Description

Technical Field

[0001] The utility model relates to the field of injection molding devices, and in particular mainly to an anti-blocking injection molding device. Background Art

[0002] The injection molding device is a device used for injection molding, usually used to manufacture plastic products. It consists of an injection molding machine, a mold and auxiliary equipment. The injection molding machine is the core component of the injection molding device. It injects plastic particles or granular melt into the mold by heating and pressurizing, so that it cools and hardens in the mold to form a product of the desired shape.

[0003] When the existing injection molding device is in use, when the raw materials are processed and then transported to the mold through the pipe body, they may clump and sink to the bottom, resulting in poor final product effect and possible clogging of the injection molding device. During the injection molding, several finished products are pre-tested first. During the mixing process, the raw materials in the connecting pipe may also clump, resulting in inaccurate performance of the pre-tested products. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an anti-clogging injection molding device.

When the reciprocating cylinder is started, the output shaft of the reciprocating cylinder will reciprocate up and down, thereby driving the rotating plate to reciprocate up and down, and the bottom surface of the rotating plate is fixedly connected to an L-shaped rod, and the end of the L-shaped rod away from the rotating plate penetrates and is fixedly connected to the rotating rod, because the L-shaped rod penetrates the arc-shaped slide column, so that the L-shaped rod drives the rotating rod to rotate, and the inner bottom surface of the cavity is fixedly connected to the arc-shaped slide column;

[0007] An arc-shaped connecting plate, wherein the side of the arc-shaped connecting plate close to the inner wall of the lower tube body is fixedly connected to the inner wall of the lower tube body, the side of the arc-shaped connecting plate away from the inner wall of the lower tube body is fixedly connected to a fixing column, the rotating rod passes through and is fixedly connected to the connecting column, the side of the connecting column is fixedly connected to an arc-shaped transmission plate, and the rotating rod will drive the connecting column to rotate when it rotates, and the connecting column will drive the arc-shaped transmission plate to rotate when it is driven to rotate by the rotating rod, so that the viscous injection molding material is stirred to a certain extent when passing through the lower tube body.

[0008] Preferably, the lower tube body is penetrated by and fixedly connected to the heating rod, and a filter screen is fixedly connected to the inner wall of the lower tube body.

[0009] Preferably, the number of the arc-shaped connecting plates is three groups, and the three groups of arc-shaped connecting plates are respectively arranged in a circular array with the center line of the fixing column as the axis.

[0010] Preferably, the bottom end of the rotating rod penetrates the filter screen, and when the arc-shaped transmission plate moves to the bottom, it scrapes the top surface of the filter screen.

[0011] Preferably, the upper tube body is penetrated by the feed pipe and fixedly connected.

[0012] Preferably, the middle portion of the rotating rod passes through the upper tube body.

[0013] Preferably, the number of the arc-shaped transmission plates is six groups, and the six groups of arc-shaped transmission plates are respectively arranged in a circular array with the center line of the connecting column as the axis. At the same time, since three groups of arc-shaped connecting plates are arranged, the stirring of the arc-shaped transmission plates can make the injection molding raw materials move downward in a vortex shape, thereby preventing some injection molding raw materials from sinking to the bottom and agglomerating when stored for a long time, causing blockage of the upper tube body or the lower tube body.

[0014] Preferably, the bottom end of the L-shaped rod passes through the arc-shaped slide groove column and is threadedly connected.

[0015] The beneficial effects of this application are:

[0016] 1. In the anti-clogging injection molding device, the rotating rod will drive the connecting column to rotate when it rotates, and the connecting column will drive the arc-shaped transmission plate to rotate when it is driven by the rotating rod, so that the viscous injection molding material can be stirred to a certain extent when passing through the lower tube body. At the same time, due to the provision of three sets of arc-shaped connecting plates, the stirring of the arc-shaped transmission plates makes the injection molding material move downward in a vortex shape, and finally discharge the material through the discharge pipe, thereby preventing some injection molding materials from sinking to the bottom and agglomerating when stored for a long time, causing blockage of the upper tube body or the lower tube body.

[0017] 2. The anti-clogging injection molding device will drive the arc-shaped transmission plate to move up and down and rotate when the rotating rod rotates and moves up and down. At the same time, when the arc-shaped transmission plate moves to the bottom, it will scrape the top surface of the filter screen to make the raw materials passing through the filter screen more delicate, and start the heating rod to prevent some injection molding materials from solidifying and better pass through the injection molding device.

[0028] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0029] Embodiment 1:

[0030] Reference Figures 1 to 5 The anti-clogging injection molding device in the utility model includes an upper tube body 1 and a lower tube body 3. The bottom end of the lower tube body 3 is fixedly connected with a discharge pipe 4. A control part 2 is arranged inside the upper tube body 1. The control part 2 includes: a cavity 21, a reciprocating cylinder 22, a rotating plate 23, an L-shaped rod 24, a rotating rod 25, an arc-shaped slide column 26, a connecting plate 27, a fixed column 28, a connecting column 29, an arc-shaped transmission plate 210, a filter screen 211, and a heating rod 212.

[0031] The cavity 21 is opened inside the upper tube body 1, and the top surface of the cavity 21 is fixedly connected to a reciprocating cylinder 22, and the bottom end of the reciprocating cylinder 22 is rotatably connected to a rotating plate 23, and the feed pipe 5 is connected to the injection molding equipment, so that the injection molding raw material enters the upper tube body 1 through the feed pipe 5, and the reciprocating cylinder 22 is started. When the reciprocating cylinder 22 is started, the output shaft of the reciprocating cylinder 22 will reciprocate up and down, thereby driving the rotating plate 23 to reciprocate up and down, and the bottom surface of the rotating plate 23 is fixedly connected to an L-shaped rod 24, and the end of the L-shaped rod 24 away from the rotating plate 23 penetrates and is fixedly connected to a rotating rod 25. Since the L-shaped rod 24 penetrates the arc-shaped slide groove column 26, the arc-shaped slide groove column 26 limits the L-shaped rod 24, so that the L-shaped rod 24 will move downward. The L-shaped rod 24 rotates along the arc-shaped chute column 26, so that the L-shaped rod 24 drives the rotating rod 25 to rotate. The inner bottom surface of the cavity 21 is fixedly connected with the arc-shaped chute column 26. The side of the arc-shaped connecting plate 27 close to the inner wall of the lower tube body 3 is fixedly connected with the inner wall of the lower tube body 3. The side of the arc-shaped connecting plate 27 away from the inner wall of the lower tube body 3 is fixedly connected with the fixing column 28. The rotating rod 25 penetrates and is fixedly connected with the connecting column 29. The side of the connecting column 29 is fixedly connected with the arc-shaped transmission plate 210. When the rotating rod 25 rotates, it drives the connecting column 29 to rotate. When the connecting column 29 is driven to rotate by the rotating rod 25, it drives the arc-shaped transmission plate 210 to rotate, so that the viscous injection molding raw material is stirred to a certain extent when passing through the lower tube body 3. The lower tube body 3 is penetrated and fixedly connected by the heating rod 212, and the inner wall of the lower tube body 3 is fixedly connected with the filter screen 211. There are three groups of arc-shaped connecting plates 27, and the three groups of arc-shaped connecting plates 27 are arranged in a circular array with the center line of the fixed column 28 as the axis. The bottom end of the rotating rod 25 penetrates the filter screen 211. At the same time, when the arc-shaped transmission plate 210 moves to the bottom, it will scrape the top surface of the filter screen 211 to make the raw materials passing through the filter screen 211 more delicate, and start the heating rod 212 to prevent some injection molding raw materials from solidifying and pass through the injection molding device better. The upper tube body 1 is penetrated and fixedly connected by the feed pipe 5. The middle part of the rotating rod 25 penetrates the upper tube body 1. Since the filter screen 211 is fixedly connected to the inner wall of the lower tube body 3, when the rotating rod 25 rotates and moves up and down, it will drive the arc-shaped transmission plate 210 to move up and down and rotate. There are six groups of arc-shaped transmission plates 210, and the six groups of arc-shaped transmission plates 210 are arranged in a circular array with the center line of the connecting column 29 as the axis. At the same time, due to the arrangement of three groups of arc-shaped connecting plates 27, the stirring of the arc-shaped transmission plates 210 causes the injection molding raw materials to move downward in a vortex shape, and finally discharge through the discharge pipe 4, thereby preventing some injection molding raw materials from sinking to the bottom and agglomerating when stored for a long time, causing blockage of the upper tube body 1 or the lower tube body 3. The bottom end of the L-shaped rod 24 passes through the arc-shaped slide column 26 and is threadedly connected.

[0032] In summary, the feed pipe 5 is connected to the injection molding equipment, so that the injection molding raw material enters the upper tube body 1 through the feed pipe 5, and the reciprocating cylinder 22 is started. When the reciprocating cylinder 22 is started, the output shaft of the reciprocating cylinder 22 will reciprocate up and down, thereby driving the rotating plate 23 to reciprocate up and down, and when the rotating plate 23 reciprocates up and down, it will drive the L-shaped rod 24 to reciprocate up and down. Since the L-shaped rod 24 passes through the arc-shaped slide groove column 26, the arc-shaped slide groove column 26 limits the L-shaped rod 24, so that the L-shaped rod 24 will rotate along the arc-shaped slide groove column 26 when moving downward, thereby The L-shaped rod 24 drives the rotating rod 25 to rotate, and the rotating rod 25 drives the connecting column 29 to rotate. When the connecting column 29 is driven to rotate by the rotating rod 25, it drives the arc-shaped transmission plate 210 to rotate, so that the viscous injection molding material is stirred to a certain extent when passing through the lower tube 3. At the same time, due to the provision of three groups of arc-shaped connecting plates 27, the stirring of the arc-shaped transmission plate 210 causes the injection molding material to move downward in a vortex shape, and finally be discharged through the discharge pipe 4, thereby preventing some injection molding materials from sinking to the bottom and agglomerating when stored for a long time, causing blockage of the upper tube 1 or the lower tube 3.

At the same time, when the arc-shaped transmission plate 210 moves to the bottom, it will scrape the top surface of the filter screen 211 to make the raw materials passing through the filter screen 211 more delicate, and start the heating rod 212 to prevent some injection molding raw materials from solidifying and better pass through the injection molding device.
