Description

Technical Field

[0001] The utility model relates to the technical field of monitoring cameras, in particular to a front shell mould of a monitoring camera which is easy to demould. Background Art

[0002] Surveillance cameras, also known as CCTV cameras, are devices designed to capture and transmit video images. They are widely used in security monitoring, traffic monitoring, industrial monitoring and other fields. Surveillance cameras capture images through their built-in optical systems (including lenses and apertures). The lens is responsible for focusing light to form a clear image, while the aperture controls the amount of light entering the lens to ensure image quality.

[0003] During the demoulding process of the plastic mold, the plastic is melted in the molding groove after heat treatment. After cooling, the plastic hardens in the mold groove, but the molded mold is not easy to remove from the mold groove.

[0004] A Chinese patent with publication number CN218535369U has been proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a quick demolding mold, comprising a base, a lower template, an upper template and a film pressing plate, the top outer wall of the base is provided with mold grooves distributed at equal distances, the inner wall of the mold groove is fixedly provided with a limit plate, the inner wall of the mold groove is slidably connected to a mold bottom panel, the mold bottom panel is located on the top of the limit plate, the side wall of the lower template is provided with slots distributed at equal distances and running through the mold groove, the inner wall of the slot is plugged with a telescopic rod, and the outer wall of the telescopic rod is movably connected to support rods distributed at equal distances. The utility model contracts the output shaft of the hydraulic push rod motor, the hydraulic push rod motor drives the connecting rod to move, the connecting rod drives the telescopic rod to move, the telescopic rod pulls the support rod, the support rod pushes the bottom panel of the mold upward, so that the bottom panel of the mold moves upward on the inner wall of the mold groove, and the mold formed in the mold groove is ejected to facilitate rapid demolding and collection of the mold. However, because the prior art demolds the finished product by mechanical means, and the wall thickness of the finished product of the front shell of the monitoring camera is relatively thin, if the ejection force is too large, it is easy to cause the finished product of the front shell of the monitoring camera to be deformed or broken, and it is easy to cause damage to the finished product of the front shell of the monitoring camera, which has certain limitations. Utility Model Content

[0005] The utility model aims to provide a surveillance camera front shell mold which is easy to demould, so as to solve the problems raised in the above background technology.

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

[0007] A surveillance camera front shell mold that is easy to demold, includes a lower mold and an upper mold, and the upper mold is arranged on the top of the lower mold; a bottom plate is fixedly installed at the bottom of the lower mold, and one end of the bottom plate is fixedly connected to a controller, and a plurality of hydraulic cylinders are arranged on both sides of the interior of the lower mold, and the output shaft of each hydraulic cylinder is fixedly connected to the surface of the bottom of the upper mold, and an air guide box is fixedly installed inside the bottom plate, and through holes are provided on both sides of the air guide box, and a second partition is fixedly installed inside the air guide box, and the interior of the air guide box on one side of the second partition is fixedly connected to the first partition, and the interiors of the first partition and the second partition are provided with through grooves, and piston plates are slidably arranged on the inner sides of the first partition and the second partition, and an electric push rod is fixedly installed inside the bottom plate on the top of the air guide box, and the output shaft of the electric push rod extends to the interior of the air guide box and is connected to the top of the piston plate. The surface is fixedly connected, and a slide plate is connected to one side of the first partition through a first spring, and the surface of one side of the slide plate fits with the inner wall of the air guide box, and the slide plate just covers the through hole opened on one side of the air guide box, and the inner wall spring of the air guide box on the other side of the second partition is connected to a movable plate by a second spring, and the surface of one side of the movable plate fits with the surface of the other side of the second partition, and the movable plate just covers the through groove opened inside the second partition, and the other side of the air guide box is fixedly connected to the surface of the bottom of the lower mold through a guide pipe, and a flow hole is opened on the inner wall of the lower mold, and a baffle rod is slidably installed inside the lower mold on the other side of the flow hole, and an electric push rod is fixedly installed on the bottom of the baffle rod, and the baffle rod just blocks the surface on the other side of the flow hole, and a filter component for filtering the gas entering the air guide box is provided on one side of the air guide box.

[0008] By installing the blocking rod, the opening and the flow hole on the surface of the lower mold can be sealed and blocked to avoid affecting the molding of the front shell product of the surveillance camera. After the front shell product of the surveillance camera is formed, the blocking rod can be driven to move downward automatically by installing the electric push rod, so that the opening of the flow hole can be exposed, so that the gas can be continuously infused between the front shell molded product of the surveillance camera and the lower mold in the future. By installing the electric push rod, the piston plate can be driven to move upward, and at the same time, an adsorption force can be formed on the slide plate and the movable plate, so that the slide plate is separated from the inner wall of the air guide box, so that external gas can be drawn into the interior of the air guide box. Then, by installing the electric push rod, the piston plate can be driven to move downward, and at the same time, a thrust can be formed on the slide plate and the movable plate, so that the slide plate fits with the inner wall of the air guide box again, and the movable plate is separated from the second partition plate, so that the gas can be guided to the space between the front shell molded product of the surveillance camera and the lower mold through the guide pipe, and the gas gradually penetrates into the tiny gap between the front shell molded product of the surveillance camera and the lower mold, so that the front shell molded product of the surveillance camera is gradually separated from the lower mold, and the demolding work is realized.

[0010] The above-mentioned technical scheme is adopted. In this scheme, by installing a filter plate, the gas entering the interior of the air guide box can be filtered to prevent impurities from following the gas into the interior of the air guide box, and then entering between the monitoring camera front shell molded product and the lower mold, causing scratches and damage to the surfaces of the lower mold and the monitoring camera front shell molded product, thereby improving the safety performance of the device. By installing a pull block, the contact area between the operator's hand and the connecting plate can be expanded, so that the operator can pull the filter plate upwards to clean or replace the filter plate.

[0011] A further improvement of the technical solution of the utility model is that: limit plates are fixedly installed on the top of the fixing frames on both sides of the connecting plate, and a rubber strip is attached to the inner surface of each limit plate, and the bottom of each rubber strip fits the surface of the top of the connecting plate.

[0012] The above technical solution is adopted. In this solution, by installing a limit plate and a rubber strip, the position of the connecting plate on the top of the fixed frame can be limited to a certain extent, thereby improving the stability of the filter plate being connected to the inside of the fixed frame, and the rubber strip can be deformed under a certain pressure. The operator pulls the pull block with a certain pulling force to deform the rubber strip, thereby separating the connecting plate from the rubber strip.

[0013] A further improvement of the technical solution of the utility model is that a sealing frame is attached to the outer surface of the piston plate, and the outer surface of the sealing frame is tightly fitted with the inner surfaces of the first partition plate and the second partition plate and the inner wall of the air guide box respectively.

[0014] By adopting the above technical solution, in this solution, the sealing effect between the piston plate and the first partition plate, the second partition plate and the contact surface of the air guide box can be increased by installing a sealing frame, thereby increasing the thrust and suction force of the electric push rod driving the piston plate to slide up and down, thereby improving the effect of guiding gas.

[0015] A further improvement of the technical solution of the utility model is that: sliding blocks are fixedly installed at both ends of the slide plate, sliding grooves are opened at both ends inside the air guide box, and each sliding block is slidably connected to the inside of each sliding groove.

[0016] The above technical solution is adopted, in which the sliding trajectory of the slide plate can be guided and limited by setting a slider and a slide groove, ensuring that the slide plate can cover the through hole inside the air guide box.

[0017] A further improvement of the technical solution of the utility model is that movable blocks are fixedly installed at both ends of the movable plate, movable grooves are opened at both ends inside the air guide box, and each movable block is slidably connected to the inside of each movable groove.

[0018] The above technical solution is adopted. In this solution, the sliding track of the movable plate can be guided and limited by providing the movable block and the movable groove, so as to ensure that the movable plate can cover the through groove provided on the surface of the second partition plate.

[0019] A further improvement of the technical solution of the utility model is that a limiting block is fixedly installed on the other side of the stop rod, a limiting groove is provided inside the lower mold, and the limiting block is slidably connected to the inside of the limiting groove.

[0020] The above technical solution is adopted. In this solution, the sliding trajectory of the baffle rod can be guided and limited by setting a limit block and a limit groove, ensuring that the electric push rod can just expose the other side of the flow hole in the process of driving the baffle rod to move downward, so as to facilitate the subsequent gas circulation.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a surveillance camera front shell mold which is easy to demold. After the electric push rod drives the blocking rod to separate from the flow hole, an air guide box and its internal structure are set, wherein the electric push rod is used to drive the piston plate to move upward and downward, so that external gas can be sucked into the interior of the air guide box, and the gas is guided to between the surveillance camera front shell molded product and the lower mold through the guide tube and the flow hole, and the above-mentioned action is repeated many times, so that the gas can gradually penetrate into the tiny gap between the surveillance camera front shell molded product and the lower mold, thereby gradually separating the surveillance camera front shell molded product from the lower mold, so as to facilitate the demolding of the surveillance camera front shell molded product. The overall demolding process is not easy to damage the surveillance camera front shell molded product and the lower mold, and has a protective effect on the surveillance camera front shell molded product and the lower mold.

[0023] 2. The utility model provides a surveillance camera front shell mold that is easy to demold. Through the mutual cooperation between the filtering components, the filter plate can prevent impurities from following the gas into the interior of the air guide box, thereby preventing impurities from entering between the surveillance camera front shell molded product and the lower mold and causing scratches and damage to the surface of the lower mold and the surveillance camera front shell molded product, thereby improving the safety performance of the device.

[0024] 3. The utility model provides a surveillance camera front shell mold that is easy to demold. By installing a sealing frame, the sealing effect of the piston plate and the contact surface between the first partition plate, the second partition plate and the air guide box can be increased, thereby increasing the thrust and suction generated by the piston plate during the up and down sliding process, thereby improving the effect of subsequent gas guidance, and further facilitating the demolding operation of the surveillance camera front shell molded product.
