming groove and the receiving cavity of the lower mold body 41.
[0058] In this technical solution, the gas source 65, the vertical outlet hole 68, and the side outlet hole 69 are used to assist in demolding the bottom and sides of the ceramic blank.
[0059] During demolding, the lifting power component 5 drives the upper distribution module 3 to move upward, and then the telescopic device 63 drives the ejector plate 61 to move upward, thereby driving the ejector pin 64 to move in the same direction, and using the ejector pin 64 to eject the ceramic blank in the lower mold body 41. Simultaneously, the gas source 65, gas distribution pipe 66, and inlet hole 67 are used to inject the material into the accommodating cavity of the lower mold body 41. Then, air is blown from the bottom into the lower mold body 41 through the vertical outlet hole 68 and from the side outlet hole 69 into the lower mold body 41, which loosens the ceramic blank and makes it easier for the bottom air blowing and the ejector pin 64 to eject the ceramic blank in the lower mold body 41, thereby improving the efficiency of mold demolding.
