Description

Adjustable cavity injection mold

Technical Field

The utility model belongs to the technical field of injection mold, concretely relates to adjustable die cavity injection mold.

Background

Injection molding, also known as injection molding, is a method of molding by injection and molding. The injection molding method has the advantages of high production speed, high efficiency, automation of operation, various designs and colors, various shapes from simple to complex, small sizes, accurate product size, easy replacement of products, capability of forming products with complex shapes, suitability for the molding processing fields of mass production, products with complex shapes and the like, and the method can be used for stirring completely molten plastic materials by a screw at a certain temperature, injecting the plastic materials into a mold cavity by high pressure, cooling and solidifying to obtain molded products. The existing injection mold can only mold a single material in a single cavity of a mold base, so that the production efficiency of the mold is reduced, and meanwhile, a worker needs to repeatedly inject liquid into different mold cavities to be molded, so that the labor intensity of the worker is increased, and inconvenience is brought to the worker.

Disclosure of Invention

The utility model aims at providing an adjustable die cavity injection mold that structure setting is reasonable and the suitability is strong.

The technical scheme for realizing the purpose of the utility model is that the injection mold with the adjustable cavity comprises a lower mold seat and an upper mold seat, a cavity is arranged in the lower die base, an adjusting cavity is also arranged in the lower die base, the adjusting cavity is positioned under the cavity and is larger than the cavity, a supporting plate is arranged in the adjusting cavity, a sealing ring is arranged between the top surface of the supporting plate and the bottom wall of the cavity, a baffle plate is arranged on the supporting plate, the height of the baffle plate is the same as the depth of the cavity, clamping pieces which are bent outwards are integrally formed at the bottom ends of the symmetrical side edges of the baffle plate, a telescopic cylinder is fixed between the supporting plate and the bottom wall of the adjusting cavity, when the partition plate is arranged in the cavity, the clamping piece is arranged on the sealing ring between the bottom wall of the cavity and the supporting plate, and is pressed, positioned and fixed under the action of the telescopic cylinder.

The inner wall of the adjusting cavity is provided with a dovetail guide groove, the side face of the supporting plate is integrally formed with a dovetail guide sliding block matched with the dovetail guide groove, the dovetail guide sliding block is positioned in the dovetail guide groove, and a buffer spring is fixed between the bottom wall of the dovetail guide sliding block and the bottom wall of the dovetail sliding groove.

The baffle is a straight-line or cross-shaped plate body, and a connecting terminal and a control button which are connected with the telescopic cylinder and are used for being connected with the air pump are fixed on the lower die base.

The thickness of the clamping piece is 1/2 the thickness of the sealing ring.

The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, can change the baffle as required, and the baffle separates into several little injection molding chambeies with the die cavity, only need go up and down the backup pad when changing to fix a position or detach the screens piece through the diapire of backup pad and die cavity, use reliable and stable, and can accomplish the processing of a plurality of work pieces simultaneously, be favorable to improving the efficiency of processing, the suitability is strong and the practicality is good.

Drawings

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the following specific embodiments, taken in conjunction with the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

(example 1)

Fig. 1 shows a specific embodiment of the present invention, wherein fig. 1 is a schematic structural diagram of the present invention.

Referring to fig. 1, the injection mold with the adjustable cavity comprises a lower die holder 1 and an upper die holder 2, a cavity 3 is arranged in the lower die holder, an adjusting cavity 4 is also arranged in the lower die base, the adjusting cavity is positioned right below the die cavity and is larger than the die cavity, a supporting plate 5 is arranged in the adjusting cavity, a sealing ring 6 is arranged between the top surface of the supporting plate and the bottom wall of the cavity, a baffle plate 7 is arranged on the supporting plate, the height of the baffle plate is the same as the depth of the cavity, clamping pieces 8 which are bent outwards are integrally formed at the bottom ends of the symmetrical side edges of the baffle plate, a telescopic cylinder 9 is fixed between the supporting plate and the bottom wall of the adjusting cavity, when the partition plate is arranged in the cavity, the clamping piece is arranged on the sealing ring between the bottom wall of the cavity and the supporting plate, and is pressed, positioned and fixed under the action of the telescopic cylinder. When the sealing ring clamping device is used, the clamping piece can compress the clamping position of the sealing ring, so that the clamping piece can be fixed, and the sealing performance can be realized.
