Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.

Example 1:

as shown in fig. 1-4, an inclined hole core pulling structure comprises a mounting plate 1, a guide slider 3 fixed on the mounting plate 1, and an inclined top 2 penetrating through the mounting plate 1 and capable of lifting and descending in a reciprocating manner; the guide sliding block 3 is provided with an insert pin 4 which is obliquely arranged; the insert pin 4 penetrates through the inclined top 2 and is in sliding fit with the inclined top 2; the inclined top 2 is in sliding fit with the guide sliding block 3.

The implementation principle is that the guide slide block 3, the inclined top 2 and the insert pin 4 are arranged to be matched with each other and arranged on the periphery of an inclined hole needing core pulling, so that the purposes of core pulling on the inclined hole and product ejection can be achieved; the inclined top 2 is relatively sliding with the mounting plate 1 and relatively sliding with the insert pins 4, in the ascending process of the inclined top 2, the insert pins 4 relatively descend and exit from inclined holes in products, core pulling is achieved, the inclined top 2 continuously ascends and simultaneously ejects the products, and the inclined hole core pulling structure is simple in structure and convenient to process.

In practical application, one end of the slanted ejecting part 2 is an ejecting end 201 which extends horizontally, and the ejecting end 201 is located on the upper side of the guide sliding block 3; the insert pin 4 penetrates through the ejecting end 201 and is in sliding fit with the ejecting end 201.

In this embodiment, adopt the mode that the 2 slope lifts of oblique top, rather than the mode that the ejector pin goes up and down vertically, prevent that the product surface from producing the overlap, avoid causing the surface unsmooth.

In the specific structure of the lifter 2, the other end of the lifter 2 is a sliding end 202, and the sliding end 202 penetrates through the mounting plate 1 and is in sliding fit with the guide slider 3.

The specific connection mode of the guide sliding block 3 and the insert pin 4 is that a clamping groove 302 which is obliquely arranged is arranged on the guide sliding block 3, and an end block 5 connected with the clamping groove 302 is arranged at the bottom of the insert pin 4; the connection mode has a simple structure, the size of the mold blank is reduced, the machine table is correspondingly reduced, and the production cost is reduced.

The specific structure of the clamping groove 302 is that the clamping groove 302 is a T-shaped groove penetrating through two opposite sides of the guide sliding block 3, the insert pin 4 penetrates through the bayonet 301 of the clamping groove 302, and the end block 5 is located on the lower side of the bayonet 301 of the clamping groove 302 and is in sliding fit with the clamping groove 302.

When the device is used specifically, the guide sliding block 3 is fixed on the mounting plate 1, the inclined top 2 is connected with an ejection mechanism of a die, the inclined top 2 performs upward ejection movement, the guide sliding block 3 and the insert pins 4 are relatively static and do not generate oblique acting force, and the insert pins 4 are withdrawn from the inclined holes of the product to complete the action.

When the structure is mounted and dismounted, only the pitched roof 2 needs to be mounted and dismounted, the operation is simple and convenient, and the time is saved.

The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
