A kind of foil film thermal transfer printing equipment and using method

Abstract

The embodiment of the present invention discloses a foil film thermal transfer equipment and its use method. The foil film thermal transfer equipment includes a convex mold and a concave mold. A sprue sleeve is arranged on the upper surface of the convex mold, and The mold is provided with a punch core, and a gate adjustment assembly for adjusting the diameter of the gate and used to reduce the plastic flow rate is provided between the punch and the punch core, and the die is provided with a die core, There is an air extraction hole on the die core of the die, and the device is provided with a gate adjustment component. The user can turn the adjustment plate to adjust the diameter of the gate according to the actual situation, so that the speed of the plastic impacting on the foil film is small and the foil film The ink is blown on the film, resulting in bubbles in the pattern or poor transfer quality, and the gate adjustment component is also equipped with an auxiliary air guide sleeve. If the cavity volume is large, after the plastic enters, the auxiliary guide can be used The air sleeve accommodates the gas that is removed in time in the cavity, and at the same time, the auxiliary air guide sleeve can be used to assist in pushing out the workpiece after injection molding is completed.

Description

technical field [0001] The embodiment of the present invention relates to the field of heat transfer printing equipment, in particular to a foil film heat transfer printing equipment and a method for using it. Background technique [0002] Thermal transfer printing is to design the pattern first, then make the copper plate, and then engrave the pattern on the copper plate in different colors through the electric engraving machine, and then take the copper plate to the printing machine to print the pattern on the PET film, and then pass the heat transfer. The equipment transfers the pattern to the product. It is mainly used for plastics, EVA, and stainless steel. It is suitable for mass production. There are many types of heat transfer equipment, and the most important one is the transfer mold. The functional pattern is printed on the foil film by a high-precision printing machine, and the foil film is sent into the special molding mold by a high-precision foil feeding machin...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a foil heat transfer equipment and its use method to solve the problem in the prior art that when the equipment is in use, the foil film is directly pressed into the die, and then the high temperature is injected into the cavity. For high-pressure plastic, if the pattern on the foil film is large, when the molten high-pressure plastic is injected into the cavity, it will impact on the foil film at a relatively high speed. At this time, the ink on the transfer pattern is easily blown. This can cause problems with bubbles in the pattern or poor transfer quality
