Technical Field

[0001] This invention relates to the field of molding medical carbon fiber bed boards, and particularly to a net-size molding equipment and process for medical carbon fiber bed boards. Background Technology

[0002] Medical bed boards are an important component of medical equipment. They come in various materials and types and must meet specific requirements in terms of design, function, and use. Common material types include cold-rolled steel plate, carbon fiber, glass fiber, and ABS plastic.

[0003] The existing medical carbon fiber bed board process mostly involves laying and cutting pre-prepared carbon fiber sheets to form a preform with a general product shape. After entering the mold, it is pressed and cured. Since the shape and size cannot be fixed, the product needs to be reshaped to reach the shipping size.

[0004] Therefore, it is necessary to propose a net-size forming equipment and process for medical carbon fiber bed boards to solve the above problems. Summary of the Invention

A first fixed rod is installed in the inner cavity of the first movable groove, and a first spring is wound around the outer wall of the first fixed rod.

[0009] Preferably, one side of the first spring is installed in the inner cavity of the first movable groove, and the other side of the first spring is connected to the locking block. The two ends of the locking block are movably connected in the inner cavity of the first movable groove and sleeved on the outer wall of the first fixed rod. The locking block is inserted into the inner cavity on the side of the upper mold.

[0010] Preferably, the outer wall of the sealing assembly is symmetrically provided with buffer grooves around its perimeter, and the inner cavity of the buffer groove is symmetrically provided with second movable grooves at both ends. A second fixed rod is installed in the inner cavity of the second movable groove, and a second spring is wound around the outer wall of the second fixed rod.

[0012] Preferably, the demolding assembly is a belt, which is rotatably connected to the inner cavity at the bottom of the lower mold. The top of the demolding assembly extends to the bottom of the inner cavity of the lower mold. A lead screw is rotatably connected to one end of the inner cavity of the lower mold. A servo motor is installed on the outer wall of the lower mold, and the servo motor is connected to the lead screw through a first rotating shaft.

[0013] Preferably, a rotary motor is installed at one end of the movable seat, the rotary motor is linearly and movably connected to the inner cavity of the lower mold, the rotary motor is connected to the cam component through a second rotating shaft, and the other end of the movable seat is movably connected to the inner cavity of the lower mold and threadedly connected to a lead screw.

[0014] Preferably, a rotary motor is installed at one corner of the base, and the rotary motor is connected to the rotating shaft through a coupling. A hydraulic push rod is installed at the center of the top of the top plate, and the bottom of the hydraulic push rod is installed on the top of the upper mold. A roller seat is installed at the bottom of the hydraulic lifting rod, and the bottom of the roller seat is attached to the top of the base. There are three hydraulic lifting rods.

[0015] A net-size molding process for medical carbon fiber bed boards includes the following steps: S1: The prefabricated body, roughly shaped like a medical carbon fiber bed board, is assembled by laying and cutting carbon fiber prepreg sheets. It is then placed in the inner cavity of the lower mold, and the hydraulic push rod is activated to drive the upper mold to press down, thereby pressing the prefabricated body. S2: When the upper mold and the lower mold are attached, the bottom of the upper mold will contact the inclined surface of the top of the card block. Based on this, it can be squeezed into the inner cavity of the sealing component. When the upper mold and the lower mold are completely attached, the card block can be pushed into the inner cavity of the upper mold by the first spring. Start the air pump to inflate the airbag. At this time, the airbag can seal the attachment point of the upper mold and the lower mold. S3: When the upper mold moves, it will simultaneously drive the buffer component to press down.

The card block is manually reset, the hydraulic push rod is started, the upper mold is lifted, the rotary motor is started, the top plate is rotated, and the hydraulic lifting rod is started until the roller seat contacts the ground, thereby supporting the top plate. S5: Rotate the cam component to make it contact the top of the demolding assembly, thereby demolding the medical carbon fiber bed board. While the cam component is rotating, the servo motor is started, so that the outer wall of the movable seat can be connected to the lead screw thread. Based on this, the cam component is driven to move laterally, completing the all-round demolding process of the bottom of the medical carbon fiber bed board.

[0016] Compared with the prior art, the present invention provides a net-size molding device and process for medical carbon fiber bed boards, which has the following beneficial effects: 1. The net-size molding equipment and process for medical carbon fiber bed boards directly uses a lower mold and an upper mold that are consistent with the finished product specifications. The cut prepreg sheets are laid inside the lower mold and the cavity of the lower mold is filled. After filling the cavity of the lower mold, the product preform is consistent with the finished product size. After curing, the product can be demolded to obtain a product with the same size and shape as the finished product. This saves prepreg material in the molding process, reduces loss, and eliminates secondary processing in the later stages, saving labor and equipment processing time.

[0017] 2. The net-size molding equipment and process applied to medical carbon fiber bed boards, through the setting of airbags and clamping blocks, can seal the contact area between the lower mold and the upper mold during the molding process, thereby improving the quality of the subsequent finished products and reducing the generation of defective products. Through the setting of buffer blocks and buffer components, when the upper mold is pressed down, it can drive the buffer components to press down, so that the buffer components can cooperate with the buffer blocks to buffer the upper mold.

[0018] 3. The net-size molding equipment and process for medical carbon fiber bed boards can lift the top of the demolding component through a rotatable and laterally movable cam component, so that demolding can be carried out quickly after molding is completed. Attached Figure Description

The upper mold 9 and the lower mold 7 are fitted together, with the airbag 12 located at the fitting point of the upper mold 9 and the lower mold 7. The tops of the two locking blocks 18 are inclined on opposite sides. First movable grooves 19 are symmetrically opened at both ends of both sides of the sealing assembly 11, and a first fixing rod 20 is installed in the inner cavity of the first movable groove 19. A first spring 21 is wound around the outer wall of the first fixing rod 20. One side of the first spring 21 is installed in the inner cavity of the first movable groove 19, and the other side of the first spring 21 is connected to the locking block 18. The two ends of the locking block 18 are movably connected in the inner cavity of the first movable groove 19 and sleeved on the outer wall of the first fixed rod 20.

S3: When the upper mold 9 moves, it will simultaneously drive the buffer 10 to press down. At this time, it can enter the inner cavity of the buffer groove 22 and contact the buffer block 26. At this time, the upper mold 9 can perform buffering work through the second spring 25. S4: After the preform is pressed, the net size forming process of the medical carbon fiber bed board can be completed. The card block 18 is manually reset, the hydraulic push rod 4 is started, the upper mold 9 is lifted, the rotary motor 2 is started, the top plate 3 is rotated, and the hydraulic lifting rod 6 is started until the roller seat 5 contacts the ground, thereby supporting the top plate 3.
