Abstract

The utility model discloses a cold-runner rubber injection mould structure, which comprises an upper mould plate. A runner plate, a cooling unit, a heat partition and a cavity plate are sequentially arranged below the upper mould plate, a main runner is horizontally arranged in the runner plate, branch runners are formed at two ends of the main runner, and branch sprues are formed at two ends of each branch runner. By means of the two-deck distribution of the runners, distances of entry of rubber into the cavities are shorter, inlet speed balance of the rubber entering the runners is guaranteed, injection moulding of rubber products in the cavities are completed simultaneously, the best effect is achieved, raw materials and energy sources are saved while high yield and high quality of products are guaranteed, cost is reduced, and production efficiency is improved.

Description

A kind of cold runner rubber ejection shaping die structure
Technical field
The utility model relates to the rubber ejection shaping die, is specifically related to a kind of double-deck cold runner structure rubber ejection shaping die structure.
Background technology
Rubber not only provides daily life indispensable light industry rubber product such as daily, medical for people, and is widely used in heavy industry such as digging, traffic, building, machinery, electronics and new industry because of its excellent specific property.At present, make rubber product and mainly adopt dual mode, a kind of is the hot flow path injection mode that adopts common plastic rubber shaping commonly used, and another kind is to adopt the cold runner injection system.Though the cold runner injection system improves to some extent on technology, but in the multi-imprssion mould tool, because of being subjected to the influence of runner length, it is unbalanced to advance glue speed, and non-uniform temperature in the die cavity has had a strong impact on product quality stability, according to the conventional method, be difficult to control, in actual production process, often need debugging for a long time, reduced production efficiency.
The utility model content
The utility model purpose: in order to overcome the deficiencies in the prior art, a kind of cold runner rubber ejection shaping die structure that the utility model proposes solves many types of chamber and advances the unbalanced problem of glue speed.
Technical scheme: for solving the problems of the technologies described above, this mould comprises cope match-plate pattern, be provided with runner plate down successively at it, cooling unit, thermal insulation board and cavity plate are advanced cast gate and are located on the cope match-plate pattern, and level is provided with sprue in described runner plate, become runner in its two ends branch shape, runner two ends branch forms cast gate.
Sprue and runner connect and compose path by vertical runner.
Beneficial effect: compared with prior art, this mould structure is by the distribution of above-mentioned two-layer runner, make sizing material enter the runner of each die cavity apart from more approaching, guaranteed to advance the glue velocity balance in each runner, the rubber ejection formation in the die cavity is finished synchronously, reached optimum efficiency, guaranteeing product high yield, high-quality while, also save the raw material and the energy, reduced cost, improved production efficiency.
Description of drawings
Fig. 1 is the bright structure vertical view of the utility model;
Fig. 2 is the utility model section of structure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1 and Figure 2, this mould structure is the cold runner rubber ejection shaping die at a place six, and it comprises cope match-plate pattern 1, is provided with runner plate 2 successively down at it, cooling unit 3, and thermal insulation board 4 and cavity plate 5, glue-feeder 6 is located on the cope match-plate pattern 1.Level is provided with sprue 7 in described runner plate 2, become runner 8 from the downward branch shape in its two ends, sprue 7 and runner 8 connect and compose path by vertical runner 10, form the cast gate 9 that communicates with six die cavities from vertical runner 10 with mind-set runner 8 two ends branches runner 8 junctions are.
During work, sizing material injects from glue-feeder 6, flows in the sprue 7 of ground floor, and the vertical runner 10 through sprue 7 both sides enters in the runner 8 of the second layer again, enters cast gate 9 through runner 8 branches at last and flows into then in six die cavities.Thus, by double-layer channel is set, make the runner that enters each die cavity apart from keeping approaching, guaranteed that each die cavity advances the glue velocity balance, the rubber ejection formation in the die cavity is finished synchronously, the rubber product of ejection formation is guaranteeing its high yield, high-quality while, robber materials and energy resource consumption have also been saved greatly, provide cost savings, reduced labor strength, production efficiency is further improved.
The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
