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 slide block retaining mechanism

Technical field

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

Background technology

At present, the slide block core-pulling mechanism is more common in die industry, wherein Angle Pin slide block core-pulling mechanism all need slide block to be on the position of opening at last when matched moulds, but many times slide block mechanism need be installed in a day side direction, be subjected to gravity effect meeting in the matched moulds process and slide a segment distance earlier, the Angle Pin hole site that causes Angle Pin and slide block is not to going up, and under such situation, Angle Pin and slide block can bump when continuing matched moulds, directly cause mould to damage, again ordinary production.

Summary of the invention

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

The mould slide block retaining 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, offer the locking slot with the "T"-shaped respective outer side edges of latch segment on the described slide block, the both wings that the "T"-shaped structure of described latch segment is outstanding are the elastic telescopic structure.This patent passes through the retractable locking of both wings T piece one by one, can effectively overcome in process of production because slide block is located badly when the sky side direction is installed, can not rest on the home position preferably and the collision problem that causes the Angle Pin hole of Angle Pin and slide block to produce not going up.

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

Cooperate for the ease of slide block and clamping block, 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 the 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, it is bad to have overcome in the prior art day side slide location, the drawback easy and Angle Pin collides has increased mould safety coefficient at work, in like manner, the present invention can be used on slide block and need reset earlier, mould before and after closing again, and to utilize during die sinking the mechanical force of injection machine to draw back the situation of slide block, have substantive distinguishing features and progress with respect to prior art.

The specific embodiment

For example detailed structure of the present invention is further described below in conjunction with accompanying drawing.

A kind of mould slide block retaining mechanism comprises as shown in Figure 1 slide block 1 and latch segment as shown in Figure 22, described latch segment 2 one sides are "T"-shaped, as shown in Figure 4, offer the locking slot 9 with latch segment 2 "T"-shaped respective outer side edges on the described slide block 1, in conjunction with shown in Figure 3.The both wings that the "T"-shaped structure of described latch segment is outstanding are the elastic telescopic 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 with 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 the 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, slide block 1 slides earlier then, before and after mould again during matched moulds, bullet piece 5 on the latch segment 2 utilizes the inboard of slide block 1 to import inclined-plane 8 past interior contraction under the mold clamping force of injection machine, after matched moulds put in place, bullet piece 5 ejected outward under the active force of spring 6 and recovers to stretch out state, and the state behind the matched moulds as shown in Figure 5.

Fig. 6 is that first kind of working method of the present invention implemented schematic diagram, and when matched moulds, slide block 1 is subjected to the gravity effect and slides earlier, 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 outside of bullet piece 5 imports the importing inclined-plane 8, inboard that slide block 1 is at first run on inclined-plane 7, has avoided slide block 1 and latch segment 2 because of the dislocation direct collision, has well protected mould.

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