Abstract

The invention relates to a design of a sliding block core-pulling mechanism of a mould. In order to overcome the defects of the prior art, the invention provides a brand-new sliding block locking mechanism of the mould. The brand-new sliding block locking mechanism can effectively prevent collision during mould assembly and avoid damage to the mould. The sliding block locking mechanism structurally comprises a sliding block and a locking block; the sliding block locking mechanism is characterized in that: one side of the locking block is T-shaped; a locking groove which is matched with a T-shaped structure of the locking block is formed on the sliding block; and two protruding wings of the T-shaped structure of the locking block have elastic stretching structures. By the locking T-shaped block of which two wings are stretchable, the problem of collision caused by non-alignment of an oblique guide pillar with an oblique guide pillar hole of the sliding block in a production process because the sliding block cannot be well positioned during installation along a day-side direction and cannot better stay at an initial position can be effectively solved.

Description

A kind of mould sliding block locking mechanism

Technical field

Patent of the present invention relates to the design of mould slide block core-pulling mechanism, particularly a kind of mould sliding block locking mechanism.

Background technology

At present, sliding block core-pulling mechanism is more common in die industry, wherein the Angle Pin sliding block core-pulling mechanism, when matched moulds, all need slide block to be on the position of finally opening, but many times slide block mechanism need be arranged on a day side direction, in the matched moulds process, be subject to Action of Gravity Field and can first slide a segment distance, cause the slanting guide pillar hole position of Angle Pin and slide block to not going up, in such situation, Angle Pin and slide block can bump when continuing matched moulds, directly cause mould to damage, can not normally produce again.

Summary of the invention

Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, bumps while providing a kind of brand-new mould sliding block locking mechanism effectively to prevent matched moulds, avoids the damage of mould.

The mould sliding block locking mechanism that the present invention is designed, comprise slide block and latch segment, its improvement part is that described latch segment one side is "T"-shaped, on described slide block, offer the locking slot with the "T"-shaped respective outer side edges of latch segment, the both wings that the "T"-shaped structure of described latch segment is outstanding are elastic extension structure.This patent passes through the retractable locking of both wings T piece one by one, can effectively overcome while due to slide block, installing along the sky side direction in process of production location bad, can not rest on home position preferably and the slanting guide pillar hole that causes Angle Pin and slide block to not going up the collision problem produced.

Concrete structure is that the both wings that described "T"-shaped structure is outstanding comprise bullet piece, briquetting, spring and lock screw, and lock screw is suppressed the bullet piece by briquetting spring is locked to bullet piece below.

For the ease of slide block and clamping block, coordinate, described locking slot both sides are provided with the inboard inclined-plane that imports, and the both sides of the both wings that the "T"-shaped structure of latch segment is outstanding are respectively equipped with the outside and import inclined-plane.

Further, described locking slot and "T"-shaped structure are skewed, and both angles of inclination are identical.

The present invention is simple in structure, the both wings flexible campaign of the "T"-shaped structure of latch segment, having overcome day side slide in prior art locates bad, the drawback easy and Angle Pin collides, increased mould safety coefficient at work, in like manner, the present invention can be used on slide block and need to first reset, mould before and after closing again, and to utilize during die sinking the mechanical force of injection machine to pull open the situation of slide block, with respect to prior art, have substantive distinguishing features and progress.

The specific embodiment

Below in conjunction with accompanying drawing, for example detailed construction of the present invention is further described.

A kind of mould sliding block locking mechanism, comprise slide block 1 as shown in Figure 1, and latch segment as shown in Figure 22, described latch segment 2 one sides are "T"-shaped, as shown in Figure 4, on described slide block 1, offer the locking slot 9 with latch segment 2 "T"-shaped respective outer side edges, in conjunction with shown in Figure 3.The both wings that the "T"-shaped structure of described latch segment is outstanding are elastic extension structure, comprise bullet piece 5, briquetting 4, spring 6 and lock screw, and lock screw is locked at bullet piece 5 belows by briquetting 4 compacting bullet pieces 5 by spring 6.Described locking slot 9 both sides are provided with the inboard inclined-plane 8 that imports, and the both sides of the both wings that the "T"-shaped structure of latch segment 2 is outstanding are respectively equipped with the outside and import inclined-plane 7.Described locking slot 9 and "T"-shaped structure are skewed, and both angles of inclination are identical.

Bullet piece 5 on latch segment 2 is in the state of stretching out under the active force of spring 6, utilize the mould opening force of injection machine to open slide block 1, then slide block 1 first slides, before and after mould again during matched moulds, bullet piece 5 on latch segment 2 utilizes importing inclined-plane 8, inboard past interior contraction under the mold clamping force of injection machine of slide block 1, after matched moulds put in place, bullet piece 5 ejected outward and recovers to stretch out state under the active force of spring 6, and the state after matched moulds as shown in Figure 5.

Fig. 6 is that the first working method of the present invention is implemented schematic diagram, and when matched moulds, slide block 1 is subject to Action of Gravity Field and first slides, and locking slot 9 positions of latch segment 2 and slide block 1 are not to going up.Use this structure, in the matched moulds process, the importing inclined-plane, inboard 8 of slide block 1 is encountered in the importing inclined-plane, the outside 7 of bullet piece 5 at first, has avoided slide block 1 and latch segment 2 because of the dislocation direct collision, has well protected mould.

Fig. 7 is that the second working method of the present invention is implemented schematic diagram, has the slide block 1 of some specific (special) requirements first to reset with respect to rear mold mold insert 3, as shown by arrows in FIG., then mould before and after closing.Use this structure, pull out slide block 1, during matched moulds, utilize the contraction of bullet piece 5, complete smoothly matched moulds thereby utilize during die sinking the mould opening force of injection machine to make bullet piece 5 and slide block 1 produce relative motion.
