Abstract
An integrated cylinder runner plate of an injection die comprises a die solid plate and a runner plate. A runner is arranged in the runner plate, the runner plate is connected with a cavity plate via a transitional plate, a cavity is mounted in the cavity plate, a spray nozzle is mounted in the transitional plate, and two ends of the spray nozzle are respectively communicated with the runner and the cavity. The integrated cylinder runner plate is characterized in that a cylinder is mounted on the runner plate and connected with a valve needle, and the valve needle extends into the runner and the spray nozzle. The cylinder is mounted on the runner plate, so that the cylinder and the runner plate are assembled integrally, the valve needle connected into the cylinder does not penetrate through the runner plate but directly extends into the runner of the runner plate, the problem of bending and deformation of the valve needle due to heat expansion and cold contraction of the runner plate is avoided, the service life of the valve needle is prolonged, repair and replacement costs are reduced, and expense is saved.
Description
Technical field
The utility model relates to annotates the embryo mould, particularly relates to a kind of integral type cylinder runner plate of annotating the embryo mould, belongs to the plastics machinery field.
Background technology
Adopt needle valve runner mould to produce plastic bottle preform, its advantage is: after plastic raw materials injected mould cavity, cylinder drove needle work, the clout of staying in runner and the nozzle (cast gate material) is clamp-oned in the die cavity, making on the plastic bottle preform after the moulding does not have the cast gate material, need not prune, and saves man-hour.The needle valve runner mould primary structure of prior art comprises solid plate and runner plate, be shaped on runner in the runner plate, runner plate is through rebound connecting-type chamber plate, die cavity is installed in the cavity plate, nozzle is installed in the rebound, two of nozzle is communicated with runner and die cavity respectively, cylinder is installed in solid plate, cylinder connects needle, and needle passes runner plate and stretches in runner and the nozzle, and the shortcoming of its existence is: runner plate need be heated when producing, be in the heat expansion state, needle passes runner plate and is in normal operating conditions, but when not producing, the runner plate cooling is dwindled, needle is pushed by the runner plate of shrinkage, be in case of bending, easy deformation, needle is short service life.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, and the assembling of a kind of cylinder and runner plate one is provided, and the influence that makes the cylinder needle not expanded with heat and contract with cold by runner plate is not crooked, indeformable, the notes embryo mould integral type cylinder runner plate of long service life.
The technical scheme that the utility model is annotated embryo mould integral type cylinder runner plate is: comprise mould solid plate and runner plate, be shaped on runner in the runner plate, runner plate is through rebound connecting-type chamber plate, die cavity is installed in the cavity plate, nozzle is installed in the rebound, and two of nozzle is communicated with runner and die cavity respectively, it is characterized in that on the described runner plate cylinder being installed, cylinder connects needle, and needle stretches in runner and the nozzle.
Notes embryo mould integral type cylinder runner plate of the present utility model, cylinder is installed on the runner plate, make the assembling of cylinder and runner plate one, the needle that is connected in the cylinder need not pass runner plate again, but directly stretch in the runner of runner plate, avoided needle to cause the phenomenon of needle bending, distortion to take place because of runner plate expands with heat and contract with cold, make needle service life, reduce maintenance, replacement cost, cost saving.
Notes embryo mould integral type cylinder runner plate of the present utility model is shaped on the cylinder intake hole in the described solid plate, air admission hole is communicated with cylinder, and the cylinder intake hole is opened in solid plate, and cylinder intake is convenient.
Description of drawings
Fig. 1 is that the utility model is annotated embryo mould integral type cylinder runner plate structural representation.
The specific embodiment
The utility model relates to a kind of notes embryo mould integral type cylinder runner plate, as shown in Figure 1, comprise mould solid plate 1 and runner plate 2, be shaped on runner 21 in the runner plate 2, runner plate 2 connects cavity plate 4 through rebound 3, die cavity 5 is installed in the cavity plate 4, nozzle 6 is installed in the rebound 3, and two of nozzle 6 is communicated with runner 21 and die cavity 5 respectively, it is characterized in that installing on the described runner plate 2 cylinder 7, cylinder 7 connects needle 8, and needle 8 stretches in runner 21 and the nozzle 6.This programme is installed in cylinder 7 on the runner plate 2, make cylinder 7 and the assembling of runner plate 2 one, the needle 8 that is connected in the cylinder 7 need not pass runner plate 2 again, but directly stretch in the runner 21 of runner plate 2, the phenomenon of having avoided needle 8 to cause needle bending, distortion because of runner plate 2 expands with heat and contract with cold takes place, make needle service life, reduce maintenance, replacement cost, cost saving.Be shaped on cylinder intake hole 9 in the described solid plate 1, air admission hole is communicated with cylinder 7, and the cylinder intake hole is opened in solid plate, and cylinder intake is convenient.
Claims (2)
