Description of the invention: [Technical field to which the invention pertains] [Face] The present invention relates to an injection molding machine that emits a medium-moving structure, and in particular, a liquid plastic material that is first slid into a mold, and then The segmentation action of the injection is to improve the load on the motor and to improve the yield of the finished product. [Prior Art] According to the action of the injection molding machine, the steps are to close the mold, inject, shoot, hold, store, retreat, cool, mold and support. When the plastic material is heated and melted into After the liquid state, the liquid plastic material to be melted is injected into the closed mold, and then pressure is applied to fill the mold with the liquid plastic material, and then kept for a short time, after the plastic material in the mold is cooled and solidified, and then the mold is ejected. Finished product. Most of the existing plastic injection machines are driven by oil pressure, but the oil injection machine has a large energy consumption, 'easy to leak oil' and the control speed is slow, and the injection machine controlled by the feeding machine can improve the oil pressure injection. Partially missing. In the existing servo injection machine, for example, U.S. Patent No. 5,129,808, which uses a single motor to drive two ball screws to drive a rear seat and a feeding motor and related mechanisms. Since the injection driving device is provided with a plurality of motion axes, Therefore, it is not easy to maintain mutual parallel, synchronous action and control precision, and the weight thereof is large, and the use of the upper pole consumes kinetic energy.

201111153 套（4 1 )係隨之轉動，以帶動與軸套（4 1 )相螺接 之傳動螺桿（4 2)往前作動，繼之，推動相連接之滑 動主件（3 2)及固接於滑動主件（3 2)之滑動從件 (3 1 )往前移位，而將固接於滑動從件（3 1 )之注 料螺桿（2 2)往前推移，以進行擠料之動作。 由上述結構及實施方式可知，本發明係具有如下優 點： 1. 本發明係設有入料機構、滑動機構與射出機構， 乃藉由入料機構之注料螺桿將注入之液態塑膠原料順暢 的攪入模具内，繼之，當液態塑膠原料幾近滿料時，會 產生一反推注料螺桿之反作用力，此時，與注料螺桿相 組接之滑動機構係受力後移，以緩衝該反作用力，隨之 ，驅動射出機構作動其傳動螺桿，以帶動滑動機構推移 注料螺桿前進，進行擠料射出成形之動作，據此，先將 液態塑膠原料順暢攪入模具之内，再做擠料射出之分段 動作，即可以減輕馬達作動上之負荷。 2. 本發明係設有入料機構、滑動機構與射出機構， 乃藉由入料機構將液態塑膠原料攪入模具内，之後，再 驅動射出機構，進行擠料射出之動作，如此，使液態塑 膠原料充分攪入模具後，再做擠料射出之動作，係可以 使射出成形之成品良率提高。 綜上所述，本發明實施例確能達到所預期功效，又 其所揭露之具體構造，不僅未曾見諸於同類產品中，亦 未曾公開於申請前，誠已完全符合專利法之規定與要求 ，爰依法提出發明專利之申請，懇請惠予審查，並賜准 專利，則實感德便。 098132254 表單編號A0101 第11頁/共24頁 0982055328-0 201111153 【圖式簡單說明】 [0005] 第一圖：本發明之整體剖視圖 第一圖：本發明之A-A剖視圖 第三圖：本發明之使用狀態圖 第四圖：本發明之次一實施例整體剖視圖 第五圖：本發明之β_Β剖視圖 第六圖：本發明之次一實施例使用狀態圖 第七圖：本發明之另一實施例整體刮視圖 第八圖：本發明之C-c剖視圖 第九圖：本發明之另一實施例使用狀態圖 [0006] 【主要元件符號說明】 (1 ) 機台 (11) 軸孔 (12) 轴孔 (2 ) 入料機構 (21) 入料座 (211)入料口 (212) 注料孔 (22) 注料螺桿 (23) 入料馬達 (231)傳動軸 (24) 轉盤 (25) 傳動帶 (3 ) 滑動機構 (31) 滑動從件 (32) 滑動主件 (33) 定位件 (331) 穿孔 (34) 轴承 (4 ) 射出機構 (41) 轴套 (4 1 1 )螺孔 (42) 傳動螺桿 (43) 轉盤 (44) 軸承 (45) 射料馬達 (4 5 1)傳動軸 (46) 傳動帶 098132254 表單編號Α0101 第12頁/共24頁 0982055328-0The 201111153 sleeve (4 1 ) is rotated to drive the drive screw (42) that is screwed to the sleeve (4 1 ) to move forward, and then push the connected sliding main part (3 2) and the solid The sliding member (3 2) is moved forwardly from the member (3 1 ), and the injection screw (2 2) fixed to the sliding member (3 1 ) is pushed forward to perform the extrusion. The action. According to the above structure and embodiment, the present invention has the following advantages: 1. The present invention is provided with a feeding mechanism, a sliding mechanism and an injection mechanism, which are smoothed by the injection screw of the feeding mechanism. Stirring into the mold, and then, when the liquid plastic material is almost full, a reaction force of the reverse injection screw is generated. At this time, the sliding mechanism combined with the injection screw is forced to move backward to The reaction force is buffered, and then the driving mechanism is driven to actuate the driving screw to drive the sliding mechanism to advance the injection screw to perform the extrusion injection molding operation. Accordingly, the liquid plastic material is smoothly stirred into the mold, and then the liquid plastic material is smoothly stirred into the mold. By performing the segmentation action of the extrusion material, the load on the motor can be reduced. 2. The present invention is provided with a feeding mechanism, a sliding mechanism and an injection mechanism, wherein the liquid plastic raw material is stirred into the mold by the feeding mechanism, and then the injection mechanism is driven to perform the action of extruding the injection, so that the liquid is After the plastic raw material is fully stirred into the mold, and then the action of extruding the material is injected, the yield of the finished product can be improved.
