Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic cylindrical product forming molds, and in particular to a glass fiber reinforced plastic cylindrical product forming mold and a method. Background Art

[0002] Glass fiber reinforced plastics, also known as GFRP, is fiber reinforced plastic. It generally refers to reinforced plastics with unsaturated polyester, epoxy resin and phenolic resin matrices reinforced with glass fiber. Glass fiber or its products are used as reinforcing materials. They are called glass fiber reinforced plastics, or glass fiber reinforced plastics. Unlike tempered glass, cylindrical glass fiber reinforced plastics need to be formed using molding molds during the production process.

[0003] During the use of existing molding molds, after the molten material is poured into the mold, there may be gaps in the molten material after entering the molding mold. The existence of the gaps reduces the overall strength and hardness of the molded fiberglass. The existing molding molds cannot eliminate this hidden danger during use, thereby reducing the use value of the molding molds. Summary of the invention

At this time, the hydraulic cylinder is adjusted to drive the sealing round block to separate from the feeding hole, and the molten liquid stored in the filling frame is introduced into the mold body through each feeding hole to achieve secondary filling, thereby ensuring the excellent quality of the glass fiber reinforced plastic formed by casting.

After the filling is completed, the driving motor is started, and the driving motor drives the sliding frame to rotate inside the limiting ring rail, and then drives each vibration ball to knock the outer side of the mold body, so that the mold body is in a vibration state, accelerating the extrusion and accumulation of the liquid inside the mold body;

[0020] Step 2: After the rotating oscillating assembly works for a period of time, the height of the molten liquid inside the mold body drops, and the hydraulic cylinder is adjusted to drive the sealing round block to separate from the feeding hole, and the molten liquid stored in the filling frame is introduced into the mold body through each feeding hole to achieve secondary filling;

After cooling and molding, the casting mechanism takes the filling assembly away, and the second hydraulic cylinder is adjusted to drive the pressure block to separate from the side block. The connecting spring rod in the compressed state begins to reset, and the connecting spring rod drives the lower end blocking ring and the middle filling column to rise. The lower end blocking ring gradually pushes the cast fiberglass out of the mold body, and the staff collects it and ends the operation.

[0022] From the above, it can be seen that the present invention provides a FRP cylindrical product forming mold. Before casting the FRP cylindrical product, the casting mechanism drives the filling component to move to the top of the mold body and contact it, and then introduces the molten liquid into the mold body through the filling component. After the filling is completed, the driving motor is started, and the driving motor drives the sliding frame to rotate inside the limiting ring rail, and then drives each vibration ball to knock on the outside of the mold body, so that the mold body is in an oscillating state, accelerating the extrusion and accumulation of the liquid inside the mold body, making the molten liquid accumulate more densely, thereby improving the overall strength of the FRP formed by casting and the technical effect of the impact.
