Abstract

The utility model discloses a mould with an automatic water gap removing function. The mould with the automatic water gap removing function comprises a front mould cavity, a pushing spring, a pressure lever, a rear mould cavity, a cutter tool and a spring, wherein the front mould cavity is matched with the rear mould cavity; a flow passage is arranged on the mating surface of the front mould cavity and the rear mould cavity; the rear mould cavity is provided with a cavity communicated with the flow passage; the pushing spring and the pressure lever are mounted in the front mould cavity; the pushing spring is matched with the pressure lever; the pressure lever is positioned above the mould cavity; the cutter tool and the spring are mounted on the rear mould cavity; and the cutter tool is positioned at the joint of the cavity and the flow passage. The mould with the automatic water gap removing function is simple in structure and reasonable in design, and the water gap can be removed automatically after opening an injection mould by matching the pressure lever and the cutter tool with the spring respectively.

Description

Mould with automatic mouth of a river excision function

Technical field

The utility model relates to a kind of injection mold, specifically a kind of mould with automatic mouth of a river excision function.

Background technology

Along with the extensive use of working of plastics in each electron-like, electrical equipment and engineering goods.Present plastics adopt injection molded mostly, in injection moulding process, glue-feeder on the product is the mouth of a river, in order to guarantee the efficient of injection moulding, saves production cost, generally can design a plurality of die cavities at injection mold, adopt a plurality of glue-feeders, this just makes the working of plastics of injecting products after injection moulding is finished that the mouth of a river is arranged, after formed product, for product can normally be used, the mouth of a river on the product need be excised.

The design of automatic mouth of a river excision is not arranged in traditional injection mold, so the operation that the product that goes out from injection mould processing also needs to carry out mouth of a river excision, present mouth of a river cutting method is to adopt manual cutting.But it is lower that manual cutting not only can expend the efficient of a large amount of manpowers and mouth of a river excision, can't catch up with the requirement of enterprise's high-speed production, also because must use cutter when cutting, this loses because of operate miss with regard to the personnel that cause easily, has certain potential safety hazard simultaneously.

The utility model content

The purpose of this utility model is to overcome the deficiency that the traditional injection moulding mould can not excise the mouth of a river automatically, and a kind of mould with automatic mouth of a river excision function is provided.

For achieving the above object, the technical scheme that adopts of the utility model is:

A kind of mould with automatic mouth of a river excision function includes preceding die, following pressing spring, depression bar, back die, cutting tool and spring,

Preceding die cooperates with the back die;

Preceding die is provided with runner with the mating surface of back die;

Design has the die cavity that is connected with described runner on the back die;

Following pressing spring, depression bar are installed in the preceding die;

Following pressing spring matches with depression bar;

Described depression bar is positioned at the die cavity top;

Cutting tool and spring are installed on the die of back;

Described cutting tool position is in the junction of die cavity and runner.

Operation principle of the present utility model is: behind the mould matched moulds, after injection moulding was finished, depression bar was under the effect of following pressing spring, and depression bar compresses the product that is positioned at die cavity; After the mould die sinking, depression bar continues to compress product because of the following effect of pressing spring, and at this moment, the cutting tool of back die cuts because of the effect of the spring contact-making surface to die cavity and runner, finishes the excision work at the mouth of a river.

The utility model is simple in structure, and is reasonable in design, by depression bar and cutting tool respectively with the cooperating of spring, finish after the injection mold die sinking automatically the excision to the mouth of a river.

The specific embodiment

To understanding of the present utility model, existing by reference to the accompanying

drawings

1,2 for an embodiment for convenient, the utility model is made further instruction.

Embodiment:

With the mould of automatic mouth of a river excision function, die 1, following pressing spring 2, depression bar 8, back die 4, cutting tool 5 and spring 6 before including,

Preceding die 1 cooperates with back die 4;

Preceding die 1 is provided with runner 3 with the mating surface of back die 4;

Design has the die cavity 7 that is connected with described runner 3 on the back die 4;

Following pressing spring 2, depression bar 8 are installed in the preceding die 1;

Following pressing spring 2 matches with depression bar 8;

Described depression bar 8 is positioned at die cavity 7 tops;

Cutting tool 5 and spring 6 are installed on the die 4 of back;

Described cutting tool 5 positions are in the junction of die cavity 7 with runner 3.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but all technical solutions of the utility model contents that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.

Claims

1. the mould with automatic mouth of a river excision function includes preceding die, following pressing spring, depression bar, back die, cutting tool and spring, it is characterized in that: preceding die cooperates with the back die; Preceding die is provided with runner with the mating surface of back die; Design has the die cavity that is connected with described runner on the back die; Following pressing spring, depression bar are installed in the preceding die; Following pressing spring matches with depression bar; Described depression bar is positioned at the die cavity top; Cutting tool and spring are installed on the die of back; Described cutting tool position is in the junction of die cavity and runner.
