Description

Technical field

The utility model refers to a product that is a tool for making a plastic bucket with a handle.

BACKGROUND OF THE INVENTION

A syringe disclosed in WO 1998/022273 is known for the manufacture of a bucket with a handle centrally attached to the bucket by the projections of the handle that enter diametrically opposed openings into the bucket. The shape consists of a movable and stationary half, which form a bucket for forming a bucket corresponding to the bucket shape and a handle for forming a handle corresponding to the shape of the handle. It is completely radially distant from the bucket socket. The handle of the handle is externally limited by a movable portion of the shape corresponding to each projection. This movable part is mounted on a "hand" attachment connected to a pull-out plate and associated pull-out pins to dispose of the handle. An actuator is connected to the arm, which is configured to move the movable portion of the form with the handle to contact with the openings of the bucket when the tilting movement of the tilting plate is complete.

The technical nature of the utility model

The product constituting a tool for the production of a plastic bucket with a handle consists of two blocks - right (stationary) and left (movable), on the dividing line between which are the outer and inner shaping surfaces of the product "plastic bucket with handle"; hot-channel injection molding system; mechanical device; plate end; ejection system; pusher and pull-out flange. The mechanical device is made up of two pins, mounted on two rolls, through which they move at a certain angle to the axis of opening and closing of the syringe and two pieces of plate moving at the same angle via T-channels in the movable block. The mechanical device ensures the shaping of the ends of the handle and the openings of the bucket, which enables the mobility of the two elements in the assembled state.

On one cycle with this product, a set of plastic bucket with handle is manufactured, while maintaining the mobility of its elements to each other in the assembled state, which leads to optimization of the production process and increase labor productivity.

Description of the attached figure

The figure is a schematic diagram of a tool for making a plastic bucket with a handle.

Examples of implementation

The syringe consists of two blocks: a right block (1) which is stationary and a left block (3) which is movable. On the dividing line between the fixed block (1) and the movable block (3), the outer and inner shaping surfaces of the plastic bucket with handle are made. A hot duct casting system (2) is located in block (1). In block (3) there is a mechanical device for shaping the edges of the handles and openings of the buckets, which is made up of two pins (4) and (5) mounted on rollers (12) and (13), through which they move under a defined angle with respect to the axis of opening and closing of the syringe and two plates (6) and (7) that move at the same angle via the T-grooves made in the same block (3). An ejection system (9) is actuated in the end plate (8), which is actuated by a pusher (10) and connected to a flange (11).

Application (use) of utility model

The left block (3) moves to the right (forward) to the right block (1), adheres tightly to it and the syringe closes. The outer and inner shaping surfaces create a blank space shaped by the elements of the article - a bucket and a handle. The hot duct casting system (2) injects preheated and metered quantities of material into the enclosure. After a certain time of cooling, the pins (4) and (5), through the rollers (12) and (13), and the plates (6) and (7), through the T-grooves, are mechanically removed from the molding zone. The left (3) unit moves to the left (back), whereby the ejection system (9) embedded in the plate is actuated by a pusher (10) and the associated flange (11) displaces the article.

Claims (1)

Claims Plastic bucket injection mold consisting of a fixed block (1) right and a movable block (3) left, hot duct casting system (2), end plate (8) with an ejector system (9), actuated by a pusher ( 10) and connected to a pull-out flange (11), characterized in that a mechanical device for forming the ends of the handle and the openings of the bucket, consisting of two pins (4) and (5) is arranged in the movable block (3). ) mounted on rollers (12) and (13) through which they move at a certain angle to the opening and closing axis Arjan of the mold, and two plates (6) and (7) traveling at the same angle by means of T-shaped slots made in the same block (3).
