Description

A kind of injection mold automatic ejection comes off the device of goods

Technical field

The invention belongs to mechanical manufacturing field, relate to a kind of injection mold automatic ejection and to come off the device of goods.

Background technology

In current Injection Industry, although part has adopted manipulator to take away goods, but relative cost is higher, injection cycle is long, some product non-appearance part, can be undertaken by Automatic-falling mode, certain problem is there is under the mode of self falling, speed is slow, come off and have some setbacks, often the manual pickup of workman is needed, increase labour intensity, this automatic ejection that just need design a kind of injection mold comes off the mechanism of goods, can solve goods falling speed slow, come off the problem had some setbacks, the automatic ejection goods mechanism that comes off of design is simple, falling speed is fast, shorten injection cycle, enhance productivity.

Summary of the invention

The object of this invention is to provide a kind of injection mold automatic ejection to come off the device of goods, as shown in Figure 1, box-like plastic products inject produce time, after push rod ejects goods, goods still stick on push rod, even if push rod is pulled, goods are taken back on the dynamic model of protrusion by by push rod again, and product cannot Automatic-falling, production department is smooth and easy, adopt this core-pulling device, can fast goods be ejected from push rod and dynamic model, and the object of Automatic-falling.

The come off device of goods of this injection mold automatic ejection is characterized in that, taken off bar, lever, top board fixed head, top board etc. formed at above-mentioned existing technology Problems existing with not enough by dynamic model, push rod, lever collision block, limited post, lever fixed block, cover half, top, design tiltedly this device utilizes lever principle to accelerate to eject goods, goods are come off from push rod and dynamic model fast, thus reaches automatic ejection and to come off the object of goods.

The invention has the beneficial effects as follows, equipment investment is few, mould structure is simple, eject apart from little, with short production cycle, simple to operate, production cost is lower, and reliability is high, is easy to standardized and popularized.

Detailed description of the invention

Be below embodiments of the invention, reality of the present invention uses and is not limited to embodiment.

Consult Fig. 1, Fig. 2, Fig. 3, in the present embodiment, the come off device of goods of a kind of injection mold automatic ejection is made up of dynamic model (2), push rod (3), lever collision block (4), limited post (5), lever fixed block (6), cover half (7), top de-bar (8), lever (9), top board fixed head (10), top board (11) etc., and wherein 1 in Fig. 1 is plastic products.Larger ejecting force is needed when goods eject, lever (9) rotates around lever fixed block under the effect of lever collision block (4), de-for top bar is accelerated to eject motion, the huge ejecting force of goods moment not easily born by the de-bar in top, owing to pushing up de-bar excessive velocities, eject to push up simultaneously and hinder goods, therefore lever collision block (4) cushions with the reserved 2mm spacing of lever (9).Lever (9) is fixed on top board fixed head (10) by lever fixed block (6), lever (9) contacts with the de-bar (8) in top and does not connect, limited post (5) is fixed on top board fixed head (10), and distance moving platen is only 10mm, namely this liftout attachment ejection stroke is only 10mm, substantially reduce ejection cycle, de-bar (8) the end face half design in top is on goods, and second half contacts with cover half.After when mould die sinking, top board (11) and top board fixed head (10) eject action under the promotion of injection machine, in the 2mm process ejected at first, push rod (3) ejects action to goods, goods are thrown off from dynamic model, when mould continues to eject, under the shock of lever collision block (4), lever (9) rotates around lever fixed block (6), de-for promotion top bar (8) is ejected product motions do acceleration by lever (9), the ejection stroke of the de-bar (8) in top will reach 60mm, and there is speed faster goods are ejected from push rod (3) and dynamic model (2), goods by Automatic-falling on conveyer belt.Top board (11) and top board fixed head (10) carry out fallback action under the effect of injection machine.Under the Action of Gravity Field of lever (9), there is certain thrust ejecting on direction, make top take off bar (8) and still keep original position, goods can not be taken back when ensureing push rod (3) rollback, reach Automatic-falling, during mould matched moulds, cover half (7) is by de-for shock top bar (8), make top take off bar (8) and lever (9) return to primitive age position, mould carries out the next injection cycle cycle.

Claims (3)

1. the automatic ejection of an injection mold comes off the device of goods, phase is characterised in that: by dynamic model (2), push rod (3), lever collision block (4), limited post (5), lever fixed block (6), cover half (7), the de-bar (8) in top, lever (9), top board fixed head (10), the compositions such as top board (11), (1) wherein in Fig. 1 is goods, bar bar fixed block (6) is fixed on top board fixed head, regulations and parameters is fixed on regulations and parameters fixed block (7) by alignment pin, and can rotate around lever fixed block (7), when top board fixed head (10) ejects together with top board, regulations and parameters collision block (4) is by knocking-on regulations and parameters (9), thus the de-bar (8) in promotion top ejects motion, owing to being regulations and parameters principle, as Fig. 1, the distance of the de-bar motion in top is 6 times that eject, therefore goods will be gone out dynamic model for top takes off masthead fast, thus realize Automatic-falling article device.

2. the automatic ejection of a kind of injection mold according to claims 1 comes off article device, it is characterized in that described goods are that one end is high, the low box in one end, leading to the de-bar (8) of the push rod (3) withstanding on mould in high one end ejects when also not returning fast, goods are not rested on push rod (3) and dynamic model (2), thus goods Automatic-falling is on conveyer belt.

3. the automatic ejection of a kind of injection mold according to claims 1 comes off article device, it is characterized in that described regulations and parameters collision block (4) and bar bar have the gap of 2mm before ejecting, avoid knock-pin and regulations and parameters to eject moment stressed excessive, reduce the fatigue strength of longtime running.
