Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a double-station entry and exit platform mold cavity vacuum machine. Background Art

[0002] In the vacuum pressing of FPC flexible circuit production, as well as mechanical equipment such as aerogel insulation pad thermal packaging pressing, there is an important process step, which is high-temperature vacuum pressing. This process link is to place the product on the high-temperature vacuum lower fixture set by the equipment, and then press the upper fixture from top to bottom to combine with the lower fixture to form a sealed cavity. At the same time, the product is also subjected to the pressing effect. In this process, when the upper and lower fixtures are combined, the equipment begins to vacuum the sealed cavity. Under the action of vacuum, the air inside the product will be completely sucked out to ensure product quality.

[0003] However, in traditional equipment, when the upper and lower fixtures are closed, the product will also be squeezed. When vacuuming, part of the air inside the product will be locked in the local sealed space formed by the upper and lower fixtures squeezing the product, resulting in incomplete vacuuming in the center of the product and a relatively high product defect rate.

[0004] To this end, the prior art (announcement number: CN218579865U, announcement date: 2023.03.07) discloses a one-time vacuum hot-pressing formed thermal insulation pad structure. By improving the structure of the thermal insulation pad, the hot melt adhesive and the aerogel core material are not completely adhered when vacuuming, so the air can be effectively discharged and the vacuum defect can be reduced. However, the existing hot-pressing vacuum equipment generally performs vacuuming while hot-pressing. The product will still be pressed during vacuuming, and there is still the undesirable phenomenon of incomplete vacuuming. In addition, the existing related equipment can only hot-press one product at a time. After opening the jig, not only does it need to disassemble the hot-pressed product, but it also needs to reinstall the product to be hot-pressed, resulting in very low production efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0006] A double-station entry-exit platform mold cavity vacuum machine includes a frame, an upper jig assembly and a lower jig assembly are arranged in the frame, the upper jig assembly is located above the lower jig assembly, and a pressing cylinder assembly is fixedly installed on the top side of the frame;

[0007] The upper fixture assembly includes a vacuum chamber, a sealing seat, a pressing connector and an upper fixture plate. The pressing connector is fixedly mounted above the upper fixture plate. The upper fixture plate is installed in the vacuum chamber with a clearance fit. The sealing seat is fixedly mounted on the top side of the vacuum chamber. The upper end of the pressing connector is slidably fitted in the sealing seat. The pressing cylinder assembly drives the pressing connector to move up and down. The bottom side edge of the vacuum chamber is lower than the bottom side surface of the upper fixture plate.

[0008] The lower jig assembly includes a sliding seat and a lower jig plate. The lower jig plate is fixedly mounted on the sliding seat. A sealing groove is formed at the upper edge of the sliding seat. A sealing ring is installed in the sealing groove in a gap-fitting manner. The sealing ring is located on the outer side of the lower jig plate. When the upper jig assembly is pressed downward, the bottom edge of the vacuum chamber is pressed on the sealing ring.

[0009] Furthermore: entry and exit windows are formed on both sides of the frame, at least two horizontal brackets are fixedly installed in the frame, and the left and right ends of the horizontal brackets extend out of the entry and exit windows. A guide rail is fixedly installed on the horizontal bracket, and two entry and exit station assemblies are slidably installed on the guide rails. Two lower fixture assemblies are provided, and the sliding seats of the lower fixture assemblies are fixedly installed on the entry and exit station assemblies one by one.

[0010] Furthermore: two driving mechanisms are fixedly installed on one of the transverse brackets, and the driving mechanisms drive the entry and exit station assemblies to move left and right on the guide rail in a one-to-one correspondence.

[0011] Further: the driving mechanism includes a rack, a gear and a conveying motor, the rack is fixedly mounted on the bottom side of the entry and exit station assembly, the conveying motor is fixedly mounted on the transverse bracket, the gear is fixedly mounted on the rotor of the conveying motor, and the gear and the rack are meshed with each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When the pressing cylinder assembly drives the upper fixture assembly to press downward, since the bottom edge of the vacuum chamber is lower than the bottom side of the upper fixture plate, the bottom edge of the vacuum chamber will first contact the sealing ring of the lower fixture assembly. At this time, the vacuum chamber is evacuated. During the evacuation, the bottom edge of the vacuum chamber can press the sealing ring to achieve sealing in the vacuum chamber.

[0016] 2. After the vacuum is completed, the pressing cylinder assembly continues to press down. Since the upper end of the pressing connector is slidably fitted in the sealing seat, it can drive the upper fixture plate to press on the lower fixture plate.

[0017] The utility model does not squeeze the surface of the product when vacuuming the product, and does not produce any bubbles during pressing. Therefore, the pressing effect of the product can be guaranteed, incomplete vacuuming will not occur, and the yield rate is greatly improved.
