Technical Field

[0001] This utility model relates to the field of pulp molding technology, specifically to a pulp molding die. Background Technology

[0002] Pulp molding dies are the core tools in the production of pulp molded products. Their design precision and manufacturing quality directly affect the shape, dimensional accuracy, surface quality, and production efficiency of the products. A pulp suspension is poured onto the mold surface, and a vacuum pump is used to extract air from the back of the mold, causing the pulp fibers to be evenly adsorbed onto the mold cavity surface, forming a wet preform, which is then dried and shaped.

[0003] Existing pulp molding dies are not conducive to quickly absorbing moisture from the pulp in the molding cavity to improve the molding rate, and are not conducive to automatically ejecting the molded pulp to avoid mold jamming problems. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a pulp molding die. The pulp molding die facilitates the rapid absorption of moisture from the pulp in the molding cavity, thereby increasing the molding rate. It also facilitates the automatic ejection of the molded pulp, avoiding the problem of mold jamming.

[0005] The technical solution adopted by this utility model to solve its technical problem is a pulp molding die, including a base plate, an outer shell and an outer mold. The outer shell is installed on one side of the top of the base plate through a supporting vertical plate, and the outer mold is sleeved inside the outer shell. A sealing cover mold is engaged at the top of the outer mold. A pusher cylinder is installed on the top of the base plate through a mounting seat. The top output shaft of the pusher cylinder is connected to a hollow core mold through a connecting plate, and a rectangular sealing sleeve is sleeved at the bottom of the hollow core mold. The hollow core mold has water suction holes evenly distributed on its outer side and at the top of the rectangular sealing sleeve. The hollow core mold is wrapped with a rectangular wire mesh cover at the top of the rectangular sealing sleeve. A vacuum pump is installed on the top of the base plate and at one end of the push cylinder via a mounting base. The input port of the vacuum pump is connected to the output port at the bottom of the hollow core mold via a suction hose.

[0006] By adopting the above technical solution, the pulp molding die can quickly absorb the moisture in the pulp in the molding cavity, improve the molding rate, and automatically eject the molded pulp, avoiding the problem of mold jamming.

[0007] Specifically, locking bolts are installed at the top corners of the sealing cover mold through screw holes, and screw holes corresponding to the locking bolts are opened at the top corners of the outer mold.

[0008] Specifically, the top middle part of the sealing mold is connected to a pulp injection port, and an injection valve is provided at the top of the pulp injection port.

[0009] By adopting the above technical solution, the injection valve is opened and the prepared pulp is injected into the outer mold under high pressure through the pulp injection port.

[0010] Specifically, a control valve is provided on the suction hose and close to the hollow core mold.

[0011] By adopting the above technical solution, the control valve is opened to connect the vacuum pump power supply, and a vacuum is drawn into the hollow core mold to generate negative pressure inside.

[0012] Specifically, the rectangular sealing sleeve is located at the bottom of the outer mold, and the hollow core mold with water absorption holes is located inside the outer mold.

[0013] The beneficial effects of this utility model are: (1) The pulp molding mold described in this utility model is to fasten the sealing cover mold to the top of the outer mold, tighten the locking bolt to achieve quick positioning, open the injection valve and use the pulp injection port to inject the prepared pulp into the outer mold under high pressure, and form a pulp molding cavity between the outer mold, the sealing cover mold and the hollow core mold. Open the control valve to connect the vacuum pump power supply, and vacuum treatment is performed in the hollow core mold to generate negative pressure inside. The water suction hole is used to quickly absorb the water in the pulp in the molding cavity and improve the molding rate.

[0014] (2) The present invention provides a pulp molding mold, and uses a rectangular wire mesh cover to filter water to prevent all the pulp from being sucked out. Finally, the water is discharged through a vacuum pump. Loosen the locking bolts to remove the sealing cover mold, and use the push-pull electric cylinder to drive the hollow core mold to move upward, so as to automatically push out the molded pulp and avoid the problem of mold jamming.
