【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、合成樹脂製パレットに、滑り止め用部材を一
体的に成形するための合成樹脂製パレットの製造方法に
関する。Description: TECHNICAL FIELD The present invention relates to a synthetic resin pallet manufacturing method for integrally molding a non-slip member on a synthetic resin pallet.
従来では、例えば、滑り止め用部材を熱可塑性ゴム等に
よって中空棒状に予め形成しておき、その中空状に形成
した部分を利用してパレット用の金型に取り付けた状態
で、パレット形成用の樹脂を金型内に射出してパレット
用の樹脂と滑り止め用部材とを熱溶着されるようにして
いた(特開昭52−123044号公報参照)。Conventionally, for example, the anti-slip member is formed in advance in the shape of a hollow rod with thermoplastic rubber or the like, and the portion formed in the hollow shape is used to form a pallet while being attached to a pallet mold. The resin is injected into the mold so that the pallet resin and the non-slip member are heat-welded (see Japanese Patent Laid-Open No. 52-123044).
しかしながら、上記従来方法では、パレットとは別体に
形成された滑り止め用部材をパレット形成用の金型に予
めセットする必要があり、パレットの製造に手間がかか
る不利があった。However, in the above-mentioned conventional method, it is necessary to previously set the anti-slip member formed separately from the pallet in the pallet forming die, which is disadvantageous in that it takes time and labor to manufacture the pallet.
本発明は、上記実情に鑑みてなされたものであって、そ
の目的は、合成樹脂製パレットの生産性を改善すること
にある。The present invention has been made in view of the above circumstances, and an object thereof is to improve the productivity of synthetic resin pallets.
本発明による合成樹脂製パレットの製造方法は、合成樹

覆いを除去して滑り止め用部材形成用の樹脂を前記滑り
止め用部材の取り付け箇所に射出して、前記パレットと
前記滑り止め用部材とを、前記一つの成形用型内で一体
的に成形する点にある。A method for manufacturing a synthetic resin pallet according to the present invention comprises integrally molding a non-slip member on a synthetic resin pallet, the characteristic configuration of which is a mounting position of the anti-slip member of a molding die. After injecting a resin for forming a pallet in a state of covering, the resin for forming the anti-slip member is injected to the attachment site of the anti-slip member by removing the cover of the attachment site of the anti-slip member, The pallet and the anti-slip member are integrally molded in the one molding die.
つまり、成形用型に、パレット形成用の型部材と滑り止
め用部材形成用の型部分とを形成しておき、滑り止め用
部材の取り付け箇所を覆う状態でパレット形成用の樹脂
を射出した後、滑り止め用部材の取り付け箇所の覆いを
除去して滑り止め用部材形成用の樹脂を滑り止め用部材
の取り付け箇所に射出させることにより、一つの成形用
型内で、滑り止め用部材とパレットとが一体成形される
ようにするのである。That is, after forming a pallet forming mold member and a slip preventing member forming mold portion on the molding die, and after injecting the pallet forming resin in a state of covering the attachment position of the slip preventing member. , By removing the cover of the anti-slip member mounting portion and injecting the resin for forming the anti-slip member to the anti-slip member mounting location, the anti-slip member and the pallet are formed in one molding die. And so that they are integrally molded.
従って、パレットの形成と滑り止め用部材の形成とを、
一つの成形用型内で射出成形によって行うので、従来の
ように、予め滑り止め用部材を型内にセットする手間が
不要となる。もって、生産性を向上できるに至った。Therefore, the formation of the pallet and the formation of the non-slip member,
Since injection molding is performed in one molding die, it is not necessary to previously set the anti-slip member in the die as in the conventional case. As a result, productivity can be improved.
