Abstract

A kind of injection molding, it comprises cope match-plate pattern and lower bolster, described cope match-plate pattern has additional the runner plate that a piece is processed with oil-returning structure and runner, between this runner plate and cope match-plate pattern, be furnished with the thermal insulation board they separated, between described upper and lower template, be formed with die cavity; Described cope match-plate pattern is also processed with the heating pore that can directly be connected with vulcanizer upper plate heater circuit; Described runner plate bottom is provided with glue filling nozzle, the runner that the runner that runner plate is processed comprises the sprue on upper surface and communicates with glue filling nozzle, and the oil-returning structure on runner plate is formed primarily of temperature-sensitive oil return line; Described runner plate is also provided with the installing hole for the temperature probe be connected with external temperature control device; It is simple that it has structure, uses easy to operate, save material, enhance productivity, and reduces the features such as energy consumption.

Description

A kind of injection molding
Technical field
The utility model relates to a kind of improvement mould of normal injection mould, especially a kind of can save sizing material, increase work efficiency, the injection molding of controllable flow channel temp.
Background technology
For product design dimension precision requirement or the high product of inserts shape requirement itself, if use common compression molding technology can cause the situation that cannot meet customer requirement, therefore generally adopt injection moulding hot flow path technique.If publication number is the Chinese invention patent application of CN102922682A, disclose one and comprise cope match-plate pattern, " the normal injection mould " of lower bolster, die cavity is formed between described cope match-plate pattern and lower bolster, runner leads to described die cavity, the porch of described runner comprises whole mould and is placed among vulcanizing press, realized the whole mold heated comprising sizing material in runner by heating of vulcanizer upper and lower plates, during due to this technique sulfuration, in runner, sizing material is heated sulfuration together with the goods in die cavity, the significant wastage of material can be caused, as adopted rare or valuable material as fluorubber, during poly-propionic acid fat, cost then can be made higher, cannot meet the needs of production.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of structure simple, uses easy to operate, saves material, enhance productivity, reduce the modified injection molding of energy consumption.
The purpose of this utility model has been come by following technical solution, a kind of injection molding, it comprises cope match-plate pattern and lower bolster, described cope match-plate pattern has additional the runner plate that a piece is processed with oil-returning structure and runner, be furnished with the thermal insulation board they separated between this runner plate and cope match-plate pattern, between described upper and lower template, be formed with die cavity; Described cope match-plate pattern is also processed with the heating pore that can directly be connected with vulcanizer upper plate heater circuit.
As preferably: described runner plate bottom is provided with glue filling nozzle, the runner that the runner that runner plate is processed comprises the sprue on upper surface and communicates with glue filling nozzle, and the oil-returning structure on runner plate is formed primarily of temperature-sensitive oil return line.
As preferably: described runner plate is also provided with the installing hole for the temperature probe be connected with external temperature control device.
The utility model is mainly to solve the sulfuration of heating together with product of sizing material in existing hot runner mould runner and causes the technical problem of waste of material; Provide a kind of saving sizing material, control accurate modified injection molding.
The beneficial effects of the utility model are: first carry out heat insulation to runner plate and cavity plate, ensure that sulfuration performs temperature and can not be passed on runner plate, glue filling nozzle sprue periphery design processing return line and to pour into when temperature-sensitive oil reaches the mobility that the sizing material ensured in runner keeps good and not play the object of vulcanization reaction, upper impression plate heats separately, lower impressions plate still adopts former vulcanizer to heat, temperature controls accurately with quick, energy consumption is lower, production efficiency is high, can original mould be utilized simultaneously, and not make large amendment.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Label in figure is: 1. runner plate, 2. thermal insulation board, 3. upper impression plate, 4. lower impressions plate, 5. die cavity, 6. glue filling nozzle, 7. sprue, 8. runner, 9. electric heating tube, 10. temperature-sensitive oil circuit, 11. temperature probes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of injection molding described in the utility model, it comprises cope match-plate pattern and lower bolster, described cope match-plate pattern 3 has additional the runner plate 1 that a piece is processed with oil-returning structure and runner, be furnished with the thermal insulation board 2 they separated between this runner plate 1 and cope match-plate pattern 3, between described upper and lower template 3,4, be formed with die cavity 5; Described cope match-plate pattern 3 is also processed with the heating pore 9 that can directly be connected with vulcanizer upper plate heater circuit.
Shown in figure, runner plate 1 bottom described in the utility model is provided with glue filling nozzle 6, the runner 8 that on runner plate 1, the runner of processing comprises the sprue 7 on upper surface and communicates with glue filling nozzle 6, the oil-returning structure on runner plate 1 is formed primarily of temperature-sensitive oil return line 10.
Runner plate 1 described in the utility model is also provided with the installing hole 11 for the temperature probe be connected with external temperature control device.
During use, the shaping sizing material completed injects the runner on runner plate by injector gum-injecting port, under runner on runner plate guides and distributes, sizing material evenly flow to glue filling nozzle and injects in die cavity by cast gate, now upper and lower cavity plate is each via vulcanizer baking, due to the thermal insulation board effect between upper impression plate and runner plate, sulfuration heat can not conduct in runner plate, simultaneously, the sizing material temperature in whole runner is controlled by temperature control external equipment, make the sizing material in runner and nozzle shift to an earlier date sulfuration and keep good mobility, the whole course of work can continuous glue injection and do not need gel resin, raw material are saved, improve production efficiency.
More than illustrate and not restriction has been done to the utility model; the utility model is also not limited only to the citing of above-mentioned explanation; the change that those skilled in the art make in essential scope of the present utility model, retrofit, increase or replace, all should be considered as protection domain of the present utility model.
