Multi-part combined plastic mold

Abstract

The invention discloses a multi-part combined type plastic mold. The multi-part combined type plastic mold comprises a pouring nozzle 1, an upper mold plate 2, a mold cavity plate 3, a stripper plate 4, a lower fixing plate 5, a base plate 6 and a mold foot 7, wherein the lower part of the pouring nozzle 1 is mounted in a central through hole of the upper mold plate 2; the mold cavity plate 3 is movably connected with the upper mold plate 2 through a hanging rod 8; the base plate 6 is fixed on the mold foot 7; the lower fixing plate 5 is fixed on the base plate 6; the multi-part combined type plastic mold is characterized in that a pin-point gate 24 is formed between the mold cavity plate 3 and the upper mold plate 2; a first convex mold 9, a second convex mold 10 and a third convex mold 11 are arranged on the lower fixing plate 5; the three convex molds respectively penetrate through a through hole of the stripper plate 4 to be movably nested with the stripper plate 4; cavities, which are matched with the first convex mold 9, the second convex mold 10 and the third convex mold 11, are formed in the end of the mold cavity plate 3, far from the upper mold plate 2. Through the mold, the pouring gate wastes are conveniently cleaned, and plastic parts are attractive in appearance; three convex molds are capable of simultaneously producing a plurality of parts, thus saving the human and material resources and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a multi-component combined plastic mould. Background technique [0002] Plug-in strips are a necessity in daily life, and various plug-in strips bring a lot of convenience to people's life and work. Many parts on the plug-in strip are processed and formed by plastic molds. In the prior art, the plastic mold for producing the parts at the power switch on the plug-in strip is a set of molds to produce one part when producing buttons, upper gear teeth and lower gear teeth. , the mold used is a sprue, but it is inconvenient to remove the gate waste during the production of the sprue, and there are obvious gate traces on the plastic part, which affects the appearance of the plastic part. These three parts of the gear and the lower gear are produced by using separate molds, which requires a large number of molds and manpower, high cost and low production efficiency.
