DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: an injection molding device with a batch processing function, comprising a support base 1 and a rotating table 4, the support base 1 is connected with a movable support frame 2, the movable support frame 2 and the support base 1 are connected with an injection molding assembly 3, the rotating table 4 is connected with a movable mold device 5, the position of the movable mold device 5 corresponds to the position of the injection molding assembly 3, the movable mold device 5 is connected to the support base 1, and a rotating drive device 6 is connected under the rotating table 4, and the rotating drive device 6 is connected to the support base 1;

[0021] A rotating table 4 is used to adjust the movable mold device 5 to different positions. The injection molding component 3 is used to heat the raw material and inject the molten raw material into the mold. The movable support frame 2 is composed of a bracket and an electric hydraulic rod, which can control the height change of the injection molding component 3 and adjust its position to the corresponding mold.

[0022] The movable mold device 5 includes a supporting cylinder 51, four lower molds 54 and four upper molds 55. The lower mold 54 is connected to the rotating table 4. Two telescopic rods 57 are connected to the side of the upper mold 55. The telescopic rod 57 is connected to the rotating table 4. The upper mold 55 is connected to a guide rod 56 on the side close to the supporting cylinder 51. A guide groove 53 is opened on the side of the supporting cylinder 51, and the guide rod 56 is slidably arranged in the guide groove 53.

[0023] A telescopic rod 57 is used to guide the movement of the upper mold 55, so that the upper mold 55 can move stably in the vertical direction when being squeezed by the outside, so that the mold opening and closing operations between the upper mold 55 and the lower mold 54 are accurate and stable;

[0024] A guide rod 56 and a guide groove 53 are used. The guide groove 53 is composed of two horizontal arc sections and two inclined sections. When the guide rod 56 rotates along the guide groove 53, it will be squeezed by the convex part of the guide groove 53 to move upward, thereby controlling the upward movement of the upper mold 55.

[0025] The guide rod 56 is set to be cylindrical, the rotating table 4 is set to be circular, the positions of the upper mold 55 and the lower mold 54 correspond to the position of the injection molding component 3, and the guide rod 56 is set to be cylindrical, so that it can be squeezed and tilted when rotating in the guide groove 53, making the movement smoother.

[0026] A fixing rod 52 is connected to the support tube 51 below, and the bottom end of the fixing rod 52 is connected to the support seat 1. The fixing rod 52 passes through the rotation drive device 6 and the rotating table 4. An injection hole is opened on the upper mold 55, and the support tube 51 coincides with the center of the rotating table 4.

[0027] A fixing rod 52 is used to keep it fixed on the support base 1, and when the rotating platform 4 rotates, it can form a relative rotation process with it;

[0028] The rotary drive device 6 comprises a connecting tube 61 , a bearing 62 is provided on the outer sleeve of the connecting tube 61 , the bearing 62 is provided on the support seat 1 , a first rotating disk 63 is connected to the outside of the connecting tube 61 , and an extrusion groove 64 is provided on the outside of the first rotating disk 63 .

[0029] The connecting tube 61 and the bearing 62 are used to support the rotating platform 4, and the fixing rod 52 is convenient to pass downward through the connecting tube 61 and connect with the supporting seat 1, so as to ensure the smooth and stable rotation of the rotating platform 4;

[0030] A second turntable 65 is rotatably disposed outside the first turntable 63 . An extended extrusion column 67 is connected to the second turntable 65 . A driving assembly 66 is connected below the second turntable 65 . The driving assembly 66 is connected to the support seat 1 .

[0031] An extended extrusion column 67 and an extrusion groove 64 are used. During the rotation of the extended extrusion column 67, the extended extrusion column 67 will intermittently enter the extrusion groove 64 to control the intermittent rotation of the first turntable 63 and the rotating table 4. The driving component 66 is used to control the rotation of the second turntable 65. When the second turntable 65 contacts the first turntable 63, the first turntable 63 is limited to prevent the first turntable 63 from rotating at will.

[0032] The working principle of the utility model is:

[0033] When injection molding is required, the drive assembly 66 is directly controlled to work. When the drive assembly 66 is working, the second turntable 65 is controlled to rotate, and the extended extrusion column 67 is rotated into the extrusion groove 64 and the first turntable 63 is controlled to rotate. When the first turntable 63 rotates, the connecting cylinder 61 and the rotating table 4 are controlled to rotate. After the lower mold 54 and the upper mold 55 at the front side are rotated to the right to the position directly below the injection molding assembly 3, the extended extrusion column 67 is separated from the extrusion groove 64, and the guide rod 56 is squeezed and moved downward by the guide groove 53. The guide rod 56 and the upper mold 55 move downward and contact with the lower mold 54 to complete the mold closing. Subsequently, the injection molding assembly 3 works to inject the raw material into the cavity between the upper mold 55 and the lower mold 54. When the injection molding is completed, the injection molding assembly 3 is controlled to stop working. At this time, the extended extrusion column 67 enters the extrusion groove 64 again. At this time, the upper mold 55 and the lower mold 54 after the injection molding are completed rotate backward away from the injection molding assembly 3, and different upper molds 55 and lower molds 54 can be intermittently injected to achieve continuous injection molding operation.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
