Detailed Description

The utility model provides a manufacturing mould suitable for door plant shell in door. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.

As shown in fig. 1 to 2, the manufacturing mold suitable for the door panel shell in the car door comprises a lower die holder 1, wherein an upper die holder 2 is arranged on the lower die holder 1, and the manufacturing mold is characterized in that: in order to realize synchronous casting and improve the processing efficiency, casting cavities 3 are distributed in the lower die holder 1 in an image mode. Particularly, in order to be favorable to the complete shaping of door plant shell in the door, the casting medium of being convenient for flows through the preset position of die holder 1, is provided with interior door plant shell molding groove 4 in casting die cavity 3. Meanwhile, in order to avoid the phenomenon that the flow of the casting medium fluctuates in a certain period of time, the inside of the casting medium is impacted, and casting dead angles occur due to different cooling temperatures, the overflowing casting medium can be properly discharged and shunted, and a plurality of overflow holes 5 are distributed outside the inner door panel shell modeling groove 4. Considering the convenience of demoulding, unnecessary adhesion between the finished product and the mould can not be caused, the damage of demoulding of the finished product is avoided, and a plurality of demoulding guide structures 9 are distributed outside the adopted inner door plate shell moulding groove 4. Considering during the conventional manufacturing, in order to avoid the inside "meat deficiency" defect that appears of finished product, probably suitable leading-in casting medium more is in order to fill, in order to avoid unnecessary casting medium to cause the unnecessary adhesion of upper die base 2, die holder 1 junction after the cooling, do not influence subsequent mould separation, the utility model discloses at door plant shell molding groove 4 outside turn-on connection have a plurality of main overflow grooves 6 of arranging. In addition, in order to meet the requirement of the convergence of multiple flows at the same time, improve the filling rate of the casting material in unit time and shorten the processing time, a plurality of casting holes 7 are arranged at the position, corresponding to the casting cavity 3, on the upper side surface of the upper die base 2. Also, in order to reduce possible sticking of the mould, secondary overflow troughs 8 are connected between the casting openings 7. Furthermore, in order to realize the double-sided synchronous forming of the door panel outer shell in the vehicle door, a casting inner core is arranged at the position of the lower side surface of the upper die base 2 corresponding to the casting cavity 3. The shape of the casting inner core is matched with the current casting cavity 3, a proper reserved area of a combination structure can be reserved, corresponding processing can be carried out by adopting conventional means in the industry, and details are not repeated.

Combine the utility model discloses an embodiment of preferred sees, considers that the finished product finally needs to go other structures of door and effectively combines, in order to realize the prepositioning during combining, can be including the marginal distribution of door plant shell molding groove 4 has extension to combine limit generating groove 10, is provided with extension expansion groove 14 on the extension combines limit generating groove 10. Like this, can let the finished product outside possess suitable extension joint structure, be convenient for follow-up as the screw links up the reservation limit, need not additionally to add supplementary limit in the assembly, shortened the combination process of follow-up door.

Further, in consideration of smooth demolding after cooling, the demolding guide structure 9 includes a demolding main groove, a plurality of demolding auxiliary grooves extend from the demolding main groove, and the demolding auxiliary grooves are communicated with the edge of the inner door panel outer shell molding groove 4. Therefore, when the finished product is separated from the die, the demolding main groove and the demolding auxiliary groove can meet appropriate stress release, break smoothly when suffering local stress, and do not allow stress to be transmitted to the thinner edge of the door plate, so that the yield of the finished product is improved.

In view of practical implementation, in order to allow the casting medium to smoothly flow in, the casting hole 7 comprises a hole body, and a plurality of buffer grooves 11 are concentrically arranged on the periphery of the hole body. Therefore, the casting medium can be guided by the buffer groove 11, so that the dispersion type introduction similar to spraying is realized, the casting cavity 3 is better filled, and the casting dead angle is avoided.

Furthermore, air possibly mixed in during casting is discharged as soon as possible, unnecessary sand holes are reduced, the tightness of the edge of the shell wall of the inner door panel of the thin car door is improved, no internal hollowing occurs at a thicker structure, and a plurality of communicated exhaust holes 12 can be distributed on the upper die holder 2.

Simultaneously, consider the smooth compound die during processing, avoid the compound die error that probably appears, die holder 1 edge is provided with a plurality of constant head tanks 13, and upper die base 2 corresponds position department and is provided with the locating lever, and when die holder 1 and upper die base 2 combined, the locating lever inserts in the constant head tank 13. Moreover, for some more viscous casting materials, in order to avoid the main overflow groove 6 from being blocked during use and improve the smooth discharge of the excessive casting materials, an expansion groove 14 is arranged on the main overflow groove 6. Therefore, the external space of the main overflow groove 6 is increased, and air cannot enter when the excess materials are discharged outwards.

As can be seen from the above description, the utility model has the following advantages:

The above technical solutions of the present invention have been fully described, and it should be noted that the present invention is not limited by the above description, and all technical solutions formed by equivalent transformation or equivalent transformation adopted by the spirit of the present invention in the aspects of structure, method or function by those of ordinary skill in the art all fall within the protection scope of the present invention.
