Description

Technical Field

[0001] The utility model relates to the technical field of gate valve production, in particular to an injection molding device for gate valve production. Background Art

[0002] The gate valve is a commonly used industrial valve, mainly used to control the flow and cutoff of the medium in the pipeline. The working principle of the gate valve is to change the valve opening by rotating or moving the gate up and down, thereby changing the flow of the medium. The gate valve has the advantages of simple structure, good sealing performance, large flow and small pressure loss. When producing the gate valve, it is necessary to add granular or powdered materials into the barrel of the injection molding machine through the hopper, and the plastic is molten by rotating the screw and heating the outer wall of the barrel, and then the mold is closed and the injection seat is moved forward, so that the nozzle is close to the injection port of the mold, and the fluid material is injected into the mold for molding;

[0003] After the material is poured into the hopper of the injection molding machine, when the material clumps, it is easy to cause the agglomerated material to enter the injection molding machine and fail to melt well and be injected evenly, thereby affecting the quality and surface finish of the injection molded product. It is inconvenient to disperse the material entering the barrel in the prior art.

[0004] In order to solve the above problems, the present application proposes an injection molding device for producing gate valves. Utility Model Content

[0007] A feed box is installed on the feed hopper through an elastic member, a screening agitator is installed in the feed box, and the bottom of the feed box is connected to a feed pipe extending into the feed hopper;

[0008] An eccentric vibration dispersion member extending into the feed hopper is installed at the bottom of the feed box, and the eccentric vibration dispersion member is used to drive the feed box to vibrate and beat the material discharged from the feed pipe.

[0009] Preferably, the screening agitator comprises a screening frame, the screening frame is installed in a feed box, a through material transfer channel is provided in the screening frame, a screen is installed in the material transfer channel, and a plurality of steel balls are arranged on the screen.

[0010] Preferably, the eccentric vibration dispersion component includes a cover shell and a servo motor. The cover shell is installed at the bottom of the feed box. An installation chamber is opened in the cover shell. The servo motor is installed in the installation chamber. The output end of the servo motor is connected to an eccentric wheel which is eccentrically arranged and located in the feed hopper. The outer periphery of the eccentric wheel is connected to a dispersion soft strip located below the discharge pipe.

[0011] Preferably, the elastic member includes a plurality of limit rods, and the plurality of limit rods are respectively vertically installed around the top of the feed hopper, and fixed blocks are installed around the four sides of the feed box. The plurality of fixed blocks are respectively slidably sleeved on the plurality of limit rods, and the limit rods are sleeved with a spring located between the fixed block and the feed hopper, and the two ends of the spring are respectively connected to the feed hopper and the fixed block.

[0012] Preferably, the top of the feed box is designed to be open in an inverted eight shape.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] By means of the elastic parts, feed box, screening agitation parts and eccentric vibration dispersing parts, the material can be poured into the feed box, and then the feed box can be eccentrically vibrated by the eccentric vibration dispersing parts. Under the action of the elastic parts, the feed box can be shaken up and down, and the material is screened and agitated in the screening agitation parts, so as to be dispersed. The dispersed material can enter the feed hopper through the discharge pipe. When the eccentric vibration dispersing parts are working, the material discharged from the discharge pipe can be beaten to further disperse the material. The material can enter the injection molding machine through the feed hopper. The structure can effectively prevent the material from agglomerating through the eccentric vibration dispersing parts, thereby avoiding the problem that the agglomerated material cannot be well melted and injected evenly after entering the injection molding machine.

DETAILED DESCRIPTION

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] like Figure 1-3 As shown, the utility model provides an injection molding device for producing a gate valve, comprising an injection molding machine 1 and a feed hopper 2 installed on the injection molding machine 1;

[0021] In this embodiment, a feed box 4 is installed on the feed hopper 2 through an elastic member 3. The elastic member 3 includes a plurality of limit rods 31, and the plurality of limit rods 31 are respectively vertically installed around the top of the feed hopper 2, and fixed blocks 8 are installed around the feed box 4, and the plurality of fixed blocks 8 are respectively slidably sleeved on the plurality of limit rods 31, and a spring 32 located between the fixed block 8 and the feed hopper 2 is sleeved on the limit rod 31, and the two ends of the spring 32 are respectively connected to the feed hopper 2 and the fixed block 8.

[0022] In this embodiment, a screening agitator 5 is installed in the feed box 4; the screening agitator 5 includes a screening frame 51, the screening frame 51 is installed in the feed box 4, a through material flow channel is opened in the screening frame 51, a screen 52 is installed in the material flow channel, and a plurality of steel balls 53 are arranged on the screen 52; the bottom of the feed box 4 is connected to a discharge pipe 7 extending into the feed hopper 2.

[0023] In this embodiment, an eccentric vibration dispersing member 6 extending into the feed hopper 2 is installed at the bottom of the feed box 4, and the eccentric vibration dispersing member 6 is used to drive the feed box 4 to vibrate and beat the material discharged from the discharge pipe 7. The eccentric vibration dispersing member 6 includes a cover 61 and a servo motor 62. The cover 61 is installed at the bottom of the feed box 4, and an installation chamber is opened in the cover 61. The servo motor 62 is installed in the installation chamber. The output end of the servo motor 62 is connected to an eccentric wheel 63 eccentrically arranged and located in the feed hopper 2, and the outer periphery of the eccentric wheel 63 is connected to a dispersion soft strip 64 located below the discharge pipe 7.

[0024] When it needs to be explained: In order to prevent the agglomerated material from entering the injection molding machine 1, the material can be poured into the feed box 4 so that the material is scattered on the screen 52, and then the servo motor 62 can be used to drive the eccentric wheel 63 to rotate eccentrically. Under the action of the spring 32, the feed box 4 can move up and down in the vertical direction of the limit rod 31, and the material is screened in the screen 52. When the feed box 4 is shaken, the agglomerated material can be dispersed through the mutual collision between the steel balls 53, and the dispersed material can enter the feed hopper 2 along the discharge pipe 7.

The material can enter the injection molding machine 1 along the feed hopper 2. This structure can effectively prevent the material from agglomerating through the eccentric vibration dispersion component 6, thereby avoiding the problem that the agglomerated material cannot be well melted and evenly injected after entering the injection molding machine 1.
