Description

The molding ejecting mechanism of plastic bottle closure machine

Technical field

Plastic bottle closure machine is the utility model is related to, more particularly to the molding ejecting mechanism of plastic bottle closure machine.

Background technology

Equipment for manufacturing the bottle caps such as mineral water bottle and oil bottle, includes extruding machine, moulding press in forming process, cuts ring Machine and folding brake etc., extruded stock is sent in the mould of moulding press by the plastics extruded by extruding machine through scraping mechanism, through being molded into The bottle cap of type is deviate from through mould emptier from upper mold.The inside that existing moulding press is included in upper mold core sets mandril, mandril it is upper End installation roller, sets cam, roller is in rolling contact with cam, which has the drawback that on turntable：First, in upper mold core Mandril is installed, the inner space of upper mold core is taken, so that the cooling water channel of upper mold can be interfered with, mold manufacturing is had difficulties, Influence cooling effect；2nd, bottle cap is directly ejected using cam, has damage to closure inside screw thread, and take off only by cam Mould, still suffer from sometimes bottle cap it is not completely out or not in time abjection situations such as, influence next molding, mould even influenced when serious Service life；3rd, to mandril without the device being oriented to, easily there is deviation in mandril ejection, reply action, when causing the bottle cap to eject There is burr, slitter edge etc..

The content of the invention

The purpose of this utility model is to overcome prior art there are the shortcomings that, there is provided one kind ensure bottle cap completely, it is fast Speed is deviate from from mould, and the molding ejecting mechanism of accurate plastic bottle closure machine is oriented to knockout pin.

The technical solution of the molding ejecting mechanism of the utility model plastic bottle closure machine is：Including Upper Die-sleeve and die holder, on Upper core bar is set in die sleeve, lower core bar is connected under upper core bar, has cooling water channel in upper and lower core bar, upper die head is cased with outside lower core bar, Stripper sleeve is cased with outside upper die head, spring is set between stripper sleeve and upper die head, lower die head is set in die holder, it is characterised in that： The outer wall of the stripper sleeve is cased with connector sleeve, and connector sleeve connects connection ring, and connecting hole, the connecting hole connection demoulding are provided with connection ring Bar, the upper end of knockout pin set roller, guide plate are set in the template of moulding press, the guide plate, which is formed with, slips into inclined-plane and cunning Go out inclined-plane, slipping into inclined-plane and skidding off between inclined-plane has arc surface, and guide plate is oriented to roller and contacts.

The utility model discloses a kind of molding ejecting mechanism of plastic bottle closure machine, by being arranged company in the outer wall of stripper sleeve Female connector, connector sleeve connect knockout pin through connection ring, and the upper end connection roller of knockout pin, is set downwards in the template of moulding press Guide plate, guide plate are in contact with roller, and during work, Upper Die-sleeve and die holder synchronous rotary are driven by moulding press, is melted when heat Sizing material is admitted in lower die head, and lower die head is molded with upper die head, and molding obtains molding bottle cap, and bottle cap stays in upper die head at this time Outer wall, when roller rotate to when slipping into inclined-plane and being in contact, make with guide plate roller along diagonally downward slip into inclined-plane by Gradually move down, roller drives knockout pin to move down, and knockout pin drives stripper sleeve to move down through connector sleeve, and upper die head is then Remain stationary as, bottle cap is pushed down on abjection upper die head by stripper sleeve, completes the demoulding；When roller after arc surface with tilting upward When skidding off inclined-plane and being in contact, under the action of spring-return power, roller is also gradually moved up along skidding off inclined-plane, spring by Stripper sleeve homing is gradually driven, homing action is gentle, avoids stripper sleeve and upper die head from colliding and influence service life.This The molding ejecting mechanism of scheme plastic bottle closure machine, by the way that stripper sleeve is connected knockout pin through connector sleeve, then is connected by knockout pin and rolled Wheel, with roller and guide plate, realizes demoulding ejection, simple in structure, is not take up the inner space of upper and lower core bar, and ensure Bottle cap is complete, quickly deviates from from mould, and the demoulding is light.

The molding ejecting mechanism of the utility model plastic bottle closure machine, sets between the Upper Die-sleeve and knockout pin and is oriented to Set.There is guide sleeve, guiding role is played in the up and down action to knockout pin, ensures that its action is accurate, does not produce demoulding deviation.

Brief description of the drawings

Fig. 1 is the structure diagram of the molding ejecting mechanism of the utility model plastic bottle closure machine.

Embodiment

A kind of molding ejecting mechanism of plastic bottle closure machine is the utility model is related to, as shown in Figure 1, including Upper Die-sleeve 1 with Die holder 2, upper core bar 3 is set in Upper Die-sleeve, and lower core bar 4 is connected under upper core bar, has cooling water channel 20, lower core bar in upper and lower core bar It is outer to be cased with upper die head 5, stripper sleeve 6 is cased with outside upper die head, spring 7 is set between stripper sleeve and upper die head 5, is set in die holder 2 Lower die head 8, it is characterised in that：The outer wall of the stripper sleeve 6 is cased with connector sleeve 9, and connector sleeve connects connection ring 10, opened in connection ring There are connecting hole 11, connecting hole connection knockout pin 12, the upper end of knockout pin sets roller 13, sets and be oriented in the template of moulding press Plate 14, the guide plate, which is formed with to slip into, inclined-plane 15 and skids off inclined-plane 16, and slipping into inclined-plane and skidding off between inclined-plane has arc surface 17, leads It is oriented to and contacts with roller to plate.By being arranged connector sleeve 9 in the outer wall of stripper sleeve 6, connector sleeve connects knockout pin through connection ring 10 12, the upper end connection roller 13 of knockout pin, sets downward guide plate 14, guide plate connects with roller in the template of moulding press Touch, during work, 2 synchronous rotary of Upper Die-sleeve 1 and die holder is driven by moulding press, when the sizing material that heat is melted is admitted in lower die head 8, under Die head is molded with upper die head 5, and molding obtains molding bottle cap, and bottle cap stays in the outer wall of upper die head at this time, when roller 13 rotates When slipping into inclined-plane 15 and being in contact, roller 13 is set to be moved gradually downward along the inclined-plane that slips into diagonally downward to guide plate 14, Roller drives knockout pin 12 to move down, and knockout pin drives stripper sleeve 6 to move down through connector sleeve 9, and upper die head 5 is then kept not Dynamic, bottle cap is pushed down on abjection upper die head by stripper sleeve, completes the demoulding；When roller 13 after the arc surface 17 with tilting upward When skidding off inclined-plane 16 and being in contact, under the action of 7 restoring force of spring, roller 13 is also gradually moved up along skidding off inclined-plane 16, Spring gradually drives 6 homing of stripper sleeve, and homing action is gentle, avoids stripper sleeve and upper die head 5 from colliding and influence to make Use the service life.The molding ejecting mechanism of this programme plastic bottle closure machine, by the way that stripper sleeve 6 connected knockout pin 12 through connector sleeve 9, then by Knockout pin connects roller 13, with roller and guide plate 14, realizes demoulding ejection, simple in structure, be not take up upper and lower core bar 3, 4 inner space, and ensure that bottle cap is complete, quickly deviate from from mould, the demoulding is light.The Upper Die-sleeve 1 and knockout pin 12 Between set guide sleeve 18.There is guide sleeve 18, guiding role is played in the up and down action to knockout pin 12, ensures its action essence Standard, does not produce demoulding deviation.
