Description

Pneumatic demoulding mould of annular laser radar outer cover with top cover
Technical Field
The utility model relates to a production takes grinding apparatus technical field of the annular laser radar dustcoat of top cap, especially a take pneumatic drawing of patterns mould of the annular laser radar dustcoat of top cap.
Background
With the development of science and technology, the laser radar detection technology is gradually commercialized, and the fields which are most applied at present are industries such as unmanned driving, industrial distance measurement, warehouse logistics and the like. The laser radar dustcoat is the outside protective housing of whole laser radar subassembly, its key feature: 1) the design requirement is met, 2) the optical design requirement of the laser radar is met, 3) the infrared band light is highly transmitted through 4) and almost all plastic injection molding parts are obtained. The structural design of the annular laser radar outer cover with the top cover is widely applied to laser radars in various fields.
Due to the optical design requirement, the laser radar outer cover is generally designed into a ring shape, the demoulding inclination of the periphery is smaller, and the periphery is generally 1 degree or even smaller. The characteristic circumference of the annular laser radar outer cover structure is a closed ring, and the holding force on the movable mold core is very large according to the principle of expansion with heat and contraction with cold in the cooling stage after injection molding, and particularly the ejection and demolding are relatively difficult due to the demolding inclination of 1 degree or even smaller. The traditional ejector pin or ejector block ejection mechanism is applied to an annular laser radar outer cover, and the problems of unsmooth demolding and peeling damage caused by small demolding angle are aggravated due to slight imbalance of ejection. And because the annular laser radar outer cover has large holding force on the movable mold core, the ejector pin push block can generate certain depression or unevenness on the ejector plane after being ejected, and the appearance and the air tightness of the laser radar outer cover and the whole machine after assembly are directly influenced.
In order to solve the above problems, the present invention is proposed.
Disclosure of Invention
An object of the utility model is to provide a take pneumatic drawing of patterns mould of annular laser radar dustcoat of top cap, the gaseous ejecting scheme of application has avoided traditional thimble or ejector pad to sink in the ejecting thimble seal and the top of producing in laser radar dustcoat bottom, and the outward appearance and the bad problem of gas tightness that lead to.
The utility model discloses a following mode realizes, a take pneumatic drawing of patterns mould of annular laser radar dustcoat of top cap, its characterized in that: including cover half core and movable mould core, both closed formation one take the annular die cavity of top cap, are provided with one at the middle part of cover half core and run through the runner of cover half core, be provided with on the movable mould core one with high-pressure gas injection laser radar dustcoat with the gas passage of the centre of movable mould core, it is used for ejecting still to be provided with one on the movable mould core the T type ejector pin of laser radar dustcoat, the export of gas passage set up in the below of the T type head of T type ejector pin, the lower extreme of T type ejector pin is provided with an thimble board, the lower extreme of thimble board is provided with and is used for promoting the mould ejector pin of thimble board.
Further, the ejection distance range of the ejector rod is 1mm to 3 mm.
The beneficial effects of the utility model reside in that: the utility model utilizes the uniformity ejection of the gas pressure intensity to replace the ejection of a traditional thimble or a push block, avoids the problems of product falling damage and ejection deviation ejection irregularity caused by the imbalance of the traditional ejection, and avoids the influence of the step section difference generated by the ejection of the traditional thimble or the push block on the bottom end surface of the laser radar outer cover on the air tightness requirement of the product during the whole assembly; the utility model is simple in operation, be applicable to the stable production of moulding plastics in batches.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 to 4, in an embodiment of the present invention, a pneumatic demolding mold for a ring-shaped laser radar housing with a top cover comprises a fixed mold core 1 and a movable mold core 2, which are closed to form a ring-shaped mold cavity 3 with a top cover, a sprue 4 penetrating through the fixed die core 1 is arranged in the middle of the fixed die core 1, a gas channel 6 for injecting high-pressure gas into the middle of the laser radar outer cover 5 and the movable die core 2 is arranged on the movable die core 2, the movable mould core is also provided with a T-shaped ejector rod 7 for ejecting the laser radar outer cover 5, the outlet of the gas channel 6 is arranged below the T-shaped head of the T-shaped ejector rod 7, the lower end of the T-shaped ejector rod 7 is provided with an ejector plate 8 which is used for fixing the ejector rod, and is fixed on other structures of the die, and the lower end of the ejector plate is provided with a die ejector rod 9 for pushing the ejector plate.
The utility model discloses a theory of operation does: injecting glue into a die cavity from a pouring gate, opening the die after the glue is formed into a laser radar outer cover, opening the fixed die core and the movable die core along with the die, fixing the annular laser radar outer cover with a top cover on the movable die core, opening a gas channel switch on the die, introducing a gas channel into the inner side of the movable die core by high-pressure gas, providing ejection force through a die ejector rod to push the ejector plate, pushing the T-shaped ejector rod to eject upwards and slowly for a distance of 1mm to 3mm, filling the high-pressure gas to the middle of the annular laser radar outer cover with the top cover and the movable die core along a separated gap, pushing the annular laser radar outer cover with the top cover out by utilizing the uniformity of gas pressure along with the injection of the high-pressure gas, separating the annular laser radar outer cover from the movable die core, and completing the ejection and de-molding.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
