Abstract
The utility model discloses a four lamella mandrel structures of foam mould, it adds to be equipped with fourth lamella mandrel on the third lamella mandrel of mould, and the telescopic link and the fourth lamella mandrel of cylinder are connected, drive fourth lamella mandrel and third lamella mandrel relative motion, realize the compound die and divide the mould, after moulding plastics, fourth lamella mandrel forms the air pipe of seat. The exhaust can be realized through the die joint of fourth lamella mandrel and third lamella mandrel to the gas that produces around the foaming complex construction in the foaming process to solved dark hole and scarce material problem, made a qualification rate of this region foam bring up to more than 95% by 0.
Description
Technical field
The utility model relates to a kind of pintongs core mold structure of foam mold.
Background technology
In recent years, along with the raising that people require seat comfort, the front-row seats of a lot of high-grade car is provided with air-conditioning heating, ventilation function, just need like this to increase ventilation duct structure on foam, after increasing aeration structure, foam B surface just becomes very complicated, and this region zero-fault of quality criteria requirements is without repairing.Mould is before employing three lobe mode structure, that is: mould adopts the additional 3rd lobe core of upper die and lower die, and the foam that this mould structure is produced can exist a large amount of dark hole and lack material phenomenon around ventilation duct structure, has a strong impact on foam quality.
Summary of the invention
The purpose of this utility model is the problems referred to above existed to solve three lobe mode structure moulds, and provides a kind of pintongs core mold structure of foam mold.
The utility model is equipped with pintongs core on the 3rd lobe core of mould, and the expansion link of cylinder is connected with pintongs core, drives pintongs core and the 3rd lobe core relative motion, realizes matched moulds and parting; After injection moulding, pintongs core forms the ventilation shaft of seat.
The course of work of the present utility model and principle:
Pintongs core under the drive of cylinder with the 3rd lobe core matched moulds, then foam in die cavity, pintongs core pintongs core forms the ventilation shaft of seat, and the gas produced around foaming piece labyrinth in foaming process can realize exhaust by the die joint of pintongs core and the 3rd lobe core.
The beneficial effects of the utility model:
The gas produced around foaming piece labyrinth in foaming process can realize exhaust by the die joint of pintongs core and the 3rd lobe core, thus solves dark hole and scarce material problem, makes the first-time qualification rate of this region foam bring up to more than 95% by 0.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is the back side of the present utility model schematic perspective view.
Fig. 3 is pintongs core schematic perspective view of the present utility model.
Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, the present embodiment is equipped with pintongs core 2 on the 3rd lobe core 1 of mould, the expansion link of two cylinders 3 is connected with pintongs core 2, drives pintongs core 2 and the 3rd lobe core 1 relative motion, realizes matched moulds and parting; After injection moulding, pintongs core 2 forms the ventilation shaft of seat.
The course of work of the present embodiment and principle:
Pintongs core 2 under the drive of cylinder 3 with the 3rd lobe core 1 matched moulds, then foam in die cavity, pintongs core 2 pintongs core 2 forms the ventilation shaft of seat, the gas produced around foaming piece labyrinth in foaming process can realize exhaust by the die joint of pintongs core 2 and the 3rd lobe core 1, thus solve dark hole and scarce material problem, make the first-time qualification rate of this region foam bring up to more than 95% by 0.
