Description

Injection mold of convertible sprue

Technical Field

The utility model belongs to the technical field of the mould is used, concretely relates to injection mold of convertible sprue.

Background

The in-mold decoration (IMD) is an international popular surface decoration technology, and comprises a surface hardening transparent film, a middle printing pattern layer and a back injection molding layer, so that the product is resistant to friction, the surface is prevented from being scratched, the color can be kept bright for a long time, and the color is not easy to fade, the technology is widely diversified and applied to almost all branches of an injection molding process.

The injection mold for the household appliance function control panel with the traditional structure is single in injection molding product and cannot finish the manufacture of two products with different structures by one mold.

Therefore, based on the above problems, the utility model provides an injection mold of convertible sprue.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing an injection mold of convertible sprue, its reasonable in design can reach the product that a mould goes out two kinds of structures differences, realizes that a mould is dual-purpose, reduction in production cost.

The technical scheme is as follows: the utility model provides an injection mold of convertible sprue, including cope match-plate pattern, lower bolster, and set up the cope match-plate pattern, the last framed, lower framed, the C board of just matching between the lower bolster, and set up at last framed, between the framed and match the front mould benevolence of connecting, the back mould benevolence, and set up on the lower bolster and lie in C inboard lower thimble board, go up the thimble board, and set up on last thimble board and the reset spring that one end and lower framed be connected, and set up the first runner in framed one down, the second runner, the third runner.

According to the technical scheme, the lower thimble plate and the upper thimble plate are the same in size.

According to the technical scheme, the four reset springs are symmetrically arranged at four corners of one surface of the upper ejector plate.

Compared with the prior art, the utility model discloses an injection mold of convertible sprue's beneficial effect lies in: the die has the advantages of reasonable design, capability of forming two products with different structures by one die, dual purposes of one die, reduction of production cost and convenience in overhaul and maintenance.

Drawings

FIG. 1 is a schematic structural view of an injection mold with a changeable main runner according to the present invention;

FIG. 2 is a schematic top view of an injection mold with a changeable main runner according to the present invention;

fig. 3 is a schematic view of an injection mold with a changeable main runner according to the present invention.

Detailed Description

The invention will be further elucidated with reference to the drawings and the specific embodiments.

Examples

As shown in fig. 1, 2 and 3, an injection mold capable of changing a main runner includes an upper mold plate 1, a lower mold plate 2, an upper mold frame 3, a lower mold frame 4, a C plate 5, a front mold core 6, a rear mold core 7, a lower ejector plate 10, an upper ejector plate 9, a return spring 8, a first runner 11, a second runner 12, and a third runner 13, wherein the upper mold frame 3, the lower mold frame 4, the C plate 5, the front mold core 6, the rear mold core 7, the lower mold frame 3, the lower mold frame 4, the lower ejector plate 10, the upper ejector plate 9, the return spring 8, the first runner 11, the second runner 12, and the third runner 13 are arranged between the upper mold plate 1 and the lower mold plate 2 and are connected in a matching manner; the size of the lower template 2 is larger than that of the C template 5.

Further preferably, the lower ejector plate 10 and the upper ejector plate 9 have the same size; and four reset springs 8 are arranged and symmetrically arranged at four corners of one surface of the upper ejector plate 9.

The injection mold of the convertible main runner of this structure, can a mould two kinds of products that the structure is different, and used plastics raw and other materials must close another kind of product runner when also not moulding plastics one of them kind of product, as shown in fig. 2 first runner 11, third runner 13 is two product glue inlet now, and glue inlet simultaneously this moment, need pass through the rotatory second runner 12 of interior hexagonal with second runner 12, need mould plastics which kind of product just rotates that runner mouth to second runner 12, can accomplish different material conversion.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
