Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a material taking mechanism for injection molding machines. Background Art

[0002] Injection molding machine is also known as injection molding machine or injection machine; it is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics; it is divided into vertical, horizontal, and all-electric types; the injection molding machine can heat the plastic, apply high pressure to the molten plastic, so that it is ejected and fills the mold cavity. Since the products produced by the injection molding machine are very heavy, it is also necessary to optimize the injection molding machine for different product material extraction.

[0003] For example, a Chinese utility model patent with announcement number CN212400136U discloses a material-retrieving mechanism for an injection molding machine. Although the above-mentioned prior art can assist in clamping irregular or large workpieces, adapt to the material-retrieving of workpieces of different sizes and shapes, and is reliable in clamping to ensure the production quality of the workpieces, the workpieces molded by injection are all plastic products, and metal clamps are used to clamp and retrieve the workpieces after injection molding. Because the different sizes of plastic products require the clamps to use different forces for clamping, it is not only easy to scratch the surface of the plastic products, but also easy to cause deformation of the plastic products due to failure to adjust the clamp force in time. Therefore, it is necessary to design a material-retrieving mechanism for an injection molding machine that can remove the injection molded products from the injection mold without the use of clamps. Utility Model Content

[0004] In order to solve the technical problem that the plastic products are easily damaged when the injection molding products are taken out by metal clamps, the utility model provides a material taking mechanism for the injection molding machine.

[0005] The utility model is implemented by the following technical scheme: a material taking mechanism for an injection molding machine, comprising an injection molding platform, one side of the injection molding platform is provided with a movable plate for installing an injection mold, one side of the movable plate is provided with an injection molding plate for performing injection molding, both sides of the movable plate are provided with a discharge assembly for removing the injection molded product from the injection mold, both sides of the injection molding plate are provided with an offset assembly for pushing the discharge assembly to shift its position during injection molding production, and one side of each of the discharge assemblies is provided with an auxiliary assembly for assisting the discharge assembly to remove the injection molded product from the injection mold when the movable plate moves.

[0006] Through the above technical solution, after the injection molding of the product, the moving injection mold will cause the unloading component to move as well. After moving to a certain position, the unloading component will remove the product sucked on the injection mold with the assistance of the auxiliary component.

[0007] As a further improvement of the above scheme, sliding grooves are provided on both sides of the movable plate, and the unloading assembly includes a pushing plate slidably arranged inside the sliding groove and a unloading block fixedly installed at one end of the pushing plate, and one side of the unloading block is inclined.

[0008] Through the above technical solution, the push plate allows the unloading block to move, so that the unloading block can separate and remove the plastic product sucked on the injection mold.

[0009] As a further improvement of the above solution, one side of the push plate is provided with two moving grooves penetrating the push plate, and the insides of the two moving grooves are both slidably matched with limiting plates fixedly installed on the inner walls of the sliding grooves.

[0010] Through the above technical solution, the push plate and the limit plate will have a moving range, which can prevent the push plate from moving too much and affecting the injection molding production.

[0011] As a further improvement of the above solution, the offset assembly includes an offset plate fixedly mounted on one side of the injection molding plate and a rotating column rotatably mounted on one side of the offset plate, and one side of the offset plate is arranged in an inclined shape.

[0012] Through the above technical solution, during injection molding production, the gradually closing injection mold will drive the push plate to move together, and the offset plate will cause the discharge block to move, thereby avoiding affecting the closing injection of the injection mold.

[0013] As a further improvement of the above scheme, the auxiliary component includes a fixed block fixedly installed on one side of the movable plate, a fixed column fixedly installed on one side of the fixed block, a sliding sleeve slidingly mounted on one end of the fixed column and a pushing spring mounted on the fixed column, one end of the pushing spring is fixedly mounted on the fixed block and the other end is fixedly mounted on the sliding sleeve, a rolling ball is rotatably mounted on one end of the sliding sleeve, and one side of the rolling ball is in contact with one side of an adjacent pushing plate.

[0014] Through the above technical solution, the spring is pushed to push the sliding sleeve, and the rolling ball is squeezed to push the plate, so that the discharge block can always fit with the injection mold.

[0015] As a further improvement of the above solution, a connecting plate is fixedly installed on one end of the two pushing plates, a return spring is fixedly installed on one side of the two connecting plates, and one end of the two return springs is fixedly installed on the moving plate.

[0016] Through the above technical solution, when the injection molds are separated, the return spring allows the push plate to move along with the injection molds.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a discharge component, an offset component and an auxiliary component. When performing injection molding, a movable plate pushes the injection mold to close and inject. The discharge component moves with the injection mold. When it moves to a certain position, it is pushed and offset by the offset component to avoid affecting the injection molding effect of the injection mold. When the injection molding is completed, the opened injection mold moves backward, and the discharge component also moves backward. When it moves backward to a certain position, the discharge component is stuck and does not move. The auxiliary component is used to insert the discharge block between the product and the mold, and then the product is separated. In this way, the material can be taken out without clamping the plastic product, so as to avoid damage to the surface of the plastic product. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Combination Figure 2 and Figure 3 , sliding grooves are provided on both sides of the movable plate 2, and the unloading assembly includes a pushing plate 401 slidably arranged inside the sliding groove and a unloading block 402 fixedly installed at one end of the pushing plate 401, one side of the unloading block 402 is arranged in an inclined shape, and one side of the pushing plate 401 is provided with two moving grooves that penetrate through itself, and the interiors of the two moving grooves are slidably matched with a limiting plate 7 fixedly installed on the inner wall of the sliding groove. The pushing plate 401 allows the unloading block 402 to move, so that the unloading block 402 can separate and remove the plastic product sucked on the injection mold, and the pushing plate 401 cooperates with the limiting plate 7 to have a moving range, so as to prevent the pushing plate 401 from moving too much and affecting the injection molding production.

[0028] Combination Figure 2 The offset assembly includes an offset plate 501 fixedly mounted on one side of the injection plate 3 and a rotating column 502 rotatably mounted on one side of the offset plate 501. One side of the offset plate 501 is arranged in an inclined shape. During injection molding production, the gradually closing injection mold will drive the pushing plate 401 to move together, and the offset plate 501 will cause the unloading block 402 to move to avoid affecting the closing injection of the injection mold.

[0029] Combination Figure 2-Figure 4 The auxiliary components include a fixed block 601 fixedly installed on one side of the moving plate 2, a fixed column 602 fixedly installed on one side of the fixed block 601, a sliding sleeve 603 slidably mounted on one end of the fixed column 602, and a pushing spring 604 mounted on the fixed column 602. One end of the pushing spring 604 is fixedly installed on the fixed block 601 and the other end is fixedly installed on the sliding sleeve 603. A rolling ball 8 is rotatably installed on one end of the sliding sleeve 603. One side of the rolling ball 8 is in contact with one side of the adjacent pushing plate 401. The pushing spring 604 pushes the sliding sleeve 603 to allow the rolling ball 8 to squeeze the pushing plate 401, so that the unloading block 402 can always be in contact with the injection mold.

[0030] Combination Figure 2 and Figure 3 One end of the two push plates 401 is fixedly installed with a connecting plate 9, one side of the two connecting plates 9 is fixedly installed with a return spring 10, one end of the two return springs 10 is fixedly installed with the movable plate 2, when the injection molds are separated, the return spring 10 will allow the push plate 401 to move with the injection mold.

[0031] The implementation principle of a material taking mechanism for an injection molding machine in the embodiment of the present application is as follows: when performing injection molding production, the moving plate 2 will push one half of the injection mold to close the other half of the injection mold for injection molding. When the mold moves, it will drive the unloading block 402 to move together, and the pushing plate 401 will slide inside the sliding groove. When it moves to a certain position, the unloading block 402 will contact the rotating column 502, so that the rotating column 502 cooperates with the extrusion of the mold to move the unloading block 402 and the pushing plate 401 to avoid affecting the closing effect between the injection molds. When the injection molding is completed, the molds are separated, and the plastic product will be adsorbed on the moving part of the mold, and the backward movement of the mold will allow the unloading block 402 to move. The material block 402 loses the effect of extrusion and deviation, and under the downward pressure of the push spring 604, the sliding sleeve 603 and the rolling ball 8, it returns to one side of the mold, and one side of the unloading block 402 is set in an inclined shape, so the very narrow side will be inserted between the mold and the product, and the mold continues to move backward, and the push plate 401 will continue to move under the pull of the reset spring 10. Finally, the push plate 401 stops moving first, but the mold will continue to move backward. In this way, the push plate 401 will generate a driving force on the plastic product on one side, thereby pushing the plastic product adsorbed on the mold to fall and be collected. This setting can avoid contact with the surface of the plastic product, thereby avoiding damage to the surface of the plastic product due to material removal.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
