Therefore, as indicated by the arrow in the figure, a disturbed state occurs in the resin flow, and segregation appears in the mixed state of the resin component and the glass fiber component mixed in the resin component, and a predetermined amount is generated. Occasionally, products that deviated from quality were generated. That is, in a bathtub or the like obtained after curing, color unevenness, exposure of glass fibers or surface cracks have occurred in the outer peripheral portion of the upper edge surface or the like. Therefore, the molding yield of the resin product was not so high.

樹脂の噴出効率が良い。(Operation) When the uncured resin flows to the outer edge of the molding space formed between both the lower mold and the upper mold, the resin becomes intimately adhered to each other. The resin is ejected to the outside of the die through a resin ejection passage that communicates with the outer edge corresponding portion of the lower die or the outer edge corresponding portion of the upper die as an inlet. Therefore, at the outer edge of the molding space, a dead end does not occur in the resin flow,
Therefore, there is no possibility that the resin component and the glass fiber component will be disturbed. Further, since the resin ejection passage communicates with the outside of the mold from the outermost edge corner position of the outer edge portion, the outermost edge surface of the outer edge portion of the molded product is beautifully finished and looks good. Further, since the resin ejection passage is formed with a passage portion obliquely upward in the range of about 30 ° to 60 ° from the horizontal direction,
Good resin ejection efficiency.
（実施例） 以下、本考案を、その実施例を示す図面に基づいて説明
すると次の通りである。(Embodiment) The present invention will be described below with reference to the drawings showing an embodiment thereof.

れるようになっている。FIG. 1 is a front sectional view of an essential part showing an optimum embodiment of the mold of the present invention, which is drawn for easy comparison with the conventional example shown in FIG. In the mold of the present invention, the lower mold 4 and the upper mold 5 are combined to form a resin injection passage 6 between the molds 4 and 5.

よって形成されている。The resin ejection passages 6 are a series of slit-shaped ones formed along the molding contour portion when the lower die 4 and the upper die 5 are molded, and are scattered along the molding contour portion. The inner surface of the lower die 4 is formed by the inner surface of the concave portion of the lower die 4, and the other surface is formed by the outer surface of the raised portion of the upper die 5. The resin ejection passage 6 is formed by a portion rising in the vertical direction and a portion inclined obliquely upward.

れら双方の作用を充分に発揮し得るようにするには、そ
の傾斜角度を45°にしたときが最適であった。In the resin ejection passage 6, the inlet portion 6a on the lower end side of the portion rising in the vertical direction has the pressing surface 4a of the lower mold 4.
It is positioned to match the outermost edge of the. Therefore, the resin melted or injected in the molding space formed between both the molds 4 and 5 is the inlet portion of the resin ejection passage 6.
When the resin reaches 6a, the resin suddenly flows into the resin ejection passage 6. Therefore, a dead end (disturbance state) does not occur in the resin flow at the outer edge portion, and the mixed state of the resin component and the glass fiber component is not damaged. In this embodiment, the height h of the vertical rising portion is formed to be about 15 mm, and the passage width is set to about 0.2 mm. On the other hand, in the resin ejection passage 6, a portion which is inclined obliquely upward following the vertical rising portion as described above is such that the resin is easily ejected from the inside of the vertical rising portion to the outside of the mold. In this embodiment, the inclination angle θ is formed so as to fall within the range of about 30 ° to 60 °. In addition,
In this upper inclined portion, the resin jetted out of the mold is blown away from the lower mold 4 and the upper mold 5 as far as possible, so that the peripheral portions of the pressing surfaces 4a, 5a of the respective molds 4, 5 become dirty. I also expected the meaning of preventing this. Therefore, in order to sufficiently exert both of these effects, it was optimal to set the inclination angle to 45 °.

劣るようなこともない。After the resin has been filled as described above, both molds 4 and 5 are released after curing of the resin is completed, and the molded product thus obtained is projected corresponding to the resin ejection passage 6. You just need to scrape off the fins. The portion where the fin-shaped portion projects is the lower side of the upper edge surface of the bathtub that is a resin product, and is a portion that cannot be seen even when the bathtub is commercialized and installed. Therefore, even if the fin-shaped portion is scraped off, it is not necessary to treat the remaining surface, and of course, the appearance is not deteriorated.

実施の態様に応じて適宜変更可能である。(Examination of Another Mode) The resin product molded by the mold of the present invention is not limited to a bathtub, and may be a bathtub apron, a unit plate for a prefabricated storage tank, or the like. Further, the mold of the present invention may be a combination of three members including a lower mold 4 and an upper mold 5 and also a frame mold (not shown). By the way, FIG. 2 is a front sectional view of an essential part showing an embodiment in which the resin ejection passage 6 is provided in the lower mold 4. As described above, the method of providing the resin ejection passage 6 can be selected from various methods according to the mold type, the outer shape of the resin molded product, and the like. In particular, the mold shown in FIG. 2 is suitable when the height h of the vertical rising portion of the molded product is short. In the mold of the present invention shown in FIG. 2, a cooling water circulation path (not shown) or the like is provided inside the thick-walled portion where the resin ejection passage 6 is arranged so as to surround the resin ejection passage 6. It is good to keep it. By doing so, even when the resin is cured in the molding space between the molds 4 and 5, the resin remaining in the resin ejection passage 6 is maintained in an uncured state. Therefore, if the compressed air or the like is blown into the resin ejection passage 6 after the molds 4 and 5 are released from each other, the resin can be cleaned and ready for the next molding. Thus, the structure and shape of the mold of the present invention are
It can be appropriately changed according to the embodiment.
