Problems solved by technology

[0003] When aluminum profile molds are used for injection molding, it is necessary to match the upper and lower templates together, but the current matching method does not have a good sealing effect, so there is still a lot of air near the cavity, which will enter during the raw material molding process. into the raw material, thereby forming air bubbles, seriously affecting the quality of molded parts

Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] see Figure 1-3 As shown, a vacuum-type aluminum profile mold includes an upper template 1; an upper cavity 11 is opened at the center of the bottom of the upper template 1, and mounting columns 13 are distributed on both sides of the upper cavity 11; The mounting column 13 is vertically fixed to the bottom surface of the upper formwork 1, and the side wall of the upper formwork 1 has a limit groove 12; the outer wall of the upper formwork 1 is rotatabl...

Abstract

The invention discloses a vacuum type aluminum profile mould. The vacuum type aluminum profile mould comprises an upper mould plate, an upper mould cavity, a limiting groove, mounting columns, an outer rotation disc, handles, a fixing sleeve, a limiting head, a lower mould plate, a lower mould cavity, suction openings, mounting holes, a fixing groove, push rods, first rubber plates, connection rods, suction mechanisms, suction one-way valves, suction pipes and second rubber plates. An air blower of the mould provided by the invention can continue being screwed downwards after the mounting columns and the mounting holes are matched so that the fixing sleeve can be closely matched in the fixing groove, thus, the connection strength between the upper mould plate and the lower mould plate is effectively improved, the sealing effect is improved, and the moulding effect influenced by entry of outside air is avoided; in the process of screwing the fixing sleeve downwards, the rubber plates can be driven to move downwards, so that air around the mould cavities are sucked out to enable the mould cavities to be in vacuum environments, thus, the quality of a formed piece is improved; and theair one-way valves are additionally arranged, which can prevent backflow of the sucked air.

Description

technical field [0001] The invention relates to an aluminum profile mold, in particular to a vacuum-type aluminum profile mold, which belongs to the technical field of mold equipment applications. Background technique [0002] Aluminum profile mold has excellent thermal conductivity, and its thermal conductivity is higher than that of general mold steel, so it can save the cold cutting time of the mold during production, thereby improving the production efficiency of the mold. It is widely used in different mold industries; with the development of the market, super duralumin has replaced steel as the mainstream mold. [0003] When aluminum profile molds are used for injection molding, it is necessary to match the upper and lower templates together, but the current matching method does not have a good sealing effect, so there is still a lot of air near the cavity, which will enter during the raw material molding process. Into the raw material, thereby forming air bubbles, se...
