Detailed Description
The embodiments are described in detail below with reference to the drawings. The following embodiments do not limit the invention in the claims, and the combination of features described in the embodiments is not necessarily an essential feature of the invention. Two or more of the plurality of features described in the embodiments may be arbitrarily combined. The same or similar structures are denoted by the same reference numerals, and repetitive description thereof will be omitted. In each of the drawings, the vertical, horizontal, and vertical directions with respect to the paper surface are referred to as the vertical, horizontal, and vertical directions of the member (or the accessory) of the present embodiment, and are used in the description of the present specification. In the embodiments described below, the resin material is assumed as the molding material, but the present invention is not limited to this, and other materials (thermoplastic resins such as polystyrene, polyethylene, ABS, thermosetting resins, metals, etc.) may be applied.
Fig. 1 shows a cross-sectional view of a molding apparatus 10 according to an embodiment of the invention. As shown in fig. 1, the molding apparatus 10 of the present embodiment includes: a moving die body 102 attached to a moving side of a molding material injection device, not shown, that injects a molding material; and a fixed die body 103 mounted on a fixed side of the molding material injection device. Runner grooves into which molding material flows are formed in the movable mold body 102 and the fixed mold body 103, respectively.
The movable die body 102 has a male die mounting plate 107 on which the male die 106 is mounted, a fixing table 108 on which the male die mounting plate 107 is fixed, a movable side mounting plate 109 mounted on the molding material injection device, and a spacer 110 provided between the fixing table 108 and the movable side mounting plate 109. The male die 106 and the male die mounting plate 107 may be integrally formed, or may be separately formed as a single body. A hollow chamber 111 is formed in the fixed stage 108, and a movable push-out plate 112 is provided in the hollow chamber 111. The push-out plate 112 is fixed to a pressing shaft 116, and the pressing shaft 116 is provided in openings 114 and 115 formed in the fixed stage 108 and the movable-side mounting plate 109. The ejector plate 112 is provided with an ejector pin 113 penetrating the male die attachment plate 107 and the male die 106. Here, the ejector plate 112 is moved so that the tip end of the ejector pin 113 protrudes into the runner slot.
The fixed die body 103 has a fixed mounting plate 117 mounted to the molding material injection device, a female die mounting plate 119 to which the female die 118 is mounted, and a spacer 120 provided between the fixed mounting plate 117 and the female die mounting plate 119. The female die 118 and the female die attachment plate 119 may be integrally formed, or may be separately formed as a single body. A main runner cover 104 is attached to the stationary mold body 103, and the main runner cover 104 is used to inject molten molding material from a molding injection device. The main runner sleeve 104 extends to the female mold 118 through the fixed attachment plate 117, and a main runner 105 as a supply channel for molten resin is formed inside the main runner sleeve 104. The main runner 105 communicates with a runner groove formed in the female die 118 and the male die 106, and a molding material flows into a molding space (cavity) formed in the female die 118 and the male die 106 through the runner groove.
The male die 106 and the female die 118 are each formed with a concave-convex shape, and the concave-convex shapes are joined to form a cavity defining the outer shape of the molded article. When the molding material flows into the cavity and is cooled and solidified, a molded article corresponding to the shape of the cavity is formed. Hereinafter, the male die 106 and the female die 118 are also collectively referred to as a molding die.
The molding die is configured to include a plurality of die members configured to be capable of being inserted into and removed from the molding die. The mold member is disposed on a contact surface between the male mold 106 and the female mold 118, and is inserted into a cavity formed in the molding die from a side surface of the molding die orthogonal to the contact surface. This can prevent the molding material from flowing into the cavity defined by the male die 106 and the female die 118, and can form a hollow or tubular molded article.
In the present embodiment, by inserting the mold members from a plurality of directions with respect to the cavity for molding one molded article, a molded article of a shape which cannot be formed by a single mold member can be molded. In the present embodiment, the above-described mold member is referred to as a sliding mold member.
In the molding apparatus 10 shown in fig. 1, after molding material is flowed into a runner groove to form a cavity for each part, the movable mold body 102 is separated from the fixed mold body 103, then, the slide mold members are separated from the movable mold body 102, and after all the slide mold members are separated, the push-down shaft 116 is pressed to move the push-out plate 112, and if so, the push-out pins 113 provided in the push-out plate 112 push out the molded article attached to the male mold 106 constituting the movable mold body 102, and the molded article can be taken out.
Fig. 1 is a diagram showing an example of the structure of the molding apparatus 10, and the structure of the molding apparatus 10 is not limited to the structure shown in fig. 1, but can be variously modified.
Next, a molding method of a molded product according to the present embodiment will be described with reference to fig. 2. First, in S201, the male mold 106 is placed on the moving mold body 102 of the molding apparatus 10, then, in S202, the 1 st slide mold member is placed, and in S203, the 2 nd slide mold member is placed. Here, the 1 st slide mold member and the 2 nd slide mold member are paired mold members, and a hollow molded article can be molded by a combination of the two slide mold members and the male mold 106 and the female mold 118. In addition, a plurality of such pairs of sliding mold parts can be included for male mold 106 and female mold 118. In addition, three or more sliding mold members may be combined with one molded article.
The 1 st slide die member and the 2 nd slide die member can be attached to a predetermined slide mechanism of the moving die body 102 of the molding apparatus 10. By this slide mechanism, each slide mold is slid (slid) in a predetermined direction, and is inserted into a cavity formed by a male mold and a female mold before molding material is charged, and is pulled out after the molding material is solidified.
Next, in S204, the movable mold body 102 including the slide mold member is moved toward the fixed mold body 103 side, and is combined with the fixed mold body 103. Next, in S205, the molding material is injected from the main runner 105, and the molding material flows into the cavity formed by the male mold 106, the female mold 118, and the slide mold member. Then, after the molding material is cooled and solidified, the movable mold body 102 is separated from the fixed mold body 103. At this time, the molded article is attached to the side of the moving die body 102.
Next, in S207, the 1 st slide die member is separated from the inside of the molded article by the slide mechanism of the molding apparatus 10, and in S208, the 2 nd slide die member is separated from the inside of the molded article by the slide mechanism of the molding apparatus 10. If the molded article is to be taken out before the slide mold members are separated, the molded article may be damaged, and therefore, the molded article is taken out after all the slide mold members are separated. Next, in S209, the ejector plate 112 is moved so that the tip end of the ejector pin 113 protrudes into the runner slot, and the molded product is taken out.
Next, referring to fig. 3, an example of the structure of a molded article according to the present embodiment is shown. Fig. 3 (a) is a diagram showing an example of the appearance of the molded article 300 as viewed from the opening 301 of the molded article 300 toward the front. Fig. 3 (B) is a diagram showing an example of the appearance of the molded article 300 as viewed from the opening 301 of the molded article 300 toward the left. Fig. 3 (C) is a diagram showing an example of the appearance of the molded article 300 as viewed from the bottom surface side of the molded article 300.
The molded article 300 shown in fig. 3 is a hollow mold member having two openings, namely, a front opening 301 and a bottom opening 303, and the openings are connected. The molded article 300 is configured to be able to be coupled to other molded articles via the openings 301 and 303, and thus, can constitute a part of the finished toy body. The openings 301 and 303 are formed on different surfaces of the molded article 300, but the arrangement of the openings is not limited to the configuration shown in fig. 3.
A mold member having a shape like the molded article 300 can be produced by combining two molded articles, but in the present embodiment, the mold member is molded as a single piece. Thus, the hollow portion connected from the opening 301 to the opening 303 needs to be formed by removing the molding material from the cavity by using the sliding mold member. At this time, if the hollow portion is to be formed by only a single slide mold member, it is necessary to open the portion shown by the hatched area 304 in fig. 3. However, if the opening 301 is enlarged, the internal structure can be visually confirmed from the outside correspondingly, which is not preferable.
Then, in the present embodiment, the hollow portion can be formed while maintaining the opening 301 as small as possible by a combination of the slide mold member (1 st slide mold member) for inserting and forming the hollow portion from the opening 303 side and the slide mold member (2 nd slide mold member) for forming the edge portion 302 of the opening 301.
Fig. 4 is a cross-sectional view showing an example of the relationship between the sliding mold member and the male mold 106. In fig. 4, (a) of fig. 4 shows a case where only a single sliding mold member 401 is used, and (B) of fig. 4 shows a case where sliding mold members 411 and 412 are used.
In fig. 4 (a), a sliding mold member 401 is inserted from the bottom surface side of the male mold 106 and protrudes on the top side. This enables the hollow molded article 400 to be molded. However, in this case, the opening on the top side of the molded article 400 must be in a form that does not cause any obstacle to the removal when the slide mold member 401 is removed.
In contrast, in fig. 4 (B), the slide mold member 411 is inserted from the bottom surface side of the male mold 106, and the slide mold member 412 is inserted from the top side obliquely upward of the male mold 106. This enables the hollow molded article 410 to be molded. In this way, the slide mold member 411 and the slide mold member 412 are inserted into and removed from different sides of the molding mold. At this time, the top-side opening of the molded article 410 is defined in its form by the combination of the slide mold member 411 and the slide mold member 412. That is, in the opening, the 1 st portion which does not become an obstacle when the slide mold member 411 is pulled out can be formed by the slide mold member 411, and the remaining 2 nd portion can be formed within a range which does not become an obstacle when the slide mold member 412 is pulled out. Alternatively, the sliding mold member 412 may be used to form all of the openings (particularly, the edge portions). Thus, a shape that cannot be formed by a single slide mold member can be realized by a plurality of slide mold members having different pull-out directions.
Next, the structure of the hollow portion of the molded article 300 will be described with reference to fig. 5. Fig. 5 (a) shows an example of a cross-sectional structure of the molded article 300 when the molded article 300 is viewed from one direction in the A-A cross section of the molded article 300 in fig. 3 (a). Fig. 5 (B) shows an example of a cross-sectional structure of the molded article 300 in the case where the molded article 300 is viewed from the opposite direction to the one direction in the A-A cross section of the molded article 300 in fig. 3 (a).
At this time, the range corresponding to the inner wall portion 501 continuous from the opening 303 on the lower side of the molded article 300 can be molded by the 1 st slide mold member corresponding to the slide mold member 411 of fig. 4. In addition, a range corresponding to the portion 502 of the edge portion 302 of the opening 301 shown as the molded article 300 in fig. 3 can be molded by the 2 nd slide mold member corresponding to the slide mold member 412 in fig. 4. Thus, a molded article having a shape which cannot be molded by a single slide mold member can be molded by the combination of the slide mold members.
Next, an example of a runner structure for securing a path for inserting and extracting a sliding mold member will be described with reference to fig. 6. Fig. 6 (a) is a diagram showing an example of a state in which the sliding mold member is inserted, and fig. 6 (B) is a diagram showing an example of a state in which the sliding mold member is extracted. In fig. 6, the male die 106 and the female die 118 are omitted.
As shown in fig. 6 (a), the sliding die member 602 is inserted into the molded article 601. At this time, the molded article 601 is connected to the runner fitting 603. The runner fitting 603A existing in the direction of insertion and extraction of the sliding mold member in the runner is shaped to bypass (or straddle) the sliding mold member 602. As a result, as shown in fig. 6 (B), the insertion/extraction path of the slide mold member 602 is ensured, and therefore, the runner fitting 603 does not become an obstacle at the time of insertion/extraction. If the runner fitting 603 is located at a position overlapping the sliding mold member 602, it is impossible to inject a molding material into the runner groove or the runner has to be broken to pull out the sliding mold member 602. In the present embodiment, a runner groove is formed in at least one of the male mold 106 and the female mold 118 so as to bypass the sliding mold member 602 or the insertion/extraction path of the sliding mold member 602.
In fig. 6, a case where the runner fitting 603 is provided only in one direction is shown, but in a case where two or more slide mold members as described above are used, runners in the insertion and extraction directions of the respective slide mold members are arranged so as to bypass the insertion and extraction directions of the slide mold members to ensure insertion and extraction paths of the slide mold members.
According to the molding die according to the above embodiment, a molded article having a shape that cannot be molded by a single slide die member can be molded by combining two or more slide die members.
