That is, when the first compression unit 210 moves forward and comes into contact with the second compression unit 220, an impact due to compression can be absorbed.

The elastic member 230 may be formed of a spring, elastic rubber, or the like, and is preferably formed of a material such as urethane or ethylene propylene diene in order to evenly apply a load to the second compression unit 220 .

An LED sensor 240 is formed at one point of the second crimping part 220, and through the LED sensor 240, whether the first crimping part 210 is operating or not and whether the first crimping part 210 is operating is completed or not is detected. Able to know.

At this time, the operation of the first compression unit 210 means that when the workpiece 10 is positioned between the first compression unit 210 and the second compression unit 220, the first compression unit 210 moves forward. This means that the workpiece 10 is pressed by the first compression unit 210 and the second compression unit 220 .

For example, when the first crimping unit 210 is in operation, the LED sensor 240 is lit in red, and when the charging of the first crimping unit 210 is completed, the LED sensor 240 is lit in green. .

In addition, although not shown in the drawing, a detection sensor (not shown) is configured inside the second compression unit 220 .

When the workpiece 10 is inserted between the first compression unit 210 and the second compression unit 220, a detection sensor detects the workpiece 10 and generates detection information.

The detection sensor is a method capable of controlling the device by detecting the motion or presence of the workpiece 10, and the method of detecting the motion uses a PIR (Passive Infra Red) sensor and uses sensors such as security It is applied to cameras, etc.

FIG. 3 shows the first compression unit 210 when it moves backward, and shows the first shape of a mold processing apparatus using a hydraulic cylinder according to the present invention.

The first cylinder 130 can move forward and backward, and when the first cylinder 130 moves forward, the first compression part 210 comes into contact with the second compression part 220 and the first compression part 210 comes into contact with the second compression part 220. The workpiece 10 seated between the 210 and the second compression unit 220 is compressed.

That is, the first cylinder 130 is coupled to one end of the first compression unit 210 to provide force for the first compression unit 210 to press the second compression unit 220 forward.

When the molding of the workpiece 10 is completed, the first cylinder 130 coupled with the first compression unit 210 moves backward, and the cooled workpiece 10 is placed inside the second compression unit 220. While being inserted, the first compression unit 210 moves backward.

At this time, the pair of elastic members 230 configured between the first compression unit 210 and the second compression unit 220 are relaxed, and the first frame unit 110 and the second frame unit 120 are The first compression unit 210 moving forward and backward is continuously supported.

Therefore, since the mold processing apparatus using the hydraulic cylinder according to the present invention does not require a space for securing the movement of the first cylinder 130 in the first compression unit 210, there is no vulnerability due to the existence of the groove, so that the present invention is robust. There are advantages to being able to keep it.

In addition, in the present invention, it has been described that the first cylinder 130 is coupled to one end of the first compression unit 210, but is not limited thereto.

5 shows a coating unit 300 forming a coating layer on the outer surface of the workpiece 10 .

The coating unit 300 includes a coating liquid storage unit 310, an inlet pipe 320, and an inlet 330, and the coating liquid storage unit 310 is spaced apart from the lower portion of the first compression unit 210 at a predetermined interval. to be formed

A coating liquid of a coating layer to be formed on the outer surface of the workpiece 10 is inserted into the coating liquid storage unit 310, and the coating liquid may be made of polyurethane.

Due to the characteristics of the polymer compound itself, the polyurethane coating layer has strong durability against chemical components such as acid, and thus can maintain corrosion resistance even when exposed to water.

However, the composition of the coating layer is not limited thereto and may include various compositions, and a detailed description thereof will be described later.

An inlet pipe 320 is formed on one side of the coating layer storage unit, and the inlet pipe 320 is inserted into the second compression unit 220 and extends in a vertical direction.

The coating liquid is inserted into the insertion part through the inlet pipe 320, and the coating liquid is formed in a shape surrounding the outer circumferential surface of the workpiece 10.

Thereafter, after drying the workpiece 10 on which the coating liquid is formed for a sufficient time, the workpiece 10 may be detached from the second compression unit 220 or post-processing may be performed thereafter.

Next, the polishing unit 260 for polishing the outer surface of the workpiece 10 will be described in detail with reference to FIGS. 6 and 7 .

A rail part 250 is formed on one side of the second compression unit 220 along the circumference of the workpiece 10, and the rail part 250 is formed to be spaced apart from the workpiece 10 at a predetermined interval. .

The polishing part 260 is composed of a wheel part 261, a supporting part 262, a fitting part 263, and a processing part 264, and a supporting part 262 is formed on the upper part of the wheel part 261.

The supporting portion 262 is in the form of a thin plate, and the fitting portion 263 is formed by extending in the vertical direction on one side and the other side of the lower portion of the supporting portion 262, and the fitting portion 263 is coupled to the center of the wheel portion 261 do.

Therefore, the lower part of the supporting part 262 does not come into contact with the outer circumferential surface of the wheel part 261, so that the rotation of the wheel part 261 is not restricted, and serves to support the processing part 264 to be described later.

A processing unit 264 is formed extending in the vertical direction at an upper portion of the supporting unit 262 , and the processing unit 264 is formed in a roll shape to polish the edge of the workpiece 10 .

Since the processing part 264 is coupled to the upper part of the support part 262 and rotates, if there is no force supporting the processing part 264 from the lower part, a vertical flow may occur when the workpiece 10 is polished, and this flow occurs If so, uniform and smooth polishing may be difficult and the quality of the workpiece 10 may deteriorate.

Therefore, this flow can be prevented by supporting the processing part 264 from the lower part with the configuration of the supporting part 262 .

The processing unit 264 can be replaced with various sizes so as to mold the workpiece 10 of various sizes, and the position of the processing unit 264 can be adjusted and used.

The wheel part 261 rotates along the rail part 250, and the processing part 264 grinds the edge of the workpiece 10 more uniformly and smoothly while rotating while the position is fixed.

Although a pair of polishing parts 260 are located at different positions in FIG. 7 , the number and size of the polishing parts 260 are not limited thereto.

In addition, although not shown in the drawing, since debris and foreign substances generated when grinding the workpiece 10 may interfere with the workpiece 10, a foreign matter suction port may be configured.

With the configuration of the processing unit 264, the processing time can be shortened and the production cost can be reduced by processing only the edges without polishing the workpiece 10 as a whole.

In addition, since the device has a relatively simple configuration and is very easy to use, it can be manufactured at low cost and is convenient to use.

In addition, since both the wheel part 261 and the support part 262 rotate and work is performed, more smooth and uniform polishing can be performed, thereby providing the workpiece 10 with improved gloss efficiency.

The operating process of the mold processing apparatus using the hydraulic cylinder according to the present invention will be described in detail.

First, as the first cylinder 130 moves forward, the first compression unit 210 moves forward along the first frame unit 110 and the second frame unit 120 .

The pair of elastic members 230 are also relaxed, and the workpiece 10 is injected between the first compression part 210 and the second compression part 220 .

When pressing is in progress and when pressing is completed, it can be known through the LED sensor 240, and after the pressing is completed, the workpiece 10 is cooled for a certain period of time.

Next, the coating liquid in the coating liquid storage unit 310 moves through the inlet pipe 320 to form a coating layer on the outer surface of the workpiece 10 .

Thereafter, when the first cylinder 130 moves backward, the first compression unit 210 moves backward accordingly.

Before removing the workpiece 10 from the second compression unit 220, a post-processing process of uniformly polishing the edges of the workpiece 10 through the polishing unit 260 is performed.

As such, since the process of forming a coating layer on the outer circumferential surface of the workpiece 10 and polishing the edges of the workpiece 10 is completed in one process, a separate device is not required, which is convenient and easy.

When the compression unit 200 of the present invention continuously moves forward and backward, one side of the compression unit 200 may be worn.

That is, due to the corrosion phenomenon caused by the action of moisture in the environment in contact with the surface, rusty atmospheric corrosion may occur in the air at room temperature.

Thus, a coating layer is formed on the surface of the compression unit 200 of the present invention through an anti-corrosion coating to prevent corrosion.

The coating layer (not shown) is coated using a coating composition, and the coating layer using the coating composition may exhibit an anti-corrosion effect. Specifically, a coating layer is formed on the surface of the compression unit 200 by the coating layer to prevent the compression unit 200 from being exposed to the outside, and contains a metal having a higher ionization tendency than the compression unit 200. Corrosion of (200) can be prevented.

More specifically, the coating composition of the present invention is a siloxane-based compound represented by Formula 1; organic solvents, metal compounds and amine compounds;

[Formula 1]

Here, n is an integer from 1 to 100.

When the coating layer is formed on the surface of the compression unit 200 using the coating composition of the present invention, the adhesion to the compression unit 200 is excellent, the coating layer is not easily peeled off by external force, and ionization is higher than that of the compression unit 200. As it contains a metal compound with a high tendency, an excellent anti-corrosion effect can be exhibited.

Specifically, since the siloxane-based compound contains a mercapto group as a substituent, it not only exhibits excellent adhesive strength with the compression unit 200, but also increases moldability and stability by maintaining the viscosity of the coating composition at a certain level. .

The metal compound serves as an erosion and corrosion inhibitor that blocks contact with moisture, salt or oxygen. Here, as the metal compound, a metal having a higher ionization tendency than iron may be used to act as an erosion and corrosion inhibitor. That is, metals or alloys such as aluminum (Al), magnesium (Mg), and zinc (Zn) may be used, and zinc (Zn) is mainly used.

The particle size of the metal compound may be 0.1 to 10 μm. If the particle size of the metal compound is 0.1 μm or more, the manufacturing cost of the metal compound can be reduced, and if the particle size of the metal compound is 10 μm or less, the metal particles can be uniformly dispersed.

The organic solvent is selected from the group consisting of methyl ethyl ketone (MEK), toluene, and mixtures thereof, and preferably methyl ethyl ketone may be used, but is not limited to the above examples.

The amine compound may include a modified aliphatic amine or tertiary amines, and specifically, trimethylamine or aniline may be used. The amine compound may be included in the coating composition to prevent cracking or peeling of the coating film. That is, the effect of preventing cracks or peeling of the coating film due to use by increasing the adhesive strength of the coating layer is excellent.

The coating composition may further include a stabilizer as other additives, and the stabilizer may include a UV absorber, an antioxidant, and the like, but is not limited to the above examples and may be used without limitation.

For forming the coating layer, the coating composition is more specifically a siloxane-based compound represented by Formula 1; organic solvents, metal compounds and amine compounds.

The coating composition may include 40 to 60 parts by weight of the siloxane-based compound represented by Formula 1, 20 to 40 parts by weight of a metal compound, and 5 to 15 parts by weight of an amine compound, based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect is expressed to the extent that the water repellency effect due to the interaction of each component is of critical significance, and when it is out of the above range, the synergistic effect is rapidly reduced or almost nonexistent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, when applied to the surface of the compression unit 200, there is a problem that it is not easy to form a coating layer because it flows down, and when it exceeds 1800 cP There is a problem that it is not easy to form a uniform coating layer.

[ manufacturing example 1: Preparation of coating layer]

1. Preparation of coating composition

A coating composition was prepared by mixing methyl ethyl ketone with a siloxane-based compound represented by Formula 1, zinc, and trimethylamine:

[Formula 1]

Here, n is an integer from 1 to 100.

A more specific composition of the coating composition is shown in Table 1 below.

(unit weight parts)2. Preparation of the coating layer

Typically, the experiment was conducted using aluminum, which is a metal material that is easily corroded, instead of the compression unit 200.

After coating the coating composition of DX1 to DX5 on one surface of 10 × 10 cm aluminum, it was cured to form a coating layer.

Experimental example

1. Surface evaluation of appearance

Due to the difference in viscosity of the coating composition, after preparing the coating layer, a sensory evaluation was conducted on whether a uniform surface was formed. Evaluation was conducted on whether or not a uniform coating layer was formed, and the evaluation was conducted according to the following criteria.

×: Formation of non-uniform coating layer

TX1 TX2 TX3 TX4 TX5 sensory evaluation × ○ ○ ○ ×

When forming the coating layer, when the viscosity is less than a certain amount, flow occurs on the surface of the compression unit 200, and it is difficult to form a uniform coating layer after the curing process in many cases. Accordingly, a problem of lowering the production yield may occur. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition and it is impossible to form a uniform coating layer.

2. Measurement of corrosion properties

In order to confirm the corrosion characteristics, a corrosion resistance test was conducted using an aluminum plate without a coating layer as a control and an aluminum plate with a coating layer of TX1 to TX5.

The aluminum plate was immersed in a beaker containing 10% by weight of CuCl2 aqueous solution, and the degree of corrosion was checked over time.

If the generation of hydrogen gas is visually confirmed, it will be said to mean that corrosion occurs, and it was confirmed whether or not corrosion occurred until 24 hours had elapsed.

As a result of the experiment, it was confirmed that hydrogen gas was generated shortly after the aluminum plate, which was a control group, was placed in a beaker, and copper was precipitated in less than 1 hour. In the case of TX1, hydrogen gas was generated after 3 hours, and copper precipitation was confirmed after 6 hours.

In the case of other coating layers, corrosion did not occur even after 24 hours, and it was confirmed that there was an excellent effect in preventing corrosion.
