The electric tool motor base mold comprises fixed plates, molds, a guide pillar, ejector retainer plates, and a sprue brushing, wherein the lower ejector retainer plate (11) and the upper ejector retainer plate (10) are arranged on the lower fixed plate (12) from bottom to top, a male mold (8) is arranged above the upper ejector retainer plate (10), a female mold (2) is arranged on the male mold (8), the upper fixed plate (1) is arranged on the female mold (2), oblique guide pillars (6) are bilaterally symmetrically arranged in chambers of the female mold (2) and the male mold (8), sliders (4) are arranged on the oblique guide pillars (6), a male mold core (7) is arranged in a chamber formed between the underside of the sliders (4) and the male mold (8), a female mold core insert (3) is arranged in a chamber formed between the upside of the sliders (4) and the female mold (2), and the center position of the upper end of the female mold core insert (3) is communicated with the hot sprue bushing (13) on the upper fixed plate (1). According to the electric tool motor base mold, the size accuracy and the concentricity and roundness with a stator can be ensured.
Description
Technical field
The utility model belongs to the electro-motor technical field, particularly relates to a kind of electric tool motor base mould.
Background technology
Develop rapidly along with modern industry, the power set of all parts of the world family expenses and garden tool set have more and more adopted electronic series products, in use noise is little, power good, performance is good and the life-span is long in order to guarantee electric tool, this is to the service property (quality) of electronic series products and having higher requirement of life-span, such as motor base armature chamber and motor stator to there be accurately cooperating of concentricity and out of roundness, and consider the draw taper of mould during the armature chamber of traditional design motor base, routine is to be put into 0.5 spend above demoulding angle, can cause like this assembling at present tight top can the becoming flexible even rock of face with stator, can not guarantee concentricity.
We break this outmoded conventions now, fix stator with many reinforcements during design, and reinforcement comes sectional making with zero draw taper.And guarantee that the out of roundness tolerance of reinforcement is ± 0.05MM。
The utility model content
Technical problem to be solved in the utility model provides a kind of electric tool motor base mould, can guarantee the installation accuracy of product.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric tool motor base mould is provided, comprise upper mounted plate, master tooling, mother module core enters son, slide block, wear-resistant block, Angle Pin, male die core, male mould, screw, upper ejector retainner plate, lower ejector retainner plate, bottom plate, hot purt is chewed, lower ejector retainner plate and upper ejector retainner plate are installed above the described bottom plate from top to bottom, and upper ejector retainner plate top is equipped with male mould, and master tooling is installed on the male mould, upper mounted plate is installed above the master tooling, left-right symmetry is equipped with Angle Pin in master tooling and the male mould cavity, and slide block is installed on the Angle Pin, in the cavity that forms with male mould below the slide block male die core is installed, in the cavity that forms with master tooling above the slide block mother module core is installed and enters son, mother module core enters center, son upper end and chews with the hot purt on the upper mounted plate and be communicated with.
By screw male die core is installed in the cavity that forms with male mould below the described slide block.
On the described lower ejector retainner plate thimble is installed.
Beneficial effect
The utility model can guarantee that the accuracy of size reaches and concentricity and the out of roundness of stator.
Description of drawings
Fig. 1 is the utility model front view.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, a kind of electric tool motor base mould comprises upper mounted plate 1, master tooling 2, mother module core enters son 3, slide block 4, wear-resistant block 5, Angle Pin 6, male die core 7, male mould 8, screw 9, upper ejector retainner plate 10, lower ejector retainner plate 11, bottom plate 12, hot purt chews 13, and lower ejector retainner plate 11 and upper ejector retainner plate 10 are installed above the described bottom plate 12 from top to bottom, upper ejector retainner plate 10 tops are equipped with male mould 8, master tooling 2 is installed on the male mould 8, upper mounted plate 1 is installed above the master tooling 2, left-right symmetry is equipped with Angle Pin 6 in master tooling 2 and male mould 8 cavitys, slide block 4 is installed on the Angle Pin 6, in the cavity that forms with male mould 8 below the slide block 4 male die core 7 is installed, in the cavity that forms with master tooling 2 above the slide block 4 mother module core is installed and enters son 3, mother module core enters center, sub 3 upper end and chews 13 with the hot purt on the upper mounted plate 1 and be communicated with.
By screw 9 male die core 7 is installed in the cavity that forms with male mould 8 below the described slide block 4.
On the described lower ejector retainner plate 11 thimble is installed.
It is round to consider that the after-contraction of plastic cement products behind the mould molding is directed at the out of roundness of muscle position on the product, the theoretical value of muscle position size and the deviation of actual value, the EDM special fixture of our special special use, for deviate die is fixed on the tool with different angle (50 ℃/25 ℃/15 ℃) trace that discharges and adjusts size, break through at processing mode.With the accuracy that guarantees size and with concentricity and the out of roundness of stator.
