Technical Field

[0001] The utility model relates to the technical field of injection molding product production equipment, in particular to an automatic water inlet cutting device after the injection molding of a template is completed. Background Art

[0002] Injection molding is a common molding method for plastic products. Most plastic products are molded by injection molding, and injection molding products are widely used because of their high production efficiency and low production cost. After the injection molding of injection molding products is completed, there is a sprue left, which needs to be removed to form the required product.

[0003] The patent application CN214419470U discloses an automatic water outlet cutting device for injection molded products, including a frame, a mounting seat, a fixed seat and a plurality of cutting tools. The mounting seat is movably arranged on the frame, the fixed seat is fixedly arranged on the frame, and the mounting seat and the fixed seat are arranged in parallel; each of the cutting tools is arranged on the mounting seat, and each of the cutting tools faces one side of the fixed seat, and the fixed seat is provided with an avoidance position for avoiding the cutting tools. The utility model is used to cut off the water outlet of the injection molded product after the injection molding is completed to obtain the final injection molded product. The automatic water outlet cutting device for injection molded products can realize the mechanical and automated cutting of the water outlet of the injection molded product, improve the efficiency of water outlet cutting, reduce the production cost of cutting the water outlet of the injection molded product, and also reduce the direct contact between the operator and the cutting tool, thereby eliminating safety hazards.

[0004] Although the above scheme can realize mechanical and automated cutting of the sprue of injection molded products and improve the efficiency of sprue cutting, during the cutting process, due to the fixed position of the blade, it is not possible to quickly cut the sprue of injection molded products of different sizes, and its applicability is low. For this reason, we propose an automatic sprue cutting device after the template injection molding is completed. Utility Model Content

[0005] The main purpose of the utility model is to provide an automatic water outlet cutting device after the template injection molding is completed. By setting a moving unit and a cutting unit, the utility model solves the problem that the water outlets of injection molding products of different sizes cannot be quickly cut off due to the fixed position of the blade and the low applicability.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An automatic water inlet cutting device after the injection molding of a template is completed, comprising a main unit, a moving unit and a cutting unit arranged in the main unit, a material withdrawing unit arranged on the side of the main unit, and a clamping unit arranged above the main unit;

[0008] The moving unit comprises a U-shaped seat mounted on the inner bottom wall of the main unit, a screw rod movably arranged in the U-shaped seat, a moving part mounted on the side surface of the screw rod, a moving seat mounted on the top of the moving part, and a driving motor mounted on the input end of the screw rod;

[0009] The cutting unit comprises a fixed column installed in a moving seat, a moving block sleeved on the peripheral side of the fixed column, a cutting knife installed on the top of the moving block, and a positioning piece arranged on the side of the moving block.

[0010] Preferably, the main unit includes an L-shaped fixing seat and a placement plate installed on the inner side wall of the L-shaped fixing seat.

[0011] Preferably, the moving unit comprises a limiting washer installed on the inner side wall of the U-shaped seat, and the limiting washer is sleeved on the peripheral side surface of the screw rod.

[0012] Preferably, the positioning member includes a fixed plate installed on the side wall of the moving block, a moving through hole opened on the top of the fixed plate, a moving rod movably passing through and arranged in the moving through hole, a T-shaped slot opened on the inner bottom wall of the moving seat, a T-shaped block installed at the bottom of the moving rod, a moving plate installed at the top of the moving rod, and a connecting spring arranged between the T-shaped block and the moving plate and sleeved on the peripheral side of the moving rod.

[0013] Preferably, the material withdrawal unit includes a side connecting seat installed on the side wall of the L-shaped fixing seat, an electric push cylinder installed on the inner wall of the side connecting seat, and a push plate installed on the telescopic end of the electric push cylinder.

[0014] Preferably, the clamping unit includes a positioning plate installed on the inner side wall of the L-shaped fixing seat, a fixing through hole opened at the top of the positioning plate, a movable column movably passing through and arranged in the fixing through hole, a holding plate installed at the bottom of the moving column, a stretching plate installed at the top of the moving column, and a return spring having one end fixedly connected to the holding plate and the other end fixedly connected to the positioning plate.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, by means of the provided moving unit and cutting unit, when it is necessary to fix the injection molded product before cutting the water outlet, first, the stretching plate is lifted upwards, so that the moving column drives the holding plate to move upwards, and the return spring is compressed. After the injection molded product is placed on the placement plate, the force applied to the stretching plate is removed. Under the elastic force of the return spring, the holding plate presses against the injection molded product, and the injection molded product is fixed before cutting the water outlet. When it is necessary to cut the water outlet of the injection molded product, after completing the fixing of the injection molded product, the moving column can be pulled upwards to move the holding plate upwards. The plate makes the T-block away from the T-slot and compresses the connecting spring. At this time, the slidable movable block moves on the fixed column, so that the cutting knife and the water cutting outlet are located in the same plane, and the force applied to the movable plate is removed. Under the elastic force of the connecting spring, the T-block re-engages with the T-slot; then, the driving motor drives the screw rod to rotate, and the movable part can drive the cutting unit in the movable seat to move along the screw rod to perform the water cutting process; thereby realizing the rapid cutting of water outlets of injection molding products of different sizes and improving applicability.
