Abstract
The utility model discloses a secondary ejection mechanism for a plastic cement mould, which comprises a fixed plate, an ejector plate I, an ejector plate II, an ejector rob I, an ejector rob II, an ejector block and a sliding cavity, wherein the ejector plate I is arranged on the fixed plate; the ejector plate II is fixed on the ejector plate I; the ejector plate I forms the sliding cavity together with the ejector plate II; the ejector block is arranged in the sliding cavity; the lower end of the ejector rod I penetrates through the ejector plate II; the ejector plate I is fixed on the ejector block; the lower end of the ejector rod II penetrates through the ejector plate II to be fixed at the connection position of the ejector plate II and the ejector plate I. The secondary ejection mechanism has the advantages that the used parts are reduced, and the structure is very simple, so that the fabricating cost is reduced, the processing and assembly period is shortened, and the maintenance operation is performed conveniently.
Description
Technical field
The utility model relates to mould applications, is specially a kind of two-time ejector mechanism for plastic mould.
Background technology
Ask more and more thinner along with the market opponent is confidential, but plastic cement products glue position draws recessed generation bad at 0.3～0.7 millimeter gas line, mouth of a river ox horn, diving and product surface, directly affects the plastic cement products following process, and the high demand that can not satisfying the market of cost.
Special when the shape of finished product to be removed from mould, or the requirement during according to volume production, if after once ejecting, finished product is still in die cavity, or can't Automatic-falling the time, just need to increase again and once eject action, such action that ejects is Double-ejection.Double-ejection can allow and eject smooth and easyization of flow process, and the larger product for some ejection stroke demand, utilize Double-ejection can reduce the power that thimble applies when ejecting, and causes the defect of product while avoiding ejecting.
In prior art, patent about secondary ejection mechanism for mold or device is a lot, mainly contain the secondary ejecting mechanism that adopts the grab form, adopt the secondary ejecting mechanism of resin shutter, adopt the secondary ejecting mechanism of form of springs, wherein, the secondary ejecting mechanism more complicated of grab form, adopt the secondary ejecting mechanism of resin shutter easily to wear and tear, eject easy inefficacy and ejecting force little, the secondary ejecting mechanism of employing form of springs generally enters son with single-unit activity and does local Double-ejection, but after spring is compressed owing to there is no starting power, can not synchronize and eject with product, cause breaking of product to pull.
The utility model content
The technical problem that the utility model solves is to provide a kind of two-time ejector mechanism for plastic mould, to solve the problem proposed in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: a kind of two-time ejector mechanism for plastic mould, comprise: fixed head, ejector retainner plate I, ejector retainner plate II, push rod I, push rod II, jacking block, sliding chamber, described ejector retainner plate I is arranged on fixed head, be fixed with ejector retainner plate II on ejector retainner plate I, the upper common sliding chamber that forms of ejector retainner plate I and ejector retainner plate II, be provided with jacking block in sliding chamber, the lower end of push rod I is fixed on jacking block through ejector retainner plate II, ejector retainner plate I, and the delivery position of ejector retainner plate II and ejector retainner plate I is fixed in the lower end of push rod II through ejector retainner plate II.
Be provided with bolt in described jacking block, described bolt is screwed in the lower end of push rod I.
Described jacking block is T-shaped structure.
Compared with prior art, the beneficial effects of the utility model are: parts of the present utility model reduce, and structure is very simple, is beneficial to the reduction manufacturing cost, shorten the process and assemble cycle and maintain easily.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of two-time ejector mechanism for plastic mould, comprise: be arranged at the ejector retainner plate I2 on the fixed head 1 of mould and be fixed on ejector retainner plate II3, push rod I4, push rod II5 and the jacking block 6 on ejector retainner plate I2, described jacking block 6 passes through position bolt 7 in the inner and is connected with the injection machine push rod, has fixed the bottom of push rod I4 on the upper end of bolt 7 by grub screw 9; Jointly be formed with a sliding chamber 8 on ejector retainner plate I2 and ejector retainner plate II3, the upper end of jacking block 6 can slide up and down to be arranged in this cunning chamber 8, when jacking block 6 slides into the top in sliding chamber 8, the end face of jacking block 6 contacts mutually with ejector retainner plate II3, and the delivery position of ejector retainner plate II3 and ejector retainner plate I2 is fixed in the bottom of push rod II5 through ejector retainner plate II3; When the end face of jacking block 6 contacts mutually with ejector retainner plate II3, push rod II5 is ejected.
Operation principle of the present utility model is: after ejecting beginning, the injection machine push rod promotes jacking block 6 and advances, and promotes push rod I4 simultaneously and advances, and ejects for the first time beginning; Due to the existence of the stroke L of jacking block 6, while ejecting for the first time, jacking block 6 does not contact with ejector retainner plate I2 and ejector retainner plate II3, so when push rod I4 ejects, push rod II5 does not eject.While extremely contacting with ejector retainner plate II3 after jacking block 6 range ability L, push rod II5 is ejected, and just starts secondary ejecting.
With existing secondary ejecting mechanism, compare, parts of the present utility model reduce, and structure is very simple, low cost of manufacture, and the process and assemble cycle is short, safeguards simple and easy.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
