Description
Technical field
The utility model is related to mould production technical field, more particularly to a kind of injection mold.
Background technology
As depicted in figs. 1 and 2, at present in injecting products processing, the material for being molded adds glass increasingly
It is many, and add the material after glass harder, relatively more crisp.In material hardness than in the case of larger, if injection mold is provided with
During cow glue powder 1, because of back-off amount nearly 4.28mm of the existing cow glue powder 1 on die 5, grown equivalent to whole cow glue powder 1
2/3rds of degree, cause in ejection, and whole cow glue powders 1 need bending by force.Cow glue powder 1 is caused often to break in mould
In benevolence 5, mould need to descend mould to remove cast gate defective material, and injection machine machinery production in ability, production efficiency is very low.It is above-mentioned in order to solve
Problem, when being molded using other cast gates, also needs manually to go to prune.And the yield manually pruned is relatively low, also add manpower and materials,
Production cost is higher.
Utility model content
For above-mentioned deficiency, technical problem to be solved in the utility model is：A kind of injection mold is provided, the mould
Back-off amount is small at the cast gate of cow glue powder, so as to reduce the resistance of mould demoulding in ejection, realizes cow glue powder and produces
Being automatically separated for product, without artificial pruning, improves production efficiency.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of injection mold includes die, and the die is divided into front cavity and rear cavity, the front cavity and the rear mold
Cow glue powder is provided between benevolence, also including mold insert, the mold insert be arranged on the front cavity on, and the mold insert one end and institute
State the distance between the cow glue powder connection in front cavity, the mold insert and cast gate of the cow glue powder and be less than or equal to institute
State 1/3rd of the length of cow glue powder.
Preferred embodiment is that the cow glue powder is provided with reinforcement structure, and the reinforcement structure is near the cow glue powder
Cast gate side is set.
Preferred embodiment is, the mold insert also includes the straight section being connected with the front cavity, the length of the straight section with it is described
The width of front cavity is identical.
Preferred embodiment is, also including the runner being connected with the cow glue powder, the mold insert simultaneously with the cow glue powder
Connected with the part runner.
Preferred embodiment is, also including two thimbles, wherein a thimble is located at the lower section of the cow glue powder, it is another
Thimble described in root is located at the lower section of product.
After adopting the above technical scheme, the beneficial effects of the utility model are：Due to injection mold bag of the present utility model
Die is included, die is divided into front cavity and rear cavity, cow glue powder is provided between front cavity and rear cavity.The utility model also includes
Mold insert, the mold insert is arranged in front cavity, and one end of mold insert is connected with the cow glue powder in front cavity, because mold insert is poured with ox horn
The distance between cast gate of mouth makes the back-off amount of cow glue powder diminish less than or equal to 1/3rd of the length of cow glue powder, from
And resistance of the mould when the cast gate demoulding is ejected is reduced, and being automatically separated for cast gate and product is realized, without artificial pruning, enter
And improve production efficiency.
Because cow glue powder is provided with reinforcement structure, reinforcement structure is set near the cast gate side of cow glue powder；Further keep away
The situation generation in the fracture of demoulding cow glue powder is exempted from.
Also include the straight section being connected with front cavity due to mold insert, the length of the straight section is identical with the width of front cavity；The knot
Structure makes mold insert have enough intensity, goes to be connected with cow glue powder.
Due to also including the runner being connected with cow glue powder, mold insert is connected with cow glue powder and portion of runner simultaneously；The knot
Structure further ensures the bonding strength of mold insert and cow glue powder.
In sum, injection mold of the present utility model compared with prior art, is solved in the prior art because ox horn is poured
2/3rds of the cast gate back-off amount nearly cow glue powder entire length of mouth, make it be easily broken off in the demoulding, cause production to be imitated
The low technical problem of rate；And injection mold of the present utility model, the mold insert being connected with cow glue powder is which increased, reduce ox horn
The back-off amount of cast gate, enables cow glue powder and product to be automatically separated, and cow glue powder is not susceptible to fracture, it is ensured that raw
Produce efficiency.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, a kind of injection mold includes die 5, and die 5 is divided into front cavity 50
With rear cavity 51, cow glue powder 1 is provided between front cavity 50 and rear cavity 51.Also include mold insert 3, mold insert 3 is arranged on front cavity
On 50, and one end of mold insert 3 is connected with the cow glue powder 1 in front cavity 50, between the cast gate 10 of mold insert 3 and cow glue powder 1
/ 3rd of distance less than or equal to the length of cow glue powder 1.
As shown in Fig. 4, Fig. 6 and Fig. 8, the cow glue powder 1 of the present embodiment is provided with reinforcement structure 4, and reinforcement structure 4 is close to and pours
10 sides of mouth are set, there is provided the cow glue powder 1 of reinforcement structure 4 is in the demoulding, even if material hardness is big, be not easy to fracture.
As shown in figure 3, the mold insert 3 of the present embodiment also includes the straight section being connected with front cavity 50, the length and front mould of straight section
The width of benevolence 50 is identical, and this straight section makes mold insert 3 have enough intensity, goes to be connected with cow glue powder 1.
Also include the runner 6 being connected with cow glue powder 1, mold insert 3 is connected with cow glue powder 1 and portion of runner 6 simultaneously.Also
It is that mold insert 3 is crossed on runner 6 and cow glue powder 1, makes structural strength sufficiently large.
Injection mold of the present utility model also includes two thimbles 7, wherein a thimble 7 is located at the lower section of cow glue powder 1,
Another thimble 7 is located at the lower section of product 2.
In production, under matched moulds state, front cavity 50 and rear cavity 51 are combined injection mold of the present utility model.
From nozzle material out after runner 6 enters cow glue powder 1, some material is molded in front cavity 50；Namely
Mold insert 3 makes the back-off amount of cow glue powder 1 be reduced to three point of the entire length of cow glue powder 1.After die sinking, mold insert 3 is by front cavity
50, with leaving, deformation space are conceded to cow glue powder 1.In the presence of thimble 7, cow glue powder 1 is ejected, because it is ejected
When the resistance that is born diminish, its only head is there occurs deformation, so that cow glue powder 1 will not be because of when pushing up on thimble 7
Power, and by the fracture of bending by force, that is, without cow glue powder 1 is removed, waste material is removed, can continuously produce, so as to improve
Production efficiency.Because cow glue powder 1 is easily raised, it is realized with product 2 and be automatically separated, further increase life
Produce efficiency.
The above preferred embodiment of the present utility model, is not used to limit the utility model, all in this practicality
Any modification for being made within new spirit and principle, etc. the improvement of same injection mold structure etc., should be included in this
Within the protection domain of utility model.
