Axially vertical two fracture of second sprue groove 22.Mold insert through-hole 23 is with the central axis of the second sprue groove 22
Axial symmetry.
It is the cross-sectional view of rear cavity and inlaid piece of mould incorporated by reference to Fig. 2 to Fig. 9, Fig. 5, Fig. 6 is the schematic diagram of inlaid piece of mould, figure
7 be the schematic diagram of the first mold insert, and Fig. 8 is the schematic diagram of the second mold insert, and Fig. 9 is the ground plan of rear cavity.As shown in Fig. 2 to Fig. 9,
At least one set of inlaid piece of mould 3 in the present embodiment is specially two groups.Two groups of inlaid piece of mould 3 are embedded at two of rear cavity 2 respectively
In mold insert through-hole 23.Splice respectively in a side edge of two type chamber boss 21, single group the two sides of one end of single group inlaid piece of mould 3
The other end of inlaid piece of mould 3 is connected in the bottom surface of rear cavity 2.Single group group inlaid piece of mould 3 includes the first mold insert of opposite split
31 and second mold insert 32.The end surface of first mold insert 31 is equipped with third sprue groove 311 and two the second runner grooves
312, two the second runner grooves 312 are the setting of center axial symmetry with third sprue groove 311,31 one end of the first mold insert
Port recess 313 is poured equipped with two first, single first pours the input terminal of port recess 313 and single second runner groove 312 company
It is logical.The end surface of second mold insert 32 is equipped with the 4th sprue groove 321 and two third runner grooves 322, two thirds
Runner groove 322 is the setting of center axial symmetry with the 4th sprue groove 321, and 32 one end of the second mold insert is equipped with two the
Two pour port recess 323, and the single second input terminal for pouring port recess 323 is connected to single third runner groove 322, and is corresponded to
Single first pours port recess 313.
Specifically, the first mold insert 31 and the opposite split of the second mold insert 32 are formed into single group inlaid piece of mould 3, in the first mold insert 31
Third sprue groove 311 and the second mold insert 32 in 321 split of the 4th sprue groove formed the 5th sprue groove
35, the 5th sprue groove 35 splices in the incision position of the second sprue groove 22, and the second sprue groove 22 has been spliced
It is whole, to form the sprue being continuously closed with 12 split of the first sprue groove.31 two second shuntings in first mold insert
Road groove 312 forms two the 4th runner grooves with two 322 splits of third runner groove in the second mold insert 32 respectively
36, two the 4th runner grooves 36 form two runners with two 13 splits of the first runner groove in front cavity 1.The
Two first in one mold insert 31 are poured port recess 313 and pour 323 split shape of port recess with two second in the second mold insert 32 respectively
At two cast gates 33, the input terminal of two cast gates 33 is connected to two runners respectively, and the output end of two cast gates 33 distinguishes position
In two type chamber boss 21 a side along and correspond to two type chamber grooves 11.One shares two groups of inlaid piece of mould in the present embodiment
3, then four runners and four cast gates can be formed altogether, one end of each runner is connected to sprue, the other end and one
A cast gate connection.
When injection molding, the plastic particles of molten condition flow successively through sprue, runner and cast gate, finally by cast gate
33 output end separately flows into and fills up two type chambers, and the plastic particles of molten condition are formed final in the intracavitary cooling and shaping of type
Finished product.Finished product is its medial surface by the one side of plesiotype chamber boss 21, and the one side by plesiotype chamber groove 12 is its outer surface, and is poured
The output end of mouth 33 corresponds to the medial surface of product.The medial surface of product is arranged in rather than outer surface in the output end of cast gate 33, makes
Product external surfaces are obtained without the remaining injection molding trace of cast gate 33, optimize the appearance of product, eliminate subsequent secondary operation processing
Work, improve production efficiency, save cost of labor.Meanwhile because cast gate 33 is located at the inside of inlaid piece of mould 33, cast gate 33
The connection of the medial surface of output end and product, opens front cavity 1, condensate when finished product is ejected from rear cavity 2, in cast gate 33
The pulling force ejected outward by one, the pulling force to generate shearing between the condensate and inlaid piece of mould 33 of 33 output end of cast gate
Power, which cuts off the condensate in cast gate 33 from the position of the output end of cast gate 33, so that finished product individually be ejected.Cast gate
Condensate is cut off with the ejection of finished product, the work that subsequent artefacts trim cast gate is eliminated, to improve production efficiency and save
Human cost.Preferably, cast gate 33 is ox horn type.Further, the output end size of cast gate 33 by original long 1.2mm ×
Wide 1.0mm change growth 6.0mm × wide 0.6mm, increases the area of output end, the plastic particles for accelerating molten condition are flowing
Glue speed is walked in road, shortens the molding cycle of entire product, to improve production efficiency.
Further, the side of the other end of the first mold insert 31 in each inlaid piece of mould 3 and the second mold insert 32 is set respectively
There is spacing block set 34；The bottom surface of rear cavity 2 is equipped with two limiting grooves 24, and the side of each limit limiting groove 24 and mold insert are logical
Hole 23 is connected to and is located at the side of inlaid piece of mould 3；Spacing block set 33 is connected in limiting groove 24, prevents inlaid piece of mould 3 in mold insert
It is slided in through-hole 23, plays the role of that limit is fixed to inlaid piece of mould 3.
Still further, the side of two limiting grooves 24 is additionally provided with blind hole 25, blind hole 25 is connected to simultaneously with limiting groove 24
Positioned at the side of spacing block set 33.When worker takes out inlaid piece of mould 3 from mold insert through-hole 23, worker can be grabbed by blind hole 25
Inlaid piece of mould one end is got, more easily to take out inlaid piece of mould 3 from the mold insert through-hole 23 in rear cavity 2.
Further, front cavity 1 further includes multiple positioning grooves 14, and multiple positioning grooves 14 are located at type chamber groove
11 side；Rear cavity 2 further includes multiple locating convex blocks 25, and multiple locating convex blocks 25 are located at the side of type chamber boss 21,
And correspond respectively to multiple positioning grooves 14.Multiple positioning grooves 14 are abutted against with multiple locating convex blocks 25 respectively, so that preceding mould
Relatively-stationary gap is kept when type chamber groove 11 in benevolence 1 and type chamber 21 split of boss in rear cavity 2, to guarantee
The stabilization of type chamber.
In conclusion cast gate is arranged in the inlaid piece of mould of rear cavity the injection mold of the application, when demolished,
While thimble ejecting product, the condensate in cast gate can generate shearing, automatic cutting with inlaid piece of mould.The automatic cutting of cast gate,
The process for saving artificial later period trimming cast gate, improves production efficiency and has saved human cost.Meanwhile the position setting of cast gate
In a side edge of the type chamber boss of rear cavity, and correspond to front cavity type chamber groove so that cast gate with it is formed after injection molding
The junction of product is located at the inner surface of product.Middle cast gate is directly overlapped in for product external surfaces compared with the existing technology,
Product external surfaces after improvement are smooth, improve the appearance of product, avoid the subsequent secondary operation to gate vestiges, improve
Production cost is also saved while production efficiency.
