Description

Technical Field

[0001] The present invention relates to an injection machine, and particularly to an injection machine with a high operating rate, which is suitable for injection molding of golf ball shells. Background Art

[0002] In recent years, the number of golf players has been continuously increasing, which not only drives the growth of the golf ball shipments of various manufacturers, but also prompts the manufacturers to pay attention to the improvement of golf ball production capacity. In the production process of golf balls, the ball body is formed by injection molding with a molding die, and the fluidity of the material is related to the stability of injection molding and the product yield. Therefore, for materials with different fluidities, different dies are required for injection molding. That is to say, when the materials to be injected are different, the injection machine needs to be stopped first, and then the production line personnel need to manually replace another set of dies. In this way, not only manpower is wasted, but also the working efficiency of the machine is reduced, affecting the production capacity performance.

[0003] Therefore, how to develop a molding die that can be shared by materials with different fluidities through the improvement of die design to overcome the above defects has become one of the important issues to be solved in this industry. Summary of the Invention

[0004] The concept of the present invention is to start from the perspective of improving the die reuse efficiency and saving the die change time.

[0031] The following are specific embodiments to illustrate the implementation manners of the "injection machine with high operating efficiency" disclosed in the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. Additionally, the drawings of the present invention are only simple schematic illustrations and are not drawn according to actual sizes, which is stated in advance. The following implementation manners will further detail the related technical content of the present invention, but the disclosed content is not used to limit the protection scope of the present invention. In addition, the term "or" used herein should, depending on the actual situation, possibly include any one or a combination of more of the associated listed items.

[0032] Unless otherwise defined, the terms used herein have the same meaning as commonly understood by those skilled in the art. The materials involved in each embodiment are commercially available or prepared according to existing technologies if not otherwise specified. The operations or instruments involved in each embodiment are conventional operations or instruments in this field if not otherwise specified.

[0033] In order to keep the injection machine in stable production, reduce downtime and restart time, and improve the operating efficiency of the production line, the present invention proposes a new concept: on the basis of sharing a set of molds for materials with high fluidity and low fluidity, the number of cavities actually participating in injection molding on the mold (i.e., the variable number of cavities) is changed according to the fluidity of the injection material.

[0034] Please refer to Figure 1 and Figure 2 , and in cooperation with Figure 8 ,Figure 9 and Figure 11 As shown in Figure 9 and Figure 11 , an injection machine Z embodying the above inventive concept is provided in an embodiment of the present invention. It mainly includes a ball feeding device 1, an injection device 2, and a cutting device 3, and the ball feeding device 1, the injection device 2, and the cutting device 3 are operatively connected to each other. Among them, the ball feeding device 1 is arranged to introduce a plurality of spheres C from the outside, such as but not limited to the cores of golf balls. The injection device 2 is arranged to perform an injection molding operation on the plurality of spheres C to inject and mold a spherical shell S outside each of the plurality of spheres C, such as but not limited to a golf ball shell, and there is an injection aggregate I between the plurality of spherical shells S to connect them into one body. The cutting device 3 is arranged to perform a cutting operation on the injection aggregate I so that the plurality of spherical shells S are separated from each other and exist independently.

[0035] In actual application, the injection machine Z of the present invention may further include a first transfer device 4 and a second transfer device 5, such as but not limited to a suction cup type robotic arm. The first transfer device 4 is arranged to transfer the plurality of spheres C from the ball feeding device 1 to the injection device 2 for injection molding operation, and the second transfer device 5 is arranged to transfer the plurality of spheres C with spherical shells S from the injection device 2 to the cutting device 3 for cutting operation.

[0036] Cooperate with Figure 12 and Figure 13 As shown in Figure 12 and Figure 13 , in the present invention, the injection device 2 includes a molding die 21, which includes an upper die base 21A and a lower die base 21B, and the upper die base 21A and the lower die base 21B each include a plurality of die cavity rows R and a runner system 212. Each die cavity row R includes a plurality of die cavities 211, and the runner system 212 includes a feed runner 2121 and a plurality of supply runners 2122A connecting the feed runner 2121. It should be noted that the plurality of supply runners 2122A and the plurality of die cavity rows R are alternately arranged along the extending direction of the feed runner 2121, and the feed runner 2121 has at least one blocking position B1 for blocking the flow of injection material to the rear supply runners 2122A. More details about the runner system 212 will be further described later. Therefore, the injection device 2 can change the maximum number of injection die cavities according to the fluidity of the injection material, such as changing from 12-cavity injection to 8-cavity injection, so as to inject and mold spherical materials with high fluidity and low fluidity using a single mold. On this basis, the injection machine Z of the present invention can inject and mold materials with different fluidities without disassembling and replacing the molding die, thereby increasing the production operation rate.

[0037] Cooperate with Figure 3As shown, in an embodiment of the present invention, the goal device 1 mainly includes a plurality of goal tracks 11 and a receiving mechanism 12. The receiving mechanism 12 is disposed below the plurality of goal tracks 11 and includes a carrier base 121. Each of the plurality of goal tracks 11 has a ball-drop port 111. The carrier base 121 is configured to be movable along the extending direction of the goal track 11, and the carrier base 121 has a plurality of positioning portions 1211 to individually hold a plurality of spheres C in a predetermined position; the positioning portions 1211 can be configured in the form of grooves (such as positioning grooves) and have a shape matching a part of the sphere C. Further, the receiving mechanism 12 may further include a pair of small linear slide rails 122 and a slide block 123. The slide block 123 is disposed on the linear slide rails 122, and the bottom of the slide block 123 is cooperatively connected with the linear slide rails 122 (such as slidably connected). Also, the slide block 123 can be driven by a driver (such as a driving motor, not shown in the figure) to move the carrier base 121 along the linear slide rails 122.

[0038] In actual application, the plurality of goal tracks 11 are arranged in parallel, and the plurality of positioning portions 1211 are arranged in several columns along the extending direction of the goal track 11, and the number thereof can be greater than or equal to the number of cavity columns R, so as to facilitate simultaneously transferring a plurality of spheres C to the molding die 21 at one time, thereby improving the processing efficiency. In addition, the goal device 1 may further include a temporary storage barrel 13 to temporarily store the spheres C (golf ball cores) to be processed, and the temporary storage barrel 13 is spatially communicated with the plurality of goal tracks 11.

[0039] Cooperate with Figures 4 to 7 As shown, in an embodiment of the present invention, the injection device 2 may further include a first movable seat 22A and a second movable seat 22B. The upper mold base 21A of the molding die 21 is disposed on the first movable seat 22A, and the lower mold base 21B is disposed on the second movable seat 22B. The first movable seat 22A is configured to be movable downward along a first direction D1 toward the lower mold base 21B, and the second movable seat 22B is configured to be movable between a first receiving position and a first working position along a second direction D2; the first direction is, for example, a direction perpendicular to the ground plane, and the second direction is, for example, a direction parallel to the ground plane. When the second movable seat 22B is located at the first receiving position, the lower mold base 21B can receive a plurality of spheres C from the first transfer device 4. When the second movable seat 22B is located at the first working position, the lower mold base 21B can be clamped with the upper mold base 21A.

[0040] Furthermore, the second movable seat 22B can be arranged on a wide-width linear slide rail 23, and the bottom of the second movable seat 22B can be cooperatively connected with the linear slide rail 23 (such as slidably connected). Also, the second movable seat 22B can be driven by a driver (such as a driving motor, not shown in the figure) to drive the lower mold base 21B to move along the linear slide rail 23, that is, to move from the first receiving position to the first working position, or to move from the first working position to the first receiving position. In addition, the first movable seat 22A can be arranged between a plurality of guide posts 24 and cooperatively connected with them (such as slidably connected), and the top of the first movable seat 22A is connected to a driving member of a driver 25 (such as the telescopic member of a clamping cylinder), so that the first movable seat 22A can drive the upper mold base 21A to rise or fall along the guide posts 24 under the action of the driver 25.

[0041] In actual application, first, the second movable seat 22B is moved to the first working position to complete the positioning of the lower mold base 21B; then, the discharge head 26 of the injection device 2 is moved between the upper mold base 21A and the lower mold base 21B; subsequently, the first movable seat 22A is lowered to make the upper mold base 21A abut against the lower mold base 21B to complete the mold clamping operation of the molding die 21; finally, the discharge head 26 injects the molten material into the molding die 21 and injects it into the mold cavity 211 through the respective runner systems 212 of the upper mold base 21A and the lower mold base 21B. In addition, when the upper mold base 21A and the lower mold base 21B complete the mold clamping, the upper mold cavity 211 and the lower mold cavity 211 together form a complete circular mold cavity, so that the injected material can form a spherical shell S (such as a golf ball spherical shell) covering the sphere C in the circular mold cavity.

[0042] Cooperate Figures 6 to 11 As shown in the figure, in the embodiment of the present invention, the cutting device 3 mainly includes a stamping seat 31 and a cutting seat 32. The stamping seat 31 is arranged to be movable along the first direction D1 towards the cutting seat 32, and the stamping seat 31 has a plurality of punching heads 311. The cutting seat 32 is arranged to be movable along the third direction D3 between the second receiving position and the second working position, and the third direction D3 is perpendicular to the second direction D2; and the cutting seat 32 has a plurality of cutting blade parts 321 adapted to the plurality of punching heads 311. When the cutting seat 32 is located at the second receiving position, the cutting seat 32 can receive a plurality of spheres C with spherical shells S from the second transfer device 5, and the plurality of spheres C with spherical shells S are respectively held by the plurality of cutting blade parts 321. When the cutting seat 32 is located at the second working position, the cutting seat 32 cooperates with the stamping seat 31 to perform a cutting operation.

[0043] In actual application, the cutting blade part 321 can be arranged in the form of a tool holder and has a receiving groove to receive a part of the sphere C with the spherical shell S. In addition, a relief space corresponding to the position of the receiving groove is provided inside the punching head 311 to avoid the sphere C with the spherical shell S when impacting the cutting blade part 321.

[0044] Furthermore, the stamping seat 31 can be disposed between a plurality of guide posts 33 and cooperatively connected with them (such as slidably connected), and the top of the stamping seat 31 is connected to a driving member of a driver 34 (such as the telescopic rod member of a stamping cylinder), so that the stamping seat 31 can be pressed towards the cutting seat 32 under the action of the driver 34, and each cutting blade portion 321 is arranged to be impacted by a corresponding punching head portion 311. During the cutting operation, the stamping seat 31 is pressed against the cutting seat 32, so as to cut the ejected aggregate I (waste strip) along the mold closing line on the surface of the spherical shell S by the cooperation of the punching head portion 311 and the cutting blade portion 321. The cut ejected aggregate I then moves upward together with the punching head portion 311, and is discarded into the waste bin below after the cutting seat 32 returns from the second working position to the second receiving position. The cutting seat 32 can be disposed on a linear slide rail 35 and cooperatively connected with it (such as slidably connected), and the cutting seat 32 can be driven by a driver (such as a driving motor, not shown in the figure) to move from the second receiving position to the second working position along the linear slide rail, or move from the second working position to the second receiving position along the linear slide rail.

[0045] In the present invention, as Figure 12 shown, a plurality of cavities 211 of the upper mold base 21A or the lower mold base 21B are arranged in N cavity rows R, where N is a positive integer and N>2. The runner system 212 of the upper mold base 21A or the lower mold base 21B includes a feed runner 2121 and M supply runners 2122 connected to the feed runner 2121, where M is a positive integer and N>M≥2. The runner system 212 is specially designed, as described below. Although in Figure 1 and Figure 2 it is shown that there are twelve cavities 211 arranged in three cavity rows R, but in fact, the number of cavities can be adjusted according to requirements, so the present invention is not limited thereto.

[0046] Furthermore, the plurality of supply runners 2122 and the plurality of cavity rows R are alternately arranged along the extending direction of the feed runner 2121, and any one of the supply runners 2122 is located between two adjacent cavity rows R and communicates with at least one of them; for example, the supply runner 2122 can be designed to extend between two cavity rows R arranged vertically, and can communicate only with the cavity row R above or below it, or communicate with both the cavity row R above and below it at the same time. The feed runner 2121 has L front blocking positions B1, and any one of the front blocking positions B1 is located between two adjacent supply runners 2122 and can be set to block the flow of the ejected material to the rear supply runner 2122, where L is a positive integer and M>L≥1.

[0047] Cooperate with Figure 14As shown, in actual application, a blocking component 213 can be provided at the front-end blocking position B1 to block the communication between the feeding flow channel 2121 and the feeding flow channel 2122 behind the front-end blocking position B1, so that the injection material cannot be injected into all the cavities 211 of the cavity row R connected by the rear feeding flow channel 2122. Therefore, the molding die 21 of the present invention can change the number of cavities actually participating in the sphere molding according to the fluidity of the injection material. For example, the injection can be changed from twelve-cavity injection to eight-cavity injection to facilitate the injection molding of high-fluidity and low-fluidity injection materials with a single die. When actually applied to an injection machine, different-fluidity materials can be injection-molded without disassembling and replacing the molding die, thereby increasing the production operation rate.

[0048] In some embodiments, the blocking component 213 (such as, but not limited to, a three-way pipe fitting) may include a straight pipe portion 2131, and the setting direction of the straight pipe portion 2131 can be converted, for example, from a straight setting to a transverse setting, so as to control the on or off of the feeding flow channel 2121.

[0049] In an embodiment using a twelve-cavity mold base, if the fluidity of the material injected into the molding die 21 is relatively low, the injection material can be blocked from flowing to the four cavities 211 in the last row from the front-end blocking position B1, so as to achieve the same effect as using an eight-cavity mold base. However, the above is only a feasible embodiment and is not intended to limit the present invention.

[0050] In addition, any feeding flow channel 2122 can be connected to one of the adjacent cavity rows R through at least one diverging flow channel ( Figure 13 the first diverging flow channel 2123A and / or the second diverging flow channel 2123B shown), and at least one diverging flow channel has a rear-end adjustment position B2. Moreover, the rear-end adjustment position B2 can be set to adjust the hydrodynamic characteristics of the injection material. For example, a flow splitting component such as a flow splitting block (not shown in the figure) can be provided at the rear-end adjustment position B2 to adjust the flow rate and flow velocity of the injection material in the diverging flow channel.

[0051] In an embodiment of the present invention, any cavity row R includes a first cavity group G1 and a second cavity group G2 located on opposite sides of the feed channel 2121, and the first cavity group G1 and the second cavity group G2 have the same number of cavities. For example, four cavities 211 can be arranged in a cavity row R, where two cavities 211 form the first cavity group G1, and the other two cavities 211 form the second cavity group G2. Additionally, any feed channel 2122 includes a first side diversion section 21221 and a second side diversion section 21222, which can be formed by extending a section of the feed channel 2121 to the left and right sides; the position of the first side diversion section 21221 corresponds to the first cavity group G1, and the position of the second side diversion section 21222 corresponds to the second cavity group G2. Also, the first side diversion section 21221 is connected to one of the adjacent first cavity groups G1 through a first branch channel 2123A, and the second side diversion section 21222 is connected to one of the adjacent second cavity groups G2 through a second branch channel 2123B.

[0052] Furthermore, the first branch channel 2123A has a rear-end adjustment position B2 (the first rear-end adjustment position), and this rear-end adjustment position B2 can be set to adjust hydrodynamic characteristics such as the flow rate and flow velocity of the injected material in the first branch channel 2123A; for example, a flow splitting component can be provided at the rear-end adjustment position B2 of the first branch channel 2123A. Similarly, the second branch channel 2123B has another rear-end adjustment position B2 (the second rear-end adjustment position), and this another rear-end adjustment position B2 can be set to adjust hydrodynamic characteristics such as the flow rate and flow velocity of the injected material in the second branch channel 2123B; for example, a flow splitting component can be provided at the rear-end adjustment position B2 of the second branch channel 2123B.

[0053] Furthermore, the first branch channel 2123A includes a first upstream section 21231A and a plurality of first downstream sections 21232A. The first upstream section 21231A is connected to the first side diversion section 21221, and the plurality of first downstream sections 21232A branch out from the first upstream section 21231A and are respectively connected to a plurality of cavities 211 in one of the adjacent first cavity groups G1. Similarly, the second branch channel 2123B includes a second upstream section 21231B and a plurality of second downstream sections 21232B. The second upstream section 21231B is connected to the second side diversion section 21222, and the plurality of second downstream sections 21232B branch out from the second upstream section 21231B and are respectively connected to a plurality of cavities 211 in one of the adjacent second cavity groups G2.

Therefore, not only can the mold opening cost be reduced, but also the time for mold changing, machine adjustment and testing can be saved.
