Description

Technical Field

[0001] This utility model relates to the field of injection molding product processing, and in particular to a cooling and shaping device for injection molded products. Background Technology

[0002] When injection molded products are first ejected from the mold, they retain residual heat. Natural cooling is generally used to cool the injection molded products. However, natural cooling can easily cause product deformation and shrinkage, which directly affects the product yield.

[0003] To address the potential deformation issues that may occur during the cooling process of injection molded products, existing technologies typically employ shaping fixtures to reshape the products. However, these fixtures can only be removed after the injection molded products have completely cooled before the next batch of products can be loaded, shaped, and cooled. This waiting period is time-consuming and prevents continuous loading and unloading of injection molded products during the cooling and shaping process, resulting in reduced shaping efficiency and failing to meet application requirements. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cooling and shaping device for injection molded products.

[0005] The technical solution of this utility model is as follows: it includes a frame, an electrical control box on the lower layer of the frame, and a cooling and shaping chamber on the upper layer. Several bearing plates are arranged and stacked in the cooling and shaping chamber at intervals along the vertical direction. The bearing plates can slide along the feeding direction of the injection molded product. Multiple shaping blocks that match the bottom surface of the injection molded product are distributed at intervals on the upper surface of each bearing plate. The injection molded product is pressed onto the shaping blocks and cooled by a cooling component.

[0008] Preferably, the support plate at the bottom of the cooling and shaping chamber is fixedly installed.

[0009] Preferably, the cooling assembly includes a cooling fan, which is mounted on a support plate and moves synchronously with the support plate.

[0010] Preferably, the cooling fan is a mirror-shaped cooling fan, which includes two sets of fans rotating in opposite directions.

[0011] Preferably, a pressing mechanism is provided on the support plate at a position corresponding to the shaping block.

[0021] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a cooling and shaping equipment for injection molded products, including a frame 1, an electrical control box 2 on the lower layer of the frame 1, and a cooling and shaping chamber on the upper layer of the frame 1, providing space for cooling and shaping of injection molded products.

[0023] The cooling and shaping chamber contains several support plates 3 arranged vertically at intervals and stacked. Injection-molded products on each support plate 3 are cooled by a cooling assembly 4. The cooling and shaping chamber has a loading port, and several slide rails on opposite sides allow the support plates 3 to slide. A linear slide rail 5 extending along the loading direction of the injection-molded products is mounted on the upper surface of each slide rail. The support plates 3 slide along the linear slide rail 5 under the drive of a loading motor 6. This sliding design of the support plates allows for continuous loading and unloading of the injection-molded products during the cooling and shaping process, resulting in a compact cycle and significantly improved production efficiency.

[0024] In this embodiment, the feeding motor 6 is a translation cylinder, which is fixed on the inner wall of the cooling and shaping chamber, and its output end is connected to the lower end face of the corresponding bearing plate 3.

[0025] To optimize the design and reduce costs, the bottom support plate 3 in the cooling and shaping chamber is fixedly installed without affecting the loading and unloading of injection molded products.

[0026] The cooling assembly 4 includes cooling fans, with multiple sets of cooling fans corresponding to several support plates 3. To further improve the heat dissipation efficiency of the injection molded product, mirrored cooling fans are used, each consisting of two sets of fans rotating in opposite directions. This design allows the airflow to form a more efficient convection path within the cooling and shaping chamber, thereby accelerating the exhaust of hot air and significantly improving heat dissipation efficiency. The cooling fans are installed at both ends of the support plates 3 perpendicular to the feeding direction and move synchronously with the support plates 3.

[0027] The upper surface of the support plate 3 is provided with a plurality of shaping blocks 31 that match the bottom surface of the injection molded product. The injection molded product that has just exited the mold is shaped and cooled by the shaping blocks 31 and the cooling component 4. A pressing mechanism 7 is provided on the support plate 3 at a position corresponding to the shaping blocks 31. When the injection molded product to be shaped is placed on the shaping block 31, the pressing mechanism 7 drives the injection molded product to move relative to the shaping block 31 and presses the injection molded product onto the shaping block 31.

[0028] like Figure 4 As shown, the pressing mechanism 7 includes a shaping plate 71 that is pressed and connected to the injection molded product, and a shaping cylinder 72 that drives the shaping plate 71 to move up and down relative to the shaping block 31.

[0029] In this embodiment, the shaping cylinder 72 is a rotary cylinder. When the shaping and cooling process begins, the rotary cylinder drives the shaping plate 71 to rotate and presses the injection molded product onto the shaping block 31 until the shaping and cooling process is completed. The shaping plate 71 is driven by the rotary cylinder to lift and rotate, thereby providing effective clearance space for the loading and unloading process of the injection molded product.

[0030] In order to improve the working efficiency of the rotary cylinder, the piston rod end of the rotary cylinder is provided with two sets of shaping pressure plates 71, which correspond one-to-one with the two sets of shaping blocks 31. The two sets of shaping pressure plates 71 are connected by a connecting rod.

[0031] To facilitate the unloading of injection molded products, a lifting mechanism 8 is provided below the forming block 31. The lifting mechanism 8 includes a lifting cylinder 81 fixed on the support plate 3 and a lifting block 82 that moves up and down under the drive of the lifting cylinder 81. A through hole is provided on the forming block 31 opposite to the lifting block 82 so that the lifting block 82 can pass through and complete the lifting and unloading of the injection molded product, preventing the injection molded product from being pressed tightly onto the forming block 31 after forming and cooling. The lifting mechanism 8 improves the efficiency of unloading injection molded products.

[0032] During operation, injection molded products are first fed onto the bottom support plate 3. Driven by the forming cylinder 72, the forming plate 71 presses the injection molded products onto the forming blocks 31. After the bottom support plate 3 is fed, the next support plate 3 is pushed out sequentially from bottom to top by the translation cylinder. When the last support plate 3 is fed, the injection molded products on the bottom support plate 3 have already cooled and shaped. Then, the injection molded products are fed out sequentially according to the order of their initial feeding. This cycle ensures a high product qualification rate while avoiding cooling time. The entire process is compact and highly efficient.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
