It relates to a method of integrally molding.
従来公知のこの種の製造方法としては、特開昭６０−１
２１１３号公報に記載されたものがある。A conventionally known manufacturing method of this type is disclosed in Japanese Patent Application Laid-open No. 60-1
There is one described in Publication No. 2113.

濾材２の内周に樹脂製中心部材を一体成形している。As shown in FIG. 14, for example, the outer circumference 2a of the filter medium 2
is longer than other parts (formed), and the outer periphery 2a of the filter medium 2 is sandwiched between a pair of split molds 7 and 8, and the outer periphery 2a of the filter medium 2 is
a is accommodated in a resin injection part 4', molten resin is injected into this resin injection part 4', and an annular resin flange is integrally molded on the outer periphery 2a of the filter medium 2. The inner periphery of the annular filter medium 2 is also disposed in the resin injection part with substantially the same configuration as described above, and a resin center member is integrally molded on the inner periphery of the annular filter medium 2.

濾材２の表面に付着する等の弊害をもたらす。However, according to the above manufacturing method, among the filter media 2,
The outer periphery is formed long on the extension line of the cross-sectional wave shape of the filter medium 2, and the outer periphery is oblique as shown in FIG. For this reason, the filter media clamping portions 7a and 8a of the mold 7.8 also form slopes, and the mold clamping force P against the mold 7.8 does not sufficiently act on the clamping portions 7a and 8a.
The molten resin injected into the sandwich parts 7a, 8a and the filter medium 2
leaks to the outside of the resin injection part 4' through the gap between the contact parts,
This causes problems such as adhesion to the surface of the filter medium 2.
［問題点を解決するための手段］
本発明は上述の問題を解決しようとするものであって、

一体成形するという技術的手段を採用する。[Means for solving the problems] The present invention aims to solve the above problems, and includes:
The flange portions of the filter medium, which has flange portions protruding in the radial direction on the inner and outer peripheries, respectively, and which are annular as a whole and have a corrugated cross section, are sandwiched between the sandwiching portions of a pair of molds having a split mold structure. , is placed in a resin injection part formed by the pair of molds, molten resin is injected into this resin injection part, and a technical means is adopted in which a resin member is integrally molded on the flange part of the filter medium.
〔作用］
本発明では環状濾材の内、外周の半径方向にフランジ部
を形成しているため、一対の成形型の挟み部によって環
状濾材のフランジ部を挟み込む際に成形型の型締力を上
記挟み部に確実に作用させることができる。[Function] In the present invention, since the flange portion is formed in the radial direction on the inner and outer periphery of the annular filter medium, when the flange portion of the annular filter medium is sandwiched between the sandwiching portions of a pair of molds, the clamping force of the mold is reduced to the above-mentioned level. It can be made to act reliably on the pinching portion.
従って、環状濾材のフランジ部をしっかりと成形型の挟
み部で挟み込むことができ、樹脂注入部に注入した溶融
樹脂が樹脂注入部から洩れ出るのを回避できる。Therefore, the flange portion of the annular filter medium can be firmly sandwiched between the clamping portions of the mold, and the molten resin injected into the resin injection portion can be prevented from leaking out from the resin injection portion.
このように本発明によれば、環状濾材に不必要な樹脂が
付着することがなく、品質面で優れる。As described above, according to the present invention, unnecessary resin does not adhere to the annular filter medium, and the quality is excellent.
また、樹脂洩れを防ぐために成形型の挟み部の加工精度
をよくする必要がなくなる。Furthermore, it is no longer necessary to improve the machining accuracy of the sandwiching part of the mold in order to prevent resin leakage.

A synthetic resin injection part 3' is formed for this purpose. The gates 11 and 12 communicate with the injection sections 4' and 3'. As shown in FIGS. 5 and 6, the filter medium 2 has comb portions 14' and 1 having shapes corresponding to the waveform shape of the filter medium 2 at three locations.
It is sandwiched between a pair of cores 14 and 15 at three locations having 5' at the end.

となり、容易に製作で−きる。From this FIG. 7, in the present invention, the flange 2b of the filter medium 2 has an annular and convex sandwich portion 7a provided in the mold 7.8,
The clamping portions 7a and 8a are opposed to each other in the same direction as the mold clamping force P. Therefore, since the flange 2b of the filter medium 2 is reliably sandwiched between the sandwiching parts 7a and 8a, the resin from the resin injection part 4' does not leak to the outside from the resin surface between the flange 2b and the sandwiching parts 7a and 8a. The occurrence of defective products due to leakage can be reduced. Further, since the mold clamping force can be directly transmitted to the sandwiching parts 7a and 8a of the mold 7.8, high machining accuracy and high mold strength are not required during mold manufacturing, and the mold can be manufactured easily.
