Abstract
The invention provides a die cavity rotary plastic injection die, comprising an upper die cavity, a lower die cavity and a die consisting of cores; the injection die is characterized in that the bottom of the lower die cavity is arranged on a rotation mechanism; an ejector rod is arranged below the gate of the lower die cavity; the supporting plate of the lower die cavity is provided with an inclined ejector block; the inclined surface of the inclined ejector block contacts with the ejector rod. The injection die adopts die cavity rotation and needs no swing rods; an injection molding machine is corresponding to the size of the processed product. The equipment has reasonable utilization; the gate of the product is ejected by the ejector rod, thus driving the whole product to be demoulded out of the lower die cavity; the demoulding is successful and the automation is realized; a manipulator or manual operation is not needed, the labor intensity of the worker is reduced, the production efficiency is high, and the injection die is applicable for processing various arc-shaped products.
Description
Technical field
The present invention relates to injection mold, particularly relate to mold cavity rotary plastic injection mould, belong to the plastics machinery field, be mainly used in the processing of hollow arc product (working of plastics).
Background technology
Hollow arc working of plastics (for example the UT accessory in the water-drainage tube part etc.) adds the demoulding in man-hour in injection and is difficult to; Prior art adopts the rotary demoulding of circular arc core; Be that hydraulic jack is fixed on the mould bases rotating stripping demoulding of realizing the circular arc core through fork push-and-pull centering block,, therefore adopt machine to be far longer than the molding machine that this product injection volume equates because the rotation amplitude of fork is bigger in knockout course; Production of articles factory has only employing " big machined miscellaneous goods ", causes utilization rate of equipment and installations low.In addition, because the die cavity bottom is equipped with centering block and is interfered with ejector pin of die set, make mould that mould emptier can't be installed, and can only lean on manipulator or artificial the taking-up.If shrink few material with some, it is smooth to produce the demoulding, and production efficiency is low.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming that prior art exists, provide a kind of and by the rotation of power drive mold cavity the arc product is deviate from, it is low that mould is suitable for type, and equipment utilization is reasonable, automatic demoulding, the mold cavity rotary plastic injection mould that production efficiency is high.
The technical scheme of mold cavity rotary plastic injection mould of the present invention is: comprise the mould that upper and lower die cavity and core are formed; The bottom that it is characterized in that lower impressions is installed on the rotating mechanism; Push rod is installed in the cast gate below of lower impressions; On the lower impressions support plate, slanted kicking block is installed, the inclined-plane of slanted kicking block contacts with push rod.
Mold cavity rotary plastic injection mould of the present invention is applicable in various arc products (the UT product in the water-drainage tube part for example, this product mainly play in the pipeline foul smell problem that stops the refluence of ducted foul smell at UT pipe bottom ponding and the cause) processing; Be characterized in being installed in lower impressions on the rotating mechanism, after injecting products is accomplished, take down upper impression and the core mould of pulling out the product straight-tube portion; Arc core mould is connected straight-bar, open rotating mechanism and make the lower impressions rotation and drive product simultaneously, about about Rotate 180 °; The arc core breaks away from product, and this moment, the push rod of cast gate below began to collide with the inclined-plane of slanted kicking block, continued in lower impressions under the situation of rotation; Push rod drives product gate part jack-up entire product and breaks away from lower impressions, and the one, the die cavity rotation does not have fork, and injection machine is big or small corresponding with converted products; Equipment utilization is reasonable, drives entire product by push rod jack-up product cast gate and from lower impressions, deviates from, and the demoulding is smooth; Realize automation; Do not need to adorn in addition manipulator or manual operations, labor strength is low, and production efficiency is high.
Mold cavity rotary plastic injection mould of the present invention; Its described rotating mechanism comprises the rotating disk that lower impressions is installed, and connects the rotating shaft of rotating disk, drives gear, the bearing of rotating shaft; Promote the tooth bar and the power that is connected tooth bar of gear; In actual product, the technical scheme of rotating mechanism is a lot, can adopt rotating disk, rotating shaft, gear, tooth bar and power to form.Its described power is motor or oil motor or hydraulic jack, and its power is available internal combustion engine etc. also.

The specific embodiment
The invention discloses a kind of mold cavity rotary plastic injection mould; Comprise the mould that upper and lower die cavity and core are formed; The bottom that it is characterized in that lower impressions 8 is installed on the rotating mechanism; Push rod 6 is installed in cast gate 7 belows of lower impressions 8, and slanted kicking block 9 is installed on the lower impressions support plate, and the inclined-plane of slanted kicking block 9 contacts with push rod 6.After injecting products is accomplished, take down upper impression, and pull out the core mould of product straight-tube portion, arc core mould is connected straight-bar; Like Fig. 1-shown in Figure 3, open rotating mechanism and make lower impressions 8 rotations and drive product simultaneously, about about Rotate 180 °, arc core 11 disengaging products 10; This moment, push rod 6 beginnings of cast gate 7 belows were collided with the inclined-plane of slanted kicking block 9, like Fig. 4, shown in Figure 5, continued under the situation of rotation in lower impressions 8, and push rod 6 drives 7 jack-up of product cast gate entire product and breaks away from lower impressions 8; The advantage of this structure is that the die cavity rotation does not have fork, and injection machine is big or small corresponding with converted products, and equipment utilization is reasonable; Drive entire product by push rod 6 jack-up product cast gates 7 and from lower impressions 8, deviate from, the demoulding is smooth, realizes automation; Do not need to adorn in addition manipulator or manual operations, labor strength is low, and production efficiency is high.Its rotating mechanism comprises the rotating disk 5 that lower impressions 8 is installed; Connect the rotating shaft 4 of rotating disk 5; Drive gear 2, the bearing 3 of rotating shaft 4, promote the tooth bar 1 and the power that is connected tooth bar 1 of gear, in actual product; The technical scheme of rotating mechanism is a lot, can adopt rotating disk, rotating shaft, gear, tooth bar and power to form.Its described power is motor or oil motor or hydraulic jack, also available internal combustion engine etc.
