Abstract
The utility model provides an oblique ejection structure of a front mould. Based on the oblique ejection structure, a mould of a product, the upper side part of which is provided with a backoff structure, is simple in structure and low in manufacturing cost, so that the low manufacturing cost of the product is reduced. The oblique ejection structure comprises the front mould, a rear mould, a plate A and a plate B, wherein a cavity is formed between the front mould and the rear mould in a surrounding manner; the product is arranged in the cavity; the upper side part of the product is provided with the backoff structure. The oblique ejection structure is characterized in that an oblique ejection embedding element is arranged in the front mould; one side at the lower part of the oblique ejection embedding element is tightly bonded on the backoff structure; the oblique ejection embedding element is positioned in an oblique guide slot of the front mould; the upper part of the oblique ejection embedding element is positioned in an empty cavity formed by the plate A and the front mould; a gap is formed between the lower end surface at the upper part of the oblique ejection embedding element and the front mould below the oblique ejection embedding element; the top of a resetting needle props against the lower end surface at the upper part of the oblique ejection embedding element; the lower end of the resetting needle is supported on the plate B after passing through the front mould; a spring is arranged between the upper end surface at the upper part of the resetting needle and the plate A.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of front mold tilt mandril structure.
Background technology
The product of existing top sidepiece band back-off structure, its all by sidepiece slide block by the demoulding of laterally having loosed core, because the cost of manufacture of horizontal core-pulling die structure is high, it makes the manufacturing cost of product high.
Summary of the invention
The utility model provides a kind of front mold tilt mandril structure, and it makes, and top sidepiece is simple with the mould structure of the product of back-off structure, cost of manufacture is low, and then makes the low cost of manufacture of product.
A kind of front mold tilt mandril structure, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, described front mould, between rear mold, surround die cavity, in described die cavity, it is product, the top sidepiece band back-off structure of described product, it is characterized in that: in described front mould, be furnished with oblique top mold insert, bottom one side of described oblique top mold insert is close to described back-off structure, described oblique top mold insert is positioned at the inclined guide groove of described front mould, the top of described oblique top mold insert is positioned at described A plate, in the formed spacing cavity of front mould, between the front mould of the lower surface on the top of described oblique top mold insert and its below, be provided with gap, the top of return pin is mounted on the lower surface on the top of described oblique top mold insert, described front mould rear support is run through in described B plate in the lower end of described return pin, the upper surface on the top of described oblique top mold insert, between A plate, be provided with spring.
Adopt after structure of the present utility model, A plate rises, drive front mould rises, now due to the effect of spring, oblique top mold insert can not rise, under the effect of inclined guide groove, oblique top mold insert can horizontal direction move away from back-off structure, when front mould climb just in time reaches clearance height, now, between oblique top mold insert and back-off structure, complete the demoulding, oblique top mold insert, the front mould demoulding of having risen afterwards, it makes, and top sidepiece is simple with the mould structure of the product of back-off structure, cost of manufacture is low, and then makes the low cost of manufacture of product.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises front mould 1, rear mold 2, A plate 3, B plate is (not shown in FIG., belong to existing mature technology), front mould 1, between rear mold 2, surround die cavity 4, in die cavity 4, it is product, the top sidepiece band back-off structure 5 of product 4, in front mould 1, be furnished with oblique top mold insert 6, bottom one side of oblique top mold insert 6 is close to back-off structure 5, oblique top mold insert 6 is positioned at the inclined guide groove 7 of front mould 1, the top of oblique top mold insert 6 is positioned at A plate 3, in the formed spacing cavity 8 of front mould 1, 1 of the front mould of the lower surface on the top 9 of oblique top mold insert 6 and its below is provided with gap 10, the top of return pin 11 is mounted on the lower surface on the top 9 of oblique top mold insert 6, front mould 1 rear support is run through in B plate in the lower end of return pin 11, the upper surface on the top 9 of oblique top mold insert 6, 3 of A plates are provided with spring 12.
