Description

Small nozzle mold group with shared mold base

technical field

The invention relates to a plastic forming mold, in particular to a small nozzle mold group sharing a mold base.

Background technique

Plastic injection molding is a molding method that can be mass-produced quickly and has stable quality, so plastic injection molding is widely used in various fields.

And when a new product is to be produced, it is necessary to design an exclusive molding mold first. The mold is composed of a mold base and a mold core. The mold core is set on the mold base, and the mold base is then set on the injection molding machine. Among them, the mold core and the mold base are exclusive configurations, and the mold core and the mold base must be replaced together when replacing. Of course, if another product is to be produced, another set of molds must be developed and produced. For production For the industry, it is a very large cost expenditure; and if the volume of the product to be produced is large, the volume of the mold will also increase accordingly, so when the mold is to be replaced, all the molds must be dismantled at the same time. The mold core and mold base of the above-mentioned molds require a huge amount of work to replace, and it is very inconvenient to use large machines such as cranes.

Cover the guide post 11 , the two ends of the mother formwork support 32 are respectively assembled and connected to the stripper plate supports 22 , and the other ends of the tie rods 23 are fixed to the mother formwork support 32 .

A movable side mold set includes a movable side fixed plate 40 , two partition plates 50 , a supporting unit 60 and a plurality of clamping blocks 70 . in:

The movable side fixing plate 40 is used to be arranged on the movable side of the injection machine table.

Each of the spacer plates 50 is relatively arranged on the movable side fixed plate 40, and multiple groups of grooves 51 are set on each of the spacer plates 50, and two movable side guides are respectively set on each of the spacer plates 50. The holes 52 , the movable side guide holes 52 on the partition plate 50 can respectively correspond to the guide posts 11 passing through the fixed side fixing plate 10 .

The supporting unit 60 includes a first supporting block 61 and a second supporting block 62 . The first support block 61 and the second support block 62 are overlapped between the two partition plates 50, and one side of the second support block 62 is positioned at the same level as the two side surfaces of the two partition plates 50. on flat surface.

Each of the clamping blocks 70 respectively includes a set portion 71 connected to a pressing portion 72 . The assembly part 71 is formed corresponding to the assembly groove 51 of the partition plate 50, and the pressing part 72 is connected with the assembly part 71 to form an L-shape and has a pressing slope 721. The clamping blocks 70 The assembling part 71 is accommodated in the assembling groove 51 of the spacer plate 50, and a screw lock 73 is used to pass through the assembling part 71 and the spacer plate to screw the clamping blocks 70 and the spacer plate respectively. The partition plate 50 .

A male mold core, two shutters 81 are provided corresponding to the female mold through hole 311 of the female mold core 31, and the two sides of the male mold core 80 are respectively recessed with an abutment chute 82, and the abutment slide The groove 82 has an inclined abutting surface 821, and the male mold core 80 can be accommodated between the clamping blocks 70 of the two spacer plates 50 correspondingly in the abutting chute 82, and each clamping block 70 The pressing inclined surface 721 of the pressing part 72 of the pressing part 72 abuts against the abutting surface 821 of the male mold core 80, and the shutter 81 of the male mold core 80 can also correspondingly penetrate into the female mold channel of the female mold core 31. hole 311 , and the tool mold 80 can be matched with the female mold core 31 of the female mold unit 30 .

The above is the structural relationship of the small nozzle mold group sharing the mold base of the present invention. Since the present invention is mainly composed of the male mold core 80, the female mold core 31 and the stripper plate 21, it is a three-plate mold structure and is applicable. The processing method in the small nozzle, and can be assisted by the stripping unit 20 to complete the stripping action.
