Technical Field

[0001] The utility model relates to the technical field of cup body molds, in particular to a combined corrugated outer wall cup body mold. Background Art

[0002] At present, in the process of manufacturing plastic cups, injection molding is usually adopted, so as to complete the production of plastic cups. However, in this production and manufacturing process, especially when some specific corrugations are required on the outer side wall of the plastic cup body, the existing manufacturing of plastic cup bodies with corrugations usually has the following several problems:

[0003] First of all, since multiple groups of corrugations to be formed on the outer side wall of the plastic cup body usually need to select corresponding corrugated molds for combination into the cup outer wall during the injection molding process, which is convenient for subsequent injection molding. However, the corrugations on the cup outer wall are usually composed of multiple different corrugations combined, which requires a detachable and combinable cup body mold; secondly, the existing production molds are usually integrally formed, and it is difficult to achieve the cup body mold required for splicing according to the required corrugation combination.

[0004] Therefore, we have designed a combined corrugated outer wall cup body mold. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the corrugations on the outer wall of the cup are usually composed of multiple different corrugations combined, and the existing production molds are usually integrally formed, and it is difficult to achieve the splicing required according to the required corrugation combination, and a combined corrugated outer wall cup body mold is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

The combined outer mold includes a plurality of outer cup molds arranged in a circle and connected end to end. A transverse baffle that abuts against the outer wall of the inner cup mold is slidably arranged on the top of the outer cup mold. A pushing part for pushing the transverse baffle is arranged on the inner cup mold.

[0008] Further, the inner cup mold is cylindrical. The outer cup mold includes an arc plate and a conical plate. The conical plate is vertically fixed at the bottom of the arc plate. The outer diameter of the inner cup mold is smaller than the inner diameter of the outer cup mold.

[0009] Further, protrusions and recessed portions are respectively provided on both sides of the arc plate in the outer mold of the cup body. A corrugated groove is provided on the inner wall of the arc plate, and a sealant is provided on the side wall of the outer mold of the cup body.

Specific implementation mode

[0021] Next, in combination with the description of the drawings, the technical solutions of the present utility model will be clearly and completely described in the form of embodiments.

[0022] Refer to Figures 1 to 4 , a combined corrugated outer wall cup mold, including an inner mold 1 of the cup and an external glue filling machine. The inner mold 1 of the cup is coaxially provided with a combined outer mold. The combined outer mold includes a plurality of outer molds 5 of the cup arranged in a circle and connected end to end. Refer to Figure 1 In the state, the outer diameter of the inner mold 1 of the cup is smaller than the inner diameter of the outer mold 5 of the cup. In this way, a cup-shaped cavity is formed between the inner mold 1 of the cup and the combined outer mold, which is convenient for the external glue filling machine to inject plastic into the cavity, and finally form a plastic cup shape.

[0023] Refer to Figure 4 As shown, the outer mold 5 of the cup includes an arc plate and a conical plate. The conical plate is vertically fixed at the bottom of the arc plate. Since the side walls of the outer mold 5 of the cup are connected end to end, and protrusions 15 and recessed parts 16 are respectively provided on both sides of the arc plate in the outer mold 5 of the cup, and adjacent two outer molds 5 of the cup are snap-connected through the protrusions 15 and the recessed parts 16.

[0024] The inner wall of the arc plate is provided with a corrugated groove 14, and a sealing glue is provided on the side wall of the outer mold 5 of the cup. In this way, it is convenient to select the outer mold 5 of the cup containing different types of corrugated grooves 14 for combined splicing according to the required corrugated grooves 14, so as to achieve the cup mold required for splicing according to the required corrugated combination.

[0025] The combined outer mold also includes symmetrically arranged semi-circular snap rings 6, and positioning bolts 7 that are threadedly inserted into the semi-circular snap rings 6 and abut against the combined outer mold. In this way, by rotating the positioning bolts 7, the two semi-circular snap rings 6 can be snapped on the outer side walls of the plurality of outer molds 5 of the cup arranged in a circle, and the positioning of the plurality of outer molds 5 of the cup is completed by clamping.

[0026] The inner mold 1 of the cup is cylindrical, and a plurality of glue filling holes 2 are opened along the axis on the inner mold 1 of the cup. Under the action of the external glue filling machine, the plastic is poured into the cavity on the combined outer mold through the glue filling holes 2 on the inner mold 1 of the cup.

[0027] A transverse baffle 8 which abuts against the outer wall of the inner cup mold 1 is slidably arranged on the top of the outer cup mold 5. The transverse baffle 8 is fan-shaped, and exhaust holes 13 are formed in the transverse baffle 8. The inner diameter of the transverse baffle 8 is the same as the radius of the inner cup mold 1. In this way, it can be ensured that after the transverse baffle 8 is pushed, a plurality of transverse baffles 8 will combine to form a ring-shaped seal at the top of the cavity, completing the closure of the cup-shaped cavity. At the same time, the arrangement of the exhaust holes 13 can ensure that after the glue injection hole 2 injects into the cavity on the combined outer mold, the air in the cavity is slowly discharged by the air exhaust method, and the filling operation of the cup-shaped cavity is completed, and bubbles are prevented from being formed during the filling process.

[0028] When plastic appears in the exhaust holes 13, the injection molding operation will stop. Then, the inner cup mold 1 is driven to rotate by an external rotating device, completing the shearing effect of the plastic sprayed from the glue injection hole 2 and forming the cup mold; at the same time, when the inner cup mold 1 rotates, it can also level the filling of the cup-shaped cavity.

[0029] The pushing part further includes a fixing rod 11 fixed on the outer side wall of the outer cup mold 5. End plates 9 and bottom through plates 10 are respectively fixed on the upper and lower sides of one end of the transverse baffle 8 away from the inner cup mold 1. A through hole adapted to the fixing rod 11 is formed in the bottom through plate 10. An end block is fixed at the end of the fixing rod 11. A tension spring 12 is sleeved on the fixing rod 11, and both ends of the tension spring 12 are fixed to the end block and the bottom through plate 10 respectively. In this way, when the inclined surface 4 below the extension plate 3 abuts against the end plate 9 and drives the transverse baffle 8 to move towards the inner cup mold 1, at the same time, horizontal sliding is completed under the matching action of the fixing rod 11 and the bottom through plate 10.

[0030] A pushing part for pushing the transverse baffle 8 is arranged on the inner cup mold 1. The pushing part includes an extension plate 3 fixedly arranged in a circle on the outer side wall of the inner cup mold 1. An inclined surface 4 is arranged at the bottom of the extension plate 3, and the inclined surface 4 faces the outer side wall of the inner cup mold 1. During the downward movement of the inner cup mold 1, the extension plate 3 can be driven to descend together, and the transverse baffle 8 is pushed to move horizontally. When the transverse baffle 8 abuts against the outer side wall of the inner cup mold 1, it will no longer move horizontally, and at the same time, the downward movement of the inner cup mold 1 is stopped, providing support for forming a stable cup-shaped cavity between the inner cup mold 1 and the combined outer mold.

[0031] The working principle of the present utility model is as follows: First, the inner cup mold 1 is inserted into the combined outer mold composed of a plurality of outer cup molds 5. During the downward movement of the inner cup mold 1, the extension plate 3 can be driven to descend together, and the transverse baffle 8 is pushed to move horizontally. A plurality of transverse baffles 8 will combine to form a ring-shaped seal at the top of the cavity, completing the closure of the cup-shaped cavity. At the same time, the arrangement of the exhaust holes 13 can ensure that after the glue injection hole 2 injects into the cavity on the combined outer mold, the air in the cavity is slowly discharged by the air exhaust method, and the filling operation of the cup-shaped cavity is completed, and bubbles are prevented from being formed during the filling process.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes, modifications, substitutions, and variations can be made without departing from the gist of the present utility model.
