TW564216B - Method for forming a handgrip sleeve of a wrench hand tool - Google Patents

Abstract

This invention provides a method for forming a handgrip sleeve of a wrench hand tool, particularly to one for resolving the technical problems resulting from the forging (casting) tolerances when the handgrip sleeve is applied to the wrench hand tool by means of over-molding. According to this invention, an independent rigid plastic sleeve serves as a mold-closing interface between the wrench handgrip and the mold cavity, so as to resolve the problems regarding mold clamping clearance or damages resulting from forging (casting) tolerances of the wrench, so as to eliminate seeping of plastic liquid from the handgrip sleeve, and to ensure the mold is able to provide the rear section of the handgrip with a sealed configuration. As such, upon injection forming the handgrip sleeve, the handgrip sleeve may be steadily embedded and coated over the rear section of the handgrip, while ensuring the appearance of the final product and industrial applicability.

564216 五、發明說明（l) -----— <發明之技術範圍> 本發明係關於一種扳手工具之握柄套成型製法，其主 要是以一硬質塑膠套件作為扳手握柄與模具模口之閉&介 面，藉以特可解決扳手鑄（鍛）造公差所衍生之夾持餘隙 或夾損問題，據以在達成握柄套之射出成型作業時，特能 維持其外觀品質，有效解決習知扳手工具握柄套 諸多缺失者。 <發明之背景說明> 按’一般用以操作螺栓（帽）鎖卸作業之扳手工具， 因其操作上係採扳轉模式施力，為顧及其操作之穩定性及 握持=舒適性，通常會於扳手握柄末端包覆結合一段握柄 套，藉以增加手部握持之觸感及磨擦係數，俾使其在扳轉 施力操作時，不致因手汗而導致滑脫現象，據以增進盍操 控之穩定者。 〃 μ 以傳統的扳手工具觀之，請參閱第1、2圖所示，其 於握柄套（2 0 )的附加上，主要是以模具先行射出成型 製造握柄套（20)，於握柄套（20)置設有相符於扳 手握柄（1 0 )後段尺徑之插結孔（2 1 )，藉以可將扳 手握柄（1 0)後段直接***握柄套（2 〇)的插結孔（ 2 1 )内而完成其結合，並為增加其結合之牢固性，通常 會於握柄套（20)之插結孔（2 1 )與扳手握柄（1 〇 )間上膠，據此於該等膠劑乾凝後，即可將握柄套（2 0 )穩固膠合固定於扳手握柄（1 〇)末段。 前揭扳手工具之握柄套採膠合固定方式，雖在作業上564216 V. Description of the invention (l) ------< Technical scope of the invention > The present invention relates to a method for forming a handle cover of a wrench tool, which mainly uses a hard plastic kit as the handle handle and mold of the wrench. The closing & interface of the die can specifically solve the problem of clamping clearance or damage caused by wrench casting (forging) tolerances, so that it can maintain its appearance quality when the injection molding operation of the grip sleeve is achieved. , Effectively solve the lack of many known wrench tool grip sleeves. < Background description of the invention > According to the wrench tool generally used to operate the bolt (cap) locking and unloading operation, since the operation is performed in the toggle mode, the stability and grip of the operation are taken into consideration Usually, a piece of grip cover is wrapped and combined at the end of the handle of the wrench to increase the tactile sensation and friction coefficient of the hand, so that it will not cause slippage due to hand sweat when it is turned and applied. Based on the stability of the puppet control. 〃 μ Seen from the traditional wrench tools, please refer to Figures 1 and 2 for the addition of the grip cover (20), which is mainly made by mold injection molding to make the grip cover (20). The handle sleeve (20) is provided with an insertion hole (2 1) corresponding to the diameter of the rear section of the wrench handle (1 0), so that the rear section of the wrench handle (1 0) can be directly inserted into the handle sleeve (2 〇). The joint is completed in the insertion hole (2 1), and in order to increase the firmness of the connection, the glue is usually glued between the insertion hole (2 1) of the grip cover (20) and the wrench handle (1 〇). According to this, after the adhesives are dried, the grip sleeve (20) can be firmly glued and fixed to the end of the wrench grip (100). The handle sleeve of the front wrench tool is glued and fixed.

Description of the invention (2) Seems quite simple, but in fact it has the following shortcomings: Its. Because of the jointing and gluing of the handle sleeve and the wrench handle, it all depends on manual methods, not only quite Trouble and time consuming]: Easy; The problem of potting, coupled with the limitation of glue drying time, leads to low overall operation efficiency, which will affect its cost and quality. Secondly, because the wrench handle and the handle cover are glued and fixed by an adhesive, the quality will be related to the combination of the handle cover and the convenience and convenience. The insertion hole of the handle cover will usually increase: the relative increase The use of glue #, and easy to have inadequate glue Q: The grip sleeve makes it easy to loosen or fall off during operation. That is, the grip sleeve of the traditional wrench tool is designed to be glued and fixed, because the total = glue is not strong, etc. The lack of it seriously affects the quality of the wrench tool, so = 2 people are in addition to the functional structure of the wrench guard, and the other-urgently needed to be solved =. To solve this problem, although some industry players have tried to use the mold to shoot the grip directly Overmolded at the end of the wrench handle, the following problems are encountered: * Please refer to Figure 3 for the upper part of the operation. Therefore, wrench-type tools are made in the w method, and there will inevitably be tolerances in manufacturing. In the closed mold clamping of the mold ^ 1), there may be a clamping clearance between the mold opening and the wrench handle (i Q) Pa1 due to the size of the wrench tool, or = I is slightly larger, and the mold occurs. The surface grip of the mouth-to-wrench handle (i 0) looks like '当 其 模 （ 1) Between the die opening and the wrench handle (i 0):

Description of the invention (3) When there is a clearance, the glue of the grip cover (20) may overflow from the clearance to form a rim. This not only affects the overall appearance, but also requires another Shi: Repairing while working will affect its overall quality and cost. If the hibiscus (1) is too tight against the wrench handle (10), you can :: damage the handle (10 ) The surface knot • will also affect its overall appearance. . Quality ’is really not conducive to the industrial system. Based on this, how to solve the wrench: the problem of the injection molding of the handle cover derived from manufacturing tolerances, is the research and development target. Qiao Gexinyue < Brief description of the invention > Urgent need: C wrench tool grip cover is glued and fixed. There is a problem that I want to shoot the grip cover to mold and cover it on the surface. Based on this' The inventor specially researched and improved the i: After two trial productions and multiple experiments and improvements, the invention's production method was finally developed, that is, its main purpose is to provide a method of wrench holding Yagi 4 ..., injection molding, And can effectively solve the problems caused by the poor manufacturing of wrenches. Taking another 5 months, another purpose is to use its handle sleeve forming method, outside the basin :. In addition to the good combination of the holster and the wrench handle, it is also the maintainer of the appearance quality of the soldier. The other purpose of the presentation is to give its grip sleeves a two-color vision, which can effectively show their brand image and value. For the purpose of the rubber sleeve, the design of the present invention is mainly based on-a hard plastic wrench! The closed mold interface of the grip and the die mouth is used to solve the clamping clearance or damage problems caused by tolerances. According to 564216 V. Description of the invention (4) When the injection molding operation is performed with a grip handle sleeve, it can maintain its appearance to temporarily solve the many shortcomings of the conventional wrench tool grip sleeve. < Detailed description of the invention > $ -Brake if: It provides a method for forming the handle cover of a wrench tool, especially the two-f rubber kit as the handle of the wrench guard and the mold mold. In this way, the grip sleeve can be molded by the injection molding method to directly cover the second truss door to the rear of the shank ', which effectively breaks the technology H derived from the wrench tool manufacturing tolerances and can also maintain its overall appearance quality.
