Description

Technical Field

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

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] After the product is removed from the injection molding process, the surface temperature of the product is relatively high, around 75°C. If the product is placed directly on the production line at this temperature, it will still be in the process of shrinking and is prone to local deformation, which will lead to product defects. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a rapid cooling and shaping device for plastic products, which has a simple structure and layout, enabling the product to achieve a rapid cooling effect within a certain period of time.

[0005] To achieve the above objectives, the present invention employs the following:

[0006] This utility model provides a rapid cooling and shaping device for plastic products, which includes a base. A straightening fixture is arranged in the middle of the upper surface of the base. The upper surface of the base is also provided with three sets of fan fixing frames respectively arranged in front of, to the left of and to the right of the straightening fixture. There is a gap between the three sets of fan fixing frames and the straightening fixture. Each fan fixing frame is provided with a fan module whose air outlet can be perpendicular to the straightening fixture. The height of the fan module is not higher than the height of the straightening fixture.

[0007] According to the present invention, a rapid cooling and shaping device for plastic products is provided. The straightening fixture includes a base and two side profile plates vertically disposed on the upper surface of the base. The two side profile plates are at the same height and parallel to each other, and there is a gap between the two side profile plates. In this way, the two side profile plates are used to spread and hold the two sides of the U-shaped plastic product open and abut against it, so that its shape can be maintained without deformation during the cooling process. Thus, the plastic product will not shrink and deform due to local cooling during the cooling process.

[0008] Furthermore, the outer wall of the side profile plate has a profiled portion for conforming to the inner wall of the plastic product. This ensures that the plastic product can be placed very snugly on the two side profile plates, guaranteeing that the plastic product can maintain a stationary posture during the cooling process.

[0009] According to the present invention, a rapid cooling and shaping device for plastic products is provided, wherein a filter plate is installed at the air outlet of the fan module. This filter plate can filter dust and other contaminants carried from the air outlet of the fan module, ensuring the cleanliness of the plastic product's surface.

[0010] Furthermore, it also includes a lifting frame, which is a cuboid frame structure, with the base horizontally positioned on top of the lifting frame. The lifting frame allows the rapid cooling and shaping device to adapt to the height of the robotic arm of the automatic take-off machine on the production line, and also meets the needs of organizing the line control box and moving the rapid cooling and shaping device.

[0011] Furthermore, the top of the lifting frame is also equipped with a cover plate to surround the rapid cooling and shaping device. The cover plate is hollow inside, with one side open, and an opening in the middle of the top surface for placing plastic products downwards. The cover plate protects the straightening fixtures, fan modules, and plastic products placed on the base during operation, and its installation does not affect the placement or removal of plastic products.

[0012] Furthermore, several ventilation slots are arranged in a row on the other three sides of the baffle body. These ventilation slots allow airflow to escape from the lower part of the baffle body, preventing heat from accumulating between the base and the baffle body.

[0013] Furthermore, the lifting frame has a horizontal reserved placement shelf in the middle. This shelf is used to place the wiring control box, facilitating wiring organization.

[0014] Furthermore, each of the four corners of the bottom of the lifting frame is equipped with a set of omnidirectional wheels. These wheels facilitate the movement of this rapid cooling and shaping device, making it convenient and practical, and meeting the transportation needs of different scenarios.

[0015] Compared with the prior art, the present invention has the following technical effects: the present invention has a simple structure and reasonable design; the straightening fixture ensures that the plastic product will not shrink or deform during the rapid cooling process; the fan module arranged on three sides achieves rapid air cooling of the plastic product placed on the straightening fixture, which has fast cooling efficiency and low cost.

[0021] To more clearly illustrate this utility model, the following description, in conjunction with preferred embodiments, further clarifies the invention. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Example 1:

[0024] Please see Figure 1 As shown in the figure. This utility model embodiment proposes a rapid cooling and shaping device for plastic products, including a horizontal base 2, a straightening fixture 3 arranged in the middle of the upper surface of the base 2, and three sets of fan fixing frames 4 respectively arranged in front, to the left and to the right of the straightening fixture 3 on the upper surface of the base 2. There is a gap between the three sets of fan fixing frames 4 and the straightening fixture 3. Each fan fixing frame 4 is provided with two fan modules 5 whose air outlets are perpendicular to the straightening fixture. The height of the fan modules 5 is not higher than the height of the straightening fixture 3.

[0025] The plastic product 1 to be cooled in this embodiment has a U-shaped structure. The wings on both sides of the product have a certain height and there is no supporting reinforcement design on the sides. The product will shrink and deform during the cooling process, resulting in unstable quality and NG.

[0026] Based on the plastic product 1, the corrective fixture designed in this embodiment can support its two wings. The corrective fixture 3 includes a base 31 and two side profile plates 32 vertically disposed on the upper surface of the base 31. The two side profile plates 32 are at the same height and parallel to each other, and there is a gap between the two side profile plates 32. In this way, the two side profile plates are used to spread and hold the two sides of the U-shaped plastic product open to maintain its shape and prevent deformation during the cooling process. Thus, the plastic product will not shrink and deform due to local cooling during the cooling process.

[0027] The outer wall of the side profile plate 32 has a profiled part for fitting against the inner wall of the plastic product 1. This ensures that the two wings of the plastic product can be placed very close to the outer walls of the two side profile plates, ensuring that the plastic product can maintain a stationary posture during the cooling process. The distance between the two side profile plates is adjusted according to different models of plastic products.

[0028] In this embodiment, a filter plate is installed at the air outlet of each fan module 5 (the specific structure of the filter plate is not shown in the figure; the filter plate is a standard part and can be used directly). This filter plate can filter dust and other contaminants carried out from the air outlet of the fan module, ensuring the cleanliness of the plastic product's surface.

[0029] Example 2:

[0030] like Figure 2 and Figure 3 As shown, this embodiment proposes an auxiliary cooling device, including the rapid cooling and shaping device of Embodiment 1, and also includes a lifting frame 6. The lifting frame 6 is a vertically oriented cuboid frame structure, and the base 2 of the rapid cooling and shaping device is horizontally disposed on the top of the lifting frame 6. The lifting frame enables the rapid cooling and shaping device to adapt to the height of the robotic arm of the automatic take-off machine on the production line, and to meet the needs of organizing the line control box and moving the rapid cooling and shaping device.

[0031] The lifting frame 6 is equipped with a cover plate 7 on its top to enclose the rapid cooling and shaping device. The cover plate 7 is hollow inside, with an open side, and an opening 71 in the middle of its top surface for placing the plastic product 1 downwards. The cover plate protects the straightening fixture, fan module, and plastic products placed on the base during operation, and its installation does not affect the placement or removal of the plastic products.

[0032] It is worth noting that several ventilation slots 72 are arranged in a row on the other three sides of the baffle body 7. The ventilation slots allow airflow to escape from the lower part of the baffle body, preventing heat from accumulating between the base and the baffle body.

[0033] In addition, a horizontal reserved placement shelf 61 is provided in the middle of the lifting frame 6. This shelf is used to place the wiring control box for easy wiring organization.

[0034] In addition, each of the four corners of the bottom of the lifting frame 6 is equipped with a set of omnidirectional wheels 62. The omnidirectional wheels facilitate the movement of this rapid cooling and shaping device, making it convenient and practical, and meeting the needs of movement in different scenarios.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
