Plate and the cover half are additionally provided with sealing core-pulling mechanism, and the sealing core-pulling mechanism includes sealing core-pulling slide block, sealing core pulling
Sliding block is connected by the piston rod of oil cylinder link block and oil cylinder, and the oil cylinder is mounted in the upper press plates, the hot flow path
Sliding slot is formed in plate and the cover half, the sealing core-pulling slide block is driven by the oil cylinder and slided in the sliding slot, the envelope
It is formed with the plug for the die cavity to be separated into the first color injection molding cavity and the second color injection molding cavity on glue core-pulling slide block, described first
It is provided with the first cast gate in color injection molding cavity, the second cast gate is provided in the second color injection molding cavity.
In above-mentioned technical proposal, multi-stage stairs shape is made in the sealing core-pulling slide block.
Compared with prior art, the injection mold of the utility model, which need to only design a die cavity, can realize double-colored note
Modeling, greatly simplifies the structure of injection mold and injection molding machine, significantly reduces die manufacturing cost and injection molding cost, simultaneously
Injection efficiency is also improved, and has the advantages that processing is simple, easy to maintenance.

Fig. 3 is the attachment structure schematic diagram of oil cylinder and sealing core-pulling slide block in Fig. 1；
Fig. 4 is the a-quadrant partial enlargement structural representation in Fig. 1.
Specific implementation mode
With reference to the accompanying drawings and detailed description, the utility model is described in further detail.As shown in Figs 1-4, it is molded
The single-chamber of mold is molded secondary adhesive sealing mechanism, including the upper press plates 4 of injection molding machine, hot runner manifold 3 and dynamic model 1 and cover half 2, institute
It states and forms die cavity 8, the upper press plates 4, the hot runner manifold 3 and the cover half after being molded between dynamic model 1 and the cover half 2
2 are additionally provided with sealing core-pulling mechanism.
The sealing core-pulling mechanism includes sealing core-pulling slide block 5, and sealing core-pulling slide block 5 passes through oil cylinder link block 6 and oil cylinder 7
Piston rod 71 connect, the oil cylinder 7 be mounted on the upper press plates 4 in, be formed in the hot runner manifold 3 and the cover half 2
Sliding slot, the sealing core-pulling slide block 5 are driven by the oil cylinder 7 and are slided in the sliding slot, be formed on the sealing core-pulling slide block 5
Plug 51 for the die cavity 8 to be separated into the first color injection molding cavity 81 and the second color injection molding cavity 82, the first color injection molding cavity
The first cast gate 21 is provided in 81, the first cast gate 21 is used to inject the first color fused raw material of dual-color plastic product, described
The second cast gate 22 is provided in second color injection molding cavity 82, another color that the second cast gate 22 is used to inject dual-color plastic product is molten
Melt raw material.
The course of work of the utility model is as follows：After molding, die cavity 8, the piston of oil cylinder 7 are formed between dynamic model 1 and cover half 2
Bar 71 extends, and the plug 51 for pouring core-pulling slide block 5 is driven to enter die cavity 8, and die cavity 8 is separated into respectively independent close by rear plug 51 in place
The the first color injection molding cavity 81 and the second color injection molding cavity 82 of envelope, then the first cast gate 21 start to inject into the first color injection molding cavity 81 double
The first color fused raw material of color plastic products；Wait for the first color part injection molding completion of dual-color plastic product and cooling
Afterwards, the piston rod 71 of oil cylinder 7 is shunk, and drives the plug 51 for pouring core-pulling slide block 5 to exit die cavity 8, until plug 51 exits mould completely
After chamber 8, the second cast gate 22 starts to inject another color fused raw material of dual-color plastic product into the second color injection molding cavity 82, directly
It is molded completely to dual-color plastic product.
It can thus be seen that the injection mold of the utility model, which need to only design a die cavity, can realize double-shot moulding,
The structure for greatly simplifying injection mold and injection molding machine significantly reduces die manufacturing cost and injection molding cost；While from
The fused raw material for injecting second of color is arrived after having injected the fused raw material of the first color, mold is not needed and is rotated, it is few
One procedure, shortens injection cycle, therefore improve injection efficiency.
In above-mentioned technical proposal, multi-stage stairs shape is made in sealing core-pulling slide block 5, and three-level step is made in wherein the present embodiment,
As shown in figure 3,51 segment thickness of uppermost plug of sealing core-pulling slide block 5 is minimum, thickness gradually increases successively down, design
Purpose at this structure is to increase the intensity of sealing core-pulling slide block 5.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, should all be fallen into the scope of protection of the utility model.
