Description

Lower mold elevating device for forming pulp mold container {Metal mold Elevatar of Molding System for Pulp Tray}

The present invention relates to a lower mold elevating apparatus used for a molding apparatus of a pulp mold container, and more specifically, a cylinder for elevating the lower mold and a drain pipe for discharging the pulp solution contained in the pulp solution tank to the outside of the pulp solution tank. The present invention relates to a lower mold elevating device for forming a pulp mold container, which facilitates repair and handling, achieves safe installation even in a small area, and prevents damage or failure from corrosion and coagulation of pulp.

Generally, a molding machine for molding a pulp mold container is provided with a lower mold which is housed in a pulp mold container and can mold a predetermined pulp mold container using a predetermined pulp solution.

The lower mold is configured to mold the pulp mold container through a process of being exposed upward in the pulp mold container by a cylinder rising and lowering in the vertical direction.

The lower mold is integrally connected to the cylinder to achieve the lifting operation by the piston movement, and the drain pipe for discharging the pulp solution of the pulp solution tank during pulp molding. Therefore, the pulp solution container can be molded by the pulp of the pulp solution adsorbed to the mold at the time of drainage while draining the pulp solution through the drain pipe so that molding can be completed through the molding die of the lower mold housed in the pulp solution tank. Then, the cylinder is operated to raise the lower mold so that the pulp mold container formed toward the upper mold (not shown) can be separated from the adsorption.

However, the conventional lower mold elevating device has a lower mold and a cylinder housed in a pulp solution tank, so that the tank is manufactured in a large size. Since the drain pipe for draining the pulp solution is also stored in the tank, it uses a flexible pipe (for example, a rubber pipe) to accommodate the operating range, resulting in a shorter service life. have.

The present invention has been devised to solve such a conventional problem, by installing a cylinder that can raise and lower the lower mold on the outside to reduce the unnecessary volume of the tank, protect the members from corrosion and solidification of the pulp, the service life To provide a low mold elevating device for forming a pulp mold container to attain a good repair and inspection at the same time.

The present invention for achieving the above object is a lifting device for lifting a mold accommodated in a cabinet-shaped pulp solution tank formed with a relatively deep receiving space, in the lower mold is disposed at a predetermined height in the pulp solution tank A drain pipe connected to the cylinder, a cylinder for raising and lowering the drain pipe and the lower mold integrally from the lower part of the drain pipe, a frame into which the rod of the cylinder is inserted and disposed at the bottom of the pulp solution tank and at least one fixed support installed therein. A lower mold elevating device for forming a pulp mold container including a conveyer which is fastened at both ends is lifted.

Here, it is preferable to further include a flexible connecting pipe connected to the outlet side of the drain pipe to rise and fall at any position on the vertical line.

Hereinafter, with reference to the accompanying drawings will be described in detail the lower mold lifting device for forming a pulp mold container according to the present invention.

1 is a cross-sectional view of the lower cylinder according to the present invention, Figure 2 is a cross-sectional view of the lower cylinder according to the present invention.

As shown in FIG. 1, the lower mold elevating apparatus has a cabinet-shaped pulp solution tank 10 having an entrance and exit opening in an accommodation space having a relatively predetermined depth, and through an entrance and exit opening of the pulp solution tank 10. The lower die 20 is provided at the bottom and is connected to the cylinder by the lower portion.

In the pulp solution tank 10, a pulp solution 12 containing 7% pulp and 93% solvent (water) is stored in a predetermined region of the receiving space. The pulp solution 12 is initially stored in a storage tank (not shown) and stored in the pulp solution tank 10 through a supply line. In one adjacent area of the pulp solution tank 10, an auxiliary water tank 14 is provided to receive and store the overflowed pulp solution 12 when the pulp solution 12 is excessively supplied.

The lower mold 20 is disposed at a predetermined height point from the bottom in the receiving region in the pulp solution tank 10 so as to be in contact with the pulp solution 12, and guides the inside of the pulp solution 12 when the pulp solution 12 is discharged. The solvent suction hole 22 is provided. The solvent suction hole 22 is formed of a plurality of long and thin strands penetrate the lower mold 20, one end is connected to correspond to the drain pipe (30).

The drain pipe 30 is disposed perpendicular to the bottom of the lower mold 20 and connected to the lower mold 20 on the upper surface thereof, and the lower surface thereof is connected to the cylinder 40. In addition, the drainage induction passage 32 is provided inside the upper portion is integrally connected to the lower mold 20 side and the lower side is opened so that the outlet 34 is provided. Outlet 34 is connected to the flexible flexible pipe 36 is adjustable.

The cylinder 40 is provided with a cylinder rod 42 which can be pulled out by a piston operation and vertically elevating operation. The cylinder rod 42 is provided on a conveyer 50 which is disposed on the upper side and is capable of raising and lowering. Is inserted into the upper side is connected to the lower end of the drain pipe (30).

The transfer table 50 is connected to the lower end of the fixing support 52 which is fixed to at least one of the lower ends of the frame 60 holding the pulp solution tank 10 so as to be able to move up and down. The fixing support 52 is fastened firmly and securely by the fixing means, the top and bottom is fixed so as not to shake or change.

The lower mold elevating device of the present invention is provided at the lower portion of the lower mold 20, the pulp solution 12 in the state in which the lower mold 20 is accommodated in the pulp solution tank 10, the pulp solution tank 10 It supplies to a predetermined amount, and then pulp solution 12 cabbages through the drain pipe 30. At this time, the pulp of the pulp solution 12 is adsorbed to the molding die 70 of the lower mold and the solvent (water) is discharged through the drain pipe 20 through the solution suction hole 22 of the lower mold 20. The pulp container is then molded.

When the cylinder 40 is operated to send the molded article thus formed to another process (drying and conveying), as shown in FIG. 2, the cylinder rod 42 is pulled out and raised, and the drain pipe 30 is raised to lower the mold 20. The ascending to the upper portion in the pulp solution tank 10 is formed to protrude to the outside, the molding is sent to another place through the adsorption and separation process by the upper mold (not shown).

Here, the cylinder rod 42 is inserted into the transfer table 50 connected to at least one fixed support 52 fixed to the frame 60 and connected to the drain pipe 30 to maintain a safe fixed state. The shaking does not occur so that safe use can be achieved. In addition, the driving stroke is good because it forms a vertical direction in a straight line according to the lifting stroke of the transport table (50).

On the other hand, the flexible connection pipe 36 is connected to the outlet 34 of the drain pipe 30 is variable according to the moving distance while moving up and down with the drain pipe 30 to achieve a safe drainage state by inducing drainage.

As described above, the present invention accommodates only the lower mold in the pulp solution tank and installs the other members externally, thereby minimizing corrosion and at the same time preventing failure or damage due to the pulp solidification and reducing unnecessary volume of the tank. It is possible to reduce the installation area and to achieve economical use by extending the service life with good repair and inspection.
