Problem to be solved: to prevent the occurrence of short shots when the resin molding for the pest control is produced by injection molding.SolutionIn the method of manufacturing the outer frame and the resin mold for pest control, in which a plurality of reinforcing members and a plurality of angular members are disposed inside the frame, by injection moldingAfter the resin composition containing the volatilization insecticide and the resin is filled into the injection molding machineThe total sum of the lengths of the outer frame, the angular material, and the reinforcing member is determined to be a (CM), the number of gates provided in the mold used in the injection molding is B (individual), and the load is measured at a temperature of 2.16 KGF and at a test temperature of 190 When the value of the melt flow rate (g / 10min) is set to C, C(a) a / (b * c) ≦The method of manufacturing the resin molding for pests control by satisfying the injection molding into the mold.Diagram【課題】射出成形で該害虫防除用樹脂成形体を製造する際に、ショートショットの発生を防ぐことを課題とする。【解決手段】外枠体、及び該外枠体の内側に複数の補強部材及び複数の角材が配されてなる害虫防除用樹脂成形体を射出成形により製造する方法において、揮散性防虫剤と樹脂を含有する樹脂組成物を射出成形機に充填した後、前記外枠体、前記角材、及び前記補強部材のそれぞれの長さの総和をa(cm)、前記射出成形にて使用される金型に設けられたゲートの数をb(個)、前記樹脂組成物のJIS K7210に基づいて荷重2.16kgf、かつ試験温度190℃で測定されるメルトフローレート(g/10min)の対数値をcとしたときに、(式) a/(b×c)≦200を満足させて、前記金型内に射出成形することを特徴とする害虫防除用樹脂成形体の製造方法。【選択図】図1
