Description

Technical Field

[0001] The invention relates to the field of acrylic production equipment, in particular to an acrylic mould injection machine. Background Art

[0002] The traditional production process of organic glass is: two templates are clamped relative to each other and polymethyl methacrylate is injected into the clamping cavity, the two clamped templates are sent into a water pool for thermal polymerization, and then demolded by high-temperature molding. The applicant mentioned a vertical casting device and a casting method for organic glass in the patent previously applied for. The mold is placed vertically and the bottom of the mold is at the same horizontal plane in the vertical height. When the liquid is injected, the liquid accumulates at the same height at the bottom of the mold because it is relatively viscous. The accumulation speed is slow and air is easily introduced, resulting in bubbles in the product, affecting the product quality. Summary of the invention

Articulated seats are arranged at the front and rear sides of the lifting hydraulic cylinder. The cylinder body of the lifting hydraulic cylinder is connected and supported on the articulated seat through the front and rear fixed hinge shafts. The rod body of the lifting hydraulic cylinder is lifted and connected to the working frame upward. The rear side of the working frame is rotated to the middle and rear part of the turning frame through the turning axis. Multiple rows of transverse conveying wheel groups in the left and right directions and multiple rows of longitudinal conveying wheel groups in the front and rear directions are arranged on the turning frame. Positioning baffles in the left and right directions are arranged at the rear of the turning frame. The sliding guides on both sides of the positioning baffle are supported on the baffle supporting rails on both sides of the turning frame. Two turning hydraulic cylinders are connected at both sides of the rear of the turning axis of the turning frame, and the bottom of the turning hydraulic cylinder is hinged on the base.

[0005] Furthermore, it also includes a lower suction cylinder and a vacuum suction head. A plurality of lower suction cylinders are staggered and evenly arranged on the turning frame with transverse conveying wheel groups. The top of the lower suction cylinder is connected to the vacuum suction head.

[0006] Furthermore, it also includes a suction bracket, an upper suction cylinder and a vacuum suction cup. The rear of the flip frame is vertically connected to the suction bracket, the suction bracket is connected to the upper suction cylinder downwardly and perpendicularly to the flip frame, and the bottom of the upper suction cylinder is connected to the vacuum suction cup.

[0007] Furthermore, the rear portion of the flip frame is vertically connected to the suction bracket via a suction bracket lifting cylinder.

[0008] Furthermore, the longitudinal conveying wheel group includes a roller lifting cylinder and rollers. The roller lifting cylinders are connected to multiple cross beams in the front and rear directions of the turning frame. The roller lifting cylinders lift downward and are connected to multiple longitudinal plates along the front and rear directions of the turning frame. Multiple roller pillars are evenly distributed on the longitudinal plates, and the roller pillars support and connect rollers in the front and rear directions.

[0009] Furthermore, the base is provided with an inductive position switch corresponding to the working frame and / or the lifting hydraulic cylinder.

[0010] Furthermore, an adjusting screw is connected to the bottom of the positioning baffle, and the adjusting screw is driven by an adjusting motor arranged on the turning frame.

[0011] When the present invention is in operation, the conveying platform conveys the glass mold whose left, rear and right sides are clamped and sealed by elastic clamps toward the injection machine, and the glass mold is translated on multiple groups of transverse conveying wheel groups in the front and rear directions, and is translated as a whole onto the turning frame, and the roller lifting cylinder is controlled to lift the longitudinal plate to make the longitudinal conveying wheel group in the front and rear directions rise to lift the glass mold on the transverse conveying wheel group; when the control adjustment motor drives the adjusting screw, the positioning baffle moves on the baffle support track to meet the support requirements of glass molds with different lengths in the front and rear directions on the turning frame; synchronously or subsequently controlling the turning hydraulic cylinder to pull the rear of the turning frame, the turning frame rotates around the turning axis rotated with the working frame, and the front of the turning frame rotates upward, and the glass mold can move backward on the longitudinal conveying wheel group in the front and rear directions and is limited by the positioning baffle; controlling the lower suction cylinder to lift the vacuum suction head to vacuum the lower surface of the glass mold supported by the longitudinal conveying wheel group placed on the turning frame; synchronously or subsequently controlling the lifting hydraulic cylinder to work to lift the working frame The work frame is hinged to the base at the left end, and the lifting hydraulic cylinder body rotates to the left on the hinge seat through the hinge shaft, and at the same time lifts up the right side of the work frame, and the work frame supports the flip frame to rise; at this time, the glass mold is at the lowest position at the left rear corner and the highest position at the right front corner in the horizontal direction; the upper suction cylinder is controlled to descend and the vacuum suction cup sucks the upper surface of the glass mold, and after suction, the material can be poured through the front side port of the unpackaged glass mold. When the plane area of ​​the glass mold is large, the glass mold has a concave situation, and the upper plane of the glass mold can be pulled through the vacuum suction cup by the upper suction cylinder or the suction bracket lifting cylinder, and the slow opening and closing control is used to overcome the leakage problem caused by the rapid release of the plate casting caused by the above-mentioned concave; because when the glass mold is poured on the injection machine, only the left rear corner is the lowest, and the poured material liquid is all accumulated in the left rear corner, the feeding accumulation speed is fast, and it is conducive to the discharge of air in the glass mold, avoiding the generation of bubbles, and improving the quality of the final product.
