Problems solved by technology
[0002] Existing injection molds for plastic sleeves, especially plastic sleeve injection molds with arc-shaped chamfers inside and outside, have a very unreasonable structure. A pair of molds can only process parts of one specification and size, but cannot process parts of different specifications. The size of the product, and the arc chamfer is often frizzy and uneven, and some parts are incomplete, resulting in poor production quality, low utilization rate of equipment, waste of resources, and high processing cost of the product

Embodiment Construction
[0010] The present invention is described below in conjunction with accompanying drawing.
[0011] attached figure 1 It is a mold for the production of a plastic sleeve according to the present invention. The plastic sleeve is a flat plastic sleeve with internal and external arc chamfers. The mold includes an upper mold 1 and a lower mold 2. The upper mold 1 and the The lower dies 5 are inserted into the positioning holes 4 through the positioning pins 6 for positioning connection, and the upper die 1 is provided with a plurality of protrusions 5 with arc chamfers of at least two specifications; The mold 2 is provided with a cavity 6 for forming a plastic sleeve with the protrusion 5; the cavity 6 is provided with an arc-shaped chamfer 7; the upper mold 1 is provided with an air outlet groove 8, and the air outlet groove 8 is located at the periphery of the bump 5 .
[0012] The above-mentioned embodiments are only to illustrate the technical conception and characteristics o...

The invention discloses a mold for producing a plastic cover. The plastic cover is in a flat shape with inner and outer arc chamfer angles; the mold comprises an upper mold and a lower mold; the upper mold and a lower mold are inserted in a location hole by a locating pin to carry out locating connection; the upper mold is provided with a plurality of lugs with at least two specifications and arc chamfer angles; the lower mold is provided with mold cavities cooperating with the lugs; the arc chamfer angles are disposed in the mold cavities; the upper mold is provided with air out tanks and the air out tanks are disposed out of the lugs. According to the mold used for producing the plastic covers, the production of high-quality and different-specification plastic covers with the inner and outer arc chamfer angles is more simply and conveniently by structural design of the mold; the utilization rate of the mold is increased; resource is saved; and production cost is reduced.
Description
technical field [0001] The invention relates to a mold, in particular to a mold for plastic sleeve production, which belongs to the technical field of mold manufacturing. Background technique [0002] Existing injection molds for plastic sleeves, especially plastic sleeve injection molds with arc-shaped chamfers inside and outside, have a very unreasonable structure. A pair of molds can only process parts of one specification and size, but cannot process parts of different specifications. The size of the product, and the arc chamfer is often rough and partially incomplete, resulting in poor production quality, low utilization rate of equipment, waste of resources, and high processing costs of the product. Contents of the invention [0003] In view of the above-mentioned technical problems, the purpose of the present invention is to propose a mold for the production of plastic sleeves suitable for making products of different specifications, which has high utilization rate ...
