Description

Mould location optimization structure

Technical Field

The utility model relates to the technical field of mold, in particular to mold positioning optimizes structure.

Background

With the rapid development of the automobile industry, the appearance requirement of injection products is higher and higher, wherein the requirement of the appearance surface is higher and higher, the problem point is enlarged after slight strain and small scratch are aluminized, and the mold industry always explores a more reliable structure to optimize the strain problem of the appearance surface of a deep cavity mold.

The defects and shortcomings of the prior art are as follows: at present, the middle of the deep cavity type annular decorative ring structure is collided with a perforation structure due to the limitation of a mold space and a product structure, most of the deep cavity type annular decorative ring structure is not positioned or is positioned only on a single side, the stability of the mold is poor due to the structure, the mold core slightly shakes during the injection molding and mold opening and closing processes, the product is extruded during mold opening due to the slight shaking, and the appearance surface is scratched.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that the movable mould benevolence that prior art exists rocks and leads to the product to be extruded and appear the problem that the outward appearance face strains, the utility model provides a movable mould benevolence can not slightly rock, increase stability's mould location optimization structure.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a mould location optimization structure, includes movable mould benevolence and cover half benevolence, movable mould benevolence intermediate position and the laminating of cover half benevolence, form the die cavity between movable mould benevolence both sides and the cover half benevolence, movable mould benevolence in the middle of have first cooperation portion, be equipped with the second cooperation portion of mutually supporting with first cooperation portion on the cover half benevolence, effort between first cooperation portion and the second cooperation portion is balanced each other. The acting force between first cooperation portion and the second cooperation portion is balanced each other, guarantees that the mould is opening and shutting the mould in-process, and the face of inserting between first cooperation portion and the second cooperation portion is the atress balanced, can not be partial to moving one side, has also guaranteed simultaneously that injection pressure acts on, and movable mould benevolence can not slightly rock, has increased stability.

Furthermore, the first matching part is a protruding part, and the second matching part is a groove matched with the protruding part in shape.

Furthermore, the convex part is a rectangular boss, a trapezoidal boss, a conical boss, an arc boss or a tooth-shaped boss.

Furthermore, the mould is used for producing deep-cavity decorative ring parts.

Furthermore, the height of the deep cavity type decorative ring part is 5-10 times of the height of the convex part of the movable mould core. The height of the bulge part is related to the height of the deep-cavity decorative ring part, and when the part is higher, the height of the first matching part is properly set to be higher.

Has the advantages that:

(1) when the mold is opened, the product can not be stressed to cause surface strain, thereby improving the qualification rate of the product and improving the efficiency of mold testing;

(2) the utility model discloses a scheme of dual location has increased the stability of mould at moulding plastics and the mould in-process that opens and shuts.

As shown in fig. 2, a mold positioning optimization structure comprises a movable mold core 2 and a fixed mold core 1, wherein the middle position of the movable mold core 2 is attached to the fixed mold core 1, a cavity 3 is formed between two sides of the movable mold core 2 and the fixed mold core 1, a first matching part is arranged in the middle of the movable mold core 2, a second matching part matched with the first matching part is arranged on the fixed mold core 1, and acting forces between the first matching part and the second matching part are balanced.

First cooperation structure quantity can be one or more, can be forms such as a plurality of bumps, the utility model discloses in, first cooperation portion is bellying 21, and second cooperation portion is the recess 11 that matches with bellying 21 shape. The convex part 21 is a rectangular boss, a trapezoidal boss, a conical boss, an arc boss or a tooth-shaped boss, and can be other forms of bosses.

The mould is used for producing deep-cavity decorative ring parts. The deep cavity type decorative ring part is integrally annular and has a certain height, if the movable mold core 2 shakes, the mold opening is affected, the height of the deep cavity type decorative ring part is 5-10 times of the height of the first matching part of the movable mold core 2, the height of the protruding part 21 is set according to the height of the part, when the protruding part 21 is higher, the limiting effect on the movable mold core 2 is better, and therefore the mold opening of the deep cavity type decorative ring part with the higher height is facilitated.

The working principle is as follows:

as shown in fig. 1, in the mold scheme of the prior art, after the mold is closed, a single edge of the fixed mold core 1 is matched with the movable mold core 2, and an acting force is generated along the arrow direction in fig. 1, so that the movable mold core 2 slightly extrudes towards the black direction, after the mold is opened, the acting force of the movable mold core 2 rebounds, and a pressure is applied to a product, so that the outer surface of the product is rubbed with the fixed mold core 1 to generate strain in the mold opening process.

The utility model discloses the purpose is realized the mutual positioning between fixed mould benevolence 1 and movable mould benevolence 2, compares prior art's unilateral location (through the slope curve location between movable mould benevolence 2 and the fixed mould benevolence 1 promptly), the utility model discloses in through the scheme of dual location, fix a position through the 21 both sides of bellying of movable mould benevolence 2 promptly, movable mould benevolence 2 and fixed mould benevolence 1 restrict each other like this, avoid the in-process movable mould benevolence 2 of moulding plastics because the effect of injection pressure has slightly rocked, has increased the stability of the die sinking after the end of moulding plastics simultaneously.

As shown in fig. 2, newly increase the location (black arrow point position boss, wide 10mm, high 20mm) between movable mould benevolence 2 and the fixed mould benevolence 1, guarantee that the mould is opening and shutting the mould in-process, the face of inserting between bellying 21 and recess 11 is the force balance, movable mould benevolence 2 can not be partial to moving one side, the product can not be pressed and lead to the surface to pull when the mould opening like this, also guaranteed simultaneously at the pressure effect of moulding plastics, movable mould benevolence 2 can not slightly rock, increased stability.

Above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be covered within the protection scope of the present invention.
