Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding machine for plastic products. Background Art

[0002] Plastic injection molding is a common process for manufacturing plastic products and is widely used in various industrial fields, such as automobiles, household appliances, packaging, toys, electronic products, etc. Its basic principle is to heat plastic raw materials (usually granular resins) to a molten state and then inject them into a mold under high pressure. After cooling and solidifying, plastic products with the required shape are obtained.

[0003] An injection molding machine with two injection ports disclosed in Chinese Patent CN220548604U includes a bottom plate and an injection molding machine body. The injection molding machine body is fixedly arranged on the top of the bottom plate. One side of the injection molding machine body is communicated with a double injection pipe. A shaping mechanism is arranged between the double injection pipe and the bottom plate. A placement rack is elastically slidably arranged on the top of the bottom plate. A containing frame is placed inside the placement rack. When the containing frame sifts the stacking space, the injection molding machine with two injection ports can be linked with a cooling mechanism to further cool the residual heat of the products inside the containing frame, so as to facilitate subsequent operation by operators. However, in actual use, this patent still has certain deficiencies. The device injects molten plastic into the mold through a pipeline. After the plastic cools and hardens, it easily adheres to the inner wall of the pipeline, causing pipeline blockage and affecting the discharge. Moreover, the internal space of the pipeline is narrow and long, and it is also troublesome to clean. Summary of the Utility Model

[0004] In order to overcome the above-mentioned disadvantages of the prior art, the utility model provides an injection molding machine for plastic products that is easy to clean.

[0005] The technical implementation scheme of the utility model is as follows: an injection molding machine for plastic products includes a workbench, an injection mold, an electric guide rail, a sliding table, a compression plate, a support frame, a support plate, a guide rod, a sliding sleeve, a box body and a baffle. The injection mold is arranged inside the workbench. Four electric guide rails are symmetrically installed on the top of the workbench. A sliding table is slidably arranged among the four electric guide rails. A compression plate is arranged on the sliding table. A support frame is fixedly arranged on the left side of the workbench. Two support plates are fixedly arranged on the support frame. Guide rods are fixedly arranged between the tops of the two support plates and the support frame. Sliding sleeves are slidably arranged on the two guide rods. A box body is fixedly arranged between the two sliding sleeves. A baffle is slidably arranged at the bottom of the box body.

[0022] First of all, it should be pointed out that in different described implementation modes, the same components are provided with the same reference numerals in the drawings or the same component names. Among them, the disclosed content included in the entire specification can be meaningfully applied to the same components with the same reference numerals in the drawings or the same component names. The position descriptions selected in the specification, such as up, down, lateral, etc., also refer to the directly described and shown drawings and are meaningfully applied to the new positions when the positions change.

[0023] As Figures 1 - 5 shown, an injection molding machine for plastic products provided by an embodiment of the present invention includes a workbench 1, an injection mold 2, an electric guide rail 3, a slide table 4, a compression plate 41, a support frame 5, a support plate 51, a guide rod 6, a slide sleeve 61, a box body 7 and a baffle plate 10. The inside of the workbench 1 is set as a hollow structure, and the injection mold 2 is detachably installed inside it through bolts. The injection mold 2 can be replaced according to the products to be produced. Four electric guide rails 3 are symmetrically installed on the top of the workbench 1. A slide table 4 is slidably arranged among the four electric guide rails 3. A compression plate 41 adapted to the injection mold 2 is arranged on the slide table 4, and the compression plate 41 is also detachably installed. By controlling the slide table 4 to descend by using the electric guide rail 3, the compression plate 41 can be made to cooperate downward with the compression plate 41, so that the molten plastic is shaped. A support frame 5 is fixedly arranged on the left side wall of the workbench 1. Two support plates 51 are welded on the left side of the support frame 5. Guide rods 6 are fixedly arranged between the two support plates 51 and the top of the right side of the support frame 5. Slide sleeves 61 are slidably arranged on the two guide rods 6. A box body 7 is fixedly connected between the two slide sleeves 61. Molten plastic can be stored in the box body 7. A baffle plate 10 is slidably arranged at the bottom of the box body 7. By moving the whole box body 7 to the right above the injection mold 2 and then moving the baffle plate 10 away, the molten plastic inside it can be injected into the injection mold 2.

[0024] As Figure 1 and Figure 5As shown, in the embodiment of the present utility model, it further includes a cover plate 8 and a scraping frame 9. A cover plate 8 is provided at the top of the box body 7. Covering the cover plate 8 can prevent sundries from mixing into the molten plastic in the box body 7. And a scraping frame 9 is fixedly provided at the bottom of the cover plate 8. The scraping frame 9 fits against the inner side wall of the box body 7. When the cover plate 8 is lifted upward, the scraping frame 9 slides along the inner side wall of the box body 7 and scrapes off the plastic adhered to the inner side wall of the box body 7, avoiding the plastic from hardening and sticking to the inner side wall of the box body 7, making it more labor-saving to clean the box body 7 later.

[0025] As Figure 3 and Figure 4 As shown, in the embodiment of the present utility model, it further includes a first elastic member 11, a connecting block 12, a contact block 13 and a second elastic member 14. A first elastic member 11 is provided between the baffle 10 and the box body 7. The first elastic member 11 is a spring. A connecting block 12 is fixedly provided at the bottom of the baffle 10. A contact block 13 is slidably provided on the workbench 1. A second elastic member 14 is provided between the contact block 13 and the workbench 1. The second elastic member 14 is a spring. When the box body 7 slides to the right, the connecting block 12 can contact the contact block 13 and be blocked by the contact block 13, so that the baffle 10 can slide open by itself.

[0026] In the embodiment of the present utility model, first, molten plastic needs to be injected into the box body 7, and then the cover plate 8 is covered. Subsequently, 1 pushes the box body 7 and the sliding sleeve 61 to slide to the right along the guide rod 6. During this process, the connecting block 12 will fit against the contact block 13. Then, as the box body 7 continues to move to the right, the connecting block 12 is blocked by the contact block 13, causing the baffle 10 to slide open, and the first elastic member 11 compresses and stores energy. The molten plastic in the box body 7 also falls into the injection mold 2 accordingly. Then, the box body 7 is pushed back to its original position, and the baffle 10 resets under the action of the first elastic member 11, closing the bottom of the box body 7 again. Then, the electric guide rail 3 is started, driving the slide table 4 to move downward, and the compression plate 41 also descends and presses into the injection mold 2, enabling the molten plastic inside the injection mold 2 to be shaped. And when the compression plate 41 contacts the contact block 13, it will press the contact block 13 into the workbench 1 to avoid it from hindering the injection process.

[0027] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present utility model. Therefore, the scope of the present utility model should be limited only by the appended claims.
