Abstract
The invention relates to the field of automobile part production, in particular to an automobile buckle manufacturing method. The automobile buckle manufacturing method comprise the steps of raw material selection, raw material drying treatment, die installation, material feeding, product injection molding, separation and packing according to weight. A needed raw material is ABS. The automobile buckle manufacturing method has the beneficial effects that since the ABS is non-toxic and odorless and is light yellow or white opaque particles, formed plastic parts have the good gloss density of 1.02-1.05g/cm<2>; and mass production of buckles can be achieved through the manufacturing method, and the requirements of automobile production are met.
Description
Technical field
The present invention relates to auto parts production field, the specifically preparation method of car bayonet catch.
Background technology
Automotive upholstery is coated on the decoration in body of a motor car, and automotive upholstery has door-plate made of plastic, pressure
Bar, pedal box etc..These plastics interior trim experiences are used in the connection matching between vehicle body medial surface and plastics inside gadget lateral surface
Part is connected on vehicle body, and connector has positioning to be connected in the deck of plastics inside gadget lateral surface, the card on body of a motor car medial surface
Control and one end other end that can be connected with deck can insert the plastic buckle of automobile interior trim parts of hole clipping, and plastic buckle of automobile interior trim parts is
Plastic injection product.So the generation of the preparation method of car bayonet catch significant to the production of car bayonet catch so as to raw
Product has sample, has very big reference value.
Content of the invention
It is an object of the invention to provide the preparation method of car bayonet catch.
For realizing such purpose, the technical scheme is that：Using the injection molding technology of advanced science, by controlling
Injection temperature and the of a relatively high plastic buckle of time production quality, the specific implementation step of the method is：
1) selection of raw material, this injection selects ABS；
2) raw material drying is processed, and for reaching the gloss that product requirement reaches, will be dried before injection；
3) installation of mould, will verify installation site it is ensured that installation site is correct during installation repeatedly；
4) input of material, using motor, absorbing material enters material bin, is ready for next procedure；
5) injection of product：Carry out the injection of workpiece using injection machine；
6) separate, using seperator, the part after injection is carried out separating, so that connecting rod is separated with buckle.
7) weight packaging：Carry out weight packaging using racking machine.
The preparation method of described car bayonet catch is it is characterised in that the requirement that is dried of described raw material is：Winter 7676～
Less than 80 DEG C, 2～3h is dried, summer rainwater sky, below 80～92 DEG C, is dried 4～8h.
The preparation method of described car bayonet catch is it is characterised in that plasticization temperature 230 DEG C～260 during the injection of described product
DEG C, injection pressure is 60MPa-100MPa, injection molding machine nozzle temperature, and 170 DEG C -180 DEG C is benefit, and after the completion of injection, cool time is
80s-150s.
The beneficial outcomes of the present invention：Because ABS is nonpoisonous and tasteless, it is material in slightly yellow or White-opalescent, the moulding of shaping
It is 1.02～1.05g/cm2 that part has preferable gloss density, and this kind of production method can produce buckle in a large number simultaneously, meets
Auto-producing demand.
Specific embodiment
Embodiment 1
The preparation method of car bayonet catch, methods described step is：
1) selection of raw material, this injection selects ABS；
2) raw material is dried with process, the drying before injection：Winter, below 80 DEG C, is dried 2h, and summer rainwater sky exists
Less than 92 DEG C, 5h is dried, such as product will reach special gloss or product itself is more complicated, and drying time is longer, reaches 10h.
Preferably the hopper of board is repacked into hot blast hopper dryer, in order to avoid dried ABS moisture absorption once again；
3) installation of mould, will verify installation site it is ensured that installation site is correct during installation repeatedly；
4) input of material, using motor, absorbing material enters material bin, is ready for next procedure；
5) injection of product：
(1) injection temperature：Plasticization temperature (temperature range of suitable processing, such as 230 DEG C)；
(2) injection pressure：ABS melts ratio of viscosities polystyrene or the MPS height of part, so adopting in injection
With higher injection pressure 80MPa；
(3) injection time：ABS material adopts medium injection speed effect preferably, and when injection speed is too fast, plastics easily burn
Or decompose precipitation vapour, thus welded side seam, general control are occurred on product in 70s；
(4) mold temperature：The forming temperature of ABS is of a relatively high, and mold temperature is also of a relatively high.The general mould temperature that adjusts is 80
DEG C, when production has larger projected area product, 75 DEG C of cover half temperature requirement, 55 DEG C of dynamic model temperature requirement, larger injecting
, configuration is complicated, the product of thin-walled when, be considered as special mould being heated.In order to shorten the production cycle, maintain mold temperature
Relatively stable, after product takes out, can using cold bath, hot bath or other mechanical typing methods compensate original in die cavity
Freeze off the time of sizing；
(5) doses controls：During general injection machine note ABS plastic, the 75% of its per injection amount only up to standard injection amount, be
Raising parts quality and dimensionally stable, lustrous surface, tone uniformly it is desirable to injection volume is to demarcate the 50% of injection volume to be
Preferably；
(6) nozzle temperature, 175 DEG C is benefit；
(7) cool time：After the completion of injection, cool time is 80s
6) separate, using seperator, the part after injection is carried out separating, be that connecting rod is separated with buckle.
7) weight packaging：Carry out weight packaging using racking machine.
The foregoing is only embodiments of the invention, not thereby limit the present invention the scope of the claims, every using this
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
