The utility model discloses the structure succinctly, rationally can realize not having the jiao kou of advancing on moulding the piece, does benefit to and improves the appearance quality who moulds the piece, reduction in production cost. The utility model discloses easily realize, can be used for saving waste artifical and that reduce production cost. Improvement and innovation for injection mold technique.
Description
Technical field
This utility model relates to plastic mould technical field, specifically a kind of sprueless molds lamps structure.
Background technology
In plastic processing industry, especially injection machine moulding process, the product that injection mold manufactures all can have a glue-feeder.The way generally used for this glue-feeder industry is: carry out cutting off glue-feeder with cutter by the plastic going out mold forming, during this, generally is carried out cutting off process by artificial or special equipment, to reach qualified plastic appearance requirement.Generally, this process can be left a trace on plastic, affects plastic outward appearance；And, it is easy to product scratch in cutting off glue-feeder processing procedure, and easily occurs that glue-feeder cuts out-of-flatness phenomenon, have a strong impact on product appearance, even result in product rejection.Cause the waste of a large amount of man power and material.
In production for the higher bakelite series products of appearance requirement, how to be reached on plastic without glue-feeder by rational mould structure, solve the glue-feeder cutting problem after depanning, and to save artificial problem of wasting with minimizing expense be industry problem to be solved.
Utility model content
The purpose of this utility model is, for above-mentioned deficiency, it is provided that a kind of simple for structure, reasonable, it is possible to realizes on plastic without glue-feeder, is beneficial to improve the presentation quality of plastic, reduces the sprueless molds lamps structure of production cost.
For achieving the above object, technical scheme provided by the utility model is: a kind of valve gated mold structure, including the close-fitting rear cavity of front cavity and front cavity, and die cavity that described front cavity includes at least two and the cast gate being located between die cavity；Described front cavity matches formation for cutting off the straight die joint that described die cavity connects with cast gate stream with rear cavity；Front cavity matches with rear cavity and is provided with at least two for sealing stream to form the straight body face of plastic die joint.
Another preferred version of the present utility model, the quantity of described die cavity is two, and two die cavities are symmetrical centered by described cast gate.
Another preferred version of the present utility model, described straight body face is two.
The beneficial effects of the utility model are: this utility model is simple for structure, reasonable, it is possible to realize on plastic without glue-feeder, be beneficial to improve the presentation quality of plastic, reduce production cost.
During injection, front cavity and rear cavity not exclusively close tight reserved one section of gap set, and make stream fill full whole die cavity, utilize straight body face to seal stream to form plastic die joint；When stream is filled to the loading preset, utilize the clamp force of injection machine itself front cavity to be locked with rear cavity high pressure, make unnecessary glue also be pushed down into the die cavity of product in melted state, so that without glue-feeder on outer surface after formed product.
Below in conjunction with the accompanying drawings with embodiment, this utility model is further illustrated.
Accompanying drawing explanation
Accompanying drawing is used to offer and is further appreciated by of the present utility model, and constitutes a part for description, is used for explaining this utility model, is not intended that restriction of the present utility model, in the accompanying drawings together with detailed description below.
Fig. 1 is the structure chart of sprueless molds of the present utility model tool, and view during injection.
Fig. 2 is mode-lock status and the plastic parts moulding schematic diagram of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is illustrated.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains this utility model, it is not limited to this utility model.
Die cavity in this utility model is for the plastic 3 of molded housing class, such as: bakelite Switch.
This utility model is injection mold, is specifically compressed into pattern, the injection machine in plastic processing machinery, it is possible to realize without glue-feeder on plastic 3, for improving the presentation quality of plastic 3；It is particularly suited for the production of bakelite series products.See Fig. 1, it is shown that structure of the present utility model is constituted.
See Fig. 1, a kind of valve gated mold structure that the present embodiment provides, including front cavity 1 and the close-fitting rear cavity of front cavity 12, die cavity that described front cavity 1 includes at least two and the cast gate 11 being located between die cavity；Described front cavity 1 matches formation for cutting off the straight die joint 4 that described die cavity connects with cast gate 11 stream with rear cavity 2；Front cavity 1 matches with rear cavity 2 and is provided with at least two for sealing stream to form the straight body face 5 of plastic 3 die joint.
Preferably, the quantity of the die cavity of the present embodiment is two, and two die cavities are symmetrical centered by described cast gate 11.
Preferably, the straight body face 5 of the present embodiment is two.
Operation principle: during injection, front cavity 1 and rear cavity 2 are not exclusively closed tight reserved one section of gap set, are made stream fill full whole die cavity；Straight body face 5 is utilized to seal stream to form plastic 3 die joint, as shown in Figure 1；When stream is filled to the loading preset, front cavity 1 is locked by the clamp force utilizing injection machine itself with rear cavity 2 high pressure, as shown in Fig. 2, unnecessary glue is made also to be pushed down into the die cavity of product in melted state, so that without glue-feeder on outer surface after formed product.
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment listed application, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, it is easily achieved other amendment, therefore, under the general concept limited without departing substantially from claim and equivalency range, this utility model does not limit specific details and shown here as the legend with description.
