Abstract

The invention relates to the technical field of injection moulds, particularly to an injection mould for producing car trim strips. The injection mould comprises a panel, a female die fixing plate, a female die, a male die, a male die fixing plate, a push plate, an ejector retainer plate, an ejector base plate and a base plate which are sequentially arranged from up to down, wherein an abrasion resistant plate is arranged between the female die and the contact side wall of the female die fixing plate; the included angle between the side wall of the female die and the vertical plane is 2 degrees-4 degrees; a plurality of ejection mechanisms used for ejecting the female die are mounted on the ejector retainer plate and the ejector base plate; a plurality of return mechanisms used for returning the female die fixing plate are mounted on the ejector retainer plate; a plurality of return mechanisms used for returning the male die are mounted on the base plate; a heat insulating plate is arranged on each of the upper surface of the panel and the lower surface of the base plate. According to the injection mould, during the production process, the ejection action is smoother, and the product is uniformly stressed and not easy to break, so that the finished product ratio of the product is greatly improved; meanwhile, the mould-closing process is quicker, so that the injection efficiency of the mould is greatly improved.

Description

For the manufacture of the injection mold of automotive trim strip
Technical field
The present invention relates to the technical field of injection mold, especially a kind of injection mold for the manufacture of automotive trim strip.
Background technology
Automobile becomes one of important vehicles of people already, under the prerequisite not changing the function and structure of automobile own, by installing additional or reequiping exterior trimming parts, change the outward appearance of automobile, thus make the more beautiful and fashion of automobile, to meet aesthetic conceptions and the individual demand of people.Automotive trim strip is the class in automobile exterior trim part, and automotive trim strip adds the aesthetic feeling of vehicle body side, and be identical with vehicle body radian, durable is indeformable, meanwhile, provides available protecting to the body paint easily collided with during door contact interrupter.
Injection mold is the instrument producing plasthetics, and the material melted that is heated is injected die cavity by high pressure by it, after cooling curing, obtains formed products.Obviously, injection mold is also one of visual plant of automotive trim strip manufacture, due to the thinner thickness of automotive trim strip, and moulding is complicated, injection mold is very difficult by goods ejection process, usually occurs the phenomenon of bursting goods, greatly reduces the yield rate of goods.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of injection mold for the manufacture of automotive trim strip, overcomes in existing injection mold production process the defect ejecting dyskinesia, bursting goods, reduction goods yield rate.
The technical solution adopted for the present invention to solve the technical problems is: a kind of injection mold for the manufacture of automotive trim strip, have set gradually from top to bottom panel, die block, die, punch, punch retainer, push pedal, face needle plate, end needle plate and base plate; Be provided with wearing plate between the contact sidewall of described die and die block, between the sidewall of die and vertical plane, angle is 2 ° ~ 4 °; Described face needle plate and end needle plate being provided with multiple ejecting mechanism for ejecting die jointly, face needle plate being provided with multiple response agency for replying die block, described base plate being also provided with multiple response agency for replying punch; The upper surface of described panel and the lower surface of base plate are provided with thermal insulation board.
Further restriction, each ejecting mechanism described in technique scheme comprises push rod and is fixedly mounted on the angled slide block at push rod top; Described each response agency comprises spring guide pillar and is set in the back stitching spring on spring guide pillar.
Further restriction, the base plate described in technique scheme is provided with multiple push pedal guide pillar for leading to push pedal.
Further restriction, the end needle plate described in technique scheme is provided with multiple telescopic stop screw for limiting push pedal shift length.
The invention has the beneficial effects as follows: the injection mold for the manufacture of automotive trim strip of the present invention, by common on face needle plate and end needle plate, multiple ejecting mechanism for ejecting die is installed, make to eject action in injection mold production process more smooth and easy, goods uniform force not easily occurs, by the phenomenon of bursting, substantially increasing the yield rate of goods; Simultaneously, by installing multiple response agency for replying die block on the needle plate of face, base plate also being installed multiple response agency for replying punch, making matched moulds process in injection mold production process more quick, substantially increasing the injection moulding efficiency of mould.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
