Description

Technical Field

[0001] This utility model relates to the field of high-frequency equipment technology, specifically a high-frequency hinged shielding cover. Background Technology

[0002] In the process of pressing products using high-frequency equipment, effective control and shielding of high-frequency energy are crucial. As a type of high-frequency electromagnetic wave, if high-frequency waves diffuse outwards during the pressing process, they can not only interfere with surrounding equipment but also pose a potential threat to the health of workers. Therefore, during the pressing process, a shielding cover is typically used to cover the high-frequency upper mold to prevent the leakage of high-frequency energy.

[0003] However, in existing technologies, this shielding operation often relies on manual labor. Specifically, after the high-frequency upper and lower molds are joined, workers need to manually place the shielding cover over the outside of the upper mold. This method is not only cumbersome but also inefficient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-frequency hinged shielding cover, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-frequency hinged shielding cover, comprising a working platform, a support arm, an electric cylinder, a high-frequency upper die head, a shielding cover, and a hinge. The support arm is fixedly installed on the upper part of the working platform, the electric cylinder is fixedly installed inside the support arm, the high-frequency upper die head is fixedly installed on the telescopic end of the electric cylinder, and the shielding cover is rotatably connected to the bottom of the support arm through the hinge and covers the outside of the high-frequency upper die head.

[0006] Furthermore, a high-frequency lower die head is fixedly installed inside the working platform, and the high-frequency lower die head is located directly below the high-frequency upper die head.

[0007] Furthermore, the upper part of the high-frequency upper mold head is equipped with a support foot, and the top of the support foot is rotatably connected to a roller, the top of the roller always abutting against the top of the inside of the shielding cover.

[0008] Furthermore, the top of the shielding cover has a clearance slot, the size of which is larger than the size of the high-frequency upper mold head.

[0009] Furthermore, a baffle is fixedly installed on the side of the high-frequency upper mold head. After the shielding cover is deflected to the horizontal, the baffle and the high-frequency upper mold head together block the clearance slot.

[0010] Furthermore, grounding wires are symmetrically connected between the shielding cover and the working platform.

[0011] This invention provides a high-frequency hinged shielding cover. Compared with the prior art, it has the following advantages:

[0012] This high-frequency hinged shielding cover, through its hinge connection and roller transition design, enables the shielding cover to automatically deflect and follow the movement during the pressing process, eliminating the need for manual operation and significantly improving production efficiency and safety.

[0020] 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.

[0021] Please see Figure 1-6This utility model provides a technical solution: a high-frequency hinged shielding cover, including a working platform 1, a support arm 2, an electric cylinder 3, a high-frequency upper mold head 31, a shielding cover 4, and a hinge 41. The support arm 2 is fixedly installed on the upper part of the working platform 1, the electric cylinder 3 is fixedly installed inside the support arm 2, the high-frequency upper mold head 31 is fixedly installed on the telescopic end of the electric cylinder 3, and the shielding cover 4 is rotatably connected to the bottom of the support arm 2 through the hinge 41, and the shielding cover 4 covers the outside of the high-frequency upper mold head 31. When the electric cylinder 3 drives the high-frequency upper mold head 31 to rise and fall, the high-frequency upper mold head 31 will drive the shielding cover 4 to deflect around the hinge 41 as the center.

[0022] Specifically, a high-frequency lower mold head 11 is fixedly installed inside the working platform 1. The high-frequency lower mold head 11 is located directly below the high-frequency upper mold head 31. The specific structure and principle of the high-frequency lower mold head 11 and the high-frequency upper mold head 31 are well-known technologies in the field and will not be described in detail here.

[0023] The upper part of the high-frequency upper mold head 31 is equipped with a support foot 32. The top of the support foot 32 is rotatably connected to a roller 33. The top of the roller 33 is always in contact with the inner top of the shielding cover 4. In this way, during the process of the shielding cover 4 being deflected by the roller 33, there is a transition, and it will not come into contact with the high-frequency upper mold head 31.

[0024] The top of the shielding cover 4 has a clearance slot 42, the size of which is larger than that of the high-frequency upper die head 31. This allows for sufficient space for the high-frequency upper die head 31 to move during the deflection of the shielding cover 4. A baffle 34 is fixedly installed on the side of the high-frequency upper die head 31. After the shielding cover 4 is deflected and placed horizontally, the baffle 34 and the high-frequency upper die head 31 can jointly block the clearance slot 42, thereby preventing the high frequency from spreading to the outside of the shielding cover 4 through the clearance slot 42 and the high-frequency upper die head 31 during the pressing of the product.

[0025] A grounding wire 43 is symmetrically connected between the shielding cover 4 and the working platform 1. The grounding wire 43 can effectively prevent the shielding cover 4 from becoming live, thereby avoiding the existence of safety hazards.

[0026] During operation, the product is placed on the high-frequency lower die head 11. After starting the machine, the electric cylinder 3 pushes the high-frequency upper die head 31 downward until the bottom surface of the high-frequency upper die head 31 is in contact with the upper surface of the high-frequency lower die head 11. During the downward movement, under the action of gravity, the shielding cover 4 will naturally deflect downward around the hinge 41 until the bottom edge of the shielding cover 4 is in contact with the upper surface of the work platform 1. After the product is pressed, the electric cylinder 3 drives the high-frequency upper die head 31 upward. During the upward movement, it simultaneously drives the shielding cover 4 to deflect upward around the hinge 41. During the deflection process, since the shielding cover 4 abuts against the roller 33 and the roller 33 can rotate, the transition is smooth. When the high-frequency upper die head 31 and the shielding cover 4 move to the highest point, the product can be removed. Throughout the entire process, the shielding cover 4 moves with the high-frequency upper die head 31. In other words, there is no need for manual operation of the shielding cover 4, saving unnecessary steps and increasing efficiency.
