The present invention relates to a kind of injection molds.The injection mold includes upper mold and lower die, the upper mold is equipped with encapsulating mouth and the diversion trench communicated with encapsulating mouth, the lower die is set and the corresponding injection die cavities of component shape to be formed, the diversion trench is a plurality of, each diversion trench one end is connected with encapsulating mouth, the other end is uniformly distributed in the injection die cavities long side of lower die so that into the inflow drag intracavitary that is uniformly dispersed by diversion trench of injection molding material of encapsulating mouth;The diversion trench includes at least the first diversion trench and the second diversion trench of the injection die cavities both ends connection of the other end and lower die.Mold of the present invention sets plurality of guiding gutter, the melting charge that encapsulating mouth injects is imported to cavity to be molded by multiple diversion trenches, multiple diversion trenches can more preferably transfer injection molding machine pressure faster, enable the importing cavity that melting charge is uniform and stable, improve injection efficiency and ensure product quality simultaneously.

Description

A kind of injection mold
Technical field
The present invention relates to a kind of injection molds.
Background technology
Injection is a kind of method of industrial products production moulding, generally uses injection molding machine by thermoplastic or thermosetting property material Variously-shaped plastic products are made using mould for plastics.During injection, the mold of given shape is first made, on mold Encapsulating mouth is set, the material of melting is injected by encapsulating mouth by injection molding machine pressure, then the cavity of setting is flowed by flow-guiding channel Curing molding.Material flowing relies primarily on the mobility of the injection pressure and fluid of injection molding machine in itself and realizes during injection, works as injection Cavity it is larger or longer, injection molding machine pressure just uniformly can not be transferred quickly, not only reduce injection efficiency, and can influence product Compact density generates quality flaw.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of injection mold.
The technical problems to be solved by the invention are achieved by the following technical programs:A kind of injection mold, including upper Mould and lower die, the upper mold are equipped with encapsulating mouth and the diversion trench communicated with encapsulating mouth, and the lower die is set and component shape to be formed The corresponding injection die cavities of shape, it is characterised in that:The diversion trench is a plurality of, and each diversion trench one end is connected with encapsulating mouth, The other end is uniformly distributed in the injection die cavities long side of lower die so that the injection molding material into encapsulating mouth is uniformly dispersed by diversion trench Inflow drag intracavitary.
Preferably, the diversion trench include at least the injection die cavities both ends connection of the other end and lower die the first diversion trench and Second diversion trench.
There is choosing, the diversion trench is at least 3.
Preferably, the injection die cavities both ends of the lower die are equipped with extension slot.
Compared with prior art, the beneficial effects of the present invention are:The mold sets plurality of guiding gutter, passes through multiple diversion trenches The melting charge that encapsulating mouth injects is imported to cavity to be molded, multiple diversion trenches can more preferably transfer injection molding machine pressure faster, Enable the importing cavity that melting charge is uniform and stable, improve injection efficiency and ensure product quality simultaneously.

Fig. 2 is injection mold lower die structure schematic diagram of the present invention.
Specific embodiment
With reference to embodiment and attached drawing, the present invention is described in further detail, and embodiment and attached drawing are only used for explaining Illustrate rather than limit protection scope of the present invention.
As shown in attached drawing 1~2, the injection mold described in the present embodiment is made of upper mold 10 and lower die 20, upper mold 10 Upper setting encapsulating mouth 11, encapsulating mouth 11 penetrates through entire upper mold from upper mold upper surface open, and encapsulating mouth is in upper mold lower surface exit Connect plurality of guiding gutter 12, diversion trench 12 is extending to lower die with component shape to be molded from encapsulating mouth on the inner surface of upper mold At the corresponding cavity of size.
In the present embodiment, lower die treats injection die cavities as a longer rectangle structure, is set in the inner surface of upper mold Three flow-guiding channels are respectively:One end is connected with encapsulating mouth 11, the first end of injection die cavities connection of the other end and lower die First diversion trench 121, one end are connected with encapsulating mouth 11, the second water conservancy diversion of the second end of injection die cavities connection of the other end and lower die Slot 122 and one end are connected with encapsulating mouth 11, the 3rd diversion trench 123 of connection in the middle part of the injection die cavities of the other end and lower die.When 4th diversion trench can also be so set, and the other end of the 3rd diversion trench and the 4th diversion trench outlet at this time can be located at rectangle respectively Three branch positions of the long side of injection die cavities.In use, upper and lower mould snaps together, moulding is treated in centre clamping, after having good positioning, Injection molding material is injected from upper mold, injection molding material flows into lower die cavity 21 through encapsulating mouth diversion trench, is cooled and shaped in lower die cavity 21, with Treat that moulding is combined together to form product.Structure of the present invention can be flowed into uniformly in the long side direction of lower die injection die cavities Injection molding material, injection molding material pressure is uniform in each diversion trench, and flow velocity is basically identical, and the sizing material of each diversion trench flows into injection molding Melting is met one another after intracavitary, since injection molding material is pressurized in each diversion trench and flow velocity is essentially identical, injection molding material, which converges, after the meeting can It combines well, internal each stress is essentially identical after formed product, is tightly combined, ensure that product quality.
During specific design, the quantity of diversion trench is determined according to the shapes and sizes of component cavity to be molded, generally in cavity Length direction is uniformly distributed diversion trench.When cavity length is longer, diversion trench set it is more, otherwise diversion trench then set compared with It is few.In addition, when cavity length is longer, after diversion trench distribution, there are many water conservancy diversion flute length at the opposite middle part of diversion trench meeting of both sides, this When the diversion trench of both sides can be set it is corresponding wider.In addition extension slot 22, extension slot are equipped at the injection die cavities both ends of lower die 22 dashpot as injection molding material enables injection to have flow fused in redundant space, the injection molding material at cavity wall is avoided to dash forward Accumulation of being so obstructed causes product density and the different product quality problems generated of internal stress.Shaping after shaping in extension slot 22 Material can be removed by post-processing.
Although description of this invention combination embodiments above carries out, those skilled in the art Member can carry out many replacements, modifications and variations according to above-mentioned content, be obvious.Therefore, it is all it is such substitute, It improves and variation is included in the spirit and scope of appended claims.
