Description

TECHNICAL FIELD

[0001] The utility model relates to a mould frame, in particular to a lateral positioning mould frame. BACKGROUND

[0002] Mould is important process equipment in industrial production, and mould can be roughly divided into two parts, mould core and mould frame, and a part of working parts in the mould is directly contacted with mould finished products, such as male die of hardware mould, female die is directly contacted with the metal plate to be processed, and mould core and mould cavity of plastic mould are directly contacted with plastic finished products, and these working parts are called "mould core".

[0003] In the process of stamping processing, the position between the product and the mould needs to be positioned, so that the product can be accurately stamped into shape. For products of non-full-automatic stamping processing technology, the placing operation of the product to be processed on the mould is mostly manual, and in order to facilitate the product to be placed into the mould, the existing mould is usually provided with an open structure. The mould with the open structure needs to be fixed with a lateral positioning structure to ensure the yield rate of product processing. The existing lateral positioning structure is divided into fixed and movable parts, and the operation of the movable part is mostly manual holding of the supporting rod abutting against the movable part to make it in the positioning state. The positioning force of the abutting operation is unstable, and the operation of switching the movable part to the non-positioning state also needs to be manually operated, which has certain safety hazards. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a lateral positioning mould frame, which is more convenient to operate, provides more stable positioning force and avoids the existing safety hazards.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a lateral positioning mould frame, comprising a mould base, a lower mould fixing assembly arranged on the mould base and a stamping processing area formed in the lower mould fixing assembly and used for placing a product to be processed, fixed side positioning blocks and movable side positioning blocks are arranged on both sides of the stamping processing area, the movable side positioning blocks are reciprocally slidably arranged on the lower mould fixing assembly in the direction from the stamping processing area to the fixed side positioning blocks, a control handle is arranged on the outer side of the lower mould fixing assembly, and a linkage assembly is arranged between the control handle and the movable side positioning blocks to switch the movable side positioning blocks between the positioning position and the non-positioning position.

[0006] By adopting the technical scheme, the product to be processed is placed in the stamping processing area, the control handle drives the movable side positioning block to move towards the stamping processing area through the linkage assembly and switches between the positioning position and the non-positioning position, so as to realize the positioning function of the product in the stamping processing area together with the fixed side positioning block. The above structure makes the lateral positioning operation more convenient, so as to provide more stable positioning force; and the position of the hand control is far away from the stamping processing area, so as to avoid the safety hazard.

[0007] Further, the linkage assembly comprises a cam rotationally arranged and abutting the movable side positioning block in the periphery, and a tension spring connecting the cam and the movable side positioning block, the tension spring drives the movable side positioning block to always abut the periphery of the cam.

[0008] By adopting the technical scheme, the tension spring drives the movable side positioning block to always abut the periphery of the cam, so as to realize the reciprocating movement of the movable side positioning block towards the stamping processing area driven by the rotation of the cam.

[0009] Further, the cam is rotationally arranged on the die holder through a main shaft, the main shaft is provided with a connecting screw, and the movable side positioning block is provided with a positioning screw, and the tension spring is connected to the connecting screw and the positioning screw.

[0010] By adopting the technical scheme, the connection of the tension spring is realized through the above structure, so that the structure is more compact.

[0011] Further, the lower die fixing assembly is provided with a first positioning groove matched with the positioning screw for positioning the movable side positioning block at the positioning position, so as to limit the movable side positioning block moving towards the stamping processing area.

[0012] By adopting the technical scheme, the positioning screw moves with the movable side positioning block, and when the positioning screw abuts the first positioning groove, the movable side positioning block is just positioned at the positioning position, so as to improve the control precision and ensure the processing quality.

[0013] Further, the positioning assembly has a positioning state and a non-positioning state, the positioning assembly positions the movable side positioning block at the non-positioning position, and the movable side positioning block can drive the positioning assembly to switch between the positioning state and the non-positioning state.

[0014] By adopting the technical scheme, the positioning assembly positions the movable side positioning block at the non-positioning position, so as to avoid the accidental movement of the movable side positioning block caused by accidental triggering and improve the safety in use.

[0015] Further, the positioning assembly comprises a positioning column slidingly arranged on the lower mold fixed assembly and reciprocally moving towards the movable side positioning block, a driving spring driving the positioning column to abut against the movable side positioning block, and a second positioning groove formed on the movable side positioning block and embedded with the positioning column.

[0016] By adopting the above technical scheme, the positioning column is embedded in the second positioning groove to position the movable side positioning block in the non-positioning position, when the positioning assembly is switched from the positioning state to the non-positioning state, the separation of the positioning column and the second positioning groove can be realized by exerting a larger force on the control handle, which avoids the mis-triggering and does not affect the convenience of control.

[0017] Further, one side of the movable side positioning block towards the stamping processing area is formed with a V-shaped positioning notch.

[0018] By adopting the above technical scheme, the products of different sizes to be processed can be adapted.

[0019] Further, the lower mold fixed assembly comprises a base plate, a lower mold block mounted on the base plate, and a cover plate arranged above the base plate, and the fixed side positioning block is located between the base plate and the cover plate and on one side of the lower mold block.

[0020] By adopting the above technical scheme, the stamping processing is formed, and the fixed side positioning block is conveniently fixed.

[0021] In summary, the lateral positioning operation of the utility model is more convenient, which provides more stable positioning force and avoids the existing safety hazards. BRIEF DESCRIPTION OF DRAWINGS
