Abstract
The utility model belongs to a mould, which particularly relates to a rubber piece injecting mould. A three-way connecting piece multi-cavity injecting mould comprises an upper mould and a lower mould, wherein the interior of injecting mould is provided with an upper mould core, a middle mould core and a lower mould core, and the three mould cores are communicated with each other; the axis directions of the upper mould core and the lower mould core are parallel, and the directions of the openings are opposite; the included angle between the middle mould core, the upper mould core and the lower mould core is 30-60 degrees; the upper mould, two middle moulds and the lower mould are sequentially arranged along the axis directions of the upper mould core and the lower mould core; the upper mould is fixed with the upper mould core, and the lower mould is fixed with the lower mould core; and the parting surfaces of the moulds are parted along the axis curves of the upper mould core and the lower mould core. The mould structure is simplified, the operation is convenient, the vulcanizing efficiency is enhanced, and the utilization rate of the equipment and the yield of the rubber product are enhanced. Simultaneously, the injecting mould avoids the problems that the airtightness of the product is poor, the product is easy to generate abnormal cracks and the like caused by the poor rubber welding.
Description
Technical field
The utility model belongs to a kind of mould, especially a kind of rubber parts injection molding.
Background technology
At present, the mould structure of household electrical appliance rubber parts commonly used mostly is two cavity moulds, and as shown in Figure 1, mould adopts vertical symmetry straight line somatotype, has six movable core rods in two chambeies, and movable core rod is more, so product sulfuration charge and discharge operations complexity; Secondly, adopt two cavity moulds to be difficult to increase mold cavity, influenced the utilization rate of vulcanization of rubber efficient and die apparatus greatly, restricted the raising of the output and the production efficiency of product to a certain extent; In addition, the product of two cavity mould productions occurs rubber easily and welds badly, causes the poor air-tightness of product or unusual breach occurs.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective that existing rubber parts two cavity moulds exist, and has proposed a kind of three-limb tube multi-cavity injection molding.
The utility model is to adopt following technical scheme to realize: a kind of three-limb tube multi-cavity injection molding, comprise upper die and lower die, wherein, be provided with the upper strata core rod in the described injection molding, middle level core rod and lower floor's core rod, be interconnected between three core rods, the upper strata core rod is parallel with the axis direction of lower floor's core rod, opening direction is opposite, middle level core rod and upper strata, angle between lower floor's core rod is 30-60 °, is provided with patrix successively along the axis direction of the upper and lower core rod, two middle moulds and counterdie, wherein patrix is fixed with the upper strata core rod, counterdie is fixed with lower floor's core rod, and the mould die joint is along the axis curve somatotype of the upper and lower core rod.
In the utility model, because two core rods wherein are separately positioned on the upper die and lower die, behind the mold open, the upper strata core rod is along with patrix separates automatically, middle the upper and lower two-layer of mould will be separated from each other along with the rising of patrix, mould separates with counterdie simultaneously, because lower floor's core rod is fixed on the counterdie, this moment, upper and lower two core rods all separated with rubber parts fully.Compared with prior art, saved the complex operations of loading and unloading a plurality of core rods.Therefore, only need rubber parts to be taken out from mould along upset middle level core rod.
The beneficial effects of the utility model are: this injection molding is adjusted mould structure, and is easy to operate, when improving sulfuration efficient, also improved the output of usage ratio of equipment and rubber product; Simultaneously, adopt injection molding avoided since rubber weld the bad products air tightness that causes poor, problem such as unusual breach appears easily.
Description of drawings
Fig. 1 is the structural representation of rubber parts two cavity moulds;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 2, be provided with three the upper strata core rods 2 that are interconnected, middle level core rod 5 and lower floor's core rods 6 in this three-limb tube multi-cavity injection molding, its at the middle and upper levels the axis of core rod 2 and lower floor's core rod 6 be parallel to each other, but the opening direction of two core rods is opposite, and the angle between middle level core rod 5 and the lower floor's core rod 6 is 57 °.Axis direction along upper strata core rod 2 and lower floor's core rod 6 is provided with patrix 1, middle mould 3,4 and counterdie 7 successively, promptly along the axis direction curve somatotype of core rod.Its at the middle and upper levels core rod 2 be fixed on the patrix 1, lower floor's core rod 6 is fixed on the counterdie 7.This mould is an injection molding, has avoided welding of rubber bad, has improved the air-tightness of rubber parts product.Adopt the semi-automatic mould that opens during die sinking, upper strata core rod 2 is along with patrix 1 separates automatically, and middle mould 3,4 risings along with patrix are separated from each other, and mould separates with counterdie 7 in the while, because lower floor's core rod 6 is fixed on the counterdie 7, this moment, the upper and lower core rod all separated with rubber parts fully.Therefore as long as upset middle level core rod 5 can take out rubber parts from mould.Mould is opened the back only has a movable core rod in the die cavity, can produce the 8-12 chamber simultaneously when adopting symmetrical rotary structure.Therefore adopt this injection molding to improve the output of sulfuration efficient, usage ratio of equipment and product greatly; The operation of Qi Moshi has been simplified in the change of this mould inside structure simultaneously.
