Description
Technical field
This utility model belongs to field of die equipment, is specifically related to a kind of injection mold.
Background technology
Refrigerator, its inside gadget of the household electrical appliances such as refrigerator-freezer typically each adopts moulding, particularly as fruit and vegetable box, drawer box, the mouldings such as ice making box, its surface quality to injecting products, the demoulding that injection moulding completes requires very strict, for box-packed moulding, it is in knockout course, when core rod extracts box-packed moulding out, vacuum can be formed between core rod and cassette bottom, if air can not be introduced at its contact surface in time, due to vacuum and atmospheric pressure reduction, core rod can be made to extract out extremely difficult, in order to solve this problem, frequently with the valve type push rod use as vacuum breaker, but its cost of pneumatic cylinder push rod is high, and it is susceptible to fault when using, have impact on the service life of injection mold.
Utility model content
The purpose of this utility model is in that to provide a kind of injection mold, realizes push rod ejection device compressing air, with the problem solving to propose in above-mentioned background technology.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of injection mold, it mainly includes cast gate, set screw, centring ring, die cavity, cover half seat, guide pillar, cover half core, cushion block, dynamic model seat, bolt, sealing ring, moving-mould-core, sprue bush and mould emptier, described mould emptier is positioned at dynamic model seat, between cushion block and moving-mould-core, described mould emptier mainly includes air cock and is positioned at the push rod of air cock surrounding, described air cock is placed on dynamic model seat, in cavity between cushion block and moving-mould-core, the top of described air cock is positioned at below die cavity, bottom is provided with sealing ring, the bottom of described air cock is bolted support.
Preferably, the surrounding valve body of described air cock is provided with the spring of buffering.
Preferably, described air cock side is communicated with the gas channel being located in cushion block.
The beneficial effects of the utility model are: its simple in construction, easy for installation, by by air cock and push rod combination, more quickly finish the demoulding of moulding, utilize the air that the gentle circulation road storage of cavity placed by air cock to realize injection moulding and complete the introducing of air between core rod and cassette bottom in knockout course, while ensureing moulding surface quality requirements, the problem effectively solving molding vacuum.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of injection mold that the utility model proposes；
Number in the figure: 1, cast gate, 2,18,22, set screw, 3, centring ring, 4, die cavity, 5, cover half seat, 6, guide pillar, 7,8,19, cushion block, 9,12,17, push rod, 10, gas channel, 11, dynamic model seat, 13, air cock, 14, spring, 15, bolt, 16, sealing ring, 20, moving-mould-core, 21, cover half core, 23, sprue bush.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, a kind of injection mold, it mainly includes cast gate 1, set screw 2, 18, 22, centring ring 3, die cavity 4, cover half seat 5, guide pillar 6, cushion block 7, 8, 19, dynamic model seat 11, bolt 15, sealing ring 16, moving-mould-core 20, cover half core 21, sprue bush 23 and mould emptier, described mould emptier is positioned at dynamic model seat, between cushion block and moving-mould-core, described mould emptier mainly includes air cock 13 and is positioned at the push rod 9 of air cock 13 surrounding, 12, 17, described air cock 13 is placed on dynamic model seat 11, cushion block 8, in cavity between 19 and moving-mould-core 20, the top of described air cock 13 is positioned at below die cavity 4, bottom is provided with sealing ring 16, the bottom of described air cock 13 supports by bolt 15 is fixing.
For further optimisation technique scheme, the surrounding valve body of described air cock 13 is provided with the spring 14 of buffering.
For further optimisation technique scheme, described air cock side is communicated with the gas channel 10 being located in cushion block.
Operation principle: utilize the air that gentle circulation road 10 storage of cavity placed by air cock 13 to realize injection moulding and complete the introducing of air between core rod and cassette bottom in knockout course, it is ensured that while moulding surface quality requirements, the problem effectively solving molding vacuum.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent replacement; all within spirit of the present utility model and principle; any amendment of being made, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
