Abstract
The utility model discloses a precision injection molding die capable of ventilating inside and relates to the technical field of dies. The precision injection molding die comprises a female die, wherein an injection molding groove is formed in the middle part of the female die; a transverse elongated hole and a vertical hole are formed in the female die; one end of the vertical hole is communicated with the transverse elongated hole, and the other end of the vertical hole is communicated with the injection molding groove; and the air inlet ends of the transverse elongated holes are connected with a ventilating pipe. The inner part of the female die can be ventilated; the forming period of a product is shortened; and unqualified products are reduced.
Description
Technical field:
The utility model relates to technical field of mold, more specifically to the Injection Mold that can ventilate in a kind of mould.
Background technology:
Product in existing mould is generally the external gas blow pipe of mould and blows after injection mo(u)lding, increase molding cycle when this operates in moulding, causes dust, increases defective products.
The utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and the Injection Mold that can ventilate in a kind of mould is provided, and it shortens the formed product cycle by in the master mold internal ventilation, reduces defective products.
Technology solution of the present utility model is as follows:
The Injection Mold that can ventilate in a kind of mould comprises master mold, and described master mold middle part forms the injection mo(u)lding groove, and master mold inside is provided with horizontal slotted hole and vertical hole, and vertical Kong Yiduan communicates with horizontal slotted hole, the other end communicates with the injection mo(u)lding groove; Laterally the inlet end of slotted hole communicates with breather pipe.
In described horizontal slotted hole and the vertical master mold of pore size distribution below the injection mo(u)lding groove.
Described master mold inside forms two horizontal slotted holes and eight vertical holes, and every horizontal slotted hole communicates with four vertical holes, and two horizontal slotted holes are parallel to each other, and every vertical hole is parallel to each other.
The beneficial effects of the utility model are: it in die sinking in a flash, enter horizontal slotted hole by ventilation in breather pipe and be blown into the injection mo(u)lding groove from vertical hole again, blow internally, make product cooling fast, thereby prevent that product and mould are due to the bonding dust that produces, shorten the formed product cycle, reduce defective products.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Main element symbol description: 1, master mold; 11, injection mo(u)lding groove; 2, horizontal slotted hole; 3, vertical hole.
The specific embodiment:
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment: see shown in Fig. 1 to 2, the Injection Mold that can ventilate in a kind of mould, comprise master mold 1, described master mold 1 middle part forms injection mo(u)lding groove 11, master mold 1 inside is provided with horizontal slotted hole 2 and vertical hole 3, and vertical hole 3 one ends communicate with horizontal slotted hole 2, the other end communicates with injection mo(u)lding groove 11; Laterally the inlet end of slotted hole 2 communicates with breather pipe, and breather pipe and air-operated solenoid valve are come round, and air-operated solenoid valve is controlled by computer.
Described horizontal slotted hole 2 and vertical hole 3 are distributed in the master mold 1 of injection mo(u)lding groove 11 belows, master mold 1 inside forms two horizontal slotted holes 2 and eight vertical holes 3, every horizontal slotted hole 2 communicates with four vertical holes 3, and two horizontal slotted holes 2 are parallel to each other, and every vertical hole 3 is parallel to each other.
Operation principle: by the time of computer setup control ventilation, when a die sinking, ventilate by breather pipe, gas is blown into horizontal slotted hole 2 enters again vertical hole 3, blow at last injection mo(u)lding groove 11, the product in injection mo(u)lding groove 11 is blown, make product cooling fast, thereby prevent product and mould due to the bonding dust that produces, shorten the formed product cycle, reduce defective products.
