Description

Method for manufacturing glass containers that can be molded into pieces on a parting line

The present invention relates to a mold for manufacturing a glass container capable of forming pieces on a parting line and a method for manufacturing a glass container using the same. In order to increase the aesthetics of the glass container, the present invention relates to a process of molding pieces that protrude to a certain length on the outer surface of the glass container. , In the molded pieces at the parting line, which is the part where the left mold and the right mold come into contact or separate from the entire outer surface of the glass container, scratches occur on these molded pieces during the process of rotating and separating the left mold and the right mold. In order to solve the conventional problem in which pieces could not be molded on the parting line portion of the outer surface of a glass container, a mold for manufacturing a glass container capable of molding pieces uniformly throughout 360 degrees on the outer surface of the glass container and the same were developed. This relates to a glass container manufacturing method.

Cosmetic containers can generally be made of synthetic resin or glass.

The advantage of cosmetic glass containers, which are made of glass rather than synthetic resin materials, is that deterioration of cosmetics can be minimized, and as a result, cosmetics can be stored for a long time without deteriorating.

Furthermore, when it comes to environmental issues related to cosmetic containers, glass materials are more recyclable than synthetic resin materials, so the burden on the natural environment can be minimized when disposed of. In addition, it is known that less environmentally harmful substances are emitted from glass materials during manufacturing than from synthetic resin materials.

Furthermore, cosmetic containers made of glass have better aesthetics than those made of synthetic resin. In other words, glass materials provide aesthetics and visual effects that cannot be felt from synthetic resin materials, so they are preferred as cosmetic containers to add to the luxury of cosmetics.

On the other hand, a disadvantage of cosmetic glass containers, which are made of glass rather than synthetic resin materials, is that, compared to synthetic resin materials that can be easily molded into containers of various shapes, glass materials have limitations in molding the shape due to the characteristics of the glass material. . In other words, in order to manufacture cosmetic containers that can implement the desired function, in the case of synthetic resin materials, the range of molding possible is very wide without limitations in manufacturing, but in the case of glass containers, the moldable range is very wide in manufacturing cosmetic containers that can implement the desired function. The reality is that the scope is very narrow.

In the case of cosmetic glass containers, the aesthetics of the cosmetics container can be increased due to the luxury of the glass material. In addition, interest in the molding of glass containers continues to increase the aesthetics of the glass container through additional decoration or molding. However, as mentioned above, in the case of glass materials, the moldable range is very narrow, so additional molding or decoration cannot be easily performed.

In particular, in order to increase the aesthetics of the glass container, the attempt to uniformly mold a plurality of pieces protruding at a certain length on the outer surface of the glass container is inevitably limited due to the characteristics of the glass material described above according to the prior art.

Referring to FIG. 1 to explain the limitations of the prior art, during the process of molding uniformly protruding pieces at regular intervals at a certain length on the outer surface of a glass container, the left mold and the entire outer surface of the glass container At the parting line, where the right mold is joined or separated, a scratch occurs on the piece as it comes in contact with the piece molded at the parting line during the process of separating the left and right molds at a certain rotation angle, which ultimately causes the piece to break. Since it was impossible to mold the parting line, there was no choice but to mold it plainly.

In other words, the pieces could not be molded uniformly across the entire 360-degree outer surface of the glass container, and the pieces could only be molded in the rest of the glass container except for the plain parting line, so the increase in aesthetics was inevitably limited.

Accordingly, there is an urgent need for a mold for manufacturing a glass container and a method for manufacturing a glass container using the same, which can mold pieces uniformly throughout the entire outer surface of the glass container at 360 degrees.

Therefore, definitions of these terms should be made based on the content throughout this specification.

This will be described with reference to FIGS. 2 to 4.

The mold for manufacturing a glass container according to the present invention includes a left mold 100 and a right mold 200.

The first molded product (F) is a state in which the glass melt falls into a primary mold of a certain shape and is primarily molded to fit the required shape, such as a space for storing cosmetics.

The secondary molding process in which the secondary molding (S) is molded is that air is blown into the inside of the first molding (F) and the heated first molding (F) is formed into the left mold for the second molding. This is a process in which a second molding is formed to match the shape of the inner surfaces of the left mold 100 and the right mold 200 while expanding inside the (100) and right mold (200), or a mold for manufacturing a glass container according to the present invention. With the first molding (F) positioned inside, the left mold 100 and the right mold 200 are in close contact with the outer surface of the first molding (F) to increase the aesthetics of the glass container. It may be a process in which pieces are molded. Of course, the two processes described above can be carried out separately or simultaneously.

This secondary molded product (S) is cooled to finally produce a cosmetic glass container.

Of course, the inner surfaces of the left mold 100 and the right mold 200 can be configured in a shape that corresponds to the shape of the outer surface of the glass container to be finally molded.

The left mold 100 may include a left fixing mold 120, a left separation mold 130, and a left bottom portion 140.

The left fixing mold 120 is a part where the outer surface of the glass container is molded, and of course, the inner surface of the left fixing mold 120 can be configured in a shape corresponding to the shape of the outer surface of the glass container. Therefore, the inner surface of the left fixing mold 120 may be configured in a corresponding shape so that a plurality of pieces are uniformly molded on the outer surface of the glass container.

The left bottom portion 140 may be formed to extend downward from the left fixing mold 120 and be located below the left fixing mold 120 and the left separation mold 130. That is, the left bottom portion 140 may be formed to support the left fixing mold 120 and the left separation mold 130 from below. The portion molded in the left bottom portion 140 of the glass container may be the lower portion of the glass container in which no pieces have been molded.

The left separation mold 130 may be positioned on the side of the left fixing mold 120 while being supported by the left bottom portion 140. Left separation molds 130 may be located on both sides of the left fixing mold 120, respectively. Accordingly, the left mold 100 is divided into three, including a left fixing mold 120 located on top of the left bottom part 140 and two left separation molds 130 located on both sides of the left fixing mold 120. It may be composed of a mold.

This left separation mold 130 may be configured to move forward and backward while positioned above the left bottom portion 140 and with the left fixing mold 120 stationary. That is, the advanced state is a state in which the left mold 100 and the right mold 200 are in close contact with each other, and pieces are molded all over 360 degrees on the outer surface of the glass container, and the backward state is a state in which the pieces are molded and the left mold is molded. This may be in a state before the (100) and the right mold (200) are separated at a certain rotation angle. A detailed explanation will be provided later.

The right mold 200 may include a right fixing mold 220, a right separation mold 230, and a right bottom portion 240.

The right fixing mold 220 is a part where the outer surface of the glass container is molded, and of course, the inner surface of the right fixing mold 220 is configured in a shape corresponding to the shape of the outer surface of the glass container. Accordingly, the inner surface of the right fixing mold 220 may be configured in a corresponding shape so that a plurality of pieces are uniformly molded on the outer surface of the glass container.

The right bottom portion 240 may be formed to extend downward from the right fixing mold 220 and be positioned below the right fixing mold 220 and the right separation mold 230. That is, the right bottom portion 240 may be formed to support the right fixing mold 220 and the right separation mold 230 from below. The part of the glass container that is molded in the right bottom portion 240 may be the lower portion of the glass container in which no pieces have been molded.

The right separation mold 230 may be positioned on the side of the right fixing mold 220 while being supported by the right bottom portion 240. Right separation molds 230 may be located on both sides of the right fixing mold 220, respectively. Accordingly, the right mold 200 is divided into three, including a right fixing mold 220 located on top of the right bottom part 240 and two right separation molds 230 located on both sides of the right fixing mold 220. It may be composed of a mold.

This right separation mold 230 may be configured to move forward and backward while positioned above the right bottom portion 240 and with the right fixing mold 220 stationary. That is, the advanced state is a state in which the left mold 100 and the right mold 200 are in close contact with each other, and pieces are molded all over 360 degrees on the outer surface of the glass container, and the backward state is a state in which the pieces are molded and the left mold is molded. This may be in a state before the (100) and the right mold (200) are separated at a certain rotation angle. A detailed explanation will be provided later.

Accordingly, in the mold for manufacturing a glass container according to the present invention, a piece is formed on the outer surface of the glass container, and the corresponding molds are a left fixed mold 120, two left separate molds 130, a right fixed mold 220, and 2 It can be composed of a total of six molds, with two right side separation molds 230.

The left mold 100 may further include a left driving pin 150 and a first elastic member 160.

A left driving pin penetration hole 132 is formed in the vertical direction in the left separation mold 130, and the left driving pin 150 can move up and down while penetrating through the left driving pin penetration hole 132.

Among the left driving pins 150, the left driving first guide part 152 may be inserted into the upper part of the left driving pin through hole 132, and the left driving pin 150 extends downward from the left driving pin 152. The drive connection part 153 may be located inside the left drive pin penetration hole 132, and the left drive second guide part 154 extending below from the left drive connection part 153 penetrates the left drive pin. It may be inserted into the lower part of the hole 132, and in this state, the left driving pin 150 may be moved up and down.

At this time, a left driving pin bottom through hole 142 is formed in the vertical direction in the left bottom part 140, and the above-described left driving second guide part 154 is inserted into this left driving pin bottom through hole 142. It can be configured to be able to move up and down in the configured state. Even when the left driving pin 150 is moved up as much as possible, a part of the left driving second guide part 154 is inserted into the lower part of the left driving pin through hole 132, and the remaining part is still inserted into the left driving pin bottom through hole ( 142).

Accordingly, the left driving pin through-hole 132 and the left driving pin bottom through-hole 142 may be connected in a vertical direction.

The first elastic member 160 is located in the lower part of the left driving pin bottom through hole 142, and accordingly, the lower surface of the left driving pin bottom through hole 142 in a closed state by a certain means is the first elastic member 160. It may be in close contact with the elastic member 160.

Therefore, in a state in which the left driving pin 150 is moved upward by the elastic force of the first elastic member 160, the blower head is in close contact with the upper surfaces of the left mold 100 and the right mold 200, and the left driving pin 150 ), when an external force is applied, the left driving pin 150 may be configured to move downward due to this external force.

When the blower head is separated from the upper surfaces of the left mold 100 and the right mold 200 again, the left driving pin 150 may be moved upward due to the elastic force of the first elastic member 160. In this way, the left driving pin 150 can be moved up and down while it is inserted into the left driving pin through-hole 132 and the left driving pin bottom through-hole 142.

Among the left driving pins 150, the left driving second guide part 154 is inserted into the fixed left driving pin bottom through-hole 142, so that the left driving pin 150 can only move up and down. It can be configured.

The left mold 100 may include a left guide cover 101 located on the upper surface of the left fixing mold 120 and the left separation mold 130. In this left guide cover 101, a hole is formed through which the left driving first guide part 152 passes, so that the left driving pin 150 is penetrated through this fixed left guide cover 101, similarly. The left driving pin 150 can be configured to only move up and down by the left guide cover 101.

However, since the left separation mold 130 is blocked from upward movement by the left guide cover 101, the left separation mold 130 only moves forward and backward according to the up and down movement of the left driving pin 150. It can be configured to make it possible. That is, in a state in which the left separation mold 130 is not moved up and down, the left driving pin 150 moves upward or downward, and the left driving pin through hole 132 of the left separation mold 130 is opened. Depending on where the left driving connection part 153 is located on the inside, the left separation mold 130 is only positioned in an advanced or backward state.

The driving relationship between the left driving connection part 153 and the left separation mold 130 according to the vertical movement of the left driving pin 150 will be described later.

The right mold 200 may further include a right driving pin 250 and a second elastic member 260.

A right driving pin through hole 232 is formed in the vertical direction in the right separation mold 230, and the right driving pin 250 can move up and down while penetrating through the right driving pin through hole 232.

Among the right driving pins 250, the right driving first guide part 252 may be inserted into the upper part of the right driving pin through hole 232, and the right side extending downward from the right driving pin first guide part 252. The drive connection part 253 may be located inside the right drive pin penetration hole 232, and the right drive second guide part 254 extending downward from the right drive connection part 253 penetrates the right drive pin. It may be inserted into the lower part of the hole 232, and in this state, the right driving pin 250 may be moved up and down.

At this time, a right driving pin bottom through hole 242 is formed in the vertical direction in the right bottom part 240, and the above-described right driving second guide part 254 is inserted into this right driving pin bottom through hole 242. It can be configured to be able to move up and down in the configured state. Even when the right driving pin 250 is moved up as much as possible, a part of the right driving second guide part 254 is inserted into the lower part of the right driving pin through hole 232, and the remaining part is still inserted into the right driving pin bottom through hole ( 242).

Accordingly, the right driving pin through-hole 232 and the right driving pin bottom through-hole 242 may be connected in a vertical direction.

A second elastic member 260 is located in the lower part of the right driving pin bottom through hole 242, and accordingly, the lower surface of the right driving pin bottom through hole 242 in a closed state by a certain means is this second elastic member 260. It may be in close contact with the elastic member 260.

Therefore, in a state in which the right driving pin 250 is moved upward by the elastic force of the second elastic member 260, the blower head is in close contact with the upper surfaces of the left mold 100 and the right mold 200, and the right driving pin 250 ), when an external force is applied, the right driving pin 250 may be configured to move downward due to this external force.

When the blower head is separated from the upper surfaces of the left mold 100 and the right mold 200, the right driving pin 250 may be moved upward due to the elastic force of the second elastic member 260. In this way, vertical movement is possible while the right driving pin 250 is inserted into the right driving pin through-hole 232 and the right driving pin bottom through-hole 242.

Among the right driving pins 250, the right driving second guide part 254 is inserted into the fixed right driving pin bottom through-hole 242, so that the right driving pin 250 can only move up and down. It can be configured.

The right mold 200 may include a right guide cover 201 located on the upper surface of the right fixing mold 120 and the right separation mold 230. In this right guide cover 201, a hole is formed through which the right driving first guide part 252 passes, so that the right driving pin 250 is penetrated through this fixed right guide cover 201, similarly. The right driving pin 250 can be configured to only move up and down by the right guide cover 201.

However, since the right separation mold 230 is blocked from moving upward by the right guide cover 201, the right separation mold 230 can only move forward and backward according to the up and down movement of the right driving pin 250. It can be configured. That is, in a state in which the right separation mold 230 is not moved up and down, the right driving pin 250 moves upward or downward, causing the right driving pin through hole 232 of the right separation mold 230. Depending on where the right driving connection part 253 is located on the inside, the right separation mold 230 is only positioned in an advanced or backward state.

The driving relationship between the right driving connection part 253 and the right separating mold 230 according to the vertical movement of the right driving pin 250 will be described later.

The configuration of the left driving pin 150 will be described.

As described above, the left driving pin 150 is located below the left driving first guide part 152 and the left driving first guide part 152 at a regular interval in the vertical direction ( 154) and a left driving connection part 153 connecting the left driving first guide part 152 and the left driving second guide part 154.

More specifically, the upper surface of the left driving connection part 153 is connected to a part of the lower surface of the left driving first guide part 152, and the part of the lower surface of the left driving first guide part 152 is biased toward the front. can be connected to The bottom surface of the left driving connection part 153 is connected to a portion of the upper surface of the second left driving guide part 154, and may be connected to a portion of the upper surface of the second left driving guide part 154 that is biased toward the rear.

That is, the left driving first guide part 152 and the left driving second guide part 154 may be located on the same vertical line, but the left driving connection part 153 may be inclined at a certain angle from this vertical line. It may be configured to connect the left driving first guide part 152 and the left driving second guide part 154.

The left drive connection portion 153 may have any shape, but is preferably formed in a polygonal shape. Accordingly, of course, a portion of the left driving pin through-hole 132 formed inside the left separation mold 130 may be configured in a shape corresponding to the polygonal shape of the left driving connection portion 153.

Accordingly, as the left driving connection part 153 moves in the downward direction, the position inside the left driving pin through-hole 132 corresponds to the upper part of the left driving connecting part 153, and the position of the left driving connection part 153 The upper part is positioned toward the front and toward the inner side of the left side separation mold 130 (i.e. toward the center of the mold). The left side separation mold 130 is located above the left driving connection portion 153. Of course, it may be in a forward-moved state ((a) in Figure 5).

On the other hand, as the left driving connection part 153 moves upward, the position inside the left driving pin through hole 132 corresponds to the lower part of the left driving connecting part 153, and the lower part of the left driving connecting part 153 The portion is located biased toward the rear and is biased toward the outside of the left separation mold 130 (i.e., the direction away from the center of the mold). The left separation mold 130 is located at the lower part of the left driving connection portion 153. ) may naturally be moved backwards (Figure 5(b)).

That is, according to the vertical movement of the left driving pin (150). The left separation mold 130 may be moved forward or backward in a direction toward the inner center formed when the left mold 100 and the right mold 200 are combined.

The description of the right driving pin 250 refers to the left driving first guide part 152, the left driving connecting part 153, and the left driving second guide part 154, respectively, in the description of the left driving pin 150 described above. It is replaced with a description of the state in which the right driving first guide part 252, the right driving connecting part 253, and the right driving second guide part 254 are changed.

Furthermore, the description of the relationship between the components of the right driving pin 250 and the right separation mold 230 refers to the description of the relationship between the components of the left driving pin 150 and the left separation mold 130 described above. The driving pin 150 and the left separation mold 130 are replaced with the description of the state in which the right driving pin 250 and the right separation mold 230 are changed, respectively.

Accordingly, according to the vertical movement of the right driving pin (250). The right separation mold 230 may be moved forward or backward in a direction toward the inner center formed when the left mold 100 and the right mold 200 are combined.

Referring to Figure 6, the process of manufacturing an organic container using a mold for manufacturing a glass container according to the present invention will be described.

Figure 6 (c) is a view showing the primary molding (F) in a state in which the glass melt is dropped into the primary molding mold of a certain shape and is primarily molded to fit the required shape, such as a space for storing cosmetics. am. The outer surface of the first molding (F) is in a state where the pieces have not yet been molded.

Figure 6 (d) shows the first molding (F) located inside the hollow formed when the left mold 100 and the right mold 200 are in close contact with each other, and the blower head is connected to the left mold 100. This is a diagram showing a state seated on the upper surface of the right mold 200.

Of course, the inner surface of the left mold 100 and the inner surface of the right mold 200 can be configured in a shape that corresponds to the shape of the pieces to be molded on the outer surface of the glass container. Furthermore, since the left driving pin 150 and the right driving pin 250 are moved downward due to the seating of the blower head, the left separation mold is formed on the upper part of the left driving connection part 153 and the right driving connection part 253. The inside of the 130 and the right separation mold 230 is positioned, and as a result, the left separation mold 130 and the right separation mold 230 are advanced toward the inner center of the hollow. In this state, the inner surfaces of the left fixing mold 120, the two left separating molds 130, the right fixing mold 220, and the two right separating molds 230 are continuous and conform to the shape of the outer surface of the glass container. They are arranged to correspond.

In this case, the left separation mold 130 and the right separation mold 230 are moved forward in a backward state, so that the left separation mold 130 and the right separation mold 230 are directed toward the center of the inside of the hollow of the mold. Only by moving forward can the inner surfaces of the six molds be continuously connected.

In the present invention, the upper surface of the left separation mold 130 and the right separation mold 230 are guided so that the left separation mold 130 and the right separation mold 230 are guided to move forward in the direction of the center of the inside of the hollow of the mold. A left separation mold guide groove 134 and a right separation mold guide groove 234 may be formed on the upper surface, and a left separation mold guide groove 134 may be formed on the lower surface of the left guide cover 101 at a position corresponding to the left separation mold guide groove 134. A left separable mold guide protrusion 105 may be formed, and a right separable mold guide protrusion 205 may be formed on the lower surface of the right guide cover 201 at a position corresponding to the right separable mold guide groove 234. .

Accordingly, with the left separation mold guide protrusion 105 and the right separation mold guide protrusion 205 inserted into the left separation mold guide groove 134 and the right separation mold guide groove 234, respectively, the left separation mold 130 ) and the right separation mold 230 moves forward or backward, so the forward or backward movement of the left separation mold 130 and the right separation mold 230 can be guided.

Furthermore, the left separation mold 130 located on both sides of the left fixing mold 120 and the right separation mold 230 located on both sides of the right fixing mold 220 can be positioned in close contact with each other. . That is, when the left mold 100 and the right mold 200 are in close contact, the left separation mold 130 and the right separation mold 230 must be moved forward or backward at the same time while in close contact with each other.

Therefore, a mounting groove 135 is formed on the side of the left separation mold 130 so that the left separation mold 130 and the right separation mold 230 move simultaneously while the left mold 100 and the right mold 200 are in close contact. may be formed, and a mounting protrusion 235 may be formed on the side of the right separating mold 230 corresponding to the mounting groove 135 of the left separating mold 130.

With the left mold 100 and the right mold 200 in close contact and the mounting protrusion 235 mounted in the mounting groove 135, the left separation mold 130 and the right separation mold 230 move forward and backward. As a result, the left separation mold 130 and the right separation mold 230 can be moved forward and backward at the same time.

Figure 6(e) shows that the left driving pin 150 and the right driving pin 250 are connected to the first elastic member 160 and As it is moved upward due to the elastic force of the second elastic member 260, the inside of the left separation mold 130 and the right separation mold 230 are located below the left driving connection part 153 and the right driving connection part 253. Positioned, the left separation mold 130 and the right separation mold 230 are in a backward state. In this state, the left fixing mold 120 and the right fixing mold 220 are in a relatively advanced state, and the two left separation molds 130 and the two right separation molds 230 are in a relatively backward state. The inner surfaces of the left fixing mold 120 and the right fixing mold 220 and the inner surfaces of the two left separating molds 130 and the two right separating molds 230 are not continuous.

Figure 6(f) is a diagram showing a state in which the left mold 100 and the right mold 200 are separated, with pieces molded all over 360 degrees of the outer surface of the glass container. Figure 6 (f) shows the forward and backward movement of the left separation mold 130 and the right separation mold 230 according to the positions of the left driving pin 150 and the right driving pin 250, the left guide cover ( 101) and the right guide cover 201 are shown with them removed.

In the prior art, during the process of separating the left mold and the right mold, the protruding portion formed on the mold part of the left mold corresponding to the parting line of the glass container was already formed on the parting line of the glass container during the process of rotating and separating. As the pieces were separated while rotating while in contact with the pieces, there was a problem in that scratches, etc. occurred on the pieces as they were rotated in a state of contact with pieces that were already molded on the parting line and protruded at a certain length. The same goes for the right mold.

However, in the present invention, in a state in which a piece is molded on the outer surface of a glass container, before the left mold 100 and the right mold 200 are rotated and separated, the left separation mold 130 and the right separation mold corresponding to the parting line are separated. Since the mold 230 is rotated and separated while being moved backwards, the mold 230 can be rotated and separated without contacting the piece already molded at the parting line. Accordingly, problems such as scratches on the pieces formed on the parting line do not occur, and ultimately the pieces can be molded uniformly throughout 360 degrees of the outer surface of the glass container, thereby increasing the aesthetics of the glass container.

Figure 6 (d) shows that after the first molding (F) is located inside the hollow formed while the left mold 100 and the right mold 200 are in close contact, the left fixing mold 120 and the right fixing mold 120 This is a diagram showing a state in which the left separation mold 130 and the right separation mold 230 are moved forward in the inner direction of the hollow and are in close contact with the outer surface of the first molding (F) while the mold 230 is stopped. . Accordingly, as the inner surface of the left separation mold 130 and the inner surface of the right separation mold 230 come into close contact with the outer surface corresponding to the parting line of the first molding (F), the first molding (F) The piece is molded on the parting line to form the second molded product (S).

Figure 6 (e) shows that after the secondary molding (S) is formed, the left fixing mold 120 and the right fixing mold 230 are stopped, and the left separation mold 130 and the right separation mold 230 are shown. This is a diagram showing a state in which the object is moved backward in the direction opposite to the inner direction of the hollow and separated from the outer surface of the secondary molding (S).

6(f) shows the left mold 100 in a state where the left separation mold 130 and the right separation mold 230 are already separated at a certain distance from the outer surface of the secondary molding (S). This is a diagram showing a state in which the right mold 200 is rotated at a certain angle and separated from the secondary molding (S).
