Description

Technical Field

[0001] This utility model relates to the field of vanadium battery technology, specifically to an injection molding device for vanadium battery flow channel plates. Background Technology

[0002] In the field of vanadium battery flow channel plate manufacturing, injection molding is a commonly used process. Injection molding can efficiently produce flow channel plates with certain shape and dimensional accuracy to meet the needs of vanadium batteries.

[0003] In the small-batch production or trial production stage of runner plates, due to the small production quantity and the possibility of product structure modifications, the cost of using automated equipment for injection molding is high. Therefore, non-automated traditional injection molding equipment is often used. Traditional equipment lacks an effective automatic demolding mechanism, which leads to extensive manual operation during the demolding process to remove the molded workpiece. Manual demolding is not only inefficient, increasing production cycle and labor costs, but also prone to damaging the workpiece, affecting product quality. Furthermore, manual demolding poses certain safety hazards, as operators may be injured due to misoperation. Therefore, we propose an injection molding device for vanadium battery runner plates. Utility Model Content

[0004] The purpose of this invention is to provide an injection molding device for vanadium battery flow channel plates to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection molding device for a vanadium battery flow channel plate, comprising a lower template and a lifting assembly. Multiple guide rods are mounted on the top surface of the lower template, and an upper mold is slidably mounted on the outer side of the multiple guide rods. A first elastic assembly connected to the upper mold is provided on the top surface of each guide rod. A guide post is mounted on the bottom surface of the lower template, and a lifting plate is slidably mounted on the outer side of the guide post. A top rod that slides through the bottom surface of the lower template is mounted on the top surface of the lifting plate, and a second elastic assembly connected to the lifting plate is mounted on the lower end of the guide post.

[0006] A first push plate is installed on one side of the upper mold, and a second push plate is installed on one side of the lifting plate. The lifting assembly is used to drive the first push plate and the second push plate to move vertically.

[0007] Preferably, the bottom surface of the lower template is equipped with support legs.

[0008] Preferably, the first elastic component includes a first baffle, which is mounted on one side of the guide rod. A first spring is mounted on one side of the first baffle, and the end of the first spring away from the first baffle is mounted on the top surface of the upper mold.

[0009] Preferably, the second elastic component includes a second baffle, which is installed at the lower end of the guide post, and a second spring is fixedly installed at the upper end of the second baffle. The end of the second spring away from the second baffle is installed on the bottom surface of the lifting plate.

[0010] Preferably, the second spring passes through the outside of the guide post.

[0011] Preferably, the lifting assembly includes an electro-hydraulic push rod, a connecting plate, and a limiting frame. The connecting plate is installed at the output end of the electro-hydraulic push rod, and the limiting frame is fixedly installed on one side of the connecting plate. The first push plate and the second push plate pass through the inner side of the limiting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The vanadium battery flow channel plate uses an injection molding device. After injection molding, the electric hydraulic push rod is extended, which drives the connecting plate and the limiting frame to move upward. The first baffle pulls the upper mold upward through the first spring to separate from the lower mold plate. As the limiting frame continues to move upward, the limiting frame pushes the second push plate upward. The second push plate drives the ejector rod upward through the lifting plate, so that the ejector rod pushes the finished product out of the lower mold cavity on the surface of the lower mold plate, thereby completing the automatic demolding work and eliminating the need for manual demolding.

[0014] 2. The vanadium battery flow channel plate uses an injection molding device. After the workpiece is removed, the electro-hydraulic push rod is controlled to retract, which drives the connecting plate and the limit frame to move downward. Under the action of the second spring, the lifting plate is pulled downward, so that the push rod moves downward and disengages from the lower mold cavity, allowing the lower mold cavity to be restored on the surface of the lower mold plate, which facilitates subsequent injection molding work.

[0019] 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.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides an injection molding device for vanadium battery flow channel plates, including a lower template 1 and a lifting assembly. Multiple guide rods 3 are installed on the top surface of the lower template 1, and an upper mold 4 is slidably installed on the outer side of the multiple guide rods 3. A first elastic assembly connected to the upper mold 4 is provided on the top surface of the guide rods 3. A guide post 7 is installed on the bottom surface of the lower template 1, and a lifting plate 8 is slidably installed on the outer side of the guide post 7. A top rod 9 that slides through the bottom surface of the lower template 1 is installed on the top surface of the lifting plate 8. A second elastic assembly connected to the lifting plate 8 is installed at the lower end of the guide post 7.

[0022] A first push plate 15 is installed on one side of the upper mold 4, and a second push plate 16 is installed on one side of the lifting plate 8. The lifting assembly is used to drive the first push plate 15 and the second push plate 16 to move vertically.

[0023] Specifically, the lifting assembly can drive the second push plate 16 to move upward, and after the workpiece is formed, the lifting plate 8 can drive the push rod 9 to push the workpiece out.

[0024] Among them: the bottom surface of the lower template 1 is equipped with a support leg 2. The support leg 2 is used to support the lower template 1.

[0025] Wherein: the first elastic component includes a first baffle 5, the first baffle 5 is installed on one side of the guide rod 3, a first spring 6 is installed on one side of the first baffle 5, and the end of the first spring 6 away from the first baffle 5 is installed on the top surface of the upper mold 4. When the first push plate 15 is not pressed by the limit frame 14, under the elastic force of the first spring 6, it can drive the upper mold 4 to move upward.

[0026] Wherein: the second elastic component includes a second baffle 10, which is installed at the lower end of the guide post 7. A second spring 11 is fixedly installed at the upper end of the second baffle 10. The end of the second spring 11 away from the second baffle 10 is installed on the bottom surface of the lifting plate 8. The second spring 11 passes through the outside of the guide post 7. After the lifting plate 8 enters the lower mold cavity of the lower mold plate 1, when the limiting frame 14 does not abut against the second push plate 16, the second spring 11 pulls the lifting plate 8 downward, so that the push rod 9 leaves the lower mold cavity of the lower mold plate 1.

[0027] The lifting assembly includes an electric hydraulic push rod 12, a connecting plate 13, and a limiting frame 14. The connecting plate 13 is installed at the output end of the electric hydraulic push rod 12, and the limiting frame 14 is fixedly installed on one side of the connecting plate 13. The first push plate 15 and the second push plate 16 pass through the inside of the limiting frame 14. When the switch of the electric hydraulic push rod 12 is turned on, the limiting frame 14 is lifted and lowered through the connecting plate 13, which in turn facilitates the movement of the first push plate 15 and the second push plate 16.

[0028] Working principle: This utility model is an injection molding device for vanadium battery flow channel plates. Before injection molding, the electric hydraulic push rod 12 is controlled to retract, which drives the connecting plate 13 and the limiting frame 14 to move downward. The limiting frame 14 pushes the first push plate 15 and the upper mold 4 downward, so that the upper mold 4 abuts against the top surface of the lower template 1, thus facilitating the injection molding process. After injection molding, the electric hydraulic push rod 12 is controlled to extend, which drives the connecting plate 13 and the limiting frame 14 to move upward. The first baffle 5 pulls the upper mold 4 upward through the first spring 6 to separate it from the lower template 1. As the limiting frame 14 continues to move upward, it pushes the second push plate 16 upward. The second push plate 16 drives the ejector rod 9 upward through the lifting plate 8, so that the ejector rod 9 pushes the finished product out of the lower mold cavity on the surface of the lower template 1, thus completing the automatic demolding work and eliminating the need for manual demolding.

[0029] After the workpiece is removed, the electric hydraulic push rod 12 is retracted, which drives the connecting plate 13 and the limit frame 14 to move downward. Under the action of the second spring 11, the lifting plate 8 is pulled downward, so that the push rod 9 moves downward and disengages from the lower mold cavity, so that the surface of the lower mold plate 1 returns to the lower mold cavity, which facilitates the subsequent injection molding work.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
