The cross-sectional area of the head end portion 148 is larger than the cross-sectional area of the needle end portion 150. large area. The ejector pin 8 8 includes a head end 164 and a needle end 166'. The head end 164 corresponds to the head end portion 148, and the needle end 166 corresponds to the needle end portion 150. [0017] The fixing plate 134 includes a connecting surface 152 and a second fixing surface 154 facing away from the connecting surface 152, and a rotor having an internal thread 156 having a corresponding thread 128 extending through the connecting surface 152 and the second fixing surface 154 The through hole 158 and the four second fixing screw holes 160 corresponding to the first fixing screw holes 142. When assembled, the ejector pin 108 is placed in the thimble fixing hole 140. Specifically, the head end 098143053 Form No. A0101 Page 8 / Total 20 page 0982307867-0 201121764 〇 [0018] 164 is located in the head end 14β, the needle end is located in the needle end 150, and then the top plate 132 is placed on the fixing plate 134. The first fixing surface 138 is attached to the second fixing surface 154, and then the second fixing screw hole 160 and the first fixing screw hole 142 are screwed into the fixing plate by a dowel (not shown) to fix the top plate 132 to the fixing plate. 134. As such, the fixed plate 134 and the top plate 132 are combined into a ejector plate 106, and the thimble 108 is fixed in the ejector plate 106. The groove 丨 46 and the rotor through hole 158 constitute a rotor screw hole 162, the stud rotor 122 is received in the rotor screw hole 162, and the thread 128 and the internal threads 144, 156 are coupled to each other. Thereby, the ejector pin 106 is rotatably fixed to the stepping horse 10 f. It can be understood that the ejector plate 106 in this embodiment is divided into a top plate 132 and a fixed plate 134, and the thimble is divided into a head end 164 and a needle end 166. The thimble fixing hole 140 includes a head end portion 148 and a needle end portion 150. Fix the ejector pin 108. However, the invention is not limited thereto. For example, the ejector plate 1 can be integrally formed, and the ejector pin 108 is also integrally formed with the ejector plate. [•0019] It can be understood that the number of the thimbles 108 provided on each of the thimble boards 106 can be determined according to the specific circumstances, and is not limited to four in the present embodiment. Referring to FIG. 2 and FIG. 5, the template 20 0 encloses an ejector face 202 ′ a bearing surface 204 facing away from the ejector face 202 and defines four second positioning through holes 206 corresponding to the positioning posts 300 . The ejector face 202 is provided with eight ejector holes 208 corresponding to the eight ejector pins 108 respectively. The bearing surface 204 is provided with two ejector plate grooves 21 〇 'pin holes 2 〇 8 for accommodating the two ejector pins 106 and The ejector plate grooves 210 are in communication. The ejector plate groove 210 is for accommodating the ejector plate 106 and the depth of the ejector plate groove 210 is greater than the height of the thimble plate 1 〇 6 so that the ejector plate 106 can be along the ejector plate groove 210 in the ejector plate groove 210 Depth of direction activity. When assembled, the template 200 is passed through the positioning post 3 through the second 098143053 Form No. A0101 Page 9 / Total 20 pages 0982073867-0 201121764 $ 4 Vertical through hole 2 〇 6 and positioned above the fixed plate 10 0 。. Thus, the ejector pin. Table 06 is accommodated in the ejector plate groove 2ΐα., the thimble 108 is received in the thimble hole 2〇8' and the ejector plate 106 and the ejector pin 108 can be driven by the stepping motor 1〇4 to be recessed or The ejector face 202 is projected. [0021] It will be understood that the spring 110 is intended to buffer the speed at which the template 200 covers the fixed plate 100. A spring 11 也 may also be omitted on each of the thimble plates 106. [0022] It can be understood that the positioning post 300 can also be directly formed on the fixing plate 1 and the mutual positioning of the fixing plate 100 and the template 200 can be realized, so that the base 400 does not need to be provided. 〇[0023] When the product is generated on the top surface 202 of the board 200, the stepping motor 104 is turned on, and the stepping motor 104 drives the thimble board 1 due to the mutual screwing action between the stud rotor 122 and the rotor screw hole 162. The crucible 6 is moved upward to cause the ejector pin 108 to protrude from the ejection face 202 of the template 200, thereby ejecting the product. Since the ejector pin is ejected under the control of the stepping motor 104, the speed of its ejection can be accurately controlled to avoid damage to the product during ejection.
