Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to an anti-clogging structure for injection molding equipment. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. The working principle of an injection molding machine is similar to that of a syringe; it uses the thrust of a screw (or plunger) to inject pre-plasticized molten plastic (i.e., viscous flow state) into a closed mold cavity, where it solidifies and sets to obtain the finished product.

[0003] In actual injection molding production, during the melting process of the sol in the injection molding machine, large particles such as incompletely melted resin particles and carbonized substances are easily generated. Because the discharge hole of the injection molding head is small, these large particles can easily cause blockage of the injection molding head when they follow the sol through the discharge, thus affecting the working efficiency of the injection molding machine. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-clogging structure for injection molding equipment to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is an anti-clogging structure for injection molding equipment, comprising:

[0006] An anti-clogging shell is provided with a filter screen fixedly installed on the inner wall of the anti-clogging shell, a fixing frame is fixedly installed on the side of the top of the anti-clogging shell, and a connecting frame is fixedly installed on one side of the fixing frame.

[0007] The cleaning component includes a motor, one side of which is fixedly mounted on one side of a connecting frame. A rotating shaft is fixedly mounted on the output end of the motor. A connecting rod is fixedly mounted on one end of the rotating shaft. A connecting shaft is fixedly mounted on the bottom end of one side of the connecting rod. A fixing frame is slidably mounted on the outer wall of the connecting shaft. A vertical rod is fixedly mounted on the bottom end of the fixing frame. A first scraper is fixedly mounted on the bottom end of the vertical rod. One side of the first scraper is attached to one side of the filter screen.

[0008] Furthermore, a limiting block is fixedly provided at one end of the connecting shaft, and the diameter of the limiting block is greater than the height of the inner wall of the fixed frame.

[0009] Furthermore, the outer walls of the rotating shaft extend through one side of the fixing frame and the connecting frame, respectively.

[0010] Furthermore, a sealing frame is embedded at the top of the anti-clogging shell, and the outer wall of the vertical rod penetrates the inner wall of the sealing frame.

[0011] Furthermore, the length of the connecting rod is adapted to half the height of the filter screen.

[0012] Furthermore, a sealing cover is fitted into the inner bottom of the anti-clogging shell, and two locking screws are threaded through the bottom of the sealing cover, with the top of the locking screws threadedly connected to the bottom of the anti-clogging shell.

[0013] Furthermore, it also includes auxiliary components, the auxiliary components including a first transmission gear, the inner wall of the first transmission gear being fixedly disposed on the outer wall of the rotating shaft, a second transmission gear being meshed at the bottom end of the first transmission gear, a connecting shell being fixedly disposed on the inner wall of the second transmission gear, and a second scraper being fixedly disposed on the inner wall of the connecting shell.

[0015] This utility model has the following beneficial effects:

[0016] This invention features a filter screen and a first scraper. A motor drives a first connecting rod to rotate via a shaft. The rotation of the first connecting rod, in turn, causes a fixed frame to move upwards and reciprocally via the connecting shaft. This, in turn, causes the first scraper to move upwards and reciprocally via a vertical rod. The filter screen effectively removes impurities from the molten plastic, preventing blockages in the injection molding head and thus maintaining the injection molding machine's efficiency. Simultaneously, the first scraper removes impurities from the filter screen, preventing their accumulation and improving the overall anti-clogging effect. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is an anti-clogging structure for injection molding equipment, comprising:

[0027] The anti-clogging shell 11 has a filter screen 111 fixedly installed on its inner wall, a fixing bracket 12 fixedly installed on the side of the top of the anti-clogging shell 11, and a connecting bracket 13 fixedly installed on one side of the fixing bracket 12.

[0028] The anti-clogging shell 11 is installed between the feed pipe of the injection molding machine and the injection head. The filter screen 111 is made of metal (such as stainless steel) and is used to filter impurities in the molten plastic (such as metal scraps, carbon deposits, and incompletely molten resin particles) to prevent the injection head from clogging.

[0029] The cleaning component includes a motor 21. One side of the motor 21 is fixedly mounted on one side of the connecting frame 13. A rotating shaft 22 is fixedly mounted on the output end of the motor 21. A connecting rod 23 is fixedly mounted on one end of the rotating shaft 22. A connecting shaft 24 is fixedly mounted on the bottom end of one side of the connecting rod 23. A fixing frame 25 is slidably mounted on the outer wall of the connecting shaft 24. A vertical rod 26 is fixedly mounted on the bottom end of the fixing frame 25. A first scraper 27 is fixedly mounted on the bottom end of the vertical rod 26. One side of the first scraper 27 is attached to one side of the filter screen 111.

[0030] The motor 21 is used to provide the driving force required for the first scraper 27 to move up and down. During the rotation of the connecting rod 23 to 180 degrees, it drives the fixed frame 25 to move upward through the connecting shaft 24. During the rotation of the connecting rod 23 to 360 degrees, it drives the fixed frame 25 to move downward through the connecting shaft 24. The length of the first scraper 27 is adapted to the length of the filter screen 111.

[0031] A limiting block 28 is fixedly provided at one end of the connecting shaft 24, and the diameter of the limiting block 28 is greater than the height of the inner wall of the fixed frame 25;

[0032] Limiting block 28 is used to assist in limiting the movement of fixed frame 25.

[0033] The outer walls of the rotating shaft 22 extend through one side of the fixing frame 12 and the connecting frame 13, respectively;

[0034] The rotating shaft 22 is rotatably engaged with the fixed frame 12 and the connecting frame 13 respectively. The fixed frame 12 and the connecting frame 13 connect and rotate it, thereby improving the overall stability of the rotating shaft 22 during rotation.

[0035] A sealing frame 14 is embedded at the top of the anti-clogging shell 11, and the outer wall of the vertical rod 26 penetrates the inner wall of the sealing frame 14;

[0036] The vertical rod 26 slides in conjunction with the sealing frame 14.

[0037] The length of the connecting rod 23 is adapted to half the height of the filter screen 111;

[0038] In this way, during the rotation of the connecting rod 23, the reciprocating stroke of the first scraper 27 is adapted to the height of the filter screen 111.

[0039] The bottom of the anti-clogging shell 11 is fitted with a sealing cover 112, and the bottom of the sealing cover 112 is provided with two locking screws 113, and the top of the locking screws 113 is threadedly connected to the bottom of the anti-clogging shell 11.

[0040] The locking screw 113 is used to limit and fix the sealing cover 112. The bottom end of the anti-blocking shell 11 has two screw holes that are compatible with the locking screw 113.

[0041] Working principle: When molten plastic enters the injection molding head through the filter screen 111, impurities in the molten plastic are filtered out by the filter screen 111. At the same time, the motor 21 is turned on, which drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the connecting rod 23 to rotate. The rotation of the connecting rod 23 drives the fixed frame 25 to move upward and reciprocally through the connecting shaft 24. The up and down reciprocating movement of the fixed frame 25 drives the first scraper 27 to move upward and reciprocatingly through the vertical rod 26. The filter screen 111 can filter impurities in the molten plastic, avoiding blockage of the injection molding head and thus not affecting the working efficiency of the injection molding machine. At the same time, the first scraper 27 can scrape off impurities on the filter screen 111, preventing impurities from accumulating and affecting the filtration of the filter screen 111, thereby improving the overall anti-clogging effect.

[0042] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0043] The auxiliary component includes a first transmission gear 31, the inner wall of which is fixedly disposed on the outer wall of the rotating shaft 22, a second transmission gear 32 meshing at the bottom end of the first transmission gear 31, a connecting shell 33 fixedly disposed on the inner wall of the second transmission gear 32, and a second scraper 34 fixedly disposed on the inner wall of the connecting shell 33.

[0044] The inner diameter of the connecting shell 33 is adapted to the inner diameter of the injection molding head, and the material can be scraped from the inner diameter of the injection molding head by the second scraper 34.

[0045] One end of the connecting shell 33 is rotatably connected to one side of the anti-blocking shell 11;

[0046] The other end of the connecting shell 33 is rotatably connected to one end of the injection molding machine head, and the other side of the anti-blocking shell 11 is fixedly connected to the end of the injection molding machine's feed pipe.

[0047] Working principle: During the rotation of the rotating shaft 22, which drives the first scraper 27 to move up and down, the rotation of the rotating shaft 22 also drives the first transmission gear 31 to rotate. The rotation of the first transmission gear 31 drives the second transmission gear 32 to rotate, which in turn drives the second scraper 34 to rotate through the connecting shell 33. This causes the second scraper 34 to scrape the material on the inner wall of the injection molding head, thus preventing the molten plastic on the inner wall of the injection molding head from clogging after cooling, thereby further improving the overall anti-clogging effect of the device.
