Sprue gate mold insert provided by the invention is used for injection mold, especially suitable in the injection mold of plastic part.
As shown in Figure 1, sprue gate mold insert 1 provided by the invention includes mold insert main body, the mold insert body interior formation is poured
Note channel, it is preferable that the mold insert main body includes split settings first part 11 and second part 12,11 He of the first part
The symmetrical configuration of second part 12, the first part 11 and second part 12 mutually abut and form the sprue gate mold insert 1, and
The cast channel is formed between the first part 11 and second part 12.
It describes in detail below to its concrete structure by taking first part 11 as an example.As shown in Figure 2,3, the first part
11 include main body 111, and the main body 111 is configured to block structure, and the block structure includes fitting surface 112, the fitting surface
112 fitting surfaces opposite on the second part 12 are in close contact.Pouring basin 113 is formed on the fitting surface 112, it is described to pour
Note slot 113 is arranged on the top of the fitting surface 112, and the pouring basin 113 is configured to curved shape, for example, ox horn shape or perfume (or spice)
Any of several broadleaf plants shape.Pouring basin after the first part 11 and second part 12 splice in first part 11 and second part 12 is spliced to form
Closed cast channel in the circumferential, the cast channel are in ox horn or banana-shaped.Preferably, the cast channel is in figure 3
Shown in size in upper and lower directions be less than with the size in upper and lower directions vertical direction, so that the cast channel is formed flat and lead to
Road, further, from input end on the direction of outlet end, sectional dimension is gradually reduced in the cast channel, to facilitate by
One end is demoulded to second end, as shown in figure 4, the side h in the cast channel has certain gradient θ, it is preferable that θ >=4 °.Into
One step, the trough wall surface of the pouring basin 113 is smooth curved surface, to facilitate molding sizing material to be taken out out of described cast channel.
The first end of the pouring basin 113 in the direction of extension is located on the upper side 115 of the first part 11, described
Upper side 115 is vertical with the fitting surface 112, and positioned at the upside of the fitting surface 112.It is formed on the upper side 115
Bulge-structure 114, the bulge-structure 114 is preferably the platform shape structure that upper surface is less than lower face, and side wall is smooth curved surface,
The highly preferred of the bulge-structure 114 is 0.5-1mm.Formation is connected to the pouring basin 113 on the bulge-structure 114
Gap 116, the gap 116 constitute the outlet of the pouring basin 113, i.e. gap on two parts docks to form the cast
The sizing material in channel exports, it is preferable that it is vertical with the fitting surface 112 that the size of the gap 116 in the lateral direction is less than it
Size on direction so that the gap 116 forms squashed structure, as shown in figure 4, the length dimension of sizing material outlet is a,
The value range of a is 3-8cm, and the value range of width dimensions b, b are 0.5-1.8cm, and the gap 116 forms squashed structure
The size on its Impact direction (width direction) can be reduced under the premise of ensureing that gap entire area goes out sizing material enough, from
And make to be easier to disconnect with moulding when demoulding.The setting of the bulge-structure 114 is formed after so that moulding is molded at sprue gate
Concave inward structure after demoulding, is recessed at sprue gate on moulding, can be protruded to avoid sprue gate breakpoint and is easy to scrape hand or shadow
The phenomenon that ringing appearance.The second end of the pouring basin 113 is connected to the left side 117 of the main body 111, the pouring basin 113
Second end constitute the input end of the pouring basin 113.Preferably, 117 phase of the upper side 115 of the main body 111 and left side
