Description

Technical Field

[0001] The present invention relates to the technical field related to building construction, and specifically to a forming device for a lightweight and high-strength composite display cabinet. Background Art

[0002] A display cabinet is a display stand that provides protection for commodity display. The color can be selected according to the store decoration. The display cabinet has a firm structure, is easy to disassemble and assemble, and is convenient for transportation. It is widely used in company exhibition halls, exhibitions, department stores, advertisements, etc., and is widely used in industries such as handicrafts, gifts, jewelry, mobile phones, glasses, watches, tobacco and alcohol, cosmetics, etc.; and the display cabinet made of composite materials is widely used due to its relatively light quality and high strength, and its various components need to be injection molded by injection molding equipment during actual processing;

[0003] The Chinese patent document with the publication number CN100509361C discloses a method and device for manufacturing a structural component with a dense polyurethane (PUR) sealing layer. The solution includes placing the structural component into a mold, in which there is a cavity between the surface of the structural component to be coated and the inner wall of the mold facing this surface in the closed state, and the components of the dense polyurethane, optionally with additives, are injected into the mold containing the structural component through a mixing head and a pouring channel. The mixing head is connected to the mold to fill the cavity, and a pressure Pist related to the cavity pressure is measured in the input of the components to the mixing head, in the pouring channel of the mold, or in an overflow cavity, and when the measured pressure Pist reaches a predetermined pressure Pab, the input of the components is ended and the mixing head is switched to a recirculation state;

[0004] However, the structure of the forming mold in the above solution is relatively simple, and there is no special structure provided after injection molding to promote better uniform distribution of the molten injection liquid in the mold, resulting in pores in some positions of the formed component, thus affecting the overall strength of the component. Therefore, the present invention proposes a forming device for a lightweight and high-strength composite display cabinet to solve the above problems. Summary of the Invention

The setting of the wind-receiving annular plates 37 can improve the wind-receiving effect of the impact heads 35, so as to achieve the purpose of increasing the movement amplitude of the impact heads 35.

[0049] Embodiment 4: On the basis of Embodiment 3, a secondary support structure and a tertiary support structure are fixedly installed on the base 1.

When the return spring 49 is in the reset state, the secondary piston 47 moves to the bottom position of the inner cavity of the secondary piston cylinder 41. When the hydraulic mechanism 4 is in the forward movement, the air pressure values in the primary piston cylinder 40 and the secondary piston cylinder 41 are in a gradually increasing trend. The force generated by the clamping of the second mold 5 and the first mold 2 drives the connecting rod 44, thereby driving the piston rod 43 and the primary piston 42, so that the air pressure in the secondary piston cylinder 41 increases, and part of the gas is stored in the secondary piston cylinder 41. In the subsequent process of the injection molding machine 6 injecting the injection liquid into the injection cavity 13, the gas stored in the secondary piston cylinder 41 is gradually released, so that airflows are generated in the middle circulation groove 26 and the edge circulation groove 27, thereby achieving the purpose of auxiliary heat dissipation, and at the same time making the impact head 35 receive wind, so that the impact head 35 collides with the installation pipe 32, thus avoiding the problem that additional power sources are required for gas flow.

The impact head (35) is conical in shape, and when the impact head (35) is not stressed, the impact head (35), the tremor spring (34), and the air hole (36) are coaxially arranged. The end of the impact head (35) extends into the air hole (36). During the flow of the air flow in the installation pipe (32), the air flow forms an impact force on the impact head (35), and under the elastic force of the tremor spring (34), the impact head (35) continuously forms an impact force on the side wall of the installation pipe (32), so that the second mold (5) vibrates slightly, so that the injection liquid in the injection cavity (13) can be filled more fully.

8. The forming device of a lightweight and high-strength composite material display cabinet according to claim 7, characterized in that: The lower auxiliary uniform distribution structure (31) has the same structure as the upper auxiliary uniform distribution structure (30), and the setting directions of the impact heads (35) in the lower auxiliary uniform distribution structure (31) and the upper auxiliary uniform distribution structure (30) are opposite. Wind receiving annular plates (37) are integrally formed on the inclined surfaces of the impact heads (35).

9. The forming device of a lightweight and high-strength composite material display cabinet according to claim 8, characterized in that: A secondary support structure and a tertiary support structure are fixedly installed on the base (1). A primary piston cylinder (40) and a secondary piston cylinder (41) are respectively fixedly installed on the secondary support structure and the tertiary support structure. A primary piston (42) is movably installed in the inner cavity of the primary piston cylinder (40). A piston rod (43) is fixedly connected to the outer end of the primary piston (42). The end of the piston rod (43) is fixedly connected to a connecting rod (44). The other end of the connecting rod (44) is fixedly connected to the movable seat (3). A primary pipeline connector (45) and a secondary pipeline connector are arranged at the bottom of the primary piston cylinder (40). The primary pipeline connector (45) is connected to the intake pipeline connector (28) through an air supply hose.

10. The forming device of a lightweight and high-strength composite material display cabinet according to claim 9, characterized in that: A tertiary pipeline connector is arranged at the bottom of the secondary piston cylinder (41). The tertiary pipeline connector is connected to the secondary pipeline connector through a connecting pipe (46). A secondary piston (47) is movably installed in the inner cavity of the secondary piston cylinder (41). A limiting ring (48) is fixedly connected to the end opening of the secondary piston cylinder (41). A return spring (49) is movably installed in the inner cavity of the secondary piston cylinder (41). The two ends of the return spring (49) are respectively abutted against the secondary piston (47) and the limiting ring (48). An air inlet (52) is formed in the root side wall of the primary piston cylinder (40). A check valve is arranged in the air inlet (52) to enable gas to enter the primary piston cylinder (40) from the outside. When the return spring (49) is in a reset state, the secondary piston (47) moves to the bottom position of the inner cavity of the secondary piston cylinder (41). When the hydraulic mechanism (4) is in a forward movement, the air pressure values in the primary piston cylinder (40) and the secondary piston cylinder (41) are in a gradually increasing trend.
