Description

Full-series hydraulic demoulding and core pulling device for machining of sintered plate

Technical Field

The utility model relates to a mould board processing of burning, in particular to a full series of hydraulic pressure drawing of patterns core device for moulding board processing of burning.

Background

The plastic sintered plate is a more advanced filtering material and an air filter in the world at present, has the characteristics of high filtering precision, long service life, low maintenance cost, acid resistance, alkali resistance, corrosion resistance and the like, and is widely used in the fields of metallurgy, building materials, electric power, chemical industry, medicine, food, automobiles, national defense and the like.

The plastic sintered plate is produced by injecting powdery high molecular compound into a mold and sintering. The sintering process flow of the once-molded plastic-sintered filter plate is as follows:

1. mold cleaning: the inner cavity of the mould is wiped clean by lint without leaving any dust and impurities, and then the release agent is uniformly coated on the zigzag inner cavities of the upper mould and the lower mould and on each surface of the core rod.

2. Die assembly: the core rod is put into the lower die, the front end and the rear end of the core rod are positioned and fixed by the fixing plate and the positioning plate, so that the clearance of the core rod in the die is kept consistent, the upper die is closed, all the bolts are screwed, no gap is ensured among all the parts, and the material charging opening sealing plate is not assembled temporarily.

3. Feeding: the mould after the compound die is vertically placed on the vibrating table, the mixed powder is added into the feeding port, then the vibrating table is opened, the powder in the mould is uniform and compact through vibration, the vibrating table is closed at last, and the feeding port sealing plate is covered and the bolt is screwed down.

4. And (3) sintering: and (3) putting the mould added with the powder into a sintering furnace for heating, stopping heating the sintering furnace after the temperature rises to a set temperature value, and keeping the mould in the sintering furnace for heat preservation and firing according to the process requirement.

5. And (3) cooling: and taking the mold out of the sintering furnace after the mold reaches the specified heat preservation time in the sintering furnace, and then blowing air and spraying for cooling the surface of the mold to reduce the temperature of the surface of the mold to the temperature specified by the process requirement.

6. Demolding: and flatly placing the cooled mould on an operation table, extracting the core rod, screwing and opening the bolt to open the upper mould, taking out the primary molded and sintered plate formed in one step from the lower mould, and sintering.
