Description

A kind of small-sized interior mould emptier of mould of car lamp
Technical field
The present invention relates to a kind of small-sized interior mould emptier of mould of car lamp.
Background technology
At present, domestic car light is still based on general structure, there is that assembly space is big, and component is more, so existing a large amount of Screw fixed structure, with regard to foreign countries car light development for, the function of car light is more and more intelligent, for example, intelligence can adjust automatically LED and laser car light, assembling assembly is fewer and fewer, and space-consuming causes the structure of product also more and more multiple also with reduction It is miscellaneous, while for the structure of mould, also and then complicate, therefore requirement is also higher, therefore mold design, action knot Innovation and improvement on structure is imperative, to tackle the development of industry.
Automotive lamp product is with ratio in the past, and miniaturization and polychrome part are a lot, and structure and assembling are all more many than complicated in the past, conventional spiral shell Silk assembling all makes the assembling of buckle position into, it is particularly many in buckle positions, in the past with oblique top, it is interior take out and take off by force all do not realize. In mould snapped-in position, there are pilot hole and rib in top surface area, it is impossible to and to be realized and be stripped with oblique top, side zones, which become, glue position and mold insert, Narrow space, it is impossible to realize the demoulding with inner slide and interior take out, it is necessary to design a kind of brand-new miniaturization mould emptier and realize the demoulding, Could meet the needs of on product structure.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of adaptability is good, disclosure satisfy that complex structure product needs Ask, the small-sized interior mould emptier of the reliable mould of car lamp of having stable behavior.
The object of the present invention is achieved like this:
A kind of small-sized interior mould emptier of mould of car lamp, it includes pull bar, rotation inner slide, rotary shaft and body, die A breach is vertically provided with the right side of corresponding product back-off region, body is located in the breach, the profile and breach of body Internal periphery be mutually matched, the epimere of body offers a passage to the left, and the intrinsic epimere is provided with a rotation Area, upper end and the passage cross connection of Rotary District, passage and the product back-off regional connectivity on the outside of it, the right of Rotary District are set There is vertical pull bar lifting area, wherein rotation inner slide be located in Rotary District, pull bar is located at pull bar and lifted in area and pull bar Right side is close to inner body wall, and the middle part for rotating inner slide is articulated with Rotary District by the rotary shaft being longitudinally arranged, in rotation The upper end of sliding block forms latch segment to the left, the back-off shape phase interworking of product in the left side and product back-off region of latch segment Close;The hypomere for rotating inner slide forms swing arm, and the bottom left section of the Rotary District is provided with the left receiving position of a swing arm, pull bar The side of left and right two of upper end forms the first inclined-plane and the second inclined-plane, the upper end right side on the first inclined-plane and rotation inner slide respectively Face cooperates, and inwall cooperates on the right side of the pull bar lifting area upper end of the second inclined-plane and body, and the epimere of pull bar is positioned at rotation The right of inner slide, the epimere left side of pull bar is recessed to the right to form the right receiving position of one of vertical swing arm, the right receiving position of swing arm Pull bar epimere below the inclined-plane of the above first has a locking section consistent with pull bar size of main body.
When pull bar, which rises, is located at highest order, the upper end right flank on the first inclined-plane and rotation inner slide of pull bar coordinates, and draws Inwall cooperates on the right side of the pull bar of second inclined-plane of bar and body lifting area upper end, rotate inner slide swing arm some stretch Enter in the right receiving position of swing arm of pull bar, and swing arm right flank contacts with the right right flank for accommodating position of swing arm, rotates in inner slide Section left side wall is close to the inner left wall of the Rotary District of body, and the latch segment left end for rotating inner slide stretches out passage to product and fallen to the left Detain the mutual cooperation of region and product.
When pull bar, which declines, is located at lowest order, the locking section of pull bar contacts with rotating the swing arm right flank of inner slide, now Some is stretched into the left receiving position of swing arm of Rotary District for the swing arm of rotation inner slide, and swing arm left surface and the left receiving of swing arm The left surface contact of position, rotates the swing arm of inner slide and the locking section of pull bar and interference fit is formed at the inner chamber of body, lead Cause pull bar can not continue to decline, now the latch segment left end of rotation inner slide, which is retracted to the right, is back in passage.
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention realizes the scheme of the small-sized interior demoulding, reliable and stable using mechanical action, to protect the outward appearance of product and function Constant, mould meets intensity, size, injection molding machine and the feasibility for realizing automatic volume production.A kind of mould of car lamp of the present invention is small-sized The advantages of interior mould emptier is adaptable good, disclosure satisfy that complex structure product demand, and having stable behavior is reliable.
