Cold and hot water circulation is remake after the full cold water of storage, when mould normally produces, mandrel temperatures can ensure that below 30 DEG C injecting products exist
The size of the part of internal diameter, out-of-roundness, and the receipts on interiors of products surface can be ensured in mould in whole injection moulding process
Contracting warpage, this is one of emphasis reason as the sizing of product internal diameter.
Compared with prior art, the beneficial effect of technical solutions of the utility model is：The utility model discloses a kind of electric smelting
Saddle leads directly to mould, including upper cores, lower die, the first core and the second core, and first core and the second core are set
In the die cavity that upper cores and lower die surround, the first core and the second core coordinate assembly and connection and fixed by stud, on
Gum-injecting port is provided with die, gum-injecting port is communicated to the die joint between upper cores and lower die by glue injection channel, after assembling
The first core and the second core and upper cores between die cavity be used to being molded electric smelting saddle type and lead directly to product, the after assembling
Die cavity between one core and the second core and lower die is used to be molded the straight-through product of another electric smelting saddle type.Gum-injecting port is communicated to
The die joint of mould has the following effects that：Because the weld mark of product is also on die joint, product exhaust utilizes mold parting surface
Gap, reach overall sufficiently exhaust, many exhaust drops can be saved from another perspective, mould is reduced processing
Amount；Because product is that a kind of one-to-two electric smelting saddle type is led directly to, therefore the weld mark of product overlaps with cut-off rule, the product after segmentation
Be not in weld mark, the quality of product is ensured.

Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；
In order to more preferably illustrate the present embodiment, some parts of accompanying drawing have omission, zoomed in or out, and do not represent actual product
Size；
To those skilled in the art, it is to be appreciated that some known features and its explanation, which may be omitted, in accompanying drawing
's.
The technical solution of the utility model is described further with reference to the accompanying drawings and examples.
Embodiment 1
As Figure 1-5, a kind of electric smelting saddle type leads directly to mould, including upper cores 1, lower die 2, the first core 3 and second
Core 4, in the die cavity that the core 4 of the first core 3 and second is arranged at upper cores 1 and lower die 2 surrounds, the He of the first core 3
Second core 4 coordinates assembly and connection and fixed by stud 5, gum-injecting port is provided with upper cores 1, gum-injecting port passes through glue injection channel
The die joint being communicated between upper cores 1 and lower die 2, between the first core 3 and the second core 4 and upper cores 1 after assembling
Die cavity be used to being molded electric smelting saddle type and lead directly to product 6, between the first core 3 and the second core 4 and lower die 2 after assembling
Die cavity be used for be molded another electric smelting saddle type lead directly to product 6.
The gum-injecting port is arranged at the upper surface of upper cores 1, and is communicated to upper cores 1 and lower die by glue injection channel
Die joint between 2.
Gum-injecting port is communicated to the die joint between upper cores 1 and lower die 2 by glue injection channel, has the following effects that：By
In product weld mark also on die joint, product exhaust reaches overall sufficiently exhaust using the gap of mold parting surface, from
Another angle, which is seen, can save many exhaust drops, mould is reduced processing capacity；Because product is a kind of one-to-two electric melting saddle
Type is led directly to, therefore the weld mark of product overlaps with cut-off rule, and the product after segmentation is not in weld mark, and the quality of product is able to
Ensure.
As shown in figure 3, the inside of 3 and second core of the first core 4 is provided with water-cooling system, water-cooling system includes connecting successively
Logical cold water inlet 7, water-cooling channel and hot water outlet 8, cold water inlet 7 are less than hot water outlet 8.Water-cooling system ensures
Cold and hot water circulation is remake after the full cold water of core interior energy storage, when mould normally produces, mandrel temperatures can ensure below 30 DEG C, note
Molding product can ensure the size of the part of internal diameter, out-of-roundness, and interiors of products in mould in whole injection moulding process
The contraction warpage on surface, this is one of emphasis reason as the sizing of product internal diameter.
It is as follows that the utility model electric smelting saddle type leads directly to mold working principle：
Step 1：Mould is first installed to suitable injection molding machine, opens mould, 2 electric smelting hot plates are placed in die cavity.
Step 2：First core 3 and the second core 4 are first installed by 4 studs 5 and spliced, ventilation detection is internal to be
It is no exist block, check it is errorless after in the core that assembles suspension ring are installed, core is put into mould using loop wheel machine, mold cores with
Mold cavity connects cold water by installation screens in cold water inlet 7.
Step 3：The product for completing injection is taken out together with mold cores, cooling pond is put into and integrally cools down, is cooled down
Core is taken apart taking-up product after 12 hours, product size and out-of-roundness etc. are finalized the design almost, and product is finally put into baking oven（70
DEG C, 5 hours）Make stock processing after all residual stress are all discharged, segmentation is just taken out after having order.
Same or analogous label corresponds to same or analogous part；
Term the being given for example only property explanation of position relationship described in accompanying drawing, it is impossible to be interpreted as the limitation to this patent；
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
