Abstract

The utility model provides a directly-pushed elasticized block assembly which comprises a directly-pushed head and an embedded component, wherein the rear part of the embedded component is sleeved with a spring; an elastic block is arranged at the rear end surface of the embedded component; a stepped through hole in which the embedded component, the spring and the elastic block can move front and back is formed in the directly-pushed head; the embedded component and the spring are positioned in the stepped through hole; a V-shaped groove is formed in the front end surface of the embedded component; the V-shaped groove is adapted to a convex part on a product manufactured by using a mould; and the stepped through hole is positioned behind the convex part and is provided with a rear limiting step surface. When the elastic block pops up backwards, the rear step surface of the convex part props against the rear limiting step surface; and when the spring is tightly pressed until the rear end surface of the elastic block is flush with the rear end surface of the stepped through hole, a distance from the rear step surface of the convex part to the rear limiting step surface is adapted to the depth of the V-shaped groove. The directly-pushed elasticized block assembly has the beneficial effect that the problem of difficult demoulding caused by the large tightening force of an inward concave part is solved.

Description

Straight top adds bullet block assembly

Technical field

The utility model relates to a kind of straight top and adds bullet block assembly.

Background technology

In existing technology, on mould, have indent position when the demoulding because package power is larger, easily cause deformation of products impaired, the mould of making bumper of take is example, BOSS post and U-shaped glue position are after directly pushing up moulding, due to BOSS post and U-shaped glue bit comparison dark, under the effect of package power, directly eject rear product still can stay straight top cannot the demoulding

Summary of the invention

The utility model provides a kind of straight top to add bullet block assembly, has solved indent position and has had package power, the problem of demoulding difficulty.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: straight top adds bullet block assembly, comprises straight top and mold insert, and the rear sleeve of described mold insert has spring;

The rear end face of described mold insert has bullet piece, and the front portion of described bullet piece has with respect to the rear portion of the outer surface of described mold insert and described bullet piece protuberance radially; The foreground terrace of described spring one end and described protuberance is conflicted;

In described straight top, have and can hold the step through-hole that described mold insert, described spring and described bullet piece move forward and backward, described step through-hole is through front surface and the rear end face of described straight top, described mold insert and described spring are positioned at described step through-hole, the front end face of described mold insert has type groove, and the position of protruding on the product that described type groove and Mold Making go out is adaptive;

The front portion of described bullet piece is positioned at described step through-hole, and rear end face can stretch out described step through-hole;

The other end of described spring and described step through-hole are positioned at the front limit step surface in described bullet piece the place ahead and conflict;

The rear that described step through-hole is positioned at described protuberance has rear limiting stand terrace, and when described bullet piece rearward ejects, the backstage terrace of described protuberance and described rear limiting stand terrace are conflicted; When spring is compacted to the rear end face of described bullet piece and the rear end face of described step through-hole and flushes, the backstage terrace of described protuberance is to the distance of described rear limiting stand terrace and the depth adaptation of described type groove.

Further, be the simplification of example processing technology, described mold insert comprises outer mold insert and is placed on the interior mold insert in described outer mold insert, the front end face conflict of the rear end of described interior mold insert and described bullet piece, the front end face splicing composing type groove of described inside and outside mold insert.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, solved the problem of product indent position demoulding difficulty, it is simple in structure, and processing cost is low.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model;

Fig. 2 is specific embodiment structural representation;

In figure: 1 is mold insert; 11 is type groove; 12 is interior mold insert; 13 is outer mold insert; 21 is the protrusion of bullet piece; 22 is the rear portion of bullet piece; 3 is spring; 41 is the front limit step surface in step through-hole; 42 is the rear limiting stand terrace in step through-hole; 5 is briquetting; 51 is the step through-hole of briquetting inside; 6 is straight top.

The specific embodiment

As shown in Figure 1, the utility model provides a kind of straight top to add bullet block assembly, comprises straight top 6 and mold insert 1, and the rear sleeve of mold insert 1 has spring 3;

The rear end face of mold insert 1 has bullet piece, and the front portion of bullet piece has with respect to the rear portion 22 of the outer surface of mold insert 1 and bullet piece protuberance 21 radially; The foreground terrace of spring 3 one end and protuberance 21 is conflicted;

In straight top 6, have and can hold the step through-hole that mold insert 1, spring 3 and bullet piece move forward and backward, step through-hole is through front surface and the rear end face of straight top 6, mold insert 1 and spring 3 are positioned at step through-hole, the front end face of mold insert 1 has type groove 11, and the position of protruding on the product that type groove 11 and Mold Making go out is adaptive;

The front portion of bullet piece is positioned at step through-hole, and rear end face can stretch out step through-hole;

The other end of spring 3 and step through-hole are positioned at the front limit step surface 41 in bullet piece the place ahead and conflict;

The rear that step through-hole is positioned at protuberance 21 has rear limiting stand terrace 42, and when bullet piece rearward ejects, the backstage terrace of protuberance 21 and rear limiting stand terrace 42 are conflicted; When spring 3 is compacted to the rear end face of bullet piece and the rear end face of step through-hole and flushes, the backstage terrace of protuberance 21 is to the distance of rear limiting stand terrace 42 and the depth adaptation of type groove 11.

In order to reduce the difficulty of processing of type groove (11), mold insert 1 is designed to comprise outer mold insert 13 and is placed on the interior mold insert 12 in outer mold insert 13, the front end face conflict of the rear end of interior mold insert 12 and bullet piece, the front end face splicing composing type groove 11 of inside and outside mold insert 12,13.

In addition in order to reduce difficulty of processing, as shown in Figure 2, design one briquetting 5, has step through-hole 51 in briquetting 5, and bullet piece is positioned at step through-hole 51, and rear limiting stand terrace 42 relies on briquetting 5 and exists.

The course of work of this example: while directly ejecting, there is space in straight top 6 make thereafter end faces separated with rear mold, now spring 3 moves bullet piece because of the release of pressure backward, drive whole mold insert 1 to move backward, play the effect of the demoulding, until the rear end face of bullet piece protuberance 21 and rear limiting stand terrace 42 are conflicted, rear its stroke stops.Now straight top continues to eject, until complete the whole action that ejects.Straight top rollback can push back bullet piece again bullet piece rear end face and flush with the step through-hole rear end face in straight top, starts next circulation after matched moulds.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
