Abstract

The invention discloses a double-side feed casting mold adopting the principle of split-end horizontal quantification. The structure includes a fixed bottom plate, a lower mold, an upper mold, positioning pins, a feeding structure, and a spaced crossbeam. There are two spaced crossbeams, And it is installed on both ends of the top of the fixed bottom plate by welding, the lower mold is a rectangular structure, and the bottom is connected with the upper end of the spaced beam by fitting. When the raw material is introduced into the casting mold of the present invention, it is injected into the double-sided material cavity through two sprues. When the feeding is inconsistent, the level of the material pressure mechanism changes, and the distribution mechanism is driven to control the quantitative plate in the sprue to swing, thereby realizing automatic The rapid limit change effectively ensures the uniform introduction of raw materials into both sides of the cavity, avoiding overflow caused by too fast feeding at one end, and uniform feeding can ensure that the appearance of the two built-in split mold products is consistent, avoiding detection of subsequent finished products error.

Description

technical field

[0001] The invention relates to the field of moulds, in particular to a double-feed casting mold adopting the principle of split-end horizontal quantification. Background technique

[0002] During the processing of injection molds, the plastic is first heated and melted in the heating cylinder at the bottom of the injection machine, and then driven by the screw or plunger of the injection machine, it enters the mold cavity through the nozzle of the injection machine and the gating system of the mold, and the plastic cools and hardens. , demoulding to obtain the product. The casting process structure is usually composed of molding parts, pouring system, guide parts, ejection mechanism, temperature adjustment system, exhaust system, support parts and other parts. The mold is the main part of molding, and the injection molding processing method is usually only suitable for thermoplastic products. product production. There are such problems in the use of existi...
