Description

Technical Field

[0001] This utility model relates to the field of plastic product processing and molding technology, specifically a molding device suitable for processing plastic products with complex structures. Background Technology

[0002] In the field of plastic product processing, innovation and development in various industries have led to a continuous increase in demand for complex plastic products. From miniaturized parts for precision electronic devices to complex styling components for large automotive interiors, these technologies pose stringent challenges to molding processes. Deep cavity injection molding, as one of the key technologies for processing such complex plastic products, plays an important role.

[0003] However, traditional plastic product processing and molding equipment has revealed many drawbacks in deep cavity injection molding. Due to the special structure of the deep cavity, the flow path of the casting material is long and complex during the injection process. When the front end of the material reaches the end of the deep cavity, the flow rate is easily reduced due to pressure decay and cooling, resulting in a speed difference with the subsequently injected material, which in turn causes uneven casting. As the casting material advances, it is very easy to be trapped and form air bubbles, which affects the structural strength and mechanical properties of the plastic product. Therefore, there is an urgent need for a molding device suitable for processing plastic products with complex structures to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a molding device suitable for processing complex plastic products, in order to solve the problem mentioned in the background art that traditional plastic product processing molding devices may have uneven pouring and thus air bubbles during deep cavity injection molding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a molding device suitable for processing plastic products with complex structures, comprising a main mold, wherein the main mold has a casting cavity inside, and a floating component is provided on the inner wall of the casting cavity;

[0006] The floating component includes a floating plate that is slidably connected to the inner wall of the casting cavity. A connecting frame is fixedly connected to the top surface of the main mold. The connecting frame is movably sleeved with the inner wall of the casting cavity. A sliding hole is opened on the top surface of the connecting frame. A fixed column is slidably connected to the inner wall of the sliding hole. The fixed column is fixedly connected to the inner wall of the main mold.

[0007] Preferably, the top surface of the floating plate is provided with a plurality of fixing holes, and the inner wall of the fixing holes is fixedly connected with a connector.

[0008] Preferably, two sealing sleeves are fixedly connected to the surface of the floating plate, and the inner wall of the sealing sleeve is in contact with the inner wall of the casting cavity.

[0009] Preferably, the surface of the fixed column is provided with multiple sliding grooves, and the inner wall of the sliding hole is fixedly connected with multiple sliding blocks, which are slidably connected to the inner wall of the sliding groove.

[0010] Preferably, a positioning frame is rotatably connected to the surface of the fixed column, and the positioning frame is fixedly connected to the inner wall of the main mold.

[0011] Preferably, the main body mold is composed of an upper mold and a lower mold, the bottom surface of the upper mold is provided with an embedding groove, and the lower mold abuts against the inner wall of the embedding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] With the floating component in place, when the injection molding feed pipe starts feeding material, the injection molding raw material is directly conveyed to the bottom surface of the floating plate through the connector. As the raw material on the bottom surface of the floating plate increases and continues to be conveyed, the raw materials are squeezed against each other, which pushes the floating plate to float upwards first, and then continues to convey material until the floating plate is pushed to the top surface of the inside of the gating cavity. When the raw material on the bottom surface of the floating plate squeezes against each other, the raw materials are in full contact with each other, thereby reducing the probability of air bubbles appearing due to uneven filling of raw materials during deep cavity injection molding.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a molding device suitable for processing complex plastic products, including a main mold 1. The main mold 1 has a casting cavity 2 inside. A floating component 3 is provided on the inner wall of the casting cavity 2. The floating component 3 includes a floating plate 301, which is slidably connected to the inner wall of the casting cavity 2. A connecting frame 302 is fixedly connected to the top surface of the main mold 1. The connecting frame 302 is movably sleeved with the inner wall of the casting cavity 2. A sliding hole 303 is opened on the top surface of the connecting frame 302. A fixing post 304 is slidably connected to the inner wall of the sliding hole 303. The fixing post 304 is connected to the main mold 1. The inner wall is fixedly connected. Through the floating component 3, the floating plate 301 stays on the bottom surface of the inside of the casting cavity 2 when it is not being injected. The injection material is then transported to the bottom surface of the floating plate 301. As the material on the bottom surface of the floating plate 301 increases and is continuously transported, the material is squeezed against each other, which pushes the floating plate 301 to float upward first, and then continues to transport material until the floating plate 301 is pushed to the top surface of the inside of the casting cavity 2. When the material on the bottom surface of the floating plate 301 is squeezed against each other, the material is fully in contact with the material, thereby reducing the probability of air bubbles appearing after uneven material filling during deep cavity injection.

[0021] Furthermore, the top surface of the floating plate 301 is provided with multiple fixing holes 305, and the inner wall of the fixing holes 305 is fixedly connected with connectors 306. The multiple connectors 306 facilitate the comprehensive pouring of the bottom surface of the floating plate 301 at multiple locations, thereby improving the uniformity of the pouring.

[0022] Furthermore, two sealing sleeves 307 are fixedly connected to the surface of the floating plate 301. The inner wall of the sealing sleeve 307 is in contact with the inner wall of the casting cavity 2. The sealing sleeve 307 facilitates full contact between the side wall of the sealing sleeve 307 and the casting cavity 2, thereby improving the sealing performance between the floating plate 301 and the casting cavity 2.

[0023] Furthermore, the surface of the fixed column 304 is provided with multiple sliding grooves 308, and multiple sliding blocks 309 are fixedly connected to the inner wall of the sliding hole 303. The sliding blocks 309 are slidably connected to the inner wall of the sliding groove 308. The sliding grooves 308 and the sliding blocks 309 cooperate with each other to facilitate the limiting of the connecting frame 302, thereby facilitating the linear up and down movement of the floating plate 301.

[0024] Furthermore, a positioning frame 310 is rotatably connected to the surface of the fixed column 304. The positioning frame 310 is fixedly connected to the inner wall of the main body mold 1. The positioning frame 310 facilitates the positioning of the fixed column 304.

[0025] Furthermore, the main body mold 1 is composed of an upper mold and a lower mold. The bottom surface of the upper mold is provided with an embedding groove 311, and the lower mold abuts against the inner wall of the embedding groove 311. By abutting against the inner wall of the embedding groove 311, the tightness of the connection between the upper mold and the lower mold is improved.

[0026] Working principle: Through the floating component 3, the floating plate 301 remains on the bottom surface of the inside of the casting cavity 2 when not being injected. Multiple injection delivery pipes are fixedly connected to the inner walls of multiple connectors 306. When the injection delivery pipes start to deliver material, the injection material is directly conveyed to the bottom surface of the floating plate 301 through the connectors 306. As the material on the bottom surface of the floating plate 301 increases and is continuously conveyed, the material is squeezed against each other, thus pushing the floating plate 301 to float upward first, and then continuing to convey material until the floating plate 301 is pushed to the top surface of the inside of the casting cavity 2. When the material on the bottom surface of the floating plate 301 is squeezed against each other, the material is in full contact with the material, thereby reducing the probability of air bubbles appearing after uneven material filling during deep cavity injection.
