Description

Technical Field

[0001] The utility model relates to the technical field of injection molding devices, and particularly relates to an injection mold for plastic part processing. Background Technique

[0002] Plastic parts, namely plastic components, are various parts made of plastic through different molding processes. An injection mold is an important tool for producing plastic products. It injects molten plastic materials into the mold and forms the required shape of the product after cooling.

[0003] After the plastic part is injection molded by the injection mold, the temperature of the plastic part inside the injection mold is relatively high. If the plastic part is taken out when the temperature is high, the molding effect of the plastic part is poor, and it is necessary to manually monitor the temperature of the injection mold and the plastic part inside. The injection mold can be opened only when the temperature of the plastic part decreases, and the required labor cost is relatively high. Therefore, an injection mold for plastic part processing is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an injection mold for plastic part processing to solve the problems raised in the above background technique: after the plastic part is injection molded by the injection mold, the temperature of the plastic part inside the injection mold is relatively high. If the plastic part is taken out when the temperature is high, the molding effect of the plastic part is poor, and it is necessary to manually monitor the temperature of the injection mold and the plastic part inside. The injection mold can be opened only when the temperature of the plastic part decreases, and the required labor cost is relatively high.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an injection mold for plastic part processing, including a lower template, a lower mold cavity is arranged at the center of the lower template, a lifting component is arranged on the upper surface of the lower template close to the lower mold cavity, an upper mold sleeve is fixedly connected to the upper surface of the lifting component, a temperature sensor is installed at the center of the upper surface of the upper mold sleeve, and the detection end of the temperature sensor extends into the upper mold sleeve. A warning component is fixedly connected to one side of the lower template, a proximity block is fixedly connected to the upper mold sleeve close to the warning component, the proximity block is directly opposite to the warning component, and an injection through hole is arranged on the side of the upper mold sleeve away from the warning component. The purpose of such a setting is: molten plastic can be injected between the lower template and the upper mold sleeve through the provided injection through hole, and it is molded under the extrusion of the mold cavity and the injected molten plastic between the lower template and the upper mold sleeve. After the molten plastic injection is completed, wait for the plastic part to cool and form.

[0006] Preferably, the lifting component includes two electric telescopic rods, and the two electric telescopic rods are installed on the lower template.

[0007] Preferably, the telescopic ends of the two electric telescopic rods are fixedly connected with a lifting connecting plate.

[0008] Preferably, one end of each of the two lifting connecting plates is fixedly connected to the upper die sleeve.

[0009] Preferably, the warning assembly includes a connecting vertical plate, and a proximity switch is fixedly installed at the top of the inner wall of the connecting vertical plate.

[0010] Preferably, the detection end of the proximity switch is directly opposite to the position of the proximity block, and a warning lamp is fixedly installed on the upper surface of the connecting vertical plate. The purpose of this setting is as follows: after the temperature of the plastic part drops to a suitable temperature, when the temperature sensor detects that the temperature of the plastic part has dropped, the electric telescopic rod pushes the lifting connecting plate to move upward. At this time, the upper die sleeve moves upward accordingly, and the proximity block approaches the proximity switch. When the proximity block approaches the proximity switch, the proximity switch controls the electric telescopic rod to stop. At this time, the lower template is separated from the upper die sleeve, and the proximity switch turns on the warning lamp to warn the operator to take out the plastic part, thereby completing the automatic monitoring of the temperature between the lower template and the upper die sleeve, eliminating the need for manual monitoring and saving manpower.

[0011] The technical effects and advantages of the present utility model:

[0012] (1) After the temperature of the plastic part in this device drops to a suitable temperature, when the temperature sensor detects that the temperature of the plastic part has dropped, the electric telescopic rod pushes the lifting connecting plate to move upward. At this time, the upper die sleeve moves upward accordingly, and the proximity block approaches the proximity switch. When the proximity block approaches the proximity switch, the proximity switch controls the electric telescopic rod to stop. At this time, the lower template is separated from the upper die sleeve, and the proximity switch turns on the warning lamp to warn the operator to take out the plastic part, thereby completing the automatic monitoring of the temperature between the lower template and the upper die sleeve, eliminating the need for manual monitoring and saving manpower. This solves the problem that after the plastic part is injection-molded through an injection mold, the temperature of the plastic part inside the injection mold is relatively high. If the plastic part is taken out when the temperature is high, the forming effect of the plastic part is poor, and it is necessary to manually monitor the temperature of the injection mold and the plastic part inside it. The injection mold can only be opened when the temperature of the plastic part drops, resulting in a relatively high labor cost.

[0013] (2) This device can inject molten plastic between the lower template and the upper die sleeve through the provided injection through-hole, and it is formed under the extrusion of the mold cavity between the lower template and the upper die sleeve and the injected molten plastic. After the molten plastic injection is completed, wait for the plastic part to cool and form. Description of the Drawings

The detection end of the temperature sensor 5 extends into the interior of the upper die sleeve 2. A warning component 4 is fixedly connected to one side of the lower template 1. A proximity block 6 is fixedly connected to the upper die sleeve 2 near the warning component 4. The proximity block 6 is directly opposite to the warning component 4 in position.

A proximity switch 402 is fixedly installed at the top of the inner wall of the connecting vertical plate 401. The detection end of the proximity switch 402 is directly opposite to the proximity block 6 in position. A warning light bulb 403 is fixedly installed on the upper surface of the connecting vertical plate 401.

[0021] Working principle of the utility model: The molten plastic can be injected between the lower template 1 and the upper die sleeve 2 through the injection through hole 7 provided. It is formed under the extrusion of the die groove between the lower template 1 and the upper die sleeve 2 and the injected molten plastic. After the molten plastic injection is completed, wait for the plastic part to cool and form. After the temperature of the plastic part drops to a suitable temperature, the temperature sensor 5 can detect that the temperature of the plastic part has dropped, and the electric telescopic rod 301 pushes the lifting connecting plate 302 to move upward. At this time, the upper die sleeve 2 moves upward accordingly, and the proximity block 6 approaches the proximity switch 402. When the proximity block 6 approaches the proximity switch 402, the proximity switch 402 controls the electric telescopic rod 301 to stop. At this time, the lower template 1 is separated from the upper die sleeve 2, and the proximity switch 402 turns on the warning light bulb 403 to warn the operator to take out the plastic part.
