Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a mold processing positioning device. Background Technology

[0002] Mold machining and positioning is crucial in the mold manufacturing process for fixing the mold and ensuring machining accuracy. It enables the mold to be quickly installed and aligned on the machining table, thereby improving machining efficiency and the yield of finished products.

[0003] Chinese Patent No. CN 220972307 U discloses a mold processing positioning device, including a processing table, a positioning seat, and a fixing mechanism. The processing table has several positioning holes, and the positioning seat has a lifting plate and a positioning cylinder inside. The position of the positioning seat is adjusted by controlling the lifting and lowering of the positioning cylinder through a handle and a pull rope. This device simplifies the movement operation of the positioning seat.

[0004] The above-mentioned devices have significant drawbacks in practical applications: the positioning holes and positioning seats of the processing table lack protective design, allowing contaminants such as metal shavings and coolant generated during processing to easily penetrate the positioning holes and the interior of the mechanism. This can lead to jamming of the positioning cylinder, failure of spring elasticity, or wear of the pull rope, severely affecting positioning accuracy and equipment lifespan. Furthermore, the accumulation of contaminants increases the frequency of cleaning and maintenance, further driving up production costs.

[0005] Therefore, there is an urgent need for a mold processing positioning device with efficient protection functions to solve the problems of decreased accuracy and high maintenance costs caused by contaminant intrusion. Utility Model Content

[0006] The purpose of this invention is to provide a mold processing positioning device. This device, through multi-layer protection and self-cleaning design, effectively solves the problems of decreased positioning accuracy and high maintenance costs caused by contaminant intrusion.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mold processing positioning device, including a processing table, a positioning seat and a fixing mechanism, wherein a positioning guide column is fixed on the positioning seat, and a plurality of positioning circular holes are opened at the top of the processing table, and a lifting plate and a positioning column are provided inside the positioning seat, and a dustproof cover plate that can be opened and closed is provided at the top of each positioning circular hole, the dustproof cover plate being connected to the processing table by a hinge, and the dustproof cover plate completely covering the opening of the positioning circular hole when closed.

[0008] By adopting the above technical solution, the dust cover effectively prevents contaminants such as metal shavings and coolant from entering the positioning hole. The openable design of the dust cover allows for quick opening or closing when needed without affecting the normal operation of the equipment. The dust cover is connected to the processing table via a hinge, ensuring that the dust cover remains stable in the closed state and preventing accidental opening due to vibration or external force, thereby ensuring the protective effect of the positioning hole.

[0009] The dust cover is further configured such that a locking pin is provided at the hinge of the dust cover to secure the dust cover in place, and the locking pin passes through the corresponding hole in the dust cover and the processing table.

[0010] By adopting the above technical solution, the dust cover is connected to the processing table via a hinge and is fixed by a locking pin in the closed state to ensure the stability of the cover. The dust cover can reliably cover the positioning hole and prevent pollutants from entering.

[0011] The further configuration is as follows: the upper surface of the processing table is provided with insertion slots around the perimeter, and anti-chip baffles are vertically inserted into the insertion slots.

[0012] By adopting the above technical solution, the chip baffle is inserted into the slot, which facilitates installation and disassembly; the chip baffle can effectively block metal chips, while also facilitating cleaning and maintenance.

[0013] The positioning cylinder is further configured such that it has an annular sealing groove, and an elastic sealing ring is embedded in the sealing groove. When the positioning cylinder is inserted into the positioning hole, the sealing ring fits against the surface of the processing table to form a seal.

[0014] By adopting the above technical solution, the elastic sealing ring on the positioning cylinder fits into the surface of the positioning hole to form a seal, preventing coolant leakage.

[0015] The positioning seat is further configured such that a dust cover is provided on the outside of the positioning seat, the dust cover covers the positioning guide post, the fixing mechanism and the positioning seat, and the dust cover is slidably connected to the positioning seat through a slide rail.

[0016] By adopting the above technical solution, the dust cover can protect the guide column, fixing mechanism and positioning seat when the device is not in use, and can also prevent dust without hindering the maintenance and operation of the equipment. The dust cover is slidably connected to the positioning seat through a slide rail, which makes it easy to open and quickly disassemble when the device is in use.

[0017] The further configuration is as follows: the surface of the processing table is provided with a guide groove, the guide groove is radially distributed around the positioning circular hole, and the bottom of the guide groove extends obliquely out of the edge of the processing table.

[0018] By adopting the above technical solution, the guide channel guides the coolant to flow smoothly, and the guide channel design effectively prevents coolant accumulation and reduces the impact on the equipment.

[0019] A further configuration is provided: the positioning seat is equipped with a self-cleaning brush, and when the lifting plate moves up and down, the self-cleaning brush contacts the peripheral wall of the positioning cylinder and removes debris.

[0020] By adopting the above technical solution, the self-cleaning brush automatically removes debris from the positioning cylinder when the lifting plate moves, reducing maintenance workload. The self-cleaning function significantly reduces the maintenance frequency and cost of the equipment.

[0021] The chip-proof baffle is further configured such that a magnetic adsorption strip is provided on the inner side of the chip-proof baffle, and the magnetic adsorption strip is adsorbed and fixed to the metal part of the side wall of the processing table.

[0022] By adopting the above technical solution, the magnetic adsorption strip can adsorb metal debris, further reducing the accumulation of pollutants and keeping the equipment clean. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] refer to Figures 1 to 5A mold processing positioning device includes a processing table 1, a positioning seat 2, and a fixing mechanism 3 (the fixing mechanism 3 is a reference feature in the background art, and its specific structure will not be described in detail; the fixing mechanism 3 includes a spring and a lifting handle, etc.). The processing table 1 is a rectangular metal platform. A positioning guide post 21 is fixed on the positioning seat 2. Several positioning circular holes 11 are opened at the top of the processing table 1, and the positioning circular holes 11 are distributed in a rectangular array. A lifting plate 33 and a positioning column 34 are provided inside the positioning seat 2. Each positioning circular hole 11 is provided with an openable and closable circular dust cover 4 at its top. Each dust cover 4 is connected to the processing table 1 by a stainless steel hinge 41. The maximum size of the dust cover 4 is slightly larger than the opening of the positioning circular hole 11. When closed, the dust cover 4 completely covers the opening of the positioning circular hole 11. The hinge 41 is welded to the surface of the processing table 11.

[0031] The dust cover 4 has a locking pin 42 at the hinge 41 for fixing the dust cover 4 closed. The pin has a diameter of 1mm and the locking pin 42 passes through the corresponding hole between the dust cover 4 and the processing table 1 to achieve fixation.

[0032] Insertion slots 12 are provided around the edges of the processing table 1. A metal chip guard 5 is vertically inserted into the insertion slots 12. The chip guard 5 is 100mm high. A magnetic adsorption strip 52 is embedded on the inner side of the chip guard 5. The magnetic adsorption strip 52 is magnetically fixed to the side wall of the processing table 1.

[0033] The positioning seat 2 has a cuboid structure. Inside the positioning seat 2, there is a lifting plate 33. Four positioning cylinders 34 are vertically welded to the bottom of the lifting plate 33. The bottom end of the positioning cylinders 34 is machined with an annular sealing groove 6. The sealing groove 6 is fitted with an elastic sealing ring 61 made of silicone. When the positioning cylinders 34 are inserted into the positioning holes 11, the sealing rings 61 are deformed by pressure, and the sealing rings 61 and the positioning holes 11 form an annular sealing surface.

[0034] Radial guide grooves 8 are machined around the positioning holes 11 on the surface of the processing table 1. The guide grooves 8 are 3mm in diameter and connect to each positioning hole 11. The bottom of the guide grooves 8 extends to the edge of the table surface at a 5° angle. A U-shaped dust cover 7 is installed on the outside of the positioning seat 22 via an aluminum alloy slide rail 71. The dust cover 7 covers the positioning guide post 21 and the fixing mechanism 33. The slide rail 71 has a stroke of 200mm. When the device needs to be used, the slide rail 71 can be manually slid to expose the operating area.

[0035] A self-cleaning brush 9 is fixed to the bottom of the positioning base 2. The self-cleaning brush 9 is made of nylon and is arranged in a ring around the positioning cylinder 34. When the lifting plate 33 moves up and down, the self-cleaning brush 9 contacts the peripheral wall of the positioning cylinder 34 and scrapes off the attached debris.

[0036] Overall workflow: Hold the positioning seat 2 and pull the handle upwards. The lifting plate 33 will rise via the pull rope 35, the positioning cylinder 34 will retract, and the dust cover 4 will flip open via the hinge 41. Then, slide the positioning seat 2 along the surface of the processing table 1 to the target position, release the handle, and the spring will push the lifting plate 33 downwards. The positioning cylinder 34 will insert into the corresponding positioning hole 11, and the sealing ring 61 will fit and seal against the table surface. Then, close the dust cover 4 and insert the locking pin 42, install the chip baffle 5, and slide the dust cover 7 to cover the mechanism. During processing, debris will be discharged through the guide channel 8. When the lifting plate 33 moves, the self-cleaning brush 9 will remove the residue on the surface of the positioning cylinder 34. Remove the locking pin 42 and the chip baffle 5, slide the dust cover 7 to expose the mechanism, and then you can clean or replace the sealing ring 61.
