Description of the invention: [Technical field to which the invention pertains] The present invention relates to a cleaning device. - [Prior Art] . Injection molding technology refers to the injection of the injection material into the barrel of the injection machine. The heat is transferred to the molten state. Under the push of the screw or plunger of the injection machine, the pouring system of the nozzle and the mold enters. The mold cavity of the mold, the shot material is cooled and hardened (see Knowledge Based Research on Integrated Design ❹ Methods of Hot-Runner Technology for Multi-Cavity Injection Molding 5 Mechatronics and Automation, 2007. ICMA 2007. International Conference on, 5-8 Aug 2007 Page(s): 469 - 474). However, in the normal production of the nozzle for plastic injection molding, due to the accurate measurement parameters of the mold (not shown), it is rare that the plastic is cooled in the nozzle and the nozzle is stuck together. However, when the nozzle is in the test mode, the mold is not determined or the measurement parameters of the mold are inaccurate several times before the production, so the blockage of the plastic in the nozzle often occurs. Generally, a tool such as a screwdriver is used to clear the plastic. When the plastic is loosened to a certain extent, the plastic can be completely detached from the nozzle. However, during the process of loosening the plastic, the mouth of the nozzle is easily damaged by the screwdriver. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a cleaning device for protecting a nozzle opening of a plastic injection molding from damage. 201006653 A cleaning device for removing (4) a plastic mold in a nozzle of a molding die, the injection molding die having a fixed side skirting plate, a positioning ring fixed on the fixed side device plate, and a nozzle. The fixed side device plate has a first receiving hole coaxial with the material level ring, and the first receiving hole is used for receiving the filling nozzle. The filling nozzle includes a filling nozzle coaxial with the first receiving hole. The mouth π (four) Guanyin Qiangji m green removing device comprises: a positioning shank and an impact member received in the positioning ring and fixed relative to the positioning ring, and the positioning seat is provided with a (four) positioning seat for accommodating the far a second receiving hole of the impacting member, the second receiving hole is coaxial with the positioning ring, so that the impact member received therein passes through the positioning seat and impacts the plastic in a direction perpendicular to the filling opening. Compared with the prior art, the cleaning device guides the impact direction of the impact member by the positioning ring and the positioning seat, so that the impact member can only impact the plastic in a direction perpendicular to the mouth of the nozzle, thereby making the nozzle The mouth is protected from damage during the impact process. • [Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings. s 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The injection molding die 20 further has a fixed side device plate 26 and a positioning ring 28 fixedly mounted on the fixed side device plate % by screws 280. In the present embodiment, the center of the positioning ring 28 is a circular through hole 282. Of course, the center of the positioning % 28 may also be a truncated-shaped through hole, that is, the truncated-shaped through-hole flat 8 201006653. The cross-section of the central axis of the positioning ring 28 is trapezoidal. The fixed side device plate 26 has a first receiving hole 262 for receiving the filling nozzle 22. The central axis of the first receiving hole 262 coincides with the center axis of the positioning ring 28 such that the positioning ring 28 and the central axis of the nozzle 22 are in the same line. The nozzle 22 includes a mouthpiece 222 and a sprue 224 that is connected to the mouth 222 and that receives the plastic 24. The mouth opening 222 is located at the end of the nozzle 22 adjacent to the positioning ring 28 and is coaxial with the positioning ring 28. ® The cleaning device 10 includes a positioning seat 12 and an impact member 14. The positioning seat 12 is shaped as a two-stage cylinder, and the diameter of the end portion in contact with the positioning ring 28 is equal to the diameter of the positioning ring 28 to fix the positioning seat 12 relative to the positioning ring 28. The positioning seat 12 is provided with a second receiving hole 122 for receiving the impact member 14 through the positioning seat 12 in the central axis direction of the positioning seat 12. The central axis of the second receiving hole 122 coincides with the central axis of the positioning ring 28, so that the impact member 14 received therein passes through the positioning seat 12 and impacts the plastic 24 in the direction of the vertical filling opening 222. The second receiving hole 122 is a counterbore having a first hole 1222 having a larger diameter and a second hole 1224 having a smaller diameter, and the first hole 1222 is adjacent to the filling nozzle 22. The impacting member 14 has an impact bar 142, a pin 144 fixed to the end of the impact bar 142 near the nozzle 22, a shock block 146 movably disposed through the impact bar 142, and a fixed portion The impact bar 142 is away from the end of the nozzle 22, and the stopper for preventing the impact block 146 from being detached from the impact bar 148 ° 9 201006653. The impact bar 142 is a three-stage cylinder, from the proximity of the nozzle 22 The side has a first segment 1422, a second segment 1424, and a third segment 1426 in sequence. The diameters of the first segment 1422, the second segment 1424, and the third segment 1426 are sequentially decreased, and an impact is formed from the contact of the second segment 1424 with the third segment 1426. A first fixing unit 1429 extending along a central axis of the first segment 1422 is disposed on the end surface of the first segment 1422 facing the nozzle 22, and the diameter of the first segment 1422 is equal to the second receiving hole 122. The diameter of the first hole 1224 is such that the impact bar 142 can move the positioning seat 12 away from the positioning ring 28 after the cleaning of the plastic 24 is completed. In this embodiment, the first fixing unit 1429 is a screw column (ie, the outer surface of the cylinder has a thread). Of course, the first fixing unit 1429 can also be a fixing member such as a screw hole, a through hole, a cylinder, a quadrangular prism, and a pentagonal prism. Of course, the number of the first fixing units 1429 may also be two or three or four or more. ^ The diameter of the second segment 1424 is less than or equal to the diameter of the second hole 1224, and the length of the second segment 1426 in a direction parallel to the central axis of the positioning ring 28 is greater than the second hole 1224 is parallel to the positioning ring. The length of the central axis direction of 28 is such that the impact bar 142 can pass through the positioning block 12. The shot 144 can be made of a material such as copper, iron, or nickel. Preferably, in the present embodiment, the pin 144 is made of a copper material. The nozzle 22 is generally made of a stainless steel material and has a relatively high hardness. Therefore, the copper needle 144 having a relatively soft hardness is used for impact. Even if the needle 144 hits the nozzle opening 222, the nozzle is not applied to the nozzle. Port 222 causes damage. 201006653 The needle 144 has a cylindrical fixing portion 1442, a cylindrical head 1444 opposite to the fixing portion 1442 and having a diameter smaller than the diameter of the fixing portion 1442, and a connection between the fixing portion 1442 and the head 1444. Department • 1446. Wherein, the striker 1444 can enter the sprue 224 during the impact process; • contact with the plastic 24. A second fixing unit 1445 for use with the first fixing unit 1429 is disposed on an end surface of the fixing portion 1442 opposite to the impact bar 142, so that the pin 144 is fixedly coupled to the impact bar 142. In this embodiment, the second fixing unit 1445 is a screw hole. Of course, the second fixing unit 1445 can also be a fixing member used in conjunction with the first fixing unit 1429, such as a screw post, a through hole, a cylinder, a quadrangular prism, a pentagonal ridge, and the like. The connecting portion 1446 is shaped as a truncated cone having a first end 1447 coupled to the fixed portion 1442 and a second end 1448 opposite the first end 1447 and coupled to the striking head 1444. The first end 1447 has the same diameter as the fixed portion 1442. The diameter of the second end 1448 is less than the diameter of the fixed portion 1442 and greater than or equal to the diameter of the striker 1444. Since the shape of the connecting portion 1446 is a truncated cone, the possibility that the firing pin 144 is in contact with the filling port 222 is reduced, thereby reducing the possibility that the firing pin 144 damages the filling opening 222. The impact block 146 is a cylindrical structure having a third hole 1462 extending through the impact block 146 and having the same diameter as the third section 1426 of the impact rod 142 to make the impact block 146 movable. The third segment 1426 of the impact bar 142 is worn. The impact block 146 is used to impact the impact surface 1428 to drive the impact bar 142 and the pin 144 to impact the plastic 24. Of course, the impact bar 142 can also be a two-stage cylinder. π 201006653 Of course, the shot; [44 $ shape iit · * · and other shapes. The scorpion shape may also be a cone shape or a spheroid shape. The cleaning device iq provided in the first embodiment of the present invention, by means of the yoke 12 and guiding the impact member 14 garment 28, can only be perpendicular to the spigot opening 222 In the square direction, the impactor 4 is also protected from the plastic I, so that the cleaning device 10 does not need to remove the nozzle 22 from the injection molding die 2, and you and the lesser 4 have fewer processes. Shortened the time. As shown in the figure, the second embodiment of the present invention provides 13l〇a, which is identical to the π removing device 9, ^^ of the cleaning device 1G (4), and has a positioning seat 12a and an impact member housed in the positioning ring. 14a, the positioning seat ua is provided with two positioning holes for receiving the second receiving hole 122a of the impact member W, the central axis of the second-receiving hole 122a and the mosquito ring - "Center weight: stationed to accommodate The impact member 14a is inserted into the (four) seat and impacts the plastic (10) in the direction of the nozzle 222a. The difference is that the second receiving hole 122a of the positioning seat is a through hole. The impact member is a diameter. The impact rod having the same diameter as the second receiving hole 122a of the soil, and the end portion of the impact member 14a adjacent to the mouth opening 222a is semi-ellipsoidal.
