The present invention relates to a compression molding apparatus in which at least one projector projects plural positioning images on a carrying platform so that each positioning image is adapted for fixing each of the plural connecting pieces on a carrying platform, such that the each connecting piece is stacked on the carrying platform based on the each positioning image quickly and accurately.
A conventional compression molding apparatus is disclosed in TW Publication No. M420424, wherein in operation, plural thermoplastic materials are cut into desired shapes and stacked on a carrying platform, and the carrying platform moves toward below a pressing mold, wherein a driving cylinder drives the pressing mold to move downwardly and to press the plural thermoplastic materials on the carrying platform, and a heater on a top of the pressing mold heats the plural thermoplastic materials, thereby molding the plural thermoplastic materials.
However, it is time-consuming for a worker to feed and stack the plural thermoplastic materials on the carrying platform. Also, the plural thermoplastic materials cannot be fixed on the carrying platform accurately.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a compression molding apparatus in which at least one projector projects plural positioning images on a carrying platform so that each positioning image is adapted for fixing each of the plural connecting pieces on a carrying platform, such that the each connecting piece is stacked on the carrying platform based on the each positioning image quickly and accurately.
To obtain the above objective, a compression molding apparatus provided by the present invention contains:
When the carrying platform is located in the material feeding zone, plural connecting pieces of different shapes are stacked on the carrying platform in turn.
Each connecting piece is stacked on the carrying platform by aligning with each positioning image.
When the carrying platform moves into the molding zone, the pressing mold moves downwardly to press the each connecting piece on the carrying platform.
With reference to
The base 10 includes a material feeding zone 11 and a molding zone 12.
The carrying platform 20 moves into the molding zone 12 from the material feeding zone 11, and when the carrying platform 20 is located in the material feeding zone 11, plural connecting pieces 70 of different shapes are stacked on the carrying platform 20 in turn. In this embodiment, each connecting piece 70 is any one of thermoplastic material, cloth, leather, and a combination of the thermoplastic material, the cloth, and the leather. The carrying platform 20 includes three-dimensional patterns formed thereon, and the thermoplastic material has a temperature resistant layer formed on a first surface thereof and has a low temperature layer formed on a second surface thereof, wherein the temperature resistant layer is made of a mixture of thermoplastic polymeric material and colorant by using an extruder, and the thermoplastic polymeric material is selected from a group consisting of thermoplastic polyurethane (TPU)+styrene butadiene rubber (SBR), thermoplastic polyurethane (TPU)+(styrene ethylene butylene styrene (SEBS), thermoplastic polyurethane (TPU)+(thermoplastic rubber (TPR), thermoplastic polyurethane (TPU)+ethylene propylene diene monomer (EPDM), thermoplastic polyurethane (TPU)+thermoplastic polyurethane (TPU) hot melt adhesives, and thermoplastic polyurethane (TPU)+nylon elastomer. Preferably, a color is printed, coated or surface sandwiched on the temperature resistant layer. The leather is any one of artificial leather (such as PU, TPU, TPO or TPE leather), natural leather (such as cattle leather, sheep leather or swine leather) and synthetic leather (i.e., a combination of natural lather and artificial leather).
The projector 30 is fixed above the material feeding zone 11 so as to project plural positioning images 31 on the carrying platform 20, wherein the each connecting piece 70 is stacked on the carrying platform 20 by aligning with the each positioning image 31. In this embodiment, the projector 30 is electrically connected with a controller 32 (such as a control center, a console, or a computer), wherein the controller 32 inputs the positioning image 31 projected by the projector 30 and sets a playing time and a display sequence of the each positioning image 31, and the each positioning image 31 is a pattern or a reference location of the each connecting piece 70 on the carrying platform 20.
The pressing mold 40 is arranged above the molding zone 12, when the carrying platform 20 moves into the molding zone 12, the pressing mold 40 moves downwardly to press the each connecting piece 70 on the carrying platform 20. In this embodiment, the pressing mold 40 includes three-three-dimensional patterns formed on a bottom thereof.
The heater 50 is mounted on a top of the pressing mold 40, wherein when the pressing mold 40 presses the each connecting piece 70 on the carrying platform 20, the heater 50 heats the each connecting piece 70. Alternatively, the heater 50 can be mounted on a bottom of the carrying platform 20.
The lifting mechanism 60 is secured above the molding zone 12 so as to drive the pressing mold 40 to move upwardly or downwardly, such that the pressing mold 40 moves onto or away from the carrying platform 20.
