面，欲充分地抑制焊接部附近之樹脂的收縮時，粗面的面 積變成過大（即，需要***構件之與樹脂構件重疊之面的大 部分形成粗面°)°粗面的面積變成過大時’易導致導電性 等之物性的變化、創意性降低。又，在形成粗面後，對包 含粗面之***構件的表面施加電銀處理的情況，電鐘層形 成於粗面的凹凸上，而有樹脂構件與***構件之密接性不' 會變強的傾向。 如第5圖（c)所示，在***構件未形成粗面110的情 況，無法使樹脂構件之收縮、膨腺量變小，而無法抑制因 樹脂構件收縮、膨脹而作用於樹脂構件12的負擔。 在本實施形態，粗面係利用雷射加工形成於***構件 二1的表面。若是利用雷射處理形成粗面的方法，因為局部 處理亦容易’所以可易於將粗面形成於所要之範圍。 以上’說明了第i實施形態的***件成形體，但是如 第6圖（a)所示’亦可是焊接部與應力集中部—致的插人件

Therefore, it is required to prevent the cracking of the thermoplastic resin member even when it is disposed in an environment having a large temperature change.

The resin composition described in Patent Document 2 is excellent as a resin material having high thermal shock resistance to a heat-resistant resin member. However, in recent years, the demand for thinner thermoplastic resin members has also become smaller, and the shape of the parts has become complicated, and the formation of the welded portion of the thermoplastic tree member has not been avoided, and it is required to further improve the Thermal shock resistance.

The present invention will be described by taking the case of the present invention as an example after explaining the insert and the hot plastic resin member. Connected state).

(4th embodiment <insert member> 201236846 The octagonal member can be used from the U-type...former-r-.p. The material constituting the insert member can also be any of the gold/organic materials. .,,, machine materials, Shao, copper, gold, silver, yellow steel, etc., such as gold, stainless steel, stainless steel, stainless steel, metal, thermal conductive ceramics, etc. Examples of the film which can be used as the intercalation material as a metal include a film formed by electroplating, a plating treatment (wet type, old type, electric ore treatment, etc.). Further, a member is inserted: The monomer of the inorganic material or the like may also be referred to as a composite having a complex:: grease 4. The determination of the material of the insert member by the A tree t is, for example, a thermal expansion coefficient of the resin material of the meniscus member. (4) ^ After the physical property 'appropriately determined that the insert member has a rough surface. The rough surface is beneficial + & The method of forming the concave ridge is not particularly limited, but the method of opening the rough surface of the laser is simple. And better. In addition, regarding the formation position of the rough surface The area of the rough surface, the roughness of the rough surface after the f and the rear, and the effect of the present invention are exhibited by the relationship between the welded portion or the stress concentration portion of the thermoplastic resin member 0, which will be described later. m. In addition, in the case of using a laser to form a rough surface, the processing machine turns out the 丄古斤丄, the knife and the chasing width, the laser beam ώ rain power is 20~40W, and the chasing reward is 〇.〇2 ~〇.6ηπη, the laser beam spot is straight and the 仏 is about 130 # m is the range that is usually used. In addition, the first picture is the concept that the main table does not chase the width (the circle in Fig. 1 represents the vein) Irradiation of the laser of the wave. * Scanning direction. The shape of the insert member that is not laser-exposed in the front of the white plate is not particularly limited, and may be a simple shape of a quadrangular prism or a cylinder 10 201236846, or may be a church. The shape of the part is complicated, such as the shape of the part. The method of forming the rough surface is not limited, but for example, in the case of metal, it can be molded and shot by a conventionally known machine tool. Die casting, etc. The thermoplastic resin component may be a non-crystalline resin composition as a material for forming the thermoplastic resin member, or may be a general-purpose thermoplastic resin contained in the resin composition of the amorphous resin composition. Examples thereof include polyethylene (PE) 'polypropylene (PP), poly-4-methyl-anthracene, polycyclic hydrocarbon such as polystyrene, polystyrene (PS), AS resin, ABS resin, and gas gathering. Ethylene (PVC) polyacrylonitrile (pAN), (meth) acryl resin, cellulose resin, elastomer, etc. As a process resin, for example, nylon 6, nylon 6, 6, Snapdragon 12 Nylon 6'12 of various aliphatic polyamines or aromatic polyamines (PA), such as polyterephthalic acid (pET), polybutylene terephthalate (PBT), polynaphthalene dicarboxylic acid ( PEN) Aromatic Polyacetate, Polycarbonate (PC), Polyaldehyde (P0), Polyether Ether (PPE), Polyphenylene Sulfide (pps), Polysulfone (PSu), Polyimine (PI) , liquid crystal polyester, liquid crystal guanamine and the like. Further, it is also possible to use τ~το acid, an aliphatic diol, an aliphatic amino acid or an aliphatic polymer derived from the cyclized product, and further, these aliphatic polyesters which increase molecular enthalpy by using diisocyanate or the like may be used. Biodegradable resin, etc. Further, two or more kinds of the above resins may be used. Further, the resin composition contains substantially a small amount of impurities and the like, and is substantially composed of a crystalline thermoplastic resin. In particular, the thermoplastic resin member is composed of a crystalline resin composition such as a polyarylene sulfide (PAS) resin group 11 201236846 or a polybutylene terephthalate (PBT) resin composition. Since the thermoplastic resin member expands and contracts due to crystallization, the thermoplastic resin member is liable to cause cracking. However, according to the present invention, even when the thermoplastic resin member is composed of a crystalline resin composition, the problem of cracking of the thermoplastic resin member can be suppressed. Among the crystalline resin compositions, in particular, the PAS resin composition has properties such as high heat resistance, mechanical properties, chemical resistance, dimensional stability, flame retardancy and the like. Further, the PBT resin has properties such as mechanical properties, electrical properties, and chemical resistance. These resins having such excellent properties are used in automotive parts, electrical, electronic components and the like. Further, as the PAS resin which can be used, a milk resin as described in the publication No. 1 32935 can be mentioned. As the PBT resin which can be used, the PBT resin described in JP-A-2-61 1 693 can be cited. Moreover, PAS resins also have the disadvantage of being lacking in character and being fragile. Therefore, in the case where the thermoplastic resin member is formed using the PAS resin, the thermoplastic resin is particularly likely to be cracked when the insert molded body is disposed in an environment where the temperature changes greatly. However, according to the present invention, even if the resin (10) is used, the problem of cracking of the thermoplastic resin member can be sufficiently suppressed. Further, the resin composition (4) constituting the thermoplastic resin member may contain a conventionally known additive such as an oxidizing agent, a stabilizer, a plasticizer, or a pigment in the resin composition. The thermoplastic resin member of the present invention has at least one of a welded portion and a stress concentrated portion. 201236846 The welded part is formed by forming a thermoplastic in the cavity of the mold and in the resin: the other two resin flow parts. Whether or not the number of the nip portions, the number of the welded portions, and the welding are formed depends on the shape of the thermoplastic resin member or the position of the replacement member for forming the mounting member. "曰 The stress concentration portion includes a corner portion, a notch portion, a hollow portion, and a flow mark portion. The location or size of the a* bei hole and the stress concentration part of the temple can also be changed from the shape of the plastic resin member 黧m + m to the special feature of the heat. In the case where the method is specific to the law, it is possible to actually insert the thermoplastic resin member into the door. The shape of the member which is easily ruptured or the simulation or the like is not particularly limited. The insert member is placed in the mold using a mold having a desired cavity, and a resin composition in a molten state flows into the cavity to solidify the resin composition, whereby a desired shape can be formed on the insert member. Thermoplastic resin member. <First Embodiment> An insert molded body of the first embodiment will be described by taking an insert molded body shown in Fig. 2 as an example. Fig. 2 is a view schematically showing an insert molded body of the i-th embodiment, wherein (a) is a perspective view. (b) A plan view of (4): Fig. 3 is a perspective view schematically showing an insert member. The Fig.* is a schematic view showing the state in which the welded portion is formed. As shown in Fig. 2, the insert molding body 丨 has an insertion member 丨1 and a thermoplastic resin member 12 (hereinafter simply referred to as a resin member 12), and the resin member 12 is formed to cover one portion of the insertion member u. In the case of the first embodiment, the resin member 12 is formed on the insertion member 11 with the member member u inserted through the rectangular parallelepiped resin member 12. Then, the insert molding bottle manufactured by the mold having the mouth on the bottom side is shown in Fig. 2(a), and when the resin member 12 is formed, the welded portion 12 is generated at four places. As shown in Fig. 2, since the insertion member has four corner portions, the armature member 12 has four stress concentration portions, and the positions of the stress concentration portions and the welded portion 12. The position is the same. The insertion member 11 is closer to the bottom side than the two-dot chain line shown in Fig. 3. The portion where the bismuth is in contact with the resin member 丨2. The rough surface 11〇 is formed on the surface in contact with the sapling member 12. In the present embodiment, as shown in Fig. 3, a plurality of rough faces 11' having a rectangular shape (long side, short side L2) are formed on the side surface of the insertion member 11. The rough surface 110 is formed on the surface of the insertion member 大致 so as to be substantially parallel to the direction in which the welded portion 12A described later extends, and is substantially parallel to the "parallel parallel" of the & king. The angle between the direction in which the welded portion 126 extends and the direction in which the rough surface u 延伸 extends is not particularly limited as long as it has the effect of the present invention, but the included angle is 2. The following is better. In the first embodiment, as shown in Fig. 3, the rough surface 110 is formed in the vicinity of both ends of each side surface so that the two rough surfaces 110 are arranged in parallel. The position at which the rough surface 11 0 is formed may be in the vicinity of the area immediately below the welded portion 丨2 〇. For example, there is no problem if the distance from the welded portion 12 is about 2 mm. On the other hand, from the viewpoint of operability, the shortest is about 〇. 〇· 2 mn ^ In this embodiment, since the position of the joint 14 of the welding 14 201236846 is on the ridge line on the side of the insertion member, the "nearby" 疋The distance from the ridge line to the rough surface 11 , is indicated by L in Fig. 3, and the distance between the welded portion 120 and the rough surface 110 refers to the position at which the welding portion 120 and the rough surface 110 are closest to each other. the distance between. Further, in the present embodiment, the positions of both ends of the rough surface 110 in the direction in which the welded portion 12A extends are substantially the same as the positions of both ends of the welded portion 12' (long side L, < from the broken line to the insertion member u The length of the bottom surface is Lp). "Immediately-induced" means that it can also be the rough side! The positions of the ends of the one turn are slightly inside the positions of the both ends of the welded portion 12A in the predetermined direction. "Slightly inside" is only a range which is not harmful to the effects of the present invention, and the length thereof is not particularly limited, = each end. The difference between the lengths of the parts is as long as 1 of the long side. Within %, it is better within ^ 5:. Further, in the present invention, it is preferable to transmit the side of the square and the outer side of the rough surface of the predetermined direction. The position of both ends of the welded portion 120 in the 疋 direction is "the length of the new side L2 is larger than the side of the side parallel to the insertion member m L2 by 1/3 to 1/15, preferably 4 ,, and needs to be formed and connected. It is more preferable that the thicker surface of the resin is more y, and the longer the short side is required. The rough surface m uses the wrong effect to improve the adhesion of the resin member 11. The method of forming the rough surface of the member (1) There is no particular limitation, and a method can be used. For example, a method of forming a rough surface by a laser etching treatment to form a rough surface is preferred. method. In particular, the formation of the rough surface by the laser treatment is as described above, and the resin structure 4 is intended to have the welded portion 120. The tan junction 120 is formed as shown below in the following. The insert member n forming the rough surface 110 is set in the mold, and the molten thermoplastic resin is injected into the mold to be solidified. In the present embodiment, since the molten resin is emitted from the direction of the arrow Q in Fig. 4, the flow of the molten resin is divided into Q1 and Q2. Further, the welded portion 1 2 〇 is formed in the region where qi collides with the collision. In the present embodiment, the welded portion 12A is formed in a region surrounded by a dotted chain line as shown in Fig. 4 (only one of them is shown in Fig. 4 for convenience of explanation). The welded portion 120 is a rectangular region. One of the long sides of the welded portion 12 () is located at a position overlapping the side of the insertion member U. Weld η. The short side is overlapped with a part of the line connecting the upper surface and the bottom surface of the resin member 12 as shown in Fig. 4 . Next, the effect of the insert molded body of the first embodiment will be described. In the insert molded body i of the first embodiment, the rough surface 110 is formed on the surface of the insert member 11. In the portion where the rough surface 110 is formed, the adhesion of the insert member U to the resin member 12 becomes strong. As a result, even if the insert molded body of the first embodiment A is exposed to an environment having a large temperature change, the expansion and contraction of the resin member 12 are suppressed by the portion having a strong adhesion, and the turtle is formed on the surface of the resin member 12 by the P. crack. This effect is more specifically explained. Figure 5 is a schematic view for explaining the effect of the present invention, wherein the insert of the present embodiment is perpendicular to the two views, and (5) is formed in a direction perpendicular to the direction in which the welded portion extends. The rough surface (4) extending in the direction is a front view of the insert molding body on the surface of the insert, and a front view of the insert molding body 201236846 in the case of forming a rough surface. The sot insert molding body 1 is welded to the surface of the resin member 12, and borrowed! Second, there is a high probability of cracking. In the present embodiment, the rough surface 110 shown by *white= is formed in the insertion member, and even if the η:tight: force contraction, the resin member 12 and the insertion force are strong, because the contraction movement is hindered, so the contraction amount can be suppressed. . By suppressing the amount of shrinkage, the reduction effect reduces the burden on the resin member 12, and it is difficult to crack. Further, the occurrence of cracks is efficiently suppressed by the rough surface 11G extending in the direction in which the welded portion 120 extends, and the surface of the rough surface 110 which is required to be formed is suppressed. Further, as will be described later, when the area of the rough surface U 0 is large, a problem occurs. Further, as shown in Fig. 5 (4), the resin of the portion of the welded portion 12G can be made by sandwiching the welded portion 120' between the rough surface 110 formed by the insertion member u even if the resin in the direction of the blank arrow is reduced. The amount of shrinkage becomes smaller. Since the insertion surface 11 and the resin member 12 are firmly adhered to each other by the rough surface m formed on the surface of the insertion member i i , the welding portion 12 抑制 is prevented from contracting. As a result, even if the insert molded body i of the present invention is exposed to an environment having a large change in the degree of abundance, the shrinkage and expansion amount of the resin member 12 in the vicinity of the welded portion i20 are reduced, so that the shrinkage acting on the welded portion 12 can be reduced. Or the burden of swelling, and can inhibit the occurrence of cracks. The occurrence of cracks can be greatly suppressed by the position of both ends of the rough surface 110 in the predetermined direction being substantially equal to or more than the position of both ends of the welded portion 120 in the predetermined direction. In the case of the 201211846 in which the rough surface 11〇 shown in Fig. 5(b) is formed in the insertion member n, for example, since only a small portion is likely to be damaged due to shrinkage (in the present embodiment, the welded portion) 12Q), the shrinkage of the resin member 12 is hardly hindered, and the effect of improving the thermal shock resistance is hardly obtained. X, in the rough surface extending perpendicularly to the direction in which the welded portion shown in Fig. 5(b) extends, in order to sufficiently suppress the shrinkage of the resin in the vicinity of the welded portion, the area of the rough surface becomes excessive (i.e., it is required When most of the surface of the insert member that overlaps the resin member forms a rough surface, the area of the rough surface becomes too large, which tends to cause changes in physical properties such as conductivity, and the creativity is lowered. Further, after the rough surface is formed, when the surface of the insert member including the rough surface is subjected to the electro-silver treatment, the electric clock layer is formed on the uneven surface of the rough surface, and the adhesion between the resin member and the insert member is not strong. Propensity. As shown in Fig. 5(c), when the insert member is not formed with the rough surface 110, the shrinkage of the resin member and the amount of expansion of the resin member cannot be made small, and the burden of acting on the resin member 12 due to contraction and expansion of the resin member cannot be suppressed. . In the present embodiment, the rough surface is formed on the surface of the insertion member 2 by laser processing. If the method of forming a rough surface by laser treatment is used, since the local treatment is also easy, it is easy to form the rough surface in a desired range. In the above, the insert molded body of the i-th embodiment has been described. However, as shown in Fig. 6(a), the insert portion and the stress concentration portion may be the same. The insert molded body shown in Fig. 6 (4) is a portion of a side surface of a cylindrical member yak 12 which is covered with a cylindrical member inserting member u: a side surface of the resin member i2 is formed in the cylinder The direction of extension extends, field. The insert shown in Fig. 6(a) is formed into a stress concentration portion. Further, the welded portion 120 is formed so that the bottom of the groove is equivalent to the bottom of the groove. 18 201236846 Then, a rough surface 110 is formed in a region directly under the welded portion 120 of the ^11 π V-plane of the insert member 。. In the case where the rough surface 110 is formed in the region under the weld portion μ, μ. ^ female 4 Λ U, the shrinkage of the 曰μ, +. The occurrence of cracks is suppressed as in the case of the first embodiment which is not shown in the above Figs. 2 to 4M. Alternatively, for example, the insert molded body in which the welded portion and the stress concentrated portion are not included in the Fig. The insert forming system shown in Fig. 4(b) only has the shape of the groove of the tree member 12 which is different from the insert molded body shown in Fig. 6(a). . In Fig. 6 (^^, where the insert is not formed, the corner portion of the bottom of the groove and the PCT; #th thinner portion corresponds to the stress concentration portion. It is the same as the corner portion of the bottom of the groove. The position of the welded portion 120 is formed in the vicinity of the welded portion of the surface of the insert member. The area immediately below or the area of the positive: can be formed from 11 inches. In addition, the insert shown in Fig. 6 (8) Since the molded body has a plurality of stress concentration portions, a region in which the rough surface 'iU is directly under the stress concentration portion or a region directly under the stress concentration portion of the surface of the insertion member or the portion immediately below is formed When the rough surface 11 is formed in the vicinity, it is possible to suppress the occurrence of cracks in the stress concentration portion. Further, the insert portion may be formed in the welded portion and the stress concentration portion as shown in Fig. 6(C).
