[Prior Art] Conventionally, the first fixed mold and the movable mold are subjected to mold clamping, and the first resin is injected from the first gate, and the first resin portion is molded, and the mold is temporarily opened while being held by the movable mold. The first resin portion slides the second fixed mold as a fixed mold to the movable mold, and the second fixed mold and the movable mold are clamped, and the second resin is ejected from the second gate, and the first resin portion is in the first resin portion. The second resin portion is molded on the side surface, and the mold is opened, and the resin molded article is taken out from the mold (see, for example, Patent Document 1). [Problem to be Solved by the Invention] However, there is a case where an insertion piece is provided between the first resin portion and the second resin portion. For example, the first resin portion is made transparent, and an interposer is provided between the first resin portion and the second resin portion, whereby the pattern layer formed on the interposer can be visually recognized through the first resin portion. The pattern layer is excellent in aesthetics such as a sense of depth. Further, since the first resin portion, the interposer, and the second resin portion are laminated, the strength is increased and the durability is increased to 201026476. However, when the insert piece is provided between the first resin portion and the second resin portion, a part of the insert piece is melted and flows when the resin of the second material is injected, and the gate flows. The gate flow blurs the pattern of the inserted sheet and the like, and reduces the creativity of the resin molded article. When the resin of the second material at a high temperature (250 ° C to 280 ° C) contacts the insert piece, the heat of the resin of the second material is transmitted to the insert piece, and on the other hand, the heat insulating effect of the first resin portion is due to the insert piece. The heat is not transmitted to the second fixed mold, so the insert becomes high temperature. Thus, a part of the insert piece melts and flows as the resin of the second material flows in. In addition, a shape in which the peripheral portion of the resin molded article is bent inward is formed, and a notch is formed in a resin molded article such as a groove in which the peripheral portion is integrally molded with the housing. When the resin molded article is attached to the casing, the cut surface of the cross flow path remaining in the peripheral portion of the resin molded article is not exposed toward the front side, and the appearance is improved. In addition, when the resin molded article is attached to the casing, the resin molded article is not required to be adhered to a resin molded article or the like, for example, and the structure is simplified. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mold for injection molding which can prevent a gate from flowing while injecting a resin of a second material into an insert, and can form a notch and a resin using the mold A method of manufacturing a molded article. [Means for Solving the Problem] 201026476 The mold for injection molding of the present invention can be used for producing a resin molded article having a recessed portion in which an insert piece is embedded, and the first feature is characterized in that: a movable mold; a slide mold is attached thereto The mold is slidably mounted to form the recess; the first fixed mold is configured to form a first cavity between the movable mold and the movable mold by sliding the mold to the first position; In the first gate, the insert piece is placed along the cavity surface of the first fixed mold, and the first resin is emitted into the first cavity to form the first resin portion, and the second fixed mold is used. After the insertion piece 3 is adhered to the first resin portion, the movable mold is moved while holding the first resin, and the sliding mold is slid inward to the second position, and is inserted through the mold clamping. a second cavity is formed between the sheet and the sliding mold; a gate space connected to the second cavity; and a second gate through which the second resin is emitted through the gate space Forming a second resin portion; the insert includes A protruding piece projecting outward from the resin molded article; the gate space being configured to arrange the protruding piece along a front surface of the movable mold when the second cavity is formed. Moreover, the first feature of the method for producing a resin molded article having a recessed portion in which the insert molding die of the present invention is embedded is provided with a step of disposing the first fixed mold and the movable mold. The insert piece is disposed along the cavity surface of the first fixed mold in a state of being opened, so that when the second cavity is formed, the protruding piece protrudes toward the gate space along a surface of the movable mold; In the first cavity forming step, the first fixed mold placed and the movable mold that slides the sliding mold outward to the first position of the 201026476 are mold-locked to form the first cavity; the first resin a portion forming step of forming a first resin from the first cavity to the formed first cavity to form the first resin portion, and a second cavity forming step of adhering the inserted sheet to the formed first resin After that, the first fixed mold and the movable mold are opened, the movable mold is moved, and the second fixed mold is slid inward while the first resin portion is still held. To the second position The movable mold is clamped to form the second cavity, and the second resin portion forming step is performed by the second gate through the gate space in which the protruding piece is disposed, and the second cavity is formed. The second resin portion is formed to form the second resin portion; and the removing step is performed after the insertion sheet is adhered to the formed second resin portion, and the sliding mold is slid outward to the second position, and the second fixing is performed The mold and the movable mold are opened to take out the resin molded article having a notch. According to the invention, when the second resin is injected, the second resin contacts the insert piece through the gate space. The position near the protruding piece of the insertion piece tends to become φ high temperature, and the insertion piece is easily melted. However, in the present invention, by dissipating heat in the vicinity of the protruding piece to the movable mold via the protruding piece, the insertion piece can be prevented from being overheated and the insertion piece can be prevented from being melted. Further, when the molded product is placed on the sliding mold attached to the movable mold, the movable mold and the second fixed mold are mold-locked, and the second resin is injected into the second cavity formed by the mold. , a notch can be formed in the resin molded article. According to a second aspect of the present invention, the gate space includes a recess for accommodating the front end of the protruding piece. According to the present invention, it is possible to prevent the second resin in the gate space from directly hitting the front end of the protruding piece. As a result, it is possible to prevent the insertion piece from floating or rolling up due to the positional deviation of the insertion piece when the second resin is injected. According to a third aspect of the present invention, in the sliding mold and the movable mold, the edge portion of the protruding piece is sandwiched by the sliding mold and the movable mold when the second cavity is formed. According to the present invention, since the edge portion of the protruding piece is held by the sliding mold and the movable mold when the second cavity is formed, the sliding mold forming the notch can have a function of sandwiching the edge portion of the protruding piece. As a result, the configuration of the edge portion of the protruding piece is not required, and the configuration can be simplified. According to a fourth aspect of the present invention, there is provided a fixing means for fixing the protruding piece to a surface of the movable mold when the second resin is emitted. According to the present invention, since the protruding piece is fixed to the surface of the movable mold by the fixing means, it is possible to prevent the insertion piece from being floated or rolled up due to the displacement of the position φ of the insertion piece when the second resin is injected. Therefore, since the contact between the protruding piece and the movable mold can be well maintained, the heat of the insertion piece is surely transmitted to the movable mold through the protruding piece. Thus, the melting of the insert piece can be prevented. According to a fifth aspect of the present invention, there is provided a resin flow path for connecting the second gate and the gate space, and the resin flow path is formed along a side surface of the slide mold. According to the present invention, the communication flow path can be formed by forming the resin flow path so as to be along the side surface of the sliding mold by the sliding mold forming the notch. In addition, 201026476 is easy to clean the cross flow passage because the cross-flow passage that is cooled and solidified in the resin flow path is exposed on the side of the sliding mold. Therefore, the cross flow passage stripping plate is disposed between the fixed mold and the movable mold, and it is not necessary to push out the cross flow passage stripping plate and take out the cross flow passage or the like at the time of mold opening, which simplifies the constitution.

17。這是用以作成在注入第1材料的樹脂時在插入片3不 會產生捲起等之構成。即，在一方的突出片17，如第5 -13- 201026476 圖、第8圖所示’其兩端部分17a被可動模具5及第1固 定模具4夾持固定，如第5圖、第6圖所示’第1固定模 具4只是接觸突出片17的中間部分17b。在另—方的突出 片17,如第5圖及第7圖所示’插入片3的突出片17被可 動模具5及第1固定模具4夾持固定。因而’即使在一方 之突出片17的中間部分17b未被可動模具5及第1固定模 具4夾持，第1材料的樹脂亦不會進入該中間部分17b和 第1固定模具4之間的間隙。 如第6圖所示，於可動模具5和第1固定模具4之間 形成第1連通流路18，其在將可動模具5及第1固定模具 4進行鎖模時，將第1澆口 13和第1空腔2進行連通，並 向第1空腔2注入從第1澆口 13所射出之第1材料的樹脂。 該第1連通流路18具備有：形成於可動模具5的分模 面5a和第1固定模具4的分模面4a之間之直線形的第1 流路部分1 8a、及形成於可動模具5之凸部5b的側面和第 1固定模具4之凹部4b的側面之間之直線形的第2流路部 分18b。第1流路部分18a及第2流路部分18b係曲折狀地 連接。 如屬在第3圖中之Ε-Π箭視平面圖的第9圖、屬第 9圖中之Π — Π箭視側剖面圖的第10圖、屬第9圖中之I 一 I箭視側剖面圖的第11圖、以及屬第8圖中之m — m箭視 平面圖的第12圖所示，在將可動模具5和第2固定模具8 進行鎖模時，構成爲把在插入片3之一方（在第9圖爲右下） -14- 201026476 之突出片17的兩端部分17a以可動模具5及第2固定模具 8夾持固定，同時把在插入片3之另一方（在第9圖爲左下） 之突出片17夾持固定。即’在一方的突出片17’如第9 圖及第12圖所示，插入片3之突出片17的兩端部分17a 被可動模具5及滑動模具10夾持固定，如第9圖及第1〇 圖所示，可動模具5只是接觸突出片17的中間部分17b。 在另一方的突出片17，如第9圖及第11圖所示，插入片3 的突出片17被可動模具5及滑動模具10夾持固定。因而’ 即使在一方之突出片17的中間部分17b未被可動模具5及 滑動模具10夾持，第2材料的樹脂亦不會進入該中間部分 17b和可動模具5之間的間隙。 如第10圖所示，於可動模具5和第2固定模具8之間 形成第2連通流路19，其在將可動模具5和第2固定模具 8進行鎖模時，將第2澆口 15和第2空腔7進行連通，並 向第2空腔7注入從第2澆口 15所射出之第2材料的樹脂。 φ 該第2連通流路19具備有：形成於可動模具5之凸部 5b的側面和滑動模具1 〇之第1樹脂部6側的面1 0a之間之 直線形的第1流路部分19a、形成於可動模具5之分模面 5a和滑動模具1〇之可動模具5側的面l〇b之間並在鎖模方 向看時直角地彎曲的第2流路部分19b以及將第2流路部 分19b和第2澆口 15連通的第3流路部分19c。 參照第13圖、第14圖，具體而言，第3流路部分19c 在滑動模具10位於夾持位置之狀態，利用由內角部20和 -15- 201026476 形’以在鎖模方向延伸。內角部20是在滑動模具位於夾持 位置時’藉由相鄰之滑動模具10的各個側面連接而形成的 部分。另一方面，外角部21是突出構件22之和內角部20 相向之側的外角部分’形成由截面V字形所構成之槽21a， 以在鎖模方向延伸。 因而’利用形成凹口 9的滑動模具10，可形成連通流 路19。而且’在對第2連通流路19注入第2材料的樹脂後， 對複數個滑動模具10向退避位置進行滑動操作時，因爲在 第3流路部分19c內冷卻固化的橫流道（runner)23在槽21 的前端露出，所以可易於除去橫流道23。 如第9圖、第1〇圖所示，在注入第2材料的樹脂時， 在可動模具5和滑動模具1〇之間，形成爲插入片3的一部， 而且形成可收容可和可動模具5抵接之突出片17的中間部 分17b的澆口空間，同時將注入第2材料之樹脂的第2澆 口 15設置於第2材料的樹脂經由澆口空間而注入第2空腔 〇 7的位置。因此，在插入片3所形成之突出片17的中間部 分17b所露出的第1流路部分19a就構成澆口空間。 因而，第2材料的樹脂通過由突出片17和滑動模具10 所夾之澆口空間而被注入。此時，即使高溫之第2材料之 樹脂的熱傳導至突出片17，該熱亦擴散至可動模具5。因 而’插入片3不會發生過熱，而可防止插入片3之基體片 及圖案層的熔化。而且，因爲以可動模具5及滑動模具10 夾持固定插入片3之突出片17的兩端部分17a，所以在注 -16- 201026476 夾持固定插入片3之突出片17的兩端部分17a，所以 入第2材料的樹脂時可防止插入片3的位置偏差。如 良好地保持突出片17和可動模具5的接觸，插入片3 通過突出片17而傳導至可動模具5。因而，可防止插 3之基體片及圖案層的熔化，並防止插入片3的浮起 起等，而可良好地製造雙材料成型品A。 此外，如第10圖所示，在第1流路部分19a和第 路部分19b的連接部R形成有凹部24，以使第1流路 〇 所收容之突出片17的前端17c從第2流路部分19b中 2材料之樹脂的流動退避。凹部24具備有傾斜和可動 5之凸部5b的側面大致相同之一側的傾斜部24a和另 的傾斜部24b，截面形狀形成大致V字形，並構成爲 的傾斜部24a和另一側之傾斜部24b的夾角約90度或 度更大。 因而，可避免第2流路部分19b中之第2材料的 φ 直接碰到突出片17的前端17c。結果，在注入第2材 樹脂時可防止因插入片3的位置偏移而在插入片3發 起或捲起。而且，因爲第1流路部分19a從第2流路 19b傾斜，所以藉由可動模具5之凸部5b之側面的支 而可更加防止在插入片3發生浮起或捲起。 (其他的實施形態） (1)在上述的實施形態，舉例表示在藉由注入第1

second material may also be a resin having a different color. A resin having a different hardness may also be used. In addition, resins with different materials can also be used. For example, the resin of the first material may be a mixture of polycarbon 201026476 acid ester resin, ABS resin, polycarbonate resin and ABS resin, and the resin of the second material may be acrylic acid (PMMA) resin. In particular, when the resin of the first material is made of ABS resin and the resin of the second material is made of acrylic (PMMA) resin, since the moldability of the ABS resin is high, the two-material molding can be favorably performed. Moreover, even if the softening temperature of the ABS resin is lower than the softening temperature of the acrylic (PMMA) resin, the deformation of the ABS resin can be suppressed when the acrylic acid (PMMA) resin is injected due to the presence of the insert sheet 3. As shown in Figs. 1 and 2, the first fixed mold 4 is provided with a first gate 13 which ejects the resin of the first material. The resin of the first material emitted from the first gate 13 is injected into the first cavity 2 formed between the insertion piece 3 on the cavity surface of the recessed portion 4b and one of the movable molds 5. The member 10 disposed on the parting surface 4a of the first fixed mold 4 is a sliding mold 10 for forming an overcut of the two-material molded product A to be described later. The first fixed mold 4 and the second fixed mold 8 are provided with a notch portion 14 for accommodating the slide mold 10. As shown in Fig. 1 and Fig. 2, the second fixed mold 8 is provided with a second gate 15 that emits a resin of the second material. When the second fixed mold 8 and the other movable mold 5 are clamped, the first resin portion 6 and the insert piece 3 provided on the upper surface of the first resin portion 6 are held by the side of the movable mold 5. The resin of the second material is injected into the second cavity 7 formed by the second fixed mold 8, the insert piece 3, and the slide die 10 from the second gate 15. Further, although not described in detail, a transfer sheet feeding device including an extracting portion and a winding portion is attached to the second fixed mold 8. Further, the second fixed mold 8 has a frame-shaped cleat that presses the transfer sheet against the second fixed mold 8 side. -12-201026476 As shown in Figs. 1 to 4 and Fig. 13, in the movable mold 5, projecting members 22 having a substantially rectangular parallelepiped shape projecting toward the mold clamping direction are formed at four corners. Between the protruding members 22 adjacent to the movable mold 5, a plurality of substantially rectangular parallelepiped sliding molds 10 surrounding the peripheral portion of the first resin portion 6 are provided. Fig. 13 shows an example in which four sliding molds 10 are provided, for example. Each of the sliding dies 10 is used to form a notch 9. Each of the sliding molds 10 can be separated from the first resin portion 6 as shown in FIGS. 6 to 8 at the retracted position (first position) away from the first resin portion 6 and as shown in FIGS. 10 to 13 . © and the movable mold 5 holds the nip position (second position) of the edge portion of the protruding piece 17 to perform a sliding operation. As shown in Fig. 10, on the surface 10a on the side of the first resin portion 6 of the slide mold 10, a ridge 16 for forming a groove as a notch 9 in the two-material molded product A is formed. As the sliding operation mechanism of the slide mold 10, for example, a corner pin provided in a state of penetrating the slide mold 10 or a piston cylinder attached to the slide mold 10 or the like can be used. Figure 5 of the 1_1 arrow plan in Figure 3, Figure 6 of the 1_1 arrow side view in Figure 5, and the Π- Π arrow view of the arrow in Figure 5 As shown in Fig. 8 and Fig. 8 which is a side sectional view of the arrowhead of Fig. 5, two rectangular projecting pieces 17 are formed in a state of being protruded from the long side of one side of the insert piece 3. When the movable mold 5 and the first fixed mold 4 are subjected to mold clamping, the movable mold 5 and the first fixed mold 4 are sandwiched and fixed to both ends of the protruding piece 17 of the insert piece 3 (upper right in Fig. 5). The protruding piece 17 of the portion 17a and the other side (upper left in Fig. 5). This is for forming a structure in which the insert piece 3 does not roll up when the resin of the first material is injected. In other words, in one of the protruding pieces 17, as shown in Figs. 5-13-201026476 and Fig. 8, the both end portions 17a are sandwiched and fixed by the movable mold 5 and the first fixed mold 4, as shown in Fig. 5 and Fig. 6. The first fixed mold 4 shown in the figure is only the intermediate portion 17b that contacts the protruding piece 17. In the other protruding piece 17, as shown in Figs. 5 and 7, the protruding piece 17 of the insertion piece 3 is sandwiched and fixed by the movable mold 5 and the first fixed mold 4. Therefore, even if the intermediate portion 17b of one of the protruding pieces 17 is not sandwiched by the movable mold 5 and the first fixed mold 4, the resin of the first material does not enter the gap between the intermediate portion 17b and the first fixed mold 4. . As shown in Fig. 6, a first communication passage 18 is formed between the movable mold 5 and the first fixed mold 4, and the first gate 13 is formed when the movable mold 5 and the first fixed mold 4 are clamped. The first cavity 2 is in communication with the first cavity 2, and the resin of the first material emitted from the first gate 13 is injected into the first cavity 2. The first communication passage 18 is provided with a linear first flow passage portion 18a formed between the split mold surface 5a of the movable mold 5 and the split mold surface 4a of the first fixed mold 4, and a movable mold formed in the movable mold A linear second flow path portion 18b between the side surface of the convex portion 5b of the fifth portion and the side surface of the concave portion 4b of the first fixed mold 4. The first flow path portion 18a and the second flow path portion 18b are connected in a meandering manner. If it is in Figure 3, Figure 9 of the Π-Π arrow view, 属 第 9 Π 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第The eleventh drawing of the cross-sectional view and the t-figure of the m-m arrow in the eighth drawing are shown in Fig. 12, and the movable mold 5 and the second fixed mold 8 are clamped at the insertion sheet 3 when the mold is clamped. One side (the lower right in FIG. 9) -14-201026476 The both end portions 17a of the protruding piece 17 are sandwiched and fixed by the movable mold 5 and the second fixed mold 8, and are placed on the other side of the insertion piece 3 (in the first 9 is the lower left). The protruding piece 17 is clamped and fixed. That is, as shown in Fig. 9 and Fig. 12, the both end portions 17a of the protruding piece 17 of the insertion piece 3 are held by the movable mold 5 and the slide mold 10, as shown in Fig. 9 and As shown in the figure, the movable mold 5 is only in contact with the intermediate portion 17b of the protruding piece 17. In the other protruding piece 17, as shown in Figs. 9 and 11, the protruding piece 17 of the insertion piece 3 is sandwiched and fixed by the movable mold 5 and the sliding mold 10. Therefore, even if the intermediate portion 17b of one of the protruding pieces 17 is not sandwiched by the movable mold 5 and the slide mold 10, the resin of the second material does not enter the gap between the intermediate portion 17b and the movable mold 5. As shown in Fig. 10, a second communication passage 19 is formed between the movable mold 5 and the second fixed mold 8, and the second gate 15 is formed when the movable mold 5 and the second fixed mold 8 are mold-locked. The second cavity 7 is in communication with each other, and the resin of the second material emitted from the second gate 15 is injected into the second cavity 7. φ The second communication channel 19 is provided with a linear first channel portion 19a formed between the side surface of the convex portion 5b of the movable mold 5 and the surface 10a of the first resin portion 6 of the slide mold 1 a second flow path portion 19b formed at a right angle between the parting surface 5a of the movable mold 5 and the surface l〇b of the movable mold 5 on the movable mold 5 side of the movable mold 5, and the second flow, which is formed at right angles when viewed in the mold clamping direction The third flow path portion 19c that communicates with the second portion 15 of the road portion 19b. Referring to Fig. 13 and Fig. 14, specifically, the third flow path portion 19c is extended in the mold clamping direction by the inner corner portion 20 and the -15-201026476 shape in a state where the slide mold 10 is at the nip position. The inner corner portion 20 is a portion which is formed by joining the respective side faces of the adjacent slide molds 10 when the slide mold is at the nip position. On the other hand, the outer corner portion 21 is an outer corner portion of the projecting member 22 and the side opposite to the inner corner portion 20, and a groove 21a formed of a V-shaped cross section is formed to extend in the mold clamping direction. Thus, the communication passage 19 can be formed by the slide mold 10 forming the recess 9. Further, when the resin of the second material is injected into the second communication passage 19, when the plurality of slide molds 10 are slid to the retracted position, the solid runners are cooled and solidified in the third flow path portion 19c. Since the front end of the groove 21 is exposed, the lateral flow path 23 can be easily removed. As shown in FIG. 9 and FIG. 1 , when the resin of the second material is injected, a part of the insertion piece 3 is formed between the movable mold 5 and the slide mold 1 , and a movable mold can be accommodated. 5, the gate space of the intermediate portion 17b of the protruding piece 17 abuts, and the second gate 15 in which the resin of the second material is injected is injected into the second cavity 〇7 through the gate space. position. Therefore, the first flow path portion 19a exposed by the intermediate portion 17b of the protruding piece 17 formed by the insertion piece 3 constitutes a gate space. Therefore, the resin of the second material is injected through the gate space sandwiched by the protruding piece 17 and the sliding die 10. At this time, even if the heat of the resin of the second material at a high temperature is conducted to the protruding piece 17, the heat is diffused to the movable mold 5. Therefore, the insertion sheet 3 does not overheat, and the melting of the base sheet and the pattern layer of the insertion sheet 3 can be prevented. Further, since the both end portions 17a of the protruding pieces 17 of the insertion piece 3 are sandwiched by the movable mold 5 and the slide mold 10, the both end portions 17a of the protruding pieces 17 of the fixed insertion piece 3 are held by the nails -16 - 201026476, Therefore, the positional deviation of the insertion piece 3 can be prevented when entering the resin of the second material. The insertion piece 3 is conducted to the movable mold 5 through the protruding piece 17 as the contact of the protruding piece 17 and the movable mold 5 is well maintained. Therefore, the melting of the base sheet and the pattern layer of the insert 3 can be prevented, and the floating of the insert sheet 3 can be prevented, and the two-material molded article A can be favorably produced. Further, as shown in Fig. 10, a recess 24 is formed in the connecting portion R of the first flow path portion 19a and the first portion 19b so that the front end 17c of the protruding piece 17 accommodated in the first flow path is from the second flow The flow of the resin of the material of 2 in the road portion 19b is retracted. The recessed portion 24 is provided with an inclined portion 24a and a further inclined portion 24b having one side of the side surface of the convex portion 5b which is inclined and movable 5, and has a substantially V-shaped cross-sectional shape, and is formed as an inclined portion 24a and inclined on the other side. The angle of the portion 24b is about 90 degrees or greater. Therefore, it is possible to prevent the φ of the second material in the second flow path portion 19b from directly hitting the front end 17c of the protruding piece 17. As a result, it is possible to prevent the insertion piece 3 from being lifted or rolled up due to the positional deviation of the insertion piece 3 when the second material resin is injected. Further, since the first flow path portion 19a is inclined from the second flow path 19b, it is possible to further prevent the insertion piece 3 from floating or rolling up by the side surface of the convex portion 5b of the movable mold 5. (Other Embodiments) (1) In the above-described embodiment, the insertion sheet 3 is provided on the upper surface of the first resin portion 6 formed by injecting the first resin, and the hot-filled sheet or The side of the second mold portion of the second flow portion is held by the floating portion of the 90 resin material, and the material of the second material is injected into the upper surface of the insert piece 3 of -17-201026476 to produce a two-material molded product A.
