This kind of simple structure, with low costs, production efficiency is high.
Description
Technical field
The utility model relates in a kind of injection mold injection moulding avoids orifice edge to occur weld bond, that is, avoids orifice edge to occur the new construction of weld bond for injection mold provides in a kind of effective solution injection moulding.
Background technology
In today of mould industry fast development, product surface quality requires also more and more higher.In injection mold, due to stream, the annex in hole there will be unavoidable weld bond, pressure line, and by the adjustment of mold temperature, weld bond can improve; But very high product is required for product surface, partial bores can only be cancelled injection moulding, after injection moulding completes, then carry out post processing.Some Foreign Users often require to open one pair of diel in addition, are specifically designed to punching process, which increase a procedure, simultaneously the corresponding requirement that can produce the factors such as artificial, time, equipment, transport, storage.Therefore, need effectively to solve in injection moulding to avoid orifice edge to occur the problem of weld bond.
Summary of the invention
For solving the problem, the utility model proposes a kind of technical scheme, that is: a kind of structure of automatic punching in injection moulding process, comprise order hot runner part and cut hole part, described order hot runner part comprises hot mouth (1), product (2), needle oil cylinder (3), flow distribution plate (4), magnetic valve (5) etc., described cut hole part comprises punch (7), male mold inserts (8), punching slide block (9), punching sliding dowel block (10), the slide block back side is tiltedly carved (11), male mold inserts (12), punching slide block commutation guide rail (13), limited block (14), oil cylinder connecting block (15), punching oil cylinder (16), punching oil cylinder (16) and oil cylinder connecting block (15) are with being threaded, T-shaped connector and the punching slide block of oil cylinder connecting block (15) guide rail (13) that commutates is connected, and the T connector that the T-slot of punching slide block commutation guide rail (13) is tiltedly carved with the slide block back side bottom (11) is connected, punching sliding dowel block (10) is tiltedly carved (11) with screw with the slide block back side and is connected, with fixing punching slide block (9), male mold inserts (12) covers on male mold inserts (8), then is screwed in punch (7), and limited block (14) is directly fixed on male mold inserts (12).Such a configuration reduce the operation of punching, and required place, personnel, equipment, time, storage, transport etc., improve efficiency, provide cost savings.
Accompanying drawing explanation
Accompanying drawing 1 is the injection mold injection three-dimensional structure chart of embodiment of the present utility model.
Accompanying drawing 2 is the structure sectional view of embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is further described.
As a kind of embodiment, its technical scheme is: a kind of structure of automatic punching in injection moulding process, comprise order hot runner part and cut hole part, described order hot runner part comprises hot mouth 1, product 2, flow distribution plate 4, needle oil cylinder 3, magnetic valve 5, described cut hole part comprises punch 7, male mold inserts 8, punching slide block 9, punching sliding dowel block 10, the slide block back side tiltedly carve 11, male mold inserts 12, the commutation of punching slide block guide rail 13, limited block 14, oil cylinder connecting block 15, punching oil cylinder 16; Punching oil cylinder 16 and oil cylinder connecting block 15 are with being threaded, and T-shaped connector and the punching slide block of oil cylinder connecting block 15 guide rail 13 that commutates is connected, and the T-slot of punching slide block commutation guide rail 13 is connected with the T connector that the slide block back side is tiltedly carved bottom 11; Punching sliding dowel block 10 is tiltedly carved 11 with screw and the slide block back side and is connected, with fixing punching slide block 9; Male mold inserts 12 covers on male mold inserts 8, then is screwed in punch 7, and limited block 14 is directly fixed on male mold inserts 12.
Its operation principle and process are: magnetic valve 5 controls needle-valve oil cylinder 3 and punching oil cylinder 16, before injection moulding, the piston rod of punching oil cylinder 16 is retracted, oil cylinder connecting block 15 and punching slide block commutation guide rail 13 is driven to move to limited block 14 position, the slide block back side tiltedly carves 11, punching sliding dowel block 10, punching slide block 9 be due to the T-shaped effect that commutates, downward retraction, punching slide block 9 flushes with male mold inserts 8.During injection moulding, needle-valve oil cylinder 3 action of the hot mouth 1 of solenoid control, from the charging of hot mouth 1, hole site crossed by stream, do not form hole characteristic, first hole filled up; Solenoid control punching oil cylinder 16 piston rod stretches out, oil cylinder connecting block 15 and punching slide block commutation guide rail 13 is driven to move, the slide block back side tiltedly carves 11, punching sliding dowel block 10, punching slide block 9 be due to the T-shaped effect that commutates, move upward, punching slide block 9 stretches out punch, now, material or molten condition, punching completes; Solenoid control opens other cast gates one by one, has continued the injection moulding in other regions, and after injection moulding completes, product 2 ejects, and whole action is convenient.
This structure adds a punch mechanism at mould inside, and multiple working procedure once completes, and decreases the operation of punching, decreases place, personnel, equipment, time, storage, transport etc. that this procedure needs, improves efficiency, provide cost savings.
