Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, and particularly relates to a quick demoulding structure for a bottle cap injection molding machine. Background Art

[0002] An injection molding machine, also known as an injection molding machine or an injection machine, is the main molding equipment for making various shaped plastic products by using a plastic molding die for thermoplastic or thermosetting plastics;

[0003] The demoulding structure of an injection molding machine usually adopts a split die structure of sliding separation to demould and separate a cooled and formed model part. Due to the differences caused by the cooling degree and the model part tolerance, there is usually a time difference in the demoulding time between the model part and the mold cavity under a single sliding stroke, resulting in the situation that it is necessary to extend the separation distance of the split die structure or extend the demoulding and mold closing time, which restricts the processing efficiency to a certain extent. Summary of the Utility Model

[0004] Aiming at the above technical problems existing in the prior art, a quick demoulding structure for a bottle cap injection molding machine is provided.

[0005] The purpose and efficacy of the utility model are achieved by the following specific technical means:

[0006] A quick demoulding structure for a bottle cap injection molding machine includes a lining plate part and a demoulding plate. The demoulding plate is oppositely arranged on the lining plate part. A through mold groove is formed through the lining plate part. A plurality of clamping seats are symmetrically arranged at the corners of the through mold groove. A positioning column penetrates through the clamping seat, and an electromagnetic shaft rod is slidably fitted in the positioning column;

[0007] A demoulding frame plate is arranged inside the through mold groove, and a clamping groove smaller than the groove diameter of the through mold groove is formed in the demoulding frame plate;

[0008] In the demoulding plate, sliding shaft kits are arranged at the longitudinal positions of each positioning column, and the sliding shaft kits are slidably fitted with the electromagnetic shaft rods and are electromagnetically matched with the electromagnetic shaft rods.

[0009] Further, a stepped panel extends horizontally from the clamping seat towards the mouth of the through mold groove.

[0010] Further, T-shaped embedding plates are formed at the two side edges of the lining plate part.

[0011] Further, the sliding shaft kit is a double-section sliding shaft sleeve structure.

[0012] Further, a transfer handle is inserted at the connection end of the electromagnetic shaft rod and the positioning column, and a support shaft rod is fixedly arranged between the transfer handle and the lining plate part.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] The rapid demoulding structure of the bottle cap injection molding machine can utilize the sliding shaft kit and the electromagnetic shaft rod controlled by electromagnetic to control the demoulding sliding distance between the demoulding plate and the lining plate part during the mold opening process, so that in the demoulding state, through the sliding position of the lining plate part, the through mold groove and the demoulding frame plate are used to contact the model part in the mold cavity, and the separation of the model part and the mold cavity is assisted through the sliding process, so as to improve the demoulding efficiency and stability of the injection molding machine.

Detailed Embodiment

[0023] Please refer to Figures 1-4 , for further description of the embodiments of the utility model;

[0024] A rapid demoulding structure of a bottle cap injection molding machine includes a lining plate part 1 and a demoulding plate 2. The demoulding plate 2 is oppositely arranged on the lining plate part 1. A through mold groove 3 is formed through the lining plate part 1. A plurality of card seats 4 are symmetrically arranged at the corners of the through mold groove 3. A positioning column 5 is arranged through the card seat 4, and an electromagnetic shaft rod 8 is slidably fitted in the positioning column 5;

[0025] A demoulding frame plate 7 is arranged inside the through mold groove 3, and a card slot smaller than the groove diameter of the through mold groove 3 is formed in the demoulding frame plate 7;

[0026] In the demoulding plate 2, matching sliding shaft kits 6 are provided at the longitudinal positions of each positioning post 5. The sliding shaft kits 6 are in sliding fit with the electromagnetic shaft rod 8 and are electromagnetically coupled with the electromagnetic shaft rod 8.

[0027] In this structure, the lining plate 1 is used as the sleeve end of the cavity opening of the die cavity structure of the mold, so that its through mold groove 3 communicates with the die cavity. The groove shape of the through mold groove 3 and the distribution of the clamping seats 4 are determined according to the die cavity structure. The structure of the demoulding plate 2 is correspondingly arranged on the demoulding template of the injection molding machine, and the position of the electromagnetic shaft rod 8 and the sliding shaft kit 6 is coordinated to match the demoulding and mold closing processes of the mold.

[0028] At the same time, as shown in Figure 2 and 3 , when the lining plate 1 and the demoulding plate 2 are separated and combined, the longitudinal position of the lining plate 1 changes along with that of the demoulding plate 2. When the mold is removed from the die cavity, the slot structure of the demoulding frame plate 7 is used to contact the edge of the model part. Thus, when the position of the demoulding frame plate 7 changes, the model part can be driven to slide out of the die cavity through the structure of the demoulding frame plate 7, so that the model part can quickly separate from the die cavity and the demoulding frame plate 7 by its own weight, completing the rapid demoulding of the structure.

[0029] Compared with the traditional demoulding structure, this structure coordinates with the electromagnetic-controlled sliding structure to adjust the sliding stroke of the demoulding plate 2 and the lining plate 1. Furthermore, when the mold is in the demoulding state, the internal structure of the positioning post 5 slides after being electrified by the electromagnetic field to assist the demoulding of the model part, improving the demoulding efficiency and stability of this structure.

[0030] Preferably, the clamping seat 4 extends horizontally towards the notch of the through mold groove 3 to form a stepped panel. The protruding stepped panel can match the notch structure of the through mold groove 3 to match the outer edge of the model part, so as to cooperate with the demoulding frame plate 7 structure with a relatively small groove diameter to be clamped with the outer edge of the model part from large to small, improving the accuracy of the entire demoulding frame plate 7 structure during the process of clamping with the edge of the model part.

[0031] Preferably, T-shaped inlay panels are formed on both side edges of the lining plate 1. The lining plate 1 uses the inlay panel structure formed on the outside to be embedded on the surface of the die cavity of the mold, improving the positioning accuracy of the lining plate 1 structure in the longitudinal position of the notch.

[0032] Preferably, the sliding shaft kit 6 is a two-section sliding shaft sleeve structure. When the battery shaft rod 8 and the end of the sliding shaft kit 6 are electrified, the two-section sliding shaft sleeve structure can use the relatively fast to slow sliding rate of the sliding shaft kit 6 to ensure the safety during the mold closing process of the lining plate 1 and the demoulding plate 2.

[0033] Preferably, a transfer handle 12 is inserted at the connection end of the electromagnetic shaft rod 8 and the positioning post 5, and a support shaft rod 9 is fixedly arranged between the transfer handle 12 and the lining plate member 1. The support shaft rod 9 and the transfer handle 12 serve as an extended fixed structure from the electromagnetic shaft rod 8 to the lining plate member 1 and the inner end of the mold cavity to control the maximum telescopic limit position of the electromagnetic shaft rod 8, and at the same time, the axial structural strength of the electromagnetic shaft rod 8 is enhanced by using the structure of the support shaft rod 9.

[0034] Preferably, a spring shaft 13 is inserted between the transfer handle 12 and the electromagnetic shaft rod 8. Further, the telescopic process of the battery shaft rod 8 when it extends and retracts to the inner end limit position of the lining plate member 1 is buffered by the spring shaft 13, so as to limit the telescopic rate through the elastic damping provided by the spring shaft 13 and ensure the safety of the sliding structure of the electromagnetic shaft rod 8.

[0035] Preferably, a side support handle 11 is sleeved on the transfer handle 12, and the side support handle 11 is fixedly connected to the demolding frame plate 7. The side support handle 11 fixes the demolding frame plate 7 on the transfer handle 12, thereby improving the fixing strength of the transverse structure of the demolding frame plate 7.

[0036] Preferably, a column 10 is arranged through between the bottom of the support shaft rod 9 and the lining plate member 1. Further, the connection ends of the support shaft rod 9, the lining plate member 1 and the transfer handle 12 are axially strengthened by the extended column 10 structure.

[0037] The implementation mode of the device is as follows:

[0038] In this structure, the lining plate member 1 is used as the sleeve end of the mold cavity opening of the mold cavity structure, so that its through mold groove 3 communicates with the mold cavity. Then, the demolding plate 2 structure is correspondingly arranged on the demolding template of the injection molding machine. When the mold is closed, the sliding structures of the electromagnetic shaft rod 8 and the sliding shaft kit 6 can cooperate with the closing of the mold for synchronous sliding displacement, as Figure 2 shown. Then, during the mold opening and the demolding process of the model part, the position of the demolding plate 2 is adjusted with the sliding of the demolding template of the injection molding machine. Then, the attraction generated after the electromagnetic shaft rod 8 and the end of the sliding shaft kit 6 are electrified is used to make the end of the electromagnetic shaft rod 8 extend and retract along the sliding shaft kit 6 until it moves to as Figure 3 shown. During the process, the model part is driven to separate from the mold cavity by the sliding of the entire lining plate member 1 along the positioning post 5 through the clamping of the through mold groove 3 and the edge of the demolding frame plate 7 and the edge of the model part, thereby assisting the model part to be quickly demolded, so that the model part can quickly separate from the mold cavity and the demolding frame plate 7 by its own weight subsequently.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
