A kind of north benz jackshaft cylinder gear speed reducer shell casting particular manufacturing craft, including top swage, anvil swage and core model, top swage is fastened on anvil swage, there are gaps between the two, the gap is the space of casting reducing gearbox, the anvil swage is the cavity to concave, core model and chill are placed in cavity, the top swage is that entirety projects upwards the profile to form reducing gearbox, the chill slot to lower recess and the core model slot to lower recess are equipped on top swage, core model in core model slot and anvil swage corresponds to, chill slot and chill position correspond to, cast gate is equipped at core model groove center, running channel is communicated with by cast gate.Relative to the prior art, the utility model is arranged on using gate location among core model, and the position of upper anvil swage and previous position are opposite, after cast gate is arranged on centre, molten iron is uniform toward the flowing of mold surrounding, it avoids because loose caused by molten iron flow is irregular around reducing gearbox, cooling is rapid, improves product qualification rate.

Description

North benz jackshaft cylinder gear speed reducer shell casting particular manufacturing craft

Technical field

The utility model is related to auto parts machinery manufacture fields, and in particular to north benz jackshaft cylinder gear speed reducer shell casting Make particular manufacturing craft.

Background technology

Perigene mechanical fitting Co., Ltd of Linzhou City casts all the time produces north benz jackshaft cylinder gear speed reducer During shell, cast from reducing gearbox lower floor side, if at A, molten iron flows from bottom to top in Fig. 1, due to lower floor one enclose it is larger, and Shell wall is thin, and when flowing to opposite side from gate location, cooling is rapid, causes opposite side loose, seriously affects product qualification rate.

Utility model content

For above-mentioned technical problem, it is special that the utility model provides a kind of north benz jackshaft cylinder gear speed reducer shell casting With mold, solve the problems, such as that reducing gearbox is loose.

The technical solution of the utility model is specially：

A kind of north benz jackshaft cylinder gear speed reducer shell casting particular manufacturing craft, including top swage, anvil swage and core model, Top swage is fastened on anvil swage, between the two there are gap, the gap be cast reducing gearbox space, the anvil swage Be the cavity to concave, be placed with core model and chill in cavity, core model is metal cylinder structure, the top swage be it is whole to Upper protrusion forms the profile of reducing gearbox, and the chill slot to lower recess and the core model slot to lower recess, core are equipped on top swage Core model in die cavity and anvil swage corresponds to, and chill slot and chill position correspond to, and cast gate is equipped at core model groove center, is connected by cast gate There is running channel, channel is provided with around core model slot.

Running channel there are two being opened by the cast gate, the channel sets at least five, and has beeline channel and bending channel.

Relative to the prior art, the technique effect of the utility model is to be arranged among core model come generation using gate location Side is arranged on, and the position of upper anvil swage and previous position are opposite, cast gates in the utility model for previous cast gate After being arranged on centre, molten iron is uniform toward the flowing of mold surrounding, avoids because molten iron flow is irregular around reducing gearbox, cooling is fast It is loose caused by speed, improve product qualification rate.

Fig. 3 is the schematic top plan view of the anvil swage of the utility model.

Specific embodiment

North benz jackshaft cylinder gear speed reducer shell casting particular manufacturing craft includes top swage, anvil swage and core model.Casting When top swage and anvil swage snap together, and between the two there are gap, be to slow down after the gap casting molten iron molding Device shell, it is the cavity to concave to state anvil swage, is placed with core model 1 and chill 2 in cavity, and core model 1 is metal cylinder structure, institute It is the profile of formation reducing gearbox integrally projected upwards to state top swage, and 6 He of chill slot to lower recess is equipped on top swage To the core model slot 5 of lower recess, the core model 1 in core model slot 5 and anvil swage corresponds to, and chill slot 6 and 2 position of chill correspond to, core model slot 5 Cast gate 3 is equipped at center, is opened by cast gate there are two running channel 4, is provided with channel around core model slot 5, channel sets at least five, and has Beeline channel and bending channel, allow molten iron to be flowed out from channel, flow to edge.

During casting, top swage protrusion part is fastened in the cavity of anvil swage, there are gap, the shapes in gap between the two Shape is reducing gearbox, and from pouring molten iron at cast gate 3, molten iron flows out to 1 surrounding of core model from running channel 4, then around top swage Channel is flowed around until the gap filling in upper anvil swage is finished, and from the intermediate setting cast gate of mold, molten iron flow arrives The time phase difference of surrounding is little, in the prior art will be prominent compared to cast gate is arranged on side flowing evenly before Pattern is as anvil swage, both can could also with pouring molten iron at cast gate and using the mold of protrusion as top swage in the utility model Enough easy to exhaust.

Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art For, under the premise of the utility model general idea is not departed from, several changes and improvements can also be made, these should also be considered as The scope of protection of the utility model.
