Problems solved by technology

The positioning is relatively protected and not easy to damage, but due to the step transfer in the heat transfer process, the heat loss is large and the power consumption is large. At the same time, the change of air temperature with climate change also makes the thermal stability of the mold relatively poor.

Embodiment Construction

[0013] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the mold for direct heating provided by the present invention includes an operating table 1, a mold body 2, and a base 3 stacked from top to bottom; the mold body 2 includes an upper mold 21 and a lower mold 22 arranged symmetrically up and down; The mold 21 is arranged below the console 1, and the lower mold 22 is arranged above the base 3; the upper end of the upper mold 21 and the lower end of the lower mold 22 are respectively provided with several heating pipes 4.

[0015] The mold body 2 is made of heat-conducting metal material, such as steel. It is thus possible to conduct the heat of its internal heating tube 4 to the thermosetting plastic material in the mold body 2 .

[0016] The heating tubes 4 are horizontally and parallelly spaced in the upper part of the upper mold 21 or inside the lower par...

Abstract

The invention discloses a mould for direct heating. The mould comprises an operation table, a mould body and a base which are overlaid from top to bottom, wherein the mould body comprises an upper mould and a lower mould which are symmetrically arranged, the upper mould is arranged under the operation table, and the lower mould is arranged above the base; and a plurality of heating pipes are respectively arranged in the upper end portion of the upper mould and the lower end portion of the lower mould, and the heating pipes which are electric heating pipes are sequentially and horizontally arranged in parallel in the upper end portion of the upper mould or the lower end portion of the lower mould at intervals. A layer of thermal insulation pad is further arranged between the upper mould and the operation table and between the lower mould and the base respectively. The upper mould is connected with the lower mould in unfixed mode. The length of the edges of the operation table and the base is larger than or equal to the length of the corresponding edge of the mould body, and the mould body is a heat-conducting metal mould. The mould for direct heating enables heat transferring to be more direct, is small in heat energy loss and power consumption, obviously improves thermal instability and is important for technological stability in mould plastic product processing.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for directly heating thermosetting molding compound. Background technique [0002] In the heat transfer form of the material during the processing of the thermosetting molding compound, the traditional way is to transfer the heat to the mold through the electric heating tube set on the workbench, and then transfer the heat to the molding compound through the mold, so that it will produce a chemical reaction until it is completely cured and released. After the mold, it becomes a primary product, and finally through subsequent processing, it becomes a product after passing the inspection. This form of directly using the workbench to transfer heat is characterized in that the electric heating tube does not need to move after it is fixed in the special hole of the workbench. The positioning is relatively protected and not easy to damage, but due to the step transfer during the heat transfer process,...
