Description

Vacuum heat transfer printing die Cross Reference to Related Applications The present application claims priority from chinese application filed at 25 of 4/2025 under application number CN 2025105397311 entitled "vacuum thermal transfer machine, die and its suit, wiring mechanism, mask and method", the disclosure of which is considered a part of the present disclosure and is incorporated herein by reference in its entirety. Technical Field The application belongs to the technical field of vacuum thermal transfer equipment, and particularly relates to a vacuum thermal transfer mold with adjustable lateral dimension. Background The vacuum heat transfer machine is processing equipment for realizing pattern transfer through the synergistic effect of hot pressing and negative pressure, and mainly comprises a machine body with a transfer cavity and a cover body capable of being opened and closed. In the operation flow, the object to be transferred (such as a mobile phone shell) is sleeved on the die in the transfer cavity, and then the transfer film material with the pattern is covered on the transfer cavity. When the cover body is closed, the equipment vacuumizes the transfer printing cavity through the vacuumizing system, so that the film material tightly wraps the transferred material, and meanwhile, the heat of the cavity is utilized to complete pattern transfer. However, the existing die for thermal transfer printing generally adopts a fixed integral structure, and the lateral dimensions such as the length and the width of the die cannot be adjusted, so that the adaptability of equipment is insufficient, and when the thermal transfer printing is performed on the transferred objects with different specifications, a user needs to purchase the dies with different specifications additionally, so that the use cost is increased. Disclosure of Invention The application aims to overcome the defect that the lateral dimension of the existing die for thermal transfer printing cannot be fixed and adjusted, and provides a vacuum thermal transfer printing die which consists of a body and a movable adjusting part, so that the lateral dimension of the vacuum thermal transfer printing die is changed by controlling the adjusting part to adapt to loading of transferred objects with different specifications.

In addition, by filling the filling member between the body and the regulating members and between the adjacent two regulating members, the gap can be blocked and a supporting effect can be provided for the transferred object, so that negative pressure is prevented from directly adsorbing the transferred object through the gap. Further, the bottom of the body and the bottom of the regulating member are respectively configured with an air inlet channel formed with an air inlet at the side of the transfer mold, and the lower side of the air inlet channel is opened, w
