Description
Technical Field
The utility model relates to an elevator accessory technical field, concretely relates to lift-cabin door change gear mould.
Background
Elevator trade door change gear is one of accessory commonly used, the door change gear is mainly made by change gear body and polyurethane tire bead, among the prior art, the main production technology of change gear body is the pouring process, the mould is made with the steel material class usually, the mould volume is great, it is improper to design at mould design in-process runner position, generally all set up 1 to 2 runners at the excircle, lead to the change gear body wall thickness inequality in the forming process easily, reduce the holistic intensity hardness of change gear, and there is the air in the pouring process, if can not in time get rid of the air, remain in the change gear originally internally, easily lead to change gear body internal stress concentration and produce the crackle, influence the change gear use, the safety of while serious influence elevator.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, provide an elevator door change gear mould, the runner position is reasonable, sets up the air discharge duct, avoids stress concentration, improves change gear body production quality.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an elevator door change gear mould, includes mould and lower mould, it respectively is equipped with one end open-ended one-tenth die cavity, its characterized in that to go up mould and lower mould middle part: go up mould shaping chamber terminal surface and be equipped with the muscle groove that can be used to the shaping strengthening rib, go up the mould middle part and wear to be equipped with the main runner, the main runner leads to have a plurality of groups and the main subchannel that switches on, the subchannel extends to change wheel hub side middle part, the lower mould middle part is equipped with the columnar body that can be used to shaping change gear body middle part cavity, lower mould shaping chamber terminal surface is equipped with the corresponding muscle groove in mould shaping chamber with last.
By adopting the technical scheme, because the wheel hub of the change gear body in the change gear of the elevator door is the main stressed position, the forming of the wheel hub part directly influences the use performance of the change gear of the elevator door in the whole casting process of the change gear body, and the utility model discloses a through setting the runner in the middle part of the side surface of the change gear wheel hub, firstly, the wheel hub part is fully filled with the melting casting material, the wall thickness of the wheel hub part is ensured to be uniform, stress concentration is avoided, secondly, the machining precision requirement of the side surface of the change gear body is not high, the change gear body can not be influenced by the residual waste material formed by the runner after the forming, secondary machining is not needed, and the whole; the rib grooves are formed in the end faces of the upper die forming cavity and the lower die forming cavity and used for forming the reinforcing ribs on the two side faces of the change gear body, so that the deformation resistance of the change gear body is improved, and the service life of the change gear body is prolonged.
The elevator door change gear mould can be further set as follows: the lower die is uniformly distributed with a plurality of groups of first exhaust holes at the position of the rib groove.
Adopt above-mentioned technical scheme, the one of which, because the change gear body is at the casting forming in-process, the molten material gets into the shaping intracavity and carries out the casting forming, can remain waste gas, if these waste gases do not get rid of, it is originally internal to be stayed at the change gear, can lead to the inside stress concentration of change gear body to produce the crackle, seriously influence the performance of change gear body, through addding the exhaust hole, can collect remaining waste gas, avoid waste gas to remain at the change gear originally internally, its two, because the strengthening rib is the intensity that is used for strengthening the change gear body, the surface machining precision requirement is lower, so add the exhaust hole in the muscle inslot, after the exhaust groove takes out, remaining waste material can not influence the strengthening rib, need not carry out secondary operation, reduce change gear body whole processing.
The elevator door change gear mould can be further set as follows: and a second exhaust groove is annularly formed on the periphery of the lower die, which is positioned on the hub of the forming change gear.
Adopt above-mentioned technical scheme, the purpose of addding the second air discharge duct is for getting rid of the unnecessary waste gas of wheel hub border position, the follow-up procedure such as numerical control processing that need carry on in change gear body wheel hub position is the form of slot with wheel hub position processing, so that installation polyurethane tire bead carries out pressure roll with the track, so the intensity requirement of wheel hub slot both sides is higher, through addding the second air discharge duct, collect unnecessary waste gas to change gear wheel hub periphery, it remains originally internally to avoid waste gas, further strengthen the intensity of change gear body, promote change gear production quality.
The elevator door change gear mould can be further set as follows: one end of the cylindrical body, which is close to the upper die, is provided with a protruding cylindrical table, and the branch channel is positioned on the end surface of the cylindrical table.
By adopting the technical scheme, the inner periphery of the roller table is used for forming the gear body and is used for limiting the position blocking block of the rolling bearing, the subsequent processing procedures of the gear body can be reduced, the production cost of the gear body is reduced, and the production period of the gear body is shortened.
The elevator door change gear mould can be further set as follows: and the upper die and the lower die are respectively provided with a weight avoiding groove relative to the outer end surface of the forming cavity.
By adopting the technical scheme, the die is made of steel materials, and the overall weight of the die can be reduced by additionally arranging the weight avoiding grooves on the outer parts of the upper die and the lower die.
The utility model has the advantages that: the elevator door change gear mould is provided, the position of the gate is reasonable, the exhaust groove is arranged, the stress concentration is avoided, and the production quality of the change gear body is improved; the sprue is arranged in the middle of the side face of the change gear hub, so that firstly, the hub part is fully filled with molten pouring materials, the uniform wall thickness of the hub part is ensured, stress concentration is avoided, secondly, the machining precision requirement on the side face of the change gear body is not high, the change gear body is not influenced by residual waste materials formed by the sprue after molding, secondary machining is not needed, and the whole machining process of the change gear body is reduced; the rib grooves are formed in the end faces of the upper die forming cavity and the lower die forming cavity and used for forming reinforcing ribs on two side faces of the change gear body, so that the deformation resistance of the change gear body is improved, and the service life of the change gear body is prolonged; a plurality of groups of first exhaust holes are uniformly distributed at the positions of the rib grooves of the lower die, and second exhaust grooves are annularly arranged on the periphery of the hub of the forming change gear of the lower die, so that residual waste gas is collected, the waste gas is prevented from remaining in the change gear body, the strength of the change gear body is further enhanced, the production quality of the change gear is improved, the uniform wall thickness of each part of the change gear body is ensured, and stress concentration is avoided; the whole weight of the die can be reduced by additionally arranging the weight avoiding grooves outside the upper die and the lower die.
