Injection molding is a well-known system for manufacturing a variety of parts. The injection molding system introduces a glazing material such as a sleek plastic or a resin into a cavity in a mold until the cavity is filled. And hardening into the inner surface shape of the cavity, and after the molten material is hardened or solidified, the hardened or solidified material is taken out from the cavity. For injection molding, a manifold assembly is typically used to deliver the molten material from a portion of the injection or injection port to a majority of the cavity or to a plurality of points in the large-cavity. The TGGman U.S. Patent No. discloses an example of such a manifold assembly, and in this patent, the manifold U is comprised of a one-channel, one-piece prayer-shaped circular manifold. And at least - a nozzle extending radially outward from the manifold and having a passage for the molten material to pass through. The end of the nozzle passage is referred to as a revolver and the cavity of the disc is fluidly connected. However, the manifold assembly is preferably not a caster, and the manifold assembly is preferably mechanically added from a single piece. In addition, it is preferred to provide a machined manifold that is generally circular in shape and has a generally circular cross-sectional shape. Therefore, in the case of the genus technical towel, it is necessary to provide a manifold assembly that can be turned over. 20 1277501 Thus, the present invention is capable of transporting a molding material from a source of molding material to a manifold in a mold. The manifold includes a main flow member and the main flow member defines a central flow passage extending through the member along a longitudinal axis of the main flow member. The main flow member also has a branch passage transversely and fluidly communicating with the center/port 5 passage, and further, the main flow member has a substantially circular outer surface having a cross section, and the outer surface is Machined to have a substantially circular cross section. Additionally, the present invention is a method of making a source of injection molded material to a mold. The method includes the steps of providing a rod having a longitudinal 10 axis, and the method also includes machining the rod to form a central flow passage extending along a longitudinal axis of the rod, the plurality of each intersecting the central flow passage And the branch passages that are fluidly connected, and have a rough.

管112之一半圓化外表面Η5。如第9圖所示，該切割器132 在使該桿130之第二側138圓化時避開該等墊121並藉此在 該第二側138上形成該等墊121。 5 最後，該方法包括通過對應墊121形成前述多數分支通 道119之步驟。該等分支通道119可以任何適當之方式形成 與鑽孔，以與該中央流動通道114流體性地連通。 如此，可機械加工本發明之歧管112，且與鑄造操作相 較，在某些情形下，這製造方法可以節省成本。同時，該 1〇完成之歧官112包括一橫截面大致為圓形之經機械加工外 表面115。因此，如第1圖所示之帶狀加熱器28，或其他加 熱器（圖未示）可以使用在該歧管112之外表面115上，以加熱 $亥溶融射出成型材料。該圓形外表面115與該圓形中央流動 通道114使該歧管112在橫截面上極為對稱，藉此使熱可均 15勻分散通過該歧管112。因此，可改善該等成形零件之品質。 本發明已以一舉例之方式說明過了，且在此應了解的 是已使用之用語係以字的本質來解釋而不是要用來限制。 在了解前述揭示後，本發明可有許多變形例與變化 例。因此，在以下申請專利範圍之範缚内，本發明可以前 2〇 述特定方式以外之方式實施。 I：圖式簡單説明3 第1圖是本發明之經機械加工歧管總成的立體圖。

The machined manifold assembly 1 includes a threaded double nut 44 disposed at the end of the central flow passage 14 to cap the passages 14 and to facilitate removal of the third insulator 24 when needed. 10 The machined manifold assembly 10 includes a plurality of titanium reaction members 26, and the titanium reaction members 26 are detachably and diametrically coupled to the radially extending nozzles 16 by means of fasteners such as screws 54 and isolate the Tube 12 and a splint 40. In addition, the reaction members 26 are preloaded pads between the splint 4 and the manifold 12 and are supported when the pressure is generated in the manifold 12 when it is subjected to an injection molding process. . The machined manifold assembly 10 further includes at least one and preferably a plurality of electric heaters 28, and the heaters 28 are mostly detachably disposed around the circumference of the manifold 12 and around the nozzles 16 to provide The plastic is heated at a specific or predetermined temperature. The heaters 28 are formed as two half cylinders on the manifold 12 and connected in parallel with wires as a power source of the distribution box, and the semi-cylindrical system of the heaters 28 uses conventional clamping fixtures. The detachably is detachably held around the circumference of the manifold and around the nozzle 10. It should be understood here that the semi-cylinders of the heaters 28 are discontinuous on the circumference, and the technique of the invention generally forms a gap therebetween. 1277501 The machined manifold assembly 10 includes at least one and preferably a plurality of temperature measuring sensors 30 for monitoring the temperature of the molten material, and the detectors 30 are fixedly coupled to the manifold 12 Within the nozzle 16, and at a distance from the outer diameter of the flow passages 14, 17 and the outer diameter of the manifold 12 and the nozzle 16, through the manifold 12 and the sensor bore or hole 46t of the nozzle, such as Figure 4 shows. The temperature measuring sensors 30 can be thermocouples that are secured in the sensor holes 46 by means of set screws, and the positioning screws are positioned vertically through the longitudinal axes of the sensor holes 46. The screw hole is 5 inches. The sensors 3 are electrically connected to a power source such as an electrical distribution box and include a non-mine 10 steel braided wire shield member 52, which protects the heater wires (not shown) ) does not interfere with radio frequency noise, and therefore ensures accurate readings. Further, the heaters 28 and the sensors 30 are configured to be supervised in a plurality of defined areas around the injection system, and the multi-zone control helps to more accurately monitor and control the molten material throughout The temperature in the process is injected, so less heat loss and better mold are obtained. • At the time of the secret, the (10) material is injected into the manifold 12 via the charm inlet pipe 2〇 at high temperature and high pressure. The fused material then flows along the manifold to the nozzles 16 in a central weaning passage 14. Then, the molten material flows through the nozzle passages of the respective nozzles to reach the mold (not shown). The arc of the manifold I2 provided with the third insulator 24 having a curved amount can reduce the shear force of the molten material flowing through the round terminal 13 of the manifold 12, because the (4) __ is over 90 degrees (90 °) ) Corner. The heaters 28 maintain the molten material at a specific temperature monitored by the sensors 30 throughout the injection process. The multi-zone design of the heaters and sensors 28 and 30 respectively allows the operator to monitor the temperature of the fused material at any point or region throughout the system, thereby providing better control of the injection process and thus Get a better product. 5 - Referring to Figure 5, there is shown another embodiment of the machined manifold 12 of the present invention, and similar parts of the manifold 12 have a similarity to a hundred (just). In this embodiment, the machined manifold ι 2 includes a cylindrical main flow member 113 to define a surface 115 that is generally a circular cross-sectional shape. The primary flow member 113 is made of a metal material and the primary flow member 113 defines a central flow passage 114 extending therethrough along the longitudinal axis L of the primary flow member 113. Preferably, the central flow passage 114 generally has a circular cross section and is centered within the main flow member 113. The primary flow member m also defines a plurality of branch passages ι 9 that are transversely and fluidly communicated with the central flow passage 114, as detailed below, wherein the manifold 112 transports the injection molding material from a source of forming material. (not shown) is sent to the mold (not shown) via the central flow passage m and the branch passages ι 9 . It should be understood herein that the manifold ι 2 is machined to have a generally circular cross section and this shape allows heat to be more evenly distributed through the manifold 112. 20 The manifold 112 also includes a plurality of 塾i2i, generally indicated at 121, and each of the 塾m is cylindrical and extends outwardly from the outer surface (1) of the main flow member. Each of the turns 121 defines a flat, circular terminal 123 which is mechanically machined with the main component 113 and is described in detail below. As shown in Fig. 5, the branch channels 119 extend 11 1277501 through the corresponding pads in the pads 121 and are centered on the terminals 123 of the respective pads 121. In the illustrated embodiment, the manifold 112 includes six pads 121. Three of the pads 121 are longitudinally aligned on one side of the manifold 112, while the other three 5 are longitudinally aligned on the other side of the manifold 112. The pads 121 include an inlet pad 125 and a plurality of nozzles 127, and the inlet port 125 is identical to the nozzle pad 127, but the inlet pad 125 extends outwardly from the outer surface 115 of the main flow member 113. The special T-mouth 127 is further away. The injection port 125 is positioned on the manifold 112 and is sized such that the branch passage 119 extending through the injection port pad 10 125 can be coupled to the injection port 2 as shown in Figures 1 and 2. (not shown) fluidly connected. The nozzle pads 127 are positioned on the manifold 112 and sized such that the branch passages 119 extending through the nozzle pads 127 can be coupled to the nozzles of the nozzles 16 as shown in Figures 1 through 3 (not shown). ) fluidly connected. However, it should be understood herein that the position and size of the pads 121 can vary depending on the injection port and/or nozzle used. The manifold 112 of Figure 5 can be used in an injection molding process, and the manifold 112 is combined with other parts of the machined manifold assembly and disposed in an injection molding machine (not shown) An injection port (not shown) is in fluid communication with the branch passage 119 of the injection port pad 125, and the nozzles 2〇16 are in fluid communication with the corresponding branch channels 119 of the nozzle pads 127. In one embodiment, the terminals 123 of the pads 121 serve as pressure plates such that the injection ports (not shown) and the nozzles 16 can be pressed against the pads 121 to prevent the molten injection molding material from leaking. . Further, the end of the main flow member 113 inserts and seals the end of the central flow 12 1277501 channel 114. The primary flow member 113 can be inserted in any suitable manner, e.g., with a threaded double nut 44 as described in FIG. Next, the molten injection molding material is injected into the manifold manifold 112 through the injection port (not shown), and reaches the branch passage 119 of the injection port pad 125. The molten material machine flows through the central flow passage 114 and from the branch passages 119 of the nozzle pads I], and then the molten material flows through the nozzles 16 and into the dam (not shown). It should be understood herein that any number of insulators (not shown) of the first, second and second insulators of Figures 1 through 3 may be included in the singular, machined manifold assembly. 1 〇 At the same time, in the injection molding process, a plurality of heaters of the heater 28' as described in Fig. 1 may be disposed around the outer surface 115 of the manifold 112. As will be described in more detail below, due to the generally circular cross-section of the manifold 112 of Figure 5, the manifold 112 can be heated more uniformly and thus more uniformly heat the smelting material flowing therethrough. Therefore, the quality of the formed part 15 can be improved by using the manifold 112. ^ Referring now to Figures 6 through 9, there is shown a method of making the manifold 112 of Figure 5 of the present invention. In a first step, illustrated in Figure 6, the method includes providing a rod 130 and positioning the rod 130 in a conventional grinder as indicated at 131 to mechanically utilize any of the conventional cutters 132. machining. In a consistent embodiment, before the rod 130 is positioned in the grinder 131, a hole is longitudinally formed through the rod 130 to thereby form the central flow passage 114 and thus provide a rod for the rod 130 is a device that is fixedly coupled within the clamp 134 of the grinder 131. The rod 130 is made of metal and is selected by a round or rectangular block, and it should be understood herein that Figures 6 through 9 show 13 1277501 machining the rod 130 to form the manifold 112. Subsequent steps of the circular outer surface 115, the pad 121, the central flow channel 114, and the branch channel 119. As shown in Figure 7, the next step of the method includes machining the rod 130 until the rod 130 has a generally rectangular cross-sectional shape. The cut 5 is 132 can be actuated in any suitable manner, and the clamp 134 can rotate the rod 13 任何 in any suitable manner to create the rectangular rod 130. In this rectangular shape, the rod 130 has a first side 136, a second side 138 opposite the first side 136, and an edge 14〇 extending longitudinally along the longitudinal direction of the rod 130. It should be understood here that when cutting is performed, the final depth of cut will reach the depth of the terminal 123 of the pads 121. For example, the terminal 123 of the injection pad 125 can be seen in Figure 6, and when the rod 130 is cut to a deeper depth, the cutter 132 will move to avoid the pads 121, thereby forming such a Pad 121. Next, as shown in Fig. 8, the method includes the step of rounding the rod 130 such that the 116 of the manifold 112 forms the plurality of pads 121. In the embodiment 15, this step includes rounding the first side 136 of the rod 130. The cutters 132 pass over the rod 130 and thereby remove the edge 140 on the first side 136 of the rod 130 and produce a semi-outer surface 115 of the manifold 112. As shown in FIG. 8, the cutter 132 avoids the pads 121 when the first side 136 of the rod 130 is rounded and thereby forms the pads 121 on the first side 136. 20 Next, the method includes the step of rotating the rod 130 about the longitudinal axis L. In the embodiment shown in Fig. 9, the jig 134 of the grinder 131 rotates the rod 130 by one hundred and eighty degrees (18 inches) centering on the axis L. The method then includes the step of rounding the second side of the rod 130, as shown in FIG. As previously described, the cutter 132 passes over the rod 130 and removes the edge 140 on the second side turn 38 of the rod 130 by 14! 2775〇1 and produces a semicircular outer surface Η5 of the manifold 112. . As shown in Fig. 9, the cutter 132 avoids the pads 121 when the second side 138 of the rod 130 is rounded and thereby forms the pads 121 on the second side 138. Finally, the method includes the step of forming the aforementioned plurality of branch channels 119 through the corresponding pads 121. The branch channels 119 can be formed and drilled in any suitable manner to be in fluid communication with the central flow channel 114. As such, the manifold 112 of the present invention can be machined and, in some cases, can be cost effective in comparison to casting operations. At the same time, the completed profile 112 includes a machined outer surface 115 having a generally circular cross section. Thus, a strip heater 28, as shown in Fig. 1, or other heaters (not shown) may be used on the outer surface 115 of the manifold 112 to heat the melted molding material. The circular outer surface 115 and the circular central flow passage 114 provide the manifold 112 to be extremely symmetrical in cross-section, thereby allowing the heat to uniformly disperse through the manifold 112. Therefore, the quality of the formed parts can be improved. The present invention has been described by way of example, and it should be understood that the language Numerous modifications and variations of the present invention are possible in light of the foregoing disclosure. Therefore, within the scope of the following claims, the invention may be practiced otherwise than as specifically described.
