Description

Technical Field

[0001] The utility model relates to an oblique insertion type guide component for a mold, belonging to the technical field of mechanical processing equipment. Background Art

[0002] The mold guide assembly plays the role of positioning, guiding, and bearing a certain lateral pressure during mold operation, ensuring that the upper and lower parts of the mold can be accurately aligned and open and close smoothly. Existing molds are usually achieved through the cooperation of guide pins and guide sleeves, but there is a certain elastic gap in the connection between the guide pins and guide sleeves, resulting in low rigidity and cooperation accuracy, and the stamping load that can be carried is also small. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an oblique insertion guide component for a mold, which has high matching accuracy and small load per unit contact area, can ensure accuracy and stability under high-load stamping, and can solve the shortcomings of the prior art.

[0004] The technical solution of the utility model is: an oblique insertion guide component for a mold, comprising four groups of guide components arranged on an upper mold and a lower mold for paired use, the guide components comprising a convex part fixed on the upper mold and a concave part fixed on the lower mold, the convex part has a vertical contact outer wall, the concave part has a groove, the groove has a matching vertical contact inner wall, the convex part and the concave part are slidingly matched through vertical surface contact, and the four groups of guide components are obliquely arranged and distributed in a rhombus shape on the upper mold and the lower mold.

[0005] Furthermore, the top of the convex part and the opening edge of the groove of the concave part are rounded or chamfered.

[0006] It further includes a refueling device, which includes an oil supply pipeline. An oil storage tank is provided on the contact outer wall of the convex part, and an oil supply channel connected to the oil storage tank is provided in the convex part. The oil supply pipeline is installed on the convex part and communicated with the oil supply channel in the convex part.

[0007] Further, the protrusion has a base portion, the groove is located above the base portion, and an oil guide groove is provided on the base portion.

[0008] Furthermore, the oil guide groove is arranged obliquely and is located on both sides of the groove.

[0009] Through the implementation of the utility model, the convex and concave parts of the guide assembly are slidably connected through vertical direct contact surface sealing cooperation. Compared with the traditional guide column and guide sleeve cooperation, the surface contact sliding cooperation has the characteristics of high rigidity and small load per unit contact area, so it has less wear and stronger bearing capacity. The four groups of paired guide assemblies are tilted and arranged in a diamond shape at the four corners of the upper mold and the lower mold, which can be limited inside and outside and in multiple directions, thereby improving the guiding accuracy and having the advantages of long service life and stable operation.

[0014] Embodiments of the present utility model: Figures 1 to 3 As shown, an oblique insertion guide assembly for a mold includes four groups of paired guide assemblies arranged on an upper mold 1 and a lower mold 2, the guide assembly includes a convex part 3 fixed on the upper mold 1 and a concave part 4 fixed on the lower mold 2, the convex part 3 has a vertical contact outer wall 5, the concave part 4 has a groove 6, the groove 6 has a matching vertical contact inner wall 12, the convex part 3 enters the groove 6, the contact outer wall 5 of the convex part 3 and the contact inner wall 12 in the groove 6 are in close contact and sliding cooperation, so as to achieve the limitation of both sides of the convex part 3, and through the surface contact sliding cooperation, it has the characteristics of high rigidity and small load per unit contact area, so it has small wear and stronger bearing capacity, the four groups of guide assemblies are inclinedly arranged and distributed in a diamond shape at the four corners of the upper mold 1 and the lower mold 2, and are limited inside and outside and in multiple directions, which improves the guiding accuracy and has the advantages of long service life and stable operation.

[0015] As a preferred embodiment, the top of the protruding member 3 and the opening edge of the groove 6 of the concave member 4 are transitioned into rounded corners 7 to facilitate smooth introduction of the protruding member 3 into the groove 6 .

[0016] As a preferred embodiment, it includes a refueling device, which includes an oil supply pipeline 8. An oil storage tank 9 is provided on the contact outer wall 5 of the protrusion 3. The protrusion 3 has an oil supply channel connected to the oil storage tank 9. The oil supply pipeline 8 is installed on the protrusion 3 and communicates with the oil supply channel in the protrusion 3. In order to reduce the wear of the protrusion 3 and the concave part 4 during use, lubricating oil is regularly added to the oil supply channel of the protrusion 3 through the oil supply pipeline. The lubricating oil flows into the oil storage tank 9 on the contact outer wall 5 and penetrates into the contact surface of the protrusion 3 and the concave part 4, thereby reducing wear and making the fit smoother.

[0017] As a preferred embodiment, the protrusion 3 has a base portion 10, and the groove 6 is located above the base portion 10. The groove 6 has two sides of the protrusions 3 that cooperate with it, and the other two sides are open. An oil guide groove 11 is provided on the base portion 10, and the oil guide groove 11 is located on the corresponding open side of the groove 6. The oil guide groove 11 is inclined to facilitate the discharge of the lubricating oil overflowing from the groove 6 from the oil guide groove 11, thereby facilitating the renewal of the lubricating oil and preventing the lubricating oil from polluting the working environment.
