Description

A kind of sliding block gradient knock-out gear

Technical field

The utility model relates to the technical field of mould structure more particularly to a kind of Mold Core-pulling Mechanisms.

Background technique

Mold in the industrial production to be molded, be blow molded, squeeze out, die casting or the methods of forging and forming, smelting, punching press obtain The various moulds and tool of required product, in brief, mold are the tools for making formed article, and many products are being opened Direction has the feature of back-off, this just needs to design side core-drawing mechanism in mold design to realize demoulding, especially for some Complicated product, the direction of side core-pulling and template have certain angle, and at this time the sliding block of side core-pulling can not be by flat It moves and directly demoulds, it is difficult to the driving force that the driving force for being opened direction is converted to core pulling direction be realized into demoulding, and also resulted in Mould parts processing is complicated.

Utility model content

Technical problem to be solved by the utility model is to provide a kind of sliding block gradient knock-out gears to solve current side The problem of sliding block of side core-pulling can not demould when forming an angle to the sliding block and template of core pulling.

In order to solve the above technical problems, the technical solution of the utility model is: a kind of sliding block gradient knock-out gear, including it is upper Template, the take-up housing positioned at the lower template of cope plate lower end, between cope plate and lower template, inclined guide pillar, link block, cunning Block, type chamber, the cope plate are equipped with the U-lag for avoiding take-up housing, and the lower template is equipped with for take-up housing along lateral sliding Sliding slot, for the take-up housing between cope plate and lower template, take-up housing is equipped with inclined hole, and the inclined guide pillar is fixed on cope plate simultaneously It is inserted into the inclined hole of take-up housing, inclined guide pillar is consistent with the angle of the inclined hole of take-up housing, and inclined guide pillar is connected with take-up housing sliding, inclined guide pillar Angled with mold die sinking direction, take-up housing is realized by movement of the inclined guide pillar in die sinking in die sinking direction to drive Lateral movement, the link block are located at the front end of take-up housing, and link block is connected with take-up housing screw thread, and the sliding block is located at take-up housing Front end, sliding block rear end are equipped with the sliding slot mutually identical with link block and are connected with link block sliding, and take-up housing can pass through company It connects block band movable slider to be displaced sideways, sliding block rear end face is posted by take-up housing front end face, and the sliding block is additionally provided on its interior Mold insert, the mold insert need the feature of core pulling part for shaped article, sliding block protrude into the intracavitary portion of type and with it mutually It coincide, sliding block can be moved along core pulling direction type is intracavitary, and slip front and type chamber are closely against type chamber combines shape with sliding block At the cavity for formed product.

Compared with prior art, this knock-out gear with gradient converts the core pulling direction with gradient of sliding block At the core pulling direction without gradient, the demoulding that product has gradient core pulling position is not only realized, while sliding block is corresponding in template Sliding slot be all horizontal direction, greatly facilitate the processing of template and sliding block part, in addition by sliding block product with gradient take out The position of core is individually made into the mold insert inlayed inside it, increases the exhaust when injection molding of this position product, while core pulling part It protrudes into interiors of products to be easily damaged, mold insert is convenient for changing, and is reduced sliding block because local damage bring is lost, is improved the efficiency that repairs a die It repairs a die difficulty with reduction.

Specific embodiment

As shown in Fig. 1 to 3, a kind of sliding block gradient knock-out gear, including cope plate 1, the lower template positioned at cope plate lower end 2, take-up housing 3, inclined guide pillar 4, link block 5, sliding block 6, the type chamber 7 between cope plate and lower template, the cope plate 1 are equipped with The U-lag 11 of take-up housing 3 is avoided, the lower template 2 is equipped with two press strips 21, and the press strip 21 is used to form two for sliding block Seat 3 is along the sliding slot 22 of lateral sliding, and for the take-up housing 3 between cope plate 1 and lower template 2, take-up housing 3 is equipped with inclined hole 31, The inclined guide pillar 4 is fixed on cope plate 1 and is inserted into the inclined hole 31 of take-up housing 3, the angle of the inclined hole 31 of inclined guide pillar 4 and take-up housing 3 Unanimously, inclined guide pillar 4 is connected with the sliding of take-up housing 3, and inclined guide pillar 4 and mold die sinking direction are angled, and take-up housing 3 is by tiltedly leading Lateral movement is realized in mobile driving of the column 4 in die sinking in die sinking direction, and the link block 5 is located at the front end of take-up housing 3, connects Block 5 is connected with 3 screw thread of take-up housing, and the sliding block 6 is located at 3 front end of take-up housing, and 6 rear end of sliding block is equipped with mutually to coincide with link block 5 T-slot and be connected with the sliding of link block 5, take-up housing 3 can be by link block 5 with the lateral movement of movable slider 6, after sliding block 6 End face is posted by the front end face of take-up housing 3, and the sliding block 6 is additionally provided with mold insert 61 on its interior, the mold insert 61 be used at The feature of type product core pulling part, the positioning pin 661 are located inside sliding block 6, positioning pin 661 for mold insert 61 in sliding block 6 with Being fixedly connected between sliding block 6, the sliding block 6 are also equipped with chimb 62 in its two sides, and the chimb 62, which is caught in sliding slot 22, to be made Sliding block 6 can only be displaced sideways in sliding slot 22, and sliding block 6 protrudes into 7 inside of type chamber and mutually coincide with it, 6 front end of sliding block With type chamber 7 closely against type chamber 7 combines the cavity for being formed and being used for formed product with sliding block 6.

This sliding block gradient knock-out gear, in the process of die sinking, the mobile drive of cope plate is tiltedly led when being acted by die sinking The movement of column, and the movement of inclined guide pillar drives take-up housing to be displaced sideways in sliding slot, while sliding block is by being fixed on take-up housing On link block driving so that sliding block lateral movement while also can move up and down, to realize sliding block with gradient Core pulling direction on movement.

The utility model has the beneficial effects that efficiently solving depanning core pulling side by this sliding block gradient knock-out gear Go out modulus problem when to gradient, while facilitating the processing of sliding block and bolster.

The utility model is not limited to above-mentioned specific embodiment, and those skilled in the art visualize from above-mentioned Hair, without creative labor, the various transformation made are all fallen within the protection scope of the utility model.
