Description

Technical Field

[0001] This utility model relates to the field of billet pressing technology, and more specifically, to a double-head billet pressing machine. Background Technology

[0002] Pressed blanks refer to unsintered blanks made from powder or ceramic clay through cold pressing, injection molding, or mechanical pressing. They are widely used in ceramic production and powder metallurgy. Depending on the material, they can be divided into ceramic pressed blanks and powder pressed blanks. Ceramic pressed blanks are formed by applying pressure to ceramic clay using a pressing machine, and are commonly used in the production of daily-use ceramics. Currently, when pressing ceramic clay or powder, the forming molds are generally fixed to the worktable using bolts or other equipment, resulting in poor ease of handling. Furthermore, most existing pressing machines operate in a single station, leading to generally low efficiency, and after pressing, it is difficult to quickly and stably demold the blanks.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a double-head pressing machine, which has the following beneficial effects:

[0016] 1. By setting up a hydraulic cylinder, pressure head, fixing ring, base, mold, limit frame, spring, and positioning block, when pressing ceramic blanks into shape, pulling the pull rod compresses the spring, installing the base into the fixing ring. Releasing the pull rod and resetting the spring pushes the positioning block into the positioning groove to position and fix the base and mold. Ceramic powder is added to the mold, and the hydraulic cylinder pushes the pressure cover and pressure head into the mold to press the powder into blanks. Through the cooperation of two sets of molds and pressure heads, staggered operation can be performed, effectively improving processing efficiency. Furthermore, the cooperation of the spring and positioning block allows for flexible and quick mold loading and unloading, facilitating rapid mold replacement.

[0017] Second, by setting a base plate, support rods and limiting rings, after the ceramic blank is pressed and formed, the mold is removed from the fixing ring and inverted. Then, the base plate is moved by pushing the support rods, so that the pressed ceramic blank can be removed from the mold and demolded. The operation is simple and convenient and has strong practicality.

[0018] Third, by setting up a vibrator, when adding ceramic clay or powder to the mold, the vibrator is started to apply vibration to the powder in the mold through the fixed ring and the base, thereby ensuring that the powder is added evenly and compactly in the mold, effectively improving the quality of ceramic blank pressing and molding.
