Abstract
The utility model discloses an anti-breaking runner structure. The runner structure comprises a main runner and sub runners which are communicated with the main runner, wherein glue inlets are respectively formed in the two ends of the sub runners; a connection bridge is formed on each sub runner and plays a role of a reinforcing rib; and the two ends of the connection bridges are respectively arranged on the upper end faces of the sub runners on the left and right ends of the main runner. The connection bridges which play the role of the reinforcing ribs are arranged on the sub runners and close to the glue inlets, the glue inlets can still be brought out from waste materials under the action of the connection bridges which are served as the reinforcing ribs even if the middle positions of the sub runners are broken in a demoulding process, and the quality of an integral injection-moulded part cannot be influenced.
Description
Technical field
The utility model relates to a kind of mold injection running gate system, relates in particular to the flow passage structure that preventing in a kind of mold injection running gate system fractures.
Background technology
In the design of the cast gate of mould, technology commonly used has side type to advance to water and submarine advances to water two kinds, wherein side type advance to water into general, use history more of a specified duration; Sub marine gate is located at the one-sided of dynamic model or cover half usually, and it can be placed in inner surface or the shelter, side of plastic, also can be placed on the muscle, post of plastic, also can be placed on the die joint.Sub marine gate is generally the bullet shape, and has a certain degree with die cavity, often be 30 degree to 55 degree, the advantage of sub marine gate is as follows: 1, the charging cast gate is general all in inner surface or the shelter, side of plastic, does not influence products appearance; 2, behind the product molding, when ejecting can with the plastic automatic breaking, be easy to realize the production automation; 3, because sub marine gate can be arranged on muscle that product surface can not see, the post, can not stay owing to spray the gentle line of spray trace that brings at product surface during moulding.Owing to can directly finished product model and runner model be disconnected when submarine advances to water depanning, reduce the time of cutting cast gate, secondary operations, so sub marine gate be a kind of structure that is in daily use.
As shown in Figure 1, traditional flow passage structure is, solation through sprue 2 to runner 3, again by the injection mo(u)lding to the moulding 5 of die cavity of the glue-feeder 4 of runner 3.When moulding when needing the demoulding, because glue-feeder is sideling, so arch upward (pushing up from the bottom up in the time of the demoulding) that runner can be pushed up by thimble in the demoulding, if elastic properties of materials is better, be no problem, but present situation have a lot of materials more crisp, when ejecting distortion, can rupture, to cause that section of glue-feeder waste material can't the demoulding after causing runner to disconnect, cause mold die, can't automated production.
The utility model content
The technical problems to be solved in the utility model is to prevent the flow passage structure that fractures in order to overcome technological deficiency recited above, to provide.
In order to solve technical problem recited above, the utility model is taked following technical scheme:
A kind of flow passage structure of fractureing of preventing, the runner that includes sprue and be communicated with sprue, the two ends of described runner have glue-feeder, described runner has been provided with the connection bridge of reinforcement effect, and the two ends of described connection bridge are arranged at the runner upper surface at the two ends, the left and right sides of sprue respectively.
Connect bridge and adopt thinner glue position design, elasticity is preferably arranged, owing to be arranged in the both sides of runner, rupture even runner has been subjected to bigger bending, the bending that connects bridge also can be less.
Described connection bridge is for connecting the bridge group, and described connection bridge group is positioned at the same side of sprue, and the two ends of described connection bridge group are arranged at the runner upper surface at the two ends, the left and right sides of sprue respectively.
Described connection bridge group further includes the first connection bridge group and is connected the bridge group with second, and described first connects the front side that the bridge group is positioned at sprue, and first two ends that connect the bridge group are arranged at the runner upper surface at the two ends, the left and right sides of sprue respectively; Described second connects the rear side that the bridge group is positioned at sprue, and second two ends that connect the bridge group are arranged at the runner upper surface at the two ends, the left and right sides of sprue respectively.
A kind of flow passage structure that the runner that fractures can be pulled out of the utility model, by the connection bridge of reinforcement effect has been set in the position at the close glue-feeder of runner, even the runner centre position has disconnected during the demoulding like this, owing to connect the effect that bridge has played reinforcement, therefore still glue-feeder can be brought out from waste material, and not influence the quality of whole moulding.

The specific embodiment
Embodiment one:
See also Fig. 2, as shown in the figure, a kind of flow passage structure of fractureing of preventing, the runner 3 that includes sprue 2 and be communicated with sprue 2, the two ends of runner 3 have glue-feeder 4, glue-feeder 4 enters in the moulding 5 of die cavity, and runner 3 has been provided with the connection bridge 6 of reinforcement effect, and the two ends that connect bridge 6 are arranged at runner 3 upper surfaces at the two ends, the left and right sides of sprue 2 respectively.Connecting bridge adopts thinner material softer and that elasticity is stronger to make.Connect bridge 6 for connecting the bridge group, connect the same side that the bridge group is positioned at sprue 2, the two ends that connect the bridge group are arranged at runner 3 upper surfaces at the two ends, the left and right sides of sprue 2 respectively.
Embodiment two:
A kind of flow passage structure of fractureing of preventing, the runner 3 that includes sprue 2 and be communicated with sprue 2, the two ends of runner 3 have glue-feeder 4, glue-feeder 4 enters in the moulding 5 of die cavity, runner 3 has been provided with the connection bridge 6 of reinforcement effect, and the two ends that connect bridge 6 are arranged at runner 3 upper surfaces at the two ends, the left and right sides of sprue 2 respectively.Connecting bridge adopts thinner material softer and that elasticity is stronger to make.Connect bridge 6 for connecting the bridge group, connecting the bridge group further includes first and connects bridge group 61 and be connected bridge group 62 with second, first connects the front side that bridge group 61 is positioned at sprue, and first two ends that connect bridge group 61 are arranged at runner 3 upper surfaces at the two ends, the left and right sides of sprue 2 respectively; Second connects the rear side that bridge group 62 is positioned at sprue 2, and second two ends that connect bridge group 62 are arranged at runner 3 upper surfaces at the two ends, the left and right sides of sprue 2 respectively.
