Description
Technical field
The utility model relates to mold machining technology fields, pull pin hammer more specifically, being related to one kind.
Background technique
A set of casting mould is by components structures such as upper plunger tip plate, air blowing plate, sand ejection board, upper core box, lower core box, lower plunger tip plates
At being wherein equipped with positioning pin in upper core box, set pin sleeve be housed in lower core box, play positioning in the process in mold movement (molding)
Effect, because mold movement number is more, positioning pin and set pin sleeve are all comparatively fast worn, to guarantee the accuracy positioned, therefore
It is frequently necessary to replace both parts, since the assembly of positioning pin, set pin sleeve and upper and lower core box is all using interference fit, institute
Core box need to be removed when replacing from equipment, then remove plunger tip plate, air blowing plate, sand ejection board, lower plunger tip plate one by one in turn
Upper core box, lower core box are hung out, the extraction such as Song Zaiyong glue pincers, spanner is then first struck to positioning pin, another side overturns lower core box,
It borrows the tools such as chisel, iron hammer and set pin sleeve is got by set pin sleeve mounting hole from the back side, set pin sleeve mounting hole needs here
It passes to and is conducive to get guide from the back side, and because lower core box is linked together with lower plunger tip plate, changeing set pin sleeve
When, it needs first to split out lower plunger tip plate, to be replaced finish is reinstalled again, due to the lower plunger tip bar and lower core box on lower plunger tip plate
Fit clearance it is very small, dismount back and forth it is more troublesome, at least cost time half a day, meanwhile, in order to which set pin sleeve is got
Mounting hole need to be punched when core box is processed, be also a kind of challenge to processing when core box thickness is a the larger value.
Simultaneously because positioning pin, set pin sleeve are all to put into upper and lower core box by interference fit, when replacement, is more bothersome,
Positioning pin first can only hammer pine into shape with hammer, then little by little be eased out with glue pincers or spanner, and the gruelling and cost time is many, when serious
It can also do and hurt mold, therefore, pull pin hammer it is urgent to provide a kind of new combined type.
Utility model content

By setting link block A and link block B in the device, by by link block A attachment screw A, link block B attachment screw B, thus
The advantages that having reduction mold difficulty of processing, improve bench work efficiency, easing off the pressure to product delivery.
To achieve the above object, the utility model provides the following technical solutions: a kind of combined type is pulled pin hammer, including connecting rod and
Sleeve, the connecting rod top are provided through sleeve, and described connecting rod one end has been connected through a screw thread link block A, the link block A
Screw A is provided with by screw thread insertion far from connecting rod one end.
Further preferred embodiment: the threaded one end opening inside diameter that the link block A is connected with screw A is M12, and spiral shell
The diameter of thread on nail A matches with link block A.
Further preferred embodiment: the both ends the screw A are equipped with screw thread.
Further preferred embodiment: being in mating setting between the connecting rod, sleeve, link block A and screw A.
Meanwhile the utility model provides the following technical solutions: a kind of combined type is pulled pin hammer, including connecting rod and sleeve, described
It is provided through sleeve above connecting rod, described connecting rod one end has been connected through a screw thread link block B, and the link block B other end is embedding
Enter to be provided with screw B.
Further preferred embodiment: the link block B internal whorl is integrally in penetration type setting, and spiral shell inside link block B
Pit diameter is M24.
Further preferred embodiment: the screw B diameter model is M24, and the cutting of the one end screw B is equipped with bevel edge, simultaneously
Screw B bevel edge end and set pin sleeve pass through 90 ° of fixations of rotation.
Further preferred embodiment: being in mating setting between the connecting rod, sleeve, link block B and screw B.
The utility model has the advantages that
1, this kind of combined type is pulled pin hammer, and structure is simple, and connecting rod, sleeve, link block A, screw A, link block B and screw B are equal
It can be got by lathe process, and required precision is low, while standard component, the screw B of M24 model can be used in the M12 screw A of model
Head of screw trimming processing is relatively easy to, and entire component assembly is flexibly simple, economical and practical.
2, it is pulled pin hammer by this kind of combined type, positioning pin replacement is more convenient, and lower core box is without splitting out lower plunger tip plate i.e.
Set pin sleeve can be got from the back side, the inconvenience for dismounting lower plunger tip bar is omitted, so that pincers worker demoulding is convenient significantly, improve work
Make efficiency.
3, core box difficulty of processing is reduced, after having the hammer of pulling pin, the set pin sleeve mounting hole in lower core box is not necessarily to run through,
To be more advantageous to the biggish processing of core box thickness value.
To sum up, this kind of combined type hammer of pulling pin has wide applicability, mentioned above in the background art existing to solve
Mold changes the problem of positioning pin hardly possible, to have reduction mold difficulty of processing, improve bench work efficiency, delivers to product
The advantages that easing off the pressure.
