Description
Technical field
The invention belongs to plastic-injection moulding machine tool design field, be specifically related to a kind of injection head of vertical plastic injection forming machine.
Background technology
Disk type plastic injection moulding machine is a kind of equipment of making plastic sole that is exclusively used in, often be provided with simultaneously on the used disk and overpay the die for shoe-sole of same style, different yardages, therefore mould need be arranged on the rotating disk, for mould gradation injection moulding that the plastics plastic-injection moulding machine is identical to style, yardage is different and the process operations such as sole of conveniently carrying out die sinking and taking out forming.
Disk type plastic injection moulding machine is owing to select the difference of preformed mechanism for use, generally be divided into two kinds of horizontal plastic injection mo(u)lding machine and vertical plastic injection forming machines, horizontal plastic injection mo(u)lding machine has the preformed mechanism that horizontal direction is provided with, and vertical plastic injection forming machine has the preformed mechanism that vertical direction is provided with.
The injection head that traditional vertical disc formula plastic-injection moulding machine is adopted is provided with the material feeding duct in its body, the charging aperture in described material feeding duct is arranged on the upper surface of injection head body, and the sprue in described material feeding duct is arranged on the lower surface of injection head body.
The shortcoming of traditional vertical plastic-injection moulding machine is in the process of operate as normal, and the fluid foods that has part to plastify easily spills from sprue, the material situation also promptly occurs leaking.Leak material and can bring unnecessary economic loss to the owner.
Summary of the invention
The object of the present invention is to provide a kind of injection head of preventing the vertical plastic injection forming machine of leak-stopping material.
The technical scheme that realizes the injection head of the object of the invention is: a kind of injection head of vertical plastic injection forming machine is provided with the material feeding duct, the charging aperture and the sprue in described material feeding duct in its body; Be inserted with in the described sprue and get final product the injection mouth that material feeding can be prevented the leak-stopping material again; The basic configuration of described injection mouth is up big and down small T shape, and its top is sealing, and its underpart is a discharging portion; Described sealing can hide and seal up sprue, and described discharging portion is provided with tapping channel, and to stretch out sprue also be the lower surface that the injection head body is hanged down in the bottom of discharging portion in the bottom of discharging portion.
Tapping channel in the described injection mouth is the duct of Y shape for the basic configuration that vertically is arranged in the discharging portion, perhaps for vertically being arranged on the groove on the discharging portion outer surface.
The charging aperture of described injection head body is positioned at the top of injection head body, and sprue is positioned at the bottom of injection head body.
The screwed pipe that the bottom centre place of described injection head body is provided with screw and matches with described screw, the centre bore of described screwed pipe is connected with the material feeding duct, thereby makes the centre bore of described screwed pipe become the sprue in material feeding duct; The diameter of the sealing of described injection mouth is greater than the aperture of screwed pipe centre bore.
Described injection head also is provided with and stops the material feeding controlling organization.
The described material feeding controlling organization that stops to comprise the substrate of fixedlying connected with the injection head body and inspection flitch, sliding pin, contact and the travel switch with locating hole that are arranged on the substrate; Described sliding pin passes the locating hole on the described substrate, fixedly connected with described inspection flitch in the lower end of described sliding pin, fixedly connected with described contact in the upper end of described sliding pin, the maximum gauge of described contact is greater than the aperture of locating hole on the described substrate, and described contact can trigger the described travel switch that is fixedly installed on the described substrate in the process that moves upward.
Described injection head body interior or its outer surface are provided with heater.
The present invention has beneficial effect:
(1) injection head among the present invention has plugged custom-designed injection mouth owing to having adopted in sprue, when injection head is not pressed on the mould, this kind injection mouth is under the pressure of material, described sealing can hide and seal up sprue, and make the bottom of its discharging portion hang down the lower surface of injection head body, can prevent that material from spilling from sprue; When injection head is pressed on the mould, owing to hang down the mould that the injection mouth discharging portion of injection head body lower surface at first contacts, so injection mouth is by the mould jack-up that makes progress, thereby make fluid foods from the tapping channel of injection mouth discharging portion, to flow out sprue and enter into mold cavity, get final product the technique effect that material feeding can be prevented the leak-stopping material again so the injection head among the present invention has.
(2) also be provided with when stopping the material feeding controlling organization when injection head of the present invention, can control the injection volume of material easily, because after material is filled with mold cavity, will from the steam vent of mould, overflow, thereby with the jack-up that makes progress of the inspection flitch in the controlling organization, the inspection flitch promotes contact by sliding pin and triggers travel switch, the trip switch is used to control injection cylinder, after the trip switch is triggered, injection cylinder stops injection, and the material that just can guarantee to be injected in the mould just in time is a suitable amount.
(3) when also being provided with heater in the injection head of the present invention, can better the material that is arranged in the material feeding duct of injection head be kept fluid state, effectively avoid taking place material stops up sprue because of cooling phenomenon.
(4) be provided with screw and during with screwed pipe that described screw matches, its advantage is when installing and need repairing the cleaning injection mouth when the bottom centre of described injection head body place, screwed pipe need be pulled down and to get final product, have advantage easily and efficiently.
