Abstract
The utility model relates to a kind of injection molds, for forming the product with pre- fault trough, including upper mold and lower mold, the upper forming surface and lower forming surface that upper mold and lower mold are respectively provided with opposite to each other to form forming cavity, it is characterized in that, a convex block is respectively arranged in the certain distance d that extends outwardly at the gate location that upper forming surface and lower forming surface correspond to product, and it is highly 0.10 millimeter that the width of the convex block, which is 0.05 millimeter,.The utility model on the one hand can be improved product quality yield, on the other hand can steady production, improve production efficiency.
Description
Technical field
The utility model relates to a kind of injection molds, more particularly to a kind of for forming the note of the product with pre- fault trough
Mould.
Background technique
During the prior art is used, the junction (cast gate) of injecting products and runner waste material is directly connected to, mask work
Using cold cut, earnestly, the modes such as ultrasonic wave carry out operation.By taking ultrasonic wave as an example, product product and injection molding under ultrasonic wave effect
Waste material separation, fracture position between the two be it is unfixed, which results in product gate location will appear waste material residual, produce
The exterior qualities problems such as product damage.
Summary of the invention
The utility model is intended to provide a kind of injection mold, to solve the above technical problems.For this purpose, the utility model uses
Specific technical solution it is as follows:
A kind of injection mold, for forming the product with pre- fault trough, including upper mold and lower mold, upper mold and lower die
Tool is respectively provided with opposite to each other upper forming surface and lower forming surface to form forming cavity, which is characterized in that in upper forming surface under
A convex block is respectively arranged corresponding to the certain distance d that extends outwardly at the gate location of product in forming surface, and the width of the convex block is
0.05 millimeter, be highly 0.10 millimeter.Therefore, upper and lower surface of the product after molding at cast gate respectively has width 0.05mm, height
Spend the groove of 0.10mm.Product in this way is when ultrasonic wave is super disconnected, the fracture that product can be smooth along this groove, to reach disconnected
The smooth stable effect of trace, meets the requirement of quality and production.
Preferably, the distance d is 0.2 to 0.5 millimeter.
It is highly preferred that the distance d is 0.3 millimeter.
Preferably, the convex block is arranged by the way of welding.
The utility model by adopting the above technical scheme, has the beneficial effect that on the one hand the utility model can be improved
Product quality yield, on the other hand can steady production, improve production efficiency.
Detailed description of the invention
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.

Partial enlargement is carried out in position；
Fig. 2 is the schematic diagram of the upper mold of the injection mold of the utility model, wherein in order to show convex block, to convex block institute
Partial enlargement is carried out in position；
Fig. 3 is the schematic diagram using the molding product of the injection mold of the utility model, wherein is prejudged to show
Slot carries out partial enlargement to pre- fault trough position.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figures 1 to 3, a kind of injection mold is used to form the product 3 with pre- fault trough 31, including upper mold 1 is under
Mold 2.The upper forming surface and lower forming surface that upper mold 1 and lower mold 2 are respectively provided with opposite to each other to form forming cavity.It is upper at
Type face and lower forming surface correspond at the gate location of product the certain distance d that extends outwardly and a convex block 11 and 21 are respectively arranged, should
The width of convex block 11 and 21 is 0.05 millimeter, is highly 0.10 millimeter.Therefore, product 3 after molding at cast gate up and down two
Respectively there are the groove (pre- fault trough) 31 of width 0.05mm, height 0.10mm in face.Product in this way using ultrasonic wave when being fractureed, product meeting
It is entirely broken along this groove 31, to achieve the effect that mark of break is smooth stable, meets the requirement of quality and production.
Preferably, the distance d is 0.2 to 0.5 millimeter.It is highly preferred that the distance d is 0.3 millimeter.
The convex block 11 and 21 can be arranged by the way of welding, be transformed with facilitating to existing mold, save system
This is caused, the mold production time is reduced, improves production efficiency.Certainly, in the case where mold is completely newly processed, convex block 11 and 21 can
It is made with being integrally machined with upper/lower die, without using welding.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the protection scope of the utility model.
