Description

Technical Field

[0001] This utility model relates to the field of rubber injection molding machines, and in particular to a double-exit automatic high-efficiency rubber injection molding machine. Background Technology

[0002] A rubber injection molding machine is a common piece of equipment used to manufacture rubber products. It compresses rubber raw materials and then injects them into a mold with significant injection force, where they are molded. A rubber injection molding machine is a type of equipment used in the production of molded rubber products. It is mainly used for the production of molded rubber products such as electrical insulation parts, shock-absorbing pads, seals, shoe soles, and industrial rain boots. A typical rubber injection molding machine includes an injection unit, a mold opening and closing unit, a heating and cooling unit, a hydraulic transmission system, and an electrical control system. There are many types of injection molding machines. Based on the method of rubber plasticization, they can be classified as plunger type and screw type; based on the machine transmission type, they can be classified as hydraulic type and mechanical type; and based on the type of mold closing device, they can be classified as direct pressure type, hydraulic-mechanical type, and two-action type.

[0003] The prior art, patent number CN112372939B, describes a fully automatic rubber molding machine. The machine includes an injection zone containing two sequentially independent first and second mold units. A first cleaning zone and a second cleaning zone are respectively located on opposite sides of the injection zone. The first cleaning zone is connected to a first material handling zone, and a first material handling mechanism is located above the first material handling zone. The second cleaning zone is connected to the second material handling zone, and a second material handling mechanism is located above the second material handling zone. Figure 3 , 4 The invention discloses that "both the first cleaning zone 5 and the second cleaning zone 6 are equipped with an upper mold cleaning mechanism. The upper mold cleaning mechanism includes a connecting frame 26 and a second ventilation pipe 20. The second ventilation pipe 20 is fixed to the connecting frame 26 and is connected to at least one upward-blowing second air outlet 21. The connecting frame 26 is located in the middle of the side walls on both sides of the first cleaning zone 5 and the second cleaning zone 6. The connecting frame 26 can move horizontally back and forth within the first cleaning zone 5 or the second cleaning zone 6 to the injection zone to blow air onto the bottom of the upper mold. Thus, as long as the second air outlet 21 enters the injection zone, air can be blown onto the bottom of the upper mold. The high-pressure air connected to the second ventilation pipe 20 can blow away the scrap material on the upper mold, thereby achieving the cleaning of the upper mold. At the same time, the reciprocating motion can greatly improve the cleaning efficiency and effect. In this invention, the specific shapes of the first air outlet 17 and the second air outlet 21 are not specifically limited, but in order to increase the blowing range, preferably, the first air outlet 17 and the second air outlet 21 are each independently a trumpet mouth."

[0004] Existing rubber injection molding machines typically require manual cleaning of the mold area using an air gun after material loading and unloading to remove flash and residual material, facilitating vacuum injection molding. Furthermore, existing rubber injection molding machines lack automated feeding mechanisms for automated operation.

[0005] The existing technology described above uses a blowing structure to clean the mold surface, which is not suitable for the mold opening diameter of various types of horizontal injection molding units, and the treatment effect is not good. It is also not suitable for dual-station operation. Utility Model Content

[0006] The purpose of this invention is to provide a dual-exit automatic high-efficiency rubber injection molding machine, which solves the problems of ordinary rubber injection molding machines not being able to operate in two stations, uncoordinated automatic feeding and unloading, and the inability to automatically clean the processing area.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a double-extrusion automatic high-efficiency rubber injection molding machine, including a rubber injection molding main body structure, a hydraulic control structure connected to the rear of the rubber injection molding main body structure, a processing operation platform structure located in the middle of the rubber injection molding main body structure, a set of automatic loading and unloading structures connected to the outside of the rubber injection molding main body structure, and a set of material preparation platform bodies also provided outside the rubber injection molding main body structure. The processing operation platform structure includes an outer side platform located in the middle of the rubber injection molding main body structure, an inner transmission channel body located in the outer side platform, and a drive transmission belt located in the inner transmission channel body.

[0008] The automatic loading and unloading structure includes a horizontal pneumatic transmission rail located on the upper part of the rubber injection molding host structure, a vertical moving rail located below the horizontal pneumatic transmission rail, and a pneumatic gripper located below the vertical moving rail.

[0009] The rubber injection molding machine structure includes a hydraulic base, a bottom support frame, a bottom drive cylinder assembly, a middle support assembly, an upper connecting seat, an upper drive cylinder assembly, and a middle vacuum cover.

[0010] The hydraulic control structure includes a supply oil tank, a multi-directional drive oil pump, and a warm oil unit.

[0011] An automatic mold-clearing mechanism is provided in the central support assembly.

[0012] The automatic mold clearing mechanism includes a set of vertical servo drive rods set in the central support assembly, a telescopic adjustment frame connected to the two vertical servo drive rods, and a set of mold clearing air nozzles set on the telescopic adjustment frame.

[0013] The upper part of the material preparation platform is equipped with a component collection tray.

[0014] The beneficial effects of this utility model are as follows: by setting up a double-exit automatic and efficient mold opening and material handling structure, the production capacity of multiple injection molding units controlled by one oil control system is greater than that of a single rubber injection molding machine in the same time. Moreover, the vulcanization waiting time of the injection molding unit is also fully utilized, eliminating or reducing ineffective working time, resulting in higher production efficiency. Furthermore, the two injection molding units share some devices, which results in lower energy consumption than two independent rubber injection molding machines.

[0015] The flash treatment of the mold forming area from the inside out removes residual adhesive residue from the lower mold parting surface, thus preventing scratches and damage to the mold parting surface. This process also removes any remaining traces of adhesive residue after detachment, completely eliminating any sticky residue. This method saves raw materials, extends mold life, shortens mold opening stroke, and improves injection molding efficiency.

[0016] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments. Attached Figure Description
