Abstract
The invention discloses an injection molding machine for an unsaturated polyester bulk molding compound and belongs to the technical field of mechanical device manufacture. The injection molding machine comprises a machine frame, an injection seat installed on the machine frame, a machine barrel installed on the injection seat and provided with a screw inside, a material storing cylinder arranged above a feeding inlet of the machine barrel and a heating device. The upper end of the material storing cylinder is communicated with a material pressing cylinder body with vertically-arranged axis, and a material pressing piston connected with a piston rod of a material pressing drive oil cylinder is arranged in the material pressing cylinder body. One side of the material pressing cylinder body is communicated with a feeding tank provided with a feeding port at the upper portion, and a material pushing plate connected with the piston rod of the material pressing drive oil cylinder is arranged in the feeding tank. The injection molding machine for the unsaturated polyester bulk molding compound can solve the problems that the feeding amount is difficult to balance, and the labor intensity is large.
Description
Technical field
The present invention relates to plant equipment manufacturing technology field, especially a kind of plastic injection-moulded machinery.
Background technology
BMC also claims the unsaturated polyester BMC.Its primary raw material is by short glass fiber, unsaturated-resin, filler and the various additive bulk material through fully mixing; This raw material has good electrical insulation properties, mechanical performance, heat resistance, chemical resistance can adapt to various moulding process again, from the sixties in 20th century from Europe, electronics industry and household electrical appliance have been widely used in, auto manufacturing and motor component etc.And existing general injection molding machine of plastic is only applicable to the product of production feed particulate material, the Shooting Technique process of its melten gel plasticizing be with granular raw material manually weighing be added into mould from feeding funnel, and hot briquetting.Thereby the product of producing the BMC raw material now adopts is unsaturated polyester BMC injection machine; But in existing unsaturated polyester BMC product injection molding process, since raw material be shaped as bulk, when adding raw material, raw material one need to be dropped into round and round the feed hopper above the machine barrel, sometimes also need to enrich by hand operation, inventory is difficult to equilibrium, and labour intensity is large.
Summary of the invention
Technical problem to be solved by this invention provides a kind of unsaturated polyester smectic moulding compound injection machine, and it can solve unsaturated polyester smectic moulding compound injection machine inventory and be difficult to equilibrium, the problem that labour intensity is large.
In order to address the above problem, technical scheme of the present invention is: this unsaturated polyester smectic moulding compound injection machine, include frame, be installed in the injection seat on the described frame, the machine barrel of screw rod is housed in being installed on the described injection seat, and what be arranged on described machine barrel feed entrance top holds material cylinder and heater, be communicated with the binder cylinder body that an axis is erect setting in the described material cylinder upper end of holding, a binder piston that is connected with the piston rod of binder driving oil cylinder is arranged in this binder cylinder body; One side of described binder cylinder body is communicated with the feeding trough that a top is provided with the described spout of dog-house by a spout, has one to connect the scraping wings that feeding drives the piston rod of oil cylinder in this feeding trough.
In the technique scheme, more specifically scheme can also be: described binder piston is connected with a stroke limit bar, in the stroke of the collision block on the trip gag lever post travel switch is housed.
Further: in the bottom over against described feeding trough dog-house the feeding trough lower cover is installed.
Because adopt technique scheme, the present invention has following beneficial effect:
The present invention increases feeding mechanism, make machine can add proper material lays in holding the material cylinder at every turn, need not artificial one feeding intake round and round, inventory is relatively more balanced, be convenient to the one man operation, feeding mechanism has strengthened convenience and operability by electrical equipment control simultaneously, enhances productivity, and has reduced labour intensity.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is feeding mechanism schematic diagram among the present invention.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Unsaturated polyester BMC injection machine illustrated in figures 1 and 2 includes frame 1, is installed in the injection seat 2 on the frame 1, and the machine barrel 3 of screw rod is housed on the injection seat 2 that is installed in, and what be arranged on machine barrel 3 feed entrances top holds material cylinder 4 and heater 5; Be communicated with an axis and erect the binder cylinder body 6-1 that arranges holding material cylinder 4 upper ends, a binder piston 6-2-3 who is connected with the piston rod of binder driving oil cylinder 6-2 is arranged in this binder cylinder body 6-1; The side of binder cylinder body 6-1 is communicated with the feeding trough 6-3-1 that a top is provided with the described spout of dog-house by a spout, has one to connect the scraping wings 6-3-4 that feeding driving oil is taken out the piston rod of cylinder 6-3 in this feeding trough 6-3-1.
Binder piston 6-2-3 is connected with a stroke limit bar 6-2-4, and up and down two travel switch 6-2-5 are housed in the stroke of the collision block on the trip gag lever post 6-2-4; These two travel switches are connected on the controller of the machine, the position of the upper collision block of adjustment stroke gag lever post 6-2-4, can regulate the position of the degree of depth of the downward binder of binder piston 6-2-3 and the return that makes progress, in stroke limit bar 6-2-4 motion process, drive collision block and travel switch collision, make the travel switch closure or openness that connect controller, thus the position that control binder piston 6-2-3 stops or starting.
In the bottom over against described feeding trough 6-3-1 dog-house feeding trough lower cover 6-3-5 is installed, is convenient to when reloading clearing up and keep in repair in the feeding trough 6-3-1.
