Description

Technical Field

[0001] The utility model belongs to the technical field of presses, and in particular relates to a continuous molding press. Background Art

[0002] The upper and lower supports of the existing molding machine are welded into one by columns. A set of molds needs to be equipped with a press. When the product specifications are changed, the molds need to be replaced at the same time, which is inefficient, labor-intensive, wastes a lot of man-hours, and has high equipment investment and use costs.

[0003] For example, the Chinese utility model patent with authorization announcement number CN 201261269Y discloses a horizontal continuous molding hollow plate punching machine, which can only be used for molds of the same specification, so its adaptability is poor. When the mold is replaced, the punching machine needs to be adjusted at the same time, resulting in reduced work efficiency and high equipment investment and use costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a continuous molding press.

[0005] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0006] A continuous molding press comprises a press travel mechanism and a mold mechanism. The press travel mechanism comprises an outer frame, an upper support arranged at the lower end of the outer frame, a pressure piece arranged at the lower end of the upper support, and a column opening and closing piece. The two ends of the upper support are hinged with columns, the fixed end of the column opening and closing piece is hinged on the outer frame, and the protruding end is hingedly connected to the column, and the protruding end of the pressure piece is provided with a pressure plate.

[0007] Preferably, the press travel mechanism further comprises a lifting member, and each end of the pressing plate is hinged with a connecting arm, the protruding end of the lifting member is hingedly connected to the connecting arm, and the fixed end of the lifting member is connected to the outer wall of the pressure member.

[0008] Preferably, the bottom of the outer frame is provided with walking wheels for walking.

[0009] Preferably, the mold mechanism comprises a lower support, and a lower mold and an upper mold that cooperate with each other are arranged on the upper end of the lower support.

[0010] Preferably, the upper end of the column is hingedly connected to the two ends of the upper support through a pin.

[0011] Preferably, the columns are provided at least in two locations and are symmetrically arranged on both sides of the upper support.

[0012] Preferably, the lifting member is an oil cylinder or a gas cylinder.

[0013] Preferably, the column opening and closing member is an oil cylinder or a gas cylinder.

[0014] Preferably, the pressure member is an oil cylinder or a gas cylinder.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Each column has a column opening and closing piece, which controls the opening or closing of the column to achieve pressure concentration when pressurizing the mold;

[0017] 2. When the pressure-applying part is a two-way single-rod oil cylinder or air cylinder, the pressurization or release of the mold is achieved by extending and retracting the piston rod; when the pressure-applying part is a single-rod oil cylinder or air cylinder, after the piston rod of the pressure-applying part is extended, it is necessary to drive the piston rod of the pressure-applying part to retract through the lifting part to achieve the purpose of pressurizing other molds. The purpose of using a single-stroke oil cylinder or air cylinder as a pressure-applying part is to apply greater pressure to the mold, with high structural strength and avoid damage to the piston rod;

[0018] To sum up, when the press travel mechanism moves to the top of the first mold mechanism, the piston rod of the column opening and closing part retracts to drive the column to retract, the column hooks the lower part of the lower support, and the piston rod of the pressurizing part extends to drive the pressure plate to press down, quickly pressing the upper mold. After the set pressure is reached, the mold automatically locks the upper mold, and then the piston rod of the lifting part retracts to drive the pressure plate to rise, and the pressure plate thereby drives the piston rod of the pressurizing part to retract, and finally the press travel mechanism moves to the top of the next set of molds that need to be pressurized. Through a press travel mechanism, 8 to 10 sets of molds can be pressurized continuously, which improves production efficiency and reduces equipment investment, while saving labor costs and reducing use and maintenance costs.

[0023] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] like Figure 1-2As shown, a continuous molding press includes a press travel mechanism and a mold mechanism, wherein the press travel mechanism includes an outer frame 1, an upper support 10 arranged at the lower end of the outer frame 1, a pressure member 9 arranged at the lower end of the upper support 10, and a column opening and closing member 3, wherein both ends of the upper support 10 are hinged with columns 4, the fixed end of the column opening and closing member 3 is hinged on the outer frame 1, and the extended end is hingedly connected to the column 4, and a pressing plate 11 is arranged at the extended end of the pressure member 9. In this embodiment, the pressure member 9 is a single-rod oil cylinder or air cylinder with a two-way stroke, and the pressurization or release of the mold is achieved by extending and retracting the piston rod.

[0026] Embodiment 2:

[0027] A continuous molding press, which differs from Example 1 in that the press travel mechanism also includes a lifting member 2, and a connecting arm 12 is hinged at each end of the pressing plate 11, the protruding end of the lifting member 2 is hingedly connected to the connecting arm 12, and the fixed end of the lifting member 2 is connected to the outer wall of the pressure member 9.

[0028] In this embodiment, the pressure member 9 is a single-stroke single-rod oil cylinder or air cylinder. When the piston rod of the pressure member 9 is extended, the piston rod of the pressure member 9 needs to be retracted through the lifting member 2 to achieve the purpose of pressurizing other molds. The purpose of using the pressure member 9 as a single-stroke oil cylinder or air cylinder is to apply greater pressure to the mold, with high structural strength, while avoiding damage to the piston rod.

[0029] Furthermore, the bottom of the outer frame 1 is provided with walking wheels 5 for walking, and the walking mechanism of the press can be moved to another mold through the walking wheels 5 at the bottom.

[0030] Furthermore, the mold mechanism includes a lower support 6, and a lower mold 7 and an upper mold 8 that cooperate with each other are arranged at the upper end of the lower support 6; the upper end of the column 4 is hingedly connected to the two ends of the upper support 10 through a pin shaft, and at the same time, the column 4 is arranged at least two places, and is symmetrically arranged on both sides of the upper support 10; when the press travel mechanism is moving, the column 4 is in an open state, and before pressurizing the mold, the column 4 is closed first, and the lower head is hooked on the bottom of the rib plate of the lower support 6.

[0031] Furthermore, the lifting member 2 is an oil cylinder or an air cylinder; the column opening and closing member 3 is an oil cylinder or an air cylinder.

[0032] The working principle of the utility model is:

[0033] When the press travel mechanism moves to the top of the first mold mechanism, the piston rod of the column opening and closing member 3 retracts to drive the column 4 to retract. Figure 3As shown, the column 4 is then used to hook the lower part of the lower support 6, and the piston rod of the pressure member 9 is extended to drive the pressure plate 11 to press down, quickly pressing the upper mold 8. After the set pressure is reached, the mold automatically locks the upper mold, and then the piston rod of the lifting member 2 is retracted to drive the pressure plate 11 to rise, and the pressure plate 11 thereby drives the piston rod of the pressure member 9 to retract, and finally the press travel mechanism moves to the top of the next set of molds that need to be pressurized. Multiple mold mechanisms can be pressurized through one press travel mechanism, which saves labor costs, has less equipment investment, and has low use and maintenance costs.
