Description

  The present invention relates to an automatic molding machine that has a mold composed of two general-purpose mold parts and manufactures a foamed molded product.

  A general automatic molding machine includes a mold, and the mold is divided into, for example, two equal parts. The halves of the mold are pressed against each other in the process of manufacturing a molded product.

By the way, in the manufacturing process, the actual mold cannot be directly accessed.
In order to adjust or prepare the mold for the next manufacturing process, the current manufacturing process must be completed. Only after the molded article is removed from the mold, can the mold be accessed directly for adjustment and preparation for the next manufacturing process. Such time-consuming adjustments and preparations are included in the overall time of the manufacturing process, and as a result, the productivity of the automatic molding machine is reduced.

  The present invention has been devised in view of such problems, and an object thereof is to provide a new automatic molding machine capable of improving the productivity of the automatic molding machine.

  In order to achieve the above object, an automatic molding machine according to the present invention is an automatic molding machine used for manufacturing a foamed molded article having at least one molding die, and the molding die includes at least one molding die. The first general-purpose type mold part and one second general-purpose type mold part are combined, and at least two first general-purpose type mold parts are prepared. It is characterized in that it is used in the configuration of a mold.

Thereby, the time concerning a manufacturing process can be shortened.
The at least two first general-purpose type mold parts prepared above are preferably arranged around a common rotation axis, and the rotation axis is preferably supported by an automatic molding machine (molding machine body).
In particular, the first general-purpose type mold part of the automatic molding machine is held by the holding device. To easily install the first general-purpose type mold part in the holding device, the above-mentioned first general-purpose type mold part is attached to the holding device. It is effective to provide an adjustment auxiliary tool for adjusting one general-purpose type mold. The adjustment in this case is, for example, alignment of a first general-purpose type mold.

Here, it is preferable that the adjustment aid has an adjustment surface. This adjustment surface is not parallel to the long axis of the automatic molding machine (the axis that guides the first general-purpose type mold part and the second general-purpose mold part in the direction of separation), but is inclined at an appropriate angle. It shall be.
In this case, the adjustment surface provides centering (positioning between the two mold parts) when the mold is pressed, that is, when the first general-purpose mold part and the second general-purpose mold part are joined. It functions as a guiding centering surface, and the adjustment assisting tool functions as a so-called centering device.

  That is, when joining the first general-purpose mold part and the second general-purpose mold part, one or both of them are moved along the long axis of the automatic molding machine. The mold part and the second general-purpose mold part must be properly aligned (centered) in the direction perpendicular to the long axis and joined. Therefore, an adjustment surface (centering surface) that is not parallel to the long axis is provided as a guide surface on the molding machine body, and this adjustment surface is provided on either the first general-purpose type mold component or the second general-purpose mold component. If a sliding contact surface that slides on the surface is provided and the sliding contact surface is slid on the adjustment surface, the first general-purpose mold part and the second general-purpose mold part are aligned (centering). be able to. For example, in a state where the first general-purpose type mold part is held by the holding device, the first general-purpose type mold part is moved while the sliding contact surface is slid on the adjustment surface, thereby enabling alignment (centering). .

In this case, the adjustment surface and the slidable contact surface are preferably flat surfaces, but may be curved surfaces that can slidably contact each other. When the adjustment surface and the sliding contact surface are flat surfaces, the adjustment surface may be oriented in a direction perpendicular to the major axis, but may be inclined with respect to the major axis.
The automatic molding machine preferably includes a fixing device that securely engages the holding device in order to fix the first general-purpose type mold part in a predetermined position. That is, as described above, when the first general-purpose mold part is aligned with the second general-purpose mold part, the first general-purpose mold part is positioned at the position where the alignment is completed. It is necessary to securely engage and fix the holding device, and thus a fixing device is required.

In the production of a foam-molded article, the foamed part is usually cured in a mold. In order to facilitate access to the mold, the mold often consists of two or more mold parts. These mold parts are connected so as to form a mold having a negative shape with respect to the molded article for the production of the molded article. In the present specification, each part of the mold is referred to as a “mold part”, and a molded product is referred to as a “molded product”.
The mold part can be designed in a desired shape. For example, they can be designed according to the molding shape itself, or may be provided with a holding frame that can fix the molding shape. Further, a supply device for introducing a medium used for molding may be provided.

The mold is composed of a plurality of mold parts, which are usually called variable general-purpose types, and is formed by combining the mold parts of each general-purpose type. For example, the male mold of the mold part is called a first general-purpose type, and the female mold is called a second general-purpose type.
However, this does not limit the shape of each general-purpose type mold part compared to other general-purpose type mold parts. The variable general-purpose mold part may have the same shape, a mirror-symmetric shape, or a different shape.

  The automatic molding machine of the present invention includes at least two first general-purpose type mold parts, and the above-described mold parts are alternately provided in the configuration of the mold. In other words, the mold part having the first general-purpose type used for the structure of the mold can be repeatedly used for the structure of the mold. Similarly, other mold parts of the first general-purpose type used for forming the mold can be repeatedly used for forming the mold.

  A general-purpose mold part is then alternately applied to the mold configuration. This allows access to another mold part used in the next step during the production of the foam molded product. And it becomes possible to prepare for the next manufacturing process during the manufacturing process now in progress. After the current manufacturing process is completed, the mold part in the accessible position constitutes the next mold to be used in the next manufacturing process instead of the mold part of the same general-purpose type. When a new manufacturing process starts, adjustments are made to the first manufacturing process.

Various preparations and adjustments can be considered here. For example, the preparation may be equipped with a blank (semi-processed product), while the adjustment may include removing the finished foamed molded product.
The first general-purpose mold part is arranged around a common rotation axis, and the rotation axis is supported by an automatic molding machine. Here, it is effective to arrange the mold parts symmetrically around the rotation axis. For example, when two first general-purpose type mold parts are arranged, the mold parts are arranged so as to face each other.

The mold part can actually be fixed as required. If the mold part is removable, it can be removed and replaced with another general-purpose type mold part. Thereby, the freedom degree of an automatic molding machine can be raised.
If the first general-purpose type mold part is arranged as described above and the rotary shaft is supported by the automatic molding machine, the first general-purpose type mold part is simply swiveled. It can be replaced. Specifically, the first general-purpose mold part that is not used in any step of the manufacturing process can reach the same position by turning the common rotary shaft.

  Mold parts that are not used in the manufacturing process are alternately moved to the side of the automatic molding machine by different types of movement such as straight insertion. According to the automatic molding machine of the present invention, it is possible to improve ergonomic convenience. This is because the user can be in the same position during actual manufacturing. If the system which performs preparation and / or adjustment automatically is used, the automatic molding machine of this invention is realizable with one system. As a result, the automatic molding machine of the present invention requires a small installation space.

As another particularly effective embodiment, the automatic molding machine includes a shaft holding device. Here, the first general-purpose type mold part is fixed to the shaft holding device. The shaft holding device may basically have any shape. For example, the shaft holding device may include two journals (bearings) facing each other so as to be supported by the frame of the automatic molding machine.
The rotating method for exchanging the mold parts can be used without changing the shape of the automatic molding machine as compared with the conventional automatic molding machine. This allows for retrofitting of a rotating device that replaces each former general-purpose mold part.

  As another effective embodiment, it is preferable that at least the first general-purpose type mold part is disposed at a position in the automatic molding machine that can be easily accessed from the outside. A user, or an automatic preparation and / or adjustment system, can easily access the mold parts, particularly the side surfaces that make up the mold. Specifically, during preparation and / or adjustment, the mold can be accessed directly without any particular obstacles. For example, if there is no frame of the automatic molding machine in the middle, the inside of the mold part can be turned outward by turning.

  It is even more effective to place the mold part around the rotation axis and to place the rotation axis in an area within the automatic molding machine that is easily accessible from the outside. This is because at least one mold part pivots outward about the axis of rotation and stops where the previous mold part was. Thus, the mold is always prepared and / or adjusted in the same position accessible from the outside, in particular in an ergonomic way.

  In another advantageous embodiment, each mold part is preferably provided with a media supply device for process media. Such a medium supply device may be a steam chamber as an example. For example, the steam chamber configuration is used to produce a foam molded article with a foam mold. However, the configuration of the steam chamber depends on the supply mode of water vapor, which is a specific production medium. Here, it is necessary to drain the condensed water after supplying the water vapor.

In order to supply such production media, each mold part is provided with a media supply device for these production media. The medium supply device can be arranged around the rotation axis together with each mold part, or can be fixed to the holding device. In this case, the medium supply device is a part of the swivel component group. That is, each mold part is provided with a dedicated medium supply device.
In another preferred embodiment, the automatic molding machine includes a medium supply device (medium supply device assembled to the molding machine body) for supplying a production medium and a coupling device, and the coupling device supplies the medium for each mold part. The apparatus and the medium supply device of the automatic molding machine can communicate with each other.

After the positioning of the mold parts is completed, the alternately arranged mold part medium supply devices must communicate with the medium supply device of the automatic molding machine. Thereby, a medium can be reliably supplied to the mold part which moves and is located alternately.
The stationary automatic molding machine medium supply device communicates with the medium supply device of the mold part whose arrangement is determined by the coupling device. Here, in practice, any type of coupling device can be used. However, since relatively quick replacement of the mold parts is preferable, separation and connection must be easy and quick. An example of such a coupling device is a movable telescopic tube (movable nested tube).

In practice, the coupling device can be activated as required. In a particularly preferred embodiment, the coupling device may be operable by hydraulic or pneumatic pressure. This has the advantage that the coupling device can be controlled completely automatically. Also, the coupling device is deactivated again after the mold parts are quickly replaced and activated quickly.
Furthermore, as another effective embodiment, the automatic molding machine includes at least one second general-purpose type second mold part, and each first general-purpose type mold part is of the second general-purpose type. The first mold and / or the second mold are configured together with the first mold part and / or the second general-purpose type second mold part.

  By further including at least one second general-purpose type second mold part, the automatic molding machine includes at least two second general-purpose type mold parts. Accordingly, at least two first general-purpose type mold parts are arranged around the common rotation axis, and each of the first general-purpose type mold parts and the second general-purpose type mold parts are combined, and at least Combine two molds.

  However, in practice, the number of first general-purpose type mold parts and the number of second general-purpose mold parts may be different as necessary. Basically, any number of mold parts of the first general-purpose mold type can be arranged around the common rotation axis. Similarly, the number of second general-purpose mold parts is arbitrary, and in particular, the same number as the first general-purpose mold parts may be provided. As a result, the same number of molding dies as each general-purpose mold part can be configured.

One each of the first general-purpose type mold part and the second general-purpose type mold part are provided to form the mold. The first general-purpose type mold parts are alternately combined with the second general-purpose type mold parts.
As a result, first, the first mold is composed of the second general-purpose type first mold part and the first general-purpose type first mold part, and at the same time or after that, the second mold is A general-purpose type second mold part and a first general-purpose type second mold part are included. The numbers of the two mold parts here are merely examples. That is, three or more mold parts may be provided for each general-purpose type.

Next, the first mold is composed of the second general-purpose type first mold part and the first general-purpose type second mold part, and at the same time or after that, the second mold is the second general-purpose type. The second mold part and the first general-purpose type first mold part.
If there are more than two mold parts per general purpose type, the third and fourth molds will participate in the replacement cycle.

  As a special advantage of the automatic molding machine according to the invention, at least one part of one mold becomes part of another mold in the production cycle of the molded product. For example, a molded product processed in a first mold (in other words, partially manufactured) remains connected to one part of the first mold, and in a different manufacturing process, with different mold parts, Further processing. In the step of exchanging at least one mold part, the partially manufactured molded article remains on at least one of the mold parts constituting the first mold.

When the treatment is performed in this manner, a moving operation such as taking out a partially manufactured molded product from the first mold and placing it on the second mold is not necessary. As a result, the cycle time can be shortened, the manufacturing process becomes safe, and the quality of the molded product can be improved.
The first mold and the second mold can be actually created in any order. In particular, it is preferable that the first mold and the second mold are formed simultaneously. Thereby, the cycle time can be significantly shortened. However, it is also possible to create a first mold in the first step and a second mold in the second step.

A plurality of mold parts of the same general-purpose type can be created as necessary. As a preferred embodiment, at least two mold parts of the same general-purpose type are designed with at least various shapes. As a result, after the partially processed molded article is transferred to the second mold, it is further processed at least by mold parts having different shapes.
For example, since the shapes of the mold parts constituting the second mold are different, a second mold having a cavity shape different from that of the first mold can be formed. As a result, the cavity of the second mold can have a larger volume than the cavity of the first mold. Since the volume is further increased by the second foaming, the resulting molded product has two foam pieces (foamed portions).

In practice, the configuration of the foam pieces can be determined as needed. For example, the foam pieces may have the same or similar viscosity, and their density and color may be different.
That is, in practice, it is only necessary that the plurality of mold parts of the same general-purpose type have at least different shapes. A plurality of mold parts of the same general-purpose type may be at least different in shape, but some of the plurality of mold parts of the same general-purpose type have the same or equivalent shape, and at least the rest The shape may be different. Furthermore, the shape of at least the first general-purpose mold part may be different, and the shape of the second general-purpose mold part may be different or the same.

  In practice, it is a matter of whether the first general-purpose type mold part arranged around the common rotation axis or on the second general-purpose type mold part is different.

  According to the automatic molding machine of the present invention, the time required for the manufacturing process can be shortened, and the productivity of the automatic molding machine can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Further, the automatic molding machine fixes the general-purpose type A mold parts 03 and 04 in a predetermined position (that is, a position where the alignment is completed), so that the fixing device is securely engaged with the holding device. (Not shown) is preferably provided.

[Second Embodiment]
FIG. 5 shows an automatic molding machine 30 according to the second embodiment of the present invention, and the automatic molding machine 30 includes a first molding die 31 and a second molding die 32. Further, the automatic molding machine 30 includes a general-purpose type A (first general-purpose type) first molding die component 33 and a general-purpose type A second molding die component 34 arranged around the rotation shaft 35. . The connection between the molding die parts 33 and 34 and the rotary shaft 35 is the same as that described in the first embodiment with reference to FIGS.

The automatic molding machine 30 further includes a general-purpose type B (second general-purpose type) first mold part 36 and a general-purpose type B second mold part 37.
Each of at least one general-purpose type A mold part and general-purpose type B mold part forms a mold 31 and a mold 32. In these mold parts, the first mold parts 36 and 37 of the general-purpose type B are moved toward the mold parts 33 and 34 (laterally) to form two molds 31 and 32, respectively. Have been placed.

The mold parts 33 and 34 can be moved by rotating around the rotation shaft 35. Therefore, the mold part 36 constitutes the first mold 31 with any one of the mold parts 33, 34, while the mold part 37 constitutes the second mold 32 with any one of the mold parts 34, 33. To do.
In the present embodiment, the molds 31 and 32 may be formed at the same time or may be formed at different times. The latter can be realized, for example, by moving the mold parts 36 and 37 in the lateral direction with a time delay.

The mold parts 33 and 34 can actually turn around the rotation axis 35 in an arbitrary direction. The mold parts 33 and 34 may always rotate clockwise around the rotation shaft 35, or may always rotate counterclockwise, and alternately in clockwise and counterclockwise directions. It may rotate.
FIG. 6 is a diagram showing the mold parts 33, 34, 36, and 37 of the automatic molding machine 30 shown in FIG. The mold parts 33 and 34 that rotate together are designed as female molds and each includes a hood 38.

  In contrast, the mold parts 36 and 37 are designed as male molds and have cores 39 and 40, respectively. The first core 39 of the mold part 36 is different in shape from the second core 40 of the mold part 37. As a result, the general-purpose type B mold parts 36 and 37 have different shapes. On the other hand, the hoods 38 of the mold parts 33 and 34 have the same shape in this embodiment.

Actually, the automatic molding machine can include a core having the same shape and a hood having a different shape. Also, if desired, the hood and core can be provided in a rotatable manner during the placement of the parts.
In this embodiment, since the shapes of the cores 39 and 40 are different, the cavity amounts of the molds 31 and 32 are also different. Here, the cavity amount of the mold 31 is smaller than the cavity amount of the mold 32. Therefore, the mold 31 is suitable for manufacturing the first molded product piece 41. Due to the different core 40, the cavity amount of the second mold 32 is larger than that of the mold 31, which is suitable for manufacturing the second molded product piece 42. The molded product pieces 41 and 42 may have different viscosities, densities, and colors, and are firmly connected to each other.

7-14 is a figure for demonstrating the manufacturing process of the molded article which consists of the two molded article pieces 41 and 42. FIG.
FIG. 7 shows the first foam piece 41 already foamed in the hood 38 of the mold part 34. This first molded product piece 41 is already foamed and stable.
As shown in FIG. 8, thereafter, the molds 31 and 32 are simultaneously sealed. Specifically, the mold parts 36 and 37 are sealed by moving laterally toward the mold parts 33 and 34, respectively. The mold 31 is composed of mold parts 33 and 36, and the mold 32 is composed of mold parts 34 and 37.

In FIG. 9, although the shaping | molding die 31 and 32 is sealed, the state which is not completely sealed for convenience is shown. From FIG. 9, it can be seen that the mold cavities have different shapes. Such a difference in shape occurs because the shapes of the cores 39 and 40 are different.
The molds 31 and 32 foam in a sealed state. The right mold 31 is initially empty, but foams to form a first molded product piece 41. The left mold 32 has been filled with the first molded product piece 41 from the beginning, but now foams to form a second molded product piece 42. Since the core 40 has a flatter shape, the mold 32 has a larger cavity amount.

As shown in FIG. 10, the two molds 31, 32 are completely foamed and stabilized, and then opened. The first molded product piece 41 just manufactured remains in the hood 38 of the mold part 33, and the first molded product piece 41 and the second molded product piece 42 manufactured by the left mold 32 are used. The resulting bonded product remains on the core 40 in the mold 32.
Mold parts 36 and 37 move sideways away from mold parts 33 and 34, thereby opening molds 31 and 32 again.

Next, as shown in FIG. 11, the mold parts 33, 34 rotate while leaving the first molded part 41 in the hood 38 of the mold part 33. A bonded product composed of the first molded product piece 41 and the second molded product piece 42 remains on the core 40 of the mold part 37.
As shown in FIG. 12, the mold parts 33, 34 rotate while leaving the first molded product piece 41 in the hood 38 of the mold part 33. The combined product composed of the first forming component part 41 and the second molded product piece 42 remains on the core 40 of the mold component 37.

As shown in FIG. 13, the mold parts 33, 34 rotate while leaving the first molded product piece 41 in the hood hood 38 of the mold part 33. The combined product composed of the first molded product piece 41 and the second molded product piece 42 remains on the core 40 of the mold part 37.
As a result of the rotation, as shown in FIG. 14, the mold part 33 is located where the mold part 34 was present, and conversely, the mold part 34 is located where the mold part 33 was present. The first molded product piece 41 in the hood 38 of the mold part 33 is located at the place where the first molded product piece 41 was located at the beginning of the manufacturing process shown in FIG. It is used for the next step shown. A bonded product composed of the first molded product piece 41 and the second molded product piece 42 on the core 40 of the mold part 37 is removed. In the next series of manufacturing steps, the mold 31 is constituted by the mold parts 34 and 36, and the mold 32 is constituted by the mold parts 33 and 37. Accordingly, the molds 31 and 32 are continuously configured in the manner described above.
In this embodiment as well, it is preferable to include a holding device, an adjustment auxiliary tool (centering device) having an adjustment surface (centering surface), and a fixing device as described in the first embodiment.
As mentioned above, although embodiment concerning this invention was described, each embodiment can be suitably changed and implemented in the range which does not deviate from the meaning of this invention.
