Abstract

The invention relates to a forming device for a pulp molding hollow product, which is characterized in that a lower half die 1 is arranged on a fixed stander 3, and an upper half die 2 can be lifted vertically under the drive of a cylinder 4 to finish operations of opening and closing the die; after the upper and lower half dies are closed, a vacuum valve 12 of an air chamber of the upper half die is opened, and then the air chamber 11 of the upper half die is communicated with an air chamber 14 of the lower half die through the vacuum valve 12 and a vacuum guide hole 13; and after a pumping vacuum tube 15 connected with the air chamber 14 of the lower half die is vacuummed, the air chambers 11 and 14 of the upper and lower half dies are in a vacuum state. Pulp is injected to a die cavity 6 formed after the upper and lower half dies are closed through an injection tube 5, moisture is pumped in the pulp so that fibers in the pulp are adsorbed on the surface of the die to form a wet blank of the hollow product, and all the moisture pumped by the upper and lower half dies is discharged through the unique pumping vacuum tube 15. The forming device simplifies the prior four-layer frame structure into one layer, cancels a pumping vacuum tube of the upper half die, enables the unique pumping vacuum tube and the stander to realize fixed connection, and cancels an open pulp tank so that the structure of the forming device for the pulp molding hollow product is greatly simplified, the probability of failure is obviously reduced, and the working efficiency is remarkably improved.

Description

A kind of paper mould hollow product shaped device

Technical field

The present invention relates to a kind of shaped device of paper mould hollow product.

Background technology

Like the disclosed utility model patent of publication number CN2614220 " narrow eck hollow pulp mold product forming machine "; This technology exists tangible weak point: 1, structure is too complicated, and actual complete machine has more than four layers of framework: the secondary framework that 1. main frame of lift cylinder is installed, 2. can go up and down, 3. be connected, install three grades of frameworks of folding mould cylinder with the secondary framework and 4. realize the level Four framework of mould open/close; 2, the vacuum hose that draws water moves up and down with mould, frangible gas leakage, and find that leak source and Shi Xiu compare difficulty; 3, go up female die and be connected with vacuum hose respectively, at least three of sums, the possibility that gas leakage takes place is bigger; 4, the easy at work generation paper pulp of uncovered stock tank splashes, and workman's operating environment is abominable.

Summary of the invention

In view of the existing in prior technology deficiency; The present invention be intended to propose a kind of will have now four story frame structures be reduced to have only one deck framework, cancellation upper mold section vacuum tube, female die (containing air chamber) and the female die vacuum tube that draws water that draws water is fixedly connected with frame, cancels the paper mould hollow product shaped device of uncovered stock tank simultaneously.

Technical solution of the present invention is achieved in that

The described paper mould hollow product of present technique scheme shaped device; The cylinder, vacuum line and the compressed air line that comprise female die folding in female die and air chamber, the driving; Difference from prior art is that its female die is installed on the fixed frame; But the action of folding mould is accomplished in upper mold section oscilaltion under air cylinder driven, and paper pulp injects through Grouting Pipe goes up the die cavity that forms behind the female die matched moulds.

Difference from prior art also is: after going up the female die matched moulds; Open upper mold section chamber vacuum valve; The air chamber of upper mold section promptly communicates with the air chamber of female die through upper mold section chamber vacuum valve and female die chamber vacuum guide hole; After the vacuum tube that draws water that joins with the female die air chamber imported vacuum, last female die air chamber promptly was all vacuum state, closed the passage that vacuum valve then goes up between the female die air chamber and was turned off.

Based on above-mentioned technological improvement; The further simplified structure of this programme: moisture in the suction paper pulp is so that the fiber in the paper pulp is that the vacuum tube that draws water of the wet base of hollow product only needs one at the die surface adsorption forming; And only link to each other with fixed female die air chamber, the moisture that last female die aspirated is all discharged through this vacuum tube that draws water.

Description of drawings

1 in accompanying drawing of the present invention, i.e. Fig. 1: the structural representation of a kind of paper mould hollow product shaped device of the present invention.

Among the figure: 1, the air chamber 15 of the vacuum guide hole 14 of female die 2, upper mold section 3, frame 4, cylinder 5, the air chamber 12 of going up the die cavity 6 that forms behind the female die matched moulds, Grouting Pipe 11, upper mold section, upper mold section chamber vacuum valve 13, female die air chamber, female die, vacuum tube draws water

The specific embodiment

A specific embodiments of said paper mould hollow product shaped device; The cylinder, vacuum line and the compressed air line that comprise female die folding in female die and air chamber, the driving; The female die 1 of hollow product shaped device is installed on the fixed frame 3; But the action of folding mould is accomplished in upper mold section 2 oscilaltion under cylinder 4 drives, and paper pulp injects through Grouting Pipe 5 goes up the die cavity 6 that forms behind the female die matched moulds.

Behind the last female die matched moulds; Open upper mold section chamber vacuum valve 12; The air chamber 11 of upper mold section promptly communicates with the air chamber 14 of female die through the vacuum guide hole 13 of upper mold section chamber vacuum valve 12 and female die air chamber; After the vacuum tube 15 of drawing water that communicates with female die air chamber 14 imported vacuum, last female

die air chamber

11 and 14 promptly was all vacuum state, closed the passage that vacuum valve 12 then goes up between the female die air chamber and promptly was turned off.

Moisture in the suction paper pulp is so that the fiber in the paper pulp is that the vacuum tube 15 that draws water of the wet base of hollow product has only one at the die surface adsorption forming; Link to each other with fixed female die air chamber 14, the moisture that last female die aspirated is all discharged through the vacuum tube 15 that draws water.

A specific embodiment of upper mold section chamber vacuum valve 12 is for adopting stingy cylinder push-and-pull truncated cone-shaped valve stifled to seal or to open the valve opening that has same conical surface on the air chamber wall.

The instance of Grouting Pipe 5 is fixed on the female die opening part for the stainless steel tube that the opening shape that forms behind end shape and the last female die matched moulds is coincide, and its upper end links to each other with high position slurry bucket through the Pneumatic three-way ball valve.
