Description

Technical Field

[0001] The utility model relates to the technical field of casting moulds, in particular to a recyclable high-precision mechanical casting mould. Background Art

[0002] A casting mold is a material that is made of other easily formed materials in advance in order to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part structure. A flowing liquid is then poured into the cavity. After the liquid cools and solidifies, it can form a part with the same shape and structure as the mold, and can be recycled.

[0003] The prior art proposes a Chinese patent with a publication number of CN218855552U. The technical solution disclosed in the patent document is as follows: a recyclable high-precision mechanical casting mold, wherein the upper end of the base is provided with a demoulding device, and the demoulding device includes a first electric telescopic rod, and the outer wall of the first electric telescopic rod is fixedly connected to the base. The outer wall of the round rod on the left membrane is inserted into the inner wall of the right membrane, so that the outer wall of the left membrane and the right membrane are completely fitted, and the raw materials inside the left and right membranes are poured in, the cover on the water pipe port on the surface of the pressing module is unscrewed, and the external water pipe is connected to allow cold water to be injected into the inner wall of the pressing module. The motor drives the fan blade to rotate, so that the external air enters the box through the filter on the air inlet, and the heat generated by the inner wall of the left and right membranes contacting the raw materials enters the box and is discharged from the air outlet. The temperature of the outer wall of the pressing module and the temperature of the fan blades to discharge the temperature inside the box are used to greatly improve the efficiency of automatic recyclable demoulding.

[0004] Although the prior art utilizes the combination of water cooling and air cooling to improve the efficiency of automatic cyclic demolding, when the left and right molds are moved away from each other for mold opening, the internal casting is separated from the inner walls of the left and right molds after cooling and may fall from the gap between the two, posing certain safety hazards and causing damage to the casting. Utility Model Content

[0005] The purpose of the utility model is to provide a high-precision mechanical casting mold which can be recycled to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A recyclable high-precision mechanical casting mold comprises a reinforced base, an upper mold, a left mold, a right mold and a downward hydraulic rod. Both sides of the left mold and the right mold are provided with mold opening components for opening the molds.

[0008] The mold opening assembly includes a reinforcing cross frame fitted with the outer wall of the right mold, a supporting rod supporting the reinforcing cross frame, a built-in hydraulic rod located inside the reinforcing cross frame for driving the right mold to open the mold, and a connecting rod fixedly connected to one end of the built-in hydraulic rod, a built-in receiving plate is movably connected to the bottom of the inner wall of the left mold and the right mold, a spring return rod is fixedly connected to the center of the bottom surface of the built-in receiving plate, and one end of the connecting rod is rotatably connected to one side of the right mold.

[0013] The above-mentioned technical solution is adopted. In this solution, the spring return rod at the bottom of the built-in receiving plate elastically pulls it, so that when the left mold and the right mold are docked, the built-in receiving plate can be pulled by the spring return rod to fit tightly with the bottom of the inner wall of both without leaving any gap, thereby ensuring the subsequent processing of the casting.

[0014] A further improvement of the technical solution of the utility model is that: the bottom end of the spring return rod is fixedly connected to the upper surface of the reinforcement base, and the bottom end of the support rod is fixedly connected to the upper surface of the reinforcement base.

[0015] A further improvement of the technical solution of the utility model is that the upper mold is located above the left mold and the right mold.

[0016] A further improvement of the technical solution of the utility model is that the bottom surfaces of the left mold and the right mold are not in contact with the upper surface of the reinforcement base.

[0017] A further improvement of the technical solution of the utility model is that the upper surface of the upper mold is fixedly connected to the bottom end of the downward hydraulic rod.

[0018] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0019] 1. The utility model provides a recyclable high-precision mechanical casting mold. By using the connecting rod, the guide transverse groove, the built-in hydraulic rod and the flip hydraulic rod in the mold opening assembly, the left mold and the right mold can be flipped after the mold is opened by translation from left to right, and the casting on the built-in receiving plate can be driven to move up, thereby facilitating the removal of the casting. At the same time, the built-in receiving plate is used to lift the casting to avoid the problem of falling.

[0020] 2. The utility model provides a recyclable high-precision mechanical casting mold, which utilizes the elastic traction of the spring return rod at the bottom of the built-in receiving plate, so that when the left mold and the right mold are docked, the built-in receiving plate can be pulled by the spring return rod to fit tightly with the bottom of the inner wall of the two without leaving a gap, thereby ensuring the subsequent processing of the casting.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention is further described in detail below in conjunction with the embodiments:

[0029] Example 1

[0030] like Figure 1-5 As shown, the utility model provides a recyclable high-precision mechanical casting mold, including a reinforced base 1, an upper mold 2, a left mold 3, a right mold 4 and a downward hydraulic rod 5, and both sides of the left mold 3 and the right mold 4 are provided with a mold opening component 6 for opening the mold.

[0031] The mold opening assembly 6 includes a reinforcing cross frame 9 that is in contact with the outer wall of the right mold 4, a supporting rod 10 that supports the reinforcing cross frame 9, a built-in hydraulic rod 12 located inside the reinforcing cross frame 9 that drives the right mold 4 to open the mold, and a connecting rod 13 that is fixedly connected to one end of the built-in hydraulic rod 12. The bottom of the inner wall of the left mold 3 and the right mold 4 is movably connected with a built-in receiving plate 7, and a spring return rod 8 is fixedly connected at the center of the bottom surface of the built-in receiving plate 7. One end of the connecting rod 13 is rotatably connected to one side of the right mold 4.

[0032] A guide groove 11 for guiding and limiting the connecting rod 13 is provided on one side of the reinforcement cross frame 9. A flip hydraulic rod 14 is rotatably connected to the bottom surface of the reinforcement cross frame 9 through an axle seat. The flip hydraulic rod 14 is rotatably connected to an axle rod at one end away from the reinforcement cross frame 9.

[0033] One end of the shaft rod is fixedly connected to one side of the right mold 4 , and the bottom surface of one end of the reinforcement cross frame 9 is fixedly connected to the top end of the support rod 10 .

[0034] The bottom of the inner wall of the left mold 3 and the right mold 4 are both provided with an arc groove for adapting the spring return rod 8. The inner wall of the arc groove is movably connected to the outer wall of the spring return rod 8. The spring return rod 8 at the bottom of the built-in receiving plate 7 is elastically pulled by it, so that when the left mold 3 and the right mold 4 are docked, the built-in receiving plate 7 can be pulled by the spring return rod 8 to fit tightly with the bottom of the inner wall of the two without leaving a gap, thereby ensuring the subsequent processing of the casting.

[0035] The bottom end of the spring return rod 8 is fixedly connected to the upper surface of the reinforcement base 1 , and the bottom end of the support rod 10 is fixedly connected to the upper surface of the reinforcement base 1 .

[0036] After the casting is taken out, the left mold 3 and the right mold 4 begin to reset under the action of the mold opening assembly 6, and the built-in receiving plate 7 will be pulled back by the spring reset rod 8 to fit and seal with the bottom of the inner wall of the left mold 3 and the right mold 4 again.

[0037] Example 2

[0038] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the upper mold 2 is located above the left mold 3 and the right mold 4, the bottom surfaces of the left mold 3 and the right mold 4 do not contact the upper surface of the reinforced base 1, and the upper surface of the upper mold 2 is fixedly connected to the bottom end of the downward hydraulic rod 5.

[0039] The following is a detailed description of the working principle of the recyclable high-precision mechanical casting mold.

[0040] like Figure 1-5 As shown, when the casting is cooled and needs to be taken out, the built-in hydraulic rod 12 is started to pull the connecting rod 13 to move right along the inner wall of the guide transverse groove 11, and at the same time drive the right mold 4 to move to the right. At this time, the flipping hydraulic rod 14 contracts synchronously, and when the right mold 4 is translated to a suitable position, the flipping hydraulic rod 14 will push the shaft rod to drive the right mold 4 to deflect with the connecting rod 13 as the axis, and the left mold 3 and the right mold 4 are synchronized. When the left mold 3 and the right mold 4 are deflected, the bottom of the inner wall of both will contact the bottom surface of the built-in receiving tray 7 and push the built-in receiving tray 7 to move up. At this time, the casting located on the upper surface of the built-in receiving tray 7 will move up accordingly, and then the casting can be quickly and conveniently taken out.

[0041] After the casting is taken out, the left mold 3 and the right mold 4 begin to reset under the action of the mold opening assembly 6, and the built-in receiving plate 7 will be pulled back by the spring reset rod 8 to fit and seal with the bottom of the inner wall of the left mold 3 and the right mold 4 again.

[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
