Description

A kind of constant temperature injection mold

Technical field

The utility model belongs to injection mold field, specifically refers to a kind of constant temperature injection mold.

Background technology

Many injecting products in shaping, are needed mold temperature higher, and will be kept to reach outward appearance condition now Stable uniform with heating, present mould is substantially to be realized by connecing the water or oil of high-temperature in mould, but this method is asked Topic is not very stable, generates heat uneven yet, and the temperature for rising is limited, does not reach the forming requirements of some products, is so accomplished by Do and a kind of can rise high temperature and the uniform and stable structure of generating heat.

Utility model content

The utility model is in order to overcome the deficiency of prior art, it is proposed that a kind of constant temperature injection mold.

The utility model is to solve above-mentioned technical problem by following technical proposals.

A kind of constant temperature injection mold, including upper mould, upper cores, lower mould and lower die, upper cores are fixed on mould bottom, under Die is fixed at the top of lower mould, and upper die and lower die matched moulds coordinates, and is provided with and is attached to upper cores between upper cores and upper mould bottom The heating mechanism at top, the heating mechanism include being successively set on from bottom to up heating wire group at the top of upper cores, heating board And thermal insulation board, the heating board lower surface and upper surface are respectively arranged with the installing space for accommodating heating wire group and thermal insulation board.

One kind as the utility model constant temperature injection mold is improved, and the thermal insulation board is asbestos slate material members.

One kind as the utility model constant temperature injection mold is improved, and heating wire group includes two groups of heating wires, and respectively the One heating wire and the second heating wire, first heating wire and the second heating wire is arranged in a ring and both are generally aligned in the same plane Interior, the first heating wire is set in qually spaced in inside the second heating wire.

The beneficial effects of the utility model are, in this way after, in injection debugging, the temperature of mould can for mould To reach forming requirements, and it is uniform to generate heat, and mold temperature can be made to reach the temperature that common water temperature is not reached, and can keep temperature Stablizing for degree, while being provided with thermal insulation board, it is to avoid heat is passed up to mould, reduces the loss of heat.
