Description

A mold heating structure

technical field

The utility model relates to a mold structure, in particular to a mold heating structure provided with a plurality of heating devices with heating pipe bodies to heat the mold.

Background technique

Plastics generally need to use molds when they are produced and molded. The main processing methods are injection molding, blow molding, and hot-pressing molding. It cools and solidifies into a plastic part. When the plastic is injected into the mold cavity of the male and female modules, the high-temperature molten material contacts the cooled mold cavity wall to form a thin solidified layer, and the temperature of the molten material near the wall is also high. Therefore, it will be reduced, which will affect the flow of plastic in the molten state, and it is prone to turbulent flow, so that water ripples and joint lines are prone to appear on the finished plastic parts, and the air in part of the film cavity is formed because it is too late to discharge. , so that the appearance of the finished product is flawed, which reduces the production quality, affects the production cycle, and is not convenient for production and use.

Utility model content

In order to solve the above problems, the utility model aims to provide a mold structure, in particular to a mold heating structure provided with a plurality of heating devices with heating pipes to heat the mold.

To achieve the above object, the technical solution adopted by the utility model is: a heating structure of a mold, including an upper mold and a lower mold that cooperate with each other, the upper mold and the lower mold are all provided with a heating device, and the heating device includes The heating plate and the heating mechanism arranged on the heating plate, the heating plate is provided with a containing groove, the heating mechanism is arranged in the containing groove, the heating mechanism includes a tubular heating element and the tubular The motor is electrically connected to the heating element.

Wherein, the heating device includes at least two heating plates arranged axially symmetrically to each other, each of the heating plates is provided with at least one accommodating groove distributed on its surface, and the accommodating groove has a cross section The square groove is composed of two parts: a square groove and an arc groove with an arc-shaped cross section, and the tubular heating element is fixedly clamped in the arc groove.

Wherein, the tubular heating element is a heating tube, the heating tube is electrically connected to the energized motor, and the heating tube is covered in the same track as the accommodating tank, and the heating tube is at least one A continuous pipe body or a plurality of intermittent pipe bodies.

Wherein, the tubular heating element is a liquid channel, and the liquid channel is provided with a heating drive.

Wherein, one side of the heating plate is connected to the mold body, the other side is provided with a heat preservation board, and a temperature sensor is provided between the heating plate and the heat preservation board.

The beneficial effect of the utility model is embodied as follows: the utility model aims to provide a heating structure of the mold, by setting independent heating devices on the upper mold and the lower mold respectively, so that the mold can ensure the overall temperature of the mold during the production process, avoiding The flow and filling of the molten plastic are affected by insufficient mold temperature, which improves the production quality and production efficiency of the overall product. It is convenient for production and use, and has a simple structure, low cost and strong practicability.
