Description
Technical field
The utility model belongs to technical field of mold, more particularly to a kind of mould structure of the eccentric rolling muscle of special container.
Background technology
In stainless steel cool-bag product, steel part shell is generally using materials in the tube water swelling with welding midsole, the work at press-fitting steel bottom
Skill, the process that this technological requirement steel part shell has one of bottom rolling muscle before midsole is welded, to reach good appearance fiting effect,
Therefore the size and appearance of outer casing bottom rolling muscle be must be strictly controlled.
Conventional outer casing bottom rolling muscle processing mold is as shown in Figure 1：Outer casing bottom is put into mould downward, makes the periphery at bottom
It is in contact with bottom plate C, and as positioning.At the beginning of being put into, design point is that there was only bottom and bottom plate C be to completely attach to shell
, with oral area support wheel A and rolling muscle lubrication groove B all there are larger gap, this is discontiguous.This mentality of designing, shell can
Left-right and front-back is arbitrarily mobile in a mold and left-right and front-back is overturn by a small margin, i.e., mould does not put down shell in X-axis, Y direction
The free degree of shifting and limited around X-axis, the rotating free degree of Y-axis.After placing shell, start machine, main shaft rotation, rolls muscle
Foreign steamer D is elapsed to the right shell until outer casing inner wall is in contact with rolling muscle lubrication groove B to the right close to shell.Muscle foreign steamer is rolled at this time
D is mutually rotated and extruded with rolling muscle lubrication groove B, and the processing of size and dimension is carried out to bottom muscle.But in the shell under machining state
Wall is with being completely discontiguous on the right side of oral area support wheel A and on the right side of rolling muscle lubrication groove B, i.e., shell is vacant state, such as Fig. 1 here
Shown in right side.Since mold body does not limit 4 frees degree of shell, shell hanging part is very big in addition, causes outer
Shell state labile in process, the bottom muscle size and dimension processed is unstable, even has two at same position
Bar bottom muscle is processed out, this strong influence aesthetics of product, reduces production qualification rate.
Utility model content

Embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing：As shown in attached drawing 2,3,8, the utility model includes
Main shaft 7, rolling muscle lubrication groove 6, roll muscle foreign steamer 10, is placed with the first stepped groove that 7 body of main shaft is equipped with rolling muscle
Wheel 6, and locked with locking nut 5；The top of locking nut 5 is provided with flat mat 4；Set by 7 upper end of main shaft
Locating wheel 3 is placed with the second stepped groove having, and is fixed with pressing plate 9；When shell 11 is put into mould, the shoulder of shell 11 is with determining
The shoulder having set by the 3 outer end surface sides of wheel of position is in contact, and compresses housing shoulder with top 1.When shell is processed (as shown in Figure 3),
Muscle foreign steamer 10 is rolled to the right close to shell 11, and shell 11, top 1 and locating wheel 3 are elapsed to the right together.When locating wheel 3 and master
When axis 7 is in contact, overall movement to the right stops.At this time, 11 bottom interior surface of shell is in contact with rolling muscle lubrication groove 6,
Roll muscle foreign steamer 10 and under the common extruding of rolling muscle lubrication groove 6, bottom muscle is gradually molded and reaches required size.
The shoulder having set by the 3 outer end surface side of locating wheel is equal with the shoulder of 11 oral area of shell, and outside
11 shoulder of shell and 3 shoulder of locating wheel are complete plane contact, and as positioning datum, there is certain interval at other positions, positioning
Wheel 3 plays the role of positioning product, and in the operating condition, locating wheel 3 moves right at the same time with shell 11, but both one
Straight to be held against state, no vacant state produces.This causes, locating wheel 3 is to translation of the product in X, Y, Z axis and around X, Y-axis
Rotation limit, i.e., locating wheel 3 has carried out product the limitation of 5 frees degree, remains rotating automatic degree about the z axis.
The rolling muscle foreign steamer 10 is located at the side of rolling muscle lubrication groove 6, and in the same plane；When shell 11 is processed,
Roll muscle foreign steamer 10 and rolling 6 phase of muscle lubrication groove extruding.
The pressing plate 9 is fixed on 7 upper end of main shaft by screw 2.
7 lower end of main shaft is fixed with mould bases 8 by welding manner.
As shown in Figure 2, when each part is except the central axis of rolling muscle foreign steamer 10 is when on the same line, the positioning
The distance between the M faces (such as Fig. 4) on L faces (such as Fig. 4) and main shaft 7 on wheel 3 E (such as Fig. 4) and 11 inner surface of shell and rolling muscle
The distance between 6 corresponding face of lubrication groove J (such as Fig. 2) unanimously, i.e. E=J, and relative error≤0.1mm.This design, ensure that
When locating wheel 3 is contacted with main shaft 7, shell is just pressed in shaping position by rolling muscle foreign steamer 10 with rolling muscle lubrication groove 6.Work as manufacture
When controllable relative error occurs in process, shadow of the error to bottom muscle shape and size can be eliminated by the pliability of material in itself
Ring.
As shown in Figure 2,7 on the N faces (such as Fig. 4) in the locating wheel 3 and main shaft on O faces (such as Fig. 4) between
Distance F (such as Fig. 4), must be more than distance E, i.e. F ＞ E.During actual processing, there are mismachining tolerance, in order to ensure F ＞ E this
Condition, takes F values must big more than E values 0.5mm, i.e. F-E ＞ 0.5；Before this design can ensure that L faces are contacted with M faces, N is avoided
Face contact with O faces, so as to ensure that L faces can be contacted with M faces with 100%.
As shown in Figure 2, the upper surface of the locating wheel 3 exists with the distance between the lower surface of pressing plate 9 H (such as Fig. 5)
Between 0.1mm to 0.2mm；The lower surface of the locating wheel 3 is arrived with the distance between flat mat 4 I (such as Fig. 6) in 0.1mm
Between 0.2mm；This design can allow locating wheel or so to move freely, but not there is a situation where locating wheel is acutely swung.
When shell 11 enters machining state, the L faces of locating wheel 3 are in contact with the M faces of main shaft 7, as shown in Fig. 3 states.
Due to L faces and M faces in original state there are larger gap, when in order to make L faces contact M faces, locating wheel 3 will not hang
The situation of sky work, the P faces in locating wheel 3 are with the R faces on main shaft 7 under Fig. 3 states, and right contact face minimum range K is (as schemed
7) 0 must be more than, due to there are mismachining tolerance, usually choosing K ＞ 0.5mm.
The utility model is not limited to the above embodiment, makees any change no matter being formed in its shape or material, all
It is to use structure design provided by the utility model, is all a kind of deformation of the utility model, is considered as new in this practicality
Within type protection domain.
