Description

Technical Field

[0001] The utility model relates to the technical field of foam molding dies, in particular to a foam molding die with good sealing performance. Background Technique

[0002] Foam molding dies are widely used in the manufacture of various foam products, such as thermal insulation materials, packaging materials, and cushioning materials, etc. The sealing performance of foam molding dies is crucial for ensuring the molding quality and product performance.

[0003] However, after being used for a period of time, the current foam molding dies often have poor sealing performance due to wear. This problem of decreased sealing performance not only affects the shape and dimensional accuracy of the products, but also causes uneven density of the foam material, thereby affecting its service performance.

[0004] Based on this, those skilled in the art have proposed a foam molding die with good sealing performance. Content of the Utility Model

[0005] The utility model discloses a foam molding die with good sealing performance, aiming to solve the technical problems existing in the background technique.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A foam molding die with good sealing performance includes a bottom plate. Two optical rods are symmetrically and fixedly connected to the top of the bottom plate. A top plate is fixedly connected between the tops of the two optical rods. Fixed sleeves are fixedly connected to the outer sides of the optical rods. A fixing plate is fixedly connected between the bottoms of the fixed sleeves. An extrusion mechanism is arranged on the top of the fixing plate. The extrusion mechanism includes a connecting frame. A driving shaft is rotatably connected inside the connecting frame. A cam is fixedly connected to the outer side of the driving shaft. An upper slot is opened in the top plate. A first connecting rod is rotatably connected inside the upper slot. The bottom of the first connecting rod is rotatably connected to a rotating ear.

[0008] The rotation of the driving shaft can drive the cam to rotate, and the first connecting rod can provide a limit for the rotating ear.

[0009] In a preferred scheme, the extrusion mechanism further includes two sliding sleeves. Both of the two sliding sleeves are slidably connected inside the fixing plate. A moving rod is fixedly connected to the top of the sliding sleeve. A lower slot is opened inside the moving rod. A second connecting rod is rotatably connected inside the lower slot. The top of the second connecting rod is rotatably connected to the rotating ear.

[0010] The second connecting rod can provide a limit for the rotating ear. When the second connecting rod rotates, it can drive the sliding sleeve to descend through the second connecting rod.

[0011] In a preferred embodiment, the extrusion mechanism further includes a rotating shaft and a contact wheel. The rotating shaft is rotatably connected inside the connecting frame through a torsion spring. The rotating shaft is fixedly connected to the rotating ear, the contact wheel is rotatably connected to one side of the rotating ear, and the cam is in rolling connection with the contact wheel.

[0012] The cam contacts the contact wheel, so that the rotating ear has the power to rotate.

[0013] In a preferred embodiment, an upper mold is fixedly connected between the bottoms of the sliding sleeves and below the fixed plate, and a lower mold is fixedly connected to the top of the bottom plate.

[0014] The downward movement of the sliding sleeve can drive the upper mold to descend, so that the upper mold contacts the lower mold, thereby producing a sealing effect.

[0015] In a preferred embodiment, a driving motor is fixedly connected to one side of the connecting frame, and the output end of the driving motor is fixedly connected to the driving shaft.

[0016] The driving motor can drive the driving shaft to rotate.

[0017] A foam molding die with good sealing performance provided by the present invention has the following advantages:

[0018] In the present invention, the cam contacts the contact wheel, so that the rotating ear has the power to rotate. When the rotating ear rotates, the second connecting rod can move. Through the movement of the second connecting rod, the sliding sleeve can be driven to descend. The downward movement of the sliding sleeve can drive the upper mold to descend, so that the upper mold contacts the lower mold, thereby ensuring that the upper and lower molds can achieve a continuously enhanced sealing effect during use.
