Abstract

The invention discloses a multi-version injection mold with a rapid mold changing structure, which comprises a multi-version insert, clamping mechanisms symmetrically arranged on the side wall of the insert, and ejector rods corresponding to the bottom of the insert. Clamping mechanism includes clamping ring, connecting bolt and fixed block, both sides the clamping ring symmetry sets up the both sides wall and the card of mold insert are gone into in the draw-in groove of mold insert both sides in order to be used for with the mold insert presss from both sides tightly, connecting bolt is used for connecting clamping ring and fixed block with one side. The multi-version mold changing mode for replacing the insert designed by the invention shortens the mold changing time, the insert needs about 6 hours before once mold changing, only 1 hour is needed at present, the structure is simple, and the operation can be carried out by only one person, so the invention greatly shortens the mold changing time, saves the manpower, material resources and financial resources, improves the production benefit, and can be used for the multi-version molds.

Description

Quick die change structure and multi-version injection mold

Technical Field

The invention relates to an injection mold, in particular to a quick mold changing structure and a multi-version injection mold.

Background

For an injection mold with multiple versions sharing a set of mold frame, the conventional mold changing mode is to completely remove the relevant mold plates and then replace the mold inserts, so that the once version changing can be completed within 6 hours at least by two persons, the number of the persons is increased, the time for changing the version is too long, and great time and labor waste is caused.

Disclosure of Invention

In order to solve the technical problem, the invention provides a rapid die change structure which comprises insert with multiple versions, clamping mechanisms symmetrically arranged on the side walls of the insert, and ejector rods corresponding to the bottoms of the insert.

The clamping mechanism comprises a pressing ring, a connecting bolt and a fixing block, the pressing ring is symmetrically arranged on two sides of the insert and clamped into the clamping grooves on two sides of the insert, the clamping groove is used for clamping the insert, and the connecting bolt is used for connecting the pressing ring and the fixing block on the same side.

The invention also provides a multi-version injection mold, which comprises an upper mold and a lower mold, wherein the upper mold is provided with an upper template, an upper backing plate and an upper mold base, and the lower mold is provided with a lower template, a lower backing plate, a push plate and a lower mold base; the quick die change structure with the structure is further included.

The insert is mounted on the lower base plate and penetrates through the lower template to correspond to a product; the clamping mechanism is arranged in an open slot of the lower backing plate, and the fixed blocks on two sides respectively correspond to the openings on two sides of the lower backing plate; the ejector rod is fixed on the lower die base and sequentially penetrates through the push plate and the lower cushion plate to be connected to the bottom of the insert.

And one end of each of the two side openings of the lower backing plate is provided with a plug corresponding to the fixing block.

Through the technical scheme, the mold changing time is shortened by the multi-version mold changing mode for replacing the insert, the insert is changed once probably in 6 hours, only 1 hour is needed at present, the time for changing one version is saved by 5 hours, the time for changing 10 versions is saved by 50 hours, and the like.

fig. 2 is a schematic top view of a rapid mold change structure according to an embodiment of the present invention.

The figures in the drawings represent:

11. a fixed block; 12. a connecting bolt; 13. pressing a ring; 14. an insert; 15. and a push rod.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1:

referring to fig. 1 and 2, the present invention provides a rapid mold changing structure, which includes multiple versions of an insert 14, clamping mechanisms symmetrically disposed on sidewalls of the insert 14, and ejector pins 15 corresponding to a bottom of the insert 14.

The clamping mechanism comprises a pressing ring 13, a connecting bolt 12 and a fixing block 11, the pressing rings 13 on the two sides are symmetrically arranged on the two side walls of the insert 14 and clamped into clamping grooves on the two sides of the insert 14 to clamp the insert 14, and the connecting bolt 12 is used for connecting the pressing ring 13 and the fixing block 11 on the same side.

Example 2:

the invention also provides a multi-version injection mold, which comprises an upper mold and a lower mold, wherein the upper mold is provided with an upper template, an upper backing plate and an upper mold base, and the lower mold is provided with a lower template, a lower backing plate, a push plate and a lower mold base; also comprises a quick die change structure of the embodiment 1.

Wherein, the insert 14 is arranged on the lower backing plate and penetrates through the lower template to correspond to a product; the clamping mechanism is arranged in an open slot of the lower backing plate, and the fixed blocks 11 on two sides respectively correspond to the openings on two sides of the lower backing plate; the ejector rod 15 is fixed on the lower die base and sequentially penetrates through the push plate and the lower cushion plate to be connected to the bottom of the insert 14; one end of the two side openings of the lower backing plate is provided with a plug corresponding to the fixing block 11.

When the quick-release insert 14 replacing device works, a plug on the outer side of the fixing block 11 is opened, then the fixing block 11 is pulled out in the outer direction by means of a tool, the fixing block 11 drives the connecting bolt 12 and the pressing ring 13 to move in the lateral direction under the action of external force, the pressing ring 13 is separated from the insert 14, then the insert 14 is ejected out through the ejector rod 15, so that inserts 14 of different versions are quickly taken out, and then after the insert 14 of a new version is replaced, only reverse operation is needed to enable the pressing ring 13 to lock the replaced insert 14.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the above-described embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
