New Description: [New Technology Field] This creation is a water needle structure, especially a liquid needle structure that can inject high-pressure liquid into the cavity of the plastic injection molding die. Soil, [Prior Art] The general plastic injection molding technology, when forming hollow articles, the earliest method is to use blow molding (Bl0W Molding) or gas-assisted molding. This technology is often difficult to maintain due to difficult gas pressure control. The wall of the molded article is thin and steep, and due to the poor heat dissipation effect of the gas, the cooling time (Coo^n Time) of the mold is prone to be long, which further lengthens the production cycle of the product ((10)^τ_). g ^Improve the lack of the above-mentioned blowing money to be thrown, and more complete liquid-assisted, injection-faced techniques, such as Taiwan's new patent announcement No. 547315 "Water = assisted injection molding structure improvement" as shown in the "Figure ^" The liquid water is sprayed into the cavity 12 of the molding die n to form the middle two, , and . Compared with the technology of the first rhyme, it has the following advantages: 1. Due to the large recording (four), such as water can be regarded as an incompressible riding body, the liquid does not need high-emission _ force 'low pressure can be formed, and has a relatively uniform pressure distribution . 2. The liquid has a better cooling and cooling effect, which can shorten the molding cycle. Saves less clamping force, can use smaller maid injection molding machine, to reduce the wall thickness of the product, the wall thickness of the (4), the surface dent, the lower internal dust force, uniform The size of the constricted seat is female, and the deformation is small. M3 02466 6·Economic point of view··Save material, machine, and cost the temple, shorten the finished product production cycle, and improve production efficiency. However, in addition to the water injection action, the water-injection structure of the above-mentioned new announcement must also have the problem of preventing the liquid return of the mold towel after stopping the technical water, and the problem of counter-flow of the money channel, so it is necessary to design a similar single_ and switching structure, and The function is too numerous, resulting in too much structure and increasing the cost and failure rate. Secondly, the above-mentioned prior art design has a narrow water injection π cross-sectional area, and the fine main tree (10) is too high, so that the cavity is too high.

[New content] In view of the above-mentioned lacks, the problem to be solved in this case is to provide a streamlined water-needle knot that can be used for abundance and bribery. In order to solve the above problems, the present invention provides a liquid-assisted injection molding water needle structure 'including an outer sleeve, a sieve plate and an inner sleeve f. The outer sleeve is fastened to the mold for injection molding, the outer sleeve has a water inlet hole for the liquid or water to be injected, and the outer sleeve has a water outlet hole at the other end, and is located in the cavity of the mold, and the water outlet hole The periphery of the formation - the extension of the extension. The plate is placed in the outer sleeve and abuts against the abutment. The inner sleeve is threaded into the outer sleeve, and the outer diameter of the sleeve is matched with the inner diameter of the outer sleeve, and the sleeve is closed to the sieve plate. Thereby, the high-pressure water can be connected to the water inlet hole, so that the water liquid can be injected into the cavity through the inner casing and the water inlet hole; and because the water inlet is provided with the sieve plate, the high viscosity in the hole can be blocked. The liquid plastic liquid with lag coefficient flows into the water system in reverse flow. (4) The plate can still provide the large channel cross-sectional area, so that the water flow rate can be reduced and the flow field stability can be improved under the premise of constant water injection. By adopting the above structure of the present invention, the simplified design of the M302466 structure can be obtained compared with the prior art, but the structure of preventing the backflow of the plastic liquid is reduced, and the failure is reduced. However, (4) Bu's and the division can turn a larger cross-sectional area for assistance so that the body can be simplified and lower, so that the flow field is more stable, so that the inner surface of the product forms a smooth quality. The detailed description of the new features and the advantages of the novel are sufficient for any skilled person to understand the technical content of the present invention.

F 狂毛贝 [Embodiment] The following description of the drawings and the preferred embodiments or examples are described below. For the first time, please refer to the cross-sectional view of the combined state of the "2nd ®" scales and the three-dimensional exploded view and "3rd figure". The water needle structure 20 includes an outer sleeve 2, a screen plate 22 and an inner sleeve 23. The structural composition is detailed below. A jacket 2 is formed inside the jacket 21, and the outer sleeve 21 has a water inlet hole 212 at one end thereof and communicates with the passage 211. At the same time, the other end of the outer sleeve 21 is provided with a water outlet hole 213 communicating with the passage 211 and a hole of the water outlet hole 213. The rim forms an abutment portion 214 that extends inwardly. The screen plate 22 is placed in the outer sleeve 21 and abuts against the abutting portion 214 for partitioning the passage 211 from the water outlet hole 213. The screen plate 22 is formed with a plurality of meshes which maintain sufficient passages _ for the passage of the auxiliary body or water and reduce the flow rate of the auxiliary liquid or water while the water injection amount is constant. Through the 4-inch nature of the small pupil, the fluid with a south viscosity coefficient, such as plastic liquid, cannot pass because of the viscous resistance M302466. The inner sleeve 23 is inserted into the passage 211 of the outer sleeve 21, wherein the outer diameter of the inner sleeve 23 is matched with the inner diameter of the passage 211, and the inner sleeve 23 is end-to-end and closes to the sieve plate 22' to the sieve plate 22 It is fixed to the abutting portion 214. A schematic diagram of liquid-assisted injection molding of a preferred embodiment of the present invention, as depicted by Beiming, "Tea 4A" and "4B". The water needle structure 20 after the assembly is assembled as described above is used in conjunction with a plastic injection molding machine (not shown), and the working medium can be the lowest cost and the easiest liquid water. Firstly, an external thread 215 can be provided on the surface of the outer sleeve 21, and a groove 216 on the top surface of the jacket 21 can be used to fit a wrench tool (not shown) and screwed into two plastic molding molds. In one of the 30, the water outlet hole 213 of the outer sleeve 21 is placed in the cavity 31 of the mold 3, and is injected into the short shot by the plastic liquid injection port a; the glue-like plastic night 40 is in the cavity 31. Thereafter, the liquid 5〇 (such as water) is controlled to enter via a control valve switch (not shown), and then connected to the high pressure liquid injection port B via the high pressure hose, that is, the water inlet hole 212 of the water needle structure 2, the inner casing 23 And passing through the sieve plate 22, and injecting into the cavity 31 through the water outlet hole 213 to push the sol-like plastic liquid 40 to advance, thereby hollowing out the center portion to complete the filling process. Because the sieve plate 22 of the present invention is porous, the "microporous" property formed by the present invention allows the liquid 50 such as water having good fluidity to pass freely, increases the water flow rate, reduces the flow rate, and improves the flow field stability, so that The inner surface of the plastic injection finished product is smoother. Moreover, it is possible to prevent the plastic liquid 4 having a high viscosity coefficient and poor fluidity from flowing back into the channel 211 in the mold 61. For the continuation, please refer to the cross-sectional view of the combined state of the other embodiment shown in FIG. 5 and the combined state shown in FIG. The water M302466 needle structure 20' of the present embodiment replaces the above-mentioned porous material sieve plate 22 with a high-density stainless steel mesh 221, but it is considered that the high-density stainless steel mesh 221 is insufficient in lateral strength and is easily bent. At least one reinforcing bracket 222 can be welded on the high-density stainless steel mesh 221. Of course, in order to avoid occupying too much flow channel area of the water liquid, and taking into account the strength of the high-density stainless steel mesh, three sets can be set and The mutual reinforcement bracket 222 is more suitable. In addition, the structure of the inner sleeve 23 can be matched with the setting of the density stainless steel 221, and the structure of the inner sleeve 23 is formed at an end of the high-density non-radial steel mesh 221 to form an end surface 231. The end surface 231 has a flesh thickness, and a through hole 2311 is formed in the end surface 231. Preferably, the through hole is arranged in a concentric arrangement of 10 degrees, so as to have a large water circulation cross-sectional area and support the south density stainless steel mesh. Two characteristics of the strength of 221. In summary, only the method or embodiment of the present invention to solve the problem is described. Track and this _ special Wei Wei _, or new cover.
