Abstract
The utility model belongs to technical field of mold, provides the glue sealing structure putting magnesium alloy plate injection moulding in a kind of mould.Put the glue sealing structure of magnesium alloy plate injection moulding in this mould, comprise front core rod, rear core rod and magnesium alloy plate, described rear core rod and magnesium alloy plate junction are provided with boss; Described front core rod and magnesium alloy plate junction are provided with empty avoiding.According to the glue sealing structure putting magnesium alloy plate injection moulding in mould of the present utility model, avoid the bad problem of product that the foozle because of magnesium alloy plate is brought; Do not need die trial, only need to ensure that magnesium alloy plate size is in the margin of tolerance, improves production efficiency.
Description
Technical field
The utility model relates to injection mold structure, particularly relates to the glue sealing structure putting magnesium alloy plate injection moulding in a kind of mould.
Background technology
Mobile phone, day by day to high-end development, is had higher requirement to the structural strength of casing and stability, is required that product does in mould the design of putting magnesium alloy injection moulding, namely substitute plastic cement by part metals.Magnesium alloy is limited by processing and the forming errors of self mould, and the uncertainty of this error, make the product sealing of plastic mould extremely difficulty determine, all after mould die trial mostly, modify again according to die trial result, this brings very large puzzlement to product designer and mold designer, also greatly have impact on quality and the friendship phase of mould.Reality is, the manufacturing tolerance of magnesium alloy plate is ± 0.05mm, and the gap between plastic cement sealing face allows at most 0.015mm, exceedes just to there will be batch the many glue of envelope and cause product bad.Usually there will be two kinds of situations, one as shown in Figure 1, for the manufacture of product 10a, there is lower tolerance in magnesium alloy plate 30a, then front core rod 20a and rear core rod 40a fits, and occurs gap 50a between rear core rod 40a and magnesium alloy plate 30a, when gap 50a width is greater than 0.015mm, occur that product is bad; Another kind as shown in Figure 2, for the manufacture of product 10b, tolerance in magnesium alloy plate 30b appearance, then front core rod 10b, rear core rod 40b and and magnesium alloy plate 30b between fit, although magnesium alloy plate 30b is softer, because fitting area is too large and lack extension space, causes between front core rod 10b and rear core rod 40b and occur gap 50b, when gap 50b width is greater than 0.015mm, occur that product is bad.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides the glue sealing structure putting magnesium alloy plate injection moulding in a kind of mould.
For realizing above object, the technical solution adopted in the utility model is:
Put a glue sealing structure for magnesium alloy plate injection moulding in mould, comprise front core rod, rear core rod and magnesium alloy plate, described rear core rod and magnesium alloy plate junction are provided with boss; Described front core rod and magnesium alloy plate junction are provided with empty avoiding.
Described boss height 0.05mm, wide 3-5mm.
Described empty avoiding height 0.10mm.
The beneficial effects of the utility model: avoid the bad problem of product that the foozle because of magnesium alloy plate is brought; Do not need die trial, only need to ensure that magnesium alloy plate size is in the margin of tolerance, improves production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Fig. 1 is the partial enlarged drawing of the section of the glue sealing structure putting magnesium alloy plate injection moulding in prior art mould.
Fig. 2 is the partial enlarged drawing of the section of the glue sealing structure putting magnesium alloy plate injection moulding in prior art mould.
Fig. 3 is the profile putting the glue sealing structure of magnesium alloy plate injection moulding in a kind of mould according to the utility model preferred embodiment.
The partial enlarged drawing in Tu4Shi Tu3Zhong C district.
Detailed description of the invention
See Fig. 3-4, in a kind of mould, put the glue sealing structure of magnesium alloy plate injection moulding, for the manufacture of product 10, comprise front core rod 20, magnesium alloy plate 30 and rear core rod 40.It is highly the empty avoiding 21 of 0.1mm that front core rod 20 and magnesium alloy plate 30 junction are provided with.Rear core rod 40 is provided with boss 41 with magnesium alloy plate 30 junction, and boss 41 is highly 0.05mm, and width can be selected within the scope of 3-5mm as required.
Adopt said structure to carry out injection moulding constantly, there will be 2 kinds of situations, if magnesium alloy plate thickness is lower tolerance-0.05mm, then core rod and magnesium alloy plate are just fitted sealing; If interfere at boss place between magnesium alloy plate and rear core rod, during matched moulds, boss has first withstood, because the area of boss is less, additional magnesium alloy hardness ratio core rod steel are much little, the part that core rod boss and magnesium alloy are interfered, can extend to the room of both sides under the clamping pressure of injection machine, until the laminating of core rod sealing face, front and back is stressed, the mold clamping force of balance injection machine.Like this, the binding face sealing of magnesium alloy and front and back core rod can be ensured, front core rod and rear core rod binding face laminating sealing can be ensured again simultaneously.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, make concrete change or change and all belong to protection domain of the present utility model.
Claims (3)
