Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically an auxiliary clamping mechanism for plastic molds. Background Technology

[0002] Plastic molds are used to mold softened plastic products after cooling, ultimately producing plastic products of a specified style. During the production of plastic products, clamps are usually used to hold and fix the upper and lower molds to prevent the plastic molds from shifting position during injection molding.

[0003] A search of Chinese patent CN221161291U reveals an auxiliary clamping mechanism for plastic molds. By rotating a knob, a drive wheel rotates, which in turn drives a driven wheel via a transmission belt. This drives two threaded rods to rotate simultaneously, which in turn drive a pressure plate to clamp and fix the mold. Several anti-slip blocks at the bottom of the pressure plate increase friction between the pressure plate and the mold, thereby increasing the stability of the fixed mold. Compared to existing technologies, this mechanism provides a quick clamping and fixing effect for the mold.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The upper mold is not convenient to adapt to molds of different sizes. After clamping, the lifting and lowering are directly controlled to combine with the lower mold to make plastic products. The upper mold and the lower mold are not easy to align, which affects the quality of the plastic products. Moreover, the structure is complex and not easy to maintain, which reduces the efficiency of the auxiliary clamping mechanism for plastic molds. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary clamping mechanism for plastic molds to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is: an auxiliary clamping mechanism for plastic molds, including a base plate, a support seat fixedly connected to the top outer wall of the base plate, a bracket fixedly connected to the top outer wall of the base plate, and further comprising; A clamping mechanism, wherein the clamping mechanism is disposed inside the bracket; The clamping mechanism includes a motor mounted on one outer wall of the top of the bracket. One end of the motor's output shaft is connected to a double-acting lead screw via a coupling. The outer walls of both sides of the double-acting lead screw are connected to sliding frames via threads. One outer wall of the sliding frame is provided with a slide rail. A clamping plate is slidably connected to the inner wall of the slide rail. An electric push rod is mounted on the outer wall of the top of the bracket. One end of the piston rod of the electric push rod is fixedly connected to a telescopic plate. Both ends of the piston rod of the telescopic plate are fixedly connected to the outer wall of the clamping plate. A through hole is opened on the outer wall of the bottom end of the clamping plate. Clamping grooves are opened on the outer walls of both sides of the clamping plate. Anti-slip pads are adhered to the inner walls of the clamping grooves.

[0007] Preferably, the bracket is U-shaped, the sliding frame is slidably connected to the inner wall of the bracket, and the two outer walls of the top of the sliding frame are fixedly connected with reinforcing blocks.

[0008] Preferably, limit rods are fixedly connected to the outer walls on both sides of the top of the telescopic plate, and limit holes are opened on the outer walls on both sides of the top of the bracket, with the limit rods slidably connected to the inner walls of the limit holes.

[0009] Preferably, the through hole is adapted to the size of the bidirectional lead screw, the top outer wall of the support base is provided with a lower mold, and the top outer wall of the lower mold is provided with an upper mold.

[0010] Preferably, the upper mold is adapted to the size of the clamping plate, and the upper mold is adapted to the position of the lower mold and the bidirectional lead screw.

[0011] This utility model provides an improved auxiliary clamping mechanism for plastic molds, which has the following improvements and advantages compared with the prior art: Firstly, this utility model is equipped with a base plate, support seat, bracket, bidirectional lead screw, clamping plate, and sliding frame. The motor drives the bidirectional lead screw to rotate, thereby causing the two sliding frames to move and move closer together. This causes the two clamping plates to clamp and fix the upper mold, aligning the upper mold with the lower mold. The electric push rod is activated to control the telescopic plate to descend, thereby causing the two clamping plates to move the upper mold down. The clamping plates slide on the sliding frame, and the upper and lower molds work together to produce plastic products. The position of the clamping plates can be adjusted according to the size of the upper mold. After adjustment, the lifting and lowering can be directly controlled by the electric push rod. This solves the problems of small adaptability range, difficulty in aligning the upper and lower molds after clamping and directly controlling the lifting and lowering to combine with the lower mold to produce plastic products, which affects the quality of plastic products. Moreover, the structure is simple and easy to maintain, improving the efficiency of the auxiliary clamping mechanism for plastic molds. Secondly, this utility model improves the practicality of the auxiliary clamping mechanism for plastic molds by setting a limiting rod and an anti-slip pad. The limiting rod slides on the bracket when the telescopic plate is raised and lowered, which limits the structure and improves the stability of the structure. The anti-slip pad at the clamping plate position increases the friction and prevents it from falling off. Attached Figure Description
