Abstract
The utility model discloses a mould pressing formula plug screw mould, this mould are including the last mould, well mould, the lower mould that connect gradually go up and correspond between mould, well mould and the lower mould and be equipped with the copper spare the clearance department between well mould and the copper spare corresponds and is equipped with the die cavity go up the position correspondence that mould and die cavity are linked together and be equipped with the flash ring well mould corresponds with the position that the die cavity is linked together and is equipped with the cutting nozzle. The utility model relates to a mould pressing formula plug screw mould changes three-layer mould into by original four layers mould, and the mould structure is simplified, and production efficiency improves by a wide margin.
Description
Technical Field
The utility model belongs to the technical field of the special mould and specifically relates to a mould pressing formula plug screw mould.
Background
The screw plug is a part which is connected by screw threads to prevent liquid leakage, wherein the screw threads can be standard threads or pipe threads. The existing plug screw mold is a four-layer mold, and the mold has a relatively complex structure and low production efficiency; by adopting the transfer process, a transfer groove, a flow channel, a transfer point and the like consume a large amount of materials; the edges are easy to generate rough edges during molding production, and the cleaning is not good, and the efficiency is low. In order to overcome the defects, a mould pressing type plug screw mould is required to be designed.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, a die pressing type plug screw die is provided.
The utility model discloses a following scheme realizes:
the mould pressing type plug screw mould comprises an upper mould, a middle mould and a lower mould which are sequentially connected, wherein copper pieces are correspondingly arranged between the upper mould, the middle mould and the lower mould, a cavity is correspondingly arranged at the gap between the middle mould and the copper pieces, a material overflowing ring is correspondingly arranged at the position where the upper mould is communicated with the cavity, and a cutting nozzle is correspondingly arranged at the position where the middle mould is communicated with the cavity.
The middle part of the lower die is correspondingly provided with a limiting column protruding towards the middle die, the lower part of the copper piece is correspondingly provided with an inwards-recessed connecting groove, and the limiting column is correspondingly inserted into the connecting groove.
The upper die is provided with a blind hole-shaped top limiting groove correspondingly towards one end of the middle die, and the top of the copper piece is correspondingly inserted into the top limiting groove.
The utility model has the advantages that:
1. the utility model relates to a mould pressing formula plug screw mould changes three-layer mould into by original four layers mould, and the mould structure is simplified, and production efficiency improves by a wide margin.
2. The application changes the original transfer injection process into direct mould pressing, thereby saving the sizing materials of the transfer injection groove and the runner, saving the material consumption and reducing the cost.
3. Add in the mould of this application and mill and lead flash ring and cutting nozzle, the deckle edge that produces during shaping production is connected with this two parts and cutting nozzle together, becomes to tear the overlap and directly tears together and remove, improves production efficiency.
Drawings
Fig. 1 is a schematic structural view of a die-pressing type plug screw die of the present invention;
fig. 2 is a detailed view of the structure of the part a in fig. 1.
In the figure: 1 is an upper die, 2 is a middle die, 3 is a lower die, 4 is a cavity, 5 is a copper part, 6 is a flash ring, 7 is a cutting nozzle, 8 is a limiting column, 9 is a connecting groove, and 10 is a top limiting groove.
Detailed Description
The preferred embodiments of the present invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1 and 2, the die pressing type plug screw die comprises an upper die 1, a middle die 2 and a lower die 3 which are connected in sequence, wherein copper pieces 5 are correspondingly arranged between the upper die 1, the middle die 2 and the lower die 3, a cavity 4 is correspondingly arranged at a gap between the middle die 2 and the copper pieces 5, a flash ring 6 is correspondingly arranged at a position where the upper die 1 is communicated with the cavity 4, and a cutting nozzle 7 is correspondingly arranged at a position where the middle die 2 is communicated with the cavity 4. Add in the mould of this application and mill and lead flash ring and cutting nozzle, the deckle edge that produces during shaping production is connected with this two parts and cutting nozzle together, becomes to tear the overlap and directly tears together and remove, improves production efficiency. The specific dimensions and structure of the copper element 5 are well known in the art and will not be described in detail here.
The middle part of the lower die 3 is correspondingly provided with a limiting column 8 protruding towards the middle die 2, the lower part of the copper part 5 is correspondingly provided with an inwards-recessed connecting groove 9, and the limiting column 8 is correspondingly inserted into the connecting groove 9. The spacing post 8 is matched with the connecting groove 9 correspondingly, so that the stability of the structure can be improved.
Go up mould 1 and correspond the top spacing groove 10 that is equipped with the blind hole form towards the one end of well mould 2, the top of copper spare 5 corresponds inserts top spacing groove 10, effectively prevents that copper spare 5 from removing in process of production. The specific working process and principle of the die are known technology, and are not described in detail herein.
Although the invention has been shown and described in detail with respect to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
