Abstract
The utility model discloses a kind of improving cavity molds；Including bottom plate, support block, runner ejector pin plate, ejector retainner plate, ejector pin, ejector sleeve, can side template, can side enter block；It is described can side enter block be fixedly mounted on can side template center, can side template be fixedly mounted on bottom plate by support block, the lower end of ejector sleeve is fixed on runner ejector pin plate, the upper end of ejector sleeve protrude into can side enter in block, the lower end of ejector pin is fixed on bottom plate, the upper end of ejector pin be upward through protrude into after ejector sleeve can side enter flowing cooling bath in block；It is described can side enter the top surface of block and be equipped with one and go out four, four runners for going out eight.Since the utility model is equipped with ejector sleeve and ejector pin, position meat thickness most thick in runner is thinned ejector pin；The utility model can side enter the top surface of block and be equipped with one and go out four, the four runner structures for going out eight, the thickness of thickest part is further thinned among runner, and the cooling velocity of runner waste material is fast, high production efficiency, reduces the production cycle of product.
Description
Technical field
The utility model relates to a kind of injection molds, more particularly to a kind of improving cavity mold.
Background technique
Plastics injection mould is the tool for producing plastic products, very widely used.In plastic products injection molding, it is
Meet the needs of moulding process, it is often necessary to while injection molding multiple products, for this purpose, go out more flow passage structures using one,
As shown in Figure 1A, Figure 1B, traditional one, which goes out more flow passage structures, mostly uses eight rice font runners 10, is ejected with thimble 20
Waste material 30, traditional structure need to cool down there are sprue 40 and the material thickness of 10 junction runner waste material 30 of runner are thicker
Time is longer, the lower defect of production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of cooling velocities fastly, the improving cavity mold of high production efficiency.
To achieve the above object, the technical solution of the utility model is:
The utility model is a kind of improving cavity mold；Including bottom plate, support block, runner ejector pin plate, ejector retainner plate, ejector sleeve
Needle, ejector sleeve, can side template, can side enter block；It is described can side enter block be fixedly mounted on can side template center, can side template pass through
Support block is fixedly mounted on bottom plate, and an accommodating space can be being formed between side template and bottom plate；The runner
Ejector retainner plate and ejector retainner plate are all movably arranged in accommodating space, and the lower end of ejector sleeve is fixed on runner ejector pin plate, the upper end of ejector sleeve
Upwards sequentially pass through ejector retainner plate, can side template protrude into can side enter in block, the lower end of ejector pin is fixed on bottom plate, ejector pin
Upper end be upward through protrude into after ejector sleeve can side enter flowing cooling bath in block；It is described can side enter the top surface of block and be equipped with one and go out
Four, four go out eight runner.
The runner includes the first runner, the second runner, third runner；First runner is by four
The interior straight channel of cross setting is constituted, and the inner end of four interior straight channels is connected to sprue；Second runner
For annular channel, inside is connected to the first runner, and outside is connected to third runner；The third runner is by eight
The outer straight channel of item is constituted, and inner end is connected to the second runner, and outer end is connected to type chamber.
After adopting the above scheme, the utility model has the advantage that
1, since the utility model is equipped with ejector sleeve and ejector pin, position meat thickness most thick in runner is thinned ejector pin；
2, due to the utility model can side enter the top surface of block and be equipped with one and go out four, the four runner structures for going out eight, in runner
Between the thickness of thickest part be further thinned, the cooling velocity of runner waste material is fast, high production efficiency, reduces the production of product
Period.
The utility model is further described in the following with reference to the drawings and specific embodiments.
Detailed description of the invention
Figure 1A is the cross-sectional view of existing runner；
Figure 1B is the top view of existing runner；
Fig. 1 is the stereogram exploded view of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
Fig. 3 is the cross-sectional view of the utility model ejector pin and ejector sleeve cooperation；
Fig. 4 is the top view of the utility model runner；
Fig. 5 is the cross-sectional view of the utility model runner.
Specific embodiment
As shown in Figure 1-Figure 3, the utility model is a kind of improving cavity mold；Including bottom plate 1, support block 2, can side enter
Block 3, runner ejector pin plate 4, ejector retainner plate 5, ejector pin 6, ejector sleeve 7, can side template 8.
It is described can side enter block 3 be fixedly mounted on can side template 8 center, can side template 8 be fixedly mounted on by support block 2
On bottom plate 1, an accommodating space can be being formed between side template 8 and bottom plate 2；The runner ejector pin plate 4 and top
Needle plate 5 is all movably arranged in accommodating space, and the lower end of ejector sleeve 7 is fixed on runner ejector pin plate 4, the upper end of ejector sleeve 7 upwards according to
It is secondary pass through ejector retainner plate 5, can protrude into after side template 8 can side enter in block 3, the lower end of ejector pin 6 is fixed on bottom plate 1, ejector sleeve
The upper end of needle 6 be upward through ejector sleeve 7 protrude into can side enter flowing cooling bath 91 in block 3；It is described can side enter the top surface of block 3 and be equipped with
One goes out four, four runners 92 for going out eight.
As shown in Figure 4, Figure 5, the runner 92 includes the first runner 921, the second runner 922, third shunting
Road 923；First runner 921 is made of the interior straight channel that four cross are arranged, the inner end of four interior straight channels
It is connected to sprue 93；Second runner 922 is annular channel, and inside is connected to the first runner 921, outside
It is connected to third runner 923；The third runner 923 is made of eight outer straight channels, inner end and the second runner
922 connections, outer end is connected to type chamber.
Working principle of the utility model is:
As shown in Figure 1, the utility model increases ejector sleeve 7, position meat thickness most thick on runner is thinned ejector pin 6；It is former
Runner 10 is eight rice font runners (as shown in Figure 1B), and thickest part width H1 is 5.23 among the runner of this shape
Millimeter, the position are longer cooling time；As shown in Figure 4, Figure 5, the runner 92 of the utility model is changed to four cross radiation
After type runner, intermediate thickest part width H2 is 3.4 millimeters, and meat thickness reduces obvious.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
Range should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of being covered with new patent.
