Abstract
The utility model discloses a plastic injection mold for automobile signboards. The plastic injection mold comprises a locating plate, a cavity and a core, wherein the core is fixed on the locating plate through a fixing frame; the cavity and the core are fitted with each other to form a plastic injection space for the automobile signboards; the upper surface of the core is a plane; the inner side surface of the cavity comprises a primary surface and a transition surface; the primary surface is positioned above the transition surface; an acute angle is formed between the transition surface and the upper surface of the core, and is within the range of 89-89.6 degrees; an obtuse angle is formed between the primary surface and the transition surface. The plastic injection mold has the following advantages: the trimming generation is prevented to the greatest degree; specific angle selection needs to know the trimming positions of products beforehand; the cost of reopening the mold due to obvious trimming after the plastic injection of the products is largely reduced; the workload in manually finishing the product trimming is decreased; the step of repeated debugging due to trimming is saved; the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of injection mold, especially relates to a kind of injection mold of automobile logo board.
Background technology
A lot of plastic electroplating parts on automobile frame, have conventionally been decorated, as automobile logo board, yet plastic injection piece is inadequate in mould clamp force, exhaust is bad, the suitable various reasons such as inclination of movable part slide core discontinuity equalization, product edge moulding in mould, can cause the edge of product to be easy to occur overlap, this to the far-reaching phenomenon of product percent of pass.Directly cause product client not approve, development cost increase greatly.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of injection mold that the automobile logo board of overlap defect appears in product that improves.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of injection mold of automobile logo board, comprise location-plate, die cavity and core, described core is fixed on location-plate by fixed mount, it is characterized in that forming after die cavity and core coordinate the injection moulding space of an automobile logo board, the upper surface of described core is plane, the medial surface of described die cavity comprises basic side and transition face, described basic side is positioned at the top of transition face, between described transition face and the upper surface of core, be an acute angle, described acute angle scope is 89 degree～89.6 degree, between described basic side and transition face, be an obtuse angle.
The length of described transition face and the Length Ratio of basic side are 1:10～1:20.
On described core, be provided with a plurality of thimble parts that automobile logo board after moulding is ejected.
The side of core is provided with slide block, between described slide block and described core, is provided with into glue passage.
The length in described injection moulding space is 2.5cm.
Compared with prior art, the medial surface that the utility model has the advantages that described die cavity comprises basic side and transition face, basic side is positioned at the top of transition face, between transition face and the upper surface of core, be an acute angle, acute angle scope is 89 degree～89.6 degree, between basic side and transition face, be an obtuse angle, can farthest prevent that overlap from producing, concrete angle Selection need to be known the flash locations that of product in advance; After greatly reducing product injection moulding, run the too obviously expenses such as mould reopening that produce of overlap; Reduced the workload that workman repaiies product overlap.Reduce the step of doing debugging repeatedly because running overlap, accelerated production efficiency.
