Description

Technical Field

[0001] The utility model relates to the technical field of mold opening, in particular to a turnover type mold opening mechanism for a mold. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material, and is known as the "mother of industry".

[0003] The most common mold structure is generally composed of an upper mold and a lower mold. The product is shaped through the cavity between the two. After the product is shaped, the upper mold is opened by the mold opening mechanism, and then the product is taken out from the lower mold. At present, the vertical mold opening method is widely used in the industry, such as the mold opening mechanism of a mold disclosed in patent CN220700262U, and the alloy component casting mold opening equipment disclosed in patent CN220698225U, which are all such structures. When opening the mold, the upper mold is lifted upward by a cylinder or an electric push rod to achieve the separation of the upper and lower molds, but this mold opening method has a disadvantage: the distance that the upper mold is lifted is limited. After the mold is opened, the upper mold and the lower mold are still in the same vertical space. Therefore, in the process of taking out the product from the lower mold, the upper mold will cause certain interference (including interference in sight and interference in action). If this interference is to be avoided, the distance that the upper mold is lifted can only be increased, but this requires the stroke of the cylinder or electric push rod, and requires a larger cylinder or electric push rod, which makes the overall volume of the equipment larger and the cost increases.

[0004] In summary, the existing mold opening method needs to be improved. Utility Model Content

[0005] In order to solve the above technical problems, the utility model discloses a flip mold opening mechanism for a mold, comprising a base, a driving unit, a rack, a gear, a flip bracket and a clamping arm cylinder, wherein the driving unit is arranged on one side of the base and is fixedly connected to one end of the rack through a connecting block, the bottom of the rack is slidably connected to a slide rail arranged on the base, the gear and the rack are meshed for transmission, the flip bracket is arranged on the other side of the slide rail, a flip shaft is horizontally provided on the flip bracket, one end of the flip shaft is coaxially connected to the gear, and the rear end of the clamping arm cylinder is arranged on the flip shaft through a flip block.

[0006] Furthermore, a positioning platform for placing the mold is provided on one side of the base at a position in front of the flip bracket and the flip cylinder.

[0007] Furthermore, a lifting platform for placing the mold is provided on one side of the base in front of the flip bracket and the flip cylinder, a fixed seat is provided at the bottom of the lifting platform, and a lifting cylinder is provided between the lifting platform and the fixed seat.

[0008] Furthermore, a telescopic rod is provided on each side of the lifting cylinder, and the upper and lower ends of the telescopic rod are respectively connected to the lifting platform and the fixing seat.

[0009] Furthermore, a T-shaped block adapted to the two clamping arms of the clamping arm cylinder is provided on the top of the upper mold of the mold.

[0010] Furthermore, a support plate is provided at the bottom of each side of the base.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The flip mold opening mechanism of the utility model drives the rack to move through the driving unit, and drives the gear to rotate through the rack, thereby driving the flip shaft and the clamp arm cylinder to perform flipping movement, thereby realizing the flip mold opening of the upper mold. After the upper mold is flipped, it is not in the same vertical space as the lower mold, so it will not affect the removal of the product from the lower mold. While ensuring that the overall volume of the mechanism is small, the efficiency of mold opening and product removal is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] Embodiment 1:

[0022] like Figure 1 As shown, the flip mold opening mechanism for the mold in this embodiment includes a base 1, a driving unit 2, a rack 3, a gear 4, a flip bracket 5 and a clamping arm cylinder 6. The driving unit 2 is arranged on one side of the base 1 and is fixedly connected to one end of the rack 3 through a connecting block 7. The bottom of the rack 3 is slidably connected to a slide rail 8 arranged on the base 1, and the gear 3 and the rack 4 are meshed for transmission.

[0023] The driving unit 2 may adopt a linear driving method used in the art, such as an air cylinder, an oil cylinder, a linear module, etc.

[0024] The flip bracket 5 is arranged on the other side of the slide rail 8 , and a flip shaft 9 is arranged on the flip bracket 5 in the transverse direction. One end of the flip shaft 9 is coaxially connected to the gear 4 , and the rear end of the clamp arm cylinder 6 is arranged on the flip shaft 9 through a flip block 10 .

[0025] A support plate 11 is provided at the bottom of both sides of the base 1 for supporting and fixing the base 1 .

[0026] A positioning table 12 for placing the mold is also provided on one side of the base 1 at a position in front of the flip bracket 5 and the flip cylinder 6 .

[0027] A T-shaped block 14 matching the two clamping arms of the clamping arm cylinder 6 is provided on the top of the upper die 13 of the mold.

[0028] When in use, the entire mold is placed on the positioning table 12. In the initial state, the clamp arm cylinder 6 is in a horizontal state; the clamp arm cylinder 6 moves first, clamping the T-block 14 through the clamp arms on both sides, and then the driving unit 2 drives the rack 3 to move forward, and further drives the gear 4 to rotate counterclockwise, thereby driving the flip shaft 9 and the clamp arm cylinder 6 to flip upward, and opening the upper mold 13 from the lower mold 15.

[0029] The stroke of the driving unit 2 can ensure that the upward turning angle of the clamp arm cylinder 6 is ≥90°. After opening, the upper mold 13 and the lower mold 15 are not in the same vertical space, so it will not affect the removal of the product from the lower mold 15.

[0030] Embodiment 2:

[0031] The mold opening mechanism of the above embodiment is suitable for the situation where the upper mold 13 and the lower mold 15 are not specially positioned. If the upper mold 13 and the lower mold 15 are provided with positioning structures such as positioning columns, the mold cannot be opened by directly turning it over, which will cause damage to the mold.

[0032] Therefore, in order to further improve the mold opening effect, Figure 2 As shown, a lifting platform 16 for placing the mold is also provided on the front side of the base 1, a fixed seat 17 is provided at the bottom of the lifting platform 16, a lifting cylinder 18 is provided between the lifting platform 16 and the fixed seat 17, a telescopic rod 19 is provided on each side of the lifting cylinder 18, and the upper and lower ends of the telescopic rod 19 are respectively connected to the lifting platform 16 and the fixed seat 17; wherein, the telescopic rod 19 can adopt a gas spring or a hydraulic rod.

[0033] When in use, the entire mold is placed on the lifting platform 16. In the initial state, the clamping arm cylinder 6 is in a horizontal state; the clamping arm cylinder 6 moves first, clamping the T-block 14 through the clamping arms on both sides, and then the lifting cylinder 18 moves again, driving the lifting platform 16 to drop a certain distance, so that the upper mold 13 is separated from the positioning structure; then the driving unit 2 drives the rack 3 to move forward, and further drives the gear 4 to rotate counterclockwise, thereby driving the flip shaft 9 and the clamping arm cylinder 6 to flip upward, and opening the upper mold 13 from the lower mold 15.

[0034] Through the above two implementation modes, the utility model can meet the mold opening requirements of both molds with and without positioning structures, thereby improving the versatility and practicality of the mechanism. Compared with the traditional vertical mold opening method, the mold opening and product removal efficiency is improved while ensuring that the overall volume of the mechanism is small and the cost is low.

[0035] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
