Description

Insulating bushing pressing die

Technical field

The utility model relates to mould applications, is specifically related to a kind of insulating bushing pressing die.

Background technology

Press-moulding die is called for short pressing mold.Directly added in unlimited mold cavity by plastic raw materials, then closed by mould, plastics become flow regime and are full of die cavity under heat with the effect of pressure; Then because physical change makes plastic hardening shape, this method is just named compressing, and mould used is called press-moulding die.This mould is used for greatly the processing and forming of thermosetting plastics, also has for thermoplastic.The cold moudling compacting tool set do not heated in addition in addition, for shaping polytetrafluoroethylene (PTFE) blank.

In recent years, along with the develop rapidly of plastics industry and general, engineering plastics improving constantly in intensity and precision etc., make the range of application of plastic products also in continuous expansion, as various fields such as household electrical appliance, instrument and meter, construction equipment, auto industry, haberdashery and hardware, the ratio shared by plastic products just rapidly increases.Wherein, village is enclosed within valve field and uses extensively, village's cover be liner effect change cover.In valve applications field, lining is used within valve gap, generally uses the anticorrosive materials such as melamino-formaldehyde, polytetrafluoroethylene (PTFE) or graphite, for sealing function.In moving component, the wearing and tearing of part are caused because of long-term friction, must renewal part when the gap in axle and hole may wear to a certain degree time, therefore when design, designer selects that hardness is lower, the good material of wearability is axle sleeve or lining, the wearing and tearing of axle and seat can be reduced like this, when axle sleeve or liner wear are changed to a certain extent, the cost because changing axle or seat can be saved like this.

Along with growing to plastic cement products demand of people, the output of mold is had higher requirement, therefore, the mould of the lining just need produced is overlapped in a large amount of replacing villages, and existing mould structure is complicated, and once compressing one, its production efficiency is low, causes the raising of production cost.

Utility model content

The utility model is intended to provide the insulating bushing pressing die that a kind of structure is simple, production efficiency is high, production cost is low.

For achieving the above object, base case of the present utility model is: insulating bushing pressing die, comprises detent mechanism, lower detent mechanism and clamping device, and described clamping device is arranged between detent mechanism and lower detent mechanism; Described upper detent mechanism comprises cope match-plate pattern and upper mounted plate, and described cope match-plate pattern is fixedly connected with upper mounted plate, is provided with punch and upper guide post in fixed plate; Described lower detent mechanism comprises lower bolster and bottom plate, and described lower bolster is fixedly connected with bottom plate, is provided with lower guide pillar and multiple core in described bottom plate; Described clamping device comprises hollow die sleeve and die, and described die sleeve is socketed on die, is provided with locating hole in described die sleeve; Described upper guide post and lower guide pillar are separately positioned on the two ends of locating hole, and described punch is relative with die, and described core interts in die, and described punch, die and core surround forming cavity.

The principle of base case: during operation, is first fixedly connected with lower bolster with bottom plate, and die sleeve is socketed on die, and die sleeve is fixedly connected with bottom plate with lower guide pillar by multiple core, surrounds loading chamber by die and core; Then directly added in loading chamber by plastic raw materials, force promotion cope match-plate pattern orders about punch and moves to die, and upper guide post downward guide pillar in locating hole moves simultaneously, and when punch and die offset, punch, die and core surround forming cavity; Last plastics are flow regime and are full of the forming cavity of concavity under heat with the effect of pressure, and by physical change, plastic hardening is shaped, after compressing, take out die sleeve from pressing mold, being placed in special unloading on mould bases carries out inloading part, obtains plastic.

The advantage of base case: surround forming cavity mainly through punch, die and core, plastics are flow regime and are full of the forming cavity of concavity under heat with the effect of pressure, and by physical change, plastic hardening is shaped, its overall structure is simple; Because core is multiple, therefore once compressing plastic is more than one piece, effectively raises production efficiency, reduces production cost.

Preferred version one, based on the preferred version of scheme, the quantity of described core is set to four, and by above-mentioned setting, when core is four, once compressing plastic is four, effectively enhances productivity; When core is less than four, production efficiency reduces, and causes the raising of production cost; When core is greater than four, in compressing process, job stability is poor, finally obtains plastic quality lower.

Preferred version two, based on the another preferred version of scheme, be provided with backing plate between described die sleeve and bottom plate, by above-mentioned setting, in pressing process mistake, backing plate effectively decreases the abrasion condition of die sleeve and bottom plate, improves the service life of die sleeve and bottom plate.

Preferred version three, based on the another preferred version of scheme, the both sides of described die sleeve are equipped with handle, by above-mentioned setting, after compressing, take out die sleeve by handle, have more feel, more laborsaving.

Preferred version four, based on the another preferred version of scheme, described cope match-plate pattern and lower bolster are equipped with limit screw, by above-mentioned setting, when compressing, limit screw limits cope match-plate pattern and lower bolster movement in the horizontal direction, and compressing rear for convenience detach.
