Description
Technical field
The utility model belongs to automobile die technology field, more particularly to a kind of mold of automotive trim Injection Molding Products
Thimble structure.
Background technology
It requires to gradually increase with regard to current automobile industry standard, approves to be also increasingly for the surface of interior trim Injection Molding Products
Difficulty epitome, bulge cannot occur for product surface, and blushing provides the improvement introduction of die ejector pin design aspect, for
It is in the majority that pervious thimble end face is generally plane, then product surface problem can be caused to add.
Therefore, above-mentioned technical problem how to be overcome to become those skilled in the art's technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is just to provide a kind of ejector pin structure of die of automotive trim Injection Molding Products, can solve completely
In place of certainly above-mentioned the deficiencies in the prior art.
The purpose of this utility model is realized by following technical proposals：
A kind of ejector pin structure of die of automotive trim Injection Molding Products, including thimble, oblique top neutron, ejector retainner plate and thimble pressure
Plate, the thimble pressing plate are mounted on die bottom plate, and thimble pressing plate connects ejector retainner plate, and oblique top neutron is installed on the ejector retainner plate,
Thimble is set on oblique top neutron, and the thimble end face is provided with sawtooth or Wave-shaped structural, for demoulding.
Preferably, the ejector retainner plate is mounted on by thimble plate screw on thimble pressing plate.
Preferably, the thimble is using thimble made of high-speed steel.
Preferably, the thimble surface is provided with one layer of wearing layer.
Preferably, the wearing layer is using wearing layer made of carbofrax material.
Compared with prior art, the beneficial effects of the utility model are：Simple in structure, reasonable design, thimble end face is set
It is set to sawtooth or Wave-shaped structural, can effectively avoid and occur phenomena such as epitome, bulge, whiten on automotive trim Injection Molding Products,
Improve product quality.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is thimble working state figure.
Reference numeral：Thimble（1）, oblique top neutron（2）, ejector retainner plate（3）, thimble pressing plate（4）, sawtooth or Wave-shaped structural
（5）, thimble plate screw（41）, die bottom plate（6）, mould bases（7）, mode（8）.
Specific implementation mode
The utility model is further described with reference to specific embodiments and the drawings.
As shown in Figure 1 to Figure 2, a kind of ejector pin structure of die of automotive trim Injection Molding Products, including in thimble 1, oblique top
Son 2, ejector retainner plate 3 and thimble pressing plate 4, the thimble pressing plate 4 connect ejector retainner plate 3, install oblique top neutron 2 on the ejector retainner plate 3, tiltedly
It pushes up and thimble 1 is set on neutron 2,1 end face of the thimble is provided with sawtooth or Wave-shaped structural 5, for demoulding.
The ejector retainner plate 3 is mounted on by thimble plate screw 41 on thimble pressing plate 4.
The thimble 1 is using thimble made of high-speed steel.
1 surface of the thimble is provided with one layer of wearing layer.
The wearing layer is using wearing layer made of carbofrax material.
The thimble pressing plate 4 of this structure is mounted on the die bottom plate 6 in mold, and centre hole is provided on the mould bases 7 of mold,
Thimble 1 is through in centre hole, and mode 8 is fixed with by mould bases positioning pin on mould bases 7.During mold releasability, front and back mould
It opens, since plastics expand with heat and contract with cold, it is not to be easy to demould that product and die cavity, which have certain package power, product, then by 1 liter of thimble
Go out, withstands in the plane in the faces B of product.Traditional thimble face area is smaller, so the power acted on product is larger, product meeting
It is recessed, leads to wall unevenness, finally results in thimble during product B face stress so that the faces A will appear bulge, whiten
Phenomena such as, automobile industry absolutely not allows when doing appearance approval, so the thimble structure is added in 1 end face of thimble
After sawtooth or Wave-shaped structural 5, wall unevenness caused by the opposite recess for reducing large area, to ensure that the faces A are intact.
The utility model is simple in structure, reasonable design, and 1 end face of thimble is provided with sawtooth or Wave-shaped structural 5, can effectively keep away
Exempt from occur phenomena such as epitome, bulge, whiten on automotive trim Injection Molding Products, improves product quality.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
