Description

Technical Field

[0001] This utility model relates to the field of glass forming technology, and in particular to a compression-formed bridge mechanism. Background Technology

[0002] The molding process of a compression molding machine relies on a shift fork mechanism to gradually move the mold between the heating station, pressing station, and cooling station. The shift fork conveying structure synchronizes the movement of each fork, with the movement distance and direction of each fork being consistent. This shift fork structure is not only simple in structure but also has high conveying efficiency.

[0003] In actual compression molding, compression molding is generally carried out in a vacuum environment to prevent the lens products from oxidizing and generating gas entrapment defects. The lens molding station is generally equipped with a vacuum cover structure so that the lens is molded in a vacuum environment.

[0004] However, in this molding station structure, since the left and right stations are for heating and cooling respectively, the molding station needs to ensure sufficient distance from adjacent stations to prevent heat transfer and large temperature differences on both sides of the mold, and also ensure sufficient installation space for the vacuum cover. This results in a relatively large distance between the molding station and the stations on both sides. The shift fork station also makes it difficult to smoothly transfer the mold from other stations to the molding station. Therefore, existing molding stations generally require additional robotic arms for loading and unloading to assist in mold transfer. This structure results in low mold transfer efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a molded bridge mechanism.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The present invention discloses a compression molding bridge mechanism, which includes a fixed base and a molding station fixed on the fixed base; temperature control stations are provided on both sides of the molding station.

[0008] A bridging platform is provided between the temperature control station and the molding station; the bridging platform includes an upper fixed plate and a lower fixed plate fixed on a fixed base; a flip plate is rotatably connected to the upper fixed plate; a rotating module for driving the flip plate to rotate is provided on the fixed base; the rotating module is connected to the lower fixed plate.

[0009] Furthermore, the rotating module includes a telescopic component and a push rod; one end of the telescopic component is fixed to the lower fixed plate; the bottom of the flip plate is provided with a slot; a connecting shaft is hinged inside the slot; the other end of the telescopic component is hinged to the bottom of the connecting shaft.

[0010] Furthermore, the telescopic component is a cylinder.

[0011] Furthermore, the push rod is fitted with a guide sleeve; the guide sleeve is fixed on the fixed base; the inner hole of the guide sleeve matches the rod body of the push rod.

[0012] With the above structure, the beneficial effects of this utility model are as follows: When the product inside the mold needs to be molded at the molding station, the flip plate flips up and separates from the molding station, so that the vacuum cover has enough space to fit outside the molding station; when the mold needs to enter or exit the molding station, the rotating module drives the flip plate to rotate. When the flip plate rotates to a horizontal state, the top surface of the flip plate, the top surface of the worktable in the temperature control station, and the top surface of the worktable in the molding station are all on the same horizontal plane, which can ensure that the mold can be transferred from the temperature control station and the flip plate to the molding station in sequence, or the mold can be transferred from the molding station and the flip plate to the temperature control station in sequence, by means of the shift fork; the original shift fork structure is used directly to transfer the mold, and there is no need to pick up the mold, which improves the transfer efficiency of the mold between the molding station and the temperature control station.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown, the present invention discloses a compression molding bridge mechanism, which includes a fixed base 8 and a molding station 3 fixed on the fixed base 8; both sides of the molding station 3 are provided with temperature control stations 4; the temperature control stations 4 are used for heating or cooling the mold 1, and can heat the mold 1 to a specified temperature or cool the mold 1 to a specified temperature; the temperature control stations 4 are also fixed on the fixed base 8; as shown Figure 2 As shown, the arrow indicates the conveying direction of mold 1. The temperature control station 4 to the right of molding station 3 is the heating station, and the temperature control station 4 to the left of molding station 3 is the cooling station. Molding station 3, cooling station and heating station are not fundamentally different from existing technologies, so they will not be described in detail.

[0023] A bridging platform is provided between the temperature control station 4 and the molding station 3; the bridging platform includes an upper fixing plate 10 fixed on a fixing base 8 and a lower fixing plate 5 fixed on a fixing base 8; a flip plate 2 is rotatably connected to the upper fixing plate 10; a rotating module for driving the flip plate 2 to rotate is provided on the fixing base 8; the rotating module is connected to the lower fixing plate 5.

[0024] When the product in mold 1 needs to be molded at the molding station 3, the flip plate 2 flips up and separates from the molding station 3, so that the vacuum cover has enough space to fit outside the molding station 3.

[0025] When mold 1 needs to move in or out of molding station 3, the rotating module drives the flip plate 2 to rotate. When the flip plate 2 is rotated to a horizontal state, the top surface of the flip plate 2, the top surface of the worktable in temperature control station 4, and the top surface of the worktable in molding station 3 are all on the same horizontal plane. This ensures that mold 1 can be transferred from temperature control station 4 and flip plate 2 to molding station 3 in sequence, or from molding station 3 and flip plate 2 to temperature control station 4 in sequence, by means of the shift fork. The original shift fork structure is used to transfer mold 1 directly, and there is no need to pick up mold 1, which improves the transfer efficiency of mold 1 between molding station 3 and temperature control station 4.

[0026] In a preferred embodiment of this utility model, the rotating module includes a telescopic component 6 and a push rod 9; one end of the telescopic component 6 is fixed to the lower fixed plate 5; a slot 202 is provided at the bottom of the flip plate 2; a connecting shaft 201 is hinged inside the slot 202; the other end of the telescopic component 6 is hinged to the bottom of the connecting shaft 201; the slot 202 is used to limit the swing angle of the connecting shaft 201; during the rotation of the flip plate 2, the connecting shaft 201 rotates within the slot 202, so that the connection point between the push rod 9 and the connecting shaft 201 is always in the same vertical direction; the telescopic component 6 pushes the push rod 9, causing the flip plate 2 to rotate around the upper fixed plate 10, thereby realizing the rotation of the flip plate 2.

[0027] In a preferred embodiment of this utility model, the telescopic component 6 is a cylinder.

[0028] In a preferred embodiment of this utility model, the push rod 9 is covered with a guide sleeve 7; the guide sleeve 7 is fixed on the fixed base 8; the inner hole of the guide sleeve 7 matches the rod body of the push rod 9; under the guidance of the guide sleeve 7, the push rod 9 can move linearly along the height direction, the positioning angle of the flip plate 2 is more accurate, and the connection between the forming station 3 and the temperature control station 4 and the flip plate 2 is more stable.

[0029] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
