Abstract
The utility model discloses a kind of core structure of injection mold, its stainless steel block including the bottom forming die cavity with die cavity, the top upwards extended by bottom and be arranged at top; A first row air drain is offered in the middle part of described upper side, and described top offers near bottom place the deep gouge that arranges stainless steel block, described deep gouge is connected with first row air drain, and described piece of stainless steel body side surface offers the second row air drain of a connection first row air drain; By said structure, the core structure of the utility model injection mold can improve the mold use life-span, and can produce excellent product.
Description
Technical field
The utility model relates to a kind of die apparatus, refers in particular to a kind of core structure of injection mold.
Background technology
Because plastic product forming is fast, so comparatively fast developed.The forming method of plastic products has a lot, as injection moulding, extrusion molding, blowing etc.Wherein, the profiled part of injection mold comprises die cavity and core, and die cavity and core form the die cavity of goods; And the material having become melt enters sprue, through runner, cast gate is injected in die cavity, and material opens mould after cooling stage, takes out the product of injection mo(u)lding.
General when carrying out injection moulding, if the air that mould inside is remaining, injecting products inside will be involved in, so by defects such as gassings, therefore, need to arrange exhaust outlet in mould, described exhaust outlet is communicated with the die cavity of mould, and when injecting material, the air in die cavity will be discharged die cavity from exhaust outlet, avoid air to be involved in injecting products inside, air can be obtained and all discharge and do not have leachy excellent products formed.
But, existing mould is all that iron material is made, the pernicious gas erosion that the exhaust outlet of iron material produces through high-temperature material for a long time there will be corrosion phenomenon, the product of injection mo(u)lding is caused to have burr in exhaust ports, not only increase the consume of material, and need the later stage to clear up burr, increase work two and affect the acceptance rate of product; Long-term injection moulding rear exhaust port possibly cannot use, and causes whole mould all cannot use, affects the mold use life-span.
In view of this, the design people for above-mentioned mould structure design not being attained perfect caused many disappearances and inconvenience, and deeply conceives, and active research improvement has a fling at and development and Design goes out this case.
Utility model content
The purpose of this utility model is the core structure providing a kind of injection mold, and it can improve the mold use life-span, and can produce excellent product.
In order to reach above-mentioned purpose, solution of the present utility model is:
A core structure for injection mold, its stainless steel block including the bottom forming die cavity with die cavity, the top upwards extended by bottom and be arranged at top; A first row air drain is offered in the middle part of described upper side, and described top offers near bottom place the deep gouge that arranges stainless steel block, described deep gouge is connected with first row air drain, and described piece of stainless steel body side surface offers the second row air drain of a connection first row air drain.
The degree of depth of described first row air drain is greater than the degree of depth of second row air drain.
The width of described first row air drain is greater than the width of second row air drain.
Described piece of stainless steel body side surface and upper side are at grade.
Described core inside is also provided with cooling water channel.
Described cooling water channel include multiple water inlet, being arranged at upper end be arranged at bottom near the delivery port of bottom sidewall and multiple core that is arranged at inner and connect the pipeline of water inlet and delivery port.
Adopt after said structure, the core structure of the utility model injection mold arranges a stainless steel block on core top, and offers first row air drain and second row air drain on core top and stainless steel block; Not only the air in die cavity can be discharged, avoid air to be involved in product, produce bad finished product; And the relative iron corrosion resistance of stainless steel is stronger, the second row air drain on described stainless steel block is more durable, improves the whole mold use life-span, and can reduce the consume of material, and does not need the later stage to clear up burr, increases work efficiency; When the pernicious gas corrosion that stainless steel block is produced by high-temperature material, only need change piece of stainless steel just passable, not want to change whole core, save maintenance cost.

Detailed description of the invention
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
Refer to Fig. 1 to Fig. 4, the utility model discloses a kind of core structure of injection mold, its stainless steel block 3 including the bottom 1 forming die cavity with die cavity, the top 2 upwards extended by bottom 1 and be arranged at top 2; Described top 2 offers a first row air drain 21 in the middle part of side, and described top 2 offers near bottom 1 place the deep gouge 22 that arranges stainless steel block 3, described deep gouge 22 is connected with first row air drain 21, and described stainless steel block 3 side opening is provided with the second row air drain 31 of a connection first row air drain 21.
The core structure of the utility model injection mold arranges a stainless steel block 3 on core top, and offers first row air drain 21 and second row air drain 31 on core top 2 and stainless steel block 3; Not only the air in die cavity can be discharged, avoid air to be involved in product, produce bad finished product; And the relative iron corrosion resistance of stainless steel is stronger, the second row air drain 31 on described stainless steel block 3 is more durable, improves the whole mold use life-span, and can reduce the consume of material, and does not need the later stage to clear up burr, increases work efficiency; When the pernicious gas corrosion that stainless steel block 3 is produced by high-temperature material, only need change piece of stainless steel 3 just passable, not want to change whole core, save maintenance cost.
The degree of depth of the described first row air drain 21 of the core structure of the utility model injection mold is greater than the degree of depth of second row air drain 31, and the degree of depth of described second row air drain 31 is 1/20th of degree of depth of first row air drain 21; And the width of described first row air drain 21 is greater than the width of second row air drain 31; Described second row air drain 31 is very little and very shallow, avoids material to be injected on second row air drain 31 as far as possible, can the generation of maximum limits product burr.
Described stainless steel block 3 side of the core structure of the utility model injection mold and side, top 2 are at grade; Make stainless steel block 3 side not protrude from side, top 2, ensure the compactness of each parts of mould.
The described core inside of the core structure of the utility model injection mold is also provided with cooling water channel 4; Described cooling water channel 4 include multiple water inlet 41, being arranged at top, top 2 be arranged at bottom 1 near the delivery port 42 of bottom sidewall and multiple core that is arranged at inner and connect the pipeline 43 of water inlet 41 and delivery port 42; In described cooling water channel 4, inject the cooling water of circulation, core can be made to cool fast, uniformly, and ensure the quality of product, improve the qualification rate of product.
Above-described embodiment and accompanying drawing non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
