The invention discloses a mold locking device, which comprises a frame body, a mold and a carrying part, wherein the carrying part is used for carrying the mold, the frame body comprises an accommodating space, an opening parallel to a mold opening direction is arranged on the accommodating space, and a mold locking slope part is arranged on the horizontal inner wall of the accommodating space, one side of the mold corresponding to the mold locking slope part is also provided with a matched mold slope part, and the mold enters the accommodating space along a slope. When the mold is completely placed into the accommodating space, the accommodating space and the mold have the same cross section outline in the parallel mold opening direction in the cross section in the parallel mold opening direction.
Description
Technical field
The invention relates to a kind of clamping apparatus, but particularly relevant for a kind of clamping apparatus of tight closure mould.
Background technology
Clamp force is meant that mould from being closed into the material feeding moulding until the process of opening once more, keeps the strength of mould closes.It is to judge required clamp force tonnage according to product size and plastic properties, is one of mould board important indicator when selecting for use.At present, clamping mechanism roughly can divide crank-type, direct press type, three kinds of clamping mechanisms of compound direct press type.Crank-type is to drive crank start running by clamping cylinder or fluid cylinder; Direct press type is to utilize hydraulic cylinder or cylinder directly as the pressure source of compacting tool set; Compound direct press type is identical with direct press type; But compound direct press type is adopted little hydraulic pressure or vapour pressure cylinder in long distance motion, when the high pressure mold closing, adopts big hydraulic pressure of short stroke or vapour pressure cylinder, more compound direct press type economy.
But, the still clamping mechanism of the most widely using at present of crank-type is because it is simple to operate, operating cost is minimum and the switch mould is fastest.But the partial structure of this kind clamping mechanism locked mode is complicated, and because of to the stress point of mould in the outside, so deflection is bigger, must the consideration depth of parallelism and abrasion problem, to influencing also bigger die life.At the normal lubricating maintenance of noting crank connecting link and axle center of maintenance part palpus, the cleanliness factor aspect, little as adopting the self-lubricating bearing person to pollute, no self-lubricating bearing person then pollutes greatly.
Summary of the invention
Because above-mentioned prior art problems; One of the object of the invention is providing a kind of clamping apparatus exactly; Structure is more succinct to provide, operation is quicker, and clamp force is evenly distributed to mould, does not influence the also more cheap clamping apparatus of while cost die life.
According to the object of the invention, a kind of clamping apparatus is proposed, it comprises framework and mould.Framework comprises accommodation space, and in order to pin mould, it has the opening of parallel die sinking direction.The one side of the level of accommodation space inwall is provided with the locked mode ramp, and mould is provided with the mould ramp with respect to the position of this locked mode ramp.After the mould closes, cooperate locked mode ramp and mould ramp, make mould get into accommodation space via opening.When mould appears when being locked state, in the section of parallel die sinking direction, accommodation space is consistent with the profiled outline of closed its parallel die sinking direction of mould.So, can reach easily mould closes in framework, and clamp force is evenly distributed to mould, not influence the also purpose of more cheap clamping apparatus of while die life cost.
Wherein, clamping apparatus more comprises supporting part, and it connects the one side extension of accommodation space inwall near the level on ground, in order to carry the mould of closure or unlatching.
Wherein, the locked mode ramp is set at the one side of accommodation space inwall away from the level on ground, and the one side of supporting part carrying mould is the extension of level.
Wherein, the locked mode ramp is set at the one side of accommodation space inwall near the level on ground, and the one side that supporting part carries mould appears and the extension of locked mode ramp with gradient.
Wherein, mould comprises first die cavity and second die cavity.First die cavity comprises and is arranged at the first heat conduction diaphragm that is lower than the first die face place, and it seals first die cavity and forms the first seal-off pressure chamber.The first heat conduction diaphragm is provided with first template back to a side in seal-off pressure chamber, and the another side of first template is the first stamping face.At least one first liquid gateway is arranged at around first die cavity, and communicates with the first seal-off pressure chamber.Second die cavity comprises and is arranged at the second heat conduction diaphragm that is lower than the second die face place, and it seals second die cavity and forms the second seal-off pressure chamber.The second heat conduction diaphragm is provided with second template back to a side in the second seal-off pressure chamber, and the another side of second template is the second stamping face.At least one second liquid gateway is arranged at around second die cavity, and communicates with the second seal-off pressure chamber.
Wherein, when first die cavity and second cavity closed, confined space comes across between the first stamping face and the second stamping face, and confined space is in order to place the impression thing.
Wherein, when the mould ramp was set at the first die cavity outer rim back to the one side of first die face, the locked mode ramp then was arranged on next-door neighbour's opening and away from the horizontal plane on ground.
Wherein, when the mould ramp was set at the second die cavity outer rim back to the one side of first die face, the locked mode ramp then was arranged on next-door neighbour's opening and subaerial horizontal plane.
Hold the above, according to clamping apparatus of the present invention, it can have one or more following advantages:
(1) this clamping apparatus has succinct structure, can make operation quicker, has advantage cheaply simultaneously.
(2) this clamping apparatus can evenly make clamp force be distributed on the mould, can solve the problem that reduces because of the clamp force skewness die life by this.
