Abstract
A traceless injection molding die comprises an outer die, an inner die and a circuit system controlling the outer die and the inner die. The traceless injection molding die is characterized in that the inner die is provided with a heating device, the heating device comprises a heating part, a temperature sensing line, a terminal box and a temperature control box, the inner die is provided with a mounting groove matching with the temperature sensing line, the heating part is located below the mounting groove, one side of the inner die is provided with a mounting hole matching with the heating part, the mounting groove is provided with a hole located below the temperature sensing line, the inner die is provided with a wire slot communicated with the mounting groove, the heating part and a power cord of the temperature sensing line are connected with the terminal box through the wire slot, and the heating part is a heating bar. The traceless injection molding die is simple in structure, high in production efficiency and low in cost, and can reduce weld marks through increasing local temperature of the die.
Description
Technical field
The utility model relates to the technical field of injection mold, especially a kind of no-trace injection-die.
Background technology
At present, existing mold after two bursts of materials flows are met, tend to form defectives such as weld mark, current mark, ripple at plastic product surface, and this advances glue for multiple spot or has to bump the plastic product of wearing structure except that high optical mode tool, especially inevitable.Above-mentioned defective not only influences the outward appearance of plastic product, and has reduced the intensity of plastic product, and the client is difficult to accept for hindering the attractive in appearance and unsettled plastic product of quality.Though high optical mode tool can address the above problem, the cost of manufacture of high optical mode tool and machining accuracy height require also quite strictness for operators'skills, are difficult to penetration and promotion.People set up temperature-sensitive and heater at mould for this reason, greatly reduce the probability that weld mark occurs, yet, when mould has two or more hot mouths, generally to add a terminal box, increased the structural complexity and the manufacturing cost of a whole set of mould.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, can reduce weld mark, production efficiency height and the low no-trace injection-die of cost by the local temperature that improves mould.
Goal of the invention of the present utility model is achieved in that a kind of no-trace injection-die, the Circuits System that comprises the running of external mold, internal mold and control external mold and internal mold, it is characterized in that: internal mold is provided with electro-heat equipment, described electro-heat equipment comprises and the interconnective heat generating member of Circuits System, temp.-sensing wire, terminal box and temperature control box, have the mounting groove adaptive with temp.-sensing wire on the described internal mold, heat generating member is positioned at the mounting groove below.
Described internal mold one side has the installing hole with the adaptive installation of heat generating member.
Have emptiness avoiding hole on the described mounting groove, emptiness avoiding hole is positioned at the below of temp.-sensing wire.
Have the wire casing that is communicated with mounting groove on the described internal mold, the power line of heat generating member and temp.-sensing wire is connected with terminal box by wire casing.
Described heat generating member is a heating bar.
The utility model improves existing injection mold, on internal mold, set up the electro-heat equipment of forming by parts such as heat generating member, temp.-sensing wire, terminal box and temperature control boxs, by improving the local temperature of mould, reduce the folder waterline, improve stability in the mold work process, enhance productivity greatly.Have adaptive with temp.-sensing wire, heat generating member and power line respectively mounting groove, installing hole and wire casing on the internal mold, the power line of heat generating member and temp.-sensing wire is guided to terminal box, convenient installation and safe in utilization.
Description of drawings
Accompanying drawing 1 is the structure principle chart of the utility model most preferred embodiment;
Accompanying drawing 2 is the structural representation of the utility model most preferred embodiment;
Accompanying drawing 3 is the structural representation of internal mold.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in 1 to 3, no-trace injection-die of the present utility model comprises the Circuits System that external mold, internal mold 1 and control external mold and internal mold 1 operate with reference to the accompanying drawings.Internal mold 1 is provided with electro-heat equipment, this electro-heat equipment comprises and the interconnective heat generating member of Circuits System, temp.-sensing wire 2, terminal box and temperature control box that wherein heat generating member is a heating bar, the convenient installation, temperature control box can directly adopt the TOP-TIP of mould, reasonably reduces the use of parts.Have the mounting groove 3 adaptive with temp.-sensing wire 2 on the internal mold 1, a side of mounting groove 3 belows, internal mold 1 has the installing hole 4 adaptive with heat generating member.Result according to mold flow analysis is installed on the position that water is pressed from both sides in most possible appearance with heat generating member, and heat generating member is installed on internal mold 1 the inside, reduces the probability that weld mark occurs greatly, and temp.-sensing wire 2 is installed near the heat generating member, and reasonable circuit layout is convenient.Have emptiness avoiding hole 5 on the mounting groove 3, this emptiness avoiding hole 5 is positioned at the below of temp.-sensing wire 2, and it is impaired to avoid temp.-sensing wire 2 or other power line to be extruded when external mold and internal mold 1 matched moulds, uses safer.Have the wire casing 6 that is communicated with mounting groove 3 on the internal mold 1, the power line of heat generating member and temp.-sensing wire 2 is connected with terminal box by wire casing 6, when mould has two or more hot mouths, still can only use single terminal box, the reduction manufacturing cost of a whole set of greatly mould.
