Description

Technical Field

[0001] This utility model relates to the field of bobbin production technology, and more specifically, to a temperature control device for injection molded bobbins. Background Technology

[0002] A spool is a product used to wind yarn. Spools are widely used in the textile industry, and most are currently made of plastic, although some are made of paper pulp.

[0003] During the cooling stage of injection molding, the spool mainly cools within the mold using circulating water or other cooling media. However, due to production efficiency limitations, the mold cooling time is usually short, making it impossible to completely cool the plastic part to room temperature. When demolding, residual heat may still remain inside the spool, especially in areas with thicker walls. If heat dissipation is not continued, it may lead to subsequent deformation or dimensional instability. Current methods mostly involve placing the spool directly to allow it to cool naturally to room temperature, but this results in a longer cooling time, which is not conducive to rapid production and use. Furthermore, dust tends to accumulate during heat dissipation, affecting product quality and hindering subsequent use.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] (II) Technical Solution

[0009] A temperature control device for injection molding spools includes a cooling box and support legs. A bearing plate is fixedly installed in the middle of the interior of the cooling box. Several sets of cooling plates are evenly installed on the surface of the bearing plate. Several sets of second air vents are evenly arranged around the surface of the cooling plates. A limit tube is slidably connected in the middle of the cooling plates and passes through the bearing plate. Several sets of first air vents are evenly arranged around the top of the surface of the limit tube.

[0010] Furthermore, slide rods are symmetrically installed on both sides of the bottom of the support plate, and a movable plate is slidably connected to the outer periphery of the slide rods. The top of the movable plate is connected to the limiting tube.

[0011] Furthermore, an exhaust plate is installed at the top of the cooling box, and several sets of exhaust hoods are evenly installed at the bottom of the exhaust plate. The exhaust plate is connected to an exhaust fan through a pipe.

[0012] Furthermore, a blower is installed at the bottom center of the cooling box, and the blower is connected to the moving plate through an air supply pipe.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a temperature control device for injection molding spools, which has the following advantages:

[0019] (1) This utility model adopts a limiting tube and a cooling plate. Personnel can place the injection molding spool that needs to be cooled on the cooling plate on the support plate and make it wrap around the outer periphery of the limiting tube. Then, the external cooling air can be continuously introduced by the blower. At this time, the air can enter the limiting tube and the cooling plate through multiple sets of air supply pipes respectively. The air entering the limiting tube can be sprayed out from multiple sets of first air outlets on its surface and then act on the inner surface of the spool. The air in the cooling plate can be sprayed out through the second air outlet and then act on the outer surface of the spool. The device can improve the overall cooling efficiency and cooling uniformity through the double air cooling operation inside and outside, avoid uneven cooling inside and outside that causes deformation of the spool, ensure product quality, and has the advantages of good heat dissipation effect and high heat dissipation efficiency.

[0020] (2) By using a dustproof net, the spools that need to be cooled can be placed in the cooling box during operation to avoid contact with external impurities and reduce the probability of contamination. At the same time, the operation of the blower blowing air from bottom to top and the exhaust fan blowing air from bottom to top inside the box can extract the internal hot air in time, avoid heat accumulation, and improve the cooling effect. Moreover, dustproof nets are installed at the fan positions to effectively prevent dust from entering and thus prevent contamination of the spools, ensuring the quality of the spools in subsequent use. It has the advantages of low heat dissipation and pollution. Attached Figure Description

[0029] According to an embodiment of the present invention, a temperature control device for injection molding spools is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a temperature control device for injection molding spools according to an embodiment of the present invention includes a cooling box 1 and a support leg 13. A bearing plate 4 is fixedly installed in the middle of the interior of the cooling box 1. Several sets of cooling discs 11 are evenly installed on the surface of the bearing plate 4. Several sets of second air outlets 10 are evenly arranged around the surface of the cooling discs 11. A limiting tube 8 is slidably connected in the middle of the cooling discs 11 and passes through the bearing plate 4. Several sets of first air outlets 9 are evenly arranged around the top of the surface of the limiting tube 8. The first air outlets 9 and the second air outlets 10 are designed to spray out cold air, thereby realizing synchronous air cooling operation on the inside and outside of the spool, improving cooling uniformity, and facilitating better cooling.

[0031] In one embodiment, slide rods 2 are symmetrically installed on both sides of the bottom of the support plate 4. A movable plate 3 is slidably connected to the outer periphery of the slide rods 2. The top of the movable plate 3 is connected to the limiting tube 8. The slide rods 2 are set to limit the movement of the movable plate 3 and ensure its movement stability.

[0032] In one embodiment, an exhaust plate 5 is installed at the top of the cooling box 1, and several sets of exhaust hoods 6 are evenly installed at the bottom of the exhaust plate 5. The exhaust plate 5 is connected to an exhaust fan 7 through a pipe. The exhaust fan 7 is set up to extract the hot air inside the cooling box 1 to prevent heat accumulation.

[0033] In one embodiment, a blower 14 is installed at the bottom center of the cooling box 1. The blower 14 is connected to the movable plate 3 through an air supply pipe 16. The blower 14 is set up to introduce external cold air, thereby realizing the cooling operation of the spool.

[0034] In one embodiment, cavities for gas flow are provided inside the moving plate 3, the limiting tube 8, and the exhaust plate 5. The cavities are designed to facilitate gas flow, thereby enabling the introduction and ejection of cold air and the extraction and release of hot air, thus facilitating the cooling operation of the spool.

[0035] In one embodiment, support legs 13 are symmetrically installed on both sides of the bottom of the cooling box 1. The support legs 13 can fix the entire device, thereby enhancing the overall stability of the device.

[0036] In one embodiment, cylinders 12 are symmetrically installed on both sides of the bottom of the movable plate 3. The cylinders 12 are used to raise and lower the movable plate 3, thereby adjusting the height of the limit tube 8.

[0037] In one embodiment, dustproof nets 15 are provided on the surfaces of both the blower 14 and the exhaust fan 7. The purpose of the dustproof nets 15 is to block dust and prevent it from entering the cooling box 1 and contaminating the spool, thus ensuring the product quality of the spool and preventing subsequent contamination of the yarn.

[0038] Working Principle: In actual use, personnel can place the injection-molded spool requiring cooling onto the cooling plate 11 on the support plate 4, ensuring it wraps around the periphery of the limiting tube 8. Then, a blower 14 continuously introduces external cooling air. This air enters the limiting tube 8 and the cooling plate 11 through multiple air supply pipes 16. Air entering the limiting tube 8 is ejected from multiple first air outlets 9 on its surface, acting on the inner surface of the spool. Air from the cooling plate 11 is ejected through second air outlets 10, acting on the outer surface of the spool. This dual internal and external air cooling operation not only improves overall cooling efficiency but also enhances cooling uniformity, preventing uneven internal and external cooling. This process prevents the spool from deforming, ensuring product quality. The system employs a blower 14 that blows air upwards and an exhaust fan 7 that exhausts air upwards, effectively removing internal heat and preventing heat buildup, thus improving cooling efficiency. Dust screens 15 are installed at each fan location to effectively prevent dust intrusion and contamination of the spool, ensuring its continued quality. After the spool has cooled, the cylinder 12 retracts, causing the moving plate 3 to move downwards, which in turn moves the limiting tube 8 on its surface. This allows the outer spools to be quickly removed without individual pulling, improving work efficiency and facilitating better use. The device as a whole has the advantages of good heat dissipation, high heat dissipation efficiency, and low heat pollution.
