[0001] This utility model belongs to the field of injection mold technology, specifically relating to an injection molding mold with good cooling effect. Background Technology

[0002] A wheel hubcap (commonly referred to as a hubcap) is a protective and decorative component installed in the center of a car wheel hub. Wheel hubcaps are manufactured using injection molding, where plastic material is injected into a mold and, after cooling and solidification, forms the desired wheel hubcap part.

[0003] Patent CN220429179U discloses "an injection molding mold with good cooling effect, including a base, a lower mold base is provided on the upper part of the base, a cooling cavity is opened in the inner wall of the lower mold base, and an upper mold base is provided above the lower mold base. This utility model is provided with a lower mold base, an upper mold base, a telescopic component one, a horizontal plate, a water storage base, a water injection pipe one, a sealing mechanism, an L-shaped rod, a telescopic component two, a sealing plug two, and a water injection pipe, which can automatically inject water to cool the inside of the mold after injection molding, and has the advantages of high automation, good cooling effect and high injection efficiency."

[0004] Although the existing technology can cool the mold by injecting water after injection molding, the fact that water cooling can only be performed after injection molding will prolong the cooling and molding time of the product inside the mold and reduce production efficiency, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide an injection molding mold with good cooling effect in order to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] An injection molding mold with good cooling effect includes a base plate, a lower mold base fixedly disposed on the top of the base plate, an upper mold base mating and abutting against the top of the lower mold base, and a cooling mechanism disposed between the lower mold base and the upper mold base. The cooling mechanism includes a spiral cooling channel opened in the lower mold base and the upper mold base, and a fan mechanism disposed on the outside of the lower mold base. The fan mechanism includes two sets of rotating plates rotatably disposed on both sides of the lower mold base, two connecting rods respectively rotatably disposed between the two sets of rotating plates, a horizontal plate rotatably disposed between the bottom ends of the two connecting rods, and an electric push rod fixedly disposed between the top of the horizontal plate and the bottom of the base plate.

[0008] As a further optimization of this utility model, a number of positioning holes are provided at the top edge of the lower mold base, and a number of positioning rods that are fitted into the positioning holes are fixedly provided at the bottom of the upper mold base.

[0009] As a further optimization of this utility model, an injection hole is provided on the top of the upper mold base.

[0010] As a further optimization of this utility model, both the lower mold base and the upper mold base are fixedly provided with water inlet pipes for injecting coolant into the spiral cooling channel, and both the lower mold base and the upper mold base are fixedly provided with drain pipes for discharging coolant from the spiral cooling channel.

[0011] As a further optimization of this utility model, a limiting groove is provided on the bottom inner side of the lower mold base, and a matching pusher plate is movably provided on the top of the limiting groove of the lower mold base. A square rod is fixedly provided at the bottom end of the pusher plate, and the square rod is movably provided in the matching limiting groove.

[0012] As a further optimization of this utility model, a push rod is fixedly provided at the top of the horizontal plate for lifting the square rod upward when the electric push rod continues to shorten.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through structures such as spiral cooling channels, the mold can be cooled during the injection molding process, thereby reducing the cooling and molding time of the product inside the mold and improving production efficiency. When the electric push rod extends and retracts within a certain range, it will use the connecting rod to drive the two sets of rotating plates to rotate back and forth to fan the mold, accelerate the airflow around the mold for heat dissipation, and thus improve the cooling effect of the mold.

[0015] 2. By continuously shortening the electric push rod, the ejector rod can be continuously moved upward to lift the square rod. As the square rod moves upward, the ejector plate can push the product in the lower mold base upward to assist demolding. This makes it easy for workers to quickly remove the injection-molded product. The whole process only requires a single electric push rod to complete multiple processes such as fanning and assisting demolding, which is convenient and practical. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1-3 As shown, an injection mold with good cooling effect includes a base plate 1, a lower mold base 2, an upper mold base 3, and a cooling mechanism. The base plate 1 can be installed on injection molding equipment such as an injection molding machine. The lower mold base 2 is fixedly installed on the top of the base plate 1. The upper mold base 3 is fitted against the top of the lower mold base 2. The upper mold base 3 can be installed on the cylinder of an external injection molding equipment. The upper mold base 3 is moved up and down by the extension and retraction of the cylinder, thereby performing mold closing and mold separation.

[0023] like Figure 2-3 As shown, a number of positioning holes 21 are provided at the top edge of the lower mold base 2, and a number of positioning rods 32 are fixedly provided at the bottom of the upper mold base 3 and are inserted into the positioning holes 21. After the positioning rods 32 are inserted into the positioning holes 21, they can connect and position the lower mold base 2 and the upper mold base 3, so that the lower mold base 2 and the upper mold base 3 can be aligned and aligned with each other.

[0024] like Figure 2-3 As shown, the top of the upper mold base 3 is provided with an injection hole 31, through which external injection molding equipment can inject plastic raw materials into the mold to perform injection molding of products such as automobile wheel hub caps.

[0025] like Figure 2-3 As shown, the cooling mechanism is located between the lower mold base 2 and the upper mold base 3. The cooling mechanism includes a spiral cooling channel 4 opened in the lower mold base 2 and the upper mold base 3, and a fan mechanism located on the outside of the lower mold base 2. The spiral cooling channel 4 can increase the contact area between the internal coolant and components such as the lower mold base 2, thereby improving the cooling effect. The fan mechanism can fan the surrounding area of ​​the mold to assist in heat dissipation.

[0026] like Figure 1-2As shown, both the lower mold base 2 and the upper mold base 3 are fixedly equipped with inlet pipes 41 for injecting coolant into the spiral cooling channel 4, and both the lower mold base 2 and the upper mold base 3 are fixedly equipped with drain pipes 42 for draining coolant from the spiral cooling channel 4. Both inlet pipes 41 and drain pipes 42 are connected to an external coolant circulation cooling device. The external coolant circulation cooling device is a publicly available technology and will not be described in detail here. During the injection molding process, the inlet pipe 41 continuously injects coolant into the spiral cooling channel 4, while the drain pipe 42 continuously drains coolant from the spiral cooling channel 4 to continuously cool the lower mold base 2 and the upper mold base 3, thereby reducing the cooling and molding time of the product in the mold and improving production efficiency.

[0027] like Figure 1-2 As shown, the fan mechanism includes two sets of rotating plates 5 rotatably disposed on both sides of the lower mold base 2, two connecting rods 51 rotatably disposed between the two sets of rotating plates 5, a horizontal plate 52 rotatably disposed between the bottom ends of the two connecting rods 51, and an electric push rod 53 fixedly disposed between the top of the horizontal plate 52 and the bottom of the base plate 1. The connecting rods 51 can connect the horizontal plate 52 and the rotating plates 5. The electric push rod 53 can be a Thomson 3SC series electric cylinder.

[0028] The operator can control the electric push rod 53 to reciprocate within a certain range, thereby using the connecting rod 51 to drive the two sets of rotating plates 5 to reciprocate and swing up and down. After reciprocating, the two sets of rotating plates 5 can fan the mold, accelerate the airflow around the mold to dissipate heat, and thus improve the cooling effect of the mold.

[0029] like Figure 2-3 As shown, a limiting groove 22 is provided on the bottom inner side of the lower mold base 2. A matching pusher plate 23 is movably provided on the top of the limiting groove 22 of the lower mold base 2. A square rod 24 is fixedly provided on the bottom end of the pusher plate 23. The square rod 24 is movably provided in the matching limiting groove 22. A push rod 54 is fixedly provided on the top of the horizontal plate 52 for pushing the square rod 24 upward when the electric push rod 53 continues to shorten. A through hole is provided in the bottom plate 1 for the push rod 54 and the connecting rod 51 to pass through. The lower mold base 2 can support and limit the pusher plate 23 and the square rod 24 through the limiting groove 22. The square rod 24 can limit the pusher plate 23, so that the pusher plate 23 can move up and down.

[0030] When the upper mold base 3 is removed after injection molding, the electric push rod 53 is continuously shortened by controlling it, which drives the ejector rod 54 to move upward and contact the square rod 24, thus lifting the square rod 24 upward. As the square rod 24 moves upward, the push plate 23 pushes the product in the lower mold base 2 upward to assist in demolding and facilitate the quick removal of the injection-molded product by the staff.

[0031] It should be noted that, in the use of this injection molding mold with good cooling effect, external injection molding equipment can inject molten plastic raw materials into the mold through the injection hole 31 to perform injection molding of products such as automobile wheel hub caps.

[0032] Meanwhile, during the injection molding process, the water inlet pipe 41 continuously injects coolant into the spiral cooling channel 4, while the drain pipe 42 continuously discharges the coolant from the spiral cooling channel 4. By utilizing the spiral cooling channel 4 and other structures, the lower mold base 2 and the upper mold base 3 are continuously cooled, thereby reducing the cooling and molding time of the product in the mold and improving production efficiency.

[0033] It can control the electric push rod 53 to reciprocate within a certain range, thereby using the connecting rod 51 to drive the two sets of rotating plates 5 to reciprocate and swing up and down. After reciprocating, the two sets of rotating plates 5 can fan the mold, accelerate the air flow around the mold to dissipate heat, thereby improving the cooling effect of the mold.

[0034] When the upper mold base 3 is removed after injection molding, the electric push rod 53 is continuously shortened by controlling it, which drives the ejector rod 54 to move upward and contact the square rod 24, thus lifting the square rod 24 upward. As the square rod 24 moves upward, the push plate 23 pushes the product in the lower mold base 2 upward to assist in demolding and facilitate the quick removal of the injection-molded product by the staff.

[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
