[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] Reference Figure 1-4 As shown, a valve core molding device includes a first mold 1 and a second mold 2, wherein a first cavity 14 and a second cavity 15 are respectively arranged at corresponding positions on the first mold 1 and the second mold 2, and a movable component that can move laterally is arranged on the first mold 1; first grooves 13 and second grooves 12 that penetrate laterally are respectively arranged at corresponding positions on the first cavity 14 and the second cavity 15, and the first grooves 13 and the second grooves 12 are combined to form a through hole, and an insertion rod 8 is arranged at a position corresponding to the through hole on the movable component, and the insertion rod 8 cooperates with the movable component to insert or pull out the first cavity 14 and the second cavity 15 from the through hole, and an injection channel 66 connected to the first cavity 14 or the second cavity 15 is arranged on the first mold 1 or the second mold 2.

[0022] In this embodiment, when the device is used, the material enters the first cavity 14 and the second cavity 15 through the injection channel 66 provided on the second mold 2. The first cavity 14 and the second cavity 15 are provided with a first groove 13 and a second groove 12 which penetrate laterally at corresponding positions, respectively. The first groove 13 and the second groove 12 are provided in a semicircular shape, and the first groove 13 and the second groove 12 are combined to form a circular through hole. The first mold 1 is provided with a movable component which can move laterally. The movable component can be a hydraulic cylinder, and the movable state of the movable component is controlled by controlling the hydraulic cylinder. The movable component is provided with an insertion rod 8 at a position corresponding to the through hole. The insertion rod 8 cooperates with the movable component to insert or pull out the first cavity 14 and the second cavity 15 from the through hole. According to the requirements of different molds, the insertion rod 8 is provided with a thick rod and a thin rod, and the thick rod and the thin rod are arranged alternately and matched with the through hole, so as to help the mold to form a specific state to control the molding and demolding of the mold.

[0023] Furthermore, the first mold 1 and the second mold 2 are both provided with a flow channel 10 connected to the injection channel 66 for material flow, and the number of the first cavity 14 and the second cavity 15 is multiple and evenly distributed on both sides of the flow channel 10; the number of the movable components is two, and they are respectively located on both sides of the corresponding flow channel 10 on the first mold 1.

[0024] In this embodiment, multiple first cavities 14 and second cavities 15 are provided to improve the production efficiency of the overall device. Because the fluidity of different materials is different, the first cavity 14 and the second cavity 15 are provided on both sides of the flow channel 10 to enable the material to flow accurately to the specified position, especially the fluidity of CPVC material is relatively high. Through the arrangement of this solution, as many products as possible can be molded.

[0025] More preferably, the movable component includes a movable seat and an inclined hole 6 arranged on a movable plate, and the insertion rod 8 is arranged at one end of the movable seat corresponding to the through hole; an inclined rod 3 is installed on the second mold 2, and the inclined rod 3 is inserted into the inclined hole 6, and when the second mold 2 moves, the movable seat is driven to move laterally on the first mold 1 through the cooperation of the inclined rod 3 and the inclined hole 6.

[0026] The movable component is driven to move laterally through the cooperation of the inclined rod 3 and the inclined hole 6. When the second mold 2 is opened, the inclined rod 3 drives the movable seat to move through the inclined hole 6, and brings the insertion rod 8 out of the first cavity 14 and the second cavity 15, thereby completing the demolding. This setting allows the device to drive the movable component without external force, reduces the cost of use, and improves production efficiency.

[0027] Furthermore, a guide hole 9 is provided on the first mold 1 at a position corresponding to the inclined rod 3 , and the inclined rod 3 extends into the guide hole 9 after passing through the inclined hole 6 , and the width of the guide hole 9 is adapted to the radial dimension of the inclined rod 3 .

[0028] The guide hole 9 can help the inclined rod 3 to move better, and the width is adapted to the radial size of the inclined rod 3 and can also limit the inclined rod 3 to ensure that the inclined rod 3 does not shake.

[0029] Furthermore, the movable seat includes a first movable plate 5 and a second movable plate 4, the inclined hole 6 is located on the first movable plate 5, the insertion rod 8 is located on the second movable plate 4, and the first movable plate 5 and the second movable plate 4 are detachably connected.

[0030] During the use of the overall device, the first movable plate 5 and the second movable plate 4 will experience a certain degree of wear and tear, and parts need to be replaced. The disassembly connection can be used to replace parts according to the worn parts, thereby reducing maintenance costs.

[0031] Furthermore, the first movable plate 5 and the second movable plate 4 are both provided with slots at corresponding positions, and an I-shaped connector 7 is detachably installed in the slots. The slots on the first movable plate 5 and the second movable plate 4 are combined to have a shape that matches the I-shaped connector 7, and the first movable plate 5 and the second movable plate 4 are laterally fixed by the I-shaped connector 7. A plurality of I-shaped connectors 7 can be provided, and this arrangement can reinforce the connection between the first movable plate 5 and the second movable plate 4, preventing the first movable plate 5 and the second movable plate 4 from losing connection, thereby hindering demoulding of the device.

[0032] Furthermore, the first movable plate 5 and the second movable plate 4 are both provided with convex edges on the side, and the first mold 1 is provided with a third groove 11 at a position corresponding to the convex edge, and the first movable plate 5 and the second movable plate 4 can be installed on the first mold 1 in a laterally movable manner through the convex edge and the third groove 11. This arrangement can limit the first movable plate 5 and the second movable plate 4 to prevent the first movable plate 5 and the second movable plate 4 from shaking, thereby affecting the use of the device.
