Abstract
The invention relates to a runner plate of a plastic tray injection mold. The runner plate comprises a press board provided with a glue injection port, a runner plate is mounted on the press plate; a runner frame is installed in the runner plate, the runner frame is provided with glue injection holes, the glue injection port is communicated with the glue injection holes. The runner plate is characterized in that the runner frame is in a * shape; the * shaped runner frame comprises an upper runner, a lower runner, a left runner, a right runner, a left-upper runner, a right-upper runner, a left-lower runner and a right-lower runner, wherein the length of both the left runner and the right runner is determined by the left-upper runner, the right-upper runner, the left-lower runner and the right-lower runner, a vertical left end runner is arranged at one end of the left runner, and a vertical right end runner is arranged at one end of the right runner. All the runners are provided with glue output ports, and the glue output ports are communicated with a mold cavity of the injection mold.
Description
Technical field
The present invention relates to the plastic pallet injection mold, particularly relate to a kind of runner plate of plastic pallet injection mold.
Background technology
In the storage such as various medicine foods, plastics chemical industry, raw material and logistics progress, usually need to use plastic pallet.Runner frame in the flow channel of injection die plate of existing plastic pallet mostly is the runner frame of king's font, the plastics that heat is melted are transported to the middle part of king's font runner frame by hole for injecting glue, each gum outlet around being transported to by the runner in king's font runner frame again, the shortcoming of its existence is: the gum outlet at 4 angles of king's font runner frame with about the distance of two gum outlets differ far away, mould often about plastics in the mold cavity at two gum outlet places be filled with, and the mold cavity at gum outlet place, 4 angles is not also filled with, cause injection moulding inhomogeneous, cause product rejection.
Summary of the invention
The objective of the invention is provides a kind of plastics that heat is melted to flow to each gum outlet close proximity in order to overcome the shortcoming of prior art existence, and discharging is balanced, guarantees the runner plate of a kind of plastic pallet injection mold of product quality.
The technical scheme of the runner plate of a kind of plastic pallet injection mold of the present invention is: comprise press plates, have gum-injecting port in the press plates, at press plates runner plate is installed, the runner frame is installed in the runner plate, have hole for injecting glue in the runner frame, gum-injecting port communicates with hole for injecting glue, it is characterized in that: described runner frame is M shape runner frame, described M shape runner frame comprises upper runner, lower flow channel, left runner, right runner, upper left runner, upper right runner, lower-left runner and bottom right runner, described left runner and right runner be shorter in length than upper left runner, upper right runner, lower-left runner and bottom right runner, be shaped with perpendicular left end runner one of left runner, one of right runner is shaped with perpendicular right-hand member runner, all runners all are shaped with gum outlet, and gum outlet communicates with the die cavity of injection mold.
The invention discloses a kind of runner plate of plastic pallet injection mold, set up meter and become M shape runner frame by being arranged on runner on the runner plate, the left runner of M shape runner frame and right runner are short runner, be shaped with the left end runner one of left runner, one of right runner is shaped with the right-hand member runner, the close proximity of each gum outlet around thereby the hole for injecting glue that makes M shape runner frame middle part arrives, reach the discharging equilibrium, and the design of this runner frame makes each position of mould that a gum outlet be arranged, make each position of product can both obtain balanced injection heat and melt plastics, guarantee product quality.
Description of drawings
Fig. 1 is the schematic top plan view of the runner plate of a kind of plastic pallet injection mold of the present invention.
The specific embodiment
The present invention relates to a kind of runner plate of plastic pallet injection mold, as shown in Figure 1, comprise press plates 1, have gum-injecting port in the press plates, at press plates runner plate 3 is installed, runner frame 2 is installed in the runner plate, have hole for injecting glue 5 in the runner frame, gum-injecting port communicates with hole for injecting glue 5, it is characterized in that: described runner frame 2 is M shape runner frame, described M shape runner frame comprises upper runner 30, lower flow channel 31, left runner 32, right runner 33, upper left runner 34, upper right runner 35, lower-left runner 36 and bottom right runner 37, described left runner 32 and right runner 33 be shorter in length than upper left runner 34, upper right runner 35, lower-left runner 36 and bottom right runner 37, be shaped with perpendicular left end runner 38 one of left runner, 33 1 of right runners are shaped with perpendicular right-hand member runner 39, all runners all are shaped with gum outlet 4, and gum outlet communicates with the die cavity of injection mold.Be designed to M shape runner frame by the runner frame 2 that will be arranged on the runner plate 3, the left runner 32 of M shape runner frame and right runner 33 are short runner, be shaped with left end runner 38 32 1 of left runners, 33 1 of right runners are shaped with right-hand member runner 39, the close proximity of each gum outlet 4 around thereby the hole for injecting glue 5 that makes M shape runner frame middle part arrives, reach the discharging equilibrium, and the design of this runner frame 2 makes each position of mould that a gum outlet 4 be arranged, make each position of product can both obtain balanced injection heat and melt plastics, guarantee product quality.
