The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0027] like Figure 1 and Figure 2 As shown, the batch molding mold includes a block-shaped mold body 1.
[0028] The mold body 1 has a product injection cavity 2 and an injection channel 3. The product injection cavity 2 is located at the upper part of the mold body 1 and has an opening at the upper end. The outer end of the injection channel 3 is located at the upper part of the mold body 1 and is adjacent to the product injection cavity 2. The injection channel 3 is located inside the mold body 1 and is connected to the product injection cavity 2. The mold body 1 also includes a plunger 5 and a push rod 6. The plunger 5 is connected to the outer end of the injection channel 3 and can block the outer end of the injection channel 3. The lower part of the outer end of the product injection cavity 2 and the injection channel 3 each has a corresponding push rod 6.
[0029] Initially, the plunger 5 is not connected to the outer end of the injection channel 3. At this time, the molten material is fed into the injection channel 3, and the material enters the product injection cavity 2 along the injection channel 3.
[0030] After the material is poured in, the plunger 5 is connected to the outer end of the injection channel 3. After a set time, the material is formed. At this time, the ejector rod 6 moves upward under the action of external force, thereby stably removing the formed workpiece and residue from the injection channel 3 of the mold body 1.
[0031] The injection channel 3 is arc-shaped.
[0032] The arc-shaped injection channel 3 not only enables the material to smoothly enter the product injection cavity 2, but also enables the residual material after molding to be conveniently discharged from the injection cavity.
[0033] The inner end of the injection channel 3 is smaller in size than the outer end, and the inner end of the injection channel 3 smoothly transitions to the outer end.
[0034] Such a structure facilitates the discharge of residual material in the injection channel 3, and also enables the material to enter the product injection cavity 2 at an appropriate speed.
[0035] The outer end of the injection channel 3 is matched with the plunger 5.
[0036] Such a structure enables the plunger 5 to stably block the outer end of the injection channel 3.
[0037] The plunger 5 comprises a first body 5a in the shape of a sheet, a second body 5b and a third body 5c, the first body 5a is vertically arranged, the second body 5b and the third body 5c are respectively fixedly connected at two sides of the first body 5a, the second body 5b is in the shape of a trapezoid, and the large bottom side of the trapezoid-shaped second body 5b is flush with the two sides of the first body 5a, the width dimension of the third body 5c is smaller than that of the first body 5a, when the plunger 5 is connected to the mold body 1, the second body 5b is located at the outer end of the injection channel 3, and the ejector rod 6 is located directly below the third body 5c.
[0038] Since the second body 5b is flush with the edges of the first body 5a, it can stably block the outer end of the injection channel 3 under the action of the first body 5a and the second body 5b. The third body 5c serves the function of contacting the ejector rod 6, so as long as the third body 5c can contact the ejector rod 6, the width dimension of the third body 5c can be relatively narrow, thereby avoiding the consumption of a large amount of material while ensuring stable contact with the ejector rod 6.
[0039] The first body 5a, the second body 5b and the third body 5c are in an integrated structure.
[0040] This can appropriately improve the compactness of the structure of the plunger 5.
[0041] The second body 5b has a smooth transition chamfer or round corner at the corner.
[0042] The second body 5b is in the shape of a rectangle, and the chamfer or round corner at the corner of the second body 5b can eliminate sharp structures.
[0043] The length dimension of the ejector rod 6 is greater than the thickness dimension of the mold body 1.
[0044] The structure can stabilize the force on the lower end of the ejector pin 6 and the upper end of the ejector pin 6 can stably push the corresponding product or residue.
[0045] The product injection cavity 2, the injection channel 3 and the corresponding ejector pin 6 form a molding unit, and the mold body 1 has a plurality of molding units.
[0046] The plurality of molding units can effectively improve the operation efficiency.
[0047] The ejector pin 6 opposite to the product injection cavity 2 is located at the center of the product injection cavity 2.
[0048] During the pushing of the product, the product is balanced.
[0049] The present batch molding mold can reduce the occupied space of the entire molding unit on the mold body due to the arc-shaped injection channel, and therefore, a larger number of molding units can be arranged in the limited position of the mold body, thereby improving the operation efficiency.
[0050] Meanwhile, the arc-shaped injection channel can also facilitate the exit of the molded residue, and the demolding stability is also relatively high.
[0051] In addition, the plunger can not only stably block the outer end of the injection channel, but also the structure of the body 3 can reduce the material consumption of the entire plunger, appropriately reduce the cost of the entire mold, and has high practical value.
[0052] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present disclosure.
[0053] Those skilled in the art should recognize that the above embodiments are used to illustrate the present application, and are not used as a limitation of the present application, and as long as the above embodiments are appropriately changed and varied within the scope of the present application, they fall within the scope of the present application.
