An electrical heating high light injection mold of isolation energy-saving structure

Abstract

The invention discloses an electrical heating high light injection mold of isolation energy-saving structure, including a mould cavity inlay block (1), a core inlay block (2), an insulation board (3), a fixed template (4), a movable template (5 ), a heating channel (6), and a cooling channel (7). The invention adopts an energy saving technology of fixing the mould cavity inlay block and the core inlay block in the fixed template and the movable template, and using the insulation board to obstruct the heat from dissipation to the entire mold, so that the large stationary type energy consumption and narrow clutch type adaptability in the electric heating high light injection mold in the prior art is overcome, and the provided electrical heating high light injection mold of isolation energy-saving structure can save more than 50% of energies compared with the stationary type of the prior art; a structure mode of fixing the inlay block spacer insulating board in the template, facilitating to continue to use the layout structure of core pumping, ejecting, stripping agencies of the ordinary injection mold to design the electric heating high light injection mold, which is beneficial to the adaptability spreading of the electric heating high light injection mold, facilitates the popularize promulgation and achieves the object of producing energy-saving, balanced temperature improvement and wide adaptability electric heating high light injection mold.

Description

technical field [0001] The invention relates to a high-gloss injection mold, in particular to an electric-heating high-gloss injection mold with a heat-insulating and energy-saving structure that uses a heat shield to isolate the cavity and core insert of the electric-heating high-gloss injection mold from a fixed template and a movable template. Background technique [0002] The high-gloss no-melt mark injection molding system technology based on the theory of balanced speed heating and speed cooling mold cavity is a new technology developed in recent years. The high-gloss injection mold has a unique laminated structure of equidistant thin shell cavities. It is different from ordinary injection molds. High-gloss injection molds are divided into electric heating, steam heating, and water heating according to heating methods. This article only involves electric heating high-gloss injection molds. Electrothermal high-gloss injection molds in the prior art are divided into fix...

Problems solved by technology

[0003] In the application, due to the heat transfer effect of the fixed electrothermal high-gloss injection mold, the original intention is to heat the cavity plate and the core plate, but actually the whole mold is heated by the heat transfer of the fixed laminate, in order to quickly heat the cavity and core wall To reach the melting temperature of the plastic, it is necessary to increase the heating power; in addition, the thickness of each part of the actual mold is inconsistent, even if the heating power is increased, the heating temperature rise of each part of the cavity plate and core plate is difficult to balance, It is easy to cause poor color difference on the surface of the product due to the temperature difference of the mold cavity. Therefore, there are problems such as large energy consumption, low heat energy utilization rate, and unbalanced temperature rise. Injection molding molds for flat-plate plastic products with simple demoulding and core-pulling mechanisms. At the same time, the thickness of the cavity plate and core plate is also limited, lacking the necessary wall thickness to balance the temperature rise of the profile surface, and the holes with electric heating pipes If it is too close to the surface of the cavity or core, the temperature difference in the shape of a grid stripe will be reflected on the surface, and it is also easy to cause poor color difference on the surface of the product due to the temperature difference on the surface. Therefore, there are limitations in adaptability and surface The problem of uneven temperature rise

Therefore, the electrothermal high-gloss injection mold of the prior art has the problems and deficiencies of large energy consumption, low utilization rate of heat energy, unbalanced temperature rise, and limited adaptability
