Abstract
The utility model discloses a cold material-dropping machine, which is arranged at a material-dropping board of a three-board injection mold. The utility model comprises an outer cylinder, a plunger, and a spring, wherein the plunger is actively provided at a plunger cavity of the outer cylinder and compresses the spring in the plunger cavity, the opening of the outer cylinder is provided with a retainer element to prevent the plunger from disengaging from the plunger cavity of the outer cylinder. The said retainer element is composed of a resilient positioning pin which is radially provided at the wall of the outer cylinder and a locating hole which is provided at the external ring wall of the plunger. When the plunger rises to a limiting position, the resilient positioning pin is against into the locating hole. When demoulding, the utility model of cold material-dropping machine can use the elastic deformation of the spring to drive the plunger to cause nozzle materials to rebound off a nozzle pushing paddle at the moment that the nozzle materials drop off from the nozzle barbed needle, without picking off by hand or mechanical arm, which ensures the safety in production, reduces the molding time and enhances the production efficiency.
Description
Technical field
The utility model relates to plastics and rubber injection mold field shaping technique, particularly a kind of cold burden device that comes off.This cold burden comes off device applicable to three plate injection molds.
Background technology
After mouth of a river material breaks away from crochet hook in the plastic cement mould cold runner of the at present thin mouth of a river, often be bonded on the stripper plate.Therefore must win with artificial or manipulator, increase operator's potential safety hazard, prolong molding time, reduce production efficiency.
The utility model content
The purpose of this utility model is to provide a kind of cold burden that is installed in three plate injection moulds device that comes off, and breaks away from the many weak points that exist to solve the existing plastic cement mould mouth of a river, thin mouth of a river material.
The purpose of this utility model can be achieved through the following technical solutions:
The cold burden device that comes off, it is characterized in that: this cold burden device that comes off is installed in the stripper plate of three plate injection membrane tools, it comprises outer shell, piston, spring, the piston motion stops is compressed in this plunger shaft in the plunger shaft of outer shell and with spring, is provided with one at the cylinder mouth of outer shell and prevents that piston breaks away from the locking component of outer shell plunger shaft fully.
Described thrust member is made of with the locating hole that is opened on the piston external annulus an elastic positioning pin that radially is installed on the outer shell casing wall, and when piston rose to extreme position, elastic positioning pin headed in the described locating hole.
Described elastic positioning pin comprises that an end is alignment pin, locating pin spring and the plug of cup head, and plug is installed in alignment pin and retainer spring in one installing hole that radially is opened on the outer shell casing wall.
Described piston is the hollow cylinder structure, at the bottom of it outwardly.
The cylinder mouth of described outer shell is reducing, and described reducing cooperates with the piston clearance.
For device that cold burden is come off is installed on the stripper plate of three plate injection molds, have a screwed hole at the cylinder bottom center of outer shell.
When the installation cold burden comes off device, an installing blind that matches with the outer shell external diameter and a bolt hole offered in appropriate location on the stripper plate of three plate injection molds, the cold burden device that comes off is pressed in the installing blind, with a bolt passing through bolt hole and screw in the screwed hole on the outer shell cylinder bottom and tighten this cold burden device that comes off is installed on the stripper plate.
During the demoulding, cold burden of the present utility model comes off device can be at the material disengaging mouth of a river, mouth of a river crochet hook in a flash, utilize the elastic deformation of spring to promote piston with dried up mouthful of push pedal of mouth of a river material bullet, allow mouth of a river material come off automatically, and needn't win with artificial or manipulator, guarantee safety in production, shortened molding time, improved production efficiency.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the come off structural representation of device of the utility model cold burden.
Fig. 2 is the utility model cold burden device working state schematic representation that comes off.
The specific embodiment
Referring to Fig. 1, this cold burden device that comes off comprises outer shell 1, piston 2, spring 3, and piston 2 is the hollow cylinder structure, has a locating hole 21 on the external annulus of piston 2.The cylinder mouth of outer shell 1 is reducing 11, has a screwed hole 12 at the cylinder bottom center.
Piston 2 motion stops outwardly, are compressed in spring 3 in this plunger shaft 11 at the bottom of it outwardly at the bottom of it in the plunger shaft 11 of outer shell 1.Reducing 11 and piston 2 matched in clearance.
On the casing wall 12 of outer shell 1, have radially a locating hole 121, by an end is that the elastic positioning pin 4 that alignment pin 41, locating pin spring 42 and the plug 43 of cup head constitutes is installed in the locating hole 121, wherein alignment pin 41 is positioned at the inboard of casing wall 12, plug 43 is positioned at the outside of casing wall 12, and spring 3 is between alignment pin 41 and plug 43.
Locating hole 21 on the external annulus of elastic positioning pin 4 and piston 2 constitutes together and prevents that piston 2 breaks away from the locking component of outer shell 1 plunger shaft 11 fully.
When piston 2 rose to extreme position, the cup head of alignment pin 41 1 ends in the elastic positioning pin 4 pushed on the external annulus of piston 2 and has in the locating hole 21, with the axially-movable of limited piston 2.
When the installation cold burden comes off device, an installing blind 51 that matches with outer shell 1 external diameter and a bolt hole 52 offered in appropriate location on the stripper plate 5 of three plate injection molds, the cold burden device that comes off is pressed in the installing blind 51, passes bolt hole 52 and screw in the screwed hole 12 on outer shell 1 cylinder bottom and tighten with a bolt 53 this cold burden device that comes off is installed on the stripper plate 5.
During the demoulding, the cold burden device that comes off can expect that 6 break away from mouth of a river crochet hooks 7 in a flash at the mouth of a river, utilize the elastic deformation of spring 3 to promote piston 2 with dried up mouthful of push pedal of mouth of a river material 6 bullets, allow mouth of a river material 6 come off automatically, and needn't win with artificial or manipulator, guarantee safety in production, shortened molding time, improved production efficiency.
When answering mould, die cavity A plate 8 promotes down, and piston 2 is pushed back in the outer shell 1 again, waits for action next time.
