Description

Technical Field

[0001] This utility model relates to the field of injection molded part cooling technology, specifically to a cooling device for injection molded parts after injection molding. Background Technology

[0002] Injection molded parts are plastic components formed by heat treatment and injection molding of plastic granules such as polyurethane granules and polytetrafluoroethylene granules. Because they are made of plastic, injection molded parts have low production costs and a simple manufacturing process. Various shapes and sizes of parts can be produced through injection molding. For example, the housing of the shock absorber air bag used in automobiles is produced by injection molding. During the production of injection molded parts, although the product is cooled during the injection molding process, a certain temperature remains on the surface of the part after unloading. The plastic material of injection molded parts makes them susceptible to high temperatures and pressure, especially under pressure. If the surface of the part is not sufficiently cooled during injection molding, it is very easy to deform under pressure during stacking.

[0003] A search revealed that patent application number 202421285484.4 discloses a post-injection cooling device for injection molded parts. The device includes a vertically arranged cooling cylinder with several air-blowing cooling mechanisms for cooling the injection molded parts mounted on it. The device also includes several slow-fall mechanisms installed within the cooling cylinder, arranged in upper and lower layers. Each slow-fall mechanism comprises several annularly distributed slow-fall plates, each hinged to a hinge seat fixedly connected to the inner wall of the cooling cylinder. Inclined tension springs are fixedly connected to the slow-fall plates and to the inner wall of the cooling cylinder. During the injection molding process, the elastically pulled slow-fall plates flip, releasing the injection molded parts and delaying their descent. This device achieves both ensuring the injection molded parts can pass through and extending their passage time, thus increasing their time through the cooling cylinder while maintaining a high throughput, meeting the requirements for batch cooling efficiency.

[0004] The aforementioned application documents describe how air cooling is used to cool the drop-type plastic parts through various components. However, the cooling effect of air cooling alone is limited and it is difficult to efficiently cool the plastic parts according to the needs. Furthermore, the application documents do not disclose how to efficiently treat the water droplets left on the outer wall of the plastic parts after water cooling.

[0005] Therefore, we propose a cooling device for injection molded parts after injection molding. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a post-injection cooling device for injection molded parts, which solves the problem that existing devices are unable to efficiently water-cool plastic parts and subsequently air-cool them to remove adhering water droplets.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a cooling device for injection molded parts after injection molding, comprising a base and an arc seat fixedly installed on it, wherein an arc track is fixedly connected to the edge of the arc seat;

[0008] A drive motor is fixedly installed at the bottom of the arc seat, and a liquid-spinning mechanism for placing water-cooled demolded plastic parts is fixedly connected to the top of the output shaft of the drive motor. A liquid pump is fixedly installed at the bottom of the arc seat, and a liquid frame mounted on the liquid pump is provided at the top of the arc channel.

[0009] As a preferred embodiment of the present invention, a liquid cavity is provided on the inner side of the liquid frame, a liquid hole for discharging liquid outward is opened on the front side of the liquid frame, and the output end of the liquid pump is connected to the liquid frame through a liquid pipe.

[0010] The liquid frame and its front liquid hole facilitate the discharge of liquid from the liquid pump through the liquid pipe, thereby water cooling the plastic parts rolling on the arc track and ensuring efficient cooling of the plastic parts.

[0011] As a preferred embodiment of this utility model, a blower pump is fixedly installed at the bottom of the arc seat, which is opposite to the position of the liquid pump. The output end of the blower pump is fixedly connected to a duct, and the outer end of the duct is fixedly connected to a liquid-throwing mechanism, and a corresponding cold airflow is transmitted in the liquid-throwing mechanism.

[0012] The fan pump is designed to discharge air-cooled air through the air duct and then discharge the air-cooled air downwards from the top side, thereby performing efficient air-cooling processing on the water-cooled plastic parts placed on the liquid-spraying mechanism.

[0013] As a preferred embodiment of the present invention, the liquid-throwing mechanism includes a sieve bucket and an arc ring on its top side. The sieve bucket and the arc ring are assembled together by a bearing ring. The sieve bucket has a sieve hole in the shape of a filling hole, and the bottom of the sieve bucket is fixedly connected to the top of the output shaft of the drive motor.

[0014] The sieve bucket and its sieve holes are designed to eject water droplets left on the outer wall of the plastic parts when driven by the motor to rotate, while the bearing ring ensures that the sieve bucket rotates stably under the drive.

[0015] As a preferred embodiment of this utility model, five sets of slides are fixedly connected to the top of the arc ring, and the five sets of slides are fixedly connected to the bottom of the arc track. An arc-shaped diversion pipe is fixedly connected to the top of the arc ring, and the diversion pipe is fixedly connected to the output end of the diversion plate. The bottom of the diversion pipe is provided with air holes for air cooling of the plastic parts placed on the top side of the sieve bucket.

[0016] The five sets of slides facilitate the fixed installation of the liquid-spraying mechanism on the arc track, and the plastic parts can slide from the arc track to the liquid-spraying mechanism by sliding on the slides, thus achieving the air-cooling effect after water cooling.

[0017] As a preferred embodiment of this utility model, the top surface of the arc track is a smooth surface, baffles are provided on both sides of the arc track to block their inner sides, and a demolded plastic part that slides downward is placed on the arc track.

[0018] The baffle is designed to prevent liquid from leaking out of the arc.

[0019] This utility model provides a cooling device for injection molded parts after injection molding. It has the following beneficial effects:

[0020] This injection molding post-injection cooling device, through the arrangement of various components on the base, utilizes the components on the liquid pump to perform liquid cooling on the rolling plastic parts. The liquid-spinning mechanism and the components on the fan pump can spin-dry the sliding and water-cooled plastic parts and then blow-dry them with air, ensuring efficient cooling of the plastic parts. This solves the problem that existing devices are unable to perform efficient water cooling and subsequent air cooling of adhering water droplets on plastic parts according to requirements.

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a cooling device for injection molded parts after injection molding, including a base 1 and an arc seat 2 fixedly installed on it, an arc track 9 fixedly connected to the edge of the arc seat 2; a drive motor 3 fixedly installed at the bottom of the arc seat 2, a liquid ejection mechanism 8 for placing water-cooled demolded plastic parts fixedly connected to the top of the output shaft of the drive motor 3, a liquid pump 4 fixedly installed at the bottom of the arc seat 2, and a liquid frame 11 assembled on the liquid pump 4 at the top of the arc track 9;

[0028] The injection molding cooling device utilizes the components on the base 1 and the components on the liquid pump 4 to perform liquid cooling on the rolling plastic part. The components on the liquid-spinning mechanism 8 and the fan pump 5 can spin-dry the slid-down and water-cooled plastic part and then air-dry it, ensuring efficient cooling of the plastic part. This solves the problem that existing devices cannot efficiently water-cool the plastic part and air-cool it to remove water droplets as needed.

[0029] Example 2:

[0030] The inner side of the liquid frame 11 is provided with a liquid cavity, and the front side of the liquid frame 11 is provided with a liquid hole 12 for discharging liquid outward. The output end of the liquid pump 4 is connected to the liquid frame 11 through the liquid pipe 6. The liquid frame 11 and the liquid hole 12 on its front side are provided to facilitate the liquid pump 4 to discharge liquid outward through the liquid pipe 6, thereby water cooling the plastic parts rolling on the arc track 9 and ensuring a high-efficiency cooling effect for the plastic parts.

[0031] A fan pump 5 is fixedly installed at the bottom of the arc seat 2, opposite to the position of the liquid pump 4. The output end of the fan pump 5 is fixedly connected to the air duct 7, and the outer end of the air duct 7 is fixedly connected to the liquid-throwing mechanism 8, and the liquid-throwing mechanism 8 transmits a corresponding cold air flow. The fan pump 5 is configured to discharge the cold air flow through the air duct 7, and then discharge the cold air flow from the top side downward, thereby performing efficient air-cooling processing on the water-cooled plastic parts placed on the liquid-throwing mechanism 8.

[0032] The liquid-throwing mechanism 8 includes a sieve bucket 81 and an arc ring 82 on its top side. The sieve bucket 81 and the arc ring 82 are assembled together by a bearing ring. The sieve bucket 81 has a sieve hole in the shape of a filling hole, and the bottom of the sieve bucket 81 is fixedly connected to the top of the output shaft of the drive motor 3. The sieve bucket 81 and the sieve hole are designed to throw out water droplets left on the outer wall of the plastic part when it is driven to rotate by the drive motor 3. The bearing ring ensures that the sieve bucket 81 rotates stably under the drive.

[0033] Five sets of slides 13 are fixedly connected to the top of the arc ring 82. The five sets of slides 13 are fixedly connected to the bottom of the arc track 9. An arc-shaped diversion pipe 84 is fixedly connected to the top of the arc ring 82. The diversion pipe 84 is fixedly connected to the output end of the diversion plate 83. The bottom of the diversion pipe 84 is provided with air holes for air cooling of the plastic parts placed on the top side of the sieve hopper 81. The arrangement of the five sets of slides 13 facilitates the fixed installation of the liquid-throwing mechanism 8 on the arc track 9. The plastic parts can slide from the arc track 9 to the liquid-throwing mechanism 8 by sliding on the slides 13, thus achieving the effect of air cooling after water cooling.

[0034] The top surface of the arc track 9 is a smooth surface. Baffles 10 are provided on both sides of the arc track 9 to block its inner side, and a demolded plastic part that slides downward is placed on the arc track 9. The baffles 10 can prevent liquid from leaking out of the arc track 9.

[0035] The working principle and usage process of this utility model are as follows: When the device is required to work, the demolded plastic part falls on the arc track 9 and rolls down along it, passing through the top side of the slide 13 and rolling to the inner side of the liquid-throwing mechanism 8. At the same time, the liquid pump 4 can transport the liquid flow inside the arc seat 2 to the liquid frame 11 and spray the liquid flow outward from the liquid hole 12 to perform water cooling processing on the plastic part rolling on the arc track 9. Then, the drive motor 3 is turned on to drive the screen bucket 81 in the liquid-throwing mechanism 8 to rotate, and drive the plastic part on its top side to rotate and throw off the residual liquid droplets on the plastic part. At the same time, the blower pump 5 discharges the air-cooled airflow downward through the diversion pipe 84 to perform air-cooled drying processing on the plastic part on the screen bucket 81. This solves the problem that the existing device is difficult to perform efficient water cooling and subsequent air-cooling processing of the plastic part and the water droplets that adhere to it according to the requirements.
