Abstract
The utility model discloses a demoulding structure for vulcanization products. The demoulding structure comprises an ejector pin plate and ejector pins on the ejector plate, wherein a plurality of ejector pins which are uniformly distributed in vertical and transverse directions are arranging on the plate surface of the ejector pin plate in a matched manner; the ejector pins are different in length, and the ejector pins differing in length are vertically and transversely distributed regularly or irregularly; the ejector pins are respectively aligned with mould cavities; when a mould is pushed through an ejecting mechanism under certain demoulding pressure, products in the mould cavities fall successively depending on the different lengths of the ejector pins in contact. The demoulding structure disclosed by the utility model effectively avoids adverse phenomena of the products such as being scratched and being broken when demoulding force on a single product is insufficient due to large overall stress area of the product under the certain demoulding pressure; the demoulding structure disclosed by the utility model is simple in structure and high in product demoulding yield.
Description
Technical field
The utility model relates to Design of Dies technical field, relates in particular to a kind of demolding structure for vulcanizate.
Background technology
Vulcanizate is because matter is soft and processing technology is different from traditional injection mold, therefore in the time of the demoulding, can design different demoulding toolings according to different parting structures, pitch of enters on traditional middle mould ejector retainner plate is consistent, the product large for small product size, die cavity number is many, when the demoulding, lifting surface area is large, inertia is large, is easy to cause that product is de-broken, outward appearance scratches, and causes the problems such as qualification rate is low.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and improves the demolding structure of product yield by changing lifting surface area.
For reaching this object, the utility model by the following technical solutions:
A kind of demolding structure for vulcanizate, comprise ejector retainner plate and be arranged on the thimble on ejector retainner plate, on the plate face of described ejector retainner plate, be combined with several thimbles of uniform arrangement in length and breadth, described thimble has respectively different length, and the thimble of different length is regular and arranges in length and breadth or irregularly arrange in length and breadth, described thimble aligns with die cavity respectively, in the time that mould carries out pusher by ejecting mechanism under certain ejection pressure, the product in die cavity can successively come off because the length of contacted thimble is different.
Wherein, described thimble is 9 vertical 9 horizontally-arranged row.
Wherein, described adjacent thimble height is interspersed.
Wherein, described adjacent thimble height is interspersed or contour distribution.
Wherein, the difference in height between the longest described thimble and the shortest thimble is less than or equal to 20mm.
Wherein, the dome pin that described thimble is carbon steel material, described dome pin and described ejector retainner plate adopt interference fit.
Wherein, described thimble is the nylon column with different length, and the bottom of described nylon column is connected by screw with ejector retainner plate.
The beneficial effects of the utility model: the utility model comprises ejector retainner plate and is arranged on the thimble on ejector retainner plate, on the plate face of described ejector retainner plate, be combined with several thimbles of uniform arrangement in length and breadth, described thimble has respectively different length, and the thimble of different length is regular and arranges in length and breadth or irregularly arrange in length and breadth, described thimble aligns with die cavity respectively, in the time that mould carries out pusher by ejecting mechanism under certain ejection pressure, the product in die cavity can successively come off because the length of contacted thimble is different.Efficiently solve under certain ejection pressure, because product entirety lifting surface area causes single product knockout press inadequate greatly, and then make product scratch, de-ly break etc. badly, the utility model is simple in structure, and product stripping yield is high.
Brief description of the drawings
Fig. 1 is the front view of a kind of demolding structure for vulcanizate of the utility model.
Fig. 2 is the top view of a kind of demolding structure for vulcanizate of the utility model.
In figure: 10. ejector retainner plate, 12. thimbles.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 to Fig. 2 and further illustrate the technical solution of the utility model by detailed description of the invention.
A kind of demolding structure for vulcanizate, comprise ejector retainner plate 10 and be arranged on the thimble 12 on ejector retainner plate 10, on the plate face of described ejector retainner plate 10, be combined with several thimbles 12 of uniform arrangement in length and breadth, described thimble 12 has respectively different length, and the thimble 12 of different length is regular and arranges in length and breadth or irregularly arrange in length and breadth, described thimble 12 aligns with die cavity respectively, in the time that mould carries out pusher by ejecting mechanism under certain ejection pressure, the product in die cavity can successively come off because the length of contacted thimble 12 is different.Efficiently solve under certain ejection pressure, because product entirety lifting surface area causes single product knockout press inadequate greatly, and then make product scratch, de-ly break etc. badly, the utility model is simple in structure, and product stripping yield is high.
Described thimble 12 is 9 vertical 9 horizontally-arranged row.
Described adjacent thimble 12 height are interspersed.Can be regular distribution.
Described adjacent thimble 12 height are interspersed or contour distribution.Also can be irregular distribution.
Difference in height between the longest described thimble 12 and the shortest thimble 12 is less than or equal to 20mm.As the present embodiment preferably, the poor product yield ejecting of pitch of enters of this scope is the highest.
The dome pin 12 that described thimble 12 is carbon steel material, described dome pin 12 adopts interference fit with described ejector retainner plate 10.
Described thimble 12 is for having the nylon column of different length, and the bottom of described nylon column is connected by screw with ejector retainner plate 10.For this vulcanizate, because mould structure is relatively simple, and product is softer, therefore for effectively reducing production costs, can select the wear-resisting and good nylon column of toughness to replace the dome pin of the dome pin of carbon steel material, is easy to change and be easy to processing.And nylon column, in the time of matched moulds, can not forbidden to cause because of location the damage of mold cavity.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, within these modes all will fall into protection domain of the present utility model.
