Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foam molds, in particular to an adjustable foam mold. Background Technique
[0002] A foam mold is a plastic foaming mold. The foaming resin is directly filled into the mold, heated and melted to form a gas-liquid saturated solution. Through nucleation, a large number of tiny nuclei are formed, and the nuclei grow to form foam plastic parts. There are three common foaming methods: physical foaming method, chemical foaming method and mechanical foaming method. With the development of modern technology, the usage functions of foam molds are gradually increasing, enabling them to better meet the requirements of foam molding during use.
[0003] When processing a foam mold, if different sizes of the same-shaped foam mold are to be produced, the size of an ordinary foam production mold cannot be adjusted, and only molds of different specifications can be used for processing and forming. This operation method increases the production cost and thus reduces the practicality of the device. Content of the Utility Model
[0004] In order to solve the above problems, the purpose of the utility model is to provide an adjustable foam mold to solve the problems mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model proposes an adjustable foam mold, including a mold body. An adjustable-size forming mechanism is arranged at the upper end of the mold body. The adjustable-size forming mechanism includes a mounting base fixed on one side of the top end of the mold body. A hydraulic rod is fixedly arranged on one side of the mounting base. A sealing gasket is fixedly arranged at one end of the hydraulic rod. An extrusion sheet is fixedly arranged on one side of the sealing gasket, and the outer wall of the extrusion sheet is inserted into the inner wall of the mold body. A screw rod is inserted through one side of the mold body, and the outer wall of the screw rod is threadedly connected to the inner wall of the mold body. A support plate is slidably arranged on the inner wall of the mold body, and one end of the screw rod is rotatably connected to one side of the support plate.
[0006] In one example, a clamping shaft is fixedly arranged at the other end of the screw rod, and a feeding groove is opened on the other side of the top end of the mold body.
[0007] In one example, a protective cover is hingedly arranged on one side of the inner wall of the feeding groove. A fixed handle is fixedly arranged on one side of the protective cover. A rotating handle is sleeved on the outer wall of the clamping shaft.
[0008] In one example, a sliding groove is opened on the top end of the mold body on the side of the feeding groove. Limiting grooves are opened on both sides of the inner wall of the sliding groove.
[0009] In one example, a moving bracket is slidably arranged on the inner wall of the chute, and the outer walls at both ends of the moving bracket are respectively slidably connected to the inner walls of the two limiting grooves. A roller is rotatably arranged at one end of the moving bracket, and the outer wall of the roller is in contact with one side of the protective cover.
[0010] The adjustable foam mold proposed by the present utility model can bring the following beneficial effects:
[0011] For this adjustable foam mold, by providing a mold forming structure with adjustable dimensions composed of a hydraulic rod, a sealing gasket, an extrusion sheet, a screw rod, a support plate, a clamping shaft, a feed slot, and a rotating handle, etc. When in use, foam material is injected through the feed slot, and then the protective cover is clamped in the feed slot through the fixed handle and fixed by the clamping structure. Then, the hydraulic rod is started to make the sealing gasket drive the extrusion sheet to extrude inside the mold body to form it. When the size of the formed shape needs to be adjusted, the rotating handle on one side is rotated to make the screw rod move in the mold body, thereby pushing the support plate to move therein, reducing or expanding the space inside the mold body. Such an operation enables the size of the finally formed foam mold to be adjusted, and there is no need to use other specifications of forming molds, thus improving the practicality of the device.
[0012] For this adjustable foam mold, by providing a movable clamping structure composed of a chute, a limiting groove, a moving bracket, and a roller, etc. After injecting the foam material and closing the protective cover, the moving bracket is slid in the chute to make the roller roll and press on the upper end of the protective cover.
