Abstract
The invention discloses a two-plate mold with an automatically broken side gate. The two-plate mold comprises a fixed mold insert, a movable mold insert, a movable mold B plate, a plastic piece push rod, a push rod fixed plate, a push rod baseplate and a mold baseplate, and further comprises a runner push rod and a delay pin, wherein the front part of the runner push rod penetrates through the movable mold insert and the movable mold B plate, and the tail end of the runner push rod is clamped in the push rod fixed plate; a groove is formed in the push rod baseplate; the delay pin is arranged in the groove, and is provided with a gap in the groove; and the front end of the delay pin is connected with the tail end of the runner push rod. According to the two-plate mold with the automatically broken side gate provided by the invention, a condensed material of a gating system of the two-plate mold can be automatically separated from a plastic piece through the design of the runner push rod and the delay pin so as to prevent the workload of manual gate cutting after the mold release.
Description
Technical field
The present invention relates to a kind of side gate from dynamic circuit breaker cast gate two plate moulds, belong to injection mold technical field.
Background technology
At present, the solidifying material of the running gate system of existing three template dies can Automatic-falling, and the solidifying material of running gate system of two template dies, except sub marine gate, is synchronously ejected by push rod conventionally together with plastic, after the demoulding, again by manually excising cast gate, so can increase a lot of workloads.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of side gate from dynamic circuit breaker cast gate two plate moulds.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of side gate is from dynamic circuit breaker cast gate two plate moulds, comprise cover half mold insert, dynamic model mold insert, dynamic model B plate, plastic push rod, ejector pin retaining plate, push rod base plate, die bottom plate, also comprise runner push rod, time delay pin, described runner push rod front portion is through dynamic model mold insert, dynamic model B plate, and runner push rod end is connected in ejector pin retaining plate; In described push rod base plate, be provided with groove, in groove, be provided with time delay pin; Described time delay pin is provided with space in groove; Described time delay pin front end is connected with runner push rod end.
Described time delay pin comprises front end base, rear end pillar.
Described gap length is set to T, represents the stroke that time delay pin moves forward and backward.
In described dynamic model mold insert, be provided with overhead structure.
As preferred version, described gap length T is set to 5mm-6mm.
As preferred version, described time delay pin front end base diameter is greater than runner putting back-end base diameter.
Beneficial effect: side gate provided by the invention is from dynamic circuit breaker cast gate two plate moulds, and by the design of runner push rod, time delay pin, the solidifying material of the running gate system of two template dies also can be accomplished automatically separated with plastic, thereby has avoided manually excising cast gate workload after demoulding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of side gate is from dynamic circuit breaker cast gate two plate moulds, comprise cover half mold insert 1, dynamic model mold insert 2, dynamic model B plate 3, plastic push rod 4, ejector pin retaining plate 5, push rod base plate 6, die bottom plate 7, also comprise runner push rod 8, time delay pin 9, described runner push rod 8 front portions are through dynamic model mold insert 2, dynamic model B plate 3, and runner push rod 8 ends are connected in ejector pin retaining plate 5; In described push rod base plate 6, be provided with groove 10, in groove 10, be provided with time delay pin 9; Described time delay pin 9 is provided with space in groove 10; Described time delay pin 9 front ends are connected with runner push rod 8 ends.
Described time delay pin 9 comprises front end base, rear end pillar.
Described gap length is set to T, represents the stroke that time delay pin 9 moves forward and backward.
In described dynamic model mold insert 2, be provided with overhead structure 11.
As preferred version, described gap length T is set to 5mm-6mm.
As preferred version, described time delay pin 9 front end base diameters are greater than runner push rod 8 rear end base diameters.
Specific embodiment is as follows: adopt runner push rod 8, make in plastic, to eject after the solidifying material of runner, i.e. time delay ejects.After die sinking, plastic push rod 4 first ejects plastic, and after release T stroke, runner push rod 8 ejects the solidifying material of running gate system again, so just can accomplish that cast gate and plastic cut off automatically.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
