Technical field

The present invention relates to injection mold field, specifically refer to the mold stripping method of the long barrel shape goods of a kind of injection mold.

Background technology

At present, in injection mold field, for the mold stripping method of long barrel shape goods, what usually adopt technically is conventional die cavity and dynamic model, and the demoulding adopts stripper plate to be ejected by goods; But this mold stripping method exists two large shortcomings, first depth of cavity is dark, and this makes die cavity border thickness must be large, ensures that die cavity can not ftracture in long injection moulding is produced, cause material cost and processing cost higher; It two is that mold thickness is thick, and the board tonnage that mould needs is large, and production cost is higher; Thoughts on this, in view of prior art is inadequate, for the practical problem of long bucket goods depanning mode, devise the mold stripping method of the long barrel shape goods of a kind of injection mold, change upper and lower for traditional dark cavate depanning mode into lie on one's side and add and loose core mode depanning, project organization is reasonable, easy to operate, safe and reliable, and significantly can reduce manufacture and production cost.

Summary of the invention

Technical problem to be solved by this invention is the mold stripping method providing the long barrel shape goods of a kind of injection mold, reasonable in design, and working stability is safe and reliable, cost-saving; For solving above-mentioned existing technical problem, the present invention adopts following scheme: the mold stripping method of the long barrel shape goods of a kind of injection mold, comprises hydraulic cylinder 1, hydraulic cylinder fixed head, push rod, guide post, push pedal, sliding connection plate, confined planes, cover half limited block, core, product, cover half fixed head, cover half, guide pillar, dynamic mould fixing plate, dynamic model, dynamic model limited block.

As preferably, described sliding connection plate respectively with the groove fit on cover half fixed head, cover half, dynamic mould fixing plate, dynamic model 1, and can to move up and down, as shown in Figure 1, Figure 2, Figure 3 shows.

As preferably, the confined planes in described sliding connection plate contacts with dynamic model limited block with cover half limited block respectively, as shown in Figure 1 and Figure 2.

As preferably, described cover half limited block, dynamic model limited block are fixedly connected with fixed half and moving half respectively, as shown in Figure 1, Figure 3.

As preferably, the one side that described dynamic model is relative with cover half is provided with guide pillar, as shown in Figure 1.

As preferably, described core is fixed in push pedal, and coordinates with sliding connection plate, as shown in Figure 1 and Figure 2.

As preferably, in described push pedal, holes coordinates with guide post, is middlely fixedly connected with push rod, as shown in Figure 1 and Figure 2.

As preferably, described guide post is fixedly connected with hydraulic cylinder fixed head with sliding connection plate respectively, as shown in Figure 1, Figure 2, Figure 3 shows.

As preferably, described hydraulic cylinder is fixed on hydraulic cylinder fixed head, and can drive push rod side-to-side movement, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5.

Beneficial effect: the mold stripping method of the long barrel shape goods of a kind of injection mold, in the upper and lower depanning mode of traditional dark cavate, by goods half-twist, it is patrix that half is made in dark chamber originally into, and half is counterdie, and dynamic model originally makes hydraulic cylinder loosing core into, so significantly decrease mould gross thickness, mould can be produced at less board, simultaneously in the production and processing of mould, decrease a large amount of material costs and processing cost.

Detailed description of the invention

As shown in Fig. 1-3, the mold stripping method of the long barrel shape goods of a kind of injection mold, comprise hydraulic cylinder 1, hydraulic cylinder fixed head 2, push rod 4, guide post 3, push pedal 5, sliding connection plate 6, confined planes 61, cover half limited block 7, core 8, product 9, cover half fixed head 10, cover half 11, guide pillar 12, dynamic mould fixing plate 13, dynamic model 14, dynamic model limited block 15, it is characterized in that: hydraulic cylinder 1 is bolted on hydraulic cylinder fixed head 2, two guide posts 3 are each passed through push pedal 5 holes.

Described sliding connection plate 6 respectively with the groove fit on cover half fixed head 10, cover half 11, dynamic mould fixing plate 13, dynamic model 14, and can to move up and down, as shown in Figure 1, Figure 2, Figure 3 shows.

Confined planes 61 in described sliding connection plate 6 contacts with dynamic model limited block 15 with cover half limited block 7 respectively, as shown in Figure 1 and Figure 2.

Described cover half limited block 7, dynamic model limited block 15 are fixedly connected with dynamic model 14 with cover half 11 respectively, as shown in Figure 1, Figure 3.

The one side that described dynamic model 14 is relative with cover half 11 is provided with guide pillar 12, as shown in Figure 1.

Described core 8 is fixed in push pedal 5, and coordinates with sliding connection plate 6, as shown in Figure 1 and Figure 2.

In described push pedal 5, holes coordinates with guide post 3, and centre is fixedly connected with push rod 4, as shown in Figure 1 and Figure 2.

Described guide post 3 is fixedly connected with hydraulic cylinder fixed head 2 with sliding connection plate 6 respectively, as shown in Figure 1, Figure 2, Figure 3 shows.

Described hydraulic cylinder 1 is fixed on hydraulic cylinder fixed head 2, and can drive push rod 4 side-to-side movement, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5.

During real work, during injection moulding as shown in Figure 3,4, after injection operation completes, as shown in Figure 5, dynamic model 14 separates with cover half 11, and the dynamic model limited block 15 on dynamic model 14 touches confined planes 61, drive sliding connection plate 6 to follow dynamic model 14 to move, until confined planes 61 touches cover half limited block 7, stop die sinking; Hydraulic cylinder 1 pulls push rod 4, push rod 4 pulls push pedal 5, core 8 and product 9 to move right, move after a segment distance, product 9 encounters sliding connection plate 6, core 8 continues to move right, and meanwhile, product 9 is encountered the stop of sliding connection plate 6 and is in stopping and moves right, this makes product 9 depart from core 8, complete product 9 whole go out mold process.

Instant invention overcomes the problems such as the dark cavate depanning mode volume of tradition is large, cavity wall thickness degree is large, materials are many, processing cost is high; Use the depanning mode adding and loose core of lying on one's side, by goods half-twist, it is patrix that half is made in dark chamber originally into, and half is counterdie, and dynamic model originally makes hydraulic cylinder loosing core into, thus reduces the volume of mould, reduces production cost; Flexible and convenient operation in production, efficiency are high, and working stability is safe and reliable.

Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
