Description

Technical Field

[0001] This utility model belongs to the technical field of flat vulcanizing machines, and specifically relates to a discharge device for a flat vulcanizing machine. Background Technology

[0002] Flat vulcanizing machines are a type of molding machine suitable for the rubber and plastics industries. When using a flat vulcanizing machine, the plastic or rubber raw material is placed on the lower mold plate. The upper mold plate is fixedly connected to the upper heating plate, and the lower mold plate is fixedly connected to the lower heating plate. The upper and lower mold plates are closed, and pressure is applied under the intelligent constant temperature of the heating plates to shape the raw material. After the upper and lower mold plates are opened, the material is removed manually.

[0003] Patent application number 202322686881.4 discloses a discharge device for a flat vulcanizing machine, including a working body. The working body includes a base, and a control box is fixedly connected to the surface of the base. A hydraulic cylinder is fixedly installed on the base, and a hydraulic column is provided inside the hydraulic cylinder. A heating plate is fixedly connected to the surface of the hydraulic column, and a lower template is fixedly connected to the surface of the heating plate. A working plate is fixedly connected to the surface of the hydraulic cylinder, and a support frame is fixedly connected to the working plate. An upper template is fixedly connected to the surface of the support frame, and a driving device is installed on the surface of the working plate. The driving device includes a fixing frame.

[0004] The above technical solution uses a cylinder to push the lower template to the surface of the conveyor belt. Since the lower template is in a high temperature state, it will cause damage to the surface of the conveyor belt. At the same time, the lower template needs to be manually demolded. Furthermore, after demolding, the conveyor belt cannot transport the lower template to the top of the heating plate, resulting in poor reset efficiency of the lower template after transportation. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a discharge device for a flat vulcanizing machine. This discharge device aims to solve the technical problems in the existing technology, such as the lower mold being damaged on the surface of the conveyor belt due to the high temperature, the need to manually demold the lower mold, and the inability of the conveyor belt to transport the lower mold to the top of the heating plate after demolding, resulting in poor reset efficiency of the lower mold after conveying.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a discharge device for a flat vulcanizing machine. The discharge device includes a base and a main body of the discharge device with a frame structure disposed above the base. Both ends of the main body of the discharge device are provided with sliding grooves, and a lower mold is slidably engaged on the main body of the discharge device. A demolding template is embedded and fixed in the bottom wall of the lower mold, and an upper mold is provided at the top of the lower mold. Both ends of the main body of the discharge device are embedded and fixed with a first electric push rod connected to the upper mold, and a drive mechanism connected to the lower mold is provided between the two sliding grooves.

[0009] When using this technical solution, grooves are provided at both ends of the main body of the discharge device. After the motor starts, it drives two lead screws to rotate synchronously in the forward direction through a synchronous pulley and a synchronous belt. During the rotation, the lower mold and the upper mold are moved out of the base. After they are moved out, the two first electric push rods are activated to move synchronously. The top of the first electric push rod is attracted and fixed to the magnet block, and pushes the upper mold to move upward to separate it from the lower mold. At the same time, the push block at the top of the second electric push rod extends into the through hole and pushes the demolding plate upward, thereby separating the plate from the lower mold, which facilitates the separation of the upper mold and the lower mold. This device improves the ease of demolding flat plates. The first electric push rod moves the upper mold downwards, and the positioning rod at the top of the lower mold fits into the positioning hole and is in contact with the upper mold. The second electric push rod moves the push block out of the through hole. After the upper mold is installed, the electric push rod is activated to drive the two lead screws to rotate synchronously, so that the upper and lower molds move to the top of the base in the main body of the discharge device. The hydraulic equipment drives the lifting plate to move downwards, so that the two electric heating plates fit into the upper and lower molds respectively, which facilitates repeated movement of the molds and improves the reset efficiency after mold conveying.

[0010] Preferably, a hydraulic device is fixedly installed at the top of the base, and a lifting plate is provided between the base and the hydraulic device. The top of the lifting plate is connected to the hydraulic device, and a heating plate is embedded in the side of the lifting plate facing the base.

[0011] Furthermore, the driving mechanism includes a lead screw that is rotatably inserted into the slide groove and a motor fixed to the side wall of the main body of the discharge device. The motor shaft is fixedly connected to the lead screw, and both ends of the lower mold are embedded in the slide groove and threadedly connected to the lead screw.

[0012] Furthermore, a synchronous pulley is fixedly sleeved at one end of the lead screw that passes through the main body of the discharge device, and a synchronous belt is meshed between the two synchronous pulleys.

[0013] Furthermore, a support base is fixedly installed at the bottom of the main body of the discharge device, and a second electric push rod is embedded in the top of the support base.

[0014] Furthermore, the bottom end of the lower mold is provided with a through hole that communicates with the ejector plate, and the top end of the second electric push rod is fixed with a push block inserted into the through hole.

[0015] Furthermore, both ends of the upper mold are embedded with magnet plates that are attracted and fixed to the first electric push rod, and the bottom end of the upper mold has multiple positioning holes in a rectangular array, and the top end of the upper mold is fixed with a positioning rod that fits into the positioning hole.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model features sliding grooves at both ends of the main body of the discharge device. After the motor starts, it drives two lead screws to rotate synchronously in the forward direction via a synchronous pulley and synchronous belt. During the rotation, the lower mold and the upper mold are moved out of the base. After they are moved out, the two first electric push rods are activated to move synchronously. The top of the first electric push rod is attracted and fixed to the magnet block, and pushes the upper mold to move upward to separate it from the lower mold. At the same time, the push block at the top of the second electric push rod extends into the through hole and pushes the demolding plate upward, thereby separating the plate from the lower mold. This facilitates the separation of the upper mold and the lower mold and improves the convenience of demolding the plate.

[0019] The first electric push rod drives the upper mold to move downwards, and the positioning rod at the top of the lower mold fits into the positioning hole and is in contact with the upper mold. The second electric push rod drives the push block to move out of the through hole, and after the upper mold is installed, the electric push rod is started to drive the two lead screws to rotate synchronously, so that the upper mold and the lower mold move to the top of the base in the main body of the discharge device. The hydraulic equipment drives the lifting plate to move downwards, so that the two electric heating plates fit into the upper mold and the lower mold respectively, which facilitates the repeated movement of the mold and improves the reset efficiency of the mold after delivery.

A second electric push rod 15 is embedded and fixed at the top end of the support base 14. After the motor starts, it drives the two lead screws 11 to rotate synchronously in the forward direction through the synchronous pulley 18 and the synchronous belt 19. During the rotation, the lower mold 10 and the upper mold 6 are moved out of the base 1. After they are moved out, the two first electric push rods 9 are activated to move synchronously.
