Description

Cut off mouth of a river in injection mold mould and push up mouth of a river mechanism with higher speed

Technical Field

The utility model relates to a cut off mouth of a river ejecting mouth of a river mechanism with higher speed in injection mold mould.

Background

After the plastic product is subjected to injection molding, the water gap of the product and the separation of the product and the water gap generally need to be manually trimmed for the second time, and the appearance quality and the stability of the product are difficult to guarantee while the working procedures and the labor cost are increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides a cut off mouth of a river ejecting mouth of a river mechanism with higher speed in injection mold mould to above-mentioned technical difficult problem. The device comprises a product, a front template, a rear template, an ejector pin base plate, a rear template base plate, a first cutter, a second cutter, a cutter base plate, a cutter fixing plate, an oil cylinder, a rear mold core, a water gap ejector pin, a product ejector pin, an accelerating block, a pin and a stop block. The method is characterized in that: the lower ends of the first cutter and the second cutter are fixed on the cutter fixing plate, and the upper ends of the first cutter and the second cutter are positioned right below the water gap; the lower end of the cutter bottom plate is fixedly connected with the oil cylinder, and the upper end of the cutter bottom plate is fixedly connected with the cutter fixing plate; the upper end of the water gap thimble is positioned right below the water gap, and the lower end of the water gap thimble is fixed at the left end of the accelerating block; the upper end of the product thimble is positioned under the product, and the lower end of the product thimble is fixed on the thimble bottom plate; the pin is fixed in a hole formed in the accelerating block; the accelerating block can rotate by taking a pin as a shaft; the upper end of the stop block is fixedly connected with the rear template.

The utility model has the advantages that after the injection mold is closed and injected with mold, when the water gap is not cooled, the first cutter and the second cutter move upwards under the pushing action of the oil cylinder to cut off the water gap, so that the separation of the product from the water gap is realized, and the attractiveness of the water gap of the product is ensured; the mould is opened in die joint department behind injection moulding, top plate upward movement under the promotion of injection molding machine, make top plate promote product thimble and mouth of a river thimble upward movement together, accelerating block right-hand member is touching behind the dog lower surface, accelerating block left end uses the pin to be the rotary motion as the axle, mouth of a river thimble is for the accelerated upward movement of product thimble in order to push out the mouth of a river, realize breaking away from of mouth of a river and product, when saving the cost of labor and shortening the shaping cycle, the product automated production level has been promoted, and the mould is simple in structure, and injection moulding's product stability is strong.

Detailed Description

As shown in fig. 1-6, an accelerated water ejection mechanism for cutting off a water gap in an injection mold comprises a product 1, a front mold plate 2, a rear mold plate 3, an ejector pin bottom plate 4, a rear mold bottom plate 5, a first cutter 6, a second cutter 7, a cutter bottom plate 8, a cutter fixing plate 9, an oil cylinder 10, a rear mold core 11, a water gap ejector pin 12, a product ejector pin 13, an accelerating block 14, a pin 15 and a stop block 16.

As shown in fig. 4, after the injection molding of the mold is completed, when the nozzle is not yet cooled, the oil cylinder 10 pushes the cutter base plate 8 upwards, the cutter base plate 8 moves upwards to drive the cutter fixing plate 9 to move upwards, the first cutter 6 and the second cutter 7 move upwards under the drive of the cutter fixing plate 9 to cut off the nozzle, so that the separation of the nozzle and the product 1 is realized, and the appearance quality of the separation part of the nozzle of the product 1 is ensured.

As shown in fig. 1-6, after injection molding, the ejector base plate 4 moves upward under the pushing of the injection molding machine, the ejector base plate 4 drives the product ejector pin 13 and the acceleration block 14 to move upward, when the upper surface of the right end of the acceleration block 14 contacts the lower surface of the stopper 16, the right end of the acceleration block 14 stops moving upward, the left end of the acceleration block 14 rotates upward with the pin 15 as the axis, the nozzle ejector pin 12 moves upward with acceleration relative to the product ejector pin 13, so as to drive the nozzle ejector pin 12 to move upward with acceleration, so that the nozzle is ejected by the nozzle ejector pin 12 moving upward with acceleration, and automatic separation of the product 1 and the nozzle is realized.

The accelerated water outlet ejection mechanism for the water outlet cut in the injection mold is used for mold opening and closing of the accelerated water outlet ejection mechanism for the water outlet cut in the injection mold, the problem that the water outlet is manually removed to affect the attractiveness of a product can be solved, the automatic separation of the product and the water outlet is realized, the production and manufacturing period of the product is shortened, and the injection molding product is high in yield.

The above description is of the preferred embodiment of the present invention, and is intended to illustrate the content and the idea of the present invention, and the content of the present invention should not be construed as limiting the present invention.
