Description

TECHNICAL FIELD

[0001] The utility model relates to ceramic green body laminating technical field, in particular to a device for ejecting laminating pin. BACKGROUND

[0002] In the multilayer ceramic preparation process, laminating forming is a key step before sintering, and needs to be accurately positioned through the pin on the laminating plate and the positioning hole of the casting sheet, and the ceramic green body is formed by the isostatic press. The traditional separation method relies on manual use of thin tongue depressor to pry the green body edge, and gradually separates the laminating plate and the green body. However, manual operation is difficult to control the uniformity of force, which is easy to cause local stress concentration of the green body, and causes bending deformation or microcracks. Such defects are further enlarged after high temperature sintering, causing product structure failure, circuit rupture and other problems, which seriously restricts the yield and reliability of multilayer ceramic devices.

[0003] Therefore, it is urgent to provide a mechanical pin ejection device to replace the manual separation method, to ensure that the green body is not damaged during the separation process after laminating, and to improve the production consistency and efficiency. UTILITY MODEL CONTENT

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a device with simple structure and efficient operation for automatically ejecting pins after multilayer ceramic laminating, to avoid green body deformation caused by manual separation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a device for ejecting laminating pins, comprising a support plate, a top plate, a top pin and a cylinder; the support plate is provided with through holes, the number and position of the through holes correspond to the pins on the laminating plate one by one, and the diameter of the through hole is greater than the diameter of the pin; the top plate is fixed with a top pin, the number and position of the top pin match the pin, and the diameter of the top pin is less than the diameter of the pin; the cylinder is fixed on the top plate, and is used to drive the top plate to drive the top pin to move vertically.

[0006] Further, the ratio of the diameter of the top pin to the diameter of the pin is 0.6-0.8.

[0007] Further, the cylinder is a double-acting cylinder, and the adjustable pressure range is 0.1-0.5 MPa.

[0008] Further, the top pin is made of hard alloy material (such as tungsten carbide), and the diameter tolerance is controlled within ±0.02 mm.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the cylinder drives the array of ejector pins to force synchronously, ensures that the ejection process is uniformly stressed, avoids local stress concentration caused by artificial prying, thereby eliminates the bending deformation of the ceramic green body and improves the product yield. The diameter of the ejector pin is smaller than that of the pin, only acts on the pin without contacting the ceramic green body, avoids tool scratching or extrusion and guarantees the integrity of the ceramic green body. The through hole design of the support plate realizes the collection and recycling of the pin, simplifies the operation process and improves the efficiency. BRIEF DESCRIPTION OF DRAWINGS
