Description

Technical Field

[0001] This utility model relates to a pressing device, and more particularly to a servo pressing device and a composite molding machine. Background Technology

[0002] In the production process of composite molding machines, after the material is formed and cooled, it needs to be traction and conveyed. Currently, tracked traction is commonly used. For example, Chinese patent CN212764881U discloses a glass fiber pultruded pipe traction device, which includes a guide rail, a frame that moves along the guide rail, and a control system. The frame is equipped with an upper traction mechanism and a lower traction mechanism. The upper traction mechanism has an upper track, and the lower traction mechanism has a lower track. The upper and lower tracks clamp and traction the pipe. The control system includes a PLC controller, a pipe diameter measuring instrument, a frame power mechanism, and a track power mechanism. However, tracked traction equipment, including the above-mentioned traction device, has the following disadvantages:

[0003] 1. Track wear: The high hardness of glass fiber composite materials can easily cause accelerated track wear, reduce track life, and require frequent replacement.

[0004] 2. Uneven traction force: Due to the special properties of glass fiber composite materials, the track may not be able to apply force evenly during traction, resulting in uneven product size or shape changes.

[0005] 3. Difficult to clean: During the cutting and extrusion process of glass fiber composite materials, debris and dust are generated, which easily adhere to the track, increasing the difficulty of cleaning.

[0006] 4. Material applicability limitations: Some brittle or high-viscosity glass fiber composite materials may not have good contact with the track, resulting in traction difficulties or instability.

[0007] 5. Complex adjustment: Using tracked traction requires track adjustment and alignment to ensure proper friction, which requires experienced operators, increasing the difficulty of operation and time costs. Utility Model Content

[0008] The purpose of this invention is to provide a servo-driven pressing device and a composite molding machine. Through the design of the upper and lower pressing dies and the combination of the lateral movement drive mechanism, the product after molding and cooling can be pressed. Since the surfaces of the upper and lower pressing dies are flat, they can provide balanced pressure, which can ensure that the composite material is uniformly compacted and tightly bonded during the molding process, thereby improving the quality and performance of the product.

[0009] The objective of this utility model can be achieved through the following technical solutions:

[0038] A servo-driven pressing device is used in a composite molding machine, such as... Figure 1 As shown, it includes:

[0039] The fixed frame 6, the pressing mechanism 1, and the upper pressing mold 4 and the lower pressing mold 5 provided on the fixed frame 6. Under the action of the pressing mechanism 1, the upper pressing mold 4 moves toward the lower pressing mold 5 to clamp the product located between the upper pressing mold 4 and the lower pressing mold 5.

[0040] The lateral movement drive mechanism includes a first motor 7, a first transmission mechanism, a lateral lead screw 10, and a connecting block 9. The first motor 7 is connected to the lateral lead screw 10 through the first transmission mechanism and drives the lateral lead screw to rotate. One end of the lateral lead screw is fixed by a bearing, and the other end is connected to the connecting block 9 by a bearing. The connecting block is fixed to the bottom of the fixed frame 6.

[0041] Through the design of the upper die 4 and the lower die 5, combined with the lateral movement drive mechanism, the product after molding and cooling can be pressed. Since the surfaces of the upper die 4 and the lower die 5 are flat, they can provide balanced pressure, which can ensure that the composite material is uniformly compacted and tightly bonded during the molding process, thereby improving the quality and performance of the product.

[0042] The elimination of tracks reduces the accumulation of debris and dust, as well as the need for cleaning. It also reduces track wear and replacement, lowering equipment maintenance costs.

The annular partition plate 6-5 is located between the first annular side plate 6-1 and the second annular side plate 6-2, and is sleeved outside the axial base plate 6-3 and the axial mounting plate 6-4. The connecting block is fixed to the bottom of the axial base plate 6-3.

[0045] In this way, while enabling lateral passage, the annular partition 6-5 can solve the problem of easy disintegration caused by excessive length.

[0046] In addition, in this embodiment, the axial mounting plate 6-4 is provided with a plurality of guide modules 3, which pass through the axial mounting plate 6-4 and are connected to the upper surface of the upper pressure mold 4.

[0047] In this embodiment, the guide module 3 includes two first connectors, two guide sleeves, two guide posts, and a connecting plate. The two first connectors are fixed to the upper surface of the upper die 4 along the axis of the transverse screw 10. The two guide sleeves are fixed to the axial mounting plate 6-4 along the axis of the transverse screw 10. The axes of the two guide posts are vertically arranged, and one end is fixedly connected to the two first connectors respectively. The other end passes through the axial mounting plate 6-4 and then passes through the two guide sleeves respectively. The connecting plate connects the two guide posts to one end that passes through the guide sleeves.

[0048] The specially designed guide module 3, consisting of two guide rods in a set, works in conjunction with the guide sleeve to improve the stability of the guide and prevent tilting caused by different guide modules.

[0049] Furthermore, in this embodiment, there are two annular partition plates 6-5, and the pressing mechanism 1 is located between the two annular partition plates 6-5.

[0050] Furthermore, in this embodiment, a first pressure sensor 2 is provided above the upper pressure mold 4. The first pressure sensor 2 is used to detect the pressure applied by the lower pressure mechanism 1 to the upper pressure mold 4.

[0051] In some embodiments, the lateral movement drive mechanism also includes a slide rail 11, and the bottom of the fixed frame 6 is provided with a plurality of sliders 8 that cooperate with the slide rail 11.

[0052] In some embodiments, the first transmission mechanism is a worm gear transmission mechanism; in other embodiments, the first transmission mechanism is a synchronous belt pulley transmission mechanism. Those skilled in the art can select a suitable transmission mechanism according to specific needs.

[0053] In addition, a second pressure sensor for detecting lateral pressure is provided at the bottom of the fixed frame 6.

[0054] like Figure 2 and Figure 3 As shown, the device of this application operates in two states. When operating, the material to be composite molded is first prepared, which is usually a composite material made of resin and reinforcing material.

[0055] Then, the pressing mechanism 1 is activated, which clamps the upper pressing mold 4 and the lower pressing mold 5 together. It then drives the pressing device to perform the pressing operation. The direction and method of movement of the pressing device are determined according to the specific equipment design, and can be up and down, forward and backward, or other directions.
