Abstract
A plastic die large-span hidden type gate comprises an upper bottom plate and a lower bottom plate, wherein the upper bottom plate is connected with a model cavity, a sprue frame is mounted in the model cavity, the sprue frame is provided with a heat nozzle, a die leg and a top plate are mounted on the lower bottom plate, a model core is mounted on the die leg, a die cavity is arranged between the model core and the model cavity, a top rod is mounted on the top plate, the gate is characterized in that a straight top block is arranged in the model core, the lateral wall of the straight top block is provided with a curved sprue, one end of the curved sprue is extended to the inner surface side of a plastic product, the other end of the curved sprue is connected with the heat nozzle, and the bottom portion of the straight top block is connected with the top rod. The technical solution is that the straight top block is arranged in the model core, the lateral wall of the straight top block is provided with the curved sprue, one end of the curved sprue is extended to the inner surface side of the plastic product, the other end of the curved sprue is connected with the heat nozzle, the gate achieves the hidden type gate in the large-span arrangement, the injection molding of large-sized plastic products is sufficient and even, and one end of the curved sprue is extended to the inner surface side of the plastic product. The plastic die large-span hidden type gate has the advantages of non-traces, smoothness and beautiful appearance of external surfaces of plastic products, and satisfies demands of people.
Description
Technical field
The utility model relates to the deployment mechanism of mould of plastics large span sub marine gate, is specially adapted to the large product outer surface and does not allow to arrange the glue running channel, again should not the side advances the plastic products of glue.
Background technology
Along with people constantly increase the demand of all kinds of big plastic coverings, particularly auto industry is to the integral body maximization of the inside and outside gadget of plastics and improving constantly of appearance requirement, and traditional production mould advances the glue mode and can't meet the demands.For example: 1, adopt traditional side gate form to advance glue, because of product is bigger, remote flow losses are bigger, and product needs multiple spot advance glue, and the product center is easy to generate tired gas, lacks material, shrinks defectives such as trace is serious thus; 2, it is bigger because of the injection pressure loss to adopt traditional sub marine gate to advance the glue mode, make that product is apparent to be easy to generate shrink mark even defective such as can't to fill with, and this traditional sub marine gate is also less because of the running channel span of diving, and can't be arranged into the center of large-scale product on request; 3, adopt multiple spot point cast gate front to advance glue, can produce vestige on the product surface on the one hand; Shrink trace because of the pressure loss than surperficial easily generation of ambassador's product on the other hand, defectives such as surface irregularity, thus can't satisfy higher appearance requirement; 4, traditional cover half side ejecting structure, mould structure is comparatively complicated on the one hand, increases the Mold Making cost; Also can't make cold slug well because of this running channel on the other hand makes product surface easily produce the cold burden trace to influence the product surface quality and can't satisfy the demand.More than various traditional gate forms, can't satisfy the making requirement of big plastic covering.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provides a kind of and satisfies large span and arrange that submarine advances the glue running channel, and is simple in structure, the mould of plastics large span sub marine gate that cost is low.
The technical scheme of the utility model mould of plastics large span sub marine gate is: comprise upper plate and lower shoe, upper plate connects die cavity, the runner frame is installed in the die cavity, the runner frame has hot mouth, mould pin and top board are installed on the lower shoe, on the mould pin core is installed, constitute die cavity between core and the die cavity, push rod is installed on the top board, it is characterized in that being provided with in the described core straight jacking block, the sidewall of straight jacking block is shaped on the curve runner, and one of the curve runner extends to the plastic products inner surface side, the other end of curve runner connects hot mouth, and the bottom of straight jacking block connects push rod.
Mould of plastics large span sub marine gate of the present utility model, straight jacking block is set in described core, the sidewall of straight jacking block is shaped on the curve runner, one of the curve runner extends to the plastic products inner surface side, the other end of curve runner connects hot mouth, realized large span layout sub marine gate, make the injection moulding abundance of large scale plastic product, evenly, one of the curve runner extends to plastic products inner surface side (bottom surface of die cavity), make the plastic products outer surface not have vestige, smooth, attractive in appearance, satisfy people's demand.The bottom of straight jacking block connects push rod, and straight jacking block is ejected with goods synchronously by top board and push rod when ejecting, and the curve runner makes cold burden take out simultaneously with goods and get final product built in the sidewall of straight jacking block, and is easy to operate.
Mould of plastics large span sub marine gate of the present utility model, its described straight jacking block is more than 2 or 2, and the straight jacking block of polylith is that many curve runners advance glue, and injection moulding is even, sufficient, satisfies the injection moulding requirement of bigger plastic products.
Description of drawings
Fig. 1 is the utility model mould of plastics large span sub marine gate structural representation;
Fig. 2 is a straight jacking block schematic cross-section of the present utility model.
The specific embodiment
The utility model relates to a kind of mould of plastics large span sub marine gate, as Fig. 1, shown in Figure 2, comprise upper plate 1 and lower shoe 9, upper plate 1 connects die cavity 3, runner frame 2 is installed in the die cavity 3, the runner frame has hot mouth 21, mould pin 7 and top board 8 are installed on the lower shoe 9, core 5 is installed on the mould pin, constitute die cavity 10 between core 5 and the die cavity 3, push rod 6 is installed on the top board 8, it is characterized in that being provided with in the described core 5 straight jacking block 4, the sidewall of straight jacking block 4 is shaped on curve runner 41, and one of the curve runner extends to the plastic products inner surface side, the other end of curve runner connects hot mouth 21, and the bottom of straight jacking block 4 connects push rod 6.This programme is provided with straight jacking block 4 in described core 5, the sidewall of straight jacking block 4 is shaped on curve runner 41, one of curve runner 41 extends to the plastic products inner surface side, the other end of curve runner 41 connects hot mouth 21, has realized that large span arranges sub marine gate, makes the injection moulding abundance of large scale plastic product, evenly, one of the curve runner extends to plastic products inner surface side (bottom surface of die cavity 10), make the plastic products outer surface not have vestige, smooth, attractive in appearance, satisfy people's demand.The bottom of straight jacking block 4 connects push rod 6, and straight jacking block 4 is ejected with goods synchronously by top board 8 and push rod 6 when ejecting, and curve runner 41 makes cold burden take out simultaneously with goods and get final product built in the sidewall of straight jacking block 4, and is easy to operate.Its described straight jacking block 4 can be more than 2 or 2, and the straight jacking block of polylith is that many curve runners advance glue, and injection moulding is even, and abundance satisfies the injection moulding requirement of bigger plastic products.
