Description

Lubricant recovery feeder of injection molding machine {A DEVICE FOR RECLAIMING AND SUPPLYING A LUBRICANT IN AN INJECTION MOLDING DEVICE}

The present invention mainly relates to a lubricating oil supply device for continuously supplying lubricating oil to the friction part where friction action occurs during the operation of an injection molding machine that manufactures a product by molding a synthetic resin material.

In particular, the present invention relates to a lubricant regeneration supply device for collecting the pre-supplied lubricant oil to remove the residue and water and then resupply the friction part.

It is well known that an injection molding machine is a dedicated machine used to make a hand made article using a mold made to make a specific article.

Such an injection molding machine inevitably generates frictional action between the devices as the material supply means for supplying the supplied water support material into the mold and the release means for detaching the finished article are inevitably driven. Lubricant is supplied to the friction part as a means to make the friction action progress rhythmically.

Lubricant oil supplied for this purpose not only plays a role of preventing premature wear of the friction part, but also plays a role of maximizing the life of the device and minimizing the failure factor. Therefore, continuous supply to the friction part is required.

A pumping device for forcibly supplying lubricating oil has been devised as a means for supplying lubricating oil to such a friction part, but such a conventional supply device must bear the economic loss of collecting and discarding the lubricating oil supplied to the frictional part once. As it is not widely used as a bar,

For example, there was a difficulty in reuse because it was mixed with lubricating oil collected from the friction part. On the other hand, the cooling water supplied to the lubricating oil as a cooling means for rapidly cooling the molten raw materials supplied into the mold. As they were mixed, they had difficulties that could not be reused.

The present invention has been researched and developed in consideration of the present situation, and it provides a step-by-step filtering means to the lubricating oil collecting means that is collected after being supplied and additionally installs a feeding-and-separating means using the characteristics of oil having a lower specific gravity than water. By providing a lubricating oil regeneration supply device of a simple principle to continuously supply only refined lubricating oil to the friction part,

In addition to minimizing the economic loss caused by minimizing the consumption of lubricating oil, it is possible to continuously supply lubricating oil to the friction part, thereby minimizing the wear phenomenon, and thus extending the life span and minimizing the failure factor. It is a technical problem of the present invention.

The present invention for achieving the above object,

The lubricating oil is supplied after the supply to the frictional portion and the lubricating oil is supplied to the frictional portion is supplied with a lubricating oil collection tank is discharged after the combination is composed of a main body 10 is covered with the lid (1).

The lid body 1 is formed by forming a collection tank 3 on the upper side for the first time to collect the lubricating oil flowing out through the lubricating oil outflow pipe 2, as shown in Figure 1, the bottom of the collection tank 3 The surface 3 'is formed to be inclined to one side, and at the end of the inclined bottom surface 3', a plurality of through holes 4 are formed to penetrate the lubricating oil vertically downwards, while the front of the through hole 4 is forward. On the bottom end (3 ') of the collecting tank (3) to form a catch end (5) to form a catch end (5) in the installation of a conventional filter (6) to achieve a primary filter means.

As shown in FIGS. 2 to 5, the main body 10 on which the lid 1 is covered is first to sixth input chambers 11 using diaphragms 21, 22, 23, 24, and 25. , 12, 13, 14, 15, 16), where appropriate,

The first input chamber 11 is partitioned by using a diaphragm 21 directly below the through-hole 4 formed in the collection tank 3 of the lid 1,

A space 21a is formed between the lower end of the diaphragm 21 and the bottom plate 10 'of the main body 10 so that the second input chamber 12 and the first input chamber 11 communicate with each other. In the bottom portion of the second input chamber 12 formed between the diaphragm 21 and the diaphragm 22, a lactation separating means 30 made of a float is additionally installed.

The lubricating oil inflow into the third input chamber 13 partitioned on the side of the second input chamber 12 through the diaphragm 22 and the diaphragm 23 forms a part of the end of the diaphragm 22 to lower the space 22a. ) To make it happen,

On the diaphragm 23, the inlet 31 is positioned on the third input chamber 13 side, and the outlet 32 is located on the fourth input chamber 14, where the conventional filter 33 is assembled and installed. It is configured to form a secondary filtering means.

The lubricating oil inflow into the fifth input chamber 15 partitioned behind the outermost end via the diaphragm 24 and the diaphragm 25 is realized by forming a lower portion of the diaphragm 24 to provide a space 24a. Meanwhile, a space 25a is formed between the lower end of the diaphragm 25 and the bottom plate 10 'of the main body 10 so that the fifth input chamber 15 and the sixth input chamber 16 communicate with each other. In the sixth input chamber 16 where the refined lubricant oil is finally collected, the suction port 40 'of the pump 40, which is installed as a forced oil supply means, is placed in the lid 1 to the frictional part. It is configured to realize continuous lubricant supply.

Reference numeral 41 denotes a discharge cock for cleaning.

Meanwhile, as shown in FIGS. 6 and 7, the feeding and separating means 30 additionally installed in the second input chamber 12 couples and installs a hollow fastener 50 in which the water outlet 51 is assembled. and,

Above the fastener 50, a small fitting 52 is inserted into the interior space 53 'and at the same time, a fastener 53 having a plurality of outlet holes 54 formed therethrough is installed and installed on the lower portion.

The buoy 55 is provided on the outside of the fixture 53 in a flowable state, but a connecting pin 56 is installed between the buckle 55 and the small buckle 52 inside the fixture 53 to provide buoyancy of water. In the synergistic action of the buoy 55 by the small buoy 52 is raised at the same time is configured to open the outlet hole 54 is formed through the fixture 53 to open.

The floats 52 and 55 used herein are preferably manufactured by using a polyester-based material that emerges when buoyancy occurs above a set value due to a lower specific gravity than water.

Lubricating oil regeneration supply device of the present invention having such a configuration is supplied to the friction action site of the injection molding machine (not shown) by the forced supply of the lubricating oil of the pump 40 fixed to the lid 1, the lubricant oil outlet pipe The lubricating oil recovered through (2) is executed from the step of introducing into the collection tank 3 of the lid 1.

At this time, the lubricating oil recovered by the collection tank 3 is inevitably mixed with the residue and water generated during the operation of the injection molding apparatus.

As such, the lubricating oil introduced into the collection tank 3 as water and debris is naturally moved downward along the inclined bottom surface 3 'after the primary debris action is realized through the filter 6. At the same time as the end portion is moved beyond the locking end 5, the drop is transferred to the first input chamber 11 of the main body 10 located directly below through the through hole 4. In this process, debris, which is heavier than lubricating oil, is caught by the filter 6, the inclined bottom surface 3 'and the front end 5, and the primary residue filtering action is naturally performed.

The lubricating oil in which the residue is filtered through the above process flows into the first input chamber 11 of the main body 10 and at the same time, partitions the first input chamber 11 and the bottom of the diaphragm 21 and the main body 10. It is introduced into the second input chamber 12 through the space (21a) formed between the plate (10 '), the lubricating oil at this time maintains a state in which the residue and the water is not filtered. Therefore, the lubricating oil introduced into the second input chamber 12 has a pure lubricating oil having a lower specific gravity than the water in the upper layer, and a relatively high specific gravity of the water in the lower layer, thereby naturally separating the water and the lubricating oil. When the water level in the lower layer is gradually increased through the feeding and separating action, the movement from the uppermost layer of the lubricant present in the upper layer to the third input chamber 13 through the space 22a provided on the diaphragm 22 is performed. The lubricating oil introduced into the third input chamber 13 by the continuous lubricating oil transfer action is introduced through the inlet 31 of the filter 33 installed on the diaphragm 23 and then the fourth input chamber 14. Through the outlet 32 of the filter 33 is located in the fourth input chamber 14 is introduced, and in this process, the residue filtering action remaining in the lubricating oil is repeatedly executed.

The lubricating oil introduced into the fourth input chamber 14 through the above process is carried out into the fifth input chamber 15 through the space 24a provided in the diaphragm 24 from the upper layer, and then the diaphragm 25 and Through the space 25a provided between the bottom plate 10 ′ of the main body 10, the inflow into the sixth input chamber 16 is repeatedly performed continuously. 40 ') is re-supplied to the lubrication target part of the injection molding apparatus by the forced pumping action of the pump 40 located in the sixth charging chamber 16, so that the lubricating oil supply action to the frictional part is continued. It will be done.

On the other hand, when the water level existing in the lower layer of the second input chamber 12 is higher than the set value by the repeated feeding separation action, the buoy 55 is naturally floated by the buoyancy of the water, at this time connecting pin 56 As the small spherical 52 coupled to each other through the floating at the same time, the outlet hole 54 formed through the fixing unit 53 is opened to naturally discharge the water located in the lower layer, and the water discharge is performed to some extent. If the buoyancy is lowered while the water level is lowered, the process of returning the floats 55 to their original positions is repeatedly performed, thereby discharging the water.

As described above, the present invention is designed to continuously lubricate the supply target area while regenerating the lubricant used in the injection molding apparatus, so that it can be reused repeatedly without consuming expensive lubricant. Not only did it significantly reduce the burden, but it also allowed the user to take advantage of maintenance while eliminating the need for lubricating oil management, as well as minimizing the wear and damage rate of the frictional parts due to the continuous supply of lubricant. It is a useful design that can be expected to achieve the effect of extending the service life.
