220、導執230與定位件240。定位裝置200可水平設置於 注射成型機（圖未示）。 導執230 —端垂直固定於第一夾板210,另一端垂直貫 通第二失板220’以使第二夾板220可滑動地設置於導執 230，從而第一夹板210與第二夾板220之間之距離可藉由 第二夾板220之滑動進行調整。 第一夹板210與第二夾板220相互平行。第一夹板210 設有第一定位通孔211，對應地，第二夾板220設有第二定 位通孔221。第一定位通孔211與第二定位通孔221之中心 軸線位於同一直線，且該直線平行於導軌230。第一定位通 孔211與第二定位通孔221分別與模具50之第一凸起物 5111及第二凸起物5221之形狀及尺寸適配，以使第一凸起 物5111及第二凸起物5221分別穿設於第一定位通孔211 與第二定位通孔221。

與固定板631配合夹持待定位模具。 固定板631還設有安裝孔6311。安裝孔6311供銷釘、 鏍釘或鏍栓等連接件將定位件640固定於第一夾板610與 第二夾板620。 當模具表面設有卡位槽時，定位件640之夾持板 6421a、6421b可相應地設置形狀及尺寸與該卡位槽匹配之 彈性固持件6422。該彈性固持件6422由彈簧與銷釘組合而 成，其於自然狀態之長度與夾持板6421a、6421b之高度匹 配。其藉由壓縮狀態下產生彈性形變而卡進模具表面之卡 11 200920586 位槽，然後於卡位槽中恢復形變，從而實現對模具卡位。 另外，當模具未設有卡位槽時，亦可於延伸板642上設置 彈性固持件，以微調模具於相對設置之二夾持板6421a' 6421b之間之位置。 使用本實施例之模具定位裝置600時，先使模具50與 二夾持板6421a、6421b之位置相對，然後使第二夾板620 帶動定位件640沿著導軌630朝第一夾板610滑動，直至 其將模具50推至第一夾板610之定位件640之二夹持板 6421a、6421b之間，如圖10所示。此時，公模51之第一 凸起物5111與第一定位通孔6311吻合，母模52之第二凸 起物5221與第二定位通孔6121相對。然後，繼續驅動第 二夾板620帶動定位件640朝第一夾板611運動，直至母 模52之第二凸起物5221進入第二定位通孔6121，且第二 夾板620不能移動為止，從而達成將待定位模具50固定於 第一夾板610與第二夾板620之間。 綜上所述，本發明確已符合發明專利之要件，遂依法 提出專利申請。惟，以上所述者僅為本發明之較佳實施方 式，自不能以此限制本案之申請專利範圍。舉凡熟悉本案 技藝之人士援依本發明之精神所作之等效修飾或變化，皆 應涵蓋於以下申請專利範圍内。

[Prior Art] As an indispensable part of material processing technology such as injection molding, extrusion molding and blow molding, molds play an increasingly important role in industrial production. For example, most of the parts of products in the fields of electronics, automobiles, motors, appliances, instrumentation, and communications are manufactured by mold forming. See also the following control of the mold filling process in an injection molding machine; Cheng-Ping Chu, Jong-Hwei Wei, Ming-Chang Shih; Department of Mechanical Engineering, National Cheng Kung University, Tainan, Taiwan, Republic of China; Polymer Engineering and Science; Volume 31, Issuel 5, Pages 1123~1129, Published online, 26 Aug 2004. At present, the fixing of the mold to the injection molding machine is mainly achieved by the matching machine of the injection molding machine and the movable table matched with the fixed table. Referring to Fig. 1, the fixed machine table 10 of the injection machine is disposed opposite to the motive table 20. The guide rail 30 is horizontally disposed, one end of which vertically penetrates the movable table 20, and the other end of which is fixed to the fixed table 10. The method for fixing the mold 40 by using the fixed table 10 and the movable table 2 includes the following steps: (1) suspending the mold 40 having a closed body and using a suspension device to make the first surface 411 of the mold 40 It is in contact with the clamping surface 11 of the fixed table 10 of the injection molding machine. (2) Adjusting the mold 40 200920586 Between the clamping surface 11 and the clamping surface 11, the suspension surface 412 of the replacement tool 4 is parallel to the guide rail 30, so that the mold 4 is at the horizontal position 2 So that it will follow the guide 3 〇 、 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , When using the two machines of the Zhuang injection molding machine to match the fixed mold, it is necessary to manually adjust the positional relationship between the mold and the clamping surface of the fixed table by using ^ „......., the steps are complicated. It takes a lot of time. In addition, whether the right armor is based on the visual judgment or not, and the wire is not in the horizontal position, the product of the continuous production will be less symmetrical. And in the hanging hang: Cheng: the relative mold between the male and female molds of the mold that has been clamped is easy to slip, and the center line of the V-induced male and female molds does not coincide, thus affecting the male mold cavity and the female mold cavity Concentricity' in turn affects the production of later products. This method is also susceptible to other positioning factors in its actual operation. For example, when an injection molding machine equipped with a robot arm is used to mount a mold, it is necessary to fix the mold to the injection molding machine in the above-described steps by not (4) moving the robot arm y 吏 between the movable table and the fixed table. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a mold positioning device that quickly and accurately positions a mold to an injection molding machine.

The two clamping plates 6421a, 6421b respectively have surfaces 6423, 6424, and the distance between the surfaces 6423, 6424 is equal to the height of the male mold 51 and the female mold 52 of the mold 50 to be positioned, so that the two clamping plates 6421a, 6421b and the fixing plate The 631 fits the mold to be positioned. The fixing plate 631 is also provided with a mounting hole 6311. The mounting hole 6311 is provided with a connecting member such as a pin, a stud or a bolt to fix the positioning member 640 to the first clamping plate 610 and the second clamping plate 620. When the surface of the mold is provided with a retaining groove, the holding plates 6421a and 6421b of the positioning member 640 can be correspondingly provided with the elastic retaining member 6422 having a shape and a size matched with the retaining groove. The elastic retaining member 6422 is formed by a combination of a spring and a pin, and the length of the natural state matches the height of the holding plates 6421a, 6421b. The card is inserted into the surface of the mold by elastic deformation in a compressed state, and then the deformation is restored in the card slot to achieve the clamping of the mold. In addition, when the mold is not provided with the retaining groove, an elastic retaining member may be disposed on the extending plate 642 to finely adjust the position of the mold between the oppositely disposed holding plates 6421a' 6421b. When the mold positioning device 600 of the embodiment is used, the position of the mold 50 is opposite to the positions of the two clamping plates 6421a and 6421b, and then the second clamping plate 620 is caused to move the positioning member 640 along the guide rail 630 toward the first clamping plate 610 until it is The mold 50 is pushed between the two holding plates 6421a, 6421b of the positioning member 640 of the first clamping plate 610, as shown in FIG. At this time, the first protrusion 5111 of the male mold 51 coincides with the first positioning through hole 6311, and the second protrusion 5221 of the female mold 52 is opposed to the second positioning through hole 6121. Then, the second clamping plate 620 is driven to drive the positioning member 640 to move toward the first clamping plate 611 until the second protrusion 5221 of the female mold 52 enters the second positioning through hole 6121, and the second clamping plate 620 cannot move, thereby achieving The mold to be positioned 50 is fixed between the first clamping plate 610 and the second clamping plate 620. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the present invention are intended to be included within the scope of the following claims.
