Injection molding is a method for producing and molding industrial products, and is to make thermoplastic plastics or thermosetting plastics into plastic products with various shapes by using a plastic molding die.
At present, plastic products obtained by injection molding processing need to be processed by cutting off surface nozzle materials, and the nozzle materials are formed by injecting liquid plastic into a seal in the injection molding process and cooling after the injection molding processing. In the commonly seen plastic products, the water outlet cutting is usually completed manually, the manual operation not only consumes time, but also is easy to fatigue, and the cost of manpower is increased; especially for large-batch production and processing, the efficiency of manual production is too low, and the whole production progress is influenced finally, so that pressure is caused to the production of enterprises.
SUMMERY OF THE UTILITY MODEL
Based on this, it is necessary to provide an injection molding machine that can amputate mouth of a river automatically, including movable mould and cover half that set up from top to bottom, be formed with the die cavity between movable mould and the cover half, its characterized in that, the upper surface of cover half is provided with the recess, the recess with the lower surface of movable mould forms the runner, the runner with the die cavity intercommunication, injection channel has been seted up to the movable mould, injection channel with the runner intercommunication, the lower surface of movable mould corresponds the end of runner is provided with the cutting ring, the cutting ring orientation the one end parallel and level of die cavity the tip of runner sets up just the lateral wall of cutting ring with the recess is sealed cooperation setting each other.
The utility model discloses during the use, pour into melting plastic into the die cavity through injection channel and runner, wherein, melting plastic in the runner can enter into the die cavity through the cutting ring, melting plastic cooling shaping in the die cavity obtains behind the plastic product, when the movable mould left the cover half, the cutting ring on the movable mould can remove along with the movable mould, consequently the crisscross removal between one end that the cutting ring is close to the die cavity and the die cavity can be with the mouth of a river of shaping in the runner follow plastic product excision, thereby can reach the mesh of the mouth of a river on the automatic excision plastic product, the production efficiency is greatly improved.
Further, the bottom of recess corresponds the cutting ring is provided with the mounting groove, the mounting groove orientation the one end parallel and level of die cavity the tip setting of runner, the cutting ring inlays to be located in the mounting groove just the inside wall parallel and level of cutting ring the inside wall of recess and the lower surface setting of movable mould.
Wherein, the inlaying of cutting ring is established in the mounting groove, and the inside wall setting of the inside wall parallel and level recess of cutting ring, therefore the melting plastic in the runner can not receive blockking of cutting ring when flowing through the runner, and then can guarantee going on smoothly of melting plastic process of moulding plastics.
Further, the bottom of one end of the groove close to the cavity gradually rises along the direction towards the cavity to form a flowing groove.
The bottom of influx groove is lifted along the direction towards the die cavity gradually, therefore the bottom of the cutting ring that the lateral wall of inside wall parallel and level influx groove set up is the cutting edge form to can increase the pressure of cutting ring to the juncture of mouth of a river and plastic products, can make the cutting ring can cut down the mouth of a river from plastic products more easily, avoid the cutting process to cause destruction to plastic products.
Furthermore, the included angle between the bottom of one end of the groove close to the cavity and the horizontal plane is 30-60 degrees.
Further, the cross section of the inflow groove is rectangular.
The cross-section that flows into is the rectangle, then forms the cross-section at the mouth of a river in the flowing in groove and also is the rectangle, and consequently the side at the mouth of a river in the flowing in groove is vertical plane, and the cutting ring is when cutting the mouth of a river, and the removal at the both sides edge of cutting ring can not receive blockking of mouth of a river and only produces relative slip with the mouth of a river, consequently the utility model discloses can further make the bottom of cutting ring more easy to the cutting at the mouth of a river, can effectively prevent that the cutting process from damaging plastic goods.
Further, the height of the cross section of the inflow groove is larger than the width of the cross section of the inflow groove.
The height of the cross section of the inflow groove is larger than the width of the cross section of the inflow groove, so that the contact width between the bottom of the cutting ring and a water gap in the inflow groove is smaller under the condition that the sectional area of the inflow groove is kept unchanged, and the cutting of the cutting ring on the water gap is facilitated.
The principle and effect of the present invention will be further explained below with reference to the above technical solutions and the accompanying drawings:
the utility model discloses in, when the movable mould left the cover half, the cutting ring on the movable mould can remove along with the movable mould, consequently the crisscross removal between the one end that the cutting ring is close to the die cavity and the die cavity can be with the mouth of a river of shaping in the runner from the plastic product excision to can reach the purpose of the mouth of a river on the automatic excision plastic product, greatly improve production efficiency.

Detailed Description
To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples:
as shown in fig. 1-2, an injection molding machine capable of automatically cutting off a water gap comprises a movable mold 1 and a fixed mold 2 which are arranged up and down, wherein a cavity 3 is formed between the movable mold 1 and the fixed mold 2, and is characterized in that a groove is formed in the upper surface of the fixed mold 2, the groove and the lower surface of the movable mold 1 form a runner 21, the runner 21 is communicated with the cavity 3, an injection passage 11 is formed in the movable mold 1, the injection passage 11 is communicated with the runner 21, a cutting ring 12 is arranged at the end, corresponding to the runner 21, of the lower surface of the movable mold 1, the cutting ring 12 faces towards one end flush with the cavity 3, the end part of the runner 21 is arranged, and the outer side wall of the cutting ring 12 and the groove are arranged in a sealing and matching manner.
The utility model discloses during the use, pour into the melting plastic into die cavity 3 through injection channel 11 and runner 21, wherein, the melting plastic in the runner 21 can enter into die cavity 3 through cutting ring 12, after the melting plastic cooling shaping in the die cavity 3 obtained the plastic product, when movable mould 1 left cover half 2, cutting ring 12 on the movable mould 1 can remove along with movable mould 1, consequently, the crisscross removal between one end that cutting ring 12 is close to die cavity 3 and the die cavity 3 can be with the mouth of a river of shaping in runner 21 from the plastic product excision, thereby can reach the purpose of the mouth of a river on the automatic excision plastic product, and the production efficiency is greatly improved.
