A device for assisting in cutting products using plastic molding molds

Abstract

The present invention provides a device for assisting the cutting of products with a plastic molding mold, and relates to the technical field of assisting the cutting of plastic molds, including a limit frame; a groove is provided in the middle position of the top of the limit frame, and the lower rear position of the inner portion of the limit frame groove is an inclined through groove, a lower mold is slidably connected in the groove of the limit frame, and the front-to-back length of the limit frame groove is twice the front-to-back length of the lower mold. In combination with the position of the saw blade of cutting saw A being flush with the height of the top of the lower mold and the position of the saw blade of cutting saw B being flush with the height of the top of the lower mold, when the two opposing blocks are approached, the saw blade of cutting saw A and the saw blade of cutting saw B are approached to cut and remove the burrs above the plastic product at the top of the lower mold. This solves the problem that when the plastic mold is demolding the plastic product, the plastic product is simply taken out, the steps are single, and the plastic product needs to be processed again for subsequent correction of the appearance corner position, which is time-consuming and labor-intensive, and cannot be completed in one step.

Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary cutting of plastic molds, and more specifically, particularly relates to a device for auxiliary cutting of plastic molding mold products. Background Art

[0002] A plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low-foaming molding. The coordinated changes of the mold convex, concave mold and auxiliary molding system can process a series of plastic parts of different shapes and sizes. It mainly includes a concave mold with a variable cavity composed of a concave mold combination base plate, a concave mold assembly and a concave mold combination pallet, and a convex mold with a variable core composed of a convex mold combination base plate, a convex mold assembly, a convex mold combination pallet, a cavity truncation assembly and a side-section combination plate. In order to improve the performance of plastics, various auxiliary materials such as fillers, plasticizers, lubricants, stabilizers, colorants, etc. must be added to the polymer to become a plastic with good performance. After the plastic mold performs the molding steps on the plastic product, the molding material needs to be cut to ensure the beauty and practicality of the product and avoid burrs on the product.

[0003] Similar to the current plastic molding molds, there are still the following deficiencies in the production and preparation process:

[0004] When a plastic product is demoulded from a plastic mold, the plastic product is simply taken out, which is a single step.

The opposing plate 204 is located directly above the bidirectional motor 201, and the middle position of the top of the opposing plate 204 is fixedly connected to the rear end position of the bottom of the positioning plate 205. The front end position of the bottom of the positioning plate 205 is fixedly connected to the middle position of the top of the upper mold 206, and the upper mold 206 is located directly above the lower mold 102.

[0035] Among them, the front end position of the opposing block 202 sliding on the left side of the support frame 2 is fixedly connected to the rear end position of the L-shaped support frame A3, the top left position of the support frame A3 is fixedly connected to the limiting slide plate A301, and the right side position of the limiting slide plate A301 is provided with a sliding groove, and the bottom position of the support frame A3 is fixedly connected to the motor A302, and the top rotating shaft of the motor A302 is fixedly connected to the angle support piece A303, the angle support piece A303 is located at the upper end position of the support frame A3, and the other end position of the angle support piece A303 is rotatably connected to one end of the connecting piece A304, and the other end position of the connecting piece A304 is rotatably connected to the rear end position of the cutting saw A305, the saw blade position of the cutting saw A305 is flush with the top height of the lower mold 102, and the cutting saw A305 is slidably connected in the sliding groove of the limiting slide plate A301.

[0037] When in use: When in use, first assemble the device in combination with the embodiment. When it is necessary to prepare plastic products, first place the material on the lower mold 102, then rotate the screw 103, and the screw 103 cooperates with the threaded hole in the middle position of the front end of the limit frame 1 to drive the lower mold 102 to move backward in the groove of the limit frame 1 until the rear end position of the lower mold 102 is aligned with the rear end position inside the groove of the limit frame 1. At this time, the lower mold 102 will be located directly above the upper mold 206. Next, start the bidirectional motor 201, and the two opposing blocks 202 are moved and expanded in opposite directions through the threaded shafts on both sides of the bidirectional motor 201. When the two opposing blocks 202 expand in opposite directions, the opposing plates 204 are driven to move downward through the cooperation of the two linkage frames 203 until the upper mold 206 is aligned with the lower mold 102, completing the plastic product production steps.

[0038] When it is necessary to demould the plastic product in the lower mold 102, start the motor A302 and the motor B402 respectively.

Next, start the bidirectional motor 201 to reverse. The cooperation between the rotating shafts on both sides of the bidirectional motor 201 and the two opposing blocks 202 makes the two opposing blocks 202 move towards each other. When the opposing blocks 202 approach each other, the two linkage frames 203 cooperate to drive the opposing plates 204 to move upward until the upper mold 206 is separated from the lower mold 102. At the same time, the position of the saw blade of the cutting saw A305 is flush with the top height of the lower mold 102 and the position of the saw blade of the cutting saw B405 is flush with the top height of the lower mold 102. When the two opposing blocks 202 approach each other, the saw blades of the cutting saw A305 and the cutting saw B405 are close to each other to cut and remove the burrs on the plastic product at the top position of the lower mold 102, and then the burrs on the top of the plastic product are cut during the demolding step, avoiding the secondary processing link.

[0039] Combined with the synchronous start of motor A302 and motor B402, there will be no interference between the saw blades of cutting saw A305 and cutting saw B405 during movement, ensuring that the saw blades of cutting saw A305 and cutting saw B405 cut the top position of the plastic product formed inside the lower mold 102. After the saw blades of cutting saw A305 and cutting saw B405 cut the plastic product inside the lower mold 102, the screw 103 is rotated to drive the lower mold 102 to move forward in the groove of the limit frame 1, thereby making the position of the lower mold 102 separate from the lower position of the saw blades of cutting saw A305 and cutting saw B405, so as to facilitate its demolding.

[0040] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
