Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a mold with a fine water outlet that automatically drops. Background Art

[0002] In plastic molds, multiple injection points are used due to large products or optimized deformation. Fine gate injection is used to balance the flow. The traditional method of separating such gates is to separate them from the A plate through the gate hook needle and separate the pull needle from the runner through the action of the gate plate. However, due to the length of the gate sleeve, the gate is often still hung on the gate plate, so the gate must be removed by a robot or other special mechanism. In this way, the production efficiency is low. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a mold with a fine nozzle that automatically drops, so as to solve the problem in the prior art that the sleeve of the product is easy to remove but difficult to remove.

[0004] Other features and advantages of the present disclosure will become apparent from the following detailed description, or may be learned in part by the practice of the present disclosure.

[0005] The utility model discloses a mold with a fine water outlet that automatically drops, the mold comprising an A plate, a B plate and a mold core arranged between the A plate and the B plate, the A plate is provided with a panel, the gate of the mold is arranged on the panel, a pull plate is provided between the panel and the A plate, the pull plate and the A plate form a branch channel that is connected to the gate with the panel, the branch channel passes through the pull plate and the A plate and then connects to a cavity in the mold core, wherein the A plate and the B plate can move linearly relative to each other, the panel and the pull plate, the panel and the A plate can move linearly relative to each other, and when the panel and the A plate are not separated, the pull plate can be embedded in and tightly embraced on the A plate.

[0006] Furthermore, the mold further comprises a first guide rod, one end of which is fixedly connected to the panel, and the other end of which is limited in the plate A. Thus, when the panel moves the stroke of the first guide rod, it drives the plate A to move, so that the plate A and the plate B are separated from the mold.

[0007] Furthermore, the mold further comprises a second guide rod, one end of which is movably limited in the panel, and the other end of which is connected to the pull plate, and one end of the second guide rod can move linearly in the panel. Wherein, since the pull plate can be embedded in and tightly held on the A plate, when the panel starts to move, the pull plate does not move until the movement of the panel reaches the end of the movement stroke of the second guide rod, and the second guide rod pulls the pull plate to separate from the A plate, and the pull plate pulls out the nozzle material placed on it and on the A plate, so that the nozzle is separated from the product in the mold core.

[0008] Furthermore, the mold further comprises a third guide rod, the A plate and the B plate are provided with a sleeve, one end of the third guide rod is connected to the panel, and the other end thereof passes through the sleeve. Based on the third guide rod, the movement when the panel and the A plate are separated, and the A plate and the B plate are separated is smooth.

[0009] The technical solution disclosed in this disclosure has the following beneficial effects:

[0010] Based on the pull plate between the face plate and the A plate, the two-plate mold can automatically drop into the water outlet. No robot is required to take the material during the process, which reduces the production cycle time, increases output, and reduces the weight of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0017] The accompanying drawings are only schematic illustrations of the present disclosure. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted. It is understood that the proportions of the various components in the drawings do not constitute limitations of the present disclosure.

[0018] like Figure 1-3As shown, an embodiment of the present specification provides a mold with an automatically falling fine gate, wherein the mold comprises an A plate 1, a B plate 2 and a mold core 3 arranged between the A plate 1 and the B plate 2, a panel 4 is arranged on the A plate 1, a gate 5 of the mold is arranged on the panel 4, a pull plate 6 is arranged between the panel 4 and the A plate 1, a branch channel 7 connected to the gate 5 formed between the pull plate 6 and the A plate 1 is formed, the branch channel 7 passes through the pull plate 6 and the A plate 1 and is connected to the cavity in the mold core 3, wherein the A plate 1 and the B plate 2 can move linearly relative to each other, the panel 4 and the pull plate 6, the panel 4 and the A plate 1 can move linearly relative to each other, and when the panel 4 and the A plate 1 are not separated, the pull plate 6 can be embedded and tightly held on the A plate 1.

[0019] The mold further includes a first guide rod 8, one end of which is fixedly connected to the panel 4, and the other end of which is limited in the A plate 1. In this way, when the panel 4 moves the stroke of the first guide rod 8, it drives the A plate 1 to move, so that the A plate 1 and the B plate 2 are separated from the mold.

[0020] The mold further includes a second guide rod 9, one end of which is movably limited in the panel 4, and the other end of which is connected to the pull plate 6. One end of the second guide rod 9 can move linearly in the panel 4. Since the pull plate 6 can be embedded and tightly held on the A plate 1, when the panel 4 starts to move, the pull plate 6 does not move until the movement of the panel 4 reaches the end of the movement stroke of the second guide rod 9. The second guide rod 9 pulls the pull plate 6 to separate from the A plate 1, and the pull plate 6 pulls out the nozzle material placed on it and on the A plate 1, so that the nozzle is separated from the product in the mold core 3.

[0021] The mold further includes a third guide rod 10, and the A plate 1 and the B plate 2 are provided with a sleeve 11, one end of the third guide rod 10 is connected to the panel 4, and the other end thereof passes through the sleeve 11. Based on the third guide rod 10, the movement when the panel 4 and the A plate 1 are separated, and the A plate 1 and the B plate 2 are separated is smooth.

[0022] Working principle:

[0023] When the first stage of the mold is opened, the panel 4 is separated from the A plate 1. Since the pull plate 6 is tightly held in the groove of the A plate 1, one end of the second guide rod 9 first moves in the panel 4 until it moves to the end of the stroke. The panel 4 drives the second guide rod 9, and the second guide rod 9 drives the pull plate 6 to separate from the A plate 1. Then the pull plate 6 drives the diverter channel 7 (gate) to move, so that the gate is disconnected from the product in the mold core 3 cavity.

[0024] When the second section of the second mold is opened, the panel 4 continues to move, and the pull plate 6 drives the nozzle to completely separate from the A plate 1, and then the nozzle automatically falls under its own gravity.

[0025] Beneficial effects:

[0026] Based on the pull plate 6 between the panel 4 and the A plate 1, the two-plate molds can automatically drop into the water outlet. No robot is required to take materials during the process, which reduces the production cycle time, increases output, and reduces the weight of the mold.

[0027] Those skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and practicing the utility model disclosed herein. This application is intended to cover any variations, uses or adaptations of the present disclosure, which follow the general principles of the present disclosure and include common knowledge or customary technical means in the art that are not disclosed in the present disclosure.
