Abstract
The utility model provides a velocity of flow adjustable injection mold, relates to the technical field that moulds plastics, and that solves improves the forming stability of product and product quality's technical problem. This mould includes the template, seted up the type of moulding plastics groove in the template, the type of should moulding plastics groove has a plurality of injecting glue runners, its characterized in that: still include a plurality of throttle posts, the throttle post is from last to down being divided into two shell of columns, and the external diameter of shell of column under the external diameter of shell of column is greater than it on, and each post of reducing expenditure is laid on each injecting glue runner with the fits that moves about respectively, has offered the regulation hole on each injecting glue runner respectively, and the last shell of column of each post of reducing expenditure lies in each injecting glue runner respectively, and the lower shell of column of each post of reducing expenditure is respectively with the regulation hole on each injecting glue runner of screw fits connection. The utility model provides a mould is applicable to the multiple spot and advances to glue the mode of moulding plastics.
Description
Technical field
The utility model relates to injection molding technology, particularly relates to the technology of the adjustable injection mold of a kind of flow velocity.
Background technology
Producing larger moulding all adopts multiple spot to enter glue mode usually, and when adopting which to carry out injection moulding, its injection moulding is filled type and all regulated by cast gate size and cast gate quantity.But the product that multiple spot enters glue is all larger; the mode regulated by cast gate size and cast gate quantity is difficult to accomplish die cavity to be full of within the regular hour simultaneously; thus cause the forming stability of product and product quality all lower, easily cause product appearance to occur vestige or other the flaw of obvious cast gate.
Utility model content
For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model be to provide a kind of can improve product forming stability and the adjustable injection mold of the flow velocity of product quality.
In order to solve the problems of the technologies described above, the injection mold that a kind of flow velocity provided by the utility model is adjustable, comprises template, described template offers injection molding groove, and this injection molding groove has multiple injecting glue runner, it is characterized in that: also comprise multiple throttling pillar;
Described throttling pillar is divided into two shell of columns from top to bottom, and external diameter of shell of column is greater than the external diameter of lower shell of column on it, each throttling pillar is laid on each injecting glue runner with movable fit system respectively, each injecting glue runner offers adjustment hole respectively, the upper shell of column of each throttling pillar lays respectively in each injecting glue runner, and the lower shell of column of each throttling pillar connects the adjustment hole on each injecting glue runner with thread fiting mode respectively.
The injection mold that the flow velocity that the utility model provides is adjustable, throttling pillar can be utilized to regulate the plastic solution flow velocity in each injecting glue runner, and the orifice size of throttling pillar is by threaded adjusting, have the advantages that velocity of flow adjust precision is high, plastic solution can be full of in each region of basic guarantee injection molding groove simultaneously, forming stability and the product quality of product can be improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adjustable injection mold of the flow velocity of the utility model embodiment;
Fig. 2 is the connection diagram of throttling pillar in the adjustable injection mold of the flow velocity of the utility model embodiment and injecting glue runner.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and embodiment of the present utility model is described in further detail; but the present embodiment is not limited to the utility model; every employing analog structure of the present utility model and similar change thereof; protection domain of the present utility model all should be listed in, the pause mark in the utility model all represent and relation.
As Figure 1-Figure 2, the injection mold that a kind of flow velocity that the utility model embodiment provides is adjustable, comprises template 1, and described template 1 offers injection molding groove, and this injection molding groove has multiple injecting glue runner 2, it is characterized in that: also comprise multiple throttling pillar 3;
Described throttling pillar 3 is divided into two shell of columns from top to bottom, and external diameter of shell of column 31 is greater than the external diameter of lower shell of column 32 on it, each throttling pillar 3 is laid on each injecting glue runner 2 with movable fit system respectively, each injecting glue runner offers adjustment hole 21 respectively, the upper shell of column 31 of each throttling pillar lays respectively in each injecting glue runner 2, and the lower shell of column 32 of each throttling pillar connects the adjustment hole 21 on each injecting glue runner with thread fiting mode respectively.
The operation principle of the utility model embodiment is as follows:
Rotate each throttling pillar, the rise and fall in injecting glue runner of each throttling pillar can be controlled, when throttling pillar rises, space between the lower shell of column of throttling pillar and injecting glue runner inner wall increases, flow area also increases thereupon, when throttling pillar declines, space between the lower shell of column of throttling pillar and injecting glue runner inner wall reduces, flow area also reduces thereupon, by regulating each throttling pillar, can control the flow of the plastic solution in each injecting glue runner, thus to make each region of injection molding groove fill as much as possible full simultaneously.
Claims (1)
